Most Americans should get screened for colorectal cancer beginning at age 45 instead of age 50, according to new recommendations from the U.S. Preventive Services Task Force, which includes UVA Health's Li Li, MD, PhD, MPH. This recommendation applies to Americans without symptoms who do not have a history of colorectal polyps or a personal or family health history of genetic disorders that increase the risk of colorectal cancer.

A study of more than 1,000 demographically representative participants found that about 22 percent of Americans self-identify as anti-vaxxers, and tend to embrace the label as a form of social identity.

A team led by Carnegie's Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic and energy devices with enhanced properties that exceed those of the "normal" cubic form of silicon used today.

A new drug reduced tumor size in patients who have lung cancer patients with a specific, disease-causing change in the gene KRAS, a study found.

In a new Nature Communications study, researchers from BU's Microbiome Initiative discovered that providing microbial communities with a broader variety of food sources didn't increase the variety of microbial species within their experiments, but more food did fuel more microbial growth. The team's ultimate goal is to learn how to direct microbiome behavior through environmental molecules like food sources.

A new experiment offers the cleanest proof yet for magnetism-driven transitions of metals to insulators.

A team of BU biologists revealed, for the first time, that it is possible to accurately predict the abundance of different species of soil microbes in different parts of the world.

New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.

It has recently become prominent in Mexico and, similarly to other variants, presents a mutation in the Spike protein of the coronavirus. The "Mexican variant" was identified by a research group of the University of Bologna

Results from the Phase II cohort of the CodeBreaK 100 study showed that treatment with the KRAS G12C inhibitor sotorasib achieved a 37.1% objective response rate and 12.5 months median overall survival in previously treated patients with KRAS G12C-mutated non-small cell lung cancer (NSCLC), according to researchers from The University of Texas MD Anderson Cancer Center.

A new study shows that substantial amounts of carbon dioxide were released during the last millennium because of crop cultivation on peatlands in the Northern Hemisphere.

Accurate soft tissue measurements are critical when making reconstructions of human ancestors, a new study from the University of Adelaide and Arizona State University has found.

New research finds that increases in monsoon rainfall over the past million years were linked with increases in atmospheric CO2 and the import of moisture from the southern hemisphere, which suggests stronger rains in the future as CO2 levels rise.

The new drug sotorasib reduces tumor size and shows promise in improving survival among patients with lung tumors caused by a specific DNA mutation, according to results of a global phase 2 clinical trial led by Washington University School of Medicine in St. Louis. The drug is designed to shut down the effects of the mutation, which is found in about 13% of patients with lung adenocarcinoma, a common type of non-small-cell lung cancer.

Researchers from the University of Illinois Urbana-Champaign designed a laboratory exercise to teach students how to use micropipettes, through remote learning, using at-home kits.

Researchers in Lund, Copenhagen and Norwich have shown that harmful mutations present in the DNA play an important - yet neglected - role in the conservation and translocation programs of threatened species.

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. University of Groningen physicist, Anupam Mazumdar, describes how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications.

As meat-eating continues to increase around the world, food scientists are focusing on ways to create healthier, better-tasting and more sustainable plant-based protein products that mimic meat, fish, milk, cheese and eggs.

A phase III clinical trial led by an investigator at the Medical University of South Carolina found that a novel four-month regimen was just as effective at treating tuberculosis as the standard six-month regimen. The findings are reported in the May 6, 2021 New England Journal of Medicine.

St. Jude immunologists are researching how effector and killer T cells can be controlled to destroy cancer cells that resist treatment.
