A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce. Read more ›

Simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center (TACC) are helping scientists engineer solutions to overheating of grid transformers -- a critical component of the electric grid. Read more ›

Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the...

In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers have shown how two old methods can be combined to provide greater flexibility. Read more ›

Some of the world's deadliest bacteria seek out and feed on human blood, a newly-discovered phenomenon researchers are calling 'bacterial vampirism.' Researchers have found the bacteria are attracted to the liquid part of blood, or serum, which contains nutrients the bacteria can use as food. One of the chemicals the bacteria seemed particularly drawn to was serine, an amino acid found in human blood that is also a common ingredient... Read more ›

New research explains why metastatic uveal melanoma is resistant to conventional immunotherapies and how adoptive therapy, which involves growing a patient's T cells outside the body before reinfusing them, can successfully treat this rare and aggressive cancer. Read more ›

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show... Read more ›

Patients with suspected inflammatory bowel disease (IBD) could benefit from better testing protocols that would reduce the need and lengthy wait for potentially unnecessary colonoscopies, a new study has found. Read more ›

For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals.

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun. Read more ›

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing filament. Furthermore, the scientists elucidated the reasons for the different speeds at which the different formins promote this process. Read more ›

According to a recent study, either healthier or unhealthier health behaviors cluster among individuals. These health behavior patterns remain relatively stable in middle adulthood and are predicted by several sociodemographic and personality characteristics. Read more ›

An international research team has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be 'switched' on and off, which has potential for developing tiny, energy-efficient transistors -- like the light switch in your house but at a nanoscale.

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have reduced fertility and are unsuitable for breeding resistant lines. The reason is that the pollen tube in these plants grows incorrectly, which keeps fertilization from taking place. Pollen tube growth is mainly controlled by two genes that could be useful in crop...

According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago). Read more ›
