Shoring up the tissues that separate neurons and other brain cells from the circulatory system in fruit flies and mice can prolong life in the presence of a tumor.

Research on microneedle patches for vaccine delivery has grown in popularity in recent years, due to their exceptional compliance and low invasiveness.

As fires blanket growing swathes of the West, scientists are beginning to understand more about how their smoke affects the transmission and severity of COVID-19 and other illnesses, and how it differs from that of other types of air pollution.

The Scientist spoke with Rachel Zeig-Owens, the director of epidemiology for the World Trade Center Health Program, about what scientists have learned after two decades of studying illness and disease among survivors.

The SARS-CoV-2 variant was first detected in January, but its rising prevalence and potential resistance to vaccines has garnered it special attention from the World Health Organization.

A study suggests that mutations in the gene that encodes the T1R1/T1R3 taste receptor allowed primates that relied on insects for protein to transition to eating leaves and fruit.

The FDA granted the drug, called Aduhelm, accelerated approval earlier this summer in a process that’s since drawn scrutiny.

The dynamic behavior of a transcriptional activator can be used to specify the activity level of its target gene, a study suggests.

Different variants of the virus behind the COVID-19 pandemic are swapping chunks of genetic material, but it’s not yet clear what implications that may have for public health.

So far, more than 50 people have died of a febrile illness, though the cause isn’t clear.

Researchers studying rats claim to have found a novel connection between damage on one side of the brain and problems with the posture or movement of limbs on the opposite side of the body.
