Previous article: What are health inequalities? Next article: Ethnic inequalities . Welcome to the second article in a series of articles about health inequalities. This article will look more in detail at what socioeconomic health inequalities are. Introduction Socioeconomic factors refer to the circumstances in which people are born, grow, live, work, and age. These conditions are often considered the wider determinants of health, and are a fundamental cause of health inequalities. These inequalities are not accidental; they are the result of underlying structural disparities, occurring as a result of unequal distribution of resources and opportunities in society. Addressing these disparities requires coordinated, cross-government action across a wide range of policy areas, including prevention and focused work on the wider determinants of health. How income is linked to health Poverty and financial insecurity have a significant negative impact on health, as living on a low income is a source of stress. It also affects an individual's ability to afford health-improving goods, from nutritious food to gym memberships. Across the income spectrum, lower incomes are associated with worse self-reported health. Data from the Department for Work and Pensions’ Family Resources Survey 2023/24 shows that 43% of people on the lowest income rate their health as fair, bad or very bad, compared with 31% in the middle (the fifth income decile) and 15% on the highest incomes. The Health Foundation has visualised this in Figure 1 . The impact on health is even greater when low pay persists for generations: children from households in the bottom fifth of income distribution are over 4 times more likely to experience severe mental health issues compared to those in the highest fifth. Furthermore, Black, Asian and Minority Ethnic (BAME) individuals are disproportionately affected and are more likely to live in poverty, have low incomes, and lower levels of wealth compared to White individuals. How housing links to health The places where people live and age can significantly influence their health. Affluent areas have more access to green and other public spaces, clean air, and affordable and active travel. In contrast, deprived areas often have less access to green space, higher concentrations of fast-food outlets, and limited availability of affordable and healthy food. Individuals living in deprived areas will most likely have poor-quality and overcrowded housing conditions, associated with an increased risk of cardiovascular and respiratory diseases, depression and anxiety. They may also experience fuel poverty, so they cannot afford to heat their home. BAME households are more likely than White households to live in overcrowded homes and to experience fuel poverty. Health outcomes and projections The consequences of socioeconomic inequalities can be seen in differences in health outcomes. People in more deprived areas experience major illness earlier in life and die younger: in England, individuals in the 10% most deprived areas are expected to develop major illness 10 years earlier compared to those in the 10% most affluent areas. They are also over three times more likely to die prematurely before the age of 70. This inequality is projected to continue through to at least 2040, with no expected improvement. These findings are supported by research which looked at the impact of socioeconomic factors on the COVID-19 pandemic. Results showed that unequal access to healthcare amplified COVID-19 cases. It meant that a significant portion of cases, which could have been prevented through timely diagnosis, treatment, and resource distribution, contributed to an overall case rate that was 6-fold higher than it otherwise might have been. Additionally, a small group of long-term conditions contributes to most diagnosed health inequalities: chronic pain, chronic obstructive pulmonary disease (COPD), type 2 diabetes, cardiovascular diseases (CVD), and anxiety and depression. The prevalence of these conditions is 1.5 times higher in the 10% most deprived areas compared to the least deprived areas. The Health Foundation has visualised this in Figure 2 . Conclusion Socioeconomic health inequalities are fundamentally caused by the structural inequalities discussed throughout this article. Actions to address these disparities must be specifically targeted in the most deprived areas, which often see a disproportionate impact on BAME individuals. The next article in this series will look more in detail at ethnic health inequalities, so watch out for that!

