Your native tongue holds a special place in your brain, even if you speak 10 languages
Most people will learn one or two languages in their lives. But Vaughn Smith, a 47-year-old carpet cleaner from Washington, D.C., speaks 24. Smith is a hyperpolyglot—a rare individual who speaks more than 10 languages.
In a new brain imaging study, researchers peered inside the minds of polyglots like Smith to tease out how language-specific regions in their brains respond to...
New England knows winter, but why so dangerously cold?
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.
Jupiter's moon count jumps to 92, most in solar system
Astronomers have discovered 12 new moons around Jupiter, putting the total count at a record-breaking 92.
Asteroid sample shows just what we might need to deflect a surprise killer impactor
Rubble pile asteroids are extremely shock resistant which may explain how they've stayed together for almost as long as the solar system is old. It also has important implications for how we might deal with one that's heading towards the...
Alondra Nelson to leave White House science office
Alondra Nelson, who led the White House Office of Science and Technology Policy (OSTP) during a tumultuous period last year, is leaving next week to return to her faculty position at the Institute for Advanced Study (IAS) in Princeton, New Jersey. Her decision was
first reported
by Axios.
A 64-year-old sociologist, Nelson has a lengthy resume of “firsts” as she...
When you buy at a discount online, are you really paying more?
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.
Repurposed drug battles ‘brain-eating’ amoeba
In the summer of 2021, a 54-year-old man was brought to a hospital in Northern California after an unexplained seizure. When an MRI revealed a mysterious mass in the left side of his brain, he was transferred to the University of California, San Francisco (UCSF), Medical Center. A brain biopsy and other tests revealed not a tumor, but an incredibly rare infection of the central nervous...
With Terence Dickinson's death, we've lost one of Canada's most illustrious sets of eyes on the skies
Dickinson was a prominent popularizer of astronomy, author, magazine editor, and regular contributor to Quirks & Quarks for fifteen...
Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere
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.
Experiments to complete scientific understanding of how reduced gravity affects boiling and condensation
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 first stars may have held up to 100,000 times the mass of the sun
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.
Analyzing the relationship between olive roots and Verticillium wilt
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
Research measures political polarization in Europe through parties' Facebook pages
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.
Two/quasi-two-dimensional perovskite-based heterostructures: Construction, properties and applications
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...
Life in a violent country can be years shorter and much less predictable, even for those not involved in conflict
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...
The spillover effects of rising energy prices following 2022 Russian invasion of Ukraine
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.
Signal transmission in the immune and nervous system through NEMO
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.
Improved estimates of carbon sinks and sources of northern ecosystems
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.
Paper explores how researchers have responsibility for the stories they request and retell
Anette Bringedal Houge uses experiences from her own research projects to discuss ethical dilemmas researchers face when working on sensitive topics.
Remapping the superhighways traveled by the first Australians reveals a 10,000-year journey through the continent
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.
Nano drug delivery breakthrough reveals new possibilities for the treatment of pulmonary fibrosis
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.
Long-delayed ExoMars mission still dreams of 2028 launch
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.
Bird flu detected in mammals but risk to humans low: experts
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.
Outflows from baby star affect nearby star formation
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...
