A study provides new details about the collective motion of individual agents in a liquid-crystal-like system, which could help in better understanding bacterial colonies, structures and systems in the human body, and other forms of active matter.
It’ll sap funding and political will—but actually, it should.
There's no evidence that dogs, cats, or other household pets are in danger from coronavirus. But you should still wash your hands of their...
On the one-year anniversary of an Ethiopian Airlines crash that killed 157 people — including 18 Canadians — MPs are looking to dig deeper into the federal government's decision to approve the Boeing 737 Max as safe to...
Turtle ant soldiers look like real-life creatures straight out of a Japanese anime film. These tree-dwelling insects scuttle to and fro sporting shiny, adorably oversized heads, which they use to block the entrances of their nests—essentially acting as living doors.
Botanist Cody Coyotee Howard compares bulbs to living bunkers. With an underground stockpile of resources, bulbs can hunker down during disasters and spring up faster than other plants when conditions turn balmy.
Flocks of starlings that produce dazzling patterns across the sky are natural examples of active matter—groups of individual agents coming together to create collective dynamics. In a study featured on the cover of the March 6 issue of the journal Science, a team of researchers that includes Brown University physicists reveals new insights into what happens inside active matter systems.
Plastics are a victim of their own success, so inexpensive, easy to use and versatile that the world is awash in plastic waste. Now researchers from the University of Houston have reported a new method of producing polyolefins—made from hydrocarbons and the most common building block of plastics—structured to address one of the biggest stumbling blocks to plastics recycling.
Viruses—small disease-causing parasites that can infect all types of life forms—have been well studied, but many mysteries linger. One such mystery is how a spherical virus circumvents energy barriers to form symmetric shells.
Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions. The enormous clouds emitting the light are Lyman-alpha blobs (LABs). LABs are several times larger than our Milky Way galaxy, yet were only discovered 20 years ago. An extremely powerful energy source is necessary to produce this...
In a recent study published in Marine Ecology Progress Series, researchers at California Polytechnic State University revealed that in addition to seasonal changes in winds and ocean temperatures, natural climate cycles greatly influenced the base of the food web at the Cal Poly Pier in San Luis Obispo Bay, an embayment located in Central California in the California Current Large Marine...
Some species of fish, notably parrotfish and wrasses living on coral reefs, change their biological sex as they age, beginning life as females and later becoming functionally male. New work from the University of California, Davis, shows that this sequential hermaphroditism evolves when bigger males gain an advantage in reproductive success—for example by defending a permanent mating territory.
In a media briefing Monday, an organization leader said "this virus is capable of spreading easily and sustainably from person to...
Findings suggest the 14-day quarantine period used around world strikes a good balance Coronavirus – live updatesPeople infected with coronavirus are symptom-free for an average of five days, according to a study that reinforces the need for strict quarantine measures.The analysis found that 5.1 days was the median length of time before people started showing signs of illness, although there was...
Turtle ant soldiers and their oddly-shaped heads suggest that evolution is not always a one-way street toward increasing specialization.
Lyman-alpha blobs (LABs) are gigantic clouds of hydrogen gas that produce a special type of ultraviolet light known as Lyman-alpha emission. An extremely powerful energy source must produce this radiation, but scientists debate what that energy source is. A study of Lyman-alpha blob 6 (LAB-6) is the first LAB with strong evidence of an infalling gas feature. The findings suggest that star-forming...
Viruses have been well studied, but many mysteries linger. One such mystery is how a spherical virus circumvents energy barriers to form symmetric shells. A research team has made progress is solving this mystery. The team reports that an interplay of energies at the molecular level makes the formation of a shell possible.
Some species of fish, notably parrotfish and wrasses living on coral reefs, change their biological sex as they age, beginning life as females and later becoming functionally male. New work shows that this sequential hermaphroditism evolves when bigger males gain an advantage in reproductive success -- for example by defending a permanent mating territory.
Barth syndrome is a rare genetic disease in boys that can cause life-threatening heart failure and also weakens the skeletal muscles and the immune system. There is no specific treatment, but new research, involving new mouse models, shows the potential of a gene therapy approach in preventing and reversing cardiac dysfunction in Barth syndrome.

Adam Castillejo, known as the London patient, goes public to give hope to others with illnessThe second person ever to be cleared of HIV has revealed his identity, saying he wants to be an “ambassador of hope” to others with the condition.Adam Castillejo, the so-called London patient, was declared free of HIV last year, 18 months after stopping antiretroviral therapy following a stem cell –...
A clump of grass grows on an outcrop of shale 33,000 years ago. An ostrich pecks at the grass, and atoms taken up from the shale and into the grass become part of the eggshell the ostrich lays.
Scientists have succeeded in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created a flexible organic cell that degrades by less than 5% over 3,000 hours in atmospheric conditions and that simultaneously has an energy conversion ratio -- a key indicator of solar cell performance -- of 13%.
Our brains can predict the popularity of online videos, without us even knowing it.
Bulbs are doomsday preppers, storing up resources underground to ride out disaster. The bigger the bulb, the bigger the stockpile. So, how come their sizes vary so much?
A new study showed that the humans on teams that included a robot expressing vulnerability communicated more with each other and later reported having a more positive group experience than people teamed with silent robots or with robots that made neutral statements, like reciting the game's score.
Scientists have designed and synthesized chains of molecules with a precise sequence and length to efficiently protect 3-D DNA nanostructures from structural degradation under a variety of biomedically relevant conditions. They demonstrated how these "peptoid-coated DNA origami" have the potential to be used for delivering anti-cancer drugs and proteins, imaging biological molecules, and targeting...
Five social scientists holed up in an Amsterdam hotel for a week with the goal of reaching a scientific consensus on how people form stereotypes. Remarkably, they were encouraged by the fact that none of them actually agreed with each other.
Standing desks are so passé. It's time for squatting desks.
Students from different backgrounds in the United States enter college with equal interest in STEM fields—science, technology, engineering and mathematics. But that equal interest does not result in equal outcomes. Six years after starting an undergraduate STEM degree, roughly twice as many white students finished it compared to African American students.

Panic in the City and on Wall Street underlines the need for governments to do (and spend) whatever it takes in dealing with the coronavirus crisisAs coronavirus has spread globally since February, a tenuous balancing act has been attempted in Britain and much of the rest of the world. Governments have assured populations that necessary precautions and preparations are being undertaken to deal...
