Gasp! First audio map of oohs, aahs and uh-ohs spans 24 emotions

Gasp! First audio map of oohs, aahs and uh-ohs spans 24 emotions

Ooh, surprise! Those spontaneous sounds we make to express everything from elation (woohoo) to embarrassment (oops) say a lot more about what we're feeling than previously understood, according to new research from the University of California, Berkeley.Proving that a sigh is not just a sigh, UC Berkeley scientists conducted a statistical analysis of listener responses to more than 2,000 nonverbal exclamations known as "vocal bursts" and found they convey at least 24 kinds of emotion. Previous studies of vocal bursts set the number of recognizable emotions closer to 13.The results, recently...

Study reveals unsettling multidrug antibiotic resistance in remote Arctic soil microbes

Study reveals unsettling multidrug antibiotic resistance in remote Arctic soil microbes

LAWRENCE -- A University of Kansas geologist's work in the remote High Arctic of Norway has exposed the startling global spread of antibiotic-resistant microbes -- including multidrug-resistant "superbugs" -- that could have dire implications for human health worldwide.Jennifer Roberts, professor and chair of geology at KU, began by investigating the microbial geochemistry of thawing permafrost and its release of methane, a powerful greenhouse gas that speeds global climate change.But follow-up analysis of the soil samples Roberts collected in the Kongsfjorden region of Svalbard, Norway,...

Healthy diet can ease symptoms of depression

Healthy diet can ease symptoms of depression

An analysis of data from almost 46,000 people has found that weight loss, nutrient boosting and fat reduction diets can all reduce the symptoms of depression.Dr Joseph Firth, an Honorary Research fellow at The University of Manchester and Research Fellow at NICM Health Research Institute at Western Sydney University, says existing research has been unable to definitively establish if dietary improvement could benefit mental health.But in a new study published in Psychosomatic Medicine, Dr Firth and colleagues brought together all existing data from clinical trials of diets for mental health...

Ice Age survivors or stranded travellers? A new subterranean species discovered in Canada

Ice Age survivors or stranded travellers? A new subterranean species discovered in Canada

The discovery of a new to science species of rare and primitive arthropod from the depths of a cave that was covered by a thick ice sheet until recently is certain to raise questions. In their study, in the open-access journal , entomologist Alberto Sendra and local caver Craig Wagnell describe a new species of cave-dwelling, insect-like campodeid dipluran from the island of Vancouver (Canada) and discuss its origin.According to the study, the dipluran's presence could either mean that terrestrial arthropods have indeed been able to survive within the deep subterranean habitats during the...

Hubble reveals dynamic atmospheres of Uranus, Neptune

Hubble reveals dynamic atmospheres of Uranus, Neptune

During its routine yearly monitoring of the weather on our solar system's outer planets, NASA's Hubble Space Telescope has uncovered a new mysterious dark storm on Neptune and provided a fresh look at a long-lived storm circling around the north polar region on Uranus.Like Earth, Uranus and Neptune have seasons, which likely drive some of the features in their atmospheres. But their seasons are much longer than on Earth, spanning decades rather than months.The new Hubble view of Neptune shows the dark storm, seen at top center. Appearing during the planet's southern summer, the feature is...

How a fungus can cripple the immune system

How a fungus can cripple the immune system

It is everywhere - and it is extremely dangerous for people with a weakened immune system. The fungus Aspergillus fumigatus occurs virtually everywhere on Earth, as a dark grey, wrinkled cushion on damp walls or in microscopically small spores that blow through the air and cling to wallpaper, mattresses and floors. Healthy people usually have no problem if spores find their way into their body, as their immune defence system will put the spores out of action. However, the fungus can threaten the lives of people with a compromised immune system, such as AIDS patients or people who are...

Green water-purification system works without heavy metals or corrosive chemicals

Green water-purification system works without heavy metals or corrosive chemicals

Scientists at the Institute of Process Engineering (IPE) at the Chinese Academy of Sciences in Beijing and Yangzhou University (YZU) in Jiangsu have developed an effective and energy-efficient technique for purifying water by using graphitic carbon nitride sheets.Their prototype, presented February 7 in the journal Chem, purified pathogen-rich water in 30 min, killing over 99.9999% of bacteria, such as E. coli, meeting China's requirements for clean drinking water. Unlike metal-based photocatalytic disinfectants, it achieved this standard without leaving behind secondary pollution or...

Astrocytes Converted to Neurons

Astrocytes Converted to Neurons

A simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer's disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three, molecules that could convert glial cells--which normally provide support and insulation for neurons--into new neurons. A paper describing the approach appears online in the journal on February 7, 2019."The biggest problem for brain repair is that neurons don't regenerate after brain damage, because they don't divide," said Gong Chen,...

Positive thinking during pregnancy could help children's ability in math and science

Positive thinking during pregnancy could help children's ability in math and science

Using data from Bristol's Children of the 90s study the research is one of a series from the University of Bristol, that examines a parental personality attribute known as the 'locus of control'. This is a psychological measure of how much someone believes that they have control over the outcome of events in their life or whether external forces beyond their control dictates how life turns out.Those with an external locus of control would believe there is little point in making an effort as what happens to them is due to luck and circumstances, in contrast with internally controlled people...

Cannabinoid compounds may inhibit growth of colon cancer cells

Cannabinoid compounds may inhibit growth of colon cancer cells

Medical marijuana has gained attention in recent years for its potential to relieve pain and short-term anxiety and depression. Now, Penn State College of Medicine researchers say some cannabinoid compounds may actually inhibit the growth of colon cancer cells in the lab.The researchers tested the effects of synthetic cannabinoid compounds on colon cancer cells in an experiment in test tubes. While the compounds most commonly associated with cannabis -- THC and CBD -- showed little to no effect, 10 other compounds were effective at inhibiting cancer cell growth.Kent Vrana, chair of the...
