STEM activities with family and educators expose students to diverse career paths

Activities children take part in with family and friends can help shape the fields of study and careers they pursue as adults. A new study published in the International Journal of STEM Education by FIU education researchers Chris Irwin and Zahra Hazari found that STEM activities and conversations with family, friends and teachers are among the strongest factors influencing students' motivations for pursuing STEM (science, technology, engineering and math) careers.

Antarctica's lost mountains may have helped early life flourish

Beneath the vast frozen wastes of Antarctica lie the remains of ancient mountains that have long since eroded. Even though they're no longer standing, they can still reveal a few lost secrets. New research published in Earth and Planetary Science Letters suggests that these vanished peaks may have played a fundamental role in the evolution of complex life on this planet.

Lemur uses opera singer's trick to belt out forest songs

We are often left open-mouthed in awe as an opera singer hits a soaring top note. Now, researchers at the University of Warwick have found that the indri, the world's only known singing lemur, appears to use a strikingly similar vocal technique to hit high notes.

Southern Taurid meteor shower begins ‪—‬ how to spot blazing 'fireballs' from now till November

One of the longest-running meteor showers of the year began on Sunday (Sept. 20), as the Southern Taurids start sending occasional "shooting stars" — and, potentially, spectacular fireballs — across the night sky.The Southern Taurid meteor shower runs from Sept. 20 through Nov. 20, peaking overnight on both Oct. 13-14 and Nov. 4-5, according to the American Meteor Society. Although only about five to 10 meteors per hour can be expected during the shower's peak, the Taurids have a reputation for producing fireballs — very bright meteors that appear as flashes while falling through the atmosphere.Patience is often rewarded with some of the most impressive meteors of the year, partly because th...

Stopping Ozempic may raise heart attack and stroke risk

A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the medications, patients had a 22% higher risk of heart attack, stroke, and death compared with those who stayed on them.

Black holes of every size follow the same surprising rule

Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops to about 2% of the Eddington limit. That same threshold is known to trigger jets from much smaller black holes in the Milky Way.

A new process turns plastic waste into gasoline and diesel fuel

Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based molten salts to break long plastic molecules into smaller hydrocarbons, producing about 60% gasoline under relatively mild conditions.

Scientists create a needle-thin brain implant that can do three jobs at once

A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists a more precise, less invasive way to study the brain and may eventually help treat neurological disorders such as epilepsy.

NASA just powered up Roman’s massive 300-megapixel camera

NASA’s Roman Space Telescope has successfully activated its 300-megapixel infrared camera, which will capture enormous stretches of the cosmos with Hubble-like sharpness. Its planet-hunting coronagraph is also working as expected, putting Roman another major step closer to beginning science operations in 2027.

Amazon study reveals the best strategies for protecting biodiversity and carbon

A large Amazon study suggests the most powerful conservation move may be protecting the forests that are already standing. Preventing damage from wildfires and logging delivered the greatest biodiversity benefits and nearly matched deforestation prevention for protecting carbon. Restoration remains important, particularly where forests have already been heavily cleared, but it was more expensive and less effective on its own.

Chronic stress may be quietly reshaping your heart

Chronic inflammation tied to stress, lifestyle, mental health, and socioeconomic conditions may silently change the heart for years before any symptoms appear. People with the highest inflammation levels faced a 43% greater risk of heart attack and stroke, raising hopes that earlier testing and anti-inflammatory treatments could help prevent serious heart disease.

Stanford scientists discover the human brain may actually be two separate organs

Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also allowed researchers to grow human hindbrain neurons in the lab, opening new possibilities for studying ALS, spinal muscular atrophy, and other brainstem diseases.