In wound care Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The bright future of smart bandages 04/07/25, 13:57 Last updated: Published: 19/09/23, 17:30 In wound care Although wounds may seem miscellaneous to the naked eye, they can pose a great threat to the healthcare system, by overburdening health services through infections. Thus, it is essential to navigate wound care thoroughly to reduce burden and increase patient quality of life. Wounds can be caused by an array of different reasons and pose such a great threat because of the limited ways we’ve had to treat them which has resulted in issues such as antibiotic resistance, allergic reactions and so on. In recent times to enable higher quality treatment, a new invention known as the “smart bandage” has been made which uses nothing but light-emitting diode (LED) at its disposal to promote wound healing! The smart bandage is wireless and uses ultraviolet C radiation light (UVC) to sterilise wounds and prevent the risk of infection. This in turn decreases the chances of nosocomial incidences as well as opening doors for disinfection other than antibiotics or chemical based methods. The smart bandage is embedded with light emitting diodes called LEDs which emit UVC wavelength around 265-285nm using a controller. The smart bandage operates by effectively manipulating UVC’s germicidal and antimicrobial properties. Researchers produced a coil which is inductive and flexible so that the technology would easily be inserted into conventional fabric bandages. Wireless power via magnetic resonance is used by the coil so that the UVC LED’s can be powered without batteries being used. A second coil wirelessly transmits power to the inductive coil via electrical mains so that the LED is continuously receiving power supply till the required bacteria in the wound are eradicated. Scientists tested this technology on pathogens like Pseudoalteromonas sp , which are bacteria associated with bloodstream infections, surgical areas as well as wounds. Once the bacteria were cultured and grown, UVC LEDs were exposed to the culture which in turn resulted in the decreased growth of bacterial cells and within six hours completed stopped their growth by causing DNA damage leading to apoptosis of the bacterial cells. Currently, many wound treatment protocols involve the use of antibiotics which over time can lead to antibiotic resistance, thus straining health services by increasing hospital stays. The use of UVC based bandages not only decreases the risk of these consequences but is also environmentally friendly due to its low operating cost and reusability. Figure 4 also demonstrates added advantages of this technology. Looking forward, the revolutionary ability of smart bandages is undeniable. Currently, there is ongoing research being conducted into integrating a monitoring device which also has the capacity to send live data to healthcare professionals regarding the wound being treated. However, the results from this study are still to be replicated and tested in clinical studies. Although these innovations exhibit much promise by providing more flexible and higher quality care for patients, it is still in its infancy. But, it cannot be left unstated that the power of LED’s is remarkable, not only in their ability to treat but also in being economically beneficial.

Exploring neuroplasticity after brain injury Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Can we really ‘rewire’ our brain? Last updated: 06/05/26, 21:11 Published: 07/05/26, 08:00 Exploring neuroplasticity after brain injury Can the brain really rebuild what has been lost after a brain injury? This idea derives from neuroplasticity – the nervous system’s capacity to change and adapt, reorganising its connections and overall structure as a result of an experience. In other words, the brain strengthens, weakens, and forms new neural connections over time. In psychology, neuroplasticity is crucial for understanding learning, as repeated behaviours and thoughts can strengthen neural pathways, resulting in increased automatic responses. Neuroplasticity plays a large role in recovery following a brain injury. Joy & Carmichael (2020) found that after a stroke, the brain becomes temporarily plastic, during which new axons and synapses may form, functions can be reassigned to undamaged brain regions, and the brain becomes flexible to training, allowing for recovery. A key takeaway is that after a stroke, the brain not only repairs itself but also enters a temporary state of reorganisation and recovery. Repeated practice during rehabilitation supports the formation of new pathways, helping lost skills to be regained. This is a core psychological principle: learning requires repetition, and without it, new neural pathways will not be produced or maintained. This reorganisation is driven by cellular processes that modify neural connections. Specialised immune cells, known as microglia, reshape connections between neurons and assist in incorporating new cells into preexisting networks, as demonstrated by Sandvig et al. (2018). This emphasises that recovery is not solely biological but also behavioural, as the way one interacts with their environment influences the way the brain reorganises itself. For example, when an individual performs a behaviour, such as moving their leg in rehab, neural pathways for that certain behaviour are activated frequently. Here, microglia respond to this activity by strengthening frequently used connections and removing unused ones, a process known as “use it or lose it”, in relation to neural pathways. So, can we really ‘rewire’ our brains? Yes, but to an extent! Neuroplasticity illustrates that the brain is capable of change, through reinforced behaviour and experience, though it should be noted that this process rarely results in complete normalcy. From a psychological perspective, neuroplasticity highlights that recovery is about how behaviour, experience, and learning intertwine to allow the brain’s ability to adapt.

