A new study sheds light on how the specter of dementia and chronic pain reduce people's desire to live into older ages. Among Norwegians 60 years of age and older the desire to live into advanced ages was significantly reduced by hypothetical adverse life scenarios with the strongest effect caused by dementia and chronic pain. The paper is among the first to study Preferred Life Expectancy (PLE) based on hypothetical health and living conditions.

Ecologists at the University of Hong Kong have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-caught, a key piece of evidence required in many cases to determine whether a trade is legal or not. They have applied this technique to the yellow-crested cockatoo, a critically endangered species from Indonesia/Timor-Leste with a global population of fewer than 2,500, according to the International Union for the Conservation of Nature.

New study provides the first examination of the impact school meals programs have on the children of those served, finding the next generation of beneficiaries tend to have better growth outcomes.

The impact of El Nino on East Asian climate under a warmer climate will be dominated by the change in El Nino decaying pace.

In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression, thanks to Albert Sneppen, student at the Niels Bohr Institute. The result, which even is more useful in realistic black holes, has just been published in the journal Scientific Reports.

Whether birds can taste sweet was previously unclear. An international team of researchers has now shown that songbirds, a group containing over 4,000 species, can sense sweetness regardless of their primary diets. The study highlights a specific event in the songbird ancestors that allowed their umami (savoury) taste receptor to recognise sugar. This ability has been conserved in the songbird lineage, influencing the diet of nearly half of all birds living today.

Sussex mathematicians have created a new modelling toolkit which predicts the impact of COVID-19 at a local level with unprecedented accuracy.

Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research.The findings, revealed by a research team including University of Leeds academics, show that forests are being cut down at increasingly higher altitudes and on steeper slopes in order to make way for agricultural intensification.

Despite legislation to prevent the marketing of tobacco products to children, tobacco companies have shrewdly adapted their advertising tactics to circumvent the ban and maintain their access to this impressionable--and growing--market share.

Machine learning accelerates the search for promising Moon sites for energy and mineral resources.

Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions. This, according to a new study by researchers at the University of Copenhagen, among others.

Researchers have developed a sensor that can be implanted anywhere in the body, for example under the tip of a severed finger; the sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve.This unique development is biocompatible ("human-body friendly") and does not require electricity, wires, or batteries.

RUDN and Shahid Beheshti University (SBU) chemist proposed a protocol for converting cellulose into a catalyst for the synthesis of oxadiazoles. The new approach makes the catalyst 3 times more stable compared to the same catalyst obtained by the traditional method.

Photosynthesis is at the core of all life. But what lies at the crux of photosynthesis?Scientists have long known of the specific components of the cell where photosynthesisoccurs, but the precise mechanisms by which these components are maintained remainunknown. Now, the possibility of unprecedented high?resolution visualization using cryoelectronmicroscopy has allowed a team of scientists to reveal how the structural integrityof the site of one half of the photosynthesis process is maintained.

RUDN University mathematicians have developed a model for calculating the density of 5G stations needed to achieve the required network parameters.

A special issue highlights the Fengyun satellites' data applications and encourages further research among domestic and international collaborators

For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has visited the Sagami River to collect algal samples to understand how living things evolved different sexes. The threes sexes of the Pleodorina starrii algae are male, female, and a third sex called bisexual in reference to the fact that it can produce both male and female sex cells in a single genotype and exists due to normal expression of the species' genes.

Children living in urban areas with high levels of air pollution, noise and traffic may be at higher risk of childhood obesity, according to a study by the Barcelona Institute for Global Health (ISGlobal)--a centre supported by the "la Caixa" Foundation--and the University Institute for Primary Care Research Jordi Gol (IDIAP Jordi Gol). The study was funded by the La Marató de TV3 Foundation.

The UN Convention on Biological Diversity (CBD) Secretariat today released the first official draft of a new Global Biodiversity Framework to guide actions worldwide through 2030 to preserve and protect Nature and its essential services to people.

Scientists identified hepatocellular carcinoma (HCC) subtypes with distinctive metabolic phenotypes through bioinformatics and machine learning methods, and elucidated the potential mechanisms based on a metabolite-protein interaction network and multi-omics data.
