Trust is good - control is better
Although strict limits exist, batteries can still contain too many harmful ingredients such as mercury, cadmium and lead. The Federal Office for the Environment (FOEN) has therefore launched a control campaign. Empa has laid the foundations for this with a specially developed method for analyzing heavy metals .

Listening to the Radio on the Far Side of the Moon
Key Takeaways Researchers can use the radio-quiet far side of the moon to listen for a never-before-heard signal from the "Dark Ages" of the universe. The LuSEE-Night experiment will act as a pathfinder for future experiments, testing equipment and techniques in the harsh lunar environment. The Berkeley Lab team is now building the experiment's antenna, which will head to the moon and hunt for radio waves.

A close-up of biological nanomachines
Something that is particularly important for the system is the role played by peroxisomes in fat metabolism. This is because they not only dismantle the fats, they also convert them into usable energy which itself is indispensable for a variety of processes in the body. Without peroxisomes, dangerous quantities of certain fats can accumulate, which would give rise to serious health problems.

Depression, anxiety may be among early signs of MS
Science, Health & Technology Brett Goldhawk New research from the University of British Columbia is painting a clearer picture of the early signs of multiple sclerosis (MS), showing that people are nearly twice as likely to experience mental illness in the years leading up to the onset of the diseases.

Fainting from needles may be alleviated by reducing pain - study
Feeling faint after your booster shot? A team of SFU researchers found that needle pain may increase the conditions that lead some people to faint. In a recent paper published in the journal Clinical Autonomic Research , the researchers suggest those with a fear of needles or history of fainting could benefit from topical anesthetics to help reduce the pain.

Can a simple eye exam help diagnose autism?
Researchers studied a cohort of 400 children aged 9 to 10 in New Zealand who exhibited a full range of possible autism traits and conducted a variety of vision and visuomotor processing tests with them. Females are often underdiagnosed with being on the autism spectrum because they often mask their symptoms more successfully than males.

How to manage exam season: take breaks and breathe
Associate Professor Paul Ginns' research shows that rest and relaxation maximises academic performance, even during exams. He explains why in The Conversation. Around Australia, Year 12 students are heading into the final stretch of study before exams start in early term 4. This is typically seen as a very intense period of preparation.

Ethnicity and early menopause increase risk of type 2 diabetes
University of Queensland research has found ethnicity plays a significant role in determining a woman's risk of developing type 2 diabetes after early menopause. Dr Hsin-Fang Chung and a team of researchers from the UQ School of Public Health analysed the health data of more than 330,000 postmenopausal women from 13 studies conducted in Australia, United Kingdom, Netherlands, Sweden, Japan, and China.

How to save plants from climate change? Just ask them
Science + Technology UCLA biologists can infer trees' desired conditions from their wood and leaves Key takeaways Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species.

Climate change intensifies extreme heat in the soil
Climate change intensifies extreme heat in the soil
For a long time, little attention was paid to ground temperatures because, in contrast to air temperatures near the surface, hardly any reliable data were available due to the significantly more complex measurement.

Methane and carbon dioxide found in atmosphere of habitable zone exoplanet
Methane and carbon dioxide found in atmosphere of habitable zone exoplanet
Astronomers have for the first time discovered carbon-based molecules in the atmosphere of an exoplanet in the habitable zone. The international team, which includes Cardiff University astrophysicist Dr Subi Sarkar, used data from the James Webb Space Telescope (JWST) to detect methane and carbon dioxide in the atmosphere of K2-18 b. Orbiting a red-dwarf star 124 light years away in the constellation of Leo, K2-18 b is a 'sub-Neptune' exoplanet 2.6 times the size of Earth and 8.6 times the mass of Earth.

Nanopore sequencing and DNA barcoding method gives hope of personalised medicine
Nanopore sequencing and DNA barcoding method gives hope of personalised medicine
With the ability to map dozens of biomarkers at once, a new method could transform testing for conditions including heart disease and cancer. Currently, many diseases are diagnosed from blood tests that look for one biomarker (such as a protein or other small molecule) or, at most, a couple of biomarkers of the same type.

A promising method for the degradation of nanoplastics in water
A promising method for the degradation of nanoplastics in water
Researchers at the Autonomous University of Madrid (UAM) have developed a process based on the photo-Fenton method that allows the efficient degradation of polystyrene nanoplastics in water. This breakthrough could be key in the fight against plastic pollution, especially in wastewater treatment plants (WWTP).

New vaccine technology could protect from future viruses and variants
Studies of a 'future-proof' vaccine candidate have shown that just one antigen can be modified to provide a broadly protective immune response in animals. The studies suggest that a single vaccine with combinations of these antigens - a substance that causes the immune system to produce antibodies against it - could protect against an even greater range of current and future coronaviruses.

Widely-used COVID-19 antiviral could be helping SARS-CoV-2 to evolve
Widely-used COVID-19 antiviral could be helping SARS-CoV-2 to evolve
Molnupiravir, an antiviral drug used to treat patients with COVID-19, appears to be driving SARS-CoV-2 to mutate and evolve, with some of these new viruses being transmitted onwards, a new study has shown. It is not clear, however, whether these mutated viruses pose an increased risk to patients or are able to evade the vaccine.

Brain imaging tool falls short for human tissue
A common research tool used to measure brain inflammation and test new dementia drugs may not be as helpful as scientists had hoped. In clinical research, scientists use a type of imaging called positron emission tomography (PET) to gain a detailed view of what's happening in the brain. One of the markers targeted by scans, called translocator protein (TSPO), has long been used to measure inflammation driven by microglia - the specialised immune cells in the brain which respond to damage and disease.

Marker for brain inflammation finally decoded
Marker for brain inflammation finally decoded
An international team co-led by UNIGE and HUG has decoded the only protein that can be used to ''see'' neuroinflammation. This discovery will improve the understanding of neurological and psychiatric disease mechanisms. Inflammation is the sign that our body is defending itself against an aggression.

Crystallization as the Driving Force
Crystallization as the Driving Force
Scientists from the Friedrich Schiller University of Jena and the Friedrich Alexander University of Erlangen-Nuremberg have successfully developed nanomaterials using a so-called bottom-up approach. As reported in the scientific journal ACS Nano, they exploit the fact that crystals often grow in a specific direction during crystallisation.

How can the use of plastics in agriculture become more sustainable?
How can the use of plastics in agriculture become more sustainable?
It is impossible to imagine modern agriculture without plastics. 12 million tonnes are used every year. But what about the consequences for the environment? An international team of authors led by Thilo Hofmann from the Division of Environmental Geosciences at the University of Vienna addresses this question in a recent study in Nature Communication Earth and Environment .

The unintended consequences of development cooperation
Development cooperation often results in unintended effects, besides the intended ones. For instance, providing financial support to women can unintentionally lead to increased domestic violence if their husbands feel disadvantaged. Evaluation reports must also pay attention to these sorts of "side effects", argues researcher Dirk-Jan Koch.
