A protein analysis of an 800,000-year-old tooth suggests the supposed cannibal species Homo antecessor was only distantly related to humans and Neanderthals. more

A fossilised seal tooth found on a Victorian beach could hold the key to uncovering the history and geography of earless seals that graced Australia's shores three million years ago. more

The ADMX collaboration, a group of researchers working at universities across the U.S. and Europe, has recently performed a new search for invisible axion... more

Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal... more

Teeth can do more than just masticate. A new study has found that the teeth serve as one's archive in life, recording biological events, from tooth formation to death. more

Cavitation is a common damage mechanism in soft solids. Here, we study this using a phase separation technique in stretched, elastic solids to controllably nucleate and grow small cavities by... more

Frequency-stabilized optical frequency combs have created many high-precision applications. Accurate timing, ultralow phase noise, and narrow linewidth are prerequisites for achieving the ultimate performance... more

Cavitation refers to the formation and collapse of vapor bubbles near solid boundaries in high-speed flows, such as ship propellers and pumps. During this process, cavitation bubbles focus fluid energy... more

Researchers in the Department of Biomedical Engineering— a shared department in the schools of Dental Medicine, Medicine, and Engineering—have been working to develop a new, low-cost,... more

Researchers from the Department of Energy’s SLAC National Accelerator Laboratory have discovered a strange new feature of a protein that’s thought to be important in the... more

High-repetition-rate pulsed lasers serve a wide range of applications, from optical communications to microwave photonics and beyond. Generating trains of ultrashort optical pulses commonly involves locking phases of longitudinal laser... more

This discovery may be fundamental for the understanding and design of new, nanometric size, opto-electronic devices which will be key for the development of... more

Teeth constitute a permanent and faithful biological archive of the entirety of the individual's life, from tooth formation to death, a team of researchers has found. Its work provides new... more

Photonic cavities are an essential part of many modern optical devices, from laser pointers to microwave ovens. Just as we... more

Researchers from the Department of Energy's SLAC National Accelerator Laboratory have discovered a strange new feature of a protein that's thought to be important in the development of tuberculosis: The protein contains... more

The Governor of Michigan has ordered a halt to doctors and dentists on all nonessential medical procedures more

Semiconductor nanowire lasers are a crucial component for on-chip integrated optoelectronics. However, silicon-integrated, room-temperature, continuously-operating and electrically-pumped nanowire lasers have not yet been demonstrated. In this work, a... more

Class B G protein–coupled receptors, an important class of therapeutic targets, signal mainly through the Gs class of heterotrimeric G proteins, although they do... more

Analysing 2500-year-old teeth has thrown open a window onto life and gender inequality during Bronze Age China. more

A new study published in the journal JAMA Network Open in March 2020 shows that dentists can eliminate opioid analgesia from their armory of pain reliever after a tooth extraction, or at least dramatically reduce its... more

The CENIEH has conducted the first study which tackles counting the two types of enamel growth lines, in Lower Pleistocene and Middle... more

The building blocks of superconducting accelerators are superconducting radiofrequency (SRF) cavities made primarily from niobium that are combined in a vessel and bathed in liquid helium to reach superconducting temperatures.... more
