How climate change is altering the Earth’s rotation
When the Earth's ice masses melt, the way the planet rotates also changes. Researchers at ETH Zurich have now been able to show how climate change is altering the Earth's axis of rotation and the length of the day. The speed of rotation, which was hitherto mainly influenced by the moon, will now also depend much more on the climate.

Land protection initiatives reduced Amazon deforestation by up to 83%
A new analysis shows that land protection initiatives in the Brazilian Legal Amazon (BLA) reduced deforestation by up to 83% between 2000 and 2010. Such impressive results highlight the vital role of land protection policies in achieving ambitious goals, including the UN biodiversity target to protect 30% of the planet's surface by 2030 .

New insights into molecular mechanisms of cholera infection
New insights into molecular mechanisms of cholera infection
Researchers investigate the strong interaction of cholera toxin with a key ganglioside on the surface of intestinal cells Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells - more precisely, to certain "sugar lipids" (GM1 gangliosides, GM1) on the cell surfaces.

’Morning’ and ’evening’ detected on an exoplanet
The different atmospheric conditions of the 'morning' and 'evening' sides of a distant planet have been revealed by the James Webb Space Telescope. The atmospheres of exoplanets - those outside our Solar System - have been measured using powerful telescopes for some time. However, the atmosphere has always been treated as being the same all'over the planet.

AI Chatbots have shown they have an ’empathy gap’ that children are likely to miss
New study proposes a framework for "Child Safe AI" following recent incidents which revealed that many children see chatbots as quasi-human and trustworthy. When not designed with children's needs in mind, Artificial intelligence (AI) chatbots have an "empathy gap" that puts young users at particular risk of distress or harm, according to a study.

Is your work chair hurting your back?
Those trying to alleviate back pain after long hours of sitting at work may resort to painkillers, massage, acupuncture or heat therapy - but the solution may be as simple as switching out your office chair. Lower back pain during office work is often attributed to a lack of movement, with experts advising to take regular breaks from sitting as a temporary form of relief.

Lifestyle changes support reduction in the risk of dementia
There are currently around 1.8 million people living with dementia in Germany. Due to increased life expectancy, the proportion will continue to grow: based on data from the Federal Statistical Office, experts expect up to two million cases in 2033. For the first time, an intervention study was carried out to prevent mental decline in older GP patients.

Producing Hydrogen and Fertilizer at The Same Time
Producing Hydrogen and Fertilizer at The Same Time
This new concept could allow the needs of previously separate industries to be combined. A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer have so far been separate chemical processes.

SARS-CoV-2 infections have a long-term impact on the immune systemg
In a study recently published in the renowned journal "Allergy", a MedUni Vienna research team shows that COVID-19 leads to considerable long-term changes in the immune system, even in mild cases. The findings could help to better understand the long-term consequences of an infection with SARS-CoV-2.

The stirring of the deep waters of Lake Geneva revealed
Researchers discovered that deepwater renewal in Lake Geneva in wintertime is not only due to vertical mixing. Instead, strong currents coming from the lake's Petit Lac basin and nearshore zones of the Grand Lac play a vital role. In temperate lakes, deep vertical mixing, known as turnover, happens during winter.

How small lifestyle changes can improve teen mental health over time
A new study has revealed compelling evidence that small improvements in daily lifestyle choices can lead to improvements in high school students mental health. PhD candidate Scarlett Smout from the Matilda Centre writes about the results. Judging by  recent headlines  and  policy ideas , you might think screen time is the only lifestyle behaviour influencing teen wellbeing.

Autoantibodies Behind Lifelong Risk of Viral Infections
A new study shows that about two percent of the population develop autoantibodies against type 1 interferons, mostly later in life. This makes individuals more susceptible to viral diseases like COVID-19. The study, conducted by researchers together with a USZ team, is based on an analysis of a large collection of historical blood samples.

Caught in the Actinium
Key Takeaways Actinium is notoriously difficult to study and only available in small amounts. Researchers bound actinium with both a metal-trapping molecule and a protein to grow a crystal and reveal the compound's atomic structure. Scientists often use non-radioactive lighter elements to predict the chemistry of their radioactive heavier counterparts - and were surprised to find actinium behaved differently than expected based on their observations of its lighter counterpart, lanthanum.

Anesthesia drug induces unconsciousness
Propofol, a drug commonly used for general anesthesia, derails the brain's normal balance between stability and excitability. There are many drugs that anesthesiologists can use to induce unconsciousness in patients. Exactly how these drugs cause the brain to lose consciousness has been a longstanding question, but MIT neuroscientists have now answered that question for one commonly used anesthesia drug.

Biomarkers reveal how patients with glaucoma may respond to treatment
Markers in the blood that predict whether glaucoma patients are at higher risk of continued loss of vision following conventional treatment have been identified by researchers at UCL and Moorfields Eye Hospital. Over 700,000 people in the UK have glaucoma and it is the leading cause of irreversible blindness worldwide.
