Supernova explosions produce unstable isotopes, spreading them through space in the form of cosmic rays. Binns et al. used NASA's Advanced Composition Explorer spacecraft to – [Read More]
6 May
The transition between the Eocene and Oligocene periods was marked by distinct cooling. Because primate species are particularly susceptible to cold, this change in climate drove a – [Read More]
6 May
The growth of patterned objects usually requires a template to aid the positioning of multiple materials. Qiu et al. used the seeded growth of a crystallizable block copolymer – [Read More]
6 May
In the United States, the rich can expect to enjoy better health and a longer life than the poor. Despite policies directed at improving the health of both the young and the poor, there – [Read More]
6 May
In the gut, specialized cells either trigger inflammation or induce no immune response. Group 3 innate lymphoid cells (ILC3s), for example, balance tolerance to symbiotic gut microbes – [Read More]
6 May
Niemann-Pick type C (NPC) disease is a fatal neurological disorder caused by the deficiency of an enzyme involved in cholesterol storage. Although this disease was untreatable in the – [Read More]
6 May
Proteins are the workhorses of biology. Designing new, stable proteins with functions desirable in biotechnology or biomedicine remains challenging. Jacobs et al. developed – [Read More]
6 May
Cilia contain a well-ordered array of microtubule doublets along their length. A longstanding question in cilium structure and function is why the microtubule arrangement in cilia is – [Read More]
6 May
The eukaryotic cell nucleus provides a home for the genetic material and accessory proteins. As a physical entity, the nucleus also plays an important role in cell dynamics. Bustin – [Read More]
6 May
Regulatory information is stored both in DNA sequences and in the chromatin proteins that package the genome. The covalent modification of histones plays a critical role in signaling – [Read More]
6 May
SHANK3 is a widely expressed scaffolding protein that is enriched in postsynaptic specializations. In mutant mice, SHANK3 mutations cause autism-like behavioral changes and exhibit – [Read More]
6 May
Chemistry relies on encounters between reactive partners. Sometimes one of the partners changes shape during the wait, spoiling the desired outcome. Kim et al. designed a microfluidic – [Read More]
6 May
Many biological processes depend on detecting and responding to light. The response is often mediated by a structural change in a protein that begins when absorption of a photon causes – [Read More]
6 May
The complement system and microglia seek out and destroy unwanted cellular debris for the peripheral immune system as well as excess synapses in the developing brain. Hong et al. – [Read More]
6 May
Microorganisms have shaped Earth's oceans and atmosphere over billions of years. Ancient microbes left very little direct morphological evidence of their existence in the rock record, – [Read More]
6 May
General design principles for protein interaction specificity are challenging to extract. DNA nanotechnology, on the other hand, has harnessed the limited set of hydrogen-bonding interactions – [Read More]
6 May
A great mystery in the structure of the genetic code is the limitation on the number of unique transfer RNA (tRNA) molecules. Specifically, why are there only 20 amino acids, when 64 – [Read More]
6 May
The full range of deformation behavior of subduction zone faults that are responsible for great earthquakes and tsunamis is now clearer. Wallace et al. observed the heave of – [Read More]
