A new study led by researchers at the University of North Carolina at Chapel Hill Institute for the Environment, Boston University School of Public Health and the Environmental Defense Fund finds that pollution from oil and gas venting and flaring results in…

Sand ripples are fascinating. They are symmetrical, yet wind — which causes them — is very much not. Furthermore, they can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could…

The ‘ultrasound-photoacoustic dual-modal imaging system’ combines molecular imaging contrast with ultrasound imaging, and it can visualize molecular and structural information inside the body in real-time without any ionizing radiation. This advantage gives it the potential to enhance medical diagnosis by providing diverse…

With the help of 16 grants from the National Science Foundation, researchers have painstakingly taken computed topography (CT) scans of more than 13,000 individual specimens to create 3D images of more than half of all the world’s animal groups, including mammals, fishes,…

Optical properties of afterglow luminescent particles (ALPs) in mechanoluminescence (ML) and mechanical quenching (MQ) have attracted great attention for diverse technological applications. Recently, a team of researchers from Pohang University of Science and Technology (POSTECH) has garnered attention by developing an optical…

When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training — such…

The DNA carries the genetic information of all living organisms and consists of only four different building blocks, the nucleotides. Nucleotides are composed of three distinctive parts: a sugar molecule, a phosphate group and one of the four nucleobases adenine, thymine, guanine…

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the earth drives evaporative processes. Since 2017, researchers have been working to harness the energy potential of…

The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.…

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe. The method can detect…

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise doubts that materials pulled last year…

A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, an international team of astronomers led by the University of Cambridge have spotted a ‘dead’ galaxy when…

Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to research from Washington University in St. Louis. On Aug. 17, 2017, the Laser Interferometer Gravitational-wave Observatory (LIGO), in the…

If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you’re not alone. A new study from University of Waterloo researchers found that people had more difficulty than was expected distinguishing…

Scientists led by an Oregon State University chemistry researcher are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater. Kyriakos Stylianou of the OSU College of Science led an international team that identified a material known as…

In a series of studies, a team of astronomers has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, represent one of the…

Scientists have developed a new robot that can ‘mimic’ the two-handed movements of care-workers as they dress an individual. Until now, assistive dressing robots, designed to help an elderly person or a person with a disability get dressed, have been created in…

Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Initially detected with NASA’s Hubble Space Telescope,…
