Over the past few decades, many bacteria have become resistant to existing antibiotics, and few new drugs have emerged. A recent study from a U.K. commission on antimicrobial resistance estimated that by 2050, antibiotic-resistant bacterial infections will kill 10 million people per year, if no new drugs are developed.
Raising 'good cholesterol' not as effective as lowering 'bad cholesterol'

- Category: Research
Low and very high levels of HDL, or "good cholesterol" are associated with a higher risk of dying from heart disease, cancer and other causes, according to a study in the Journal of the American College of Cardiology. The findings from the first of its kind study suggest that a low level of good cholesterol may not be a heart disease risk factor on its own and that raising HDL does not likely reduce a person's risk of heart disease.

Our Facebook status updates, 'likes' and even photos could help researchers better understand mental health disorders with the right ethical safeguards, argue researchers from the University of Cambridge, who suggest that social networks may even be used in future to provide support and interventions, particularly among young people.

- Category: Research
A new compound, discovered jointly by international pharmaceutical company Servier, headquartered in France, and Vernalis (R&D), a company based in the UK, has been shown by researchers at the Walter and Eliza Hall Institute and Servier to block a protein that is essential for the sustained growth of up to a quarter of all cancers.
Anti-inflammatory drugs could help treat symptoms of depression
- Details
- Category: Research
Anti-inflammatory drugs similar to those used to treat conditions such as rheumatoid arthritis and psoriasis could in future be used to treat some cases of depression, concludes a review led by the University of Cambridge, which further implicates our immune system in mental health disorders. Researchers from the Department of Psychiatry at Cambridge led a team that analysed data from 20 clinical trials involving the use of anti-cytokine drugs to treat a range of autoimmune inflammatory diseases.
Depriving deadly brain tumors of cholesterol may be their Achilles' heel
- Details
- Category: Research
Researchers at University of California San Diego School of Medicine, Ludwig Institute for Cancer Research and The Scripps Research Institute, with colleagues in Los Angeles and Japan, report that depriving deadly brain cancer cells of cholesterol, which they import from neighboring healthy cells, specifically kills tumor cells and caused tumor regression and prolonged survival in mouse models.
MS drug may reverse some physical disability
- Details
- Category: Research
A drug used to treat multiple sclerosis (MS), alemtuzumab, was found to reverse some of the physical disability caused by the disease, according to new research published in the October 12, 2016, online issue of Neurology®, a medical journal of the American Academy of Neurology. Because it can cause serious side effects, alemtuzumab is generally used in people who have not responded well to other MS drugs; however, in this study it was used relatively early in the course of MS.
