A POSTECH research team have crafted a material aimed at swiftly staunching kidney bleeding and facilitating wound recovery. Their research featured in the online edition of Biomaterials.

A mixed diet including native algae gives Australia's prized cultured abalone the colors and appearance preferred by lucrative Asian markets, new research shows.

A new catalyst made from an inexpensive, abundant metal and common table sugar has the power to destroy carbon dioxide (CO2) gas.

Early education programs are widely believed to be effective public investments for helping children succeed in school and for reducing income- and race-based achievement gaps. However, a new study conducted by a team of investigators from Teachers College, Columbia University, University of Virginia, University of California-Irvine, and the University of Delaware finds mixed evidence on the long-term effectiveness of today's preschool programs for helping children succeed in school.

For the first time, the developmental stages of the deadliest human malaria parasite have been mapped in high resolution, allowing researchers to understand this ever-adapting adversary in more detail than previously possible.

Many new drug candidates end up failing because they cause serious side effects in clinical trials even though lab tests involving cell cultures have been successful. This is a common occurrence if the cells used come from animal tissue, for example.

Nucleic acid-based medications such as mRNA vaccines offer tremendous potential for medicine and are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body's cells.

For some years now, the trend in the cosmetics and skincare sector has been toward transparency and natural, sustainable ingredients. A growing number of consumers are rejecting cosmetics that contain petroleum-derived mineral oils and silicone oils. As a result, manufacturers are increasingly turning toward plant-based oils, fats, and waxes as substitutes.

To keep wood from aging prematurely, it's important to protect it effectively against ultraviolet (UV) radiation. At the same time, people want to retain the look and feel of natural wooden surfaces, but the transparent protective coatings that are currently widely commercially available often contain harmful chemical compounds.

Space debris is a growing problem, so companies are working on ways to mitigate it. A new satellite called ADRAS-J was built and launched to demonstrate how a spacecraft could rendezvous with a piece of space junk, paving the path for future removal.

Humankind has never before seen the low frequency radio sky. It is hidden from ground-based telescopes by the Earth's ionosphere and challenging to access from space with traditional missions because the long wavelengths involved (meter- to kilometer-scale) require infeasibly massive telescopes to see clearly.

Parents often worry about the use of social media among children and young people. Caring about this is a good thing, and there are several reasons why you should pay attention, but there is one thing that parents needn't worry about: young people spending time on social media does not impair their interaction with friends offline, according to a new study published in Computers in Human Behavior.

In the shadowy world of counterfeit alcoholic spirit production, where profits soar and brands are exploited, the true extent of this illegal market remains shrouded.

Plant life first emerged on land about 550 million years ago, and an international research team co-led by University of Nebraska–Lincoln computational biologist Yanbin Yin has cracked the genomic code of its humble beginnings, which made possible all other terrestrial life on Earth, including humans.

Kenya and Tanzania were bracing Thursday for a cyclone on the heels of torrential rains that have devastated East Africa, killing more than 350 people and forcing tens of thousands from their homes.

Fourth-grader Ella Araza sat on a tiny plastic box in her Manila slum home, trying to finish her homework before the afternoon sun sent temperatures soaring to unbearable levels.

Endosymbiosis, the intimate and long-term relationship where one organism lives inside another, is a cornerstone of life as we know it, and a key to the emergence of complex life on Earth. Many of the mysteries surrounding endosymbiosis are difficult to tackle using empirical approaches alone.

The Earth now supports over eight billion people who collectively have transformed three-quarters of the planet's land surface for food, energy, shelter and other aspects of the human enterprise.

How often do mountains collapse, volcanoes erupt or ice sheets melt?

A record number of people will go to polls in 2024 to vote in national elections around the world. People who came of age during the last electoral cycle will have an opportunity to cast their votes for the first time.

Some people fear that breaking a mirror can lead to seven years of misfortune. The history of this superstition may go back to the ancient Greeks and Romans, who ascribed mysterious powers to reflected images.

Hvidovre Hospital has the world's first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical sensors—and hopefully pave the way for MRI scans that are better, cheaper and faster.

Semiconductors are a cornerstone of next-generation technology, so a new method to excite atoms in semiconductor materials is likely to excite a broad range of researchers and industries as well.

Aquaculture production operations that help feed the world's growing population also generate polluted wastewater that harms the environment. Four studies published by Purdue University scientists since last May document the feasibility of previously unproven methods for successfully treating the wastewater.

The extraordinary sight of five horses galloping through London, sweating and covered in blood, caused the hashtag #Apocalypse to trend briefly on social media last week.
