Published Atlas of proteins reveals inner workings of cells
(via sciencedaily.com) Original source Researchers discover how proteins behave inside cells using AI, which has the potential to guide drug design.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Big gain in battle against harmful bacteria
(via sciencedaily.com) Original source An unexpected find has enabled important progress to be made in the battle against harmful bacteria.
Published Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine
(via sciencedaily.com) Original source A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
Published Researchers listen to the hearts of bats in flight
(via sciencedaily.com) Original source Unique recordings show that bats can ramp up heart rate from 6 to 900 b.p.m within minutes.
Published New one-step method to make multiple edits to a cell's genome
(via sciencedaily.com) Original source A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com) Original source Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Cracking open a tasty menu for captive marsupials to sink their teeth into
(via sciencedaily.com) Original source From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published New bio-based tool quickly detects concerning coronavirus variants
(via sciencedaily.com) Original source Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
Published Brain size riddle solved as humans exceed evolution trend
(via sciencedaily.com) Original source The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed.
Published GeneMAP discovery platform will help define functions for 'orphan' metabolic proteins
(via sciencedaily.com) Original source Researchers have developed a discovery platform to probe the function of genes involved in metabolism -- the sum of all life-sustaining chemical reactions. The investigators used the new platform, called GeneMAP (Gene-Metabolite Association Prediction), to identify a gene necessary for mitochondrial choline transport.
Published Never-before-seen view of gene transcription captured
(via sciencedaily.com) Original source New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.
Published Do genes-in-pieces code for proteins that fold in pieces?
(via sciencedaily.com) Original source A new study offers new insights into the evolution of foldable proteins.
Published Researchers uncover key mechanisms in chromosome structure development
(via sciencedaily.com) Original source Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle.
Published Blue and great tits deploy surprisingly powerful memories to find food
(via sciencedaily.com) Original source Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs
(via sciencedaily.com) Original source Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published A new breakthrough in understanding regeneration in a marine worm
(via sciencedaily.com) Original source The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.
Published Spotted apex predator being pressured by spotted pack hunters -- and it's our fault
(via sciencedaily.com) Original source Leopards, who are already in decline, can't keep up with hyenas when people are around. As we humans move into the their territories more and more, we are helping to disturb and unbalance ecosystems. This has been shown in a new study where researchers used camera traps to observe both large carnivore species.
