UrduA study involving 1,156 people from 17 countries finds that, in general, people are more physiologically triggered by negative news compared with positive news, as indicated by measures such as skin conductance levels and heart rate variability, possibly accounting for…

Sequencing assay for single-droplet serum
Researchers developed an RNA sequencing assay called Small-Input Liquid Volume Extracellular RNA Sequencing (SILVER-seq) to detect circulating extracellular RNA in 5-7-microliter droplets of blood serum from liquid biopsies of participants 18-48 years of age, and demonstrated that SILVER-seq can detect…
Sex bias in mammalian specimen collections
Researchers explore sex bias in fossil and museum collections of mammals. Many mammalian species have a 1:1 sex ratio at birth, but previous studies have shown that male specimens are overrepresented in the fossil records of mammoths. To determine whether…
Vintage film shows Thwaites Glacier ice shelf melting faster than previously observed
Newly digitized vintage film has doubled how far back scientists can peer into the history of underground ice in Antarctica, and revealed that an ice shelf on Thwaites Glacier in West Antarctica is being thawed by a warming ocean more…
Study finds increase in women giving TED talks but not ethnic minorities
Women gave more than half of TED talks in the first half of 2017, up from less than one-third in 2006, according to a new study published in Political Research Exchange . But the German research team also found that…
Toxic frogs with weak defenses persist in the gene pool alongside stronger competitors
A multi-national team of evolutionary biologists shows that diversity exists even when expecting oth
Enzyme known for promoting cancer found to also protect healthy cells
UMD researchers discovered that telomerase, which ‘immortalizes’ cancer cells, also prevents tumors
Population structure of Scotland and isles
A study explores the population structure of Scotland and the surrounding isles. Genome analysis has unearthed rich insights into the population histories of England, Wales, and Ireland, which are marked by invasions and migrations. However, the population structures of northern…
Mumps vaccine immunity in young adults
A study finds that in 71 college-age adults, most of whom received measles, mumps, and rubella vaccinations more than 10 years prior to the study, antibody levels against mumps were significantly lower than against rubella, with neutralizing antibody levels against…
New feedback phenomenon found to drive increasing drought and aridity
New study shows an increasingly high probability of more frequent, more extreme concurrent soil drou
Mumps study shows immunity gaps among vaccinated people
College-aged study participants received MMR as children
Anthropogenic disturbances, climate change, and mammalian extinction
A study examines how anthropogenic and climate stressors correlate with local mammalian extinction. Although human activity and global warming are thought to be responsible for the rapid extinction of mammalian species, long-term data on the links is sparse. Zhibin Zhang…
Antarctic ice sheet observations from radar data
Researchers digitized more than 400,000 line-km of archival Antarctic ice-penetrating radar data, originally recorded in the 1970s on 35-mm optical film, and deposited the digitized record into a public archive, enabling the archival data to be compared with modern radar…
Body representation in monkeys’ brains
A study explores the neuropsychological basis for body representation in monkeys. A sense of ownership of one’s own body is a central element of self-consciousness. The psychological and neurological mechanisms underlying this sense can be investigated through illusions, such as…
Concurrent drought and aridity
Climate simulations suggest that land-atmosphere feedbacks involving soil moisture effects on atmospheric temperature and humidity can increase the frequency and intensity of atmospheric aridity, leading to a high probability of concurrent soil drought and extreme aridity in the present climate…
Iris and sclera coloration in great apes
Researchers compared how gray-scale values of sclerae contrasted with iris coloration in 51 bonobos, 50 chimpanzees, and 52 humans, and found that sclerae are lighter than irises in bonobos and humans, whereas in chimpanzees sclerae are darker than irises, suggesting…
Igneous rock record of atmospheric oxygen
Researchers compiled previously published thorium-uranium ratios (Th/U) of more than 29,000 igneous rocks spanning the past 3 billion years and report 2 dramatic decreases occurring at approximately 2.35 and 0.75 billion years ago, consistent with previously established dates for the…
Small venues revitalise city nightlife
Small bars and restaurants have revitalised Adelaide’s nightlife and boosted business in the CBD, created jobs and changed the culture of the city. According to a report by economists from the University of Adelaide’s South Australian Centre for Economic Studies (SACES), more liberal licencing laws have revitalised the city’s nightlife.
