Researchers Identify Novel Long-Tongued Fly Species

Multiple prestigious US biomedical research awards have rarely or never been granted to a scientist with Asian ancestry, illustrating racial bias within American research societies and institutions, a researcher argues.

First, the genetically engineered cells became CD8⁺ killer T cells that wiped out his leukemia. Then they transformed into a stable population of CD4⁺ helper T cells that continue to circulate in his body.

When coated with positively charged particles, the bacteria shuttled antigens out of tumors and activated the immune system, a study finds.

The genes are involved in pacing the development of inhibitory and excitatory neurons. An imbalance in these two types of signaling is thought to play a role in autism.

Only half of volunteers deliberately exposed to SARS-CoV-2 developed an infection. None developed serious symptoms, paving the way for further challenge trials.

Scientists warn that climate change–induced early flowering could have negative effects on wildlife, agriculture, and gardening.

A new study of tree biodiversity estimates that Earth boasts 14 percent more tree species than previous efforts have identified.

In work that has not yet been peer-reviewed, researchers present evidence that microbes can and do live inside the venom glands of several dangerous species. It remains unclear whether they’re to blame for infections linked to bites.

Data from mouse models for mild coronavirus infections and human tissue samples offer further evidence that it doesn’t take a severe infection—or even infection of brain cells at all—to cause long-term neurological symptoms.
