Nature Communications, Published online: 01 November 2019; doi:10.1038/s41467-019-12862-7 Modern humans and Neanderthals coexisted in the Levant for tens of thousands of years before modern humans spread and replaced Neanderthals.

Termites Cannibalize Their Co-Workers for the Good of the Colony
Formosan subterranean termites, which are in the same genus as Asian subterranean termites. (Credit: Scott Bauer/USDA) (Inside Science) — The appetites of social termites extend to cannibalizing their co-workers after death. It's done for the greater good of the community. "Termites have a lot of strategies to keep the nest and the members of the colony clean," said Luiza Helena Bueno da Silva, a

Measles Leaves Us Vulnerable to Infections Both Old and New, Study Finds
A measles infection can wipe our immune system's memory and even leave us weaker against new infections. (Credit: infohay/Shutterstock) As the number of measles cases rises in the U.S, research reveals a new way the disease can leave patients vulnerable to future infections. Published in Science Immunology, an examination of measles patient immune systems showed that the disease didn't just leave

Creepy Music and Soviet Spycraft: The Amazing Life of Leon Theremin
Leon Theremin, also known as Lev Termen, demonstrates his musical instrument. (Credit: Wikimedia Commons) Imagine a UFO descending from the heavens, its round disk pale against the night sky. What sound does it make? You're likely imagining a keening whine in your head, like the howling of a haunted wind or the moans of a high-pitched ghost. That's the sound of the theremin, a musical instrument i

Simple injection of air proves successful in releasing child's tongue trapped in bottle, inspired by opening a wine bottle
A relatively simple injection of air has proved successful in releasing a 7-year-old boy's tongue that became entrapped in a juice bottle, says new research published in the latest edition of the European Journal of Anaesthesiology (the official journal of the European Society of Anaesthesiology).

Milk from teeth: Dental stem cells can generate milk-producing cells
Stem cells of the teeth can contribute to the regeneration of non-dental organs, namely mammary glands. According to a new study, dental epithelial stem cells from mice can generate mammary ducts and even milk-producing cells when transplanted into mammary glands. This could be used for post-surgery tissue regeneration in breast cancer patients.

Ynyslas, western Wales – a place made by climate change
Ynyslas, on the Cardigan Bay coast of Wales, is a place well-known for its extensive, shingle spit-fronted sand-dunes, its hinterland of estuarine saltmarsh-flats and, seaward, its golden sandy beach, complete with a several thousand year-old submerged forest. The place gets some 250,000 visitors a year. Taking all of those factors into account, and that Ynyslas is also a direct product of actual

Spacewatch: Nasa tests new imaging technology in space
Operation was designed to test technology that allows multiple targets to be studied at same time Nasa launched its experimental Fortis (Far-ultraviolet Off Rowland-circle Telescope for Imaging and Spectroscopy) telescope on 28 October from the White Sands missile range in New Mexico. The flight lasted 15 minutes, reached 162 miles (260km) in altitude, and then fell back to Earth – exactly as pla

This AI birdwatcher lets you 'see' through the eyes of a machine
It can take years of birdwatching experience to tell one species from the next. But using an artificial intelligence technique called deep learning, researchers have trained a computer to identify up to 200 species of birds from just a photo. This tool goes beyond giving the right answer to explain its thinking, in a way that even someone who doesn't know a penguin from a puffin can understand.

Mutated form of DNA repair protein may shed light on its role in preventing cancer
Researchers created a mutated version of RAD51, a DNA repair protein, to better understand its critical functions at key steps in the cell replication process during times of stress. This work may help cancer biology scientists better understand how cells protect DNA from damage during replication. Defects in this pathway may play a role in causing cancer and a better understanding of the process

Rare mutations drive cystic fibrosis in Caribbean
Cystic Fibrosis (CF) in the Caribbean is dominated by unusual gene mutations not often observed in previously studied CF populations, according to comprehensive genome sequencing led by physician-scientists at UC San Francisco and Centro de Neumología Pediátrica in San Juan. The rarity of the gene mutations observed in Caribbean CF patients highlights the fact that transformative new drugs for CF,

Study examines kidney injury in patients taking immunotherapy cancer medications
In patients taking immune checkpoint inhibitors as a treatment for cancer, 17% experienced acute kidney injury (AKI), 8% experienced sustained AKI, and 3% had potential immune checkpoint inhibitor-related AKI. Use of proton pump inhibitors, which are commonly used to treat stomach ulcers or acid reflux, was associated with a higher risk of experiencing sustained AKI.
