System linked to operational hospitals, shorter lockdowns, lives saved
2021-06-18
A staged alert system, designed by scientists and public health officials to guide local policies, helped one city prevent hospital surges and long lockdowns, according to new research published in the journal Nature Communications.
In a new study led by The University of Texas at Austin COVID-19 Modeling Consortium in collaboration with Northwestern University, researchers describe the system that has guided COVID-19 policies in Austin, Texas, for more than a year, helping to safeguard the health care system and avoid costly measures. It tracks the number of new daily COVID-19 hospital admissions and triggers changes in guidance when admissions cross specific threshold values. While using this staged alert system, the Austin metropolitan area has sustained the ...
Bio-inspired hydrogel protects the heart from post-op adhesions
2021-06-18
A hydrogel that forms a barrier to keep heart tissue from adhering to surrounding tissue after surgery was developed and successfully tested in rodents by a team of University of California San Diego researchers. The team of engineers, scientists and physicians also conducted a pilot study on porcine hearts, with promising results.
They describe their work in the June 18, 2021 issue of Nature Communications.
In rats, the hydrogel prevented the formation of adhesions altogether. In a small pilot study, porcine hearts treated with the hydrogel experienced less severe adhesions that were easier to remove. In addition, the hydrogel did not appear to cause chronic inflammation.
Adhesions--organ tissue sticking to surrounding tissue--are a relatively ...

Depression in dads of preemies deserves more attention
2021-06-18
While postpartum depression in new mothers is well recognized and known to increase if the newborn requires intensive care, depression in new fathers has not received much attention. A large study, published in the journal Pediatrics, found that both parents with a baby in the NICU are at risk, with depression symptoms identified in 33 percent of mothers and 17 percent of fathers. Strikingly, the probability of reporting depression symptoms declined significantly for mothers but not for fathers after the baby came home.
"Our findings point to the need for increased attention to the mental health of new fathers, during their baby's NICU stay and after discharge," said lead author Craig F. ...
Meringue-like material could make aircraft as quiet as a hairdryer
2021-06-18
An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath.
The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured. It could be used as insulation within aircraft engines to reduce noise by up to 16 decibels - reducing the 105-decibel roar of a jet engine taking off to a sound closer to that of a hair-dryer.
The aerogel's meringue-like structure makes it extremely light, meaning it could act as an insulator within aircraft engine nacelles, with almost no increase ...

"We were now looking to fit the technologies developed here in Innsbruck into the smallest possible space while meeting standards commonly used in industry." The new device aims to show that quantum computers will soon be ready for use in data centers. "We were able to show that ...
Long-term Himalayan glacier study
2021-06-18
The glaciers of Nanga Parbat - one of the highest mountains in the world - have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study conducted by researchers from the South Asia Institute of Heidelberg University. The geographers combined historical photographs, surveys, and topographical maps with current data, which allowed them to show glacial changes for this massif in the north-western Himalaya as far back as the mid-1800s.
Detailed long-term glacier studies that extend the observation period to the time before the ubiquitous ...
Sacred natural sites protect biodiversity in Iran
2021-06-18
How much do traditional practices contribute to the protection of local biodiversity? Why and how are sacred groves locally valued and protected, and how can this be promoted and harnessed for environmental protection? Working together with the University of Kurdistan, researchers of the University of Göttingen and the University of Kassel have examined the backgrounds of this form of local environmental protection in Baneh County, Iran.
"Around the world, local communities are voluntarily protecting certain parts of their surroundings due to religious ...
New study finds SARS-CoV-2 can infect testes
2021-06-18
Researchers at the University of Texas Medical Branch have observed that SARS-CoV-2, the virus that causes COVID-19, can infect the testes of infected hamsters. The findings, published in the journal Microorganisms, could help explain symptoms some men with COVID-19 have reported and have important implications for men's health.
As the pandemic goes on, clinicians continue to report their findings that COVID-19 affects more than just the lungs. Some patients have reported testicular pain and some reports have shown decreases in testosterone, a key hormone produced in the ...

Anti-science, partisan tweets could flag an outbreak
2021-06-18
In the realm of social media, anti-science views about COVID-19 align so closely with political ideology -- especially among conservatives -- that its predictability offers a strategy to help protect public health, a new USC study shows.
Resistance to science, including the efficacy of masks and vaccines, poses a challenge to conquering the coronavirus crisis. The goal of achieving herd immunity won't happen until society achieves consensus about science-based solutions.
The USC study's machine-learning assisted analysis of social media communications offers policymakers and public health officials new tools to anticipate shifts in attitudes ...

