[Neuroscience] Antidepressants suppress DNA methylation

Some depressed patients show increased DNA methylation and decreased expression of a gene encoding BDNF, a secreted factor important for synaptic plasticity. In cells obtained from – [Read More]

[Nanomaterials] Brighter molybdenum layers

The confined layers of molybdenum disulphide (MoS2) exhibit photoluminescence that is attractive for optolectronic applications. In practice, efficiencies are low, presumably – [Read More]

[Evolutionary Biology] The downside of innovation

Evolutionary innovation allows a species to invade a new niche or environment. Generally, the emergence of adaptive traits is thought to lead to diversification. Support for this process – [Read More]

[Economics] Predicting unmeasurable wealth

In developing countries, collecting data on basic economic quantities, such as wealth and income, is costly, time-consuming, and unreliable. Taking advantage of the ubiquity of mobile – [Read More]

[Neuroscience] A census of neocortical neurons

Despite the importance of the brain's neocortex, we still do not completely understand the diversity and functional connections of its cell types. Jiang et al. recorded, labeled, – [Read More]

[Malaria] How malaria parasites infect the liver

Early in infection, malaria parasites establish themselves within hepatocytes in the liver. Inside these cells, the parasites occupy a so-called parasitophorous vacuole. Kaushansky – [Read More]

[Diabetes Immunotherapy] Tweaking T regulatory affairs

In patients with type 1 diabetes (T1D), immune cells destroy the insulin-producing beta cells of the pancreas. Consequent prolonged exposure to high blood sugar can damage organs and – [Read More]

[Genome Editing] Virally cleansing the pig genome

Transplants from pigs could be a solution to a shortage of human organs for transplantation. Unfortunately, porcine endogenous retroviruses (PERVs) are rife in pigs and can be transmitted – [Read More]

[Evolution] Evolutionary routes to blue

Animal coloration is vital for mate selection, camouflage, warning, and temperature regulation. The evolutionary pressure to get color right leads to tremendous variation among species. – [Read More]

[Geology] Salted away no longer?

Rock salt deposits are thought to be impermeable to fluid flow and so are candidates for nuclear waste repositories. Ghanbarzadeh et al. found that some salt deposits in the – [Read More]
