Phys.org / Frog-cell 'neurobots' grow self-organized nervous systems and alter gene activity

Biobots, whose growing line of variants started with xenobots, are fascinating tiny self-powered living robots built exclusively using frog embryonic cells. Originally developed in the laboratories of Wyss Institute Associate ...

Phys.org / Location of reforestation projects has greater effect on climate than number of trees planted, study shows

In the fight against the climate crisis, countries are pinning great hope in reforestation projects. In a new study, ETH Zurich researchers show that the location in which reforestation is taking place is usually more important ...

Phys.org / Hunted by Neanderthals, giant elephants traveled hundreds of kilometers across ice-age Europe

Neumark-Nord in northeastern Germany was a lake landscape in the last interglacial period. It is rich in archaeological finds discovered during lignite mining. The area in Saxony-Anhalt is one of the most important European ...

Phys.org / Microbes in Antarctica survive the freezing and dark winter by living on air

Winter in Antarctica is long and dark. Temperatures remain well below freezing. In many places, the sun sets in April and does not rise above the horizon again until August. Without sunlight, photosynthetic life such as plants, ...

Phys.org / Gold nanoclusters could selectively recognize chiral biomolecules to help detect certain diseases

An extensive computational study by researchers from Finland's University of Jyväskylä predicts that gold nanoclusters could selectively recognize chiral biomolecules. This property may help in detecting certain diseases ...

Phys.org / Light-controlled hydrogel mimics soft human tissue for more realistic cell studies

For decades, lab-grown cells have been studied in materials that don't reflect the softness and flexibility of human tissue. Now researchers at the University of Colorado Boulder have developed a water-rich, Jell-O-like material ...

Phys.org / Structural modeling reveals phage proteins that manipulate bacterial immune signaling

The genomes of phages—viruses that infect bacteria—are largely composed of "dark matter": genes that encode proteins whose functions remain unknown. Less than four years ago, a team led by Prof. Rotem Sorek at the Weizmann ...

Phys.org / Personal change thresholds may explain why popular policies fail to spread

Why do widely supported solutions to major problems, such as climate change, so often struggle to gain real traction? A new study suggests that part of the answer lies in understanding why people resist change, and how the ...

Phys.org / Single-cell data reveal a cellular 'developmental hourglass' in vertebrate embryos

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late developmental stages but resemble one another more during mid-embryogenesis, a phenomenon known as developmental ...
