The amazing travels of small RNAs

In most organisms, small bits of RNA play a key role in gene regulation by silencing gene expression. They do this by targeting and docking onto complementary sequences of gene transcripts (also RNA molecules), which stop ...

Artificial cells produce parts of viruses for safe studies

Scientists searching for better diagnostic tests, drugs or vaccines against a virus must all begin by deciphering the structure of that virus. And when the virus in question is highly pathogenic, investigating, testing or ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Cell removal as the result of a mechanical instability

Researchers at Kanazawa University report in the Biophysical Journal that the process of cell removal from an epithelial layer follows from an inherent mechanical instability. Moreover, the forces generated by an extruding ...

Bacteria perform mass suicide to defend their colony

A new study from researchers at Oxford University's Departments of Zoology and Biochemistry shows that warring bacteria will engage in suicidal attacks in vast numbers to take down competitors.

Enabling functional genomics studies in individual cells

Although the first complete sequence of the human genome was reported more than 15 years ago, the biological functions of large parts of the genome are not yet known. Scientists working in the field of functional genomics ...
