Competition between species drives the acquisition of diversity. Stuart et al. introduced a non-native anole lizard to natural experimental islands. In response, the original – [Read More]
24 Oct
The kinase PKD2 is activated in T cells of the immune system when a peptide antigen binds to and stimulates the T cell receptor (TCR). Navarro et al. found that low concentrations – [Read More]
24 Oct
Humans colonized the inhospitable high Andes at least 11.5 thousand years ago. Rademaker et al. unearthed evidence of hunter-gatherer occupation at heights of almost 4500 m – [Read More]
24 Oct
Viruses are master manipulators. The early stages of how flu viruses enter cells are very well understood, but Banerjee et al. describe a new wrinkle (see the Perspective by – [Read More]
24 Oct
Graphene has two distinct valleys in its electronic structure, in which the electrons have the same energy. Theorists have predicted that creating an asymmetry between the two valleys – [Read More]
24 Oct
Solar cells made from carbon-based polymers are helpfully flexible. However, there's been a frustrating tradeoff between cell stability and efficiency when converting solar power to – [Read More]
24 Oct
Understanding how proteins fold into well-defined three-dimensional structures has been a longstanding challenge. Increased understanding has led to increased success at designing proteins – [Read More]
24 Oct
The TOPK protein is found in a wide range of human cancers and is believed to promote tumor growth. Matsuo et al. developed a drug that can inhibit TOPK and be delivered by – [Read More]
24 Oct
Anaerobic bacteria can break down a range of organohalide pollutants. To do so, they use unusual reductive dehalogenase enzymes that remove the halogen ion from the molecule, making – [Read More]
24 Oct
Bacteria respond to a host of changing cues provided by their environment. Hol and Dekker review how microfluidic and nanofabricated devices can provide a platform to deliver different – [Read More]
24 Oct
Animation defines life, and the three-dimensional (3D) imaging of dynamic biological processes occurring within living specimens is essential to understand life. However, in vivo imaging, – [Read More]
24 Oct
Replication is highly regulated: Failure to copy any part of the genome or copying parts of it more than once can cause genome instability with potentially disastrous consequences. – [Read More]
24 Oct
At about 70°C, the material vanadium dioxide (VO2) switches from being a semiconductor to a metal. The switch happens so fast that it may be useful in electronic devices, – [Read More]
24 Oct
Many organic compounds are chiral: They manifest two distinct mirror-image variants, or enantiomers. Kinetic resolution can transform one enantiomer to a desired product while leaving – [Read More]
24 Oct
Working memory allows us to keep behaviorally relevant information in mind over a short period of time. Liu et al. trained mice to remember a smell for a short period after – [Read More]
24 Oct
An optimized ratio of male and females in a sexually reproducing population helps to generate the genetic diversity useful to a species in a changing world. Tanaka et al. studied – [Read More]
24 Oct
Marine ecosystems are under pressure. In a Perspective, Vincent and Harris highlight the particular problems of illegal, unregulated, and unreported fishing. In coastal areas worldwide, – [Read More]
24 Oct
The first feathers that evolved in early dinosaurs had a simple hairlike structure and probably served to insulate the body. How did these simple protofeathers evolve into the more – [Read More]
