Hansel and Gretel's breadcrumb trick inspires robotic exploration system for caves on Mars and beyond
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.
Team publishes study of the brain of the Homo erectus fossil with the lowest cranial capacity
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...
New method can provide rapid detection of food adulteration
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.
Study shows promising results in using the sun's ultraviolet rays to decontaminate water at high altitudes
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.
On a warming planet, these Arctic geese rapidly found (and shared) a new migratory route
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.

Haptic holography promises to bring virtual reality to life, but a new study reveals a surprising physical obstacle that will need to be overcome.
Ultracool dwarf binary stars break records

Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 17 hours.
High blood pressure during pregnancy linked to thinking problems later

High blood pressure disorders during pregnancy are associated with an increased risk of thinking problems later in life, according to a study. Researchers found that those with these disorders had a higher risk of cognitive problems in later life than those who did not have high blood pressure during pregnancy. They also found that those with preeclampsia, which is high blood pressure that...
Previously unknown mechanism in precision RNA cleaving by Dicer enzyme revealed
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...
Moose could play a big role in global warming
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.
There’s a Bit of Truth To Some Climate Conspiracy Theories. But That Doesn’t Make Them Right
Having systematically colonized the ranks of government, academia, and media—including malleable-minded climate writers like yours truly—the dark legions of the World Economic Forum (WEF) have reportedly gotten around to their real work: employing their techno-fascist designs on traffic patterns in Oxford, U.K.
Or that’s what some people on the internet are saying, anyway. A...
Scientists synthesize cerium mineral that holds promise for biomedical research
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.
'Swarmalators' better envision synchronized microbots
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.
Weird world of Aussie bees: How one species creates gender balance in the nest
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.
'A nice sign': Big Rockies snowpack may boost Lake Mead
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.
SpaceX Dragon crew to blast off for ISS
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.
Long lost Madagascar songbird seen again in wild
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.
Report: New technology needed to remove greenhouse gases at scale and halt global warming impacts
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.
Rare quasar triplet forms one of the most massive objects in the universe
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.
'Chunky dunk?' Cleveland's prehistoric sea monster may have been shorter, stouter than once believed
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.
P. aeruginosa bacteria produce a molecule that paralyzes immune system cells
Researchers from Freiburg and Strasbourg have discovered a strong immunological effect of the molecule LecB—and a way to prevent it.
Mulching time of forest meadows influences insect diversity
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.
UK now seen as ‘toxic’ for satellite launches, MPs told
After Virgin Orbit’s failed mission, Commons committee hears complaints about regulator Britain’s failed attempt to send satellites into orbit was a “disaster” and MPs are being urged to redirect funding to hospitals, with the country now seen as “toxic” for future launches.Senior figures at the Welsh company Space Forge, which lost a satellite when Virgin Orbit’s Start Me Up mission...
