This method is a step forward in the study of protein dynamics, of great importance for the design of drugs and the investigation of genetic diseases such as cancer.

Halloysite: Finally a promising natural nanomaterial? Posted: 23 Oct 2015 09:18 AM PDT Halloysite is a natural biocompatible nanomaterial available in thousands of tons at low price, which makes it a good candidate for nanoarchitectural composites. In vitro and in vivo studies on biological cells and worms indicate the safety of halloysite, and furthermore, it can store and release molecules in a controllable manner, making these tiny containers attractive for applications in drug delivery, antimicrobial materials, self-healing polymeric composites, and regenerative medicine.

Scientists urge policymakers to plant more trees to save Britain's rivers from climate change Posted: 23 Oct 2015 07:58 AM PDT New research has prompted scientists to call on policymakers to plant more trees alongside upland rivers and streams, in an effort to save their habitats from the future harm of climate change.

Questioning simple groundwater models on the Liverpool Plains, NSW, Australia Posted: 23 Oct 2015 05:45 AM PDT Millions of years go missing: New research identifies a gap in sediments and questions simple groundwater models on the Liverpool Plains, NSW, Australia.

Alzheimer risk impairs 'satnav' function of the brain Posted: 23 Oct 2015 05:45 AM PDT Young adults with genetically increased Alzheimer's risk have altered activation patterns in a brain region that is crucial for spatial navigation.

Optical scanner shows potential for real-time 3-D breast cancer screening Posted: 23 Oct 2015 05:41 AM PDT Scientists have developed a hand-held optical scanner with the potential to offer breast cancer imaging in real time. The device uses a near-infrared laser diode source to produce an image of the breast tissues.

Manipulating wrinkles could lead to graphene semiconductors Posted: 23 Oct 2015 05:41 AM PDT Scientists have used the tip of a scanning tunneling microscope to manipulate the formation of wrinkles in graphene, opening the way to the construction of graphene semiconductors not through chemical means--by adding other elements -- but by manipulating the carbon structure itself in a form of 'graphene engineering.'

Lack of adequate food is ongoing health risk to US children Posted: 23 Oct 2015 05:37 AM PDT For the first time, the American Academy of Pediatrics (AAP) is recommending that pediatricians screen all children for food insecurity. In a new policy statement identifying the short and long-term adverse health impacts of food insecurity, the AAP also recommends that pediatricians become familiar with and refer families to needed community resources, and advocate for federal and local policies that support access to adequate, nutritious food.

Iinjuries from nonpowder guns severe among children Posted: 23 Oct 2015 05:37 AM PDT Researchers have shown that nonpowder firearms such as airsoft, BB, and paintball guns should not be viewed as toys, but rather powerful weapons causing increasingly severe and sometimes life-threatening injuries in pediatric patients.

A longer look at treatments for leg length discrepancies Posted: 23 Oct 2015 05:37 AM PDT When balancing treatment options for a child with a significant difference in leg length, doctors typically advise families about the risks and benefits of surgeries to either shorten or elongate one of the limbs. New research suggests they may also want to consider how the child's ultimate height will affect his or her income as an adult.
