Medical Xpress / Taking a closer look at immune 'memory' could spur progress in the fight against lethal illnesses
The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells to target specific pathogens. ...
Phys.org / Math model reveals how life may have switched on from Earth's primordial soup
Isolating the first spark of life on Earth is a matter of biology, geology, and chemistry—but it's also an amazing math problem. At least, that's how Varun Varanasi viewed it when he was a Yale undergraduate. The question, ...
Medical Xpress / GLP-1 medicine improves liver health independent of weight loss, study finds
Researchers at Toronto's Sinai Health have found that semaglutide—the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1—acts directly on a subset of liver cells to improve organ function and ...
Medical Xpress / Study reveals how dreams affect our emotions in day-to-day life
There are a few reasons why we might dream, say neuroscientists. Even dreams that are scary may serve a purpose: One prevalent idea is that fear in dreams could help people deal with fear in waking life, much like exposure ...
Medical Xpress / Low-frequency wireless sensor tracks artery stiffening in real time with less interference
Wireless sensors used in wearable smart devices and medical equipment must be capable of detecting minute changes while maintaining high operational stability. However, existing technologies often utilize excessively high ...
Phys.org / Video shows that sunbirds suck, while hummingbirds don't
Two unrelated groups of nectar eaters, hummingbirds and sunbirds, have evolved different techniques to slurp the sweet liquid from flowers. The tongue suctioning employed by sunbirds is unique among vertebrates, according ...
Phys.org / Deep learning turns weather satellite thermal imagery into hourly ocean current maps
Scientists have developed a new method to measure ocean surface currents over large areas in greater detail than ever before. Called GOFLOW (Geostationary Ocean Flow), the approach applies deep learning to thermal images ...
Medical Xpress / Study finds no link between medical gender reassignment and improved mental health among young people
An extensive register-based study conducted in Finland has found an increase in severe mental health problems among some adolescents and young adults who have undergone medical gender reassignment (GR). According to the research, ...
Phys.org / Discarded wood helps produce hydrogen peroxide with more than 95% selectivity
Hydrogen peroxide, a versatile chemical used in a wide range of applications—from medical disinfectants to semiconductor manufacturing and water treatment—is an essential substance with global annual production exceeding ...
Phys.org / Integration of two genes: A valuable strategy for developing virus-resistant tomatoes
Tomato yellow leaf curl disease (TYLCD), caused by begomoviruses, is a global problem in tomato production, affecting yield. While introduction of resistance genes is one of the strategies to control TYLCD, introduction of ...
Phys.org / Quantum sensors get a precision boost as 2D defects reveal their hidden timing
A key factor for the performance of sensors is the speed at which the system returns to its initial state after a disturbance or measurement, similar to the taring of a balance. In the quantum sensor under investigation, ...
Phys.org / Using atomic nuclei could allow scientists to read time more precisely than ever
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.
