Alcohol-related liver disease: mechanism could form basis for development of new therapies
Medicine & Science Alcohol-related liver disease is among the most common causes of morbidity and mortality worldwide. Due to an incomplete understanding of the factors contributing to disease development, liver transplantation is still the only available cure. A team led by Tim Hendrikx from MedUni Vienna's Department of Laboratory Medicine has now uncovered a new mechanism that plays an important role in the progression of the disease.

Elk and bison would find enough space in Germany - if they make it to us
Elk and bison would find enough space in Germany - if they make it to us
Large herbivores such as bison and elk played an important role in our oceans systems for thousands and millions of years, but in this country they were driven out of many areas by humans in the past and became extinct in Germany. For several years, both species have been spreading westward out of Eastern Europe, and sporadic sightings of elk and bison have been made in eastern Germany.

Satellite Data Shows Sustained Severe Drought in Europe
Satellite Data Shows Sustained Severe Drought in Europe
By Falko Schoklitsch Europe lacks groundwater - a lot of groundwater. The continent has already been suffering from a severe drought since 2018. This is confirmed by satellite data analysed at the Institute of Geodesy at TU Graz. Europe has been experiencing a severe drought for years. Across the continent, groundwater levels have been consistently low since 2018, even if extreme weather events with flooding temporarily give a different picture.

Actin affects the spread of cancer in several ways
The transport of molecules along the cell's skeleton plays a role in cancer metastasis, Freiburg researchers show Metastases occur when cancer cells leave a primary tumor and spread throughout the body. For this, they have to break connections with neighboring cells and migrate to other tissues. Both processes are promoted by signalling molecules released by the cancer cells, which thereby increase the malignancy of tumors.

Attitude towards science depends on what you think you know, rather than what you actually know
Attitude towards science depends on what you think you know, rather than what you actually know
Survey of over 2,000 adults in the UK identifies potential pitfalls of science communication. Why do people hold highly variable attitudes towards well-evidenced science? For many years researchers focused on what people know about science, thinking that -to know science is to love it-. But do people who think they know science actually know science?

Feature: Preserving endangered languages as 3D shapes
Half of the world's languages are endangered and more than a thousand are expected to be lost in coming decades. A team at UCL is using animation software to preserve these languages in an entirely new way. It's estimated that there are over 7,000 documented languages spoken across the world. Yet around half of these languages are endangered.

Randomness in Quantum Machines Helps Verify Their Accuracy
In quantum computers and other experimental quantum systems, information spreads around the devices and quickly becomes scrambled like dice in a game of Boggle. This scrambling process happens as the basic units of the system, called qubits (like computer bits only quantum) become entangled with one another; entanglement is a phenomenon in quantum physics where particles link up with each other and remain connected even though they are not in direct contact.

Gun control measures associated with reduced police use of force
As police departments and activists look for strategies to reduce excessive use of force by police, new research from the University of Michigan shows limited data, lack of transparency and irregular implementation of reforms make it difficult to determine which approaches are effective. The Black Lives Matter movement, which gained worldwide attention after the May 2020 death of George Floyd, has raised awareness of the police brutality and systematic racism that overwhelmingly affects Black Americans.

Look on the Bright Side of Earth
Why do Earth's hemispheres look equally bright when viewed from space? Weizmann Institute scientists offer a solution to this 50-year-old mystery When looking at the Earth from space, its hemispheres - northern and southern - appear equally bright. This is particularly unexpected because the Southern Hemisphere is mostly covered with dark oceans, whereas the Northern Hemisphere has a vast land area that is much brighter than these oceans.
