Glaciers in West Antarctica are moving more quickly from land into the ocean, contributing to rising global sea levels. A 25-year record of satellite observations has been used to show widespread increases in ice speed across the Getz sector for the first time, with some ice accelerating into the ocean by nearly 50%.
Researchers including Göttingen University discover biologically-relevant organic molecules in fluid inclusions It is generally accepted that the earliest life forms used small organic molecules as building materials and energy sources. However, the existence of such components in early habitats on Earth had not been proven to date.
A potential new treatment to protect immunosuppressed patients from human cytomegalovirus ( HCMV ) has been discovered by scientists at the University of Cambridge. Their study shows that certain epigenetic inhibitors expose and help to destroy dormant HCMV infections, which often reactivate to cause serious illness and death in these vulnerable groups.
Reddit shows people with kidney stones have been less likely to seek treatment during pandemic
FINDINGS According to an examination of posts on Reddit, the pandemic has had a significant effect on the management of kidney stone disease. Researchers from the department of urology at the David Geffen School of Medicine at UCLA used computational analysis and other techniques to explore unfiltered discussions related to kidney stones in real time on the website's discussion forums.

Recognition, belief and an emotional response to disinformation are key factors in it being shared on social media, report finds
Fake news stories are more likely to be believed and consequently shared on social media if readers think they have seen them before, research suggests. Academics at Cardiff University's Crime and Security Research Institute say their report offers insights into the reasons why seemingly outlandish claims on social media can gain traction.

COVID-19 infection in pregnancy not linked with stillbirth or baby death
COVID-19 infection in pregnancy is not associated with stillbirth or early neonatal death, according to a new study. However, the research, from more than 4,000 pregnant women with suspected or confirmed COVID-19, also found women who had a positive test had a higher risk of premature birth. The research, led by Imperial College London and published in the journal Ultrasound in Obstetrics and Gynaecology today , used data from the UK and the USA.

Drug-checking services with substance analyses help reduce the risks associated with drug use. A study commissioned by the FOPH shows that this service helps protect users from overdoses and adverse reactions to adulterants. The study also underlines the potential of drug checking for identifying vulnerable individuals at an early stage and for monitoring the drug market.
New Material is Next Step Toward Stable High-voltage Long-life Solid-state Sodium-ion Batteries
A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity-a performance unmatched by other solid-state sodium batteries to date.

How a single cell slime mold makes smart decisions without a central nervous system Having a memory of past events enables us to take smarter decisions about the future. Researchers at the Max-Planck Institute for Dynamics and Self-Organization (MPI-DS) and the Technical University of Munich (TUM) have now identified how the slime mold Physarum polycephalum saves memories - although it has no nervous system.
No Certainty on Origin of Human Remains Found on Campus
Freie Universität Berlin, Max Planck Society, and Berlin State Monuments Office present the findings of their investigation into human remains found on Freie Universität land No 033/2021 from Feb 23, 2021 At an official public information event, experts from Freie Universität Berlin, the Max Planck Society, and the Berlin State Monuments Office ( Landesdenkmalamt Berlin ) presented the findings of their investigation into human remains found on the grounds of Freie Universität Berlin in recent years.

Mutable: Graz Researchers Decode Genome of Two Cichlid Species
Nature and man must constantly adapt to new living conditions. A research team from Graz has investigated how this is done and which genes play an important role in this process using the model system of the Great Lakes of East Africa. Global warming, environmental change, dried up food sources: nature and man must constantly adapt to new living conditions.

Twin atoms: A source for entangled particles
Quantum experiments that could previously only be performed with photons are now also possible with atoms: Beams of entangled atoms have been produced at TU Wien (Vienna). Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects.

A digital twin of our planet is to simulate the Earth system in future. It is intended to support policy-makers in taking appropriate measures to better prepare for extreme events. A new strategy paper by European scientists and ETH Zurich computer scientists shows how this can be achieved. To become climate neutral by 2050, the European Union launched two ambitious programmes: " Green Deal " and " DigitalStrategy ".
Recerca Huntington's disease is caused by a mutation in the Huntingtin gene (HTT), which appears in adults and features motor, cognitive and psychiatric alterations. The origin of this disease has been associated with the anomalous functioning of the mutated protein: mHTT, but recent data showed the involvement of other molecular mechanisms.
"Good bacteria" in breast milk changes over time
Scientists discover complex and dynamic bacterial ecosystem in human breast milk using genomic technology pioneered for the International Space Station The cocktail of beneficial bacteria passed from mother to infant through breast milk changes significantly over time and could act like a daily booster shot for infant immunity and metabolism.

How embracing uncertainty can help policymakers during a pandemic
Since the onset of the COVID-19 pandemic, policymakers have been forced to make decisions in the face of uncertainty. But key policy questions-like how best to reduce viral transmission while avoiding bad economic consequences of lockdowns-rarely come with definitive answers. Instead, quantitative models present a range of outcomes that could occur under different subjective inputs into the model constructions.

Vaccination has been linked to a substantial reduction in the risk of Covid-19 admissions to Scotland's hospitals, landmark research suggests. The study is the first to describe across an entire country the effect of the Pfizer and Oxford-AstraZeneca jabs in the community on preventing severe illness resulting in hospitalisation.
High fructose diets could cause immune system damage
New research led by Swansea University in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in the sugar fructose might prevent the proper functioning of peoples' immune systems in ways that has, until now, largely been unknown.

Brenner Base Tunnel as a Lighthouse Project: Tunnels to become CO2-neutral energy suppliers
Research association led by TU Graz wants to use the heat contained in the discharged tunnel water to supply energy to entire city districts. As part of the FFG programme "City of the Future", a sustainable concept for the city of Innsbruck is being developed. Additional Images for download at the end of the text After completion in about ten years, the Brenner base tunnel is expected to provide relief for transit traffic between Italy and Austria.

By using 3D aerosol jet-printing to put perovskites on graphene, scientists at EPFL have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health hazard of medical imaging devices. Since Wilhelm Röntgen discovered them in 1895, X-rays have become a staple of medical imaging.
