Why older people should chill when it's hot out

Cooling off during extreme heat appears to help preserve cellular defenses

Why older people should chill when it's hot out
2021-04-27
(Press-News.org) Taking a break from extreme heat, by visiting a cooling center for example, could help our cells protect themselves from damage, according to preliminary findings from a new study. The research, which focused on older people, suggests temporarily cooling down on a hot day helps cells maintain autophagy, a process cells use to rid themselves of dangerous protein buildups caused by stressors like extreme heat.

"By lessening the time spent in a state of elevated internal body temperature, cooling centers may help to preserve autophagy in older adults, which may translate to greater cellular protection and improved health outcomes during an extreme heat event," said James J. McCormick, PhD, a postdoctoral fellow at the Human and Environmental Physiology Research Unit of the University of Ottawa in Canada, and the study's first author.

McCormick will present the research at the END

Neural implant monitors multiple brain areas at once, provides new neuroscience insights

Neural implant monitors multiple brain areas at once, provides new neuroscience insights
2021-04-27
How do different parts of the brain communicate with each other during learning and memory formation? A new study by researchers at the University of California San Diego takes a first step at answering this fundamental neuroscience question. The study was made possible by developing a neural implant that monitors the activity of different parts of the brain at the same time, from the surface to deep structures--a first in the field. Using this new technology, the researchers show that diverse patterns of two-way communication occur between two brain regions known to play a role in learning and ...

Rain, rain, go away: New waterproofing solution discovered by SFU chemistry team

2021-04-27
A new coating solution discovered by researchers at Simon Fraser University can transform regular materials into waterproof surfaces. The product will be cheaper to produce, free of harmful fluorinated compounds, and effective on a variety of materials. Their research findings have been published in Nature Communications. SFU chemistry professor and project lead Hogan Yu estimates that their patented waterproofing solution will be up to 90 percent cheaper to produce. Yu and his team are currently floating the idea by investors and companies with the goal of commercializing the product. The new formula was invented at Yu's lab when SFU graduate student Lishen Zhang and another student were working on an experiment in 2016. ...

After Brexit: Somewhat changed cooperation in the Council of the European Union

2021-04-27
In the Council of the European Union, member states mostly cooperate with other countries in their geographical proximity. However, once it became clear that the United Kingdom was going to leave the EU, the member states also started cooperating to a greater extent with ideologically like-minded members. Research from the University of Gothenburg shows that Brexit may, in part, have changed the logic behind how cooperation in the Council of the European Union is structured. The Council of the European Union is one of the most important EU decision-makers. Government ministers from the 27 EU member states participate in the ...

Study of oak forests of European Russia elucidates climate change in the region

Study of oak forests of European Russia elucidates climate change in the region
2021-04-27
Scientific classifications of forest vegetation on the territory of the former USSR, including the Republic of Tatarstan, previously used the dominant approach, traditional for northern countries, taking into account the dominance degree of one or another species in the main tree layer, or similarity in the composition of subordinate layers with the identification of cycles and series of associations. Currently, the classification of plant communities of the Republic of Tatarstan is made on a dominant-determinant basis and is reflected, for example, in the vegetation map of the Atlas of the Republic of Tatarstan and other publications. The classification ...

Plasma acceleration: Its all in the mix
2021-04-27
The LUX team at DESY is celebrating not just one but two milestones in the development of innovative plasma accelerators. The scientists from the University of Hamburg and DESY used their accelerator to test a technique that allows the energy distribution of the electron beams produced to be kept particularly narrow. They also used artificial intelligence to allow the accelerator to optimise its own operation. The scientists are reporting their experiments in two papers published shortly after one another in the journal Physical Review Letters. "It's ...

Cholestenone shows antibiotic properties against H. pylori

Cholestenone shows antibiotic properties against H. pylori
2021-04-27
Helicobacter pylori (H. pylori), a gram-negative pathogen that has infected half of the world's population is a Group I carcinogen according to the WHO. H. pylori resides in the gastric mucosa causing gastritis, ulcers, gastric cancers and malignant lymphoma of the stomach. It can be eradicated in most infected people using a combination of three drugs; antibiotics clarithromycin, amoxicillin, and gastric acid suppressants. Amoxicillin exerts antibacterial activity by inhibiting the biosynthesis of peptidoglycan present in the cell wall of bacteria, and clarithromycin exerts antibacterial activity by inhibiting protein synthesis. The current success rate of H. pylori eradication is about 90%. ...

Value from sewage? New technology makes pig farming more environmentally friendly

Value from sewage? New technology makes pig farming more environmentally friendly
2021-04-27
Anyone who lives in Okinawa, a subtropical island in Japan, has an appreciation of the intensity of its pig farming industry. The farms have a large effect on the island's economy and culture. According to Japan's Cabinet Office, as of 2018, there were over 225,000 pigs in Okinawa. Pork is a staple in the local diet and is found in many dishes in traditional restaurants. But the presence of the pig farms has another, less welcome, impact - the odor-y kind. Drive through some particularly farm-filled areas with the car's windows wound down and you're sure to be filled with regret. This smell is, at least in part, caused by a byproduct of the pig farming. ...

Future drones likely to resemble 300-million-year-old flying machine

2021-04-27
University of South Australia researchers have drawn inspiration from a 300-million-year-old superior flying machine - the dragonfly - to show why future flapping wing drones will probably resemble the insect in shape, wings and gearing. A team of PhD students led by UniSA Professor of Sensor Systems, Javaan Chahl, spent part of the 2020 COVID-19 lockdown designing and testing key parts of a dragonfly-inspired drone that might match the insect's extraordinary skills in hovering, cruising and aerobatics. The UniSA students worked remotely on the project, solving mathematical formulas at home on whiteboards, digitising stereo photographs of insect wings into 3D models, and using spare rooms as rapid prototyping workshops to test parts of the flapping wing drone. Their findings have ...

Loss of fauna in tropical forests impedes achieving Sustainable Development Goals

Loss of fauna in tropical forests impedes achieving Sustainable Development Goals
2021-04-27
The current loss of biological diversity is unprecedented and species extinctions exceed the estimated background rate many times over. Coinciding with increasing human domination and alteration of the natural world, this loss in abundance and diversity is especially pronounced with - but not limited to - fauna in the tropics. A new publication from scientists at the Lund University Centre for Sustainability Studies (LUCSUS) in Sweden and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Germany now explores the links between defaunation of tropical forests and the United ...

The bluest of blue: A new algae-based switch is lighting up biological research!

The bluest of blue: A new algae-based switch is lighting up biological research!
2021-04-27
Several organisms possess "ion channels" (gateways that selectively allow charged particles called ions to enter the cells and are integral for cell function) called "channelrhodopsins," that can be switched on and off with the help of light. Different channelrhodopsins respond to different wavelengths in the light spectrum. These channels can be expressed in foreign organisms (animals even in human) by means of genetic engineering, which in turn finds applications in optogenetics, or the application of light to modulate cellular and gene functions. So far, the shortest wavelength that a channelrhodopsin ...
