The increased global consumption of food means that there is an increasing yield gap between crop production and crop usage. To help tackle this issue, a team of scientists has used advanced mathematical modelling techniques to understand the precise role soil structure plays in water uptake.
Findings from a new global study suggest that estimates of gender-based violence prevalence based on health systems data or on police reports may underestimate the actual total prevalence by 11- to 128-fold.
Long-term use of commonly prescribed heartburn and ulcer medications is linked to a higher risk of vitamin B12 deficiency, according to a new study.
If recent news that researchers observed the largest gamma ray burst ever has you nervous about getting blasted into extinction, the researchers themselves say chances of that are exceedingly rare.
An experimental compound is capable of significantly reducing joint inflammation in animal models of rheumatoid arthritis.
Strangers often stop to ask Bob Seeman why he wears a padded glove on his left hand. So he hands out a card with a link to a YouTube video, which tells the extraordinary story of how Seeman’s left arm was reattached after it was nearly completely severed in a tow truck accident.
NASA's Juno Spacecraft Hears Amateur Radio Operators Say 'Hi': Message was first-of-its-kind for an interplanetary spacecraft
In a first-of-its-kind activity for an interplanetary spacecraft, thousands of amateur (ham) radio operators around the world were able to say “Hi” to NASA’s Juno spacecraft Oct. 9 as it swung past Earth on its way to Jupiter.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) satellite, scheduled for launch in 2015, will demonstrate how accurate and wide-ranging measurements of Earth’s outgoing radiation can be made with a remarkably small instrument.
Mothers get all the attention. But a study suggests that the father’s diet before conception may play an equally important role in the health of their offspring. It also raises concerns about the long-term effects of current Western diets and of food insecurity.
Scientists recently recorded the lowest temperatures on Earth at a desolate and remote ice plateau in East Antarctica, trumping a record set in 1983 and uncovering a new puzzle about the ice-covered continent.
A new review highlights new developments in understanding the health effects of silica, and calls for action to reduce illness and death from silica exposure at work.
An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, astronomers have found, and knowing that may help in the search for potentially habitable worlds.
Researchers studying speciation of butterfly orchids on the Azores have been startled to discover that the answer to a long-debated question "Do the islands support one species or two species?" is actually "three species". Hochstetter's Butterfly-orchid, newly recognized following application of a battery of scientific techniques and reveling in a complex taxonomic history worthy of Sherlock Holmes, is arguably Europe's rarest orchid species. Under threat in its mountain-top retreat, the orchid urgently requires conservation recognition.
In the first study of its kind, two researchers have used popular music to help severely brain-injured patients recall personal memories.
The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell. Scientists have coordinated a study on the mechanic properties of viruses that have improved their understanding, so much that they were able to make conjectures on the behavior of still little-known viruses.
Apply heat and stir; an expanding universe can emerge in a remarkably simple way, say scientists. When soup is heated, it starts to boil. When time and space are heated, an expanding universe can emerge, without requiring anything like a "Big Bang." This phase transition between a boring empty space and an expanding universe containing mass has now been mathematically described by researchers. The idea behind this result is a remarkable connection between quantum field theory and Einstein's theory of relativity.
A study by researchers into the effects of sugars on our oral health recommends cutting down on the sweet additive as part of a global initiative to reduce tooth decay.Since 1990 the World Health Organization (WHO) has recommended that intake of “free sugars” should be less than 10% of total energy (calorie) intake. Free sugars are sugars that are added to foods by the manufacturer, cook, or consumer; plus those naturally present in honey, syrups, fruit juices and fruit concentrates.
Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers have found. The discovery may shed light on the pathology of septic shock.
Researchers have found evidence of diverse mineralogy in the moon's South Pole Aitken basin, a giant crater left by an impact 4 billion years ago. The findings could mean that some minerals dug up during that ancient impact remain intact within the basin. If that's true, then the basin could hold vital clues about the makeup of the moon's mantle.
In the first 300 days of the Mars Science Laboratory's surface mission, the Curiosity rover cruised around the planet's Gale Crater, collecting soil samples and investigating rock structures while the onboard Radiation Assessment Detector made detailed measurements of the radiation environment on the surface of Mars. The radiation on Mars is much harsher than on Earth for two reasons: Mars lacks a global magnetic field and the Martian atmosphere is much thinner than Earth's, providing little shielding to the surface.