Nanogels are tiny, water swollen polymer networks and encapsulate therapeutic agents Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Nanogels: the future of smart drug delivery Last updated: 17/07/25, 11:54 Published: 17/07/25, 08:00 Nanogels are tiny, water swollen polymer networks and encapsulate therapeutic agents Nanomedicine is a rapidly advancing field, with nanogels emerging as promising innovations for drug delivery applications. Nanogels are soft nanoscale hydrogels that are transforming how we deliver drugs and treat diseases. Whilst hydrogels themselves have long been used in biomedical applications such as tissue engineering and wound healing, their relatively larger sizes (above 100 micrometres) limits their ability to interact with cells and cross biological barriers. Nanogels, however, are thousands of times smaller, and offer unique advantages as a result. What are nanogels? Nanogels are tiny, water swollen polymer networks and are made up of crosslinked polymer chains to form a 3D matrix. Nanogels can encapsulate therapeutic agents inside their porous core shell structure. This swelling allowing nanogels to carry payloads, such as drugs, proteins, nucleic acids and these cargo materials are protected from degradation in the body whilst enabling controlled and targeted delivery. Due to their small sizes, nanogels can penetrate tissues and even enter cells, which overcomes the limitations faced with hydrogels. The surface of nanogels can also be engineered for specificity, to allow for precise targeting of drugs to receptors on diseased cells or inflamed tissues. Advantages over other nanocarriers Compared to liposomes and polymeric micelles, nanogels have a larger inner surface, which means they can carry more payload. The higher loading capacity improves the therapeutic efficiency whilst reducing the risks of side effects cause by off-target drug release. Nanogels also undergo the enhanced permeability and retention (EPR) effect - a phenomenon where the nanoparticles naturally accumulate in tumour or inflamed tissues due to leaky blood vessel, and as a result this improves drug delivery to targeted disease sites. Stimuli responsive ‘smart’ nanogels A key feature of nanogels is their stimuli responsiveness, or ability to act as ‘smart’ materials. The nanogels can be designed to respond to environmental triggers such as changes in pH, temperature, light, redox conditions, pressure and more. This responsiveness enables controlled release of drugs exactly when and where they are needed12. For example, thermoresponsive nanogels can change their structure at body temperature or when exposed to localised heating, making them ideal for applications like wound healing and cancer therapy. This controlled release prevents premature drug leakage, reduces systemic toxicity and overall improves the precision of the treatment. The future of nanogels in medicine Nanogels have huge potential as customisable drug delivery systems to target specific disease systems. They are biocompatible, stable, and have high drug loading capacities and are stimuli responsive; these properties combined make them a powerful tool in applications such as targeted drug delivery and gene therapy. As nanomedicine research progresses, nanogels are set to revolutionise healthcare with smarter, safer and more targeted therapies.

