When it comes to sexual competition, males have the star role. Clashing bodies, locking horns, biting and kicking are all considered fair play. Since these behaviors are so salient and robust, most studies focus on male behavior, leaving females aside.

Theorists at the University of Pittsburgh and Swansea University have shown that recent experimental results from the CERN collider give strong evidence for a new form of matter.

For the first time, scientists will be able to test therapeutics for a group of rare neurodegenerative diseases that affect infants and young children, thanks to a new research model created by scientists at the University of Wisconsin-Madison. Their results are published in the Proceedings of the National Academy of Sciences.

Physicists at UC Santa Barbara, the University of Maryland, and the University of Washington have found an answer to the longstanding physics question: How do interparticle interactions affect dynamical localization?

In a discovery with wide-ranging implications, researchers at the University of Massachusetts Amherst recently announced in the Proceedings of the National Academy of Sciences that uniformly charged macromolecules—or molecules, such as proteins or DNA, that contain a large number of atoms all with the same electrical charge—can self-assemble into very large structures. This finding upends our understanding of how some of life's basic structures are built.

Among the counties that trace the coastline of the contiguous United States, two very different pictures emerged from the latest census.

The year was 1987, and Earth's shield against the giant thermonuclear reaction in the sky was failing.

If you're an avid reader of science news, you've probably heard of viral proteins such as the COVID-19 spike protein.

Donna Kalil loves snakes. She's been fascinated by them since she was a kid living in the mountains of Venezuela's capital in the 1960s, where her father was stationed as an Air Force pilot.

Smartphone users will be disappointed if they expect their devices and social media to fill their need for purpose and meaning. In fact, it will probably do the opposite, researchers at Baylor and Campbell Universities have found in a recently published study.

About 2 billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor—most likely an asteroid—formed what is today the biggest crater on our planet. Scientists have widely accepted, based on previous research, that the impact structure, known as the Vredefort crater, was formed by an object about 15 kilometers (approximately 9.3 miles) in diameter that was traveling at a velocity of 15 kilometers per second.

Cuba on Monday declared a cyclone alert in its six most western provinces as fast-approaching Hurricane Ian strengthened rapidly, with Florida also ramping up preparations ahead of a possible hit.

With the help of geomagnetic surface surveys and subsequent hands-on digging, an excavation team from Johannes Gutenberg University Mainz (JGU) has revealed new insights into the area in which the caliph's palace of Khirbat al-Minya was built on the shores of the Sea of Galilee. According to these findings, there had already been a settlement occupied by Christian or Jewish inhabitants in the immediate vicinity long before the palace was built.

University of Central Florida material sciences engineers Melanie Coathup and Sudipta Seal have designed a cerium oxide nanoparticle—an artificial enzyme—that protects bones against damage from radiation. The nanoparticle has also shown abilities to improve bone regeneration, reduce loss of blood cells and help kill cancer cells.

Tropical Storm Ian was forecast to rapidly gain strength Sunday while racing across the Caribbean toward Cuba and threatening a big hit to Florida's west coast later in the week.

The American Wild Horse Campaign released a report Friday documenting that 1,020 federally-protected wild horses and burros have been sold at slaughter auctions in the last 22 months.

"Forever chemicals" are everywhere. The thousands of chemicals in the group known as perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are found in cookware, packaging, cosmetics, clothing, carpet, electronics, firefighting foam and many other products.

A new Yale School of the Environment-led analysis identifying gaps in maps that help forecast range contractions for African species found that all species studied have a portion of their range at risk and small carnivores warrant more concern.

What happens belowground in a corn field is easy to overlook, but corn root architecture can play an important role in water and nutrient acquisition, affecting drought tolerance, water use efficiency, and sustainability. If breeders could encourage corn roots to grow down at a steeper angle, the crop could potentially access important resources deeper in the soil.

Without altering the genetic code in the DNA, epigenetic modifications can change how genes are expressed, affecting an organism's health and development. The once radical idea that such changes in gene expression can be inherited now has a growing body of evidence behind it, but the mechanisms involved remain poorly understood.

The rise in local banking branches closing across the UK has increased the demand for access to cash deposit services at Post Offices, new research has found.

Recently, a study led by Dr. Yilin Chen, Prof. Yong Qin, Dr. Jiuqing Li, Associate Prof. Zhuangfu Li, Tianyu Yang (China University of Mining and Technology) and Dr. Ergang Lian (Tongji University) was published in Science China Earth Sciences. The research team identified natural carbon onions (onion-like fullerenes) in intrusion-affected coal samples collected from Permian coal-bearing strata in the Yongan Coalfield, Fujian Province, South China. They found the largest natural carbon onions (with... Читать дальше...

This study was led by Prof. Xinhua Peng and Prof. Min Jiang who have been devoted to developing spin-based quantum technologies for the detection of weak magnetic fields for many years.

Infertility is a global public health problem caused by genetic defects, lifestyle, nutrition, and factors affecting the local metabolism and microenvironment of the reproductive system. Sperm from the testis must enter the epididymis to undergo a series of structural, biochemical and functional changes before they can gain maturity and become capable of fertilization. The influence of the epididymis on sperm maturation is highly susceptible to aging, stress and local metabolic factors.

One way to better understand an atom is to shoot a particle at it and infer the atom's properties based on how the particle bounces off it. In the mid-1930s, the physicist Enrico Fermi showed that one measurable number—the scattering length—illuminated everything that could be known about an electron scattering off an atom, or a neutron scattering off a nucleus.
