What gives meteorites their shape? New research uncovers a ‘Goldilocks’ answer

Meteoroids coming from outer space are randomly shaped, but many of these, which land on earth as meteorites, are found to be carved into cones. Scientists have now figured out how the physics of flight in the atmosphere …

White police officers are not more likely to shoot minorities

Reports of racially motivated, fatal shootings by police officers have garnered extensive public attention and sparked activism across the nation. New research from Michigan State University and University of Maryland reveals …

Understanding the drivers of a shift to sustainable diets

One of the 21st century’s greatest challenges is to develop diets that are both sustainable for the planet and good for our bodies. An IIASA-led study explored the major drivers of widespread shifts to sustainable diets using …

Astronomers decode Milky Way’s violent birth

The Milky Way gobbled up a galaxy one quarter of its mass 10 billion years ago in a “violent collision” that didn’t fully settle for eons, astronomers said in new research published Monday.

Parasitic plants use stolen genes to make them better parasites

Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host’s nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that …

Machine learning approach significantly expands inovirus diversity

To answer the question, “Where’s Waldo?” readers need to look for a number of distinguishing features. Several characters may be spotted with a striped scarf, striped hat, round-rimmed glasses, or a cane, but only Waldo will …

Molecular sensor scouts DNA damage and supervises repair

In the time it takes you to read this sentence, every cell in your body suffers some form of DNA damage. Without vigilant repair, cancer would run rampant, and now scientists at the University of Pittsburgh have gotten a …

Miniaturized version of ribosome found in microsporidia

A research team lead by MIMS/SciLifeLab research group leader Jonas Barandun, Umeå University, Sweden, uses cryo-electron microscopy to provide near atomic details of the smallest known eukaryotic cytoplasmic protein synthesis …

Study finds Nunavik Inuit are genetically unique

A new study has found that an Inuit population in Canada’s Arctic are genetically distinct from any known group, and certain genetic variants are correlated with brain aneurysm.

Physicists create record-setting quantum motion

Showcasing precise control at the quantum level, physicists at the National Institute of Standards and Technology (NIST) have developed a method for making an ion (electrically charged atom) display exact quantities of quantum-level …

A torque on conventional magnetic wisdom

Physicists at the University of Illinois at Urbana-Champaign have observed a magnetic phenomenon called the “anomalous spin-orbit torque” (ASOT) for the first time. Professor Virginia Lorenz and graduate student Wenrui Wang, …

NASA seeks ideas from US firms on future lunar lander

US space agency NASA on Monday asked American aerospace companies to offer detailed ideas for vehicles that could bring two astronauts to the Moon by 2024, an American objective that was reconfirmed on the 50th anniversary …

New hard X-ray eclipsing polar identified

Using ESA’s XMM-Newton and NASA’s Swift spacecraft, astronomers have found that a hard X-ray source known as 2PBCJ0658.0-1746 is an eclipsing magnetic cataclysmic variable of the polar type. The finding, presented in a paper …

New opportunities for treating kidney failure

Our kidneys can sense when we need them to work a bit harder. As the intestines begin to produce more waste products, the kidneys start to work harder to excrete them. Researchers at, among others, Utrecht University and …

Search for new semiconductors heats up with gallium oxide

University of Illinois electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field’s hottest material—beta-gallium oxide—to their arsenal. Beta-gallium oxide is readily …

Genes linked to death from sepsis identified in mice

Sepsis is a life-threatening condition that occurs when the body’s immune response to infection spirals out of control. Bacteria in the bloodstream trigger immune cells to release powerful molecules called cytokines to quickly …

Astronomers map vast void in our cosmic neighborhood

An astronomer from the University of Hawaiʻi Institute for Astronomy (IfA) and an international team published a new study that reveals more of the vast cosmic structure surrounding our Milky Way galaxy.

Scientists make fundamental discovery to creating better crops

A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory have discovered the specific gene that controls an important symbiotic relationship between plants and soil fungi, and successfully facilitated …

Gut microbes may affect the course of ALS

Researchers at the Weizmann Institute of Science have shown in mice that intestinal microbes, collectively termed the gut microbiome, may affect the course of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s …

Encephalitis identified as rare toxicity of immunotherapy treatment

After a cancer patient receiving an immunotherapy developed encephalitis and died 18 months into treatment, researchers at Vanderbilt-Ingram Cancer Center (VICC) investigated why the complication occurred, performing a molecular …

Unique hybrid implant first installed to a cat

A scientific team from a small innovative enterprise, Biomimetix, based at the National University of Science and Technology MISIS together with their colleagues from the N.N. Blokhin National Medical Research Centre of oncology …

Scientists learn to control the oil lens

Reconstruction of factories (the construction of modern parks and the removal of communications on racks) significantly prevents the penetration of petroleum products into the ground. However, wastes, accumulated as a result …

New record in lead-free halide double perovskites

Illumination consumes more than 20 percent of electricity. Thus, finding an efficient, stable, single-phase warm white-light material is very important. Lead hybrid perovskites have drawn interest for excellent photoelectric …

Solving the salt problem for seismic imaging

The efficient extraction of oil and gas from within the Earth’s crust requires accurate images of subsurface rock structures. Some materials are hard to capture, so KAUST researchers have developed a computational method …

How to stroke a cat, according to science

Many of us will have experienced that super friendly cat who seems to love being stoked one minute, only to bite or swipe at us the next. It might be easy at this point to blame it on the cat, but what’s likely happening …

New nanoantennas to improve ultra-fast wireless connections

Researchers from the Nanophotonic Technology Centre (NTC) of the Polytechnic University of Valencia (UPV) have designed new silicon nanoantennas with direct applications in communication and data processing for the next generation …
