In just 50 years, 2 billion to 3.5 billion people, mostly the poor who can't afford air conditioning, will be living in a climate that historically has been too hot to handle, a new study said.

Of the myriad ways researchers are fighting the spread of the coronavirus, studying Tweets may not be the first that come to mind. But now, as in past crises, tapping into one of the world's leading real-time messaging service can help identify new pandemic hotspots, highlight new symptoms, or interpret how people and communities are responding to orders to practice social distancing.
Since Robert Hooke's first description of a cell in Micrographia 350 years ago, microscopy has played an important role in understanding the rules of life.
Susan Fowler turned Silicon Valley upside down in 2017 when she posted an essay on her website about the sexual harassment she experienced while working for Uber.
A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of as nuclear waste in the United States. Although certain elements recycled from waste can be used for powering newer generations of nuclear reactors,...
If warming continues unabated in the Midwest, in 50 years we can expect the best conditions for corn and soybean production to have shifted from Iowa and Illinois to Minnesota and the Dakotas, according to Penn State researchers.
Blood flow in the human body is generally assumed to be smooth due to its low speed and high viscosity. Unsteadiness in blood flow is linked to various cardiovascular diseases and has been shown to promote dysfunction and inflammation in the inner layer of blood vessels, the endothelium. In turn, this can lead to the development of arteriosclerosis—a leading cause of death worldwide—where...
While the global average number of tropical cyclones each year has not budged from 86 over the last four decades, climate change has been influencing the locations of where these deadly storms occur, according to new NOAA-led research published in Proceedings of the National Academy of Sciences.
Overuse of antibiotics, high animal numbers and low genetic diversity caused by intensive farming techniques increase the likelihood of pathogens becoming a major public health risk, according to new research led by UK scientists.
The Princeton University Department of Chemistry publishes research this week proving that an applied magnetic field will interact with the electronic structure of weakly-magnetic, or diamagnetic, molecules to induce a magnetic-field effect that, to their knowledge, has never before been documented.
In tsunami preparedness, it turns out there can be strength in beauty. Rows of green hills strategically arranged along coastlines can help to fend off destruction from tsunamis while preserving ocean views and access to the shore. For some communities, they may offer a better option than towering seawalls.
In Northern Chile's Atacama Desert, one of the driest places on Earth, microorganisms are able to eke out an existence by extracting water from the very rocks they colonize.
Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel.
Here's a new chapter in the story of the miniaturisation of machines: researchers in a laboratory in Singapore have shown that a single atom can function as either an engine or a fridge. Such a device could be engineered into future computers and fuel cells to control energy flows.
A study has solved a long-standing debate about the transport of essential proteins, implicated in many human diseases, through one of the cell's most complex and sophisticated structures.
A Korean research team found a method to inhibit the fouling of membranes, which are used in the desalination process that removes salt and dissolved substances from seawater to obtain drinking, domestic, and industrial water.
Despite the traditional view that species do not exchange genes by hybridisation, recent studies show that gene flow between closely related species is more common than previously thought. A team of scientists from Uppsala University and Princeton University now reports how gene flow between two species of Darwin's finches has affected their beak morphology. The study is published today in Nature...
The change in air pollution in China from January to February as stay-at-home orders were put into place to stop the spread of the coronavirus has intrigued Louisiana State University meteorologist Paul Miller.
While public discussion during and after the 2016 presidential campaign between Donald Trump and Hillary Clinton largely focused on emails and email servers, a team of political science scholars zeroed in on email communications distributed by the campaigns and found that email is still an important campaign tool despite its mundane nature.
Ethanol has five times higher volumetric energy density (6.7 kWh/L) than hydrogen (1.3 kWh/L) and can be used safely in fuel cells for power generation. In Brazil in particular there is great interest in better fuel cells for ethanol as that country distributes low-cost ethanol produced in a renewable way from sugar cane. Theoretically, the efficiency of an ethanol fuel cell should be 96 percent,...
New research from North Carolina State University finds that radiation detectors making use of single-crystal gallium oxide allow for monitoring X-ray radiation in near-real time.
A team of fisheries scientists and marine policy experts, led by a University of Rhode Island researcher, examined how climate change is affecting the ocean environment and found that the changing conditions will likely result in increased fisheries-related conflicts and create new challenges in the management of global fisheries.
When cyclones and other natural disasters strike a city or town, the social and economic impacts locally can be devastating. But these events also have ripple effects that can be felt in distant cities and regions—even globally—due to the interconnectedness of the world's urban trade networks.
The Video Enabled Justice (VEJ) Independent Evaluation was led by academics from the University of Surrey's Department of Sociology and the Centre for Translation Studies in the School of Literature and Languages. Sponsored by the Sussex Police and Crime Commissioner Katy Bourne, the report investigated the impact of a new booking tool used in the organisation of first appearance remand hearings...
In a comprehensive ecological study, a team of scientists at the Max Planck Institute for Chemical Ecology in Jena examined three different species of the genus Drosophila and their interactions with their natural food resources, in particular the yeasts associated with these substrates. They found that vinegar flies do not necessarily prefer yeasts they know from their natural environments, but...
