Ocean sink for human-made carbon dioxide measured

Posted: 14 Mar 2019 12:16 PM PDT

Scientists have determined the amount of human-made carbon dioxide emissions taken up by the ocean between 1994 and 2007.

    

Study uncovers genetic switches that control process of whole-body regeneration

Posted: 14 Mar 2019 12:15 PM PDT

Researchers are shedding new light on how animals perform whole-body regeneration, and uncovered a number of DNA switches that appear to control genes used in the process.

    

Bacteria may help frogs attract mates

Posted: 14 Mar 2019 09:31 AM PDT

The role played by symbiotic microorganisms isolated from the skin of anurans has been discovered by researchers in Brazil.

    

Wild African ape reactions to novel camera traps

Posted: 14 Mar 2019 08:10 AM PDT

An international team of researchers analyzed video from remote camera-trap devices placed in ape-populated forests throughout Africa to see how wild apes would react to these unfamiliar objects. Responses varied by species, and even among individuals within the same species, but one thing was consistent throughout: the apes definitely noticed the cameras.

    

Brain wave stimulation may improve Alzheimer’s symptoms

Posted: 14 Mar 2019 08:10 AM PDT

By exposing mice to a unique combination of light and sound, neuroscientists have shown they can improve cognitive and memory impairments similar to those seen in Alzheimer’s patients.

    

Sea otters’ tool use leaves behind distinctive archaeological evidence

Posted: 14 Mar 2019 08:09 AM PDT

Researchers have analyzed the use by sea otters of large, shoreline rocks as ‘anvils’ to break open shells, as well as the resulting shell middens. The researchers used ecological and archaeological approaches to identify patterns that are characteristic of sea otter use of such locations. By looking at evidence of past anvil stone use, scientists could better understand sea otter habitat use.

    

Wolves lead, dogs follow — and both cooperate with humans

Posted: 14 Mar 2019 07:13 AM PDT

The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioral researchers, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.

    

Reversing the flow of time on a quantum computer

Posted: 14 Mar 2019 06:28 AM PDT

Researchers have developed an algorithm to simulate returning a particle briefly to the past. The results suggest new paths for exploring the backward flow of time in quantum systems. They also open new possibilities for quantum computer program testing and error correction.

    

Changes in rat size reveal habitat of ‘Hobbit’ hominin

Posted: 13 Mar 2019 08:47 AM PDT

A study of rat body sizes shifting over time gives a glimpse into the habitat of the mysterious hominin Homo floresiensis — nicknamed the ‘Hobbit’ due to its diminutive stature.
