Cancer Research: DNA Repair Mechanism Further Elucidated
Cancer Research: DNA Repair Mechanism Further Elucidated
Researchers at the University of Würzburg, led by Caroline Kisker in cooperation with Claudia Höbartner, discovered how the protein XPD detects a severe DNA damage and controls its repair. The XPD protein is a central component of our body's own 'DNA repair team', known as nucleotide excision repair (NER).

Food swaps could cut greenhouse gas emissions from groceries by a quarter
Food swaps could cut greenhouse gas emissions from groceries by a quarter
A new study in Australia has shown that shoppers making simple food and drink switches could reduce greenhouse gas emissions from groceries by 26%. Researchers from The George Institute for Global Health and Imperial College London's School of Public Health conducted the most detailed analysis ever on the environmental impacts of a country's food buying behaviour.

Retail banks: cryptocurrencies on the rise as an investment
Retail banks: cryptocurrencies on the rise as an investment
Despite widespread skepticism, more and more retail banks are offering cryptocurrencies as a fully-fledged asset class. While some banks are specifically building up their own expertise in blockchain, most are relying on third-party providers. These are the findings of a new study by Lucerne University of Applied Sciences and Arts.

Stress in Childhood: differences between Neanderthals and modern humans in the Paleolithic Age
Stress in Childhood: differences between Neanderthals and modern humans in the Paleolithic Age
Although the children of Neanderthals, who lived until around 40,000 years ago, and those of modern humans of the Upper Paleolithic Age 50,000 to 12,000 years ago were probably subjected to comparable stresses, systemic stress peaked at different stages of development. Research into their teeth has revealed that enamel growth reflects stress phases caused by issues such as disease and malnutrition during the early years of life.

Sanfilippo syndrome: Major advancement towards developing a treatment
For the first time, a team co-led by Alexey Pshezhetsky resolved the structure of the enzyme deficient in Sanfilippo disease, a rare pediatric neurodegenerative disorder. For the first time, a team co-led by CHU Sainte-Justine researcher and professor in the Faculty of Medicine at Université de Montréal, Alexey Pshezhetsky has succeeded in resolving the unique structure of the HGSNAT enzyme, a deficiency of which causes Sanfilippo syndrome, a rare pediatric disease affecting the central nervous system.

Cultural Networks of Central African Hunter-Gatherers Have Ancient Origin
Cultural Networks of Central African Hunter-Gatherers Have Ancient Origin
Extensive social networks between different hunter-gatherer groups in the Congo Basin existed long before agriculture arrived in the region. This continent-wide exchange preserved a cultural diversity that evolved thousands of years ago, as researchers from the University of Zurich show based on musical instruments, specialized vocabulary and genetic information.

Moving Components in Miniature
Moving Components in Miniature
Electromagnetic engines can't be reduced to just any size. It takes clever engineering tricks to generate active movement in miniature format. Researchers in Bochum are constantly coming up with new technologies. Over the years, a great many technical components have been shrunk in size. But miniaturization reaches its limits when tiny systems are supposed to move actively, because conventional electromagnetic motors become inefficient when reduced to miniature format.

Multi-purpose mucus
Multi-purpose mucus
What mucins can do in medicine They are in our eyes, on our tongues, and in our stomachs: Protective layers of mucus, a slime consisting primarily of mucins. These are molecules which bind water to form a natural lubricant. Researchers at the Technical University of Munich (TUM) use them to develop coatings for contact lenses and intubation tubes, healing plasters for use on the tongue and intestines, and much more.

Alzheimer’s disease risk: hyperactivation of memory circuits
By exploring the effects of sport on memory, scientists from the University of Geneva have discovered compensatory mechanisms in the brains of young individuals at genetic risk of developing Alzheimer's disease. The benefits of physical activity on health are widely accepted, and those on cognitive capacity are increasingly well known.

New therapy proven effective against rejection in kidney transplantation
New therapy proven effective against rejection in kidney transplantation
Antibody-mediated rejection (AMR) is one of the most common causes of kidney transplant failure. To date, however, no treatment has proven effective in combating this complication in the long term. As part of an international and multidisciplinary clinical study led by Georg Böhmig and Katharina Mayer, Clinical Division of Nephrology and Dialysis, Department of Medicine III at MedUni Vienna and University Hospital Vienna, a new therapeutic principle in transplant medicine has been found to be both safe and highly effective.

How and why different cell division strategies evolve
How and why different cell division strategies evolve
Scientists, in collaboration with researchers at EMBL Heidelberg, have discovered that a group of marine protists (eukaryotic organisms) closely related to animals use open or closed mitosis based on their life cycle stages, suggesting that the way animal cells perform cell division evolved long before animals themselves.

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data
This computer-generated 3D model of Venus' surface shows the volcano Sif Mons, which is exhibiting signs of ongoing activity. Using data from NASA's Magellan mission, Italian researchers detected evidence of an eruption while the spacecraft orbited th. Credit: NASA/JPL" An analysis of data from Magellan's radar finds two volcanoes erupted in the early 1990s.

Imperceptible sensors made from ’electronic spider silk’ can be printed directly on human skin
Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal. The method, developed by researchers from the University of Cambridge, takes its inspiration from spider silk, which can conform and stick to a range of surfaces.

Nicotine use rises among young adults in England but cigarette smoking continues to decline
Nicotine use rises among young adults in England but cigarette smoking continues to decline
Overall nicotine use has risen among adults in England since disposable vapes started becoming popular, due to a rapid increase in vaping among young adults coupled with a modest overall decline in smoking, finds a new study by UCL researchers. Importantly, the declines in smoking were most pronounced in age groups with the largest increases in vaping.

Ambitious targets are needed to end ocean plastic pollution by 2100
Research suggests that plastic pollution must be reduced by at least 5% every year to make progress towards UN targets by the end of the century. The study, a collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics - plastics less than 5 mm in length - in the surface oceans.
