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

EurekAlert! - 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

EurekAlert! - 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 publishes new position paper on supportive and palliative care

EurekAlert! - Mié, 12/13/2017 - 23:00
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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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.

New antbird species discovered in Peru by LSU ornithologists

EurekAlert! - Mié, 12/13/2017 - 23:00
LSU describes a distinctive new species of antbird from humid montane forest of the Cordillera Azul, Martin Region, Peru.

Computer systems predict objects' responses to physical forces

EurekAlert! - Mié, 12/13/2017 - 23:00
Presenting their work at this year's Conference on Neural Information Processing Systems, Prof. Josh Tenenbaum and one of his students, Jiajun Wu, are co-authors on four papers that examine the fundamental cognitive abilities that an intelligent agent requires to navigate the world: discerning distinct objects and inferring how they respond to physical forces.

National MagLab's latest magnet snags world record, marks new era of scientific discovery

EurekAlert! - Mié, 12/13/2017 - 23:00
The Florida State University-headquartered National High Magnetic Field Laboratory has shattered another world record with the testing of a 32-tesla magnet -- 33 percent stronger than what had previously been the world's strongest superconducting magnet used for research and more than 3,000 times stronger than a small refrigerator magnet.

Northeast farmers weigh warming climate, drenched fields

EurekAlert! - Mié, 12/13/2017 - 23:00
Farmers in the Northeast are adapting to longer growing seasons and warming climate conditions -- but they may face spring-planting whiplash as they confront fields increasingly saturated with rain, according to a research paper published in the journal Climatic Change.

Single-stranded DNA and RNA origami go live

EurekAlert! - Mié, 12/13/2017 - 23:00
A novel approach published in Science by a collaborative team of researchers from the Wyss Institute, Arizona State University, and Autodesk for the first time enables the design of complex single-stranded DNA and RNA origami that can autonomously fold into diverse, stable, user-defined structures.