Landing on the moon (again!) Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Artemis: the Lunar South Pole Base 01/04/26, 12:19 Last updated: Published: 13/01/24, 15:44 Landing on the moon (again!) Humans have not visited the moon since 1972, but that’s about to change. Thanks to NASA’s Artemis missions, we have already taken the first small step towards our own lunar home for astronauts. NASA has established the second generation of its lunar missions- “Artemis”, fittingly named after the ancient Greek Goddess of the Moon, and Apollo’s twin. The ultimate aim of the Artemis missions is to solidify a stepping stone to Mars. Technologies will be developed, tested, and perfected, before confidence is built to travel on to Mars. NASA has to consider the natural conditions of the Moon, since doing so will allow astronauts to limit their reliance on resources from Earth, and increase their length of stay and therefore potential for research. The amount achieved would be extremely limited if a lunar mission relied solely on resources from Earth, due to the limitation of rocket payloads. This is known as In-Situ Resource Utilisation, and in addition to extended lunar stays, its success on the Moon is essential if we hope to one day establish a base on Mars. As a priority, astronauts need to have access to energy and water. Luckily, the conditions at the lunar south pole may be ideal for this. Unlike Earth, where we experience seasons due to its 23.5° tilt, the Moon’s tilt is tiny, at only 1.5°. This means some areas at the lunar poles are almost always exposed to sunlight, providing a reliable source of solar energy generation for a potential Artemis Base Camp. And since the Sun is always near the horizon at the poles, there are even areas in deep craters that never see the light. These areas of “eternal darkness” can reach temperatures of -235°, possibly allowing astronauts access to water ice. Aside from access to resources, Artemis has to consider the dangers that come from living in space. Away from the safety of Earth’s protective atmosphere and magnetosphere, astronauts would be exposed to harsh solar winds and cosmic rays. To combat this, NASA hopes to make use of the terrain surrounding the base, highlighting another advantage of the hilly south pole. The exact location for the Artemis Base is currently undecided. We just know it will most likely be near a crater rim by the south pole, and on the Earth-facing side to allow for communication to and from Earth. Not only is the south pole ideal from a practical standpoint, it is also an area of exciting scientific interest. Scientists will have access to the South Pole–Aitken basin, not only the oldest and largest confirmed impact crater on the Moon, but the second largest confirmed impact crater in the entire Solar System. With a depth of up to 8.2 km, and diameter of 2500 km, it is thought this huge crater will contain exposed areas of lower crust and mantle, providing an insight into the Moon’s history and formation. Additionally, thanks to areas of “eternal darkness” the ice water found deep within craters at the south pole may hold trapped volatiles up to 3.94 billion years old, which, although not as ancient as previously expected, can still provide an insight into the evolution of the Moon. The scientific potential of the Artemis Base Camp extends far beyond location specific investigations to our most fundamental understanding of physics, from Quantum Physics to General Relativity. Not to mention the astronauts themselves, as well as “model organisms” which will be the focus of physiological studies into the effects of extreme space environments. Artemis Timeline Overview Artemis 1 launched on 16th November 2022. It successfully tested the use of two key elements of the Artemis mission- Orion and the Space Launch System (SLS)- with an orbit around the moon. Orion, named after the Goddess Artemis' hunting partner, is the spacecraft that will carry the Artemis crew into lunar orbit. It is carried by the SLS, NASA’s super heavy-lift rocket, one of the most powerful rockets in the world. The original plans to launch Artemis 2 in late 2024 were delayed due to a helium flow issue in the rocket’s upper section. These technical issues pushed the launch date for the first crewed Artemis mission back to 1st April 2026. This 10-day journey includes a lunar flyby, bringing the four astronauts further than humans have ever travelled beyond Earth. Artemis 3 is planned for mid-2027. This mission, no longer crewed, will be a low-Earth orbit, aiming to test important technologies and equipment. Artemis 4 plans to launch in 2028. The mission will include the first use of Gateway, another key element to the Artemis missions. Gateway will be a multifunctional lunar space station, designed to transfer astronauts between Orion and HLS, as well as hosting astronauts to live and research in lunar orbit. Gateway will be constructed over Artemis 4-6 , with each mission completing an additional module. NASA plans to have Artemis missions extending for years beyond this, with over 10 proposed and more expected. Eventually we will have a working base on the Moon with astronauts able to stay for months at a time. Having already started a year ago, Artemis will continue to expand our horizons. We can look forward to uncovering long held secrets of the Moon, and soon, setting our sights confidently on Mars.

