Why are some lung cancers more difficult to treat than others? A team of researchers may have found a new clue. A recent study found that two specific genetic mutations influence cancerous cells and make them more likely to resist treatment. The mutations concern the genes EGFR, which is involved in cell growth, and TP53, which helps regulate cell division and prevent tumours. Mutations in these proteins are often hallmarks of cancer which is why the team of researchers from the University College London (UCL), the UK-based Francis Crick Institute and AstraZeneca investigated them using mouse ...

The "sleep hormone" and common supplement melatonin could be linked to a decreased risk of age-related macular degeneration (AMD). AMD is a progressive eye condition affecting the macula, a small area near the centre of the retina, and can blur your central vision. There is no definitive cure for AMD but several treatments can help manage the condition and slow its progression. A team of researchers from the Case Western Reserve University School of Medicine and the Cole Eye Institute both based in the US looked at the health data of over 200,000 people, some at an early stage of the disease a...

Bioengineers have successfully developed sensors as fine as spider's silk. Researchers at the University of Cambridge in the UK say the extremely light sensors could be used to monitor human health, such as heartbeats, or to detect detailed changes in the environment. The sensors are 50 times thinner than human hair and so lightweight that the scientists were able to print the fibre directly onto a dandelion without it collapsing. In a recently published study, the sensor was tested to pick up signals such as heartbeats in the same way as an electrocardiogram (ECG). The research team says the ...

It takes a decade on average before a new medication arrives on the market. Now, the French start-up Yseop is trying to use generative artificial intelligence (GenAI) to speed up the process. Clinical trials often generate a huge amount of data, and it’s the job of medical writers to generate clinical trial protocols and final reports. How are new AI tools being used in doctors' offices?"They have to report how the clinical trial went, who the participants are, the details of the participants and they have to give details [about] the manufacturing, the stability of the manufacturing, the quali...

A new study has found that our brains are getting larger, which could be good news for reducing dementia risk. Researchers from the University of California analysed data from a cohort in the Framingham Heart Study (FHS) which started in 1948 in the US and originally consisted of 5,209 men and women between the ages of 30 and 62. The study has continued for 75 years, meaning that it now includes participants born during the 1930s through the 1970s. Though it was originally designed to study cardiovascular diseases, the researchers focused on MRI results of more than 3,200 people. Published in ...

Researchers have identified new drug candidates that may be able to prevent HIV-infected cells from escaping detection by the immune system. A team from the Univerisity of Pittsburgh School of Medicine in the US made the discovery. Current therapy, called antiretroviral therapy, prevents HIV from multiplying which reduces the virus’ amount in the body to an undetectable level but it isn’t a cure. “We have excellent antiretroviral drugs that suppress HIV, but unfortunately, none of them clear the virus. If someone with HIV stops taking their medication, the infection will rebound,” Thomas Smith...
