A powerful cyclonic storm hurtled into India's southern coast early Thursday, uprooting trees and packing strong winds and rains as tens of thousands of people took refuge in shelters.

Russian oil giant Rosneft on Wednesday announced the start of operations for its giant Vostok oil project in the Arctic, part of the country's strategic energy plan which has been criticised by environmentalists.
Carbon is one of the main building blocks for life on Earth. It's abundant in our planet's atmosphere, where it's found in the form of carbon dioxide. Carbon makes its way into Earthlings' bodies mainly through the process of photosynthesis, which incorporates carbon dioxide into sugars that serve as components for important biomolecules and fuel the global food chain. About a third of this...
For as long as he can remember, Cole Gregg has been interested in space. Last week, the Western University graduate astronomy student had a night he'll never forget as he spotted a previously undiscovered asteroid flashing through the night sky.
Using Planck data from the cosmic microwave background radiation, an international team of researchers has observed a hint of new physics. The team developed a new method to measure the polarization angle of the ancient light by calibrating it with dust emission from our own Milky Way. While the signal is not detected with enough precision to draw definite conclusions, it may suggest that dark...
The infectious disease Tuberculosis (TB) is one of the leading causes of death worldwide. While rates of TB in Canada have remained relatively static since the 1980s, the disease disproportionately affects Indigenous populations. With TB-causing bacteria becoming increasingly resistant to antibiotics, researchers and drug makers are eager to find new, more effective treatments.
The ancient inhabitants of the American Southwest used around 11,500 feathers to make a turkey feather blanket, according to a new paper in the Journal of Archaeological Science: Reports. The people who made such blankets were ancestors of present-day Pueblo Indians such as the Hopi, Zuni and Rio Grande Pueblos.
The next time you visit a lake or the seashore, take a deep breath. As you exhale, take a moment to be thankful for the little things: Specifically, for the microscopic, single-celled algae in the soil and waters all around you that are extracting the carbon dioxide you just exhaled and incorporating it into sugars that will eventually be used by every other organism in the biosphere. About 30% of...
After decades of bitter legal feuds and culture war skirmishes over the fate of wild wolves in the United States, the Trump administration has tried to put a point at the end of the sentence. In stripping gray wolves of their Endangered Species Act protection across the country, the responsible federal agency went against both science and public opinion, and declared the species "biologically...
The spores of some fungi can linger in the environment for months or years just waiting for something to spread them elsewhere, like a gust of wind, falling rain or a passing insect or animal. Not so with Fusarium xyrophilum, a fungus found growing on two types of yellow-eyed grass in the savannas of Guyana, South America, and reported in the December 2019 issue of Mycologia.
Modern microscopes used for biological imaging are expensive, are located in specialized laboratories and require highly qualified staff. To research novel, creative approaches to address urgent scientific issues—for example in the fight against infectious diseases such as COVID-19—is thus primarily reserved for scientists at well-equipped research institutions in rich countries. A young...
A research team led by professors from the Department of Physics and Astronomy have created a serpentine path for electrons, imbuing them with new properties that could be useful in future quantum devices.
Over a period of 39 months, invasive keyhole wasps (Pachodynerus nasidens) at the Brisbane Airport were responsible for 93 instances of fully blocked replica pitot probes—vital instruments that measure airspeed—according to a study published November 25 in the open-access journal PLOS ONE by Alan House of Eco Logical Australia and colleagues. As noted by the authors, the results underscore the...
Twice as much freshwater is stored offshore of Hawai'i Island than was previously thought, according to a University of Hawai'i study with important implications for volcanic islands around the world. An extensive reservoir of freshwater within the submarine southern flank of the Hualālai aquifer has been mapped by UH researchers with the Hawai'i EPSCoR 'Ike Wai project. The groundbreaking...
Nanoparticles are promising drug delivery tools, offering the ability to administer drugs directly to a specific part of the body and avoid the awful side effects so often seen with chemotherapeutics.
The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV, according to a study led by UCL researchers in the i-sense McKendry group.
An international team of about 100 scientists of the Borexino Collaboration, including particle physicist Andrea Pocar at the University of Massachusetts Amherst, report in Nature this week detection of neutrinos from the sun, directly revealing for the first time that the carbon-nitrogen-oxygen (CNO) fusion-cycle is at work in our sun.
Squirrels form a diverse family of rodents. Nearly 300 species have been described, and they occur in every land environment on the planet, from tropical forests to hot and cold deserts. But why are there so many species? A study led by researchers from the Complutense University of Madrid and the Institute of Geosciences (UCM-CSIC) has examined the characteristics of squirrel species that...
Black Friday and Christmas are approaching—it's the time of year when many people gather in stores and other physical meeting places. To be able to handle this, it's important to understand why people are attracted to these places and to plan and prepare for this, says researcher Pernille K Andersson at CTF, Service Research Center at Karlstad University. A pandemic doesn't change people's needs...
Sponges are some of the oldest animals on Earth. They live in a wide range of waters, from lakes to deep oceans. Remarkably, the skeleton of some sponges is built out of a network of highly symmetrical glass structures. These glass scaffolds have intrigued researchers for a long time. How do sponges manipulate disordered glass into the skeletal elements which are so regular? Researchers from B...
Wheat researchers at the John Innes Centre are pioneering a new technique that promises to improve gene discovery for the globally important crop.
Telomeres are specialized structures at the end of chromosomes which protect our DNA and ensure healthy division of cells. According to a new study from researchers at the Francis Crick Institute published in Nature, the mechanisms of telomere protection are surprisingly unique in stem cells.
Freshwater fish reserves are extraordinarily successful at protecting multiple species of fish, a new study of a network of community-based reserves in Thailand has found.
The deep seas—vast expanses of water and seabed hidden more than 200 meters below the ocean surface to depths up to 11,000 meters—are recognized globally as an important frontier of science and discovery.
Regional air-sea coupling plays a crucial role in modulating the climatology and variability of the Asian summer monsoon. The Weather Research and Forecasting (WRF) model, which is a community regional climate model, has been widely used for regional climate studies over Asia.
