Credit: PixabayThe bacteria in your mouth affect more than just your teeth and gums—they may also play a role in brain function. A study of 55 people with mild cognitive impairment (MCI) found that those with higher levels of Neisseria bacteria performed better on tests of working memory, executive function, and visual attention. Even...
Credit: PixabayWhen you sleep and dream, your brain may undergo a "rinse cycle," clearing out toxic by-products to prepare for the next day. Researchers from the University of Copenhagen have now mapped the flow of neurotransmitters, blood, and cerebrospinal fluid in mice, uncovering how this process works—and revealing that common sleep drugs like Ambien...
Credit: PixabayResearchers have identified how a specific protein, DUSP6, influences the growth and spread of colon cancer, offering new insights into why this type of cancer can be aggressive in certain patients. This discovery not only advances our understanding of colorectal cancer (CRC) but also reveals a promising treatment target.Cancer cells rely on various...
Credit: PixabaySalmonella is commonly associated with contaminated food or water, but a new study reveals pet dogs might also be significant carriers of this bacteria. Researchers from Pennsylvania State University (PSU) found that dogs, even when asymptomatic, can transmit nontyphoidal, antibiotic-resistant Salmonella to humans. This discovery highlights the close relationship between humans and their...
"Flying over aurora; intensely green." (Don Pettit/X)A breathtaking video captured from the International Space Station reveals an aurora from above, shimmering with the distinctive green light that has fascinated humanity for centuries.On January 6, NASA astronaut Don Pettit shared this extraordinary footage from his vantage point in orbit, showcasing the "intensely green" ribbons of light...
Researchers in Sweden have uncovered a potential link between gut bacteria and the formation of heart artery plaques in a large-scale study, suggesting that oral bacteria like Streptococcus could play a key role in heart disease.A recent study linked gut bacteria to heart health by analyzing data from 8,973 Swedish participants aged 50 to...
Credit: PixabayChirality, a key property in biological, chemical, and physical processes, plays a vital role in enabling unique interactions with polarized light and chiral molecules. As a result, chiral solids are highly valued for applications in catalysis, sensing, and optical technologies. However, chirality in crystals has traditionally remained fixed during their formation, as altering...
Using a clever device consisting of multiple thin layers, the physicists manage to output the edges of incoming images. Credit: UvAResearchers at the University of Amsterdam’s Institute of Physics, led by Jorik van de Groep, have introduced a groundbreaking method for edge detection that combines exceptional speed with minimal energy use. Their work, published...
Credit: PixabayHot Jupiters, once believed to orbit their stars alone, were thought to consume or eject nearby planets during their inward migration. However, recent findings have challenged this notion. A study from the University of Geneva (UNIGE), in collaboration with NCCR PlanetS, the Universities of Bern (UNIBE) and Zurich (UZH), and international institutions, uncovers...
Credit: PixabayA recent University of Bristol study, published in Nature Communications, reveals the rapid shrinkage of glaciers in Svalbard, Norway, over the past 40 years. The study shows that 91% of glaciers have significantly retreated, losing over 800 square kilometers of ice since 1985. Moreover, 62% now experience seasonal calving cycles due to rising...
