Last week, scientists with the Washington State Department of Agriculture (WSDA)captured a live Asian giant hornet — known as “murder” hornets for their ability to decimate honeybee populations — and used dental floss to attach a tracking device to its body, which “worked quite well,” said Sven Spichiger, WSDA’s managing entomologist, during a news conference on Monday.
When scientists released the hornet into the wild onto an apple tree, they were initially successful in tracking the insect, but after some time they were unable to locate a signal when
Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study published today in eLife.
The findings in mice could help scientists develop new ways to prevent skin cancer growth that take advantage of the normal mechanisms that control cell growth in the body.
Mutations that activate the protein made by the BRAF gene are believed to contribute to the development of skin cancer. However, recent studies have shown that these mutations do not often cause skin cancer, but instead result in the formation of completely harmless pigmented moles on the skin. In fact, 90% of moles have these cancer-linked mutations but never go on to form tumours. “Exploring why moles stop growing might lead us to a better understanding of what goes wrong in skin cancer,” says lead author Roland Ruiz-Vega, a postdoctoral researcher at
Earlier this month, the editors of Scientific American, published an all-out, endorsement of Joe Biden for President—something unprecedented in the journal’s 175 year history. Then, last week, all of the New England Journal of Medicine’s editors signed a scathing review of the Trump administration’s handling of the COVID-19 emergency, calling for Trump to be voted out of office.
In truth, both editorials offer several valid criticisms of the administration on scientific grounds. And to be clear: The present article is not making any counter-endorsement of Donald Trump—far from it.
Rather, we pose an important question: Are high-profile scientists crossing a dangerous line by using their trusted platforms to influence the election? Based on behavioral science, we believe they are and their actions come at the risk of diminishing the public’s trust in
Marine geologist and oceanographer André Droxler knows Charles Darwin’s theory about atolls is incorrect. But Droxler, who’s studied coral reefs for more than 40 years, understands why Darwin’s model persists in textbooks, university lecture halls, natural science museums and Wikipedia entries.
“It’s so beautiful, so simple and pleasing that everybody still teaches it,” said Droxler, who recently retired from Rice University. “Every introductory book you can find in Earth science and marine science still has Darwin’s model. If they teach one thing about reefs or carbonates in marine science 101, they teach that model.”
Droxler, a professor of Earth, environmental and planetary sciences at Rice for 33 years, is hoping to set the record straight with a 37-page, tour de force paper about the origins of atolls. Published this month in the Annual Review of Marine Science, the paper was co-authored by Droxler and longtime collaborator Stéphan Jorry, a
Researchers from MIPT have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle flux coming from the Sun. The new detector can improve radiation protection for astronauts and spaceships, as well as advancing our understanding of solar flares. The research findings are reported in the Journal of Instrumentation.
As energy gets converted from one form to another in the active regions of the solar atmosphere, streams of particles—or cosmic rays—are born with energies roughly between 0.01-1,000 MeV. Most

LOS ALAMOS, N.M., Oct. 12, 2020–Seven Los Alamos National Laboratory scientists and engineers have been named 2020 Laboratory Fellows: Tanmoy Bhattacharya, Christopher Fontes, Vania Jordanova, Thomas Leitner, John Lestone, Joseph Martz and Ralph Menikoff.
“Recognizing the Fellows of Los Alamos National Laboratory is one of my proudest responsibilities. To be a Fellow is to be a leader at the Laboratory and within the scientific community at large,” said Thom Mason, director of Los Alamos National Laboratory. “Thank you to this year’s seven Fellows for their dedication and exceptional contributions.”
Automated Ionic® Cells to Pure DNA Low Input Kit consistently recovers up to twice the amount of high-quality nucleic acid from as few as 10 cultured or sorted cells
Purigen Biosystems, Inc., a leading provider of next-generation technologies for extracting and purifying nucleic acids from biological samples, today announced the launch of the Ionic® Cells to Pure DNA Low Input Kit for researchers working with limited biological samples. The simplified and automated 60-minute workflow delivers high-quality DNA for the rapid investigation of genetic abnormalities or examination of disease treatment effects.

Provoking a Venus flytrap takes a certain amount of finesse. If you brush just one of the trigger hairs inside of its leaves, the plant likely won’t react. But if you trigger it again quickly enough, it will spring into action, swinging its famous mouth shut.
Waiting for a double trip probably keeps the plant from wasting energy on raindrops or other things that aren’t nutritious flies. But despite centuries of interest in the species, no one was quite certain how the plants remember the first trigger in order to act on a second.
In a paper published last week in Nature Plants, researchers reported they had found the cause: calcium ions. By inducing the flytraps to glow when calcium entered their cells, a team of scientists was able to show how the ions build up as the hairs are triggered, eventually causing the snap.
Astronomers have witnessed a tidal disruption event, where a star whose material was shredded by a nearby supermassive black hole releases an bright flash of light.
The TDE is helping scientists understand more about the gruesome spaghettification process.
The flare occurred just 215 million light-years away from Earth, closer than any other previously observed tidal disruption event.
Astronomers have spotted a rare and radiant pulse of light—the last gasp of a dying star that has been sucked toward the center of a supermassive black hole and shredded into sinuous strings of stardust. This process is delightfully called spaghettification, but make no mistake: it’s gruesome.
🌌 You love our badass universe. So do we. Let’s nerd out over it together.
“When a black hole devours a star, it can launch a powerful blast of material outwards that obstructs our view,” Samantha Oates, an astronomer at the University of Birmingham, said in
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world.
The phenomenon, known as a tidal disruption event, is the closest flare of its kind yet recorded, occurring just 215 million light-years from Earth. It is caused when a star passes too close to a black hole and the extreme gravitational pull from the black hole shreds the star into thin streams of material — a process called ‘spaghettification’. During this process some of the material falls into the black hole, releasing a bright flare of energy which astronomers can detect.
Tidal disruption events are rare and not always easy to study because they are usually obscured by a curtain of dust and debris. An international team of scientists led by the University of Birmingham were able to study this
