As air pollution in Stockholm has decreased, so has the lung capacity of children and adolescents has improved, a new study reports. The researchers consider the results important, since the lung health of the young greatly affects the risk of their developing chronic lung diseases later in life.
Sensing a hug from each other via the internet may be a possibility in the near future. A research team recently developed a wireless, soft e-skin that can both detect and deliver the sense of touch, and form a touch network allowing one-to-multiuser interaction. It offers great potential for enhancing the immersion of distance touch communication.
It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years. And when susceptible deer are infected, they die within days. Now, scientists have found gene variants in deer associated with the animals' susceptibility to EHD.
When scientists disabled a single regulatory gene in a species of sea anemone, a stinging cell that shoots a venomous miniature harpoon for hunting and self-defense shifted to shoot a sticky thread that entangles prey instead, according to a new study.
Warming a crystal of the mineral fresnoite, scientists discovered that excitations called phasons carried heat three times farther and faster than phonons, the excitations that usually carry heat through a material.
Researchers create a network of interacting proteins -- or interactome -- to aid drug discovery.
Scientists have successfully recorded brain activity from freely moving octopuses, a feat made possible by implanting electrodes and a data logger directly into the creatures. The study, published online in Current Biology on February 23, is a critical step forward in figuring out how octopus' brains control their behavior, and could provide clues to the common principles needed for intelligence and cognition to occur.
A new study shows fasting can trigger a negative effect on fighting infection on a cellular level in mouse models.
RNAs can wreak havoc on cells if they aren't removed at the right time. Dis3L2 is a molecular 'machine' that untangles and chews up RNAs, but scientists have been unable to explain how. Biochemists have now pieced together the answer. By shape-shifting, the machine unsheathes a lethal wedge that pries open and chews up RNA molecules, a behavior previously unseen.
Fungal pathogens that cause pine ghost canker are infecting conifer trees in urban forests of Southern California, scientists found.
To eat or to mate -- that is the question (and the answer is: moderately hungry mice choose to mate). Researchers show that hungry mice prioritize interacting with members of the opposite sex over eating and drinking when their brains are stimulated with leptin, an appetite-suppressing hormone.

Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang
A new book describes a dystopian society where we have made life-saving medical care impoverishing, yet are content with the argument that it is still a “good deal”.
Researchers confirmed the existence of a distinct structure inside our planet's inner core - a wickedly hot innermost solid ball of iron and nickel about 1,350 km wide.

On February 22, 1997, a team of British scientists announced the birth of Dolly the sheep, the first clone of an adult mammal. Here is a quiz on cloning
Scientists have built and tested for a thousand cycles a lithium-air battery design that could one day be powering cars, domestic airplanes, long-haul trucks and more. Its energy storage capacity greatly surpasses that possible with lithium-ion batteries.
Experts are calling for more to be done to limit the potentially harmful impact of toxic tire particles on health and the environment.
Biologists use current and historical bird surveys to reveal how land use change has amplified -- and in some cases mitigated -- the impacts of climate change on bird populations in Los Angeles and the Central Valley over the past century. The study found that urbanization and much hotter and drier conditions in L.A. have driven declines in more than one-third of bird species in the region.
