Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...

When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the planetary effects from the impact ...

By stacking transistors on top of one another, rather than laying them side by side on a flat chip, many electronic engineers are hopeful that vast amounts of computing power could be packed into tiny spaces, all while cutting ...

A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.

More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have ...

Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...

In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately ...

Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including ...

Mosquito repellents are key to protecting ourselves from mosquito bites and the pathogens they might carry. The most widely used active ingredient in insect repellents is N,N-diethyl-meta-toluamide, commonly known as DEET.

Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors. The ...

Chikungunya virus, which is transmitted to people by infected Aedes mosquitoes and characterized by high fever and intense joint swelling and pain, has made a resurgence in many countries around the world in recent years.

Faculty in the Cockrell School of Engineering have developed a rare printer as part of a larger project to speed up production and lower costs of manufacturing semiconductors critical to modern electronics.
