Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery. This approach, called neoadjuvant therapy, helps to reduce the size of the tumor to facilitate breast-conserving surgery, and can even eradicate the tumor, leaving few...
Regular use of a common type of medication, such as aspirin and ibuprofen, significantly improves survival for a third or more patients with head and neck cancer, a new study led by UC San Francisco has found. Non-steroidal anti-inflammatory drugs,...
Yale researchers have identified a drinkable cocktail of designer molecules that interferes with a crucial first step of Alzheimer's and even restores memories in mice, they report Jan. 2 in the journal Cell Reports. The binding of amyloid beta peptides...
Using machine learning, a team of Western computer scientists and biologists have identified an underlying genomic signature for 29 different COVID-19 DNA sequences. This new data discovery tool will allow researchers to quickly and easily classify a deadly virus like...
In satellite photos of the Earth, clouds of bright green bloom across the surface of lakes and oceans as algae populations explode in nutrient-rich water. From the air, the algae appear to be the primary players in the ecological...
CRISPR-based genetic screens have helped scientists identify genes that are key players in sickle-cell anemia, cancer immunotherapy, lung cancer metastasis, and many other diseases. However, these genetic screens are limited in scope: They can only edit or target DNA....
Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to...
The toxin can block the use of important amino acids required by the bacteria to produce essential proteins needed for survival. An international team of researchers, led by Durham University, UK, and the Laboratory of Molecular Microbiology and Genetics/Centre Integrative...
Scientists at ETH Zurich and the South African company Strait Access Technologies are using 3-D printing to produce custom-made artificial heart valves from silicone. This could help meet an aging population's growing demand for replacement heart valves. The human heart has four...
Scientists have created the first retroviral CRISPR-Cas9 gene editing library to explore the regulation of mouse T cells, which are key cells in the immune system. Researchers from the Wellcome Sanger Institute and their collaborators have mapped the most...
Scientists at Washington University School of Medicine in St. Louis have developed a new imaging agent that could let doctors identify not only multiple types of tumors but the surrounding normal cells that the cancer takes over and uses...
