Study develops framework for forecasting contribution of snowpack to flood risk during winter storms
A new study provides a framework for a snowpack decision support tool that could help water managers prepare for potential flooding during rain-on-snow events, using hourly data from existing snow monitoring stations.
Experiments measure freezing point of extraterrestrial oceans to aid search for life
A planetary scientist worked with engineers to measure the physical limits for a liquid when salty water is at very high pressure. The results suggest where to look for extraterrestrial life in the ice-covered oceans of Jupiter’s moon Europa and Saturn…
Physicists develop ideal testing conditions of solar cells for space applications
Researchers have described the optimal conditions for testing perovskite solar cells for space.
Fluorescent probe for bad cooking oil in the portable platform
A research team develops a fluorescent molecular sensor for detecting bad cooking oils. The novel technology enables anyone to easily measure the cooked time for all kinds of cooking oils.
B12 deficiency harms young children’s development, and the food relief we provide isn’t good enough
Vitamin B12 deficiency in infants leads to poor motor development and anemia, according to a new study . B12 deficiency is an enormous, yet overlooked problem, and the food relief currently suppied is not helping. According to the researchers, the prob…
In poplars, two plant hormones boost each other in defense against pathogenic fungi
In contrast to previous assumptions, the defense hormones salicylic acid and jasmonic acid do not always suppress each other in regulating plant chemical defenses against pests and pathogens. In trees, the interplay of both hormones can actually increa…
Student satisfaction in flipped classroom is built on guidance, pedagogy, and a safe atmosphere
Students are satisfied with flipped classroom when they have systematic guidance on the teaching approach in use, comprehensive understanding of both the content being taught and the discipline more generally, and a safe learning atmosphere conducive t…
Dual membrane offers hope for long-term energy storage
A new approach to battery design could provide the key to low-cost, long-term energy storage, according to researchers.
How the black rat colonized Europe in the Roman and Medieval periods
New ancient DNA analysis has shed light on how the black rat, blamed for spreading Black Death, dispersed across Europe — revealing that the rodent colonized the continent on two occasions in the Roman and Medieval periods. By analyzing DNA from ancie…
Beetle iridescence a deceptive form of warning coloration
A new study published today in Animal Behaviour shows for the first time that brilliant iridescence and gloss found in some animals can have a protective function by working as a form of deceptive warning coloration, and that it is the key feature of i…
Proposed spacecraft navigation uses x-rays from dead stars
The remnants of a collapsed neutron star, called a pulsar, are magnetically charged and spinning anywhere from one rotation per second to hundreds of rotations per second. These celestial bodies, each 12 to 15 miles in diameter, generate light in the x…
Study preserves memory in mice, offering promising new basis for active immunization against Alzheimer’s disease
During experiments in animal models, researchers have discovered a possible new approach to immunization against Alzheimer’s disease. Their method uses a recombinant methionine (Met)-rich protein derived from corn that was then oxidized in vitro to pro…
Brain networks can play role in weight-loss success
When it comes to weight loss, the old adage it’s all in your head may be true. Scientists have shown that two specific networks in the brain can strongly influence how successful a person will be when trying to lose weight.
For stroke survivors, modified cardiac rehabilitation can reduce the chances of death by 76%
Survivors of serious stroke can reduce their chances of dying within the year by 76% if they complete a modified cardiac rehabilitation program that includes medically supervised exercise, prescribed therapy, and physician follow-up, according to new r…
Dog coronavirus jumps to humans, with a protein shift
Researchers have identified a shift that occurs in canine coronavirus that may provide clues as to how it transmits from animals to humans.
What happens when traits jump between branches of the tree of life
We all must play the game of life with the cards we’re dealt, so the common aphorism goes. In biology, this means organisms must compete through natural selection with the genes and anatomy they were born with. But the saying is a lie. Okay, it’s not e…
Lost value of landfilled plastic in US
With mountains of plastic waste piling up in landfills and scientists estimating that there will be more plastics by weight than fish in the ocean by 2050, the growing environmental challenge presented to the world by plastics is well understood. What …
Finding your car in a parking lot relies on this newly discovered brain circuit
When exploring a new environment, mice make use of a unique long-distance connection in the brain that prompts them to pay attention to the most salient features of the environment, according to new research. The link, originating in the prefrontal cor…
Combination of drugs for obesity and Type 2 diabetes may be more effective than a single therapy
Researchers have identified new drug combinations to treat people with obesity and Type 2 diabetes. The goal is to develop personalized prescriptions that are more effective than single drugs and that can potentially replace more invasive treatments su…
