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 / 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 / New research on cellular redox reactions sheds light on the path of neurodegenerative diseases
The mechanics of the onset of cancer or neurodegenerative disorders like Alzheimer's disease or ALS remain a mystery. Scientists associate these diseases with an increase in unstable molecules called reactive oxygen species ...
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 / 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 / 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 / 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 ...
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, ...
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 / Plants use a protein-tagging complex to control stress survival, study finds
A specific cellular mechanism regulates the protein balance of plants, thereby influencing how they respond to environmental stress. An international research team led by Dr. Markus Wirtz at the Center for Organismal Studies ...
Phys.org / Hidden damage in stony corals revealed using 3D imaging and AI
Florida's coral reefs are under siege. Since 2014, Stony Coral Tissue Loss Disease (SCTLD) has spread rapidly across the Florida Reef Tract and Caribbean, killing vast numbers of reef-building corals and leaving behind dead ...
