The 2.7 billion people who live in China and India—more than a third of the world's population—regularly breath some of the dirtiest air on the planet. Air pollution is one of the largest contributors to death in both countries, ranked 4th in China and 5th in India, and harmful emissions from coal-fire powerplants are a major contributing factor.
Dogs have at least a rudimentary neural representation of meaning for words they have been taught, differentiating words they have heard before from those they have not, new research suggests. When some dogs hear their owners say "squirrel," they perk up or become agitated. They may even run to a window and look out of it. But what does the word mean to the dog? Does it mean, "Pay attention, some

Human and avian youngsters learn behaviors by imitating adults. But learners are selective in who they copy, and scientists don't understand how they choose the right teacher. Young male zebra finches must learn to copy the song of an adult male to mate, but juveniles won't imitate songs played through a loudspeaker or sung by other species of birds. New findings show how the juvenile birds identi
A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, the findings would force significant revisions to several prominent theories posed as alternatives to the Standard Model of particle physics, which was developed in the early 1970s.
Parents often go to great lengths to ensure that their children attend top schools, surrounded by high-achieving peers who often come from advantaged backgrounds.

In the search for highly active and inexpensive electrocatalysts, two reactions pose a particular challenge: the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Both are important for the development of better fuel cells, metal-air batteries, and electrolytic water-splitting. Materials such as platinum, iridium oxide and ruthenium oxide are well suited for these reactions,
The idea of exploring and colonizing Mars has never been more alive than it is today. Within the next two decades, there are multiple plans to send crewed missions to the Red Planet, and even some highly ambitious plans to begin building a permanent settlement there. Despite the enthusiasm, there are many significant challenges that need to be addressed before any such endeavors can be attempted.
The Beaufort Gyre is an enormous, 600-mile-wide pool of swirling cold, fresh water in the Arctic Ocean, just north of Alaska and Canada. In the winter, this current is covered by a thick cap of ice. Each summer, as the ice melts away, the exposed gyre gathers up sea ice and river runoff, and draws it down to create a huge reservoir of frigid fresh water, equal to the volume of all the Great Lakes
The title of Ariana Grande's latest album, Sweetener , reclaims the often-used knock on radio-ready sing-alongs as "saccharine." Perky music doesn't just make life yummier, in Grande's view.

One question that scientists and fitness experts alike would love to answer is whether exercise or nutrition has a bigger positive impact on bone strength.
Flash drought is a rapidly intensifying water deficit process accompanied by high temperatures in a short period of time. Recently, heat extremes have become more frequent in a warming climate, and have substantially increased the occurrence of flash drought, which threatens crop yields and water supply.
Europe's future climate will be characterised by more frequent heat waves and more widespread drought. Heat and drought will both challenge crop production, but drought in particular will be a problem—especially for spring sown crops such as maize.

The stories are also familiar: Some fear gangs and death threats, others flee rape and domestic violence. Just months after a caravan of migrants bound for the U.S. gained national attention in April , anot
Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. In experiments, Seminavis robusta diatoms directed their orientation either towards nutrient sources or mating partners, depending on the degree of starvation and the need to mate.
Can humans drive economic growth, meet rising demand for food, energy and water, and make significant environmental progress? The short answer is 'yes,' but it comes with several big 'ifs.' New research shows that we can put the world on a path to sustainability if we make significant changes within the next 10 years.

A new policy brief released today — World Food Day — highlights the link between recognizing community land rights and ensuring global food security and climate protection. The brief notes that the failure of governments around the world to recognize community land rights leaves community lands vulnerable to expropriation for large-scale agriculture, mining, or infrastructure, which typically be
Since the reintroduction of wolves to Yellowstone National Park in 1995, the park's ecosystem has become a deeply complex and heterogeneous system, aided by a strategy of minimal human intervention. The new study is a synthesis of 40 years of research on large mammals in Yellowstone National Park, conducted by University of Alberta ecologist Mark Boyce.
A new statistical method that tests for equivalence, rather than difference, has a role to play in dismantling gender and publication biases in science. The authors believe the technique has broad applicability across disciplines and can help remove publication bias against "negative results," opening the door to a broader investigation of natural phenomena. The paper includes an example of the te
While conservatives and liberals tend to disagree on many environmental issues, they both view the development of solar power and other forms of renewable energy as financially savvy and a step towards self-sufficiency.
Environmental scientists argue that societies should embrace population aging and decrease. They cite multiple reports of the socioeconomic and environmental benefits of population aging, mortality-related decrease, and shrinking workforces due to retirement and maintain that, contrary to some economic analyses, costs associated with aging societies are manageable, while smaller populations make f
Europe's future climate will be characterized by more frequent heat waves and more widespread drought. Heat and drought will both challenge crop production, but drought in particular will be a problem — especially for spring sown crops such as maize.
Biological engineers have devised a way to regulate the expression of messenger RNA once it gets into cells, giving them more precise control over gene therapy treatments for cancer and other diseases.
