Gene therapy hailed as ‘medical magic wand’ for hereditary swelling disorder

Single-dose treatment transformed lives of patients with potentially deadly condition in first human trialA groundbreaking gene therapy has been hailed as a “medical magic wand” after the treatment transformed the lives of patients with a hereditary disorder that causes painful and potentially fatal swelling.Patients who took part in the first human trial of the therapy experienced a dramatic...

Fermentation revolution? Trash becomes treasure as bio-waste yields valuable acetone and isopropanol

In a major stride towards sustainable industrial fermentation, a team of researchers at Delft University of Technology (TU Delft) in The Netherlands, has unveiled pioneering advancements in the purification of isopropanol and acetone from the fermentation of waste gases. The study, published in the Journal of Chemical Technology and Biotechnology, introduces novel processes that promise to elevate...

Why don’t ants always fall for toxic bait? They may learn to avoid it

If you have an ant problem, toxic bait traps might seem like the perfect solution. There’s no spraying, no smooshing. After ants collect poison from the trap, they share it with the whole colony, wiping it out in one tidy, fell swoop. But toxic baits don’t always work as intended, and researchers have long puzzled over why. For Argentine ants, which are invasive in many parts of the...

First tetratomic supermolecules realized at nanokelvin temperatures

A team of experimentalists at the Max Planck Institute of Quantum Optics (MPQ) and theorists at the Chinese Academy of Sciences (CAS) has succeeded for the first time in populating and stabilizing a new type of molecule, so-called field-linked tetratomic molecules. These "supermolecules" are so fragile that they can only exist at ultracold temperatures. Their existence had long been suspected but...

When firms internalize political stigma

The Unite the Right Rally in Charlottesville, Va., in 2017 stigmatized local employers by creating the impression that strongly anti-diversity attitudes put on display by white supremacists were widespread in the community. Employers sought to counteract this "stigma by association" by dramatically increasing the extent to which they included pro-diversity language in their job advertisements.

Blood cell family trees trace how production changes with aging

Blood cells make up the majority of cells in the human body. They perform critical functions and their dysfunction is implicated in many important human diseases, from anemias to blood cancers like leukemia. The many types of blood cells include red blood cells that carry oxygen, platelets that promote clotting, as well as the myriad types of immune cells that protect our bodies from threats such...

Underwater unmanned vehicle missing under Doomsday Glacier

The unmanned underwater vehicle Ran has gone missing under a glacier in Antarctica. The vehicle, owned by the University of Gothenburg, is one of just three in the world that is used for research and has contributed to important knowledge about the so-called Doomsday Glacier.

High-tech aerial mapping reveals England's hedgerow landscape

Scientists have harnessed cutting-edge technology to produce the most comprehensive map of hedgerows across the length and breadth of England. The researchers at the UK Centre for Ecology & Hydrology (UKCEH) hope this innovative mapping will guide planting and restoration of these vulnerable habitats to support wildlife and mitigate climate change.

Trees struggle to 'breathe' as climate warms, researchers find

Trees are struggling to sequester heat-trapping carbon dioxide (CO2) in warmer, drier climates, meaning that they may no longer serve as a solution for offsetting humanity's carbon footprint as the planet continues to warm, according to a new study led by Penn State researchers.

Asian fishing cats caught snacking on chicks from tree-top nests

South Asian fishing cats were observed raiding bird nests in tall trees for the first time. This rare and highly unusual behavior was caught on motion cameras set up in tree canopies across northeast Bangladesh to survey bird colonies. Scientists hope this unexpected finding, published in the De Gruyter journal Mammalia, will help piece together the ecology of these elusive felines and contribute...

Green methanol for the circular economy: Researchers develop new catalyst

Researchers hope to produce the raw material methanol at the edge of a field or on the farm using renewable energy. In addition to wind or sun, water and CO2 would be needed to produce the raw materials for the green methanol process: carbon monoxide (CO) and hydrogen (H2), which react catalytically to form methanol.

First eROSITA sky-survey data release makes public the largest ever catalog of high-energy cosmic sources

The German eROSITA consortium has released the data for its share of the first all-sky survey by the soft X-ray imaging telescope flying aboard the Spectrum-RG (SRG) satellite. With about 900,000 distinct sources, the first eROSITA All-Sky Survey (eRASS1) has yielded the largest X-ray catalog ever published. The work is published in the journal Astronomy & Astrophysics.
