New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat more than five grams a day, the equivalent of 2.5 teaspoons of salt. Fewer than five per cent of individuals in developed countries exceed that level. The large, international study also shows that even for those individuals there is good news. However, the…
The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…
For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory…
Monash University’s Biomedicine Discovery Institute (BDI) researchers have identified a new mechanism used by Henipaviruses in infection, and potential new targets for antivirals to treat them. Their findings may also apply to other dangerous viruses.
Everyone knows what our brains look like – but why is it folded up like that? Looking at other species reveals much less folding or even none at all. Scientists in Dresden, Germany, have now taken a closer look at the ridges and grooves of human brains. They discovered what causes our brains to fold – and what happens when the folding process goes wrong.
Transgender individuals may be at higher risk for myocardial infarction and death due to cardiovascular disease, according to several studies. This increased risk may be due to the hormone therapy that transgender patients take for masculinization or feminization. A review authored by Michael S. Irwig, MD, associate professor of medicine at the George Washington University (GW) School of Medicine…
People who abstain from alcohol or consume more than 14 units a week during middle age (midlife) are at increased risk of developing dementia, finds a study in The BMJ today. However, the underlying mechanisms are likely to be different in the two groups. As people live longer, the number living with dementia is expected to triple by 2050. So understanding the impact of alcohol consumption on…
It doesn’t often happen that army generals switch sides in the middle of a war, but when cancer is attacking, it may cause even a gene that acts as the body’s master defender to change allegiance. Researchers at the Weizmann Institute of Science have discovered that this gene’s betrayal can occur in more ways than previously appreciated – and might even return the renegade cells to their…
Scientists conducting the first comprehensive study of key immune system cells—collected from West African Ebola survivors— have made a surprising discovery that provides important clues to developing effective vaccines against the infection.
Austrian researchers have accomplished an astounding feat: They created organoids that mimic the onset of brain cancer. This method not only sheds light on the complex biology of human brain tumors but could also pave the way for new medical applications.
The electromagnetic radiation emitted from smartphones and similar devices may have negative effects on the memory of young people. Research conducted in Switzerland suggests that it might be a good idea to get rid of your smartphone from time to time.
Antibiotics are mostly prescribed for acute respiratory infections (ARIs), yet most of these infections are viral. A new study shows that inappropriate antibiotics prescriptions are widespread, contributing dangerously helping antibiotic-resistant organisms to grow. Overuse could be due to attitudes among patients and clinicians, current George Washington University research suggests.
While soccer fans want to see which team really has their head in the game, the players themselves might want to watch out for the consequences of headers. They may be more likely to experience short-term balance problems, suggesting that repetitive head impacts could have the potential to cause subtle neurological deficits not previously known, according to a preliminary study.
CRISPR has recently become synonymous with precise genetic editing. However, the mighty tool has been known to fail from time to time. Now, researchers have found out why.
Adopting new guidelines for high blood pressure (hypertension) would dramatically increase the number of people labeled as having the condition and being recommended for drug treatment, finds a study published by The BMJ today. The findings show that, if the guidelines were introduced in the US and China, more than half of those aged 45-75 years in both countries would be considered hypertensive.
An unexpected discovery that could bring new hope to cancer patients worldwide: Researchers from the University of California San Diego have identified a mechanism that could predict response to immunotherapy. The most effective weapon against the tumors may be handed to the scientists by the cancer cells themselves.
More than two years after reports of skyrocketing Zika rates surfaced worldwide, questions still loom about this complicated virus. Professor of Biological Science Hengli Tang and his postdoctoral researcher Jianshe Lang from the Florida State University take a deep dive into the differences between Zika and the Dengue virus.
Administering needle-based procedures in anesthesiology is a complex and delicate procedure and the current training methods for doctors are costly and fall short in preparing them. Engineers have developed a low-cost, hand-held device that simulates the tactic feeling of the instrument passing through several layers of tissue.
Researchers at the University of Arizona College of Medicine – Phoenix are cross-utilizing plant biology, medicine and engineering to create a novel platform. They have developed a revolutionary "lung on a leaf" to study pulmonary diseases.
Another piece in the puzzle that is non-alcoholic fatty liver disease has been solved by a University of Queensland researcher in a step towards developing treatments for a disease that affects about one in every five Australians. PhD student Laurence Britton has discovered a pivotal mechanism by which iron is able to make the liver more vulnerable to the injury and metabolic dysfunction that…
Australia's national science agency CSIRO has identified a new gene that plays a critical role in regulating the body's immune response to infection and disease.
SLAC and Stanford researchers are developing a device that combines electrical brain stimulation with EEG recording, opening potential new paths for treating neurological disorders. It could help bring back lost brain function by measuring how the brain responds to therapies that stimulate it with electric current.
A team of neurobiologists has identified a novel neuronal circuit in the midbrain that gates fear learning. They think that associative learning of fear is mediated by a novel dopamine circui.
Canadian researchers have found a promising way to stop tumour cells from multiplying. In disrupting the composition of ribosomes, the team from Université de Montréal (UdeM) discovered a direct molecular mechanism to stop cancer cells from proliferating, which is called senescence. Their results have been published in Nature Cell Biology. “Ribosomes are complex machines composed of both…
Every cell and every organism ages sooner or later. But why is this so? Scientists at the German Cancer Research Center in Heidelberg have now discovered for the first time a protein that represents a central switching point in the aging process. It controls the life span of an individual - from the fly to the human being. This opens up new possibilities for developing therapies against…
