• 17:24 Fool's gold may prove an unlikely alternative to overexploited catalytic materials

  Read the story at PhysOrg
  Catalytic materials, which lower the energy barriers for chemical reactions, are used in everything from the commercial production of chemicals to catalytic converters in car engines. However, with current catalytic materials becoming increasingly expensive, scientists are exploring viable alternatives.

• 17:24 News of plaque-clearing drug tops week of major advances against Alzheimer's disease

  Read the story at PhysOrg
  In the last eight days, scientists have delivered a powerful one-two punch in the fight to defeat Alzheimer's disease. At the same time, the White House and members of Congress are proposing increases in Alzheimer's research funding. This has been a big week for all who seek to end this disease, says the CEO of the American Health Assistance Foundation.

• 17:24 No entry without protein recycling: Researchers discover new coherence in enzyme transport

  Read the story at PhysOrg
  The group of Prof. Dr. Ralf Erdmann at the Ruhr-Universität Bochum, Germany, discovered a connection of peroxisomal protein import and receptor export. In the Journal of Biological Chemistry, they disclosed that enzymes only get imported into certain cell organelles (peroxisomes) upon coupling of their import to the recycling of their transport protein (receptor).

• 17:24 Team isolates nerve cells involved in storing long term memory and gene proteins associated with them

  Read the story at PhysOrg
  (Medical Xpress) -- A research team in Taiwan has succeeded in isolating two nerve cells in fruit fly brains that are believed to be the major players in allowing for the formation of long term memories. Furthermore, they’ve also found the genes that appear to be essential in creating related proteins that allow such memories to be saved. They have published a paper describing their work in Science.

• 17:24 The power of estrogen -- male snakes attract other males

  Read the story at PhysOrg
  A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood – attracting dozens of other males eager to mate.

• 17:24 To avoid early labor and delivery, weight and diet changes not the answer

  Read the story at PhysOrg
  One of the strongest known risk factors for spontaneous or unexpected preterm birth – any birth that occurs before the 37th week of pregnancy, most often without a known cause – is already having had one. For women in this group who would like to avoid this scenario in their second pregnancy, focusing on weight gain and dietary changes may not be the best strategy. A new study reported at the Society for Maternal-Fetal Medicine's annual meeting found no connection between weight gain and the risk of repeat preterm birth.

• 17:24 Unpicking HIV`s invisibility cloak

  Read the story at PhysOrg
  Drug researchers hunting for alternative ways to treat human immunodeficiency virus (HIV) infections may soon have a novel target—its camouflage coat. HIV hides inside a cloak unusually rich in a sugar called mannose, which it uses to slip past the immune system before infecting its host’s cells. Recently, however, biochemists discovered a family of chemical compounds that stick strongly to mannose. Understanding how this mechanism works could reveal a way to make drugs adhere to and kill HIV. Yu Nakagawa and Yukishige Ito at the RIKEN Advanced Science Institute in Wako and their colleagues from several research institutes in Japan are leading the effort: they have mapped the binding site of the mannose-binding compound pradimicin A.

• 17:24 What lies beneath: Mapping hidden nanostructures

  Read the story at PhysOrg
  The ability to diagnose and predict the properties of materials is vital, particularly in the expanding field of nanotechnology. Electron and atom-probe microscopy can categorize atoms in thin sheets of material, and in small areas of thicker samples, but it has proven far more difficult to map the constituents of nanostructures inside large, thick objects.  X-rays—the most common imaging tool for hard biological materials such as bones—have a limited focal-spot size, so they cannot focus on nanoscale objects.

• 15:24 A frank discussion of the power law and linking correlation to causation

  Read the story at PhysOrg
  (PhysOrg.com) -- Michael Stumpf a mathematics professor at Imperial College in London, and Mason Porter a lecturer at Oxford have teamed together to write and publish a perspective piece in Science regarding the inexact science of trying to apply the power law to situations in science where it’s not always easy to show a direct link between correlation and causation, a key problem they say, in much of the science that is conducted today.

• 15:24 Cure of ADPKD by selection for spontaneous genetic repair events in Pkd1-mutated iPS cells

  Read the story at PhysOrg
  A research group including Kyoto University researchers demonstrates that mouse iPS cells, in which genetic correction occurs spontaneously through mitotic recombination, is selectable from the population of genetically mutated iPS cells in the mouse model of autosomal dominant polycystic kidney disease (ADPKD). This technology could be applicable of genome editing in human iPS cells for curing patients with genetic disorders.
