Astronomers investigating one of the most pressing mysteries of the cosmos—the rate at which the universe is expanding—are readying themselves to study this puzzle in a new way using NASA's Nancy Grace Roman Space Telescope. Once it launches by May 2027, astronomers will mine Roman's wide swaths of images for gravitationally lensed supernovae, which can be used to measure the expansion rate of the universe.

The next time you walk through the woods in the dead of winter, take a moment to see if you can spot one of nature's most persistent and heartiest survivors.

Despite efforts to mitigate the effects of climate change, companies are not set up for success due to conflicting national and sectorial targets and differing availability of abatement options, a new study reveals.

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites carry into orbit. As with all space technology, reducing weight means reducing the amount of expensive and greenhouse gas-producing fuel it takes to launch a rocket or increasing the number of devices carried by the same rocket to space.

Research from Dr. Valeriya Vitkova, Senior Lecturer in Corporate Finance at Bayes Business School (formerly Cass), has revealed that merger and acquisition (M&A) deals involving target firms with greater boardroom gender diversity experience fewer leaks of pre-acquisition information than those with male-dominated leadership.

China, the world's top steel producer, is at a crossroads due to its iron and steel industry's heavy CO2 emissions and pollution contribution, spotlighting the urgent need for greener practices. This necessity stems from the industry's impact on air quality and global climate change, driving the push towards adopting sustainable and low-emission technologies to ensure environmental protection and adherence to international climate commitments.

Kilat, the largest living lizard at the Toronto Metro Zoo, like other members of his species (Varanus komodoensis), truly deserves to be called the Komodo dragon. His impressive size and the way he looks at you and tracks your every move makes you realize that he is an apex predator, not unlike a ferocious theropod dinosaur.

A recent report from Ivey Business School's Lawrence National Centre for Policy and Management introduces distinct strategies for achieving gender parity in the workplace, tailored to the predominant gender makeup of different industries.

Geographic sorting along ideological lines is on the rise. Counties and regions of the United States differ in political ideology. But do they differ in personality as well? Further, are people who 'fit' their communities healthier, happier, or more highly achieving than those who do not?

Metropolitan areas with multiple city centers and dispersed green spaces mitigate extreme heat more effectively than those with one dominant city, an analysis by Cornell city planning scholars finds.

As plants are sessile organisms, they must be highly flexible in their ability to adapt to a wide range of environmental conditions in order to survive. Researchers from the Department of Plant Physiology at the RPTU Kaiserslautern are investigating plant adaptation mechanisms, particularly to abiotic stress factors such as light intensity or temperature.

Researchers at the Statewide California Earthquake Center, or SCEC, are unraveling the mysteries of earthquakes by using physics-based computational models running on high-performance computing systems at the Department of Energy's Oak Ridge National Laboratory. The team's findings will provide a better understanding of seismic hazards in the Golden State.

An international team of radiation specialists, biologists and infectious disease experts has found four types of bacteria that are capable of surviving exposure to the hostile Mars environment. In their study, published in the journal Astrobiology, the group exposed four human-infectious bacteria to Mars-like conditions.

Hemp cultivation has exploded in recent years, especially as CBD, a nonpsychoactive cannabinoid, has grown in popularity. As a result, there have been increasing calls—including from the Association of American Feed Control Officers—for CBD's by-product, spent hemp biomass, to be investigated as a potential animal feed ingredient. Is this plentiful fiber source a reliable, healthy new feedstuff for livestock, including dairy cows?

An international team of Earth scientists, evolutionary biologists and paleontologists has unearthed an ancient frog with a belly full of eggs, the oldest known find of its kind. In their paper published in Proceedings of the Royal Society B, the group describes the frog, where it was found, how long ago it lived and where it fits in the frog family tree.

The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team led by Dr. Larysa Baraban at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers.

Dinosaurs' range of locomotion made them incredibly adaptable, University of Bristol researchers have found. In a new study, published today in Royal Society Open Science, findings show that the first dinosaurs were simply faster and more dynamic than their competitors, and it's why they were able to dominate the Earth for 160 million years.

For decades it has been an open question in the ubiquitin research field how proteins are labeled as being defective or unneeded. In a recent study Brenda Schulman, Director at the Max Planck Institute (MPI) of Biochemistry, and Gary Kleiger, Chair of Chemistry and Biochemistry Department at University of Las Vegas Nevada, together with their teams were able to visualize this precise mechanism, catalyzed by the Cullin-RING Ligase E3s, for the first time.

Nanoporous membranes have been shown to be valuable tools for filtering out impurities from water and numerous other applications. However, there's still much work to be done in perfecting their designs. Recently, the lab of Prof. Amir Haji-Akbari has demonstrated that exactly where the nanosized holes are placed on the membrane can make a big difference. The results are published in ACS Nano.

A team of scientists from the U.S. Department of Energy's Ames National Laboratory and SLAC National Accelerator Laboratory has provided new data and analysis on infinite-layer nickelates. This material is a recently discovered class of unconventional superconductors. The results provide new insights into how these superconductors work and how they differ from other superconductors.

Hanging out a lot with the same crowd can make immune systems of individual animals similar, even if the crowd is not related. That's according to a recent paper published in Science Advances that teased out connections between social behaviors and immune cell profiles of lab mice which were allowed to "rewild" and do as they pleased in controlled, predator-free outdoor enclosures.

By attaching molecules together, scientists at Université de Montréal think they've found how molecular systems at the origin of life evolved to create complex self-regulating functions.

Newcastle University researchers have developed a new tool to predict cold-blooded animals' responses to environmental change.

Organogenesis, an important aspect of flowering, helps reveal key processes of plant development such as the formation of floral organs, attainment of reproductive capability, and abscission leading to seed and fruit development.

A team of astronomers has found that the total mass of stars in a galaxy is not a good predictor of the galaxy's abundance of heavier elements, a surprising result according to previous studies. Instead, the gravitational potential of a galaxy is a much better predictor. The findings are published in the journal Astronomy & Astrophysics.
