Smallest-Ever Human-Made Flying Structure Is a Winged Microchip, Scientists Say
An anonymous reader quotes a report from NPR: It's neither a bird nor a plane, but a winged microchip as small as a grain of sand that can be carried by the wind as it monitors such things as pollution levels or the spread of airborne diseases. The t.....»»
Researchers decipher how an enzyme modifies the genetic material in the cell nucleus
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determin.....»»
Granting legal "personhood" to nature is a growing movement: Can it stem biodiversity loss?
Biodiversity is declining at rates unprecedented in human history. This suggests the ways we currently use to manage our natural environment are failing......»»
Scientists discover safer alternative for an explosive reaction used for more than 100 years
The chemical industry has been using a reaction with explosive chemicals for more than 100 years—now Mülheim scientists have discovered a safer alternative. The Ritter Group of the Max Planck Institut für Kohlenforschung in Mülheim/Ruhr has publ.....»»
Gigantic Jurassic raptor footprints unearthed in China

NASA astronauts arrive for Boeing"s first human spaceflight
The two NASA astronauts assigned to Boeing's first human spaceflight arrived at their launch site Thursday, just over a week before their scheduled liftoff......»»
Deer are expanding north, and that"s not good for caribou: Scientists evaluate the reasons why
As the climate changes, animals are doing what they can to adapt. Researchers from UBC Okanagan—which includes partners from Biodiversity Pathways' Wildlife Science Center, the Alberta Biodiversity Monitoring Institute, the University of Alberta, a.....»»
Escape the vapes: Scientists call for global shift to curb consumer use of disposable technologies
Scientists have called for a concerted global effort to stem the tide of disposable electronic technologies—such as vapes—contributing to international waste accumulation and environmental degradation......»»
Yeast study offers possible answer to why some species are generalists and others specialists
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolu.....»»
A shortcut for drug discovery: Novel method predicts on a large scale how small molecules interact with proteins
For most human proteins, there are no small molecules known to bind them chemically (so-called "ligands"). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel.....»»
Scientists say voluntary corporate emissions targets not enough to create real climate action
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper......»»
How much trust do people have in different types of scientists?
Understanding why some people trust some scientists more than others is a key factor in solving social problems with science. But little was known about the trust levels across the diverse range of scientific fields and perspectives......»»
Study demonstrates efficacy of web programming course for incarcerated individuals
Several years ago, a team of scientists from MIT and the University of Massachusetts at Lowell designed and deployed a first-of-its-kind web programming course for incarcerated individuals across multiple correctional facilities. The program, Brave B.....»»
Scientists use "leaf glow" to understand changing climate
New University of Minnesota research suggests "leaf glow" provides vital information on vegetation dynamics in Arctic and boreal ecosystems like Minnesota's forests and wetlands, which are among the fastest warming in the world. Using remote sensing.....»»
Did climate chaos cultivate or constrain 2023"s greenery?
In the ongoing quest to track the progression of climate change, scientists frequently examine the state of our planet's vegetation—forests, grasslands, agricultural lands, and beyond......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
Solar geoengineering to cool the planet: Is it worth the risks?
When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists and institutions are.....»»
Study says it"s likely a warmer world made deadly Dubai downpours heavier
Circumstantial evidence points to climate change as worsening the deadly deluge that just flooded Dubai and other parts of the Persian Gulf, but scientists didn't discover the definitive fingerprints of greenhouse gas-triggered warming they have seen.....»»
Advanced cell atlas opens new doors in biomedical research
Researchers at Karolinska Institutet have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about huma.....»»
