How information might be retrieved from a black hole

There may be a way to retrieve a bit of information from inside a black hole. A team of physicists from the California Institute of Technology theorizes that the information can be gleaned by using Hawking radiation exiting the black hole and quantum teleportation.


Crows seen making, using tools

New Caledonian crows create tools to help them forage for food. Scientists attached small cameras to the birds’ tail feathers and filmed them shaping, then using, a hook-shaped tool from a V-shaped stick to scoop out bugs and larvae from logs and underneath leaves. “Tool use is fairly rare in the animal kingdom, but manufacturing tools is exceedingly rare. There are very few animals, apart from humans, that actually manufacture anything that resembles a complex tool,” said Jolyon Troscianko, an author of the study published.

DNA disruption found in brain cancer study

Scientists have found a new way for cancer cells to form due to a disruption in DNA. The disruption causes the separation between two genetic areas to fall away, allowing a bit of DNA from one area into the other, where it triggers a growth gene, researchers say. Scientists discovered the process while studying brain tumor DNA.

Blocking molecule in uterus may delay or stop premature labor

Premature labor may be delayed or even stopped by blocking a molecule in the uterus, according to a new study. Researchers looked at the molecule TRPV4 in mice and found that blocking it prevented premature labor.
