Brain’s lateral habenula may be source of lack of motivation in depressed
The brain's lateral habenula may be the source of lack of motivation in the depressed. (iStock photo) Researchers at the University of California, Berkeley, have identified biomarkers - genes and specific brain circuits in mice - associated with a common symptom of depression: lack of motivation. The finding could guide research to find new ways to diagnose and potentially treat individuals suffering from lack of motivation and bring closer the day of precision medicine for psychiatric disorders like depression.

Widely used health care prediction algorithm biased against black people
The new study found that a type of software program that determines who gets access to high-risk health care management programs routinely lets healthier whites into the programs ahead of blacks who are less healthy. (UC Berkeley graphic by Hulda Nelson) From predicting who will be a repeat offender to who's the best candidate for a job, computer algorithms are now making complex decisions in lieu of humans.

Cells linked to leading cause of blindness in elderly
Age-related macular degeneration is one of the leading causes of blindness in the elderly, affecting more than 2 million people in the United States and leading to progressive loss of central vision. Genome wide studies have identified almost three dozen genes that play a role in the disease, but exactly where in the eye they inflict damage was not well known.

20th century views and responses to drug use are no longer fit for purpose
A report from The Lancet calls for a new international approach to drug use - using evidence-based policies, which adapt faster, and respond more humanely and effectively to new drugs and their changing availability and patterns of use. The five-paper Series publishes as the opioid crisis continues, cannabis legalisation expands, global stimulant problems grow, and the number of new psychoactive substances (NPS) identified continues to increase.

Trial will look at new Parkinson’s treatment for frequent falls
Researchers have been awarded funding to trial a new treatment for frequent falls in patients with advanced Parkinson's. In Parkinson's disease, some parts of the brain begin to deteriorate, leading to symptoms including balance problems, which can increase the chances of falls. A team from Imperial College London and Imperial College Healthcare NHS Trust have been awarded 250,000 from the Medical Research Council (MRC) to trial a surgical implant that alters nerve activity, which could improve movement and reduce the number of falls.

Researchers identify a new way to target treatment-resistant cancers
An international team of researchers has found a different way cancer becomes resistant to chemotherapy, suggesting a new target for drugs. Chemotherapy kills cancers cells by preventing them from multiplying and by inducing ‘cell death', a natural process that can be enhanced with drugs. One form of cell death, called ferroptosis - iron-dependent cell death - is caused by the degradation of fats (lipids) that make up the cell membrane.

New clinical research offers possibility of future rehabilitation for patients in vegetative and minimally conscious states
Non-invasive brain stimulation is to be trialed for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state. The study builds on promising results from the Centre for Human Brain Health at the University of Birmingham which suggested that non-invasive brain stimulation can improve the success of rehabilitation for non-responsive patients.

Global trial is first clear evidence that a widely available drug reduces head injury deaths
A low cost and widely available drug could reduce deaths in traumatic brain injury patients by as much as 20 per cent depending on the severity of injury, according to a major study carried out in collaboration with the University of Birmingham. The research, published in The Lancet, showed that tranexamic acid (TXA), a drug that prevents bleeding into the brain by inhibiting blood clot breakdown, has the potential to save hundreds of thousands of lives.

Diabetes: a next-generation therapy soon available?
Diabetes: a next-generation therapy soon available?
By identifying a protein that helps regulate blood glucose and lipids, researchers at UNIGE hope for the rapid development of treatments more effective than current insulin therapy. Insulin, a hormone essential for regulating blood sugar and lipids, is normally produced by pancreatic - cells. In many people with diabetes, however, pancreatic cells are not (or no longer) functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through daily insulin injections.

Potential answer to pain found in the mud
Potential answer to pain found in the mud
A sample of estuarine mud taken 16 years ago has yielded a potential new class of painkiller as potent as opioids, but without their disadvantages. Researchers from The University of Queensland and University of Sydney have filed a patent application for the potential drug, which is a modified version of a molecule found in a Penicillium fungus, and published their results in the scientific journal Proceedings of the National Academy of Sciences USA .

Estuarine waters hold promise in global pain-relief hunt
In a world first, a team of Australian-led researchers has discovered a uniquely shaped fungus in pristine waters, which may mimic opioids with fewer side-effects. It had been hoped that such a molecular structure might exist. The worldwide search for an opioid alternative has made a leap forward - with a scientific discovery in an Australian fungus indicating effective pain relief and the potential for a safer less addictive drug, helping address the opioid epidemic of deaths by overdose.

Inactive receptor renders immunotherapies ineffective
Inactive receptor renders immunotherapies ineffective
The aim of immunotherapies is to enable the immune system once again to fight cancer on its own. Drugs known as checkpoint inhibitors are already in clinical use for this purpose. However, they are only effective in about one third of patients. Based on analysis of human tissue samples, a team from the Technical University of Munich (TUM) has now discovered one reason why this is so: an inactive receptor in cancer cells prevents the drugs from reactivating the immune system.
