New Englanders are used to cold temperatures, but a combination of extreme cold accompanied by powerful winds is downright dangerous, and enough to send even bundled-up skiers scampering indoors.

Astronomers have discovered 12 new moons around Jupiter, putting the total count at a record-breaking 92.
A study published in a recent issue of INFORMS journal Marketing Science has found evidence of a questionable practice that tricks consumers into thinking they are getting a discount when they are actually paying more.
Volcanoes draw plenty of attention when they erupt. But new research led by the University of Washington shows that volcanoes leak a surprisingly high amount of their atmosphere- and climate-changing gases in their quiet phases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models.
With temperatures on the moon ranging from minus 410 to a scorching 250 degrees Fahrenheit, it's an understatement to say that humans will need habitats with heat and air conditioning to survive there long term.
The universe was simply different when it was younger. Recently astronomers have discovered that complex physics in the young cosmos may have led to the development of supermassive stars, each one containing up to 100,000 times the mass of the sun.
A new method developed at the University of Córdoba has tested how substances secreted by the roots of olive trees impact infection by the Verticillium dahliae fungus, and studied its effects on different varieties of olive trees
Scientists from the Universidad Carlos III de Madrid (UC3M) have designed a new methodology to analyze political polarization through the Facebook posts of European parties. They have also created a website openly displaying these results, where it is possible to make comparisons by country at different times.
Van der Waals heterostructures integrated from various two-dimensional (2D) layered materials provide fundamental building blocks for optoelectronic devices with novel functionalities, such as photovoltaic solar cells, light emitting diodes (LEDs) and photodetectors. Two-dimensional and quasi-two-dimensional perovskites (abbreviated as 2D perovskites hereafter) exhibit unique properties, such as...
How long people live is less predictable and life expectancy for young people can be as much as 14 years shorter in violent countries compared to peaceful countries, according to a new study today from an international team, led by Oxford's Leverhulme Center for Demographic Science. It reveals a direct link between the uncertainty of living in a violent setting, even for those not directly...
Following the Russian invasion of Ukraine from February 24, 2022, energy prices rose by up to 20% worldwide for five months. WTI crude oil was $92.77 per barrel on February 24, 2022, but rose and averaged $106.96 (+15.3%) from February 28 to August 3.
A cascade of various events is required for the transmission of signals within cells. These include several modifications of proteins to switch their function on or off. In order to ensure rapid signal transmission, signaling proteins transiently accumulate at specific sites in the cell, where they can form biomolecular condensates.
A new study shows that a calculation method used by international measurement networks creates a systematic bias in carbon balance estimates for northern ecosystems. The study, led by the Finnish Meteorological Institute, shows that a machine learning method can be used to substantially reduce the error.
Anette Bringedal Houge uses experiences from her own research projects to discuss ethical dilemmas researchers face when working on sensitive topics.
New research has revealed that the process of 'peopling' the entire continent of Sahul—the combined mega continent that joined Australia with New Guinea when sea levels were much lower than today—took 10,000 years.
A recent breakthrough publication by scientists at the Masonic Medical Research Institute have discovered a novel way of treating pulmonary fibrosis, a progressive incurable disease that results in the stiffening of the lungs through scarring, using nanoparticles.
War, budget cuts, a pandemic and a crash: For all its trials, Europe's ExoMars mission might be more deserving of the name Perseverance than NASA's Martian rover.
Experts have warned that the recent detection of bird flu in mammals including foxes, otters, minks, seals and even grizzly bears is concerning but emphasized that the virus would have to significantly mutate to spread between humans.
Baby stars don't always play nice with their siblings. New observations show an outflow of high-speed gas from one baby star colliding with a nearby dense cloud of gas where other stars are in the process of being born. These observations clearly show the outflow from a baby star affecting a neighboring star forming cloud. It is still unknown if it disrupts or enhances star-formation when a baby...
Ceropegia is a genus of plants in the Apocynaceae family, native to Africa, southern Asia, and Australia. According to a recent phylogenetic study, Ceropegia contains more than 700 species in 63 sections. Ceropegia sect. Chionopegia is mainly distributed in the Himalaya region, Pakistan and India eastwards to China. About 18 Ceropegia species belong to sect. Chionopegia in China.
Brown bear management and conservation are the core of heated debates in Romania. As the country harboring the largest population of brown bears in Europe, coexistence between bears and people has always been at the forefront of brown bear management and conservation. Livestock predation is the main source of conflict in rural communities in the Romanian Carpathians, as domestic animals are the...
In all living organisms, DNA replication is essential to ensure the genetic fidelity of the next generation. However, bacteria can also transfer genetic information horizontally to other bacteria. Many species of pathogenic bacteria have transmissible antibiotic resistance plasmids, which are often reproduced through a rolling circle replication machinery. Plasmid pMV158, which is present in the...
Improving suburban public transport access has a societal benefit through better health, increased employment and reduced crime, according to a new study from the Institute of Transport and Logistics Studies at the University of Sydney Business School.
Solar sympathetic filament eruptions usually involve two or more filament eruptions that occur simultaneously or successively within a relatively short time interval with a certain causal linkage. The eruption of one filament may have an effect on another one, thus resulting in the eruption of the other filament simultaneously or successively.
When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers may have structures that are mirror images of each other. Such molecules are called chiral molecules. Scientists are interested in studying such molecules, for example, penicillin,...
