Scientists discover a new way of sharing genetic information in a common ocean microbe

From the tropics to the poles, from the sea surface to hundreds of feet below, the world's oceans are teeming with one of the tiniest of organisms: a type of bacteria called Prochlorococcus, which despite their minute size are collectively responsible for a sizable portion of the oceans' oxygen production. But the remarkable ability of these diminutive organisms to diversify and adapt to such...

DNA repair scheme gets closer look for cancer therapy

Researchers from Rice University and St. Jude Children's Research Hospital in Memphis, Tennessee, Have taken a close look at one of the ways cells repair broken strands of DNA and discovered details that could help make a particular enzyme a promising target for precision cancer therapy.

Researchers shed light on how exercise preserves physical fitness during aging

Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood.

Electrochemistry converts carbon to useful molecules

A chemistry collaboration has led to a creative way to put carbon dioxide to good—and even healthy—use: by incorporating it, via electrosynthesis, into a series of organic molecules that are vital to pharmaceutical development.

World’s Glaciers Are Melting Faster Than Expected New Study Warns

The world’s glaciers are shrinking and disappearing faster than scientists thought, with two-thirds of them projected to melt out of existence by the end of the century at current climate change trends, according to a new study. But if the world can limit future warming to just a few more tenths of a degree and fulfill international goals — technically possible but unlikely according...

Invasive rats transform reef fish behavior

Scientists have discovered for the first time that invasive rats on tropical islands are affecting the territorial behavior of fish on surrounding coral reefs. The new study shows that the presence of invasive black rats on tropical islands is causing changes in the territorial behavior of the jewel damselfish -- a herbivorous species of tropical reef fish that 'farm' algae in the branches of...

New quantum computing architecture could be used to connect large-scale devices

Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could be used to develop a large-scale network of quantum processors that could efficiently communicate with one another.

New approach successfully traces genomic variants back to genetic disorders

Researchers have published an assessment of 13 studies that took a genotype-first approach to patient care. This approach contrasts with the typical phenotype-first approach to clinical research, which starts with clinical findings. A genotype-first approach to patient care involves selecting patients with specific genomic variants and then studying their traits and symptoms; this finding...

DNA from archaeological remains shows that immigration to Scandinavia was exceptional during the Viking period

A new study based on 297 ancient Scandinavian genomes analysed together with the genomic data of 16,638 present day Scandinavians resolve the complex relations between geography, ancestry, and gene flow in Scandinavia -- encompassing the Roman Age, the Viking Age and later periods. A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially...
