In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.

New research has identified key, naturally occurring biochemical components of a novel therapeutic food that is aimed at repairing malnourished children's underdeveloped gut microbiomes. The study also has identified the important bacterial strains that process these biochemical components. The findings may help guide treatment with a current food formulation and enable creation of new, more effective formulations in the future.

Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity between these cells.

Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it important to have methods that can selectively detect active proteases. Scientists have introduced a new class of protease-activity sensors: gold nanoparticles equipped with peptide DNA.

A protein that helps generate the force needed for single cells to move works differently in cells moving in groups, a new study shows.

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.

A previously mysterious small RNA molecule in mice is found to play a crucial role in gene expression, and may be the first identified member of a new class of regulatory RNAs.

In a comparative analysis across vertebrates of the many cell types in the retina -- mice alone have 130 types -- researchers concluded that most cell types have an ancient evolutionary history. Their remarkable conservation across species suggests that the retina of the last common ancestor of all mammals, which roamed the earth some 200 million year ago, must have had a complexity rivaling the retina of modern mammals.

Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.

In the future, a little saliva may be enough to detect an incipient cancer. Researchers have developed an effective way to interpret the changes in sugar molecules that occur in cancer cells.

It may soon be time to wake up and smell the lab-grown coffee made from cultured plant cells. But it's not clear whether drinks from this product replicate coffee beans' complex flavors. Now, a study found that some of the comforting aromas and tastes of a conventional cup of coffee could be reproduced by roasting and brewing coffee cell cultures.

Scientists have developed two new methods to create ordered carbon nanotube films with either a left- or right-handed chiral pattern.

Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.
