Laser technology called lidar is helping archaeologists complete years of fieldwork sometimes in the span of a single afternoon Archaeology is facing a time crunch. Thousands of years of human history risk imminent erasure, from tiny hamlets to entire cities – temples, walls and roads under grave threat of destruction . Urban sprawl and industrial agriculture are but two culprits, smothering anci

Climate policies are typically designed to reduce greenhouse gas emissions that result from human activities and drive climate change. The largest source of these emissions is the combustion of fossil fuels, which increases atmospheric concentrations of ozone, fine particulate matter (PM2.5) and other air pollutants that pose public health risks.

Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus's heat flow mechanism has been a mystery. A study that uses three-decade-old data from NASA's Magellan mission has taken a new look at how Venus cools and found that thin regions of the planet's

Aerosols transported to the upper troposphere/lower stratosphere (UTLS) region potentially reduce average global surface temperatures and alter atmospheric circulation.

Scientists have released one of the most precise measurements ever made of how matter is distributed across the universe today. When the universe began, matter was flung outward and gradually formed the planets, stars, and galaxies that we know and love today. By carefully assembling a map of that matter, scientists can try to understand the forces that shaped the evolution of the universe. Among

Researchers show that while strong distractions may automatically capture our attention, the trained brain can rapidly suppress such distractions to help us efficiently reach our goals.

An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can't. The research could lead to better air purifiers, particularly in regions of the world that suffer from very poor air quality. The more environmentally friendly air filter was able to simultaneously capture 99.5

The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found—to their surprise– that smaller and larger theropod dinosaurs like these didn't necessarily get that way merely by growing slower or faster.

Several studies have predicted that the water splitting reaction could be catalyzed by certain groups of 2D materials—each measuring just a few atoms thick. One particularly promising group are named 2D Janus materials, whose two sides each feature a different molecular composition.

Granular materials contain large numbers of small, discrete particles, which collectively behave like uniform media. Their thermal conductivity is crucial to understanding their overall behavior—but so far, researchers haven't considered how this value is affected by the surface roughness of their constituent particles.

UK environment secretary Thérèse Coffey has demanded that water companies share plans for how they will reduce sewage discharges into rivers. They could start by coming clean on how much sewage is being dumped. If we don't know how much sewage is actually being released—for at least the worst offending locations—we won't be able to measure environmental and industry improvement with any confidence

For most of human history, the stars blazed in an otherwise dark night sky. But starting around the Industrial Revolution, as artificial light increasingly lit cities and towns at night, the stars began to disappear.

Geologists doing fieldwork in southeastern Utah's Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancient carbon-cycle phenomenon, known as the 'Weissert Event' was driven by large, sustained volcanic eruptions in the Southern Hemisphere that greatly

Astronomers have discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings challenge long-held ideas about planet formation.

On average, 39 percent of time currently spent on unpaid domestic work could be automated within the next decade, suggest AI experts.

Blue foods — those that come from the ocean or freshwater environments — have tremendous potential to help address several global challenges. With careful implementation of policies that leverage these foods, nations could get a boost on efforts to reduce nutritional deficits, lower disease risk, decrease greenhouse gas emissions and ensure resilience in the face of climate change.

First of all, I'd like to preface that this is a discussion about the company YouTube, not the application. With that out of the way, Suzan has always been the CEO of YouTube, while its current CEO Neal Mohan functioned as the chief product officer. He was a big advocate of NFTs and that grinded a lot of users' gears. Thankfully, Suzan shot that decision down and the idea never came to fruition.

Abstract Myelodysplastic syndrome (MDS) is a clonal malignancy arising in hematopoietic stem cells (HSCs). The mechanisms of MDS initiation in HSCs are still poorly understood. The phosphatidylinositol 3-kinase (PI3K)/AKT pathway is frequently activated in acute myeloid leukemia, but in MDS, PI3K/AKT is often down-regulated. To determine whether PI3K down-regulation can perturb HSC function, we g

In particular, bioprinting resolution of digital light processing–based 3D bioprinting suffers with increasin

Abstract Climate and land-use change could exhibit concordant effects that favor or disfavor the same species, which would amplify their impacts, or species may respond to each threat in a divergent manner, causing opposing effects that moderate their impacts in isolation.
