The narrative that “Asians are good at math” is pervasive in the United States. Young children are aware of it. College students’ academic performance can be affected by it. And Asian American presidential candidate Andrew Yang has made his mathematical aptitude a feature of his campaign.

For more than a decade, astronomers across the globe have wrestled with the perplexities of fast radio bursts -- intense, unexplained cosmic flashes of energy, light years away, that pop for mere milliseconds.
Despite the hundreds of records of these enigmatic sources, researchers have only pinpointed the precise location of four such bursts.
The number of people who are 80-years-old and older is on the rise, and will account for nearly 10 percent of the whole U.S. population by 2050. Since the lifetime chance for developing high blood pressure is at least 70 percent by age 80, more and more people will be at risk for the health problems that high blood pressure can cause.
BROOKLYN, N.Y. (January 6, 2020) - A study led by researchers from SUNY Downstate Health Sciences University and Oregon Health & Science University, published in the Journal of Infectious Diseases1, showed that, despite successful antiretroviral therapy (ART), antigen specific memory to vaccinations that occurred before HIV infection did not recover, even after immune reconstitution.
Astronomers in Europe, working with members of Canada's CHIME Fast Radio Burst collaboration, have pinpointed the location of a repeating fast radio burst (FRB) first detected by the CHIME telescope in British Columbia in 2018. The breakthrough is only the second time that scientists have determined the precise location of a repeating source of these millisecond bursts of radio waves from space.
INFORMS Journal Management Science New Study Key Takeaways:
Nearly 80% of bike-share usage comes from areas within 1,000 feet of the stations.
A 10% increase in bike availability would increase ridership by more than 12%.
System use is more likely to be affected by bike availability rather than dock availability.
For the first time, coyotes (Canis latrans) and crab-eating foxes (Cerdocyon thous) are occurring together. According to a recent study by researchers at the Smithsonian Tropical Research Institute (STRI) and collaborating institutions, deforestation along the Mesoamerican Biological Corridor may be the reason why canid species from North and South America ended up living side by side in eastern Panama, far from their original ranges.
Although most cotton is grown in floodplain soils in the Mississippi Delta region, a large amount of cotton is also grown under no-till systems on upland soils that are vulnerable to erosion and have reduced organic matter. There are much lower levels of cotton residue in these systems, which limits the effectiveness of the no-till approach to improve soil health.
URBANA, Ill. - Like most plants, soybeans pair up with soil fungi in a symbiotic mycorrhizal relationship. In exchange for a bit of sugar, the fungus acts as an extension of the root system to pull in more phosphorus, nitrogen, micronutrients, and water than the plant could on its own.
Mycorrhizal fungi occur naturally in soil and are commercially available as soil inoculants, but new research from the University of Illinois suggests not all soybean genotypes respond the same way to their mycorrhizal relationships.
Energy - Whatever the weather
To better determine the potential energy cost savings among connected homes, researchers at Oak Ridge National Laboratory developed a computer simulation to more accurately compare energy use on similar weather days.
About twenty percent of confirmed pregnancies end in miscarriage, most often in the first trimester, for reasons ranging from infection to chromosomal abnormality. But some women have recurrent miscarriages, a painful process that points to underlying issues.
That size, shape and structure of organisms can evolve at different speeds is well known, ranging from fast-evolving adaptive radiations to living fossils such as cichlids or coelacanths, respectively.
A team lead by biologists at the Natural History Museum (University of Oslo) has uncovered a group of species in which change in appearance seems to have been brought to a complete halt.
The tiny annelid worms belonging to the genus Stygocapitella live in sandy beaches around the world. In their 275-million-year-old history the worms have evolved ten distinct species.
The World Health Organization has estimated more than 340 million children and adolescents ages 5-19 are overweight or obese, and the epidemic has been linked to more deaths worldwide than those caused by being underweight.
The Centers for Disease Control recently reported an estimated 1 in 5 children in the United States, ages 12-18, are living with prediabetes -- increasing their risk of developing type 2 diabetes as well as chronic kidney disease, heart disease and stroke.
The "Star-Spangled Banner" stirs pride. Ed Sheeran's "The Shape of You" sparks joy. And "ooh là là!" best sums up the seductive power of George Michael's "Careless Whispers."
Scientists at the University of California, Berkeley, have surveyed more than 2,500 people in the United States and China about their emotional responses to these and thousands of other songs from genres including rock, folk, jazz, classical, marching band, experimental and heavy metal.
A UCLA-led study revealed a new way to predict which patients with "stable" heart failure -- those who have heart injury but do not require hospitalization -- have a higher risk of dying within one to three years.
Although people with stable heart failure have similar characteristics, some have rapid disease progression while others remain stable. The research shows that patients who have higher levels of neuropeptide Y, a molecule released by the nervous system, are 10 times more likely to die within one to three years than those with lower levels of neuropeptides.
