[Neuroscience] How will this molecule smell?

We still do not understand what a given substance will smell like. Keller et al. launched an international crowd-sourced competition in which many teams tried to solve how – [Read More]

[Cognition] Very clever bees use tools

One hallmark of cognitive complexity is the ability to manipulate objects with a specific goal in mind. Such “tool use” at one time was ascribed to humans alone, but then to primates, nex – [Read More]

[Vascular Disease] Faulty blood cells and heart disease

Recent studies have shown that elderly people's blood cells often harbor mutations in genes encoding certain epigenetic regulators. These mutations can lead to clonal expansion of the – [Read More]

[Extreme Astrophysics] Spinning up an extragalactic neutron star

Ultraluminous x-ray sources (ULXs) are strange objects in other galaxies that cannot be explained by conventional accretion onto stellar-mass objects. This has led to exotic interpretations, – [Read More]
