A new research study published in the October edition of the INFORMS journal Marketing Science (Editor's note: The source of this research is INFORMS) has revealed how taxi drivers use mobile hailing technology to select longer, more profitable trips to optimize their earnings, rather than seeking to increase the number of trips or working hours to achieve higher earnings.

One proposed method for reducing carbon dioxide (CO2) levels in the atmosphere—and reducing the risk of climate change—is to capture carbon from the air or prevent it from getting there in the first place. However, research from Mark Z. Jacobson at Stanford University, published in Energy and Environmental Science, suggests that carbon capture technologies can cause more harm than good.

When you visit Andrew Steckl's lab at the University of Cincinnati, you see a nondescript glass box that weaves together different fibers.

Tropical Storm Kyarr formed near the southwestern coast of India, and NASA's Aqua satellite provided forecasters with a visible image of the storm that revealed it organized quickly.

NASA-NOAA's Suomi NPP satellite passed over the Northwestern Pacific Ocean revealed that Typhoon Bualoi continued to look asymmetric because of ongoing wind shear. The Joint Typhoon Warning Center issued the final bulletin on Bualoi as it was beginning the transition into an extra-tropical cyclone.

NASA-NOAA's Suomi NPP satellite passed over the Gulf of Mexico and revealed that a low pressure area was developing into a depression. On Oct. 25, that low pressure area became Tropical Depression 17.

An international research team led by a physicist at the University of California, Riverside, has identified a microscopic process of electron spin dynamics in nanoparticles that could impact the design of applications in medicine, quantum computation, and spintronics.

Climate activist Greta Thunberg has a tiny new namesake.

Dangers to ancient Antarctic ice portend a future of rapidly rising seas, but a new study may relieve one nagging fear: that ponds of meltwater fracturing the ice below them could cause protracted chain reactions that unexpectedly collapse floating ice shelves. Though pooled meltwater does fracture ice, ensuing chain reactions appear short-ranged.

As the Big Bang theory goes, somewhere around 13.8 billion years ago the universe exploded into being, as an infinitely small, compact fireball of matter that cooled as it expanded, triggering reactions that cooked up the first stars and galaxies, and all the forms of matter that we see (and are) today.

Rich countries have pledged $9.8 billion to help poor nations tackle climate change, the Green Climate Fund said Friday, as environmental activists slammed the United States for refusing to contribute and other nations for giving too little.

When a wildfire obliterates a forest, the first life to rise from the ashes is usually a fungus—one of several species that cannot complete its life cycle in the absence of fire. Scientists have long argued about where and how such pyrophilous (fire-loving) fungi survive, sometimes for decades, between fires. A new study finds that some of these fungi hide out in the tissues of mosses and...

The two fires broke out hours apart and hundreds of miles from each other.

"What are teens doing with YouTube? Practices, uses and metaphors of the most popular audio-visual platform" is the title of an article published in the journal Information, Communication & Society by Fernanda Pires, Maria-José Masanet and Carlos A. Scolari, members of the MEDIUM research group at the Department of Communication at UPF and the Department of Library and Information Science and...

Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe.

A controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population decline in early humans is gaining traction from research sites around the world.

Californian firefighters on Friday battled a fast-moving wildfire north of Los Angeles as further evacuation orders were issued after 40,000 residents were already told to flee their homes.

Scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich have shown that the incidence of midge and fly larvae in amber is far higher than previously thought. The new finds shed light on insect evolution and the ecology in the Baltic amber forest during the Eocene epoch.

The wild orchid trade in China has extended its reach past physical markets to the Internet. With these rare, endangered plants just a click away, the possibility of extinction has escalated.

Too large to be classed as molecules, but too small to be bulk solids, atomic clusters can range in size from a few dozen to several hundred atoms. The structures can be used for a diverse range of applications, which requires a detailed knowledge of their shapes. These are easy to describe using mathematics in some cases; while in others, their morphologies are far more irregular. However,...

Rhomboid proteases are clinically relevant membrane proteins that play a key role in various diseases. Using solid-state NMR spectroscopy, researchers from Berlin's Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have now been able to watch rhomboid proteases in a native lipid environment at work. The obtained dynamic images will be useful for the development of new medication for...

A new integrated modeling framework could help the Indus Basin region find solutions to water resource challenges and interconnected sustainable development goals. The new framework, described in a perspective article published today in the journal One Earth, was developed by IIASA researchers and colleagues working on the Integrated Solutions for Water, Energy, and Land (ISWEL) Project.

Pollutants from coal-fired power plants help make ground-level ozone, and a warming world exacerbates that. Recent rollbacks of U.S. energy regulations may speed climate change, keep pollutants coming, and thus slow the fight against harmful ozone, according to a new study to be published Friday.

The Romans were some of the most sophisticated builders of the ancient world. Over the centuries, they adopted an increasingly advanced set of materials and technologies to create their famous structures. To distinguish the time periods over which these improvements took place, historians and archaeologists typically measure the colours, shapes and consistencies of the bricks and mortar used by...
