With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Beyond The Scientist’s coverage of COVID-19’s molecular underpinnings were many other stories highlighting the advances made in scientists’ understanding of the biology of cells.

Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

A wiring map diagrams more than half a million neuronal connections in the first complete connectome of Drosophila and holds clues about which brain architectures best support learning.

To understand how memories are formed and maintained, neuroscientists travel far beyond the cell body in search of answers.

Data from postmortem brain tissues adds to the evidence that inflammation is associated with autism.

At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

The single-celled fungus allows researchers to study Alzheimer’s, Parkinson’s, ALS and other brain diseases with unparalleled speed and scale.

This year’s crop of winning products features many with a clinical focus and others that represent significant advances in sequencing, single-cell analysis, and more.

One warning came in black-and-white in 1993: A U.S. Congressional Office of Technology Assessment report projected that releasing 100 kilograms of aerosolized anthrax spores upwind of the U.S. capital could kill between 130,000 and 3 million people-a lethality at least matching that of a hydrogen bomb. Last year, a U.S. Justice Department exercise revealed that discharging pneumonic plague in Denver could create 3,700 or more cases, with an estimated 950 or more deaths within a week.1 Then, acco
