Wildlife need to move to survive: to find food, reproduce and escape wildfires and other hazards. Yet as soon as they leave protected areas like national forests or parks, they often wind up on a landscape that is very fragmented in terms of natural boundaries and human ones.

The low-pressure area that had once been Tropical Cyclone Francisco has been lingering in the Southern Indian Ocean since Feb. 6 when it weakened below tropical cyclone status. Since then, Francisco's remnants moved into an area of warm waters and low wind shear allowing the low-pressure area to re-organize, consolidate and re-form. NASA's Aqua satellite provided forecasters with a visible image...

A new study led by the University of Hawai'i (UH) at Mānoa has helped refine understanding of the amount of hydrogen, helium and other elements present in violent outbursts from the Sun, and other types of solar "wind," a stream of ionized atoms ejected from the Sun.

From the time that dinosaur fossils were first discovered, these creatures have fascinated scientists and laypeople alike. In the academic world, their remains provide important clues into the prehistoric world; in popular culture, dinosaurs have inspired blockbuster hits, such as Jurassic Park and King Kong.

Research by an international team of scientists led by University of New Mexico Professor Yemane Asmerom suggests contraction of the Intertropical Convergence Zone (ITCZ) during a warming Earth, leading in turn to drying of the Neotropics, including Central America, and aggravating current trends of social unrest and mass migration.

University of Central Florida researchers are helping to close the gap separating human and machine minds.

Delta Air Lines said Friday it plans to invest $1 billion over the next decade to reduce its emissions, the first major airline to make such a commitment.

Every social network has its fake news. And in animal communication networks, even birds discern the trustworthiness of their neighbors, a study from the University of Montana suggests.

Coral reefs account for one-third of all biodiversity in the oceans and are vital to humanity. But long-standing human stressors including agricultural run-off and overfishing and more recent ocean warming from climate change have all contributed to large-scale coral reef die-offs.

Researchers at the University of Cambridge have developed a novel technique for generating single photons, by moving single electrons in a specially designed light-emitting diode (LED). This technique, reported in the journal Nature Communications, could help the development of the emerging fields of quantum communication and quantum computation.

Police use of lethal force in the United States has triggered public scrutiny of violent interactions between police and citizens. Past research has focused on whether race and levels of violence contribute to this phenomenon. A new study expands on prior research by examining the impact of the availability of firearms. It finds a pronounced positive relationship between statewide prevalence of...

Although it is now an "ex-tropical cyclone," Uesi continues to generate some moderate rainfall, especially in its southern quadrant as it moves toward New Zealand.

Researchers from the group of Vlad Cojocaru together with colleagues the Max Planck Institute in Münster (Germany) have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem cells. Their findings are published in the Biophysical Journal.

Hydropower dams, which use flowing water to turn a series of turbines to generate electricity, provide a source of energy that doesn't rely on fossil fuels. But they also disrupt the flow of rivers, and impact the fish and people that live there.

The last time a list was compiled of all the chemicals available on the market and in circulation worldwide, it ran to 100,000 entries. Drawn up shortly after the turn of the millennium, the list focused on markets in the US, Canada and western Europe, which made sense because 20 years ago, these countries accounted for more than two thirds of worldwide chemical sales.

Influenza is a deadly virus, with about 290,000 to 650,000 deaths worldwide each year. When pandemics hit, the toll can soar: The Spanish flu of 1918 caused 40 million to 50 million deaths, the Asian flu of 1957 caused 2 million deaths, and the Hong Kong flu of 1968 caused 1 million deaths.

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the...

Seagrasses have long been known as some of Earth's most remarkable organisms—descendants of flowering land plants that have re-colonized the ocean by developing traits that allow them to grow, pollinate, and release seeded fruits while fully immersed in salty seawater.

Cereals from the Fertile Crescent and broomcorn millet from northern China spread across the ancient world, integrating into complex farming systems that used crop-rotation cycles enabled by the different ecological regions of origin. The resulting productivity allowed for demographic expansions and imperial formation in Europe and Asia. In this study, an international, interdisciplinary team of...

Drs. Chaun Jang, Jun Woo Choi, and Hyejin Ryu of the Korea Institute of Science and Technology (KIST, President Lee Byung Gwon) have announced that their team at KIST's Center for Spintronics successfully controlled the magnetic properties of FGT (Fe3GeTe2) in a joint research project with Dr. Se Young Park and his team at the Center for Correlated Electron Systems at the Institute for Basic...

Due to their excellent performance in manipulating electromagnetic (EM) waves freely and flexibly, metasurfaces have been widely investigated since the beginning of the 21st century. However, with the rapid development of digital information technology, the traditional analog metasurfaces with continuous phase control become difficult to control digital information. In 2014, digital coding and...

Hyperlipidemia, one of the most common threats to human health, refers to an abnormal increase of cholesterol and/or triglycerides in the blood. One effective method for prevention and treatment of the disease is cholesterol-lowering therapy, such as the drug simvastatin.

The smallest proteins travel in our cells, completing deeply important tasks to keep our molecular mechanisms moving. They are responsible for transporting cargo, duplicating cells and more. Now, a research team based in Japan has uncovered more about how these proteins move.

Under JST's Strategic Basic Research Programs, Noda Nobuo (Laboratory Head) and Fujioka Yuko (Senior Researcher) of the Institute of Microbial Chemistry, in collaboration with other researchers, discovered that a liquid-like condensate (liquid droplets) in which the Atg protein is clustered through the liquid-liquid phase separation is the structure responsible for the progression of autophagy.
