Hand washing fabrics reduces microplastic release compared with machine washing

From tiny plankton to massive whales, microplastics have been found throughout the ocean food chain. One major source of this pollution are fibers shed while laundering synthetic fabrics. Although many studies show microfibers are released during machine washing, it’s been less clear how hand washing contributes. Now, researchers reporting in…

Fossils reveal dinosaurs of prehistoric Patagonia

A study led by The University of Texas at Austin is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods — a dinosaur group that includes both modern birds and…

Discovery of cross-species signaling pathway unlocks mysteries around parasite immunity and development: Ticks recognize a cytokine from infected mammalian blood, triggering a defense against Lyme disease-causing bacteria

Research led by a University of Maryland team has identified the first inter-species signaling pathway between an arthropod parasite and host, where molecules in the blood of a host animal triggers the immunity and development of a parasite. The study showed that when ticks feed on the blood of mice…

Live updates: Garland makes statement on Biden classified documents

Attorney General Merrick Garland delivers his statement on Thursday. (Olivier Douliery/AFP/Getty Images) Attorney General Merrick Garland detailed the timeline of the investigation into President Joe Biden’s potential mishandling of classified documents. Here’s what he said: Nov. 4, 2022: The National Archives Office of Inspector General contacted a prosecutor at the Department of Justice…

Using machine learning to help monitor climate-induced hazards: Study finds way to track hurricane landfalls, other hazards using satellite data

Combining satellite technology with machine learning may allow scientists to better track and prepare for climate-induced natural hazards, according to research presented last month at the annual meeting of the American Geophysical Union. Over the last few decades, rising global temperatures have caused many natural phenomena like hurricanes, snowstorms, floods…

How did the Butterfly Nebula get its wings? It’s complicated

Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel — becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling patterns as it is blown gently into the…

Scientists identify gene target to boost effectiveness of cancer immunotherapy

Immune checkpoint inhibitors are important medications that boost the immune system’s response against various cancers, but some patients’ cancer cells are unaffected by the drugs or develop resistance during treatment. Researchers led by a team at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham, and the Broad…

Rx for prolonged sitting: A five-minute stroll every half hour

Mounting evidence suggests that prolonged sitting — a staple of modern-day life — is hazardous to your health, even if you exercise regularly. Based on these findings, doctors advise all adults to sit less and move more. But how often do we need to get up from our chairs? And…

Novel design helps develop powerful microbatteries

Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable medical devices. University of Illinois Urbana-Champaign researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by…

Birth date: January 28, 1955 Birth place: Paris, France Birth name: Nicolas Paul Stéphane Sarkozy de Nagy-Bocsa Father: Pal Sarkozy de Nagy Bocsa Mother: Andrée (Mallah) Sarkozy de Nagy Bocsa Marriages: Carla Bruni (2008-present); Cécilia…

Zach Johnson isn’t discounting Tiger Woods for the Ryder Cup | CNN

CNN  —  Tiger Woods could form part of the US Ryder Cup team – or at least, Zach Johnson isn’t ruling it out. Ahead of the Sony Open in Hawaii, US captain Johnson said he wouldn’t discount selecting Woods to compete in the tournament if the 47-year-old didn’t qualify for…

Turning abandoned mines into batteries

A novel technique called Underground Gravity Energy Storage turns decommissioned mines into long-term energy storage solutions, thereby supporting the sustainable energy transition. Renewable energy sources are central to the energy transition toward a more sustainable future. However, as sources like sunshine and wind are inherently variable and inconsistent, finding ways…

Enzyme ‘atlas’ helps researchers decipher cellular pathways: Biologists have mapped out more than 300 protein kinases and their targets, which they hope could yield new leads for cancer drugs

One of the most important classes of human enzymes are protein kinases — signaling molecules that regulate nearly all cellular activities, including growth, cell division, and metabolism. Dysfunction in these cellular pathways can lead to a variety of diseases, particularly cancer. Identifying the protein kinases involved in cellular dysfunction and…

Fish-hunting and eating behaviors confirmed in Japanese macaques

Upon further studying using film and sensor cameras, 14 documented cases show these macaques are fishing for sustenance, with an additional six cases of fish capture and feeding being highly likely. These cases were documented amongst at least three different groups of macaques and seem to occur independent of the…

Dolphins ‘shout’ over loud underwater noise to complete a cooperative task

Dolphins are social, intelligent animals who rely on whistles and echolocation to hunt and reproduce. This means that noise generated from human activity such as drilling and shipping has the potential to negatively impact the health of wild dolphin populations. A study in the journal Current Biology published on January…

How sex differences influence lung injury in mice

More than 2,500 genes exhibit significant sex differences in expression in mouse alveolar type II cells (AT2s), important for keeping the lungs functioning, potentially explaining sex biases in the prevalence and severity of lung diseases. In particular, very high numbers of X-linked genes escape transcriptional silencing in lung alveolar type…

Mature ‘lab grown’ neurons hold promise for neurodegenerative disease: Researchers advanced the age of human neurons beyond what was previously possible

Northwestern University-led researchers have created the first highly mature neurons from human induced pluripotent stem cells (iPSCs), a feat that opens new opportunities for medical research and potential transplantation therapies for neurodegenerative diseases and traumatic injuries. Although previous researchers have differentiated stem cells to become neurons, those neurons were functionally…
