Published Scientists generate first single-cell 'atlas' of the primate brain to help explore links between molecules, cells, brain function and disease
(via sciencedaily.com) Original source As part of the effort to better understand the evolution of the brains in people and animals, a research team has generated the world's largest primate brain-wide atlas.
Published Coffee and cocoa plants at risk from pollinator loss
(via sciencedaily.com) Original source Tropical crops such as coffee, cocoa, watermelon and mango may be at risk due to the loss of insect pollinators, finds a new study.
Published Scientists unveil detailed cell maps of the human brain and the nonhuman primate brain
(via sciencedaily.com) Original source A group of international scientists have mapped the genetic, cellular, and structural makeup of the human brain and the nonhuman primate brain. This understanding of brain structure allows for a deeper knowledge of the cellular basis of brain function and dysfunction, helping pave the way for a new generation of precision therapeutics for people with mental disorders and other disorders of the brain.
Published Engineered bacteria paint targets on tumors for cancer-killing T cells to see
(via sciencedaily.com) Original source Synthetic biologists report on a new approach to attacking tumors. They have engineered tumor-colonizing bacteria (probiotics) to produce synthetic targets in tumors that direct CAR-T cells to destroy the newly highlighted cancer cells.
Published Honey bees may inherit altruistic behavior from their mothers
(via sciencedaily.com) Original source True altruism is rare behavior in animals, but a new study has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from.
Published Win-win in muscle research: Faster results and fewer laboratory animals thanks to new method
(via sciencedaily.com) Original source To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.
Published Omega-3 discovery moves us closer to 'precision nutrition' for better health
(via sciencedaily.com) Original source Researchers have obtained new insights into how African-American and Hispanic-American people’s genes influence their ability to use Omega-3 and Omega-6 fatty acids for good health. The findings are an important step toward “precision nutrition” – where a diet tailored to exactly what our bodies need can help us live longer, healthier lives.
Published Using different flours for sourdough fosters different bacteria -- and flavors
(via sciencedaily.com) Original source A new study of the microbial ecosystem in sourdough finds that using different types of flour fosters distinct bacterial communities, and that these differences contribute to the variation of sourdough aromas and flavors.
Published Study clearly identifies nutrients as a driver of the Great Atlantic Sargassum Belt
(via sciencedaily.com) Original source Under normal conditions, the floating macroalgae Sargassum spp. provide habitat for hundreds of types of organisms. However, the Great Atlantic Sargassum Belt (GASB) that emerged in 2011 has since then caused unprecedented inundations of this brown seaweed on Caribbean coastlines, with harmful effects on ecosystems while posing challenges to regional economies and tourism, and concerns for respiratory and other human health issues.
Published An AI tool that can help forecast viral outbreaks
(via sciencedaily.com) Original source EVEscape predicts future viral mutations, new variants using evolutionary, biological information.
Published Fruit fly serenade: Neuroscientists decode their tiny mating song
(via sciencedaily.com) Original source An extremely supportive atmosphere for new ideas laid the foundation for an 'Aha moment' about a toggle-switch in the fruit fly brain. Do humans have one, too?
Published Doubling down on known protein families
(via sciencedaily.com) Original source A massive computational analysis of microbiome datasets has more than doubled the number of known protein families. This is the first time protein structures have been used to help characterize the vast array of microbial 'dark matter.'
Published Evolutionary secrets of 'Old Tom' and the killer whales of Eden revealed by genetic study
(via sciencedaily.com) Original source Evolutionary biologists have for the first time decoded the genetic lineage of a famous killer whale and a pod that once worked alongside whale hunters off the coast of Australia. In the Australian tradition of claiming New Zealand's celebrities as its own, Old Tom, the leader of a pod of killer whales that famously helped whalers hunt baleen whales in the 20th century, has ancestral links to modern-day killer whales in New Zealand, according to new DNA research. Old Tom also shared a common ancestor with killer whales from Australasia, the North Pacific, and North Atlantic Oceans, but is most similar to modern New Zealand killer whales. However, most of Tom's DNA code is not found in other killer whales globally suggesting that the killer whales of Eden may have become extinct locally.
Published Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats
(via sciencedaily.com) Original source Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
Published Death is only the beginning: Birds disperse eaten insects' eggs
(via sciencedaily.com) Original source Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.
Published How plant-derived nutrients can affect the gut and brain
(via sciencedaily.com) Original source Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists investigated this question in a study of overweight adults. Their findings suggest that dietary fiber can exert influence on both the composition of gut bacteria and the reward signals in the brain and associated food decision-making.
Published Wild pig populations in U.S. can be managed
(via sciencedaily.com) Original source Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
Published Predator-prey defense mechanisms unlock key to marine biofuel production
(via sciencedaily.com) Original source Researchers have unpicked the mechanism behind a marine feeding strategy that could provide a valuable renewable source of biofuel.
Published Race to find world's oldest mammal fossils led to mud-slinging
(via sciencedaily.com) Original source The hunt for the world’s most ancient mammals descended into academic warfare in the seventies, researchers have discovered.
Published Evidence from the remains of 1918 flu pandemic victims contradicts long-held belief that healthy young adults were particularly vulnerable
(via sciencedaily.com) Original source New analysis of the remains of victims of the 1918 influenza pandemic, which killed an estimated 50 million people worldwide, contradicts the widespread belief the flu disproportionately impacted healthy young adults.
