Natural ways of cooling cities
Natural ways of cooling cities
ETH scientists have been researching the effect of precipitation and population size on rising temperatures in cities compared with the surrounding countryside. They have found that more green spaces can help to lower temperatures in urban zones - but not everywhere. Urban heat islands are a phenomenon where the temperature in a city is noticeably higher than in the surrounding rural area.

UChicago’s history of dialogues with U.S. Supreme Court justices
Much of the research on the underlying causes of Alzheimer's disease focuses on amyloid beta (Aß), a protein that accumulates in the brain as the disease progresses. Excess Aß proteins form clumps or "plaques" that disrupt communication between brain cells and trigger inflammation, eventually leading to widespread loss of neurons and brain tissue.

Protein tangles linked with dementia seen for first time in patients’ brains
Scientists have visualised for the first time protein 'tangles' associated with dementia in the brains of patients who have suffered a single head injury. This is the finding of a new study led by scientists from Imperial College London, published Translational Medicine. In the early-stage study, researchers studied 21 patients who had suffered a moderate to severe head injury at least 18 years earlier (mostly from traffic accidents), as well as 11 healthy individuals who had not experienced a head injury.

Genetic factors influencing adult obesity take effect in early childhood
Genetic factors influencing adult obesity take effect in early childhood
Body mass index (BMI) in infants, children and adults is influenced by different genetic factors that change as we age, according to a major new study An international consortium of researchers, led by scientists at Imperial College London, the University of Surrey, and the University of Oulu, Finland, discovered that BMI in babies is influenced by a distinct set of genetic variants that play little role in determining weight in later life.

Tracks sulfur-based metabolism in the open ocean
One of the planet's most active ecosystems is one most people rarely encounter and scientists are only starting to explore. The open ocean contains tiny organisms - phytoplankton - that perform half the photosynthesis on Earth, helping generate oxygen for animals on land. A study by University of Washington oceanographers a plentiful marine nutrient.

When physicians integrate with hospitals, costs go up, Rice study says
When physicians integrate with hospitals, the cost of health care rises even though there's no evidence patients get better treatment, according to a new paper by experts at Rice University and Blue Cross and Blue Shield of Texas (BCBSTX). As hospitals gain more control over physicians, they may incentivize delivery of more services but not necessarily higher quality care, the researchers said in the paper, which appears in the Journal of General Internal Medicine.

Creation of new brain cells plays underappreciated role in Alzheimer’s
Much of the research on the underlying causes of Alzheimer's disease focuses on amyloid beta (Aß), a protein that accumulates in the brain as the disease progresses. Excess Aß proteins form clumps or "plaques" that disrupt communication between brain cells and trigger inflammation, eventually leading to widespread loss of neurons and brain tissue.

Putting a price on carbon pollution alone unlikely to help reach climate goals
Researchers show that carbon taxes alone cannot reduce emissions enough to reach the Paris Agreement targets. The Paris Agreement, signed in 2015, requires nations to collectively limit global warming to 2°C by 2100, and to pursue efforts to limit the temperature increase even further to 1.5°C.

Explosion in Plastic Pollution Post-World War II Seen in Marine Sediments
The amount of plastic fragments in Santa Barbara Basin sediments has been increasing exponentially since the end of World War II, according to a study by researchers from Scripps Institution of Oceanography at the University of California San Diego. The sharp increase matches a rise in the rate of plastic production worldwide and a surge in California's coastal population during the same time period.

Searching for the Origin of Life across the Universe
Searching for the Origin of Life across the Universe
Researchers from European countries discuss life in the Universe at the University of Vienna Astrobiology is a young, rapidly developing branch of science that seeks to address the question of whether life exists, or has existed, elsewhere in the Universe. It is by nature an interdisciplinary science that explores the origins of life, the conditions, and processes that support or challenge life, the influence of different environmental conditions on preservation and detection of biosignatures of past and present life.

Climate change impacts Wisconsin’s inland lakes
By Jennifer A. Smith Wisconsin's abundant inland lakes form a significant part of our state's identity, economy and how residents and visitors alike relax and have fun. However, like the Great Lakes that border Wisconsin, inland lakes-of which Wisconsin has more than 15,000-face threats due to climate change.

New insulation technique paves the way for more powerful and smaller chips
Researchers at KU Leuven and imec have successfully developed a new technique to insulate microchips. The technique uses metal-organic frameworks, a new type of materials consisting of structured nanopores. In the long term, this method can be used for the development of even smaller and more powerful chips that consume less energy.

How California Wildfires Can Impact Water Availability
How California Wildfires Can Impact Water Availability
New Berkeley Lab study uses supercomputers to analyze hydrological changes in a California watershed following a wildfire. In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires.

Fewer women do bowel screening test
Women are risking their lives by not taking part in bowel screening tests according to new research. A research team led by Professor Colin McCowan at the University of St Andrews and Dr Katie Robb from the University of Glasgow found that while 81% of women took part in cervical cancer screening and 73% in breast cancer screening only 60% of women took part in bowel screening.

Climate increasingly a mainstream health issue
Sydney has led a new Lancet comment on global warming and health; its publication came ahead of the latest declaration on climate as a health emergency, this time by the Australian Medical Association. Our experts explain why. The growing impact of climate on human health has prompted the Australian Medical Association to highlight climate change as a human health "emergency", it was  reported this week.

Researchers to investigate solitude and the physics of the Universe
Research investigating the effects of being alone on well-being is one of two Cardiff University projects to benefit from ¤3.38m funding from the European Research Council (ERC). Dr Netta Weinstein, from the School of Psychology, will receive ¤1.48m to investigate how people respond to solitude, at a time when more people are living alone.

Cracking "virus code" could help fight cancer
Virus experts from Cardiff University's School of Medicine have uncovered, for the first time, how a virus known as Adenovirus type 26 (Ad26), which has been used effectively in a tamed form as a vaccine, can infect human cells. Ad26 is a virus of great interest to the scientific and medical community.
