Does China's research and development funding reach the right firms?

Chinese investments in research and development (R&D) have burgeoned since the turn of the century, increasing more than tenfold in absolute terms since 2000 and reaching a high of 2.4 percent of GDP in 2020. As the world's second biggest spender on R&D after the United States, China is certainly a force to be reckoned with on the global innovation landscape. Its fresh push toward innovation-led...

Understanding cooperation and conflict in plant symbionts

The traditional idea of symbiosis—long-term interactions between two organisms—is that the participants mutually benefit each other. However, researchers have debated whether the interests of the symbionts always line up with the hosts they inhabit, or whether genes that benefit symbionts might come at the expense of their hosts. A new study investigates this question through genomic...

Highest coral cover in central, northern Reef in 36 years

The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago. However, average coral cover in the southern region decreased due to ongoing crown-of-thorns starfish outbreaks. While the Reef experienced its fourth major bleaching event in the past seven years this year, it didn't...

Newly developed COVID-19 test detects and identifies specific variants with 100% accuracy

University of California, Irvine researchers have developed a COVID-19 test that detects and identifies specific SARS-CoV-2 variants with 100% accuracy. In a study, the RNA-encoded viral nucleic acid analytic reporter correctly determined the Alpha, Gamma, Delta, Epsilon and Omicron genetic mutations in nasopharyngeal clinical samples. This ability could enable healthcare providers to make...

NASA's PUNCH mission announces rideshare with SPHEREx and new launch date

NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will share a ride to space with NASA's Jet Propulsion Laboratory's Spectro-Photometer for the History of the Universe, Epoch of Re-ionization, and Ices Explorer (SPHEREx) mission. The missions will launch no earlier than April 2025 on a SpaceX Falcon 9.

Scientists identify key mechanism controlling skin regeneration

The outer layer of skin, the epidermis, is constantly turning over to replace dead or damaged cells throughout our lifetime. Skin stem cells need to continuously make decisions: either make more copies of themselves (self-renewal) or switch their fate towards differentiation. The molecular mechanisms controlling this process remain poorly understood. Now a research team has identified a molecular...
