Tropical rainforests are one of the most species-rich areas on earth. Thousands of animal and plant species live there. The smaller microbial protists, which are not visible to the naked eye, are also native to these forests, where they live in the soils and elsewhere. A team of researchers has examined them more closely by analyzing their DNA. They discovered many unknown species, including many parasites, which may contribute to the stability of rainforest ecosystems.
In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks, suggest investigators in a new report.
Researchers have determined the age of the formation of the Amazon River at 9.4 to 9 million years ago with data that convincingly refutes substantial younger estimates.
Can humour on social media help managers find the most appropriate candidates for the job vacancies they hope to fill? Researchers suggest that humorous recruitment campaigns can increase exposure for a given job ad but conversely the approach might lead to flippant applications at which point it might be difficult to separate the serious candidate from an inappropriate one. The team also suggests that choosing a particular social media channel over another may skew the type of applicants they receive for a given job, for better or worse.
A mental hospital-based study in Hanoi, Vietnam looked at if there is a relationship between heat exposure and mental health problems. The results showed significant increase in hospital admissions for mental illnesses during periods of heatwaves, especially during longer periods of heat exposure.
The thinnest, smoothest layer of silver that can survive air exposure could change the way touchscreens and flat or flexible displays are made.
Insulin resistance, caused in part by obesity and physical inactivity, is also linked to a more rapid decline in cognitive performance, new research suggests.
Kids often seek answers from parents, friends and media to better understand their racial identity, suggests new research. The study's researchers sought to explain how ethnic-racial identity exploration and resolution might affect friendship networks among youth in a diverse setting, as well as their peers over time.
Physics is sometimes closer to philosophy when it comes to understanding the universe. Physicists are now attempting to elucidate whether the universe has a resting frame.
States with weaker non-medical exemption policies for vaccinations can reduce the likelihood of a measles outbreak 140 to 190 percent by strengthening them, a new study shows.
Changes that the Rosetta spacecraft discovered on the surface of Comet 67P/Churyumov-Gerasimenko, including the collapse of entire cliffs, were likely driven by seasonal events, according to a new study.
Using a satnav (GPS navigation system) to get to your destination 'switches off' parts of the brain that would otherwise be used to simulate different routes, reveals new research. The study involved 24 volunteers navigating a simulation of Soho in central London while undergoing brain scans.
Researchers have studied how a crucial cancer-related protein plays a role in one of the most aggressive forms of medulloblastoma, the most common malignant brain tumor of childhood.
Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification.
Tim Horton's tops the list: researchers studied data on cardiac arrest locations in Toronto to draft a list of 'top 10' businesses where placing automated external defibrillators would save lives.
Using a new cellular model, innovative gene therapy approaches for the hereditary immunodeficiency Chronic Granulomatous Disease can be tested faster and cost-effectively in the lab for their efficacy. A team of researchers has successfully achieved this using the 'gene-scissor' CRISPR/Cas9 technology. The aim is to treat severely affected patients in the near future using novel approaches.
Older mothers are less likely to punish and scold their children while raising them, and that the children have fewer behavioral, social and emotional difficulties, according to a recent study.
Organic light-emitting devices and printed electronics can be connected to a socket in the wall by way of a small, inexpensive organic converter.
A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space -- is also true for cold helium atoms that can be studied in laboratories. This finding may be a step toward a long-sought quantum theory of gravity and new advances in quantum computing.
'Why do I have to learn this?' It's a common question among youth, but new research suggests students perform much better academically when the answer is provided by their peers rather than their teachers.
