Earth has a hot new neighbour -- and it's an astronomer's dream

A rocky planet discovered in the Virgo constellation could change how we look for life in the universe

Earth has a hot new neighbour -- and it's an astronomer's dream
2021-03-04
(Press-News.org) A newly discovered planet could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows.

The planet, called Gliese 486b (pronounced Glee-seh), is a 'super-Earth': that is, a rocky planet bigger than Earth but smaller than ice giants like Neptune and Uranus. It orbits a red dwarf star around 26 light-years away, making it a close neighbour - galactically speaking.

With a piping-hot surface temperature of 430 degrees Celsius, Gliese 486b is too hot to support human life. But studying its atmosphere could help us learn whether similar planets might be habitable for humans - or if they're likely to hold other signs of life.

The findings are published today in END

A parental paradox for Black girls in the justice system

2021-03-04
COLUMBUS, Ohio - For Black girls in the juvenile justice system, attention from a caregiver might amount to too much of a bad thing, a recent study suggests. Though parental attentiveness would generally be considered beneficial to troubled youths, the finding hints at the possibility that a history of trauma in a household's adults may filter down to younger generations, researchers say. The study, examining how family and peer social support influenced post-traumatic stress disorder (PTSD) symptoms in Black girls who were in detention, found that lower self-esteem, less optimism about the future and higher negative behaviors by peers were associated with greater PTSD symptoms in these girls. But one more factor also correlated with those symptoms: a higher level of caregiver support. "This ...

Moms need guidance on what to eat when their breastfeeding infant has a food allergy

2021-03-04
ARLINGTON HEIGHTS, IL (March 4, 2021) - Many new mothers with infants want very much to breastfeed as it is the gold standard for early nutrition. What to do when you find out your young child has a food allergy, and you are breastfeeding? A new study in Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), found that more than 28% of the women were given no guidance on whether they could eat the same food their breastfeeding child was allergic to. "We found that guidance from healthcare practitioners for breastfeeding mothers in this situation ...

Field study shows icing can cost wind turbines up to 80% of power production

Field study shows icing can cost wind turbines up to 80% of power production
2021-03-04
AMES, Iowa - Wind turbine blades spinning through cold, wet conditions can collect ice nearly a foot thick on the yard-wide tips of their blades. That disrupts blade aerodynamics. That disrupts the balance of the entire turbine. And that can disrupt energy production by up to 80 percent, according to a recently published field study led by Hui Hu, Iowa State University's Martin C. Jischke Professor in Aerospace Engineering and director of the university's Aircraft Icing Physics and Anti-/De-icing Technology Laboratory. Hu has been doing laboratory studies of turbine-blade icing for about 10 years, including performing experiments ...

Study aims to help governments maximize profits from oil and gas auctions

2021-03-04
HOUSTON - (March 4, 2021) - Federal and state governments auction leases to oil and gas companies to extract natural resources from public land. A revamp of the auction system -- utilizing a new model developed by a Rice University economist -- could lead to more competitive bids and, ultimately, more money for governments. Yunmi Kong, an assistant professor of economics at Rice and the study's author, discussed her model in "Sequential Auctions with Synergy and Affiliation Across Auctions." The article appeared in the January 2021 edition of the Journal of Political Economy. "Much of the oil- and gas-producing ...

Scientists explore the action mechanism of a new antibiotic

Scientists explore the action mechanism of a new antibiotic
2021-03-04
Scientists from Skoltech and MSU have investigated antibiotic nybomycin that could prove effective against bacteria resistant to other antibiotics. Their research was published in the journal Antimicrobial Agents and Chemotherapy. All bacterial cells contain topoisomerases, an important group of enzymes that help deal with spatial difficulties stemming from bacterial cell division associated with circular DNA replication. Topoisomerases can be of two types, I and II, depending on breaks they produce in DNA (one strand or double strand). Type II often acts as a target for antibiotics, including fluoroquinolones (FQ), a common group of antibiotics that comprises levofloxacin, ciprofloxacin, and others. Unfortunately, bacteria easily acquire resistance to ...

Failing to see the forest for the trees may prevent better cardiovascular outcomes

2021-03-04
Managing single risk factors like blood pressure rather than looking at overall risk may be wasting scarce resources in countries where cardiovascular disease (CVD) is on the rise, according to a new study. Researchers looked at country-specific levels of cardiovascular risk, associations with socio-demographic factors and whether WHO guidelines on the use of blood pressure medication were being followed across 45 low-income and middle-income countries (LMICs). They found a higher risk of CVD in lower educated and non-employed people, an overuse of medicines in people at lower levels of CVD risk and an underuse of medicines in people at higher risk across ...

Dramatic decline in western butterfly populations linked to fall warming

Dramatic decline in western butterfly populations linked to fall warming
2021-03-04
Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report to be published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s. "The monarch population that winters along the West Coast plummeted from several hundred thousand just a few years ago to fewer than 2,000 this past year," said Katy Prudic, an assistant professor of citizen and data science in the University of Arizona School of Natural Resources and the Environment and a co-author of the report. "Essentially, the western monarch is on the brink of extinction, but what's most unsettling is they are situated in the middle of the pack, so to speak, ...

COVID-19 screening: A new model for assessing the efficiency of group testing

2021-03-04
How best to evaluate the performance of a group testing strategy for the SARS-CoV-2 virus, which involves pooling samples from multiple individuals in order to conduct a single RT-PCR test on the whole group? To do precisely that, scientists from the CNRS, l'université Grenoble Alpes, and l'université Sorbonne Paris Nord1 have developed a model that evaluates the efficiency of such tests. Their theoretical study accounts for both dilution effect and the detection limits of the RT-PCR test, in an effort to assess the number of potential false negatives based on pooled sample size, to optimize group size thereby minimizing epidemic risk, and finally to more accurately determine ...

High strength through hierarchy

High strength through hierarchy
2021-03-04
The research group presents its findings in the current issue of the journal Science. When the Eiffel Tower was inaugurated in 1889, it was considered a technical marvel. Its artful and delicate arrangement of large and small iron girders provided extraordinary stability and made sure it became the world's tallest building at the time by a long shot. "Hierarchical" is what experts call the engineering approach of an open array of larger beams braced by smaller ones. For several years now, material science researchers have tried to transfer this efficient approach to the internal microstructure of materials, for example by using 3D printers that can replicate engineering truss ...

A super-Earth is discovered which can be used to test planetary atmosphere models
2021-03-04
During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice and gas, thanks to the construction of astronomical instruments designed specifically for planet searches. Also, using a combination of different observing techniques they have been able to determine a large numher of masses, sizes, and hence densities of the planets, which helps them to estimate their internal composition and raising the number of planets which have been discovered outside the Solar System. However, to study the atmospheres of the rocky planets, which would made it possible to characterize fully those exoplanets which are similar to Earth, is extremely difficult with currently available ...
