'Brain state' behind social interaction uncovered
’Brain state’ behind social interaction uncovered
The brain's emotion-processing center — the amygdala — is one of several brain regions involved in social behavior. But the exact role that this almond-shaped structure plays in the so-called ‘social brain' remains mysterious. Now, the Lüthi group has found that the activity of different populations of neurons in the amygdala reflects whether mice interact with their peers, or whether they focus on self-centered behaviors such as grooming.

Tackling tumors with two types of virus
Tackling tumors with two types of virus
An international research group led by the University of Basel has developed a promising strategy for therapeutic cancer vaccines. Using two different viruses as vehicles, they administered specific tumor components in experiments on mice with cancer in order to stimulate their immune system to attack the tumor.

New, highly precise ’clock’ can measure biological age
Two scientists at the CECAD Cluster of Excellence in Aging Research have developed a method that can determine an organism's biological age with unprecedented precision / researchers expect new insights into how the environment, nutrition, and therapies influence the aging process Using the model organism Caenorhabditis elegans , researchers at the University of Cologne have developed an 'aging clock' that reads the biological age of an organism directly from its gene expression, the transcriptome.

Strongest evidence yet of ’migration gene’
A team from the Chinese Academy of Sciences and Cardiff University say they have found the strongest evidence yet of a “migration gene? in birds. The team identified a single gene associated with migration in peregrine falcons by tracking them via satellite technology and combining this with genome sequencing.

Cuttlefish can pass the ’snacking test,’ study finds
A popular  TikTok challenge  has evolved in which kids resist eating snacks; a new study finds that cuttlefish can do the same. According to the research, cuttlefish can delay gratification-wait for a better meal rather than be tempted by the one at hand-and those that can wait longest also do better in a learning test. This intriguing report marks the first time a link between self-control and intelligence has been found in an animal other than humans and chimpanzees.

Green tea supplements can modulate facial development in Down syndrome
Recerca A new study led by Belgian and Spanish researchers published in the journal Scientific Repor ts adds evidence about the potential benefits of green tea extracts in Down syndrome. The researchers observed that the intake of green tea extracts can reduce facial dysmorphology in children with Down syndrome when taken during the first three years of life.

The "Breathing" Himalaya
Great Mountains Grow in a Cycle of Rising and Falling How and when do mountains grow? It is tempting to think of mountain formation as something that takes place only extremely gradually, on timescales of tens of millions of years. One tectonic plate slowly pushes up against and slightly under another, until eventually up rises a mountain range.

Camera traps reveal newly discovered biodiversity relationship
Camera traps reveal newly discovered biodiversity relationship
Data scientists analyze photos from 15 tropical rainforests In one of the first studies of its kind, an analysis of camera-trap data from 15 wildlife preserves in tropical rainforests has revealed a previously unknown relationship between the biodiversity of mammals and the forests in which they live.

Through the looking glass: artificial ’molecules’ open door to ultrafast devices
Researchers from the University of Cambridge and Skoltech in Russia have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures that behave like molecules - and these 'artificial molecules' can potentially be engineered on demand.

Regular meat consumption linked with a wide range of common diseases
Regular meat consumption is associated with a range of diseases that researchers had not previously considered, according to a large, population-level study conducted by a team at the University of Oxford.  The results associate regular meat intake with a higher risk of various diseases, including heart disease, pneumonia and diabetes, but a lower risk of iron-deficiency anaemia.

Energy switching decisions could widen social inequalities
Energy switching decisions could widen social inequalities
New energy tariffs designed for a low carbon future could leave people on bad deals even worse off, research has found. The Leeds-led study found new types of contracts could benefit all types of customer, with opportunities to sell excess energy from solar panels or incentives for using energy at off-peak times.

Rice Plant Resists Arsenic
Rice Plant Resists Arsenic
The agricultural cultivation of the staple food of rice harbours the risk of possible contamination with arsenic that can reach the grains following uptake by the roots. In their investigation of over 4,000 variants of rice, a Chinese-German research team under the direction of Rüdiger Hell from the Centre for Organismal Studies (COS) of Heidelberg University and Fang-Jie Zhao of Nanjing Agricultural University (China) discovered a plant variant that resists the toxin.

Genetic study uncovers hidden pieces of eye disease puzzle 
Scientists have taken a significant step forward in their search for the origin of a progressive eye condition which can cause sight loss. A new study into keratoconus by an international team of researchers, including a Leeds group led by Chris Inglehearn, Professor of Molecular Ophthalmology in the School of Medicine , has for the first time detected DNA variations which could provide clues as to how the disease develops.

Lack of diversity in science
Lack of diversity in science
Women and the Global South are strikingly underrepresented Most publications in leading scientific journals are by male authors from English-speaking countries. This changes only slowly, according to a recent study on diversity in top authorship, concludes Bea Maas from the University of Vienna. Her new study examines the (non-existent) diversity in top authorship in science.

Parents depressed by pandemic had negative impact on kids’ education, well-being
Parent depression and stress early in the pandemic negatively contributed to young children's home education and anxiety, a University of Michigan study suggests. The stress could still be present today for some parents as their kids transition back to school while COVID-19 remains a danger. Continued support for children and parents will be needed, researchers said.

Ecology: The Scientific Literature Dominated by Men and a Handful of Countries
Publishing in peer-reviewed scientific journals is crucial for the development of a researcher's career. The scientists that publish the most often in the most prestigious journals generally acquire greater renown, as well as higher responsibilities. However, a team involving two CNRS researchers 1 has just shown that the vast majority of scientific articles in the fields of ecology and conservation biology are authored by men working in a few Western countries.

Follow the emotions to fight climate change
A researcher from the University of Geneva has compiled the scientific literature of the last five years linking emotion and climate change, highlighting the main levers that will make it possible to strengthen behaviour in favour of sustainable development. Emotions are often the victim of their bad reputation, as they are considered "irrational", but they play a major role in helping us assess the world and guide our behaviour.

Aging stars provide a new cosmological yardstick
Despite a century of measurements, astronomers can't agree on the rate at which the universe is expanding. A technique that relies on measuring distances to a specific type of aging star in other galaxies-called the J-region Asymptotic Giant Branch, or JAGB method-might be able to help. Astrophysicist and University of Chicago graduate student Abigail Lee is the lead author on a new paper that analyzed observations of light from a nearby galaxy to validate the JAGB method for measuring cosmological distances.
