To get a global view of Earth’s magnetosphere, NASA’s Lunar Environment Heliospheric X-ray Imager (LEXI) is set for a trip to the moon. Scheduled to take off from the Kennedy Space Center in or after mid-January, the instrument will take the first full images of the magnetic field around Earth, which will help researchers reveal how the field fends off solar winds and weather. “We’re trying to get this big picture of Earth’s space environment,” said Boston University physicist and LE ...read more
It’s perhaps historically appropriate that the word “ironic” contains “iron.” Mining and smelting minerals like iron represented technological highs at the Roman Empire’s peak. But those activities also produced enough lead pollution to impair its citizens’ IQs, according to a new study in PNAS.“Detailed ice core records of Arctic lead pollution, together with sophisticated atmospheric modeling and modern epidemiology, indicate that human industrial activities were measurably dam ...read more
New research from the University of Arizona (U of A) claims that Pluto may not have been created with a bang, but with a kiss. The study, published in Nature Geoscience, looks at how Pluto and its moon, Charon, originated after colliding. Instead of destroying each other, the two celestial bodies began to spiral together like a cosmic snowman before separating into two bodies again. What’s unique about the separation is that Pluto and Charon still share the same orbit. This new discovery is ...read more
The clock is ticking for the binary star T Coronae Borealis, as it’s only a matter of time before it explodes in a blaze of light that will be visible here on Earth. Although astronomers aren’t sure exactly when this spectacle will unfold, they say the binary star — given the fiery nickname, the Blaze Star — is likely to ignite later in 2025. The Explosive Cycle of T CrBT Coronae Borealis (T CrB) is a nova located about 3,000 light-years from Earth in the constellation Corona Borealis ( ...read more
After so many years of learning how microbes work, researchers are now digitally recreating their inner workings to tackle challenges ranging from climate change to space colonization.In my work as a computational biologist, I research ways to get microbes to produce more useful chemicals, such as fuels and bioplastics, that can be used in the energy, agricultural, or pharmaceutical industries. Traditionally, researchers have to conduct several trial-and-error experiments on Petri dishes in orde ...read more
"New Year, new me," is a cliche, and yet, each year we set New Year's resolutions. Recent research says that most of us elect to make New Year’s resolutions each year, like exercising more or eating better, even if the resolution may not last past January.According to a new survey from the Physicians Committee for Responsible Medicine/Morning Consult, nearly half of all adults in the U.S. will start a new diet as part of their New Year’s resolutions. The findings indicate that the diets the ...read more
A worker digging up clay in an English limestone quarry discovered a “dinosaur highway” made up of 200 tracks dating back 166 million years. The Oxfordshire footprints include a mix of footprints from both herbivores and at least one carnivore. Most dinosaur toes pointed northward.So just who were these creatures, where were they heading and why were they going there?At least four sets of tracks were likely made by the long-necked herbivores Cetiosaurus, a dinosaur that grew to nearly 60 fee ...read more
In a brilliant development, scientists have discerned the origins of a fast radio burst borne from the magnetic surroundings of a dead neutron star. Its sighting can be traced to a curved glint of light originating from a faraway galaxy. New research from a study in Nature on this luminous phenomenon has issued an updated perspective on fast radio bursts — short-lived explosions of radio waves that release an abundance of energy. Fast Radio Burst 20221022AA fast radio burst (FRB), thought to ...read more
Rangers at Yellowstone National Park are often asked to predict when the next massive volcanic eruption will occur there.A team of USGS scientists, who surveyed the park’s underground magma reservoirs, recently confirmed the standard response, “probably not any time soon.” But they have pointed out that the area where such activity is likely to occur has shifted, according to a report in the journal Nature.Reservoirs of Molton RockIt’s not like there’s been a pattern of frequent, massi ...read more
The sun had a big year in 2024. First, April brought a total solar eclipse that provided a wide swath of the continental U.S. with nearly four minutes of hushed totality. It also gave sun-gazers a chance to observe the outer layers of the sun’s atmosphere, which are normally obscured.Then, on May 10–11, the aurora borealis seemed to appear everywhere, all at once. Reports came from North Texas, Arizona, even Alabama, Florida, and Tennessee — nearly the entire U.S. — that the night sky ha ...read more
