Record UK rainfall in winter 2013-14 caused by tropics, stratosphere and climate warming

Thu, 22/06/2017 - 7:32pm
New research has revealed the causes of the UK's record rainfall and subsequent flooding during the 2013-14 winter. Using carefully tailored atmosphere/ocean model experiments, the research team found that a combination of unusual tropical conditions, the stratospheric polar vortex, and climate warming were behind the extreme rainfall, which led to severe flooding across many parts of the UK.

Seafood poisoning bug thwarts a key host defense by attacking the cell's cytoskeleton

Thu, 22/06/2017 - 7:32pm
The leading cause of acute gastroenteritis linked to eating raw seafood disarms a key host defense system in a novel way: It paralyzes a cell's skeleton, or cytoskeleton.

Flexible wearable electronics use body heat for energy

Thu, 22/06/2017 - 6:31pm
In a proof-of-concept study, engineers have designed a flexible thermoelectric energy harvester that has the potential to rival the effectiveness of existing power wearable electronic devices using body heat as the only source of energy.

Hearing a warning sound turns into fearing it over time, mouse study suggests

Thu, 22/06/2017 - 6:31pm
Changes in lattice-like structures in the brain known as perineuronal nets are necessary to 'capture' an auditory fear association and 'haul' it in as a longer-term memory, an adult mouse model reveals.

How pheromones trigger female sexual behavior

Thu, 22/06/2017 - 6:31pm
A new study showed how a male pheromone in mice enhances sexual behaviors in females -- and how it may enhance a different behavior, aggression, in males -- by identifying distinct neural circuits and neurons that generate a particular behavioral response to specific chemical signals. The findings point to a model for further investigating how sex-specific innate behaviors in living things are controlled.

A 100-year-old physics problem has been solved

Thu, 22/06/2017 - 6:30pm
Researchers have found a way around what was considered a fundamental limitation of physics for over 100 years. They were able to conceive resonant systems that can store electromagnetic waves over a long period of time while maintaining a broad bandwidth. Their study opens up a number of doors, particularly in telecommunications.

How eggs got their shapes

Thu, 22/06/2017 - 6:30pm
The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery. Now, an international team of scientists took a quantitative approach to that question and found that adaptations for flight may have been critical drivers of egg-shape variation in birds.

Tiny nanoparticles offer significant potential in detecting, treating disease new review of work on exosomes

Thu, 22/06/2017 - 6:30pm
Exosomes - tiny biological nanoparticles which transfer information between cells - offer significant potential in detecting and treating disease, the most comprehensive overview so far of research in the field has concluded. Areas which could benefit include cancer treatment and regenerative medicine.

New biomarker assay detects neuroblastoma with greater sensitivity

Thu, 22/06/2017 - 6:30pm
Investigators have developed and tested a new biomarker assay for quantifying disease and detecting the presence of neuroblastoma even when standard evaluations yield negative results for the disease. Researchers provide the first systematic comparison of standard imaging evaluations versus the new assay that screens for five different neuroblastoma-associated genes and determine that the new assay improves disease assessment and provides prediction of disease progression.

How do genes get new jobs? Wasp venom offers new insights

Thu, 22/06/2017 - 6:30pm
A new study describes how four closely related species of parasitic wasps change their venoms rapidly in order to adapt to new hosts, and proposes that co-option of single copy genes may be a common but relatively understudied mechanism of evolution for new gene functions, particularly under conditions of rapid evolutionary change.

A rising star: Researchers dissect the process by which blood vessels shrink, which could have important implications for human health

Thu, 22/06/2017 - 6:30pm
It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.

Localized signaling islands in cells: New targets for precision drug design

Thu, 22/06/2017 - 6:30pm
New research overturns long-held views on a basic messaging system within living cells. Key cellular communication machinery is more regionally constrained within the cell than previously thought. The findings suggest new approaches to designing precision drugs. Localizing drug action at a specific 'address' within the cell could mean fewer side effects in treating cancer, diabetes, heart disease and other serious conditions.

First Chikungunya-infected Aedes aegypti mosquitoes found in Brazil

Thu, 22/06/2017 - 6:30pm
While more than 13,000 cases of Chikungunya viral disease were reported in Brazil in 2015, scientists had never before detected the virus in a captured mosquito in this country. Now, researchers have identified a mosquito -- caught in the Brazilian city of Aracaju -- that's naturally infected with the East-Central-South-African (ECSA) genotype of Chikungunya.
