An anesthetic may affect tau spread in the brain to promote Alzheimer"s disease pathology
Previous research has suggested that an inhaled anesthetic called sevoflurane may promote the brain changes of Alzheimer's disease. A new study in cells and mice reveals that sevoflurane causes the Alzheimer's-related protein tau to leave neurons and.....»»
Scientists decode brain mechanisms of stopping in Drosophila
Ever wish you could stop that fruit fly on your kitchen counter in its tracks? Scientists at Max Planck Florida Institute for Neuroscience have created flies that halt under red light. In doing so, they discovered the precise neural mechanisms involv.....»»
First map of every neuron in an adult brain has been produced for a fruit fly
The first wiring diagram of every neuron in an adult brain and the 50 million connections between them has been produced for a fruit fly......»»
Study finds Mexican free-tailed bats unlikely to spread Chagas disease in Texas
Bats are widely known around the world for their role in the spread of a number of zoonotic diseases—illnesses that can spread between humans and animals......»»
Smoke from megafires puts orchard trees at risk: Effects last months, reducing nut yields
Long-term smoke exposure from massive wildfires lowers the energy reserves of orchard trees and can cut their nut production by half, researchers at the University of California, Davis, found. The smoke can affect trees for months after a megafire, d.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»

Online misinformation most likely to be believed by ideological extremists, study shows
Political observers have been troubled by the rise of online misinformation—a concern that has grown as we approach Election Day. However, while the spread of fake news may pose threats, a new study finds that its influence is not universal. Rather.....»»
Engineers investigate another malfunction on SpaceX’s Falcon 9 rocket
SpaceX probably won't be grounded for long, but this could affect the launch of Europa Clipper. Enlarge / The Merlin vacuum engine on SpaceX's Falcon 9 rocket fired for six minutes to place the Crew-9 mission into low-Earth orbit.....»»
China calls for satellite broadband to face real-time censorship

Molecular computing method uses metal ions to mimic complex mathematical functions
Researchers at the University of Twente have developed a new method that allows them to precisely control chemical reactions using metal ions. This marks an important step toward computers that function like the human brain. They recently published t.....»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»
How climate change affects deer—experts draw findings from 20 years of research
Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species.....»»
Apple patent describes using AirPods to detect heart disease, likely next year
9to5Mac recently discovered evidence in iOS 18 that Apple is testing using future AirPods models to measure heartbeat, with our sources indicating that the feature will be implemented in both AirPods Pro 3 and the next generation of Powerbeats Pro......»»
New hazard maps may predict rust disease in loblolly pine trees
New models developed by University of Georgia researchers may help guide the fight against rust disease, according to a new study. The paper is published in the journal Forest Ecology and Management......»»
Study explores what families fight about: Communication, moods, and chores
Conflict in families can negatively affect individuals' well-being and relationships. But what exactly do families today fight about, and is conflict in the home generally more severe between couples or between parents and children?.....»»
Spread of deadly EEE virus explodes 5-fold in New York; one death reported
Normally only 2 or 3 counties have EEE-positive mosquitoes; there's 15 this year. Enlarge / An entomologist for the Louisville Metro Department of Public Health and Wellness in a swampland area on August 25, 2021 in Louisville, K.....»»
Study finds extreme temperatures increase mortality rates, with heat disproportionately affecting minorities
A new study examined how extreme temperatures in the United States significantly affect mortality among different racial groups and found that both cold and hot days increase mortality rates, with the latter disproportionately affecting underrepresen.....»»
Heat, animal illness and erosion risks to affect NZ agriculture with changing climate
Scientists at Manaaki Whenua—Landcare Research have worked closely with researchers from NIWA, AgResearch and Plant & Food Research to model the likely risks of a warming climate across different agricultural sectors in New Zealand. The study is pu.....»»
Rising waters, waning forests: Scientists are using tree rings to study how rising sea levels affect coastal forests
Sunlight filters through the canopy of pines, holly, sweet gum, and red maple while bird calls echo in the distance. These coastal forests may seem like others in the Mid-Atlantic, but a hidden challenge looms. Standing tall next to their salt marsh.....»»
Murine study suggests cosmic radiation in outer space may affect long-term cognition
