| Beyond sci-fi: Manipulating liquid metals without contact Posted: 07 Feb 2022 02:29 PM PST Research inspired by Terminator 2's shape-shifting, liquid metal robot sees liquid-metal electrical conductors manipulated in mid-air without contact. The liquid wires can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares using a small 'triggering' voltage and a magnet. The new technology has potential application in advanced manufacturing and dynamic electronic structures, augmenting other non-contact manipulation technologies such as acoustics or optical tweezers. |

| New radar technology records Antarctic glaciers losing ice faster than ever documented before Posted: 07 Feb 2022 12:56 PM PST Unprecedented mass loss from three Antarctic glaciers could signal global climate trouble ahead, a researcher warns. A multinational collaboration is using an advanced remote imaging system to document the Pope, Smith and Kohler glaciers with clarity and completeness never achieved before. |
| As tectonic plates pull apart, what drives the formation of rifts? Posted: 07 Feb 2022 12:56 PM PST At the boundaries between tectonic plates, narrow rifts can form as Earth's crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force the land apart? Or is a rift just a rip, created mainly by the pulling motion of tectonic plates that are drifting away from each other? A study explores these questions and sheds new light on how this process works. |
| Poor sleep can triple risk for heart disease Posted: 07 Feb 2022 12:56 PM PST Individual aspects of poor sleep can be detrimental to heart health. But if you combine them, the risk of heart disease can increase by as much as 141 percent. |
| How do pathogens learn to be pathogens? Partnerships between microbes leading to human disease Posted: 07 Feb 2022 10:58 AM PST New research discovered that the fungus Rhizopus fights back against soil predators and human immune cells by partnering with a bacteria called Ralstonia in a two-way partnership. |
| Gene regulation in mammals offers clues connecting pregnancy and cancer metastasis Posted: 07 Feb 2022 10:58 AM PST In many mammals including humans, the placenta invades the wall of the uterus during pregnancy in the same way that cancer cells invade surrounding tissues. Using genomic sequences and gene expression information, researchers were able to predict specific signaling proteins that drive the expression of genes that decrease the susceptibility of invasion in human cells. Using a custom fabricated bio chip, the researchers confirmed that these predicted proteins did in fact decrease the invasion of both cancer and placental cells. |
| Posted: 07 Feb 2022 09:48 AM PST Researchers report that a prospective study of 14 infants and children demonstrated that convalescent plasma -- a blood product collected from patients recovered from infections with the coronavirus (SARS-CoV-2) that causes COVID-19 -- was safe in high risk children infected with or exposed to the virus. |
| In mice, mothers with metabolic syndrome can 'turn on' offspring’s liver disease Posted: 07 Feb 2022 09:48 AM PST An imprinted gene associated with development of non-alcoholic fatty liver disease (NAFLD) is switched on in mice who nurse from mothers with metabolic syndrome, even when those mice are not biologically related. |
| The frogs of Baja California: Scientists assess amphibian disease Posted: 07 Feb 2022 09:48 AM PST Biologists from Southern and Baja California have published the first major account of the amphibian disease chytridiomycosis in the Mediterranean region of Baja California. Their results indicate that the disease is more prevalent on the peninsula than in similar areas of Southern California. |
| Study shows life-saving benefit of baricitinib for ventilated COVID patients Posted: 07 Feb 2022 09:48 AM PST Critically ill COVID-19 patients on a mechanical ventilator or extracorporeal membrane oxygenation (ECMO) lived more often when randomized to receive baricitinib. Doctors call this drug 'bari,' and receiving the pill once a day for up to 14 days yielded one of the largest a survival advantages seen yet in the COVID pandemic, according to a new study. |
| New personalized test for an earlier and more accurate prediction of cancer relapse Posted: 07 Feb 2022 09:48 AM PST Researchers have developed a new protocol for monitoring acute lymphoblastic leukemia (ALL), the most common cancer in children, to inform more effective treatment strategies and detect disease recurrence. The personalized mediator probe PCR (MP PCR) uses multiple genomic cancer cell markers in a single assay and is simpler than current techniques. It improves monitoring clonal tumor evolution to detect a relapse sooner and avoid false negative results. |
| COVID-19 infections increase risk of heart conditions up to a year later, study finds Posted: 07 Feb 2022 09:48 AM PST An analysis of federal health data indicates that people who have had COVID-19 are at increased risk of developing cardiovascular complications within the first month to a year after infection, according to researchers. |
