| Ground-breaking study reveals dynamics of DNA replication ‘licensing’ Posted: 26 Jan 2022 01:55 PM PST A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. |
| Ancient ice reveals mysterious solar storm Posted: 26 Jan 2022 11:42 AM PST Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events. |
| Suitable growing regions for coffee, cashews, and avocados predicted to shift as Earth warms Posted: 26 Jan 2022 11:40 AM PST A new analysis predicts that, as climate change progresses, the most suitable regions for growing coffee arabica, cashews, and avocados will decline in some of the main countries that produce these crops. |
| Robot performs first laparoscopic surgery without human help Posted: 26 Jan 2022 11:39 AM PST A robot has performed laparoscopic surgery on the soft tissue of a pig without the guiding hand of a human -- a significant step in robotics toward fully automated surgery on humans. |
| Song sparrows shuffle and repeat to keep their audience listening Posted: 26 Jan 2022 09:24 AM PST Biologists have found an animal for the first time that communicates with the complexity of human language: song sparrows. According to a new study, male song sparrows memorize a 30-minute long playlist of their recently belted tunes and use that information to curate both their current playlist and the next one. The findings suggest that song sparrows deliberately shuffle and repeat their songs possibly to keep a female's attention. |
| Researchers provide insight into how the brain multitasks while walking Posted: 24 Jan 2022 12:10 PM PST New research turns the old idiom about not being able to walk and chew gum on its head. Scientists have shown that the healthy brain is able to multitask while walking without sacrificing how either activity is accomplished. |
| Scientists make first detection of exotic 'X' particles in quark-gluon plasma Posted: 24 Jan 2022 08:50 AM PST Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland. |
| Babies can tell who has close relationships based on one clue: Saliva Posted: 20 Jan 2022 11:07 AM PST Neuroscientists have identified a specific signal that young children and even babies can use to determine whether two people have a strong relationship and a mutual obligation to help each other: whether those two people kiss, share food, or have other interactions that involve sharing saliva. |
