A groundbreaking genetic screening tool for human organoids

Many of the fundamental principles in biology and essentially all pathways regulating development were identified in so-called genetics screens. Originally pioneered in the fruit fly Drosophila and the nematode C. elegans, ...

Molecular compass for cell orientation

Plants have veins that transport nutrients throughout their whole body. These veins are organized in a highly ordered manner. The plant hormone auxin travels directionally from cell-to-cell and provides cells with positional ...

Bioenergy research team sequences miscanthus genome

An international research team has sequenced the full genome of an ornamental variety of miscanthus, a wild perennial grass emerging as a prime candidate for sustainable bioenergy crops.

Lab tests show risks of using CRISPR gene editing on embryos

A lab experiment aimed at fixing defective DNA in human embryos shows what can go wrong with this type of gene editing and why leading scientists say it's too unsafe to try. In more than half of the cases, the editing caused ...

Truncated immune system receptors may regulate cellular activity

MIT Media Lab researchers have discovered that shortened versions of immunity-related protein receptors, long written off as incomplete and therefore nonfunctional, can bind with their natural counterparts on the cell membrane ...

A new RNA catalyst from the lab

Enzymes enable biochemical reactions that would otherwise not take place on their own. In nature, it is mostly proteins that function as enzymes. However, other molecules can also perform enzymatic reactions—for example ...

Coronaviruses are masters of mimicry, new study finds

Coronaviruses are adept at imitating human immune proteins that have been implicated in severe COVID-19 disease, a study from researchers at Columbia University Vagelos College of Physicians and Surgeons has found.

Yeast study yields insights into longstanding evolution debate

In the past two decades, researchers have shown that biological traits in both species and individual cells can be shaped by the environment and inherited even without gene mutations, an outcome that contradicts one of the ...

How stem cells choose their careers

"What do you want to be when you grow up?" is a question it seems like every child gets asked. A few precocious ones might answer "a doctor" or "an astronaut," but most will probably smile and shrug their shoulders. But well ...
