House hunting on Mars could soon become a thing, and researchers at the University of Arizona are already in the business of scouting real estate that future astronauts could use as habitats. Researchers in the UArizona College of Engineering have developed technology that would allow a flock of robots to explore subsurface environments on other worlds.

The paleoneurologist Emiliano Bruner and the archaeologist Sileshi Semaw, both from the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have published a paper in the American Journal of Biological Anthropology about the 1.5 million-year-old cranium DAN5/P1, found at the Gona site in Ethiopia, whose cranial morphology indicates that it belongs to the species Homo erectus, and...

University of Missouri scientist Colleen Ray can now add the job of "food detective" to her resumé. Recently, Ray and colleagues in the Department of Chemistry developed a novel method—using nuclear magnetic resonance (NMR) spectroscopy—to detect whether food products have been modified or adulterated with fillers like vegetable oil.

Research shows that solar water disinfection (SODIS) may be just as effective at decontaminating Escherichia coli (E coli) infected water at high altitudes as it is at low altitudes. The results of a new study appearing in the Wilderness Medical Society's official journal Wilderness & Environmental Medicine show promise for improving global access to safe drinking water.

As the planet warms, animals that breed in the Arctic are at particular risk. But a new study reported in Current Biology on March 1 offers some encouraging news: in an apparent reaction to pressures along their former migratory route, a population of Arctic geese has rapidly adjusted, forming a new migration route and breeding location almost 1,000 kilometers from their original stomping grounds.

Researchers at the Center for RNA Research, Institute for Basic Science (IBS), in Seoul, have published a study with critical new insights into the structure and function of the Dicer enzyme. Dicer is an enzyme required for the biogenesis of miRNAs and small interfering RNAs (siRNAs), which in turn are drivers of RNA silencing and post-transcriptional regulating of gene expression, one of the...

One of the biggest potential single sources of carbon emissions from wooded parts of Norway has four legs, weighs as much as 400-550 kg and has antlers.

Trinity geoscientists have developed a cheap and environmentally friendly method for the synthesis of the rare earth mineral which holds promise for the treatment of diseases associated with inflammation, including cancer.

Imagine a world with precision medicine, where a swarm of microrobots delivers a payload of medicine directly to ailing cells. Or one where aerial or marine drones can collectively survey an area while exchanging minimal information about their location.

New Flinders University research gives insights into the fascinating world of Australian native bees, finding that one highly evolved species has been shaped by an unusual battle between male and female offspring numbers.

It's not even March yet, but the mountains that feed the Colorado River already have seen more snow this winter than they normally would through an entire snow season.

A SpaceX Falcon 9 rocket is to make a second attempt on Thursday to blast off for the International Space Station carrying two NASA astronauts, a Russian cosmonaut and the second Emirati to voyage to space.

Conservationists were celebrating Wednesday the first sightings in 24 years of the dusky tetraka, a yellow-throated songbird native to Madagascar for which ornithologists had feared the worst.

The impacts of climate change are being felt around the world. Limiting global warming requires not just dramatically reducing future emissions but removing greenhouse gases from the atmosphere already released.

Ultra-massive black holes are the most massive objects in the universe. Their mass can reach millions and billions of solar masses. Supercomputer simulations on Texas Advanced Computing Center (TACC)'s Frontera supercomputer have helped astrophysicists reveal the origin of ultra-massive black holes formed about 11 billion years ago.

About 360 million years ago, in the shallow subtropical waters above what is now the city of Cleveland, an armor-plated fish many believed to be up to 30 feet long ruled the seas.

Researchers from Freiburg and Strasbourg have discovered a strong immunological effect of the molecule LecB—and a way to prevent it.

Mulching is a possible management method for forest meadows and is important to their upkeep. During the process, the meadow is cut and the cuttings are shredded and left on the meadow. Despite its significance, the effects of this method on insects living in this habitat has rarely been studied up to now.

As the saying goes, "When life gives you lemons, turn that tartness into little translucent balls in which to grow your young." At least, that's how the saying goes for a tiny insect called a cynipid wasp, whose larvae were recently discovered inducing plant growths called galls that contained acidity levels akin to lemons.

The tumor suppressor protein p53, known as "the guardian of the genome," protects the body's DNA from daily stress or long-term damage by triggering the cells to make repairs or to self-destruct. But mutations in the p53 gene that codes for the protein can prevent it from performing its job, making errors accumulate in the genetic code and leading to diseases like cancer.

A team of global experts has discovered new signals of natural selection in humans.

Seagrass: green leaves swaying in the currents. Fish weave their way through, and sea turtles graze. They're always on their guard, watching out for any encroaching sharks. The seagrass' roots are hidden in the seabed, where they anchor the sand, securing the coastline. The best-kept secret is the amount of carbon these plants store: even more than trees do. But seagrasses are facing a barrage of...

Novel research involving University of Liverpool academics has shown that expanding the use of liquefied petroleum gas (LPG) and/or grid electricity to replace biomass-fueled cooking in low- and middle-income countries (LMICs) significantly benefits human health and climate.

Researchers have designed and demonstrated two all-silicon terahertz metasurface devices that can be used to create four optical channels for simultaneously implementing different optical functions. This capability could be useful for a variety of applications such as communication, terahertz imaging, particle manipulation or encoding quantum information.
