New invention: The oxygen-ion battery
2023-03-22
Lithium-ion batteries are ubiquitous today - from electric cars to smartphones. But that does not mean that they are the best solution for all areas of application. TU Wien has now succeeded in developing an oxygen-ion battery that has some important advantages. Although it does not allow for quite as high energy densities as the lithium-ion battery, its storage capacity does not decrease irrevocably over time: it can be regenerated and thus may enable an extremely long service life.
In addition, oxygen-ion batteries can be ...

Bilayer PET/PVDF substrate-reinforced solid polymer electrolyte improves solid-state lithium metal battery performance
2023-03-22
Effective energy storage is paramount to society’s transition to renewable energy. Lithium metal batteries (LMBs) have the potential to double the amount of energy stored in a single charge compared to current lithium ion batteries (LIBs), but lithium dendrite growth and electrolyte consumption in current LMB technologies are hindering battery performance. Substrates for solid polymer electrolytes (SPEs) offer a potential solution to current LMB limitations, but SPEs require their own optimization prior to integration into all-solid-state LMB (ASSLMB) systems.

New survey finds COVID-19 pandemic changed public’s view of obesity
2023-03-22
Nearly a third of Americans (29%) say COVID-19 made them more worried than ever about having obesity prompting about 28 million people to consider weight-loss methods they hadn’t thought about before the pandemic began, including nearly 6.4 million thought about turning to either weight-loss surgery or taking prescription anti-obesity drugs for the first time, according to a new survey whose findings were published online in the peer-reviewed journal, Surgery for Obesity and Related Diseases (SOARD).
Another nearly 1 in 5 people (18%) said they were more likely to initiate a discussion about their weight with their physician specifically because ...
Searching for life with space dust
2023-03-22
Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near future, or even now.
When you hear the words vacuum and dust in a sentence, you may groan at the thought of having ...
Hunting Venus 2.0: Scientists sharpen their sights
2023-03-22
With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they’ve ever been to finding an analog of Earth’s “twin.”
If they succeed in locating one, it could reveal valuable insights into Earth’s future, and our risk of developing a runaway greenhouse climate as Venus did.
Scientists who wrote the paper began with more than 300 known terrestrial planets orbiting other stars, called exoplanets. They whittled the list down to the five most likely to ...
New research reveals a potential mechanism for how coffee may reduce the risk of type 2 diabetes
2023-03-22
New scientific research investigates inflammation and insulin resistance in habitual coffee drinkers to understand how coffee may reduce the risk of type 2 diabetes (T2D), mediated by inflammatory biomarkers in the body 1.
Drinking just one additional cup of coffee per day was associated with a 4-6% lower risk of T2D among participants in two large prospective cohort studies, which was partly explained by lower levels of inflammation1.
Experts consider consuming up to 400mg of caffeine (3-5 cups of coffee) per day to be a moderate and safe amount for most adults. For pregnant or lactating women, caffeine intake should be reduced to 200mg per day2.
These results further support previous ...
Big firms are failing to reduce unconscious bias against disabled people
2023-03-22
Working for a big company or in an HR role does not lower the likelihood of showing unconscious bias against disabled people at work, a new study finds.
Researchers say this is ‘surprising’ because of the money many large firms spend on EDI and unconscious bias training – in 2017 up to $8bn in the US alone – and the fact HR professionals are often specifically trained in EDI issues.
The research, a collaboration between the University of Exeter’s Business School and Medical ...
Does birth by cesarean section affect children’s academic performance and intelligence?
2023-03-22
In a study of Danish children born between 1978–2000, chances of graduating from lower and upper secondary education were significantly lower for children born by cesarean section (CS). However, differences in grade point averages and intelligence scores were very small. The study, which is published in Acta Obstetricia et Gynecologica Scandinavica, also found that males born by CS had a lower likelihood of appearing before a conscription board for drafting into the military.
In Denmark, most students are 6–16 years old while in lower secondary education (LSE) and 16–17 years old when initiating ...
Can moderate dietary salt restriction help patients with hypertension?
2023-03-22
Results from a clinical trial published in the Journal of Internal Medicine reveal several health benefits of moderate salt restriction in patients on standard medical treatment for primary aldosteronism.
Primary aldosteronism—a condition in which the adrenal glands make too much of the hormone aldosterone—is a common cause of secondary hypertension. The combination of aldosterone excess and high dietary salt intake leaves affected patients with a higher risk of cardiovascular disease than patients with hypertension ...
How fisheries threaten seals and sea lions in South America
2023-03-22
Seals, sea lions, and fur seals are at risk from interactions with fisheries and aquaculture, as they can become entangled in nets or cages, and drown. In a study published in Mammal Review, investigators analyzed research from the last 25 years on operational and biological interactions between these marine mammals and fisheries and aquaculture activities in South American waters.
The authors found that two species are primarily involved in interactions in many countries: the South American sea lion Otaria flavescens and the South American fur seal Arctocephalus australis. ...
Does care during pregnancy differ based on patient race in the United States?
2023-03-22
In an analysis of perinatal care provided in the United States, investigators found few differences by race for care that was based on guidelines or expert recommendations; however, discretionary care (for which professional recommendations or guidelines do not exist) varied by race.
The analysis, which is published in Birth, included information from the electronic health records for 7,056 women who delivered infants within a large hospital system between 2012 and 2018. Compared with Non-Hispanic white women, Non-Hispanic Black women were ...
Are there sex-based differences in brain development during early childhood?
2023-03-22
New research published in Human Brain Mapping reveals sex differences and developmental changes in the brain’s white matter—which provides communication between different parts of the brain—in healthy, typically developing infants and 5-year-olds.
The results, which highlighted sexual dimorphism in brain structure during development with significant detectable differences in multiple regions at the age of 5 years, agree with prior studies showing earlier brain development in females.
Also, changes in white matter asymmetry patterns occurred during early childhood, and in 5-year-olds the pattern already resembled adult-like patterns.
“We observed sex differences ...
Boosting the effects of a particular microRNA may benefit patients with cervical cancer
2023-03-22
Dysregulation of microRNAs, which are molecules involved in controlling gene expression, can promote tumor formation and progression. A study in The FASEB Journal found that the miR-145 microRNA can suppress the growth of cervical cancer cells.
miR-145 was expressed at lower than normal levels in human cervical cancer cells, and lower levels correlated with more advanced clinical stages of cervical cancer in patients.
Experiments in cells and mice revealed the mechanisms behind miR-145 effects and pointed to potential targets that could be ...
