From cell fat to cell fate
How does a cell "decide" what type of cell to become? The question of "cell fate" has been explored for decades now, especially in the context of stem cell biology, but there are still gaps in our understanding. For example, ...

Two-faced protein both inhibits and activates B cell receptor signaling
The rules to the kids' game "red light, green light" are easy to follow: red always means stop, and green always means go. But now, researchers from Japan have found that a key protein involved in B cell signaling acts as ...

Device directs sperm to 'go against the flow' to help infertility
The female genital tract can be a hostile environment for conception. Out of about 100 million sperm, only a few hundred make it to the fallopian tubes. Guided by a directional movement called rheotaxis, sperm cells swim ...

Best of Last Week – Solving Hawking's black hole paradox, a new form of ice, bad cholesterol may not be so bad
It was a good week for physics research as work by two teams of theorists working independently may have solved Stephen Hawking's black hole paradox. The first demonstrated that black holes are more complex than thought, ...
Compounds that suppress immune responses of plants discovered
A group of non-steroidal anti-inflammatory drugs (NSAIDs) may prove valuable for investigating the molecular mechanisms inherent in plant immunity, according to plant scientists at RIKEN. Their results may also help improve ...