Altered microstructure improves organic-based, solid state lithium EV battery
2021-06-18
Only 2% of vehicles are electrified to date, but that is projected to reach 30% in 2030. A key toward improving the commercialization of electric vehicles (EVs) is to heighten their gravimetric energy density - measured in watt hours per kilogram - using safer, easily recyclable materials that are abundant. Lithium-metal in anodes are considered the "holy grail" for improving energy density in EV batteries compared to incumbent options like graphite at 240 Wh/kg in the race to reach more competitive energy density at 500 Wh/kg.

New analysis discusses role of managed retreat as a climate change response
2021-06-18
MIAMI--In a new analysis on managed retreat--the climate adaptation response of moving people and property out of harm's way--researchers explore what it would take for managed retreat to be supportive of people and their priorities. A key starting point is considering retreat alongside other responses like coastal armoring and not just as an option of last resort.
In a new paper in the journal Science, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researcher Katharine Mach argues that managed retreat should be viewed as a proactive option that can support communities and livelihoods in the face of climate change.

Tailored laser fields reveal properties of transparent crystals
2021-06-18
The surface of a material often has properties that are very different from the properties within the material. For example, a non-conducting crystal, which actually exhibits no magnetism, can show magnetisation restricted to its surface because of the way the atoms are arranged there. These distinct properties at interfaces and surfaces of materials often play a key role in the development of new functional components such as optoelectronic chips or sensors and are therefore subject to extensive research. An international research team from the University of Göttingen, the Max Planck Institute for Biophysical Chemistry Göttingen and the National Research Council Canada has now succeeded in investigating the surfaces of transparent crystals using ...
For the first time, researchers visualize metabolic process at the single-cell level
2021-06-18
Understanding cellular metabolism - how a cell uses energy- could be key to treating a wide array of diseases, including vascular diseases and cancer.
While many techniques can measure these processes among tens of thousands of cells, researchers have been unable to measure them at the single-cell level.
Researchers at the University of Chicago's Pritzker School of Molecular Engineering and Biological Sciences Division have developed a combined imaging and machine learning technique that can, for the first time, measure a metabolic process at both the cellular and sub-cellular levels.
Using a genetically encoded biosensor paired with artificial intelligence, ...
Tug-of-war receptors for sour taste in fruit flies sheds light on human taste biology
2021-06-18
PHILADELPHIA - Sour taste does not have the nearly universal appeal that sweet taste does. Slightly sour foods or drinks such as yogurt and lemon juice are yummy to many, but such highly sour foods as spoiled milk are yucky, even dangerous. Like humans, many other animals, including insects, prefer slightly acidic over very acidic foods.
Evolutionary biologists surmise that the need for sour detection to be finely tuned is a two-sided coin: slightly acidic foods can enhance digestion and stimulate saliva production; relative sour-to-sweet taste can signal optimal ripeness of fruit; and extremely sour food, as with bitter taste, is a warning to what not to ingest. However, despite this usefulness, how do animals discern different concentrations ...
Controlling brain states with a ray of light
2021-06-18
The brain presents different states depending on the communication between billions of neurons, and this network is the basis of all our perceptions, memories, and behaviours. It is often considered a "black box", with difficult access for clinicians and researchers, as few limited tools are available to perform accurate and spaciotemporal studies on brain neuronal behaviour. Now, researchers from the Institute for Bioengineering of Catalonia (IBEC) in collaboration with August Pi i Sunyer Biomedical Research Institute (IDIBAPS) and have added some light to the subject: they succeeded for the first time in controlling neuronal activity in the brain using a molecule responsive to light.
The study included participants ...
Vaccination, previous infection, protect against gamma variant in animal model
2021-06-18
MADISON - In early January 2021, travelers returning to Tokyo, Japan, from Amazonas, Brazil, were screened for COVID-19 at the airport. A few days later, the National Institute of Infectious Disease of Japan announced that the travelers had returned with a new variant of the SARS-CoV-2 virus.
That variant, known as gamma, or P.1, led to a deadly surge in COVID-19 cases in Brazil this spring, and has now spread across the world. More than 200 cases have been detected in Wisconsin. Whether current vaccines are as effective against the gamma variant remains unknown.
In a new study using variant virus recovered from one of the original travelers, ...
Managed retreat: A must in the war against climate change
2021-06-18
University of Delaware disaster researcher A.R. Siders said it's time to put all the options on the table when it comes to discussing climate change adaptation.
Managed retreat -- the purposeful movement of people, buildings and other assets from areas vulnerable to hazards -- has often been considered a last resort. But Siders said it can be a powerful tool for expanding the range of possible solutions to cope with rising sea levels, flooding and other climate change effects when used proactively or in combination with other measures.
Siders, a core faculty member in UD's Disaster Research Center, and Katharine J. Mach, associate professor at the University ...
