Scientists have found evidence that a colossal cliff stretching thousands of kilometers across ancient North America may have exposed the heart of the Grand Canyon nearly a billion years before it was carved by the Colorado ...

States are moving faster and further than federal regulators to get kratom off store shelves, with some banning the herb outright while a pending federal rule targets only one of its chemicals.

A mysterious background of extremely low-frequency gravitational waves detected by networks of pulsars may carry information about events that began more than 13 billion years ago—including the formation of some of the first ...

Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum ...

From a fishing trawler in the Adriatic, Italian scientists gently release thousands of tiny octopuses in the hope of fighting an invasive crab species that has devastated local fisheries.

The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...

At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous ...

Cancer spreading beyond the primary tumor—a process known as metastasis—is responsible for at least two-thirds of cancer deaths. Drugs targeting metastatic progression have largely failed, in part because of the lack of predictive ...

Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...

A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth. Their study, published in the Proceedings of the National Academy of Sciences, describes the biosignatures ...

Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a ...

A new study from researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has uncovered a previously unknown consequence of viral infection: Too much RNA inside a cell can disrupt its ability ...
