Experimental COVID-19 vaccine safe, generates immune response
- ScienceDaily
- 20/7/14 23:13
An investigational vaccine, mRNA-1273, designed to protect against SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), was generally well tolerated and prompted neutralizing antibody activity in healthy adults, according to interim results.
COVID-19 may attack patients' central nervous system
- ScienceDaily
- 20/7/14 20:47
A new study finds that depressed mood or anxiety exhibited in COVID-19 patients may be a sign the virus affects the central nervous system. These two psychological symptoms were most closely associated with a loss of smell and taste rather than the more severe indicators of the novel coronavirus such as shortness of breath, cough or fever.
Vision scientists discover why people literally don't see eye to eye
- ScienceDaily
- 20/7/14 20:47
We humans may not always see eye to eye on politics, religion, sports and other matters of debate. And now it turns out we also cannot agree on the location and size of objects in our physical surroundings, according to new research.
Study finds hidden emotions in the sound of words
- ScienceDaily
- 20/7/14 20:47
New research shows that some sound combinations, like those in the word 'virus,' elicit more emotionally intense responses than others. This may play a role in both children's language acquisition and how we might have evolved language in the first place.
Converting female mosquitoes to non-biting males with implications for mosquito control
- ScienceDaily
- 20/7/14 20:47
Researchers have proven that a single gene can convert female Aedes aegypti mosquitoes into fertile male mosquitoes and identified a gene needed for male mosquito flight.
Quantum body scanner? What happens when vector vortex beams meet scattering media
- ScienceDaily
- 20/7/14 20:30
Propagate light through any kind of medium -- be it free space or biological tissue -- and light will scatter. Robustness to scattering is a common requirement for communications and for imaging systems. Structured light, with its use of projected patterns, is resistant to scattering, and has therefore emerged as a versatile tool. In particular, modes of structured light carrying orbital angular...
A Raspberry Pi-based virtual reality system for small animals
- ScienceDaily
- 20/7/14 20:30
The Raspberry Pi Virtual Reality system (PiVR) is a versatile tool for presenting virtual reality environments to small, freely moving animals (such as flies and fish larvae). The use of PiVR, together with techniques like optogenetics, will facilitate the mapping and characterization of neural circuits involved in behavior.
What determines a warbler's colors?
- ScienceDaily
- 20/7/14 20:30
A new study has narrowed down the region of the genome that drives the black color in throat and face of warblers by studying the hybrid offspring produced when two species mate. The hybrids of golden-winged and blue-winged warblers have a mix of coloration from the parent species, which allows researchers to identify which regions of the genome are associated with which color patterns. The study...
Researchers cast doubt on earlier COVID-19 origins study citing dogs as possible hosts
- ScienceDaily
- 20/7/14 20:30
A study published earlier this year claiming the coronavirus may have jumped from dogs to humans is scientifically flawed, offering no direct evidence to support its conclusions, according to a collaborative group of international researchers.
Ups and downs in COVID-19 data may be caused by data reporting practices
- ScienceDaily
- 20/7/14 19:27
As data accumulates on COVID-19 cases and deaths, researchers have observed patterns of peaks and valleys that repeat on a near-weekly basis. A new study reports that those oscillations arise from variations in testing practices and data reporting, rather than from societal practices around how people are infected or treated.
A new path for electron optics in solid-state systems
- ScienceDaily
- 20/7/14 19:27
In combined theoretical and experimental work, physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to engineering quantum-optical phenomena in a variety of materials and devices.
Autism researchers map brain circuitry of social preference
- ScienceDaily
- 20/7/14 19:27
A new study reveals how two key neural circuits dictate the choice between social approach and avoidance. The findings will enable researchers to evaluate social interventions in autism.
Keeping innocent people out of jail using the science of perception
- ScienceDaily
- 20/7/14 18:33
People wrongfully accused of a crime often wait years -- if ever -- to be exonerated. Many of these wrongfully accused cases stem from unreliable eyewitness testimony. Now, scientists have identified a new way of presenting a lineup to an eyewitness that could improve the likelihood that the correct suspect is identified and reduce the number of innocent people sentenced to jail.
Evolution after Chicxulub asteroid impact: Rapid response of life to end-cretaceous mass
- ScienceDaily
- 20/7/14 18:17
The impact event that formed the Chicxulub crater (Yucatán Peninsula, México) caused the extinction of 75% of species on Earth 66 million years ago, including non-avian dinosaurs. One place that did not experience much extinction was the deep, as organisms living in the abyss made it through the mass extinction event with just some changes to community structure.
Tale of the tape: Sticky bits make better batteries
- ScienceDaily
- 20/7/14 18:17
Scientists use an industrial laser to turn adhesive tape into a component for safer, anode-free lithium metal batteries.
Customizable smart window technology could improve energy efficiency of buildings
- ScienceDaily
- 20/7/14 18:17
Scientists combined solar cell technology with a novel optimization approach to develop a smart window prototype that maximizes design across a wide range of criteria.
Experts' high-flying study reveals secrets of soaring birds
- ScienceDaily
- 20/7/14 17:17
New research has revealed when it comes to flying the largest of birds don't rely on flapping to move around. Instead they make use of air currents to keep them airborne for hours at a time. A study has revealed the Andean condor - the world's heaviest soaring bird - actually flaps its wings for one per cent of its flight time.
Wireless aquatic robot could clean water and transport cells
- ScienceDaily
- 20/7/14 17:17
Researchers have developed a tiny plastic robot, made of responsive polymers, which moves under the influence of light and magnetism. In the future this 'wireless aquatic polyp' should be able to attract and capture contaminant particles from the surrounding liquid or pick up and transport cells for analysis in diagnostic devices.
Fleeting flash is most-distant optical afterglow from gamma-ray burst ever detected
- ScienceDaily
- 20/7/14 17:17
Rapid follow-up of the optical afterglow from one of the most distant confirmed short gamma-ray bursts (SGRB), thought to be the merger of two neutron stars, is casting new light on these enigmatic objects. The observations confirmed the object's distance and placed it squarely in the epoch of cosmic high noon, when the Universe was in its ''teenage years'' and rapidly forming stars.

Hammer-on technique for atomic vibrations in a crystal
- ScienceDaily
- 20/7/14 16:12
Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge between gallium and arsenic atoms acts back on their motions via electric interactions.
