Active platinum species

Eurekalert - Jun 10 2021 - 00:06
Highly dispersed platinum catalysts provide new possibilities for industrial processes, such as the flameless combustion of methane, propane, or carbon monoxide, which has fewer emissions and is more resource efficient and consistent than conventional combustion. In the journal Angewandte Chemie, a team of researchers reports on which platinum species are active in high-temperature oxidations and what changes they can undergo in the course of the process--important prerequisites for the optimization of catalysts.

Memory biomarkers confirm aerobic exercise helps cognitive function in older adults

Eurekalert - Jun 10 2021 - 00:06
Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer's.

LIM domain only 1: One gene, many roles in cancer

Eurekalert - Jun 10 2021 - 00:06
The scientific world has been delving ever deeper into cancer, scourging for even the tiniest biomolecule that could amp up the cure for the deadly disease. A recent discovery in this regard is the gene LIM domain only 1, whose coded protein has a role in tumor formation. In a new article in Chinese Medical Journal, researchers have reviewed studies detailing molecular features of this gene for potential practical applications in cancer cure.

Noise and light pollution can change which birds visit our backyards

Eurekalert - Jun 10 2021 - 00:06
Using more than 3.4 million citizen scientist observations of 140 different bird species across the continental U.S., researchers found that common bird species avoided areas with excessive noise. In areas where light and noise pollution both occurred, many additional species avoided backyard feeders. Seasonal patterns and variation in the length of night also influenced how species respond to light pollution.

For bay oysters, protection plus restoration creates healthiest reefs

Eurekalert - Jun 10 2021 - 00:06
Actively restoring oyster reefs--beyond simply protecting them from harvest--can create big payoffs for habitat quality and the other species that flock to them. A new study from the Smithsonian Environmental Research Center, published June 3 in the journal Marine Ecology Progress Series, compared restored, protected and harvested areas using photos and video footage from roughly 200 sites.

LSU Health New Orleans study reports compound blocks SARS-CoV-2 and protects lung cells

Eurekalert - Jun 10 2021 - 00:06
Research conducted at LSU Health New Orleans Neuroscience Center of Excellence reports that Elovanoids, bioactive chemical messengers made from omega-3 very-long-chain polyunsaturated fatty acids discovered by the Bazan lab in 2017, may block the virus that causes COVID-19 from entering cells and protect the air cells (alveoli) of the lung.

Novel materials: Sound waves traveling backwards

Eurekalert - Jun 10 2021 - 00:06
Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. Rotons are an exception: their speed of sound changes significantly with the wavelength, it is also possible that the waves travel backwards. Researchers at Karlsruhe Institute of Technology are studying the possibilities of using rotons in artificial materials. These metamaterials might be used in the future to manipulate or direct sound in ways that have never been possible before.

Cells construct living composite polymers for biomedical applications

Eurekalert - Jun 10 2021 - 00:06
Biomedical engineers at Duke University have demonstrated that a class of interwoven composite materials called semi-interpenetrating polymer networks (sIPNs) can be produced by living cells. The approach could make these versatile materials more biologically compatible for biomedical applications such as time-delayed drug delivery systems.

Depression in old age: Smoking and other risk factors less decisive

Eurekalert - Jun 10 2021 - 00:06
Smoking, high blood pressure, diabetes, and other risk factors for cardiovascular diseases also increase the likelihood of suffering from depressive mood or depression. Until now, however, it was unclear whether this influence changes over the course of life or is independent of age. A study by the Max Planck Institute for Human Cognitive and Brain Sciences shows: Among those over 65, these risk factors play a smaller role in relation to depression than among younger.

Institutional environments trap disabled geoscientists between a rock and a workplace

Inaccessible workplaces, normative departmental cultures and 'ableist' academic systems have all contributed to the continued underrepresentation and exclusion of disabled researchers in the Geosciences, according to an article published today in Nature Geosciences.

Dinosaurs lived in greenhouse climate with hot summers

Eurekalert - Jun 10 2021 - 00:06
Paleoclimatologist Niels de Winter and colleagues developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter summers than previously thought. The results suggest that in the mid latitudes, seasonal temperatures will likely rise along with climate warming, while seasonal difference is maintained. This results in very high summer temperatures.

As a decade of ecosystem restoration kicks off, don't forget the people

Eurekalert - Jun 10 2021 - 00:06
Global ecosystem restoration efforts are often measured by billions of trees planted or square kilometers of land restored. But there is a critical void in the agenda: the social and political dimensions that make restoration a success.

The rocky road to accurate sea-level predictions

Eurekalert - Jun 10 2021 - 00:06
The type of material present under glaciers has a big impact on how fast they slide towards the ocean. Scientists face a challenging task to acquire data of this under-ice landscape. Choosing the wrong equations for the under-ice landscape can have the same effect on the predicted contribution to sea-level rise as a warming of several degrees, says Henning Åkesson, who led a new published study on Petermann Glacier in Greenland.

As more people are taking advantage of music on the go, personal audio systems are pumping up the volume to the detriment of the listener's hearing. During the 180th ASA Meeting, Daniel Fink from The Quiet Coalition and Jan Mayes will talk about current research into personal audio system usage and the need for public health hearing conservation policies. Their session, "Personal audio system use can harm auditory health," will take place Thursday, June 10.
