New research techniques are being adopted by scientists tackling the most visible impact of climate change - the so-called greening of Arctic regions. The latest drone and satellite technology is helping an international team of researchers to better understand how the vast, treeless regions called the tundra is becoming greener.
Physicists propose a new way to leverage data from ultra-high energy neutrinos from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica. So far, all nonstandard interaction studies at IceCube have focused only on the low-energy atmospheric neutrino data.
Theoretical physicists have found a deep link between one of the most striking features of quantum mechanics -- quantum entanglement -- and thermalization, which is the process in which something comes into thermal equilibrium with its surroundings.
Previous studies have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar.
New modeling research estimates that up to 75,800 individuals in the Chinese city of Wuhan may have been infected with 2019 novel coronavirus (2019-nCoV) as of Jan. 25, 2020. The authors caution that given the lack of a robust and detailed timeline of records of suspected, probable, and confirmed cases and close contacts, the true size of the epidemic and its pandemic potential remains unclear.
The Institut Pasteur has sequenced the whole genome of the coronavirus known as '2019-nCoV', becoming the first institution in Europe to sequence the virus since the start of the outbreak.
Scientists have developed a nonflammable electrolyte for potassium and potassium-ion batteries, for applications in next-generation energy-storage systems beyond lithium technology. Scientists explain that the novel electrolyte based on an organic phosphate makes the batteries safer and also allows for operation at reduced concentrations, which is a necessary condition for large-scale...
Within quark-gluon plasma, strange quarks are readily produced through collisions between gluons.
Despite the perception that wild birds in farm fields can cause food-borne illness, a new study has found little evidence linking birds to E. coli, Salmonella and Campylobacter outbreaks.
Babies born with low birth weights are more likely to have poor cardiorespiratory fitness later in life than their normal-weight peers. New findings underscore the importance of prevention strategies to reduce low birth weights even among those carried to at term delivery.
The circadian clock system allows the organisms to adjust to periodical changes of geophysical time. Today, increasing evidence show that disturbances in our internal clocks stemming from frequent time zone changes, irregular working schedules or ageing, have a significant impact on the development of metabolic diseases including type-2 diabetes. Using a molecule extracted from lemon peel,...

Nearly 40 years ago, analog data tapes faithfully recorded intense seismic activity in the two months before the historic eruption of Mount St. Helens in Washington State in May 1980. It took some lengthy and careful restoration efforts -- including a turn in a kitchen oven for some of the tapes -- to recover their data.
In a nationwide US survey of 21,678 US high school students, researchers found that nearly 75% of the students' self-reported feelings related to school were negative.
Most people want to change an aspect of their personality, but left to their own devices, they may not be successful in changing, research shows.
Even a relatively short walk to find the nearest bicycle is enough to deter many potential users of bike sharing systems, new research suggests.
Scientists have developed a new TREE method (an acronym short for transient reporter for editing enrichment, or TREE), which allows for bulk enrichment of DNA base-edited cell populations -- and for the first time, high efficiency in human stem cell lines.
The first genetic analysis of schizophrenia in an ancestral African population, the South African Xhosa, appears in the Jan. 31 issue of the journal Science. An international group of scientists conducted the research, including investigators from Columbia University Mailman School of Public Health and New York State Psychiatric Institute, as well as the University of Cape Town and the University...
Infertility likely stems from age-related decline of the ovaries, but the molecular mechanisms that lead to this decline have been unclear. Now, scientists have discovered, in unprecedented detail, how ovaries age in non-human primates. The findings reveal several genes that could be used as biomarkers and point to therapeutic targets for diagnosing and treating female infertility and...
A team of chemists has successfully coupled the directed motion of a light-activated molecular motor to a different chemical unit -- thus taking an important step toward the realization of synthetic nanomachines.
Researchers in Austria use lasers to levitate and cool a glass nanoparticle into the quantum regime. Although it is trapped in a room temperature environment, the particle's motion is solely governed by the laws of quantum physics.
Can buildings learn to save all by themselves? Researchers think so. In their experiments, they fed a new self-learning heating control system with temperature data from the previous year and the current weather forecast. The 'smart' control system was then able to assess the building's behavior and act with good anticipation. The result: greater comfort, lower energy costs.
Researchers have for the first time found a connection between the immune systems of different bird species, and the various climatic conditions in which they live. The researchers believe that as the climate changes, some birds may be exposed to diseases that they are not equipped to handle.
A study of 732,000 accidents over two decades has found that the annual switch to daylight saving time is associated with a 6% increase in fatal car crashes that week.
In uncanny situations, the mere presence of an unknown person can have a calming effect. This is shown in a study of anxiety disorders.
Scientists have discovered how a powerful class of HIV drugs binds to a key piece of HIV machinery. By solving, for the first time, three-dimensional structures of this complex while different drugs were attached, the researchers showed what makes the therapy so potent. The work provides insights that could help design or improve new treatments for HIV.