Using the new technology AI to develop drugs Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Artificial Intelligence in Drug Research and Discovery 09/07/25, 11:56 Last updated: Published: 24/05/23, 11:20 Using the new technology AI to develop drugs Drug research has been transformed by artificial intelligence (AI), which has become a game-changing technology in several industries. Only a small portion of potential drugs make it to the market after the lengthy and expensive traditional drug discovery process. A drug's discovery and development can take over ten years and cost an average of US$2.8 billion. Even then, nine out of 10 medicinal compounds fall short of passing regulatory approval and Phase II clinical trials. The use of AI in this process, however, has the potential to greatly improve effectiveness, accuracy, and success rates. Given that AI can help with rational drug design, support decision-making, identify the best course of treatment for a patient, including personalised medicines, manage the clinical data generated, and use it for future drug development, it is reasonable to assume that it will play a role in the development of pharmaceutical products from the laboratory bench to bedside table. There are several ways in which AI is currently being used to enhance the drug discovery process. One of the primary applications is virtual screening ( Figure 2 ), which involves using machine learning algorithms to analyse large libraries of chemical compounds and predict which ones are likely to be effective against a specific disease target. This can significantly reduce the time and cost required for drug discovery by narrowing down the number of compounds that need to be tested in the lab. Another way AI is being used in drug discovery is through generative models, which use deep learning algorithms to design molecules that are optimised for specific therapeutic targets. This approach can be used to design molecules that are effective against a specific target while also minimising toxicity or other undesirable properties. Data analysis is another area where AI can be applied in drug discovery. By analysing large datasets of biological and chemical information, AI can help researchers identify patterns and relationships that may be relevant to drug discovery. For example, AI can be used to analyse genomic data to identify potential drug targets or to analyse drug-drug interactions to identify potential safety issues. However, one of the main challenges is the need for high-quality data, as AI models rely on large amounts of data to make accurate predictions. Additionally, there is a risk that AI models may miss important insights or make incorrect predictions if the data used to train them is biased or incomplete. Nevertheless, the continued development of AI and its amazing tools seeks to lessen the difficulties experienced by pharmaceutical firms, impacting both the medication development process and the full lifecycle of the product, which may account for the rise in the number of start-ups in this industry. The importance of automation will increase as a result of using the most up-to-date AI-based technologies, which will not only shorten the time needed for products to reach the market but also enhance product quality, increase overall production process safety, and make better use of available resources while also being cost-effective. In conclusion, the use of AI in drug discovery has the potential to revolutionize the field and significantly improve the success rate of potential drug candidates. Despite the challenges and limitations, the continued research and development of AI in drug discovery will undoubtedly lead to faster, cheaper, and more accurate drug development.

Cultural beliefs, stigma, family values and more, inhibit open discussion of mental health Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Addressing mental health within the South Asian community Last updated: 05/03/26, 14:56 Published: 22/05/25, 08:00 Cultural beliefs, stigma, family values and more, inhibit open discussion of mental health Mental health is a critical aspect of human life, yet it remains a deeply taboo subject within the South Asian community. Despite the growing awareness in mainstream discourse, many South Asians—especially those living in diasporic communities such as the UK, the US, and Canada—continue to face significant barriers when it comes to recognising, understanding, and seeking help for mental health concerns. But why does this silence continue? The answer lies in a combination of cultural beliefs, stigma, family values, societal expectations, and a general lack of education, especially among the older generations. Unlike Western cultures, which tend to emphasise individualism, South Asian societies often focus on collectivism, where the success and well-being of the family take precedence over the individual. This cultural foundation has both strengths and challenges. While it preaches community and support, it also discourages expressions of emotional vulnerability, especially when that vulnerability may be perceived as bringing shame or dishonour to the family. Mental health is often viewed as a personal weakness, a spiritual failing, or something that