Study highlights stark inequality in survival after cardiac surgery between paying and NHS patients
A new study has revealed paying patients are 20 per cent less likely to die or develop major complications, such as reintervention or stroke, after cardiac surgery than NHS patients - findings researchers say cannot be explained by socioeconomic factors alone. The study, led by academics at the University of Bristol, looked at the data of over 280,000 patients who underwent adult cardiac surgery over a ten-year period from 2009 to 2018 at 31 NHS cardiac units in England.

Plant diversity in Germany on the decline
Plant diversity in Germany on the decline
Most comprehensive evaluation of the occurrence of vascular plants in Germany to date Life Germany's plant diversity is on the decline: in the last 60 years, decreases by an average of 15 percent have been observed across Germany in over 70 percent of the more than 2,000 species examined. These are the findings of the most comprehensive analysis of plant data from Germany ever conducted, recently published in "Global Change Biology".

New research highlights impacts of weedkiller on wildlife
Prolonged exposure to environmentally relevant concentrations of the weedkiller Roundup causes significant harm to keystone species according to new research at the University of Birmingham. A team in the University's School of Biosciences used waterfleas, or Daphnia, to test the effects prolonged exposure to concentrations of Roundup deemed safe by regulatory agencies.

Digipredict digital twin will predict the evolution of Covid-19
Digipredict digital twin will predict the evolution of Covid-19
Under a cross-disciplinary program spearheaded by EPFL, scientists will develop an AI-based system that can predict whether Covid-19 patients will develop severe cardiovascular complications and, in the longer term, detect the likely onset of inflammatory disease. Covid-19 comes with a range of symptoms - from a sore throat and the loss of taste to more serious ones like lung failure.

A pair of lonely planet-like objects born like stars
A pair of lonely planet-like objects born like stars
An international research team led by the University of Bern has discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.

Big step with small whirls
Big step with small whirls
Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions - the future bits for "0" and "1" - can exist at room temperature, as they recently reported in the renowned .

Alzheimer’s Disease: Regulating Copper in the Brain Stops Memory Loss Among Mice
Alzheimer's disease is characterized by the presence of amyloid plaques 1 in the patient's brain. These plaques sequester copper, and contain approximately five times as much as a healthy brain. Two CNRS scientists from the Coordination Chemistry Laboratory recently developed, with their colleagues from the Guangdong University of Technology and Shenzhen University (China), a molecule that regulates the circulation of copper in the brain.

Variety: spice of life for bumble bees
Variety: spice of life for bumble bees
The yield and quality of many crops benefit from pollination, but it isn-t just honey bees that do this work: bumble bees also have a role. However, placing honey bee or bumble bee colonies next to the field does not guarantee that they will visit the desired plants since there may be other plant species flowering at the same time that prove more attractive.

Key type of immune cell ’self-renews’ in humans
A team of scientists has shown that a key type of immune cell "self-renews? in humans. It is an unexpected discovery, as it was previously thought this specific type of "senescent? killer immune cell had reached "end-stage? and would die following one more stint at helping people fight off - or live with - certain infections.

Scientists build whole functioning thymus from human cells
Researchers at UCL and the Francis Crick Institute have rebuilt a human thymus, an essential organ in the immune system, using human stem cells and a bioengineered scaffold. The study in mice marks an important step towards building artificial thymi for use in transplants. The thymus is an organ in the chest where T lymphocytes, which play a vital role in the immune system, mature.

New study links cadmium to more severe flu, pneumonia infections
High levels of cadmium, a chemical found in cigarettes and in contaminated vegetables, are associated with higher death rates in patients with influenza or pneumonia-and may increase the severity of COVID-19 and other respiratory viruses, according to a new study. "Our study suggests the public in general, both smokers and nonsmokers, could benefit from reduced exposure to cadmium,” said lead author Sung Kyun Park, associate professor of epidemiology and environmental health sciences at the University of Michigan School of Public Health.

Fishing alters fish behaviour and features in exploited ecosystems
The research study was carried out in two different habitats: in the Cíes Islands (Vigo), a protected marine area where recreational fishing is not allowed, and in contiguous areas open to fishing. Photo: Lluís Cardona. Recerca Not all specimens of the same species are the same: there is a marked variability within the same population and sometimes these morphological differences are translated into a different behaviour.

How the spread of the Internet is changing migration
The spread of the Internet is shaping migration in profound ways. A McGill-led study of over 150 countries links Internet penetration with migration intentions and behaviours, suggesting that digital connectivity plays a key role in migration decisions and actively supports the migration process. Countries with higher proportions of Internet users tend to have more people who are willing to emigrate.
