A powerful tool speeds success in achieving highly efficient thermoelectric materials
Thermoelectric materials could play an important role in the clean energy transition, as they can produce electricity from sources of heat that would otherwise go to waste. Researchers report a new approach to efficiently predict when thermoelectric ma…
Airborne technology brings new hope to map shallow aquifers in Earth’s most arid deserts
The new technique will map the top of the aquifer, called the ‘water table,’ spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft. According to the researchers, Desert-SEA will measure the variabilities in…
A new ‘rule of biology’ may have come to light, expanding insight into evolution and aging
A molecular biologist may have found a new ‘rule of biology.’ The rule challenges long-held notions that most living organisms prefer stability over instability because stability requires less energy and fewer resources.
Large language models can’t effectively recognize users’ motivation, but can support behavior change for those ready to act
Large language model-based chatbots can’t effectively recognize users’ motivation when they are hesitant about making healthy behavior changes, but they can support those who are committed to take action, say researchers.
Normothermic perfusion system extends life of organs waiting for transplant
In the United States, about 30-40% of donor hearts aren’t considered for transplant due to inadequate function in the donor. This leads to a drop in the number of donated hearts that are available to be matched with someone who needs a heart transplant.
High-frequency electrical ‘noise’ may result in congenital night blindness
In what they believe is a solution to a 30-year biological mystery, neuroscientists say they have used genetically engineered mice to address how one mutation in the gene for the light-sensing protein rhodopsin results in congenital stationary night bl…
Imaging fibrous structure abnormalities of the white of the eye in myopathic patients
Abnormalities in the shape of the sclera, the white of the eye, can cause various complications and lead to blindness. However, techniques to observe the sclera in detail, such as its fibrous structure, are lacking. Now, researchers have used polarizat…
Different brain structures in females lead to more severe cognitive deficits after concussion than males
Important brain structures that are key for signaling in the brain are narrower and less dense in females, and more likely to be damaged by brain injuries, such as concussion. Long-term cognitive deficits occur when the signals between brain structures…
B cells drive responses of other immune cells, and can be modified to prevent Multiple Sclerosis symptoms
B cells can control responses of myeloid cells through the release of particular cytokines (small proteins that control the growth and activity of cells in the immune system), challenging the prevailing view that T cells are the principle orchestrators…
