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.

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.”

Five new tree-dwelling snake species were discovered in the jungles of Ecuador, Colombia, and Panama. Conservationists Leonardo DiCaprio, Brian Sheth, Re:wild, and Nature and Culture International chose the names for three of them in honor of loved ones while raising awareness about the issue of rainforest destruction at the hands of open-pit mining operations. The research was conducted by Ecuadorian biologist Alejandro Arteaga and Panamanian biologist Abel Batista.

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.

The vital role of oxytocin—the “love hormone”—for social attachments is being called into question. More than 40 years of pharmacological and behavioral research has pointed to oxytocin receptor signaling as an essential pathway for the development of social behaviors in prairie voles, humans and other species, but a genetic study published in the journal Neuron on January 27 shows that voles can form enduring attachments with mates and provide parental care without oxytocin receptor signaling.
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.

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.

While previous studies of incarceration and family life have focused on immediate family—parents, partners and children—a new analysis of a nationally representative survey of U.S. adults that asked about siblings, grandparents, grandchildren, cousins, and other extended family members has found that Black adults in the United States are not only more likely to have experienced family incarceration, but are also more likely to have had more family members incarcerated and to have had family members from more generations ever incarcerated.
Is it acceptable to harm another person? It might depend whether or not there’s a car involved, according to a new study from UK researchers. They showed that people have a shared ‘blind spot’ that can make them use different moral and ethical standards when they think about driving cars, compared to other areas of life.

Birds including swallows and martins—known as aerial insectivores—control insect populations and insect-borne disease and provide hundreds of millions of dollars’ worth of pest control for agriculture. But these feathered friends to humanity are declining at an alarming rate, with species in North America declining more than 30% from 1970 to 2017.
