As a potent storm whips across the southern tier of Canada, opening the door for chilly air in the United States, potentially disruptive winds are poised to roar across portions of the Midwest and Northeast later this week.The blustery winds will first whip across the Upper Midwest on Thursday before reaching the eastern Great Lakes and northern Appalachians by Friday.Widespread power outages are...
How dating apps are adapting to love in the time of coronavirusDating apps are adapting to love in the time of coronavirus, warning their users of the elevated risks of going on dates while trying to ensure they do not switch off entirely when the time comes to self-isolate.OKCupid, which prides itself on its data-led approach to dating, asking users to fill in detailed questionnaires and matching...
Exclusive: Australia needs the expertise to predict changes which have a major impact across the country, a review findsA government-backed review of Australia’s climate science capability has identified “critical gaps” in the nation’s ability to understand the processes that underpin climate change, with atmospheric modelling lagging other countries.It found Australia was in danger of...
It’s hard not to worry, but we have to hope the epidemiologists are giving the UK government the right adviceIn a epidemic, nothing spreads as fast as fear.There are only so many pictures of Italy’s deserted cafes and empty streets that the average Briton can look at without beginning to wonder why we’re not on lockdown too. Social media only feeds the hysteria, spawning endless...

New research has shown that large ecosystems such as rainforests and coral reefs can collapse at a significantly faster rate than previously understood. The findings suggest that ecosystems the size of the Amazon forests could collapse in only 49 years and the Caribbean coral reefs in just 15 years.
The fear of earthquakes is one of the main reasons for reservations about geothermal energy. In order to get hot water from the depths, crevices in the rock underground often have to be created. This is done by injecting large quantities of water under high pressure. The problem is that such hydraulic stimulation is accompanied by vibrations underground, known as 'induced seismicity.' A new study...
From the headphones we use to listen to our favorite songs or podcasts, to sonic camouflage employed by submarines, how we transmit and experience sound is an essential part of how we engage with our surrounding world. Acoustic metamaterials are materials designed to control, direct and manipulate soundwaves as they pass through different mediums. As such, they can be designed and inserted into a...
A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell.
A hypothetical particle called the axion could solve one of physics' great mysteries: the excess of matter over antimatter, or why we're here at all.
A team of researchers has found that the practice of feeding wildlife could be more detrimental to animals than previously thought.
The brain jiggles when the heart beats, and now, researchers have found a way to use that motion to better study the differences between types of neurons. In a new study, researchers find that by analyzing the changes in the waveforms they record from neurons during a heartbeat, they can more accurately classify the different types of neurons in the human brain.
The bulk of new cases were diagnosed and reported on Monday in Italy (1,492), Iran (743), France (410), Germany (317), and South Korea...
More than half of the world's population faces a looming threat to the quality and availability of their drinking water because climate change and urbanisation are expected to cause an increase in groundwater organic carbon, a new UNSW study has found.
Efforts to create synthetic replacements for palm oil are still likely to take several years, so immediate attention should be focused on making the existing production process more sustainable, researchers at the University of Bath's Centre for Integrated Bioprocessing Research (CIBR) and Centre for Sustainable Circular Technologies (CSCT) have found.
France has a law banning face coverings, but it refers to burquas and balaclavas, not surgical...
For more than a decade, two-dimensional nanomaterials, such as graphene, have been touted as the key to making better microchips, batteries, antennas and many other devices. But a significant challenge of using these atom-thin building materials for the technology of the future is ensuring that they can be produced in bulk quantities without losing their quality. For one of the most promising new...
The economic and ecological impact of nature on humans have long been established with prevalent environmental issues such as climate change and over-exploitation of natural resources being the first to cross one's mind. On the other hand, much less attention has been paid to the cultural and social values nature brings to humans. Even though natural wonders such as the Great Barrier Reef and the...

Cattle feeders choose distillers grains in feedlot diets as an inexpensive alternative to corn and soybean meal. But until now, no one had studied the effects of the common feed ingredient on bull development and fertility. With bull fertility to blame for a significant portion of reproductive failures in cow-calf operations, University of Illinois researchers decided it was worth a look.
Silicon is abundant in nature with high theoretical capacity (4200 mAh g-1), making it an ideal anode material for improving the energy density of dual-ion batteries (DIBs). However, its application in DIBs has been restricted by the large volume expansion problem (>300%).

On the Chinese Loess Plateau (CLP), a project named "Gully Land Consolidation" (GLC) has been implemented in rural watersheds to offset the farmland loss induced by "Grain for Green Program". Its main goal includes reshaping creek valleys by incising foot slopes, filling stream channels and ditches, constructing drainage canals, dams and reservoirs, and creating flat farmlands.
