The remains of a 90-million-year-old carnivorous dinosaur distantly related to Tyrannosaurus rex has been discovered in Argentine Patagonia by a team of paleontologists.

Last month was the hottest January since scientists began keeping temperature records in 1880, U.S. government forecasters said Thursday.

A little-known ocean-dwelling creature most commonly found growing on dead hermit crab shells may sound like an unlikely study subject for researchers, but this animal has a rare ability—it can make eggs and sperm for the duration of its lifetime. This animal, called Hydractinia, does so because it produces germ cells, which are precursors to eggs and sperm, nonstop throughout its life. Studying...

Even under modest climate warming scenarios, the continental United States faces a significant loss of groundwater—about 119 million cubic meters, or roughly enough to fill Lake Powell four times or one quarter of Lake Erie, a first-of-its-kind study has shown.

Scientists have a pretty good handle on how the birds and the bees work, but it comes to mating, almost all millipedes have been a mystery—until now. For the first time, researchers have puzzled out how these tiny creatures' complex genitalia work, thanks to new imaging techniques and blacklights that make the different tissues glow. The findings are published in a new paper in the journal...

A research team led by professors from the University of Pittsburgh Department of Physics and Astronomy has announced the discovery of a new electronic state of matter.

Chronic and non-healing wounds—one of the most devastating complications of diabetes and the leading cause of limb amputation—affects millions of Americans each year. Due to the complex nature of these wounds, proper clinical treatment has been limited.

An inexpensive lead sample collection kit distributed to homes in St. Joseph County is comparable in accuracy and sensitivity to more costly in-home analysis, according to research published this month in Environmental Research.

NASA's space snowman is revealing fresh secrets from its home far beyond Pluto.

Researchers from the University of Illinois at Chicago have discovered that endothelial cells—those that create the inner lining of blood vessels—have unique genetic signatures based on their location in the body.

One of the world's most horrific environmental disasters—the 1950 and 60s mercury poisoning in Minamata, Japan—may have been caused by a previously unstudied form of mercury discharged directly from a chemical factory, research by the University of Saskatchewan (USask) has found.

After times of major conflict, such as the civil wars in Liberia from 1980 to 2003, peace often leaves a power vacuum, especially in remote areas not yet reached by a developing government.

NASA satellite imagery revealed that vertical wind shear appears to be affecting Tropical Cyclone Uesi in the Southern Pacific Ocean.

Electrons race along the surface of certain unusual crystalline materials, except that sometimes they don't. Two new studies from Princeton researchers and their collaborators explain the source of the surprising behavior and chart a course for restoring conductivity in these remarkable crystals, prized for their potential use in future technologies including quantum computers.

Since 1998, scientists have documented the global loss of amphibians. More than 500 amphibian species have declined in numbers, including 90 that have gone extinct, due to the fungal pathogen Batrachochytrium, commonly known as chytrid.

Everything a cell does, from dividing in two to migrating to a different part of the body, is controlled by enzymes that chemically modify other proteins in the cell. Researchers at Princeton University have devised a new mathematical technique to describe the behavior of many cellular enzymes. The approach, which will be published February 13 in the journal Current Biology, will help researchers...

How are wild animals managed in European national parks and what factors influence management decisions? The team of Suzanne van Beeck Calkoen and associate professor Dr. Marco Heurich of the Department of Wildlife Ecology and Management at the University of Freiburg has examined differences in national policies for wild animal management in European national parks. Due to major variations in wild...

A new smartphone app to tackle pests destroying crops has been developed—and it could soon help farmers whose lands are being decimated by swarms of locusts, something the UN has called for "rapid action" action on.

A recent research study conducted by City, University of London's Professor Christoph Bruecker and his team, has revealed a novel correlation in the way sealions and rats use their whiskers, which paves the way for the online-monitoring underwater events which trigger riverbed erosion.

Tropical forests are allies in the fight against climate change. Growing trees absorb carbon emissions and store them as woody biomass. As a result, reforestation of land once cleared for logging, mining, and agriculture is seen as a powerful tool for locking up large amounts of carbon emissions throughout the South American tropics.

Organic photovoltaic (OPV) cells have attracted considerable research interest because of advantages of lightweight, flexibility and low-cost solution processing. With the development of organic photoactive materials, especially the new-emerging non-fullerene electron acceptors (NFAs), OPV cells have yielded power conversion efficiencies (PCEs) of over 16% in recent years. However, these devices...

'Tacky' and 'kitsch' religious souvenirs brought back from pilgrimage sites offer pilgrims and their friends and family who cannot make the journey a deeper religious connection.

In warm coastal waters around the world, swimmers can often spot large groups of jellyfish pulsing rhythmically on the seafloor. Unless properly prepared with protective clothing, it is best to steer clear of areas that Cassiopea, or upside-down jellyfish inhabit: getting too close can lead to irritating stings, even without direct contact.

The Chinese puzzle ball is an ornate decorative artwork consisting of several concentric shells that move independently of each other. In the recent decade, Chinese scientists provided a universal method for the fabrication of a conceptually similar micronanoscale structure, called the hollow multishell structure (HoMS).
