Today's gold standard for COVID diagnostics is qRT-PCR, but turnaround is typically more than a day. Newer assays using CRISPR enzymes require initial amplification of RNA, requiring special equipment not available in doctors' offices, workplaces, etc. By combining two different CRISPR-Cas enzymes -- Cas13 and Csm6 -- researchers have created a point of care diagnostic that provides results in under an hour, often in 20 minutes.

The more an academic discipline is perceived to require raw talent or 'brilliance' for success, the more both women and early-career academics feel professionally inadequate -- like 'impostors' -- finds a new study of U.S. academics by a team of psychology researchers.

Researchers have developed the largest and most comprehensive molecular map to date of the lung cancer subtype lung squamous cell carcinoma (LSCC). Their effort brings proteomic, transcriptomic, and genomic data together into a detailed 'proteogenomic' view of LSCC. Analysis of that data has revealed potential new drug targets, immune regulation pathways that might help the cancer evade immunotherapies, and even a new molecular subtype of LSCC.

Scientists have identified a naturally occurring mutation in nonhuman primates that closely resembles a rare neurodegenerative disease in people. The discovery could lead to the development of new therapies to treat Pelizaeus-Merzbacher disease and is the latest in a trove of discoveries made possible by a massive genomic database.

A gene called DOT1L appears to play a role in progression and severity of ovarian cancer, and inhibitors of the DOT1L enzyme may offer a new therapeutic approach for the disease, researchers say in a new study. The need is clear -- despite decades of work to develop new treatment modalities, the five-year survival of patients with advanced ovarian cancer is between 10 and 30 percent.

Wearable technology seems all poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists have delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as binaural hearing aids and earphones.

Researchers fabricated a brain-inspired highly scalable neuromorphic hardware by co-integrating single transistor neurons and synapses. Using standard silicon complementary metal-oxide-semiconductor (CMOS) technology, the neuromorphic hardware is expected to reduce chip cost and simplify fabrication procedures.

For a cell to grow and divide, it needs to produce new proteins. This also applies to cancer cells. Researchers have now investigated the protein eIF4A3 and its role in the growth of cancer cells. The study shows that by blocking or reducing the production of this protein, other processes arise that cause the growth and cell division of cancer cells to cease and eventually die.

A large clinical trial conducted worldwide shows that treating moderately ill hospitalized COVID-19 patients with a full-dose blood thinner reduced their need for organ support, such as mechanical ventilation, and improved their chances of leaving the hospital. However, the use of this treatment strategy for critically ill COVID-19 patients requiring intensive care did not result in the same outcomes.