reflects poorly on one’s upbringing or family reputation. A survey conducted by the NHS in the UK revealed that 35% of South Asian youth aged 18–24 reported experiencing some form of mental health issue, compared to 30% of White British youth. While these figures suggest a slightly higher incidence, what is more alarming is the disparity in access to care and treatment. Many South Asians are less likely to seek help due to fears of being perceived as 'crazy' or weak. In some cases, mental health symptoms are dismissed as temporary mood swings, spiritual crises, or simply a lack of willpower. A study published by the Mental Health Foundation (2020) found that only 32% of South Asians surveyed had a functional understanding of mental health, compared to 60% of the general UK population. This suggests that stigma is caused by a lack of knowledge, which prevents early intervention and exacerbates untreated conditions. Among those who recognise they have a problem, there is often a reluctance to seek professional help, particularly from psychologists or psychiatrists. Instead, some may turn to spiritual leaders or rely solely on familial support, both of which, while culturally significant, may not always offer the necessary therapeutic intervention. One of the major mental health concerns within the South Asian community is depression and anxiety, and these conditions often go undiagnosed. Research from the Centre for Mental Health has indicated that South Asian individuals are more likely to report symptoms of depression and anxiety than their White counterparts, but are less likely to receive treatment. According to a 2022 study by Public Health England, South Asian women are 1.5 times more likely to suffer from common mental health disorders, such as anxiety and depression, but only 13% accessed mental health services compared to 25% of White British women. Many culturally specific factors contribute to higher rates of anxiety and depression in South Asian communities. These include intergenerational trauma, immigration stress, identity conflict, and pressures related to marriage, family reputation, and academic or career success. Young South Asians often find themselves navigating between traditional family expectations and Western societal norms, leading to identity struggles that can trigger chronic stress and anxiety. Additionally, gender roles in South Asian cultures often impose strict expectations on behaviour. Women may be discouraged from voicing emotional distress, as they are expected to be nurturing and self-sacrificing. Men, on the other hand, are often pressured to appear strong and unemotional, which leads to a culture where expressing vulnerability is equated with failure. These rigid expectations prevent both genders from openly discussing their struggles or seeking help. Barriers to accessing mental health services are not only cultural but also structural. Many South Asians, particularly first-generation immigrants, may face language barriers when communicating with healthcare providers. There is also a lack of culturally competent therapists who understand the nuances of South Asian traditions, values, and family structures. Without representation or relatability, individuals may feel misunderstood or alienated by the mental healthcare system. Despite these challenges, there is hope. The rise of South Asian mental health advocates, community-based initiatives, and culturally tailored therapy programs is slowly helping to dismantle stigma. Social media has also played a vital role in bringing these conversations to the forefront, especially among Gen Z and Millennials. Many people are now speaking out and sharing their stories and experiences, which helps shift the narrative within the South Asian Community. We can help break the stigma surrounding mental health in the South Asian community by raising awareness, educating others, and normalising conversations around emotional wellbeing. It starts at the grassroots level: in homes, schools, religious institutions, and workplaces. Encouraging open dialogue and fostering environments where individuals feel safe to share their experiences without judgment is key. More importantly, we must validate the struggles of those suffering from mental health issues—telling them that it is okay to not be okay, and that seeking help is a sign of strength, not weakness. Furthermore, the government and health services can do more! They should invest in culturally sensitive mental health resources, including multilingual therapy options and outreach programs tailored specifically for South Asian populations. In conclusion, addressing mental health within the South Asian community requires a collective effort to challenge outdated norms, educate people across all age groups, and improve access to inclusive and empathetic mental healthcare. Depression, anxiety, and other mental illnesses are not signs of weakness; they are real, treatable conditions that deserve compassion and support. Only by acknowledging this and working together can we begin to transform the narrative and create a healthier, more open future for the South Asian community, letting the future generation have a safe and open space to talk and get help for their mental health!

