New role of cholesterol in regulating brain proteins discovered

Science Daily - Thu, 23/02/2017 - 4:48pm
A study demonstrates that the cholesterol present in cell membranes can interfere with the function of an important brain membrane protein, through a previously unknown mode of interaction. Specifically, cholesterol is capable of regulating the activity of the adenosine receptor, by invading it and accessing the active site. This will allow new ways of interacting with these proteins to be devised that in the future could lead to drugs for treating diseases like Alzheimer's.

Removing barriers to early intervention for autistic children: A new model shows promise

Science Daily - Thu, 23/02/2017 - 4:48pm
Acting on recommendations from the South Carolina Act Early Team, South Carolina changed its policies to pay for early intensive behavioral intervention in children under three revealed to be at high risk for autism spectrum disorder (ASD) by a two-stage screening process. Previously, a formal diagnosis of ASD had been required. As a result, the number of children under three receiving early intervention grew five-fold.

Tumor protein could hold key to pancreatic cancer survival

Science Daily - Thu, 23/02/2017 - 4:48pm
A diagnosis of pancreatic cancer is often a death sentence because current chemotherapies have little impact on the disease. In a new study, researchers were able to slow down growth and spread of tumors by targeting this protein in stellate cells in animal models, in combination with current chemotherapies.

Sons of cocaine-using fathers have profound memory impairments

Science Daily - Thu, 23/02/2017 - 4:48pm
Fathers who use cocaine at the time of conceiving a child may be putting their sons at risk of learning disabilities and memory loss. The researchers say the findings reveal that drug abuse by fathers -- separate from the well-established effects of cocaine use in mothers -- may negatively impact cognitive development in their male offspring.

Trilobite eggs in New York

Science Daily - Thu, 23/02/2017 - 4:47pm
Despite a plethora of exceptionally preserved trilobites, trilobite reproduction has remained a mystery. No previously described trilobite has had unambiguous eggs or genitalia preserved. A new study reports the first occurrence of in situ preserved trilobite eggs from the Lorraine Group in upstate New York, USA.

Researchers use laser-generated bubbles to create 3-D images in liquid

Science Daily - Thu, 23/02/2017 - 4:47pm
Researchers have developed a completely new type of display that creates 3-D images by using a laser to form tiny bubbles inside a liquid 'screen.' Instead of rendering a 3-D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric. This allows viewers to see a 3-D image in the columnar display from all angles without any 3-D glasses or headsets.
