| Time crystal in a quantum computer Posted: 30 Nov 2021 10:02 AM PST Researchers have created and observed a new phase of matter, popularly known as a time crystal. |
| Nonverbal social interactions – even with unfriendly avatars – boost cooperation Posted: 30 Nov 2021 07:14 AM PST Scientists used animated humanoid avatars to study how nonverbal cues influence people's behavior. The research offers insight into the brain mechanisms that drive social and economic decision-making. |
| Team builds first living robots that can reproduce Posted: 29 Nov 2021 12:50 PM PST Scientists have discovered a new form of biological reproduction -- and created self-replicating living robots. Made from frog cells, these computer-designed organisms gather single cells inside a Pac-Man-shaped 'mouth' -- and release Xenobot 'babies' that look and move like themselves. Then the offspring go and do the same -- over and over. |
| New discovery opens the way for brain-like computers Posted: 29 Nov 2021 09:27 AM PST Research has long strived to develop computers to work as energy efficiently as our brains. A study has now succeeded in combining a memory function with a calculation function in the same component. The discovery opens the way for more efficient technologies, everything from mobile phones to self-driving cars. |
| A new topological magnet with colossal angular magnetoresistance Posted: 24 Nov 2021 12:39 PM PST A new topological magnet with colossal angular magnetoresistance. Trillion percent change of resistance can be achieved in the new material by simply rotating the direction of spin. |
| AI used to optimize several flow battery properties simultaneously Posted: 23 Nov 2021 01:28 PM PST To find the right battery molecules, researchers have turned to the power of artificial intelligence to search through a vast chemical space of over a million molecules and optimize for several properties. |
| New method gives rapid, objective insight into how cells are changed by disease Posted: 23 Nov 2021 10:14 AM PST A new 'image analysis pipeline' is giving scientists rapid new insight into how disease or injury have changed the body, down to the individual cell. It's called TDAExplore, which takes the detailed imaging provided by microscopy, pairs it with a hot area of mathematics called topology, which provides insight on how things are arranged, and the analytical power of artificial intelligence to give, for example, a new perspective on changes in a cell resulting from ALS and where in the cell they happen, according to a cell biologist involved with the study. |
| Social stress key to population's rate of COVID-19 infection, study finds Posted: 23 Nov 2021 10:13 AM PST Mathematicians have analysed global COVID-19 data to identify two constants which can drastically change a country's rate of infection. |
| Virtual reality tool to be used in the fight against disease Posted: 23 Nov 2021 10:12 AM PST Science has the technology to measure the activity of every gene within a single individual cell, and just one experiment can generate thousands of cells worth of data. Researchers have now revolutionized the way this data is analyzed -- by using 3D video gaming technology. |
| Stereotypes in STEM fields start by age six Posted: 22 Nov 2021 02:27 PM PST The perception that boys are more interested than girls in computer science and engineering starts as young as age six, according to a new study. That may be one reason why girls and women are underrepresented in these STEM career fields. |