How metal compounds can be used as anti-cancer agents Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Anticancer Metal Compounds 04/04/26, 16:58 Last updated: Published: 23/05/23, 09:17 How metal compounds can be used as anti-cancer agents Metal compounds such as platinum, cobalt and ruthenium are used as anticancer agents. Anticancer metal compound research is important as chemotherapy is not selective, being very toxic to patients damaging normal DNA cells. Such metal compounds act as anti-cancer agents with the metals being able to vary in oxidation states. Selectivity of metal compounds to target only cancer cells arises from the metals properties of varying oxidation states for redox reactions. As cancer exists in hypoxic environments, the oxidation state of the metal is able to vary releasing the cancer drug only in the cancer environment. For example prodrugs are relatively inert metal complexes with relatively high oxidation states. PtIV, and CoIII are selective carriers undergoing reduction by varying the metals oxidation state in cancerous hypoxic environments releasing anticancer drugs. CoIII reduced to CoII, PtIV reduced to PtII in hypoxic environments. CoIII two oxidation states: Cobalt (III) is kinetically inert with low-spin 3d6 configuration, CoII is labile (high-spin 3d7). When CoIII is reduced to CoII in hypoxic environments, the active molecule is released then restored to its active form killing cancer cells. Cobalt can also bind to ligands like nitrogen mustards and curcumin ligands, exhibiting redox reactivity for cancer therapy. Nitrogen mustards are highly toxic due to their DNA alkylation and cross-linking activity. In vivo they are not selective for tumour tissue however can be deactivated by coordination to CoIII, released on reduction to CoII in hypoxic tumour tissue. This reduces systemic toxicity concluding an efficient anticancer drug. Platinum anticancer metal compounds treat ovarian, cervical and neck cancer. Platinum ( Pt IV) (cisplatin) exhibits redox-mediated anticancer activity, highly effective towards tumours. Platinum causes severe side-effects for patients so PtIV prodrug is used selectively reducing tumour sites. Ruthenium is used for cancer therapy as a less toxic metal over platinum. Ruthenium targeted therapy selectively disrupts specific cellular pathways where cancer cells rely for growth and metastasis. Reduction of Ru (III) to Ru(II) selectively occurs in hypoxic reducing environments where tumours over express transferrin receptors, ruthenium binding to. Since platinum is toxic, the latest efforts in research are developing ruthenium, gold, copper, and iron complexes that have higher specificity and reduced toxicity. Overall, metal compounds for cancer treatment attracted high interest due to redox activity properties. Metal compounds are selective to cancer cells, limiting patients' side effects. Such therapy shows how inorganic chemistry is important to medicine. Written by Alice Davey Related article: MOFs in cancer drug delivery Project Gallery

Go back Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The evolution of AI: understanding the role of NLP technologies Last updated: 11/04/26 Published: 08/05/23 Artificial intelligence (AI) has long been a controversial topic, with some people fearing its potential consequences. This has been exacerbated by popular culture, with movies such as The Terminator and 2001: A Space Odyssey depicting AI systems becoming self-aware and turning against humans. Similarly, The Matrix portrayed a dystopian future where AI systems had enslaved humanity. Fast forward to the present day- AI has become a normal part of our everyday life, whether we realise it or not. From virtual assistants like Siri and Alexa to personalised movie and product recommendations, AI-powered technologies have revolutionised the way we interact with technology. AI also plays a critical role in industries such as healthcare, finance, and transportation, with algorithms helping to analyse data, identify patterns, and make predictions that lead to better decision-making. As with any industry, the AI industry is very much prone to evolution. In fact, this is especially relevant for the AI industry, given that it engages user habits to learn and redefine its understanding. This has led to the introduction of unforeseen technologies. One of the most studied and developed AI modelling techniques, Natural Language Processing (NLP), has been particularly placed under focus recently with the emergence of technologies such as Open AI’s ChatGPT, Google’s Gemini (formerly Bard) AI and Microsoft’s Bing AI- known as Copilot. ChatGPT in particular, was one of the first technologies