Study finds graspable objects grab attention more than images of objects do

Mié, 12/13/2017 - 23:00
Jacqueline Snow, with the University of Nevada, Reno's College of Liberal Arts, and her graduate students, Michael Gomez and Rafal Skiba, recently published findings of their research, "Graspable objects grab attention more than images do." They studied how humans allocate attention to different objects in a scene and examined whether real objects compete more strongly for attention and manual responses compared to matched computerized 2-D and 3-D images of the same objects.

Finding a lethal parasite's vulnerabilities

Mié, 12/13/2017 - 23:00
Researchers from Penn's School of Veterinary Medicine have landed on encouraging findings to take on Strongyloides stercoralis, a parasitic nematode that's infected millions of people around the world.

First-of-its-kind chemical oscillator offers new level of molecular control

Mié, 12/13/2017 - 23:00
UT researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.

NSF-funded researchers find that ice sheet is dynamic and has repeatedly grown and shrunk

Mié, 12/13/2017 - 23:00
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink.

Suicidal thoughts rapidly reduced with ketamine, finds study

Mié, 12/13/2017 - 23:00
Ketamine was significantly more effective than a commonly used sedative in reducing suicidal thoughts in depressed patients, according to researchers at Columbia University Medical Center (CUMC). They also found that ketamine's anti-suicidal effects occurred within hours after its administration.

Six-decade-old space mystery solved with shoebox-sized satellite called a CubeSat

Mié, 12/13/2017 - 23:00
A 60-year-old mystery about the source of energetic, potentially damaging particles in Earth's radiation belts has been solved using data from a shoebox-sized satellite built and operated by students. The satellite is called a CubeSat.

A better way to weigh millions of solitary stars

Mié, 12/13/2017 - 23:00
Astronomers have come up with a new and improved method for measuring the masses of millions of solitary stars, especially those with planetary systems.

Simulation model finds Cure Violence program and targeted policing curb urban violence

Mié, 12/13/2017 - 23:00
When communities and police work together to deter urban violence, they can achieve better outcomes with fewer resources than when each works in isolation, a simulation model created by researchers at the UC Davis Violence Prevention Research Program, Columbia University's Mailman School of Public Health and the University at Albany has found.

Computational strategies overcome obstacles in peptide therapeutics development

Mié, 12/13/2017 - 23:00
Recently developed computational strategies could help realize the promise of peptide-based drugs. Researchers were able to sample the diverse landscape of shapes that peptides can form as a guide for designing the next generation of stable, potent, selective drugs. They compiled a library of peptide scaffolds upon which drug candidates might be designed. Their methods also can be used to design additional custom peptides with arbitrary shapes on demand.

ESMO, the leading professional organization for medical oncology, published a position paper on supportive and palliative care in its leading scientific journal, Annals of Oncology today.

Regular takeaways linked to kids' heart disease and diabetes risk factors

Mié, 12/13/2017 - 23:00
Kids who regularly eat takeaway meals may be boosting their risk factors for heart disease and diabetes, suggests research published online in the Archives of Disease in Childhood.

Despite removal of many obstacles, UK child organ donation rates remain low

Mié, 12/13/2017 - 23:00
Despite the removal of many logistical/professional obstacles, and clear guidance from national bodies, UK child organ donation rates remain lower than in other comparable countries, say experts in a leading article published online in the Archives of Disease in Childhood.

Drinking hot tea every day linked to lower glaucoma risk

Mié, 12/13/2017 - 23:00
Drinking a cup of hot tea at least once a day may be linked to a significantly lower risk of developing the serious eye condition, glaucoma, finds a small study published online in the British Journal of Ophthalmology.

Horrific mating strategy appears to benefit both male and female redback spiders

Mié, 12/13/2017 - 23:00
A mating strategy among redback spiders where males seek out immature females appears to benefit both sexes, a new U of T Scarborough study has found.

Revealing the best-kept secrets of proteins

Mié, 12/13/2017 - 23:00
Salk scientists develop new approach to identify important undiscovered functions of proteins.

Hope for one of the world's rarest primates: First census of Zanzibar Red Colobus monkey

Mié, 12/13/2017 - 23:00
A team of WCS scientists recently completed the first-ever range-wide population census of the Zanzibar red colobus monkey (Piliocolobus kirkii) an endangered primate found only on the Zanzibar archipelago off the coast of East Africa.

Intervention offered in school readiness program boosts children's self-regulation skills

Mié, 12/13/2017 - 23:00
Adding a daily 20 to 30 minute self-regulation intervention to a kindergarten readiness program significantly boosted children's self-regulation and early academic skills, an Oregon State University researcher has found.

Mechanism identified of impaired dendritic cell function that weakens response to cancer

Mié, 12/13/2017 - 23:00
Wistar scientists revealed the mechanism implicated in the defective function of tumor-associated dendritic cells (DCs), a specialized type of immune cells that expose the antigens on their surface to activate the T cells.

Loose skin and 'slack volume' protect hagfish from shark bites

Mié, 12/13/2017 - 23:00
Chapman University has published new research showing how hagfishes survive an initial attack from predators before they release large volumes of slime to defend themselves. Because the slime is released after they are attacked, this defense strategy is only effective if they survive the initial bite. Results show that hagfish skin is not puncture resistant; it is both unattached and flaccid, which helps avoid internal damage from penetrating teeth.
