Hubble views bright variable star V 372 Orionis and a smaller companion star
Research reveals how redlining grades influenced later life expectancy
The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light-years from Earth.
Perseverance takes a selfie to show off some of its samples
Research from Washington University in St. Louis exposes the deadly legacy of redlining, the 1930s-era New Deal practice that graded neighborhoods by financial risk and solidified the notion that an area's property value was proportional to its racial composition.
Four possible consequences of El Niño returning in 2023
One of the main jobs for the Perseverance Mars rover past few weeks has been collecting carefully selected samples of Mars rock and soil. These samples have been placed and sealed in special sample tubes and left in well-identified places so that a future sample return mission can collect them and bring the Martian samples back to Earth.
It'll take 150 years to map Africa's biodiversity at the current rate, say researchers
Every two to seven years, the equatorial Pacific Ocean gets up to 3°C warmer (what we know as an El Niño event) or colder (La Niña) than usual, triggering a cascade of effects felt around the world. This cycle is called the El Niño Southern Oscillation (ENSO) because every El Niño is naturally followed by a La Niña and vice versa, with some months of neutral conditions in between events. The...
Large number of animal skulls found in Neanderthal cave
The African continent is bursting with biodiversity. In a 2016 report, the United Nations Environment Program wrote: "Africa's biomes extend from mangroves to deserts, from Mediterranean to tropical forests, from temperate to sub-tropical and montane grasslands and savannas, and even to ice-capped mountains."
Restoring land for livelihoods can have ecological benefits, study suggests
A team of researchers affiliated with a host of institutions across Spain, working with one colleague from Portugal and another from Austria, has discovered a large number of animal skulls placed by Neanderthals in Spanish cave more than 40,000 years ago.
Machine learning approach may aid water conservation push in the Colorado River basin
Small-scale restoration efforts that aim to help meet livelihood needs have the potential to contribute to ecological goals in the central Indian landscape, according to a new study published in Restoration Ecology.
New model effectively predicts consumers' retail shopping mobility during a pandemic
The Colorado River basin, which supplies water to 40 million people in the Western United States, is threatened by historic drought, a changing climate and water demands from growing cities. One potential response involves encouraging individuals to conserve water, and a new study may help identify those most likely to change their behaviors to contribute, according to scientists.
Rosy finches are Colorado's high-alpine specialists, and researchers want to know why
COVID-19 forced people to contend with travel bans, stay-at-home orders and closure of nonessential businesses. A new study in the Journal of Business Research reveals how this significant event affected consumer mobility and shopping habits. And the results are hardly what one might predict.
Development of machine vision system capable of locating king flowers on apple trees
Mountaineers who venture high into the Colorado Rockies have likely spotted medium-sized, brown-and-pink birds rummaging around on snow patches for insects and seeds. These high-elevation specialists are rosy finches, a type of bird that's evolved to survive in some of the most rugged places in North America.
Disabled people were Holocaust victims, excluded from German society and murdered by Nazi programs
A machine vision system capable of locating and identifying apple king flowers within clusters of blossoms on trees in orchards was devised by Penn State researchers—a critical early step in the development of a robotic pollination system—in a first-of-its-kind study.
Video: The Sample Transfer Arm: A helping hand for Mars
When Dominic Perrottet admitted to wearing a Nazi uniform to his 21st birthday party, he apologized to Jews and veterans—but not to the other groups who were persecuted by the Nazis, including disabled people.
Gas stoves: Why did they become the pariah du jour?
The mission to return Martian samples back to Earth will use a European 2.5 meter-long robotic arm to pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.
India to get 12 cheetahs from South Africa next month
One-third of U.S. households—more than 40 million homes—cook with gas. There has been much consternation about the danger of gas stoves in the news lately and talk of banning them since a Consumer Product Safety commissioner recently suggested the move.
When alpha mice are trounced by weaklings, they spiral into depression
India will receive 12 cheetahs from South Africa next month that will join eight others it received from Namibia in September as part of an ambitious plan to reintroduce the cats in the country after 70...
The impact of zoos on society is largely underestimated, says study
When two male mice meet in a confined space, the rules of engagement are clear: The lower ranking mouse must yield. But when these norms go out the window—say, when researchers rig such an encounter to favor the weakling—it sends the higher ranking male into a depressionlike spiral. That’s the conclusion of a new neuroimaging study that reveals how the mouse brain responds to an...
Assessing weathering conditions around the globe to understand rate-limiting factors for major rock types
The benefits of zoos to society and local communities are largely underestimated by the wider population, new research shows.
Be kind to bees, build with bee bricks
A quartet of researchers at Pennsylvania State University has assessed differing weathering conditions around the globe in an attempt to better understand the rate-limiting factors for major rock types.
We know that bees are important to natural ecosystems and also to human agriculture and horticulture. They are great pollinators of so plant flowering plant species and are also a source of food and materials we have used for thousands of years, namely honey, honeycomb, and beeswax.
