Rewiring plant defence genes to reduce crop waste

Dom, 06/17/2018 - 22:00
Plants could be genetically rewired to better resist disease, helping safeguard crop yields worldwide according to new research by the universities of Warwick and York. Defensive feedback control system developed enables plants to strengthen their defenses to withstand attack by re-wiring existing gene connectionsThe system uses same approach as aircraft autopilots use to counteract turbulence.

Odors are perceived the same way by hunter-gatherers and Westerners

Dom, 06/17/2018 - 22:00
Previous research has shown the hunter-gatherer Jahai are much better at naming odors than Westerners. They even have a more elaborate lexicon for it. New research by language scientist Asifa Majid of Radboud University shows that despite these linguistic differences, the Jahai and Dutch find the same odors pleasant and unpleasant.

Using gold nanoparticles to trigger sequential unfolding of 3D structures

Dom, 06/17/2018 - 22:00

A new study from researchers at Michigan Medicine explores links between chronic joint inflammation and cognitive impairment.

New material for splitting water

Dom, 06/17/2018 - 22:00
Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water, according to research in Applied Physics Letters.

Nature programmes could put a spring in your step

A new study shows that watching films set in a natural environment boosts body image.

When consumers don't want to talk about what they bought

Dom, 06/17/2018 - 22:00
One of the joys of shopping for many people is the opportunity to brag about their purchases to friends and others. But new research found one common situation in which people would rather not discuss what they just bought: when they're feeling like money is a little tight. In a series of studies, researchers found that consumers who felt financially constrained didn't want to talk about their purchases, large or small, with friends or strangers.

Study examines first birth cohort to receive HPV vaccine: The vaccine works

Dom, 06/17/2018 - 22:00
Girls in the first birth cohort to be offered and receive the HPV vaccine showed a lower degree of dysplasia which may eventually lead to cervical cancer than a birth cohort from 1983. This is the conclusion of a new study conducted by researchers at the University of Copenhagen, who have been the first to study the vaccine's effect on the general population.

Research finds new way to determine protection of Men B vaccine against different strains

This approach is being assessed by Public Health England for its potential to routinely test all meningococcal disease cases.

New radiological procedure for the diagnosis of liver disease

Dom, 06/17/2018 - 22:00
Researchers from Charité -- Universitätsmedizin Berlin have successfully tested a new technology for use in the assessment of overweight adolescents with liver disease. Known as 'time-harmonic elastography' (THE), the technology enables physicians to determine the disease's severity without having to resort to invasive liver biopsies. The results of this research have been published in Radiology.

'Be personal and appreciative': Research shows effective responses to online feedback

Dom, 06/17/2018 - 22:00
As more patients leave feedback on online platforms including social media, new research shows how health and social care organisations can offer value in their response. The study was led by University of Plymouth researcher Rebecca Baines and colleagues in collaboration with James Munro at online platform Care Opinion, and they will be sharing the full findings at a webinar on Thursday, June 21.

Trojan Horse: How a killer fungus unleashes meningitis and brain infection

Dom, 06/17/2018 - 22:00
In a world first, Australian researchers have revealed how a deadly fungus and primary cause of life-threatening meningitis exploits the immune system like a 'Trojan Horse' to promote infection.

Chemists achieve major milestone of synthesis: Remote chiral induction

Dom, 06/17/2018 - 22:00

Bolder targets needed to protect nature for people's sake

Dom, 06/17/2018 - 22:00
University of Queensland researchers have found that humanity is at risk without more diverse, ambitious and area-specific conservation targets. Associate Professor Martine Maron, Dr. Jeremy Simmonds and Professor James Watson from UQ's School of Earth and Environmental Sciences say current targets lack the scope required to support the critical services that nature provides.