of this kind to garner significant fame. Within its first year of release, the GPT-3 model had more than 10,000 registered developers and over 300 applications built on its application programming interface (API). In addition, Microsoft acquired OpenAI's exclusive license to the GPT-3 technology in 2020, further solidifying its position as a leading language model in the industry. ChatGPT works as an advanced artificial intelligence technology designed to understand and process human language. Built on the GPT-3.5 architecture, it uses NLP to comprehend and generate responses that simulate human conversation. ChatGPT is classified as a large language model, which means it has been trained on vast amounts of data and can generate high-quality text that is both coherent and relevant to the input provided. While concerns have been raised about the potential impact of NLP technologies, there are several reasons why we should not fear their emergence. Firstly, NLP has already enabled a wide range of useful applications that have the potential to improve efficiency, convenience, and accessibility. Furthermore, the development and deployment of NLP technologies is subject to ethical considerations and regulations that aim to ensure their responsible use. NLP technologies are not designed to replace humans, but rather to complement and enhance human capabilities. While some jobs may be impacted by automation, new jobs are likely to emerge that require human skills that are not easily replicated by machines. Ultimately, the impact of NLP technologies depends on how they are developed and used. There are always likely to be risks, but by taking a proactive approach to their development and deployment, we can ensure that they are used to benefit society and advance human progress.

The role of CRISPR-Cas9 technology Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Reaching new horizons in Alzheimer's research 09/04/26, 18:09 Last updated: Published: 12/10/23, 11:50 The role of CRISPR-Cas9 technology The complexity of Alzheimer’s Alzheimer's disease (AD) is a formidable foe, marked by its relentless progression and the absence of a definitive cure. As the leading cause of dementia, its prevalence is expected to triple by 2050. Traditional therapies mainly focus on managing symptoms; however, advances in genetics research, specifically CRISPR-Cas9 gene-editing technology, offer newfound hope for understanding and treating this debilitating condition. The disease is characterized by progressive deterioration of cognitive function, with memory loss being its hallmark symptom. Primarily affecting individuals aged 65 and over, age is the most significant risk factor. Although this precise cause remains elusive, scientists believe that a combination of genetic, lifestyle and environmental factors contributes to its development. CRISPR’s role in Alzheimer’s research After the discovery of using CRISPR-Cas9 for gene editing, this technology is receiving interest for its potential ability to manipulate genes contributing to Alzheimer’s. Researchers from the University of Tokyo used a screening technique involving CRISPR-Cas9 to identify calcium, proteins, and integrin-binding protein 1, which is involved in the formation of AD. Furthermore, Canadian researchers have edited genes in brain cells to prevent Alzheimer’s using CRISPR. The team identified a genetic variant called A673T, found to decrease Alzheimer’s likelihood by a factor of four and reduce Alzheimer’s biomarker beta-amyloid (Aβ). Using CRISPR in petri dish studies, they managed to activate this A673T variant in lab-grown brain cells. However, the reliability and validity of this finding are yet to be confirmed by replication in animal studies. One final example of CRISPR application is targeting the amyloid precursor protein (APP) gene. The Swedish mutation in the APP gene is associated with dominantly inherited AD. Scientists were able to specifically target and disrupt the mutant allele of this gene using CRISPR, which decreased pathogenic Aβ peptide. Degenerating neurons are surrounded by Aβ fibrils, the production of Αβ in the brain initiates a series of events which cause the clinical syndrome of dementia. The results of this study were replicated both ex vivo and in vivo and demonstrated this could be a potential treatment strategy in the future. The road ahead While CRISPR technology’s potential in Alzheimer’s research is promising, its therapeutic application is still in its infancy. Nevertheless, with the aid of cutting-edge tools like CRISPR, deepening our understanding of AD, we are on the cusp of breakthroughs that could transform the landscape of Alzheimer’s disease treatment.
