Hitting reset to start a new embryo

New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits "reset" so that the newly formed embryo can develop according to its own genetic program. The study was published July 17 in Nature.

Criticism with care is more persuasive, finds study

When unethical behavior is criticized, demands are often met with defensiveness and denial. How can we overcome this reaction? New research from the University of Zurich demonstrates that criticism is more persuasive when ...

How one of nature's most fundamental molecules forms

Life runs on ribosomes. Every cell on Earth needs ribosomes to translate genetic information into all the proteins needed for the organism to function—and to in turn make more ribosomes. But scientists still lack a clear ...

Missing link explains mRNA delivery in brain cells

Brain cells manufacture proteins in every corner, including their long branches. Neurons missing this ability cause severe neurological disorders like disability and epilepsy. The groups of Marino Zerial, Max Planck Institute ...

A protein hidden in plain sight helps cells time their escape

When a cell is getting ready to divide, it needs to duplicate its DNA, which is divided among its chromosomes, and arrange the chromosomes so that each new cell gets one complete set. If the chromosomes get sorted incorrectly, ...

Humans vs. bacteria: Differences in ribosome decoding revealed

Scientists at St. Jude Children's Research Hospital revealed that human ribosomes decode messenger RNA (mRNA) 10 times slower than bacterial ribosomes, but do so more accurately. The study, published today in Nature, used ...

New nanoparticles can perform gene-editing in the lungs

Engineers at MIT and the University of Massachusetts Medical School have designed a new type of nanoparticle that can be administered to the lungs, where it can deliver messenger RNA encoding useful proteins.
