Modern Humans Owe Enhanced Immunity & Allergies To Neanderthals

New research from two papers suggests that mating between two human species led to modern humans having the ability to resist infection. However, this might have had a downside: our vulnerability to allergies could have also increased. Both reports are published in the American Journal of Human Genetics. The human immune system is extremely powerful, able

Science Proves: Dogs Can Recognise Human Emotions

Vitamin D Supplements Might Be Harmful

Taking vitamin D supplements might be a bad idea, says Tim Spector, Professor of Genetic Epidemiology from Kings College, who cites a number of new research in an article on The Conversation. He lays great emphasis on studies linking high doses of the nutrient and increased risk of falls and fractures. Past studies have shown that

Portable Protein-Making Bioreactor Can Bring Medication To Remote Areas

Desperate situations have often brought about remarkable inventions. Such was how the challenges in providing medication to people living in remote regions of the globe fuelled the creation of a small, portable, protein-making bioreactor. Researchers from Oak Ridge National Laboratory describe the device in the journal Small. The bioreactor has been made such that it can produce a
