Binary stars are all around us, new map of solar neighborhood shows
A UC Berkeley doctoral student has mined the most recent Gaia survey for all binary stars near Earth and created a 3D atlas of 1.3 million of them. The last local survey included about 200 binary pairs. With such census data, astronomers can conduct statistical analyses on binary populations. For pairs that contain white dwarfs, it's possible to determine the age of their main-sequence companion, and thus of any exoplanets around them. (2021-02-22)

Why does love of bargain hunting run in families?
Headlines like ''Black Friday Shoppers Trampled in New York'' and popular television shows such as ''Extreme Couponing'' remind us how crazy consumers can get about retail sales promotions. This enthusiasm for getting bargains has been termed ''deal proneness.'' (2021-02-09)

Two anti-viral enzymes transform pre-leukemia stem cells into leukemia

Perovskite materials: Neutrons show twinning in halide perovskites
Solar cells based on hybrid halide perovskites achieve high efficiencies. These mixed organic-inorganic semiconductors are usually produced as thin films of microcrystals. An investigation with the Laue camera at the neutron source BER II could now clarify that twinning occurs during crystallisation even at room temperature. This insight is helpful for optimising production processes of halide perovskites. (2020-10-13)

Alcohol use changed right after COVID-19 lockdown
One in four adults reported a change in alcohol use almost immediately after stay-at-home orders were issued: 14% reported drinking more alcohol and reported higher levels of stress and anxiety than those who did not drink and those whose use stayed the same. The 11% who decreased their drinking also had higher levels of stress and anxiety--suggesting that any change in alcohol use may be associated with mental health issues. (2020-10-13)

Evolutionary and heritable axes shape our brain
Every region has its place in the brain. However, it has been unclear why brain regions are located where they are. Now, scientists at the Max Planck Institute for Human Cognitive and Brain Sciences have defined two main axes along which brain regions are genetically organized, stretching from posterior to anterior and inferior to superior in the brain. These axes are mainly shaped by genes and evolution. (2020-09-28)

Pair of massive baby stars swaddled in salty water vapor
Using ALMA, astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk which includes molecules of sodium chloride, commonly known as table salt, and heated water vapor. Analyzing the radio emissions from the salt and water, the team found that the disks are counter rotating. It is promising that salt is an excellent marker to explore the immediate surroundings of giant baby stars. (2020-09-25)

A direct link between smoking and fatal brain haemorrhage demonstrated by a Finnish study
According to a recently published study of Finnish twins, smoking most likely causes a significant share of all cases of subarachnoid haemorrhage, the most fatal type of cerebrovascular disturbances. In the study, smoking was identified as the explanation as to why only one twin in pairs of twins develops a fatal brain haemorrhage. The finding is the first proof of an actual causality between smoking and subarachnoid haemorrhage. (2020-09-17)

Smoking linked to bleeding in the brain in large, long-term study of twins
Researchers in Finland found a link between smoking and subarachnoid hemorrhage (SAH), a type of bleeding stroke, in a study of more than 16,000 pairs of twins over 42 years. The study found that bleeding in the brain can be explained to a greater degree by environmental risk factors, such as smoking, than by genetic influence. (2020-09-17)

Perceiving the flavor of fat: A Monell Center twins study
Most people would agree that the pleasure of some foods stems in part from its fat content. New research, led by the Monell Chemical Senses Center, has now found that liking of fatty food is more complex than its fat content alone -- it could also be related to inborn genetic traits of the consumer related to fat perception. (2020-07-13)

The risk of cerebral palsy linked to IVF has more than halved in the past two decades
Fifteen years ago a large population study from Denmark found a significantly increased risk of cerebral palsy in infants born as a result of assisted reproduction. Although the absolute risk was small, such studies at this time made cerebral palsy the greatest developmental birth defect risk associated with IVF, and a concern in its overall safety profile. (2020-07-07)

BCN MedTech presents an automatic method to detect and segment the intrauterine cavity
Twin-to-twin transfusion syndrome (TTTS) occurs in around 10-15% of pregnancies with twins that share the same placenta. Typically, this syndrome appears before 24 weeks' gestation due to abnormal vascular communications located on the surface of the placenta. As a result, blood circulation is not balanced between the two twins, dramatically decreasing their chances of survival. (2020-05-22)

Using digital twins to design more sustainable cities
Over the past several years, a collaboration at HLRS has been developing a digital twin of Herrenberg, a small city just outside of Stuttgart, Germany. The Herrenberg study has already provided valuable information for city planners and government officials in the state of Baden-W├╝rttemberg, and paves the way for improving the model to include additional kinds of data. (2020-05-07)

Weighing more than your twin at birth may predict better achievement at school
Research has shown that children who are born at a low birthweight are less likely to do well in school and more likely to live in lower-income neighborhoods as adults. A new study of twins looked at the effect of birthweight on children's cognitive and socioemotional outcomes at 4 years old, taking into account families' socioeconomic status (SES). (2020-01-28)

Persistence of gut microbial strains in twins, living apart after cohabitating for decades
Using a genomics strain-tracking bioinformatics tool, researchers investigated whether shared bacterial strains remain stable and resilient to changes in diet or environment after adult twins -- who had lived together for decades -- began to live apart. The study analyzed two metagenomic sequencing databases from pairs of twins -- one for children who were still living together and the other from adult twins, ages 36 to 80, who then lived apart for periods from one to 59 years. (2020-01-08)

Adolescents' view of family social standing correlates with mental health, life outcomes
Young people's view of their family's social status was more strongly associated with their mental health and readiness for future education and work than how much money, education or occupational prestige their parents have, according to new research led by the University of California, Irvine. By 18, youths who rated their family as having a higher place in society had fewer difficulties negotiating the transition to adulthood, independent of the objective position of the family. (2020-01-06)
