A team of scientists led by Caltech and Emory University has synthesized a highly complex natural molecule using a novel strategy that functionalizes normally nonreactive bonds, called carbon–hydrogen (C–H) bonds. The work demonstrates a new category of reactions that organic chemists can consider as they work to create natural products that could be used in pharmaceuticals or new materials, or to produce organic chemicals in more sustainable ways.   "This work moves the field forward by showing the power of C–H functionalization," says ...

LOGAN, UTAH, USA -- When a large mammal such as a deer or a moose is struck by a motor vehicle, the damage is usually dramatic. To reduce these unfortunate events, transportation officials have teamed with wildlife researchers to place warning signs, and to construct wildlife underpasses and overpasses, to mitigate mishaps along animal migration paths. In contrast, collisions with much smaller bees often go unnoticed or are perceived by motorists as simply an annoying splat on a windshield. The significance, Utah State University ...

Teams of mountaineering mice are helping advance understanding into how evolutionary adaptation to localized conditions can enable a single species to thrive across diverse environments. In a study led by Naim Bautista, a postdoctoral researcher in Jay Storz’s lab at the University of Nebraska–Lincoln, the team took highland deer mice and their lowland cousins on a simulated ascent to 6,000 meters. The “climb” ventured from sea level and the mice reached the simulated summit seven weeks later. Along the way, Bautista tracked how the mice responded to cold stress at progressively lower oxygen levels. “Deer ...

LOGAN, UTAH, USA – Any boomer, gen xer, millennial, gen zer or alpha who’s studied geology has likely gained foundational knowledge from Edwin Dinwiddie McKee’s landmark studies of the Grand Canyon’s sedimentary record – even if they don’t readily recognize McKee’s name. The legendary scientist, who lived from 1906-1984, studied and documented the stratigraphy and sedimentation of Colorado Plateau geology, especially the Grand Canyon’s Cambrian Tonto Group, for more than 50 years. His time-tested ...

There’s no cure for a fungal disease that could potentially wipe out much of global banana production. Widespread adoption of cement paths, disinfection stations, and production strategies could net 3-4 USD of benefits for each dollar invested in Colombia.  Hundreds of millions of dollars in banana exports from Colombia are at risk due to a fungal disease best known as Tropical Race 4 (TR4). First detected in Asia in the 1990s, the Fusarium fungus that causes the disease arrived in Colombia in 2019, completing its inevitable global spread to South America, the last major banana production continent that remained TR4-free. Researchers are confident ...

New research reveals for the first time how a major Antarctic ice shelf has been subjected to increased melting by warming ocean waters over the last four decades. Scientists from the University of East Anglia (UEA) say the study - the result of their autonomous Seaglider getting accidentally stuck underneath the Ross Ice Shelf - suggests this will likely only increase further as climate change drives continued ocean warming. The glider, named Marlin, was deployed in December 2022 into the Ross Sea from the edge of the sea ice. Carrying a range of sensors to collect data on ocean processes that are important for climate, it was programmed to travel northward into ...

Navigating the intersection of alcohol use and intimate partner violence amongst young couples is not an easy journey, and for bisexual+ couples, the road may be even more winding.   “No study has examined the extent to which alcohol use increases intimate personal violence among bisexual+ young adults or daily experiences unique to them. Our study will look at factors such as minority stressors that may lead to alcohol-related partner violence,” said Meagan Brem, director of the Research for Alcohol and Couple’s Health Lab at Virginia Tech. Alcohol use and intimate partner violence - defined as any action in a ...

Tool use isn’t unique to humans. Chimpanzees use sticks as tools. Dolphins, crows, and elephants are known for their tool-use abilities, too. Now a report in the Cell Press journal Current Biology on November 8, 2024, highlights elephants’ remarkable skill in using a hose as a flexible shower head. As an unexpected bonus, researchers say they also have evidence that a fellow elephant knows how to turn the water off, perhaps as a kind of “prank.” “Elephants are amazing with hoses,” says Michael Brecht ...

When people have an audience watching them, it can change their performance for better or worse. Now, researchers reporting in the Cell Press journal iScience on November 8 have found that chimpanzees’ performance on computer tasks is influenced by the number of people watching them. The findings suggest that this “audience effect” predates the development of reputation-based human societies, the researchers say. “It was very surprising to find that chimpanzees are affected in their task performance by ...

KEY TAKEAWAYS Researchers from Mass General Brigham are leveraging artificial intelligence to help identify the signs of long COVID, track how different symptoms manifest over time, and eliminate alternative explanations for patients’ symptoms. The new approach suggests that 22.8% of the population experience the symptoms of long COVID, a figure that may paint a more realistic picture of the pandemic’s long-term toll. Through analyzing a patient’s history over time, this new AI tool ...
