Phys.org / 'Flying focus' laser overcomes key limitation in plasma-based particle accelerators

In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible ...

Medical Xpress / Two-stage process helps metastatic cancer cells hide, then multiply in the lungs

Most cancer deaths are caused not by the initial tumor but by the spread of cancer cells to distant organs in the process called metastasis. Since it occurs at the cellular level, the earliest stages of metastasis are difficult ...

Phys.org / Butterfly ranges shift worldwide amid climate change, with most species expanding their reach

A global analysis of range-shift records for 1,758 butterfly species—10% of known butterfly species—found that 80% had expanded their range and that 79% of all recorded range shifts were linked to climate change and extreme ...

Medical Xpress / Study reveals prefrontal cortex can hinder learning more efficient behaviors

The prefrontal cortex, a brain region long associated with learning more flexible behaviors, can sometimes block the ability to think outside the box, a new study in mice shows. The finding by biologists at Emory University ...

Phys.org / Reduced gravity pushes people toward simpler movement patterns, experiments suggest

From reaching for a cup of coffee to tying your shoelaces, gravity shapes nearly all human movement. So how do our bodies react when that familiar force begins to change? Texas A&M University researchers are exploring the ...

Phys.org / Gut cells may measure hunger by how watery their insides become

Researchers led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered that the natural turnover of gut cells in fruit flies depends on how much food the flies get, rather than on ...
