Hedges reduce pollution at breathing height in shallow street canyons, study confirms

Science Daily - 14/10/2021
An extensive field study into air quality along a road lined with buildings has confirmed that hedges can help mitigate traffic-related pollution up to 1.7m, reducing the pollutants breathed by pedestrians, young children and cyclists.

By 2500 Earth could be alien to humans

Science Daily - 14/10/2021
To fully grasp and plan for climate impacts under any scenario, researchers and policymakers must look well beyond the 2100 benchmark. Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.

The Southern Ocean’s role in driving global carbon cycle stronger than expected

Science Daily - 14/10/2021
Based on the most comprehensive winter study to date, conducted in the Southern Ocean during July and August 2017, scientists were able to show that phytoplankton were indeed active during the icy cold and dark winter months. These findings are important for predictive global climate models, which currently are based predominantly on spring and summer seasons. With the addition of data from winter, the models can now better represent the atmosphere-to-ocean carbon transfer cycle over seasons. For scientists, this is a step forward in analyzing the sensitivity of this transfer to climate change.

Evidence of superionic ice provides new insights into unusual magnetic fields of Uranus and Neptune

Science Daily - 14/10/2021
Not all ice is the same. The solid form of water comes in more than a dozen different - sometimes more, sometimes less crystalline - structures, depending on the conditions of pressure and temperature in the environment. Superionic ice is a special crystalline form, half solid, half liquid - and electrically conductive. Its existence has been predicted on the basis of various models and has already been observed on several occasions under - very extreme - laboratory conditions. New results provide another piece of the puzzle in the spectrum of the manifestations of water. And they may also help to explain the unusual magnetic fields of the planets Uranus and Neptune, which contain a lot of water.

Artificial intelligence helps to find new natural substances

Science Daily - 14/10/2021
More than a third of all medicines available today are based on active substances from nature and a research team has developed a procedure to identify small active substance molecules much more quickly and easily.

Scientists discover large rift in the Arctic’s last bastion of thick sea ice

Science Daily - 14/10/2021
In May 2020, a hole a little smaller than the state of Rhode Island opened up for two weeks in the Last Ice Area, a million-square-kilometer patch of sea ice north of Greenland and Ellesmere Island that's expected to be the last refuge of ice in a rapidly warming Arctic. The polynya is the first one that has been identified in this part of the Last Ice Area.

Climate change threatens hydropower energy security in the Amazon basin

Science Daily - 14/10/2021
Hydropower is the dominant source of energy in the Amazon region, the world's largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the Amazon's hydropower capacity.

Bridging optics and electronics

Science Daily - 14/10/2021
Researchers have developed a simple spatial light modulator made from gold electrodes covered by a thin film of electro-optical material that changes its optical properties in response to electric signals.

Possible alternative treatment for Lyme disease

Science Daily - 14/10/2021
Researchers have described a new antibiotic that appears to have the potential to cure Lyme disease.

Clues emerge: How harmless bacteria go rogue turning into deadly flesh-eating variants

Science Daily - 14/10/2021
A new study found that the environmental lifestyle that bacteria possess reveal why some go rogue and turn deadly while others remain harmless to humans. The findings focus on Vibrio vulnificus, better known as the flesh-eating bacteria. However, what the scientists found could help create a model that may well extend to other human pathogens.

New statistical study finds link between protein evolution and thermal variation

Science Daily - 14/10/2021
A recent statistical study has revealed some of the constraints and directions in the evolution of the structure and function of proteins. Better models of protein structural dynamics may allow researchers to understand more of this fundamental mystery in living organisms.

Ranking healthfulness of foods from first to worst

Science Daily - 14/10/2021
Food Compass, a new nutrient profiling system, rates the healthfulness of foods, beverages, and mixed meals on a score of 1-100 based on a wide range of science-based attributes. This adaptable tool aims to encourage healthier choices, spur industry reformulation, and guide nutrition policies.

Americans are eating more ultra-processed foods

Science Daily - 14/10/2021
Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study.

Scientists map brain circuit that drives activity in fertile females

Science Daily - 14/10/2021
Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.

Lone changer: Fish camouflage better without friends nearby

Science Daily - 14/10/2021
While gobies aren't the only fish with camouflage abilities, new research shows that their colour change is influenced by their social context: they transform faster and better when alone. This is likely an adaptive, stress response to perceived threat from predators - with possible application to other camouflaging species.

Cell-based influenza vaccine provides protection against the flu in children

Science Daily - 14/10/2021
A cell-based influenza vaccine has effectively provided protection against the flu in children and adolescents, according to a new study.

Data continues to show that American’s need at least 5 hours per week of physical activity to prevent some cancers

Science Daily - 14/10/2021
A new report finds more than 46,000 cancer cases annually in the United States could be prevented if Americans met the 5 hours per week of moderate-intensity recommended physical activity guidelines.

Bone-loss discovery points to new treatment for osteoporosis

Science Daily - 14/10/2021
A new discovery about osteoporosis suggests a potential treatment target for that brittle-bone disease and for bone loss from rheumatoid arthritis.

After two hours, sunscreens that include some zinc oxide can lose effectiveness, become toxic

Science Daily - 14/10/2021
Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to scientists.

Sustainable farming: There’s no one solution

Science Daily - 14/10/2021
Sustainable agriculture will not be achieved by one universal solution. A meta-analysis shows that the current focus on no-till farming does not achieve the desired results. A sustainable system of agriculture must be designed for local needs and in dialog with local farmers.
