European wildcats, thought to be extinct 50 or so years ago in the Jura mountains, have since recolonised part of their former territory. This resurgence in an area occupied by domestic cats has gone hand-in-hand with genetic crosses between the two species. The hybridisation between wild and domesticated organisms is known to endanger the gene pool of wild species.
Loved or hated, the humble oat could be the new superfood for cancer patients as international research shows a diet rich in fibre could significantly reduce radiation-induced gut inflammation.
Conducted by the University of Gothenburg, Lund University and the University of South Australia, the preclinical study found that dietary oat bran can offset chronic gastrointestinal damage caused by radiotherapy, contradicting long-held clinical recommendations.
Climate warming will alter marine community compositions as species are expected to shift poleward, significantly impacting the Arctic marine ecosystem.
(Vienna, 29 September 2020) An antibody for treating advanced prostate cancer improves progression-free survival in patients with metastasised, castration-resistant prostate cancer. This is the finding of the long-term analyses of an international phase 3 clinical trial, recently published in the leading journal European Urology. The study showed that overall survival was 2 - 3 times higher than in the placebo arm.
New research led by Flinders University has found a link between beta-blockers and survival outcomes in some breast cancer patients.
Beta-blockers, commonly used to manage cardiovascular disease, were negatively associated with survival outcomes in patients with HER2 (Human Epidermal Growth Factor Receptor 2) positive advanced breast cancer, according to a new paper in the Frontiers In Oncology.
PHILADELPHIA-- Stopping the cannibalistic behavior of a well-studied enzyme could be the key to new drugs to fight age-related diseases, according to a new study published online in Nature Cell Biology. For the first time, researchers in the Perelman School of Medicine at the University of Pennsylvania show how the self-eating cellular process known as autophagy is causing the SIRT1 enzyme, long known to play a role in longevity, to degrade over time in cells and tissue in mice.
Shannon Meseck, a NOAA Fisheries research chemist and marathon runner, was initially interested in how ultra-runners can tolerate higher levels of carbon dioxide than non-athletes. A chance conversation with a medical doctor about ciliated cells in the human lung turned on a light bulb in her head. Could similarities between the function of these cells in humans and in blue mussels explain the mussels' response to increasing acidification in the ocean?
Working memory: it's how you make a mental shopping list without forgetting the milk, or memorize a number just long enough to write it down. But working memory is more than a prerequisite for a successful errand--the ability to briefly hold information in our minds lies at the heart of almost everything we do.
And, as a new study of forgetful mice shows, the brain processes behind this skill are more complex than commonly appreciated.
Skoltech researchers have proposed a fast and accurate numerical method of addressing the problem plaguing electroencephalography (EEG) studies that monitor the brain's electrical activity -- having to laboriously locate the source of EEG signal in the brain due to the low spatial resolution of this method. The new approach may help improve both medical and research applications of EEG. The paper was published in IEEE Transactions on Biomedical Engineering.
The power of the sun, wind and sea may soon combine to produce clean-burning hydrogen fuel, according to a team of Penn State researchers. The team integrated water purification technology into a new proof-of-concept design for a sea water electrolyzer, which uses an electric current to split apart the hydrogen and oxygen in water molecules.
This new method for "sea water splitting" could make it easier to turn wind and solar energy into a storable and portable fuel, according to Bruce Logan, Kappe Professor of Environmental Engineering and Evan Pugh University Professor.
A previously banned insecticide, which was approved for agricultural use last year in the United States, is harmful for bees and other beneficial insects that are crucial for agriculture, and a second pesticide in widespread use also harms these insects. That is according to a new analysis from researchers at The University of Texas at Austin.
Girls - but not boys - who participate actively in school sports activities in middle childhood show improved behaviour and attentiveness in early adolescence, suggests a new Canadian study published in Preventative Medicine.
"Girls who do regular extracurricular sports between ages 6 and 10 show fewer symptoms of attention-deficit/hyperactivity disorder (ADHD) at age 12, compared to girls who seldom do," said Linda Pagani, a professor at Université de Montréal's School of Psychoeducation.
As the globe warms, the atmosphere is becoming more unstable, but the oceans are becoming more stable, according to an international team of climate scientists, who say that the increase in stability is greater than predicted and a stable ocean will absorb less carbon and be less productive.
New research has identified a mechanism by which low levels of insecticides such as, the neonicotinoid Imidacloprid, could harm the nervous, metabolic and immune system of insects, including those that are not pests, such as our leading pollinators, bees.
Osaka, Japan - Human cells need to work like well-oiled machines to keep our bodies running as they should. Waste products such as misfolded proteins, damaged cellular components, and carbohydrates get in the way and must be quickly disposed of. Dealing with this cellular "trash" are spherical, membrane-bound organelles called lysosomes filled with a mixture of potent enzymes. In a process called autophagy, waste products are contained within a double-membraned vesicle, called an autophagosome, that fuses with a lysosome.
