At dusk, the street lights flicker on around a city park, located not far from the Magdalena River in Colombia. An enormous figure emerges from the shadows. It lumbers forward, stopping to graze on the grass. The scene verges on surreal: A hippopotamus—in South America.

Carry your own cup to the coffee shop. Recycle that soda bottle. Say no to straws.

The U.S. East and Gulf Coasts differ in how ocean and atmospheric circulation and sea level interact to produce storm surges, and both regions will experience greater storm surges as global warming progresses, according to new research from a University of Arizona-led team.

New Cornell University research shows that traditional physics labs, which strive to reinforce the concepts students learn in lecture courses, can actually have a negative impact on students. At the same time, nontraditional, inquiry-based labs that encourage experimentation can improve student performance and engagement without lowering exam scores.

A fungus that attacks almond and peach trees may be key to identifying new drug targets for cancer therapy.

Our microbiomes—the complex communities of microbes that live in, on and around us—are influenced by our diets, habits, environments and genes, and are known to change with age. In turn, the makeup of our microbiomes, particularly in the gut, is well-recognized for its influence on our health. For example, gut microbiome composition has been linked to inflammatory bowel disease, autoimmune...

The fossilized tail of a young dinosaur that lived on a prairie in southern Alberta, Canada, is home to the remains of a 60-million-year-old tumor.

Scientists have made a major breakthrough in understanding how the parasite that causes malaria is able to multiply at such an alarming rate, which could be a vital clue in discovering how it has evolved, and how it can be stopped.

After helping develop a new approach for organic synthesis—carbon-hydrogen functionalization—scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work—a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

More frequent and intense rainfall events due to climate change could cause more landslides in the High Mountain Asia region of China, Tibet and Nepal, according to the first quantitative study of the link between precipitation and landslides in the region.

NASA's Terra satellite passed over the South Pacific Ocean and found a stronger Tropical Cyclone Uesi after obtaining infrared imagery of the storm. Uesi continues moving away from Vanuatu and today is affecting New Caledonia.

Raising awareness and offering technological tools to the thousands of citizens groups in the U.S. that monitor water quality might help community leaders tap these volunteers as a way to improve access to plentiful clean water and possibly avoid water-related crises, according to a team of researchers.

As we lick our Valentine card envelopes and slip into something more comfortable, it's a good time to ponder our sexual relationships.

A new University of Washington study of evictions around the state shows that more women are evicted than men, and in the state's two most populous counties, eviction rates among black and Latinx adults are almost seven times higher than for white adults.

Active-shooter drills in schools expose students to frighteningly realistic scenarios with masked intruders and loud gunfire sounds. They also may be doing more harm than good, says a Rutgers University–Camden nursing scholar who urges school and law enforcement officials alike to include school nurses in their plans to prepare for violent situations.

As the cost of living surges in a number of U.S. cities, what happens to schools when teachers' salaries don't keep pace?

Microbial communities are known to be indispensable for our planet. But surprisingly little is known about how they function. Researchers at the Swiss Federal Institute of Aquatic Science and Technology and ETH Zurich are now shedding a little light on this subject.

Why do most plants and animals engage in sexual reproduction?

Research involving the University of Liverpool has revealed the effect of climate warming on the complex interactions between beech trees and the insects that eat their seeds.

The only therapeutic cancer vaccine available on the market has so far showed very limited efficacy in clinical trials. EPFL researchers are currently working on an alternative. They have developed a platform that allows a cancer vaccine to be delivered to a precise location and stimulate the immune system in a safe way—thereby overcoming one of the two obstacles to creating an effective...

Light could replace invasive techniques to measure brain temperature– eliminating the need to place a thermometer in the brain when treating a range of neurological disorders.

When the machinery that guides the transition of stem cells to somatic cells doesn't shut down properly, cells can become cancerous. Identifying the mechanisms that impede those processes would offer scientists a target for cancer research.

A study of satellite images of dozens of U.S. cities shows trees and vegetation in urban areas turn green earlier but are less sensitive to temperature change than vegetation in surrounding rural regions.

Heavy rain has given hope to Australia's drought-stricken regions, but scientists warned Tuesday sustained falls were needed to end a years-long dry spell.
