Phys.org / A targeted 'off switch' in a plant's egg cell speeds up the breeding process
An international research team led by the IPK Leibniz Institute has succeeded in generating haploids in the model plant Arabidopsis thaliana very efficiently. This process involves degrading a specific protein in the centromere. ...
Phys.org / Even the most remote ocean is contaminated with zinc from human sources, research reveals
The vast, deserted South Pacific is considered unspoiled nature. But this ocean is not as unspoiled as we would like to think. A new study by a group of researchers from ETH Zurich and the GEOMAR Helmholtz Center for Ocean ...
Phys.org / Space junk falls to Earth faster when sunspots peak, reshaping satellite collision forecasts
Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun's activity across ...
Medical Xpress / Bullying and politics fuel suicide risk for LGBTQ+ teens and young adults, survey finds
More than a third of LGBTQ+ young people have seriously considered suicide in the past year, driven by bullying from both peers and politicians, a new survey has found.
Science X / Huge tsunami in popular area for Alaskan cruises provides lessons in steep, mountainous terrain
When part of a mountain in southeast Alaska slid into the ocean last summer, it triggered the second highest tsunami ever recorded. That tsunami ran 481 meters—one-and-a-half times the height of the Eiffel Tower—up the wall ...
Medical Xpress / New GlyT2 blocker relieves chronic neuropathic pain without major side effects
Chronic neuropathic pain remains one of the most challenging conditions to treat, with current therapies offering limited benefit and being over-reliant on opioids. Researchers at Rensselaer Polytechnic Institute (RPI), along ...
Medical Xpress / How the senses intertwine to help store new speech patterns
We don't usually realize it, but every word we speak depends on a series of complex brain processes working behind the scenes. One important part of this is speech motor learning, the brain's ability to learn and remember ...
Medical Xpress / Finger-prick blood test may spot active tuberculosis early and predict who develops disease
Household contacts of people with tuberculosis (TB) have a high risk of getting TB themselves, at around 2%. It is currently difficult to detect TB in its early stages, or predict who will go on to have TB, and therefore ...
Tech Xplore / Water-splitting catalyst unlocks cheaper hydrogen at significantly lower temperatures
University of Birmingham research published today has shown a new low-temperature method for producing hydrogen that is suitable for both centralized hydrogen production, and also local generation using waste heat from large-scale ...
Tech Xplore / Chemical hardness engineering boosts perovskite tandem efficiency to 30.3%
All-perovskite tandem solar cells are promising candidates for next-generation photovoltaics, as they harvest sunlight more efficiently than single-junction devices and can be fabricated through low-temperature solution processing. ...
Phys.org / Carbon-free ferrocene alternative opens up new possibilities for future materials
About 75 years ago, scientists accidentally synthesized a compound called ferrocene in which the iron (Fe) atom is sandwiched between two C5H5 rings—(C5H5)Fe(C5H5). This compound opened up a new era in transition metal chemistry, ...
Medical Xpress / Oral small-molecule GLP-1 drugs penetrate deep into the brain to suppress cravings
A study has found that an emerging class of GLP-1 weight-loss drugs suppresses eating for pleasure, or hedonic feeding, in mice by modulating a reward circuit deep within the brain. This newly charted pathway—separate from ...
