Coastal upwelling along the coast of California has become more variable than during nearly any period in the past 600 years. Black et al. used a 576-year tree ring record – [Read More]
19 Sep
Life is short for the heaviest elements. They emerge from high-energy nuclear collisions with scant time for detection before they break up into lighter atoms. Even et al. – [Read More]
19 Sep
Patients with advanced melanoma can survive longer after treatment with the immunotherapy drug ipilimumab. Kvistborg et al. show how this therapeutic antibody exerts its beneficial – [Read More]
19 Sep
When a bunch of fermions get together, they obey the Pauli exclusion principle: No two fermions can be in the same quantum state. The fermions populate the available states, starting – [Read More]
19 Sep
Experiments that produce null results face a higher barrier to publication than those that yield statistically significant differences. Whether this is a problem depends on how many – [Read More]

Transfused blood saves lives. Despite the widespread use of this critical resource, it is difficult to increase blood cell numbers outside of the body. By screening thousands of small – [Read More]
19 Sep
Voluntary movement requires a molecular conversation between nerves and muscles. This conversation occurs at the neuromuscular junction, a structure where nerves and muscle physically – [Read More]

Sepsis is a condition in which the body responds to infection with inflammation, which then spirals out of control. During sepsis, dead cells release histones, proteins normally found – [Read More]
19 Sep
Although cells in the body contain the same DNA content, they can display widely varying form and function among tissues. This comes about by differential gene regulation and by establishing – [Read More]
19 Sep
The bulding blocks of DNA, deoxynucleotide triphosphates, are synthesized by the enzyme ribonucleotide reductase (RNR). Its central role in DNA synthesis and its aberrant expression – [Read More]
19 Sep
Physicists have used cold atomic gases to simulate quantum phenomena that we normally associate with much more complex systems, such as solid-state materials. Because the properties – [Read More]
19 Sep
Magnetism is a commonly observed phenomenon in the macroscopic world, but its origins lie in the quirky quantum-mechanical property of electrons and certain nuclei known as spin. Recent – [Read More]
19 Sep
A brain area called the lateral habenula is involved in negative motivation and may thus play a role in depression. Shabel et al. investigated synaptic transmission in a brain – [Read More]
19 Sep
Bacteria have an adaptive immune system, called CRISPR, that identifies invading viruses through their DNA or RNA sequences and cuts them up (see the Perspective by Zhang and Sontheimer). – [Read More]
