The imbalance of energy on Earth is the most important metric in order to gauge the size and effects of climate change, according to a new study.

Satellite-tracking of the largest fish in the ocean offered insight into their migratory and feeding behavior, but their breeding grounds are still a mystery.

In just a few hours, scientists can tell which variant has infected a COVID-19 patient -- a critical task that can potentially influence treatment decisions but takes days or weeks at most medical centers.

Using artificial intelligence, researchers have discovered a new family of sensing genes in enteric bacteria that are linked by structure and probably function, but not genetic sequence. The findings offer a new way of identifying the role of genes in unrelated species and could lead to new ways to fight intestinal bacterial infections.

Sniffing or licking other dogs' genitalia -- the common site of Canine Transmissible Venereal Tumour -- can spread this unusual cancer to the nose and mouth.

Schiff base-metal complexes exhibit promising antibacterial and antioxidant properties. However, conventional methods for their preparation can be time-consuming. To reduce the reaction time and improve the quality and quantity of the products, researchers designed a new synthesis technique that uses microwave irradiation and methanol for the preparation of amino acid Schiff base copper complexes in just 10 minutes. The resulting products exhibit desirable properties, such as mild antioxidant activity and antibacterial activity against Escherichia coli.

Researchers have developed a rapid and effective antibody detection method for SARS-CoV-2 that is minimally invasive and applicable in resource-limited settings. Their methodology, which uses a patch sensor containing porous microneedles and a paper-based immunoassay, could have far-reaching implications for the blood-free detection of COVID-19 and many other infectious diseases.
