Grassland Ecosystems Become More Resilient with Age
Grassland Ecosystems Become More Resilient with Age
Reduced biodiversity affects the stability of the entire ecosystem. A long-term experiment now shows that grassland plant communities with multiple species need about 10 years to adjust to each other and produce an even amount of biomass again. Recent experiments have shown that the loss of species from a plant community can reduce ecosystem functions and services such as productivity, carbon storage and soil health.

When mental health moves through social media
When mental health moves through social media
Can a Tweet or a post on Instagram tell us something about our mental health? How meaningful is the relationship between well-being and the use of these platforms? To answer these questions, Marta Fadda, a researcher in bioethics at Universitą della Svizzera italiana, Oliver Grübner, a health geographer, and Marcus Wolf, a psychologist, at the University of Zurich conducted a series of studies to demonstrate the usefulness of social platforms for mental health research.

A new model for dark matter
Phase transition in early universe changes strength of interaction between dark and normal matter This NASA Hubble Space Telescope image shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689, containing about 1,000 galaxies and trillions of stars. Dark matter is an invisible form of matter that accounts for most of the universe's mass.

Covid-19 in pregnant women can damage the placenta and the foetus
Medicine & Science Using prenatal magnetic resonance imaging, a group of MedUni Vienna researchers examined the placentas and foetuses of women who tested positive for SARS-CoV-2 during pregnancy. Their research results demonstrate that the different strains of the virus that emerged during the pandemic led to varying degrees of damage: especially involving pre-Omicron variants, the detected placental lesions could potentially harm both development and health in some of the affected unborn children.

Optimising nitrogen removal from wastewater
Optimising nitrogen removal from wastewater
Too much nitrogen continues to enter many water bodies, negatively impacting ecosystems and human health. The anammox process co-developed by Eawag can make an important contribution to reducing outputs from wastewater treatment plants and also saves energy and resources. It has now been further optimised by researchers at Eawag.

Parental support linked to teen internet addiction
Parental support linked to teen internet addiction
Teenagers who feel well-supported by their parents are more likely to report increased internet addiction over time, in a surprise finding from a new University of Sydney Business School study. The researchers studied nearly 3,000 adolescents across four critical years of development, from Year 8 to Year 11 (age 14-17), to examine the link between social support and compulsive internet use.

New catalyst design could make better use of captured carbon, researchers say
A new catalyst design created by researchers at the University of Toronto's Faculty of Applied Science & Engineering could significantly improve the practicality of an electrochemical process that converts captured carbon dioxide into multi-carbon molecules - some of the key building blocks of the chemical industry.

Reproductive Life Factors and Hormone Therapy May Affect Women’s Risk of Parkinson’s Disease
The specific risk factors for the development of Parkinson's disease in women remain little studied and poorly known. Exposure to the hormones involved in female reproductive life is one of the avenues explored at the Epidemiology and Population Health Research Center (CESP) by a research team from Inserm, Université Paris-Saclay, Université de Versailles Saint-Quentin-en-Yvelines with Institut Gustave Roussy, which compared the reproductive characteristics of nearly 1,200 women with Parkinson's disease with those of other women from the E3N cohort .

A new model for dark matter
PRESS AND PUBLIC RELATIONS Phase transition in the early universe changes strength of interaction between dark and normal matter Dark matter remains one of the greatest mysteries of modern physics. It is clear that it must exist, because without dark matter, for example, the motion of galaxies cannot be explained.

James Webb Space Telescope identifies origins of icy building blocks of life
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discovered the deepest and coldest ice ever detected in such a molecular cloud.

Split-second of evolutionary cellular change could have led to mammals
A newly-published hypothesis, led by a UCL researcher, suggests a momentary leap in a single species on a single day millions of years ago might ultimately have led to the arrival of mammals - and therefore humans. Published in the Journal of Cell Science , Professor John Martin (UCL Division of Medicine) thinks a single genetic molecular event (inheritable epigenetic change) in an egg-laying animal may have resulted in the first formation of blood platelets, approximately 220 million years ago.

Scientists explain emotional 'blunting' caused by common antidepressants
Scientists explain emotional ’blunting’ caused by common antidepressants
Scientists have worked out why common anti-depressants cause around a half of users to feel emotionally -blunted-. In a study published today, they show that the drugs affect reinforcement learning, an important behavioural process that allows us to learn from our environment. According to the NHS, more than 8.3 million patients in England received an antidepressant drug in 2021/22.

NASA Measures Underground Water Flowing From Sierra to Central Valley
NASA Measures Underground Water Flowing From Sierra to Central Valley
This source accounts for about 10% of all the water that enters this highly productive farmland, including rivers and rain. In a recent study , scientists found that a previously unmeasured source - water percolating through soil and fractured rock below California's Sierra Nevada mountains - delivers an average of 4 million acre feet (5 cubic kilometers) of water to the state's Central Valley each year.

Risky business: Teenage chimps risk it all, like humans
Study (PDF): Distinct developmental trajectories for risky and impulsive decision-making in chimpanzees For young chimpanzees, gambling on the possibility of a big payout is an attractive prospect, whereas adult apes are more likely to hedge their bets, a new University of Michigan study shows. Research on primates can offer insights into the biology of human behavior.

Q&A: How AI can help people be more empathetic about mental health
Q&A: How AI can help people be more empathetic about mental health
Sarah McQuate Empathy is critical to having supportive conversations about mental health. But this skill can be tricky to learn, especially in the moment when a person is sharing something hard. A team led by researchers at the University of Washington studied how artificial intelligence could help people on the platform TalkLife , where people give each other mental health support.
