"Super-grafts" that could treat diabetes
By successfully strengthening pancreatic islets before transplantation, researchers at UNIGE and HUG are hoping for a significant improvement in the success of cell transplants in patients with severe diabetes. To save patients with a severe form of type 1 diabetes (characterized by the absence of functional insulin-producing cells), pancreatic cell transplantation is sometimes the last resort.

Science Barometer Switzerland: Trust in Science and Research Remains High
The Swiss population's trust in science and research is high to very high. As the Science Barometer Switzerland 2019 study shows, people in Switzerland have a positive attitude towards science and are keen to receive information about research, with climate and energy considered the most important topics.

On the way to intelligent microrobots
On the way to intelligent microrobots
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a micromachine that can perform different actions. First nanomagnets in the components of the microrobots are magnetically programmed and then the various movements are controlled by magnetic fields. Such machines, which are only a few tens of micrometres across, could be used, for example, in the human body to perform small operations.

In Hunting for Cures, Ethics Can Strengthen Clinical Trials
Clinical trials provide the cornerstone for evaluating the safety and efficacy of new drugs and therapies to treat disease. While trials are designed to follow established ethical and regulatory requirements, Alex John London , the Clara L. West Professor of Ethics and Philosophy at Carnegie Mellon University, said he believes there is room for improvement.

Wasps as an effective pest control for agriculture
Common wasp species could be valuable at sustainably managing crop pests, finds a new UCL-led experimental study in Brazil. The study, published in Proceedings of the Royal Society B , found that social wasps are effective predators that can manage pests on two high-value crops, maize and sugarcane.

It’s only funny.. if we say it
Jokes targeting certain groups of people are better received when the joke teller is part of the group being mocked, research from The University of Queensland has found. Dr Michael Thai from UQ's School of Psychology examined whether people's reactions to disparaging jokes changed based on who was telling the joke.

Mathematicians’ Work Helps Change How People Vote
Wes Pegden's expert testimony has changed the future of how states draw electoral districts As U.S. courts debate gerrymandering - the process of carving up electoral districts to disproportionately benefit one political party - Wes Pegden's work is helping to shape redistricting maps more fairly.

3,000-year-old Egyptian wheat genome sequenced for first time
3,000-year-old Egyptian wheat genome sequenced for first time
The genome of an ancient Egyptian wheat has been sequenced for the first time by a UCL-led team, revealing historical patterns of crop movement and domestication. The study was carried out by an international research team, which mapped the genetic code from a sample of wheat harvested over 3,000 years ago, that was excavated in 1924 from the Hememiah North Spur site in Egypt.

Q&A: A drug-free option for treating ADHD in children
Deciding how to treat attention deficit hyperactivity disorder in children can be a difficult decision for parents. Stimulants, such as Adderall and Ritalin, are the most commonly prescribed ADHD treatments — and are considered to be the most effective. But in April, the FDA approved the first device-based, non-drug therapy to treat ADHD in children.

Lawyers asked to advise on unethical issues
Nearly half (45%) of in-house lawyers have been asked to advise on an action with debatable ethics, according to research by UCL. The research, published in a new report ' Which way is the wind blowing? Understanding the moral compass of in-house legal counsel' also found that 39% of in-house lawyers had been asked to advise on something which was potentially illegal.

Deep sea vents had ideal conditions for origin of life
By creating protocells in hot, alkaline seawater, a UCL-led research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools. Previous experiments had failed to foster the formation of protocells - seen as a key stepping stone to the development of cell-based life - in such environments, but the new study, published iná Nature Ecology & Evolution , finds that heat and alkalinity might not just be acceptable, but necessary to get life started.

World-Leading Microscopes Take Candid Snapshots of Atoms in Their 'Neighborhoods'
World-Leading Microscopes Take Candid Snapshots of Atoms in Their ’Neighborhoods’
Taking the technology to low temperatures could enable advances in materials science and other fields By Jessica Scully Researchers use electron microscopy to produce high-resolution images at the atomic scale of everything from composite nanomaterials to single proteins. The technology provides invaluable information on the texture, chemistry, and structure of these materials.

4D-STEM Microscopes Take Candid Snapshots of Atomic ’Neighborhoods’
Scientists use powerful 4D-STEM electron microscopy technique to map out the best atomic 'hangouts' in high-performance materials W e can directly see the hidden world of atoms thanks to electron microscopes, first developed in the 1930s. Today, electron microscopes, which use beams of electrons to illuminate and magnify a sample, have become even more sophisticated, allowing scientists to take real-world snapshots of materials with a resolution of less than half the diameter of a hydrogen atom.

World-leading mental health research centre celebrates ’decade of discovery’
One of the world's leading centres for research into the underlying causes of mental health issues is marking its 10th anniversary. The MRC Centre for Neuropsychiatric Genetics and Genomics is also transitioning from a Medical Research Council Centre to a Cardiff University Centre, and Professor James Walters is taking over as director, replacing Professor Sir Michael Owen.

UW-Madison chemist searches for ways to bioengineer proteins within cells
Andrew Buller , professor of chemistry at the University of Wisconsin-Madison, wants to add more building blocks to the body's protein-making kit. In nature, there exist 20 of these building blocks, called amino acids, which make up the proteins that perform the work required to sustain life. Buller says scientists can create more, allowing them to expand the ways in which cells build proteins.

Dog ownership could reduce loneliness: study
Dog ownership could reduce loneliness: study
Sydney researchers find some evidence to suggest new dog owners experience a reduction in negative mood but further larger-scale trials are needed. A new University of Sydney trial lends weight to the expression 'man's best friend,' showing a sample of new dog owners saw a significant reduction in loneliness within three months of acquiring their pet.

Scientists develop adhesive which can be unstuck in a magnetic field, reducing landfill waste
Researchers at the University of Sussex have developed a glue which can unstick when placed in a magnetic field, meaning products otherwise destined for landfill, could now be dismantled and recycled at the end of their life. Currently, items like mobile phones, microwaves and car dashboards are assembled using adhesives.

Satellite tracking shows how ships affect clouds and climate
Satellite tracking shows how ships affect clouds and climate
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected. When ships burn fossil fuels, they release airborne particles containing various naturally occurring chemicals, including sulphur. These particles are known to modify certain types of clouds, which can affect climate.

Jaw-some wombats may be great survivors
Flexible jaws may help wombats better survive in a changing world by adapting to climate change's effect on vegetation and new diets in conservation sanctuaries. An international study, co-led by The University of Queensland's Dr Vera Weisbecker , has revealed that wombat jaws appear to change in relation to their diets.

Aquatic invasive species are short-circuiting benefits from mercury reduction in the Great Lakes
Using a combination of mercury, nitrogen and carbon isotope analysis - which he terms "fingerprinting" - on samples of lake trout archived from 1978 to 2012, researcher Ryan Lepak discovered there wasn't an obvious decrease in concentrations of mercury in these fish even though the sediment record revealed reduced mercury loading.
