Slinn Pickings latest 10

  • Reprogrammed stem cells hit a roadblock – An international study shows that reprogramming cells leads to genomic aberrations.
  • Blocking enzyme cut cancer spread – Scientists at the UK's Institute of Cancer Research have prevented breast cancer spreading to other organs in mice by blocking a chemical. In their experiments, they showed that blocking the enzyme LOXL2 prevented metastasis.
  • Warring molecules keep the colon cancer-free – KU associate professor of molecular biosciences Kristi Neufeld and her graduate student Erick Spears study how a molecule, a protein called APC, suppresses colon cancer. In a recent article in the Journal of Biological Chemistry, they explain how a drug might someday treat the disease by blocking the action of one of APC’s molecular opponents.
  • Nanolasers grown on silicon allow bottom-up nano-optoelectronic integration – Researchers at UC Berkeley have developed a way to grow III-V nanolasers on silicon, demonstrating the potency of bottom-up nano-optoelectronic integration.
  • Microbially produced ferrous iron may decrease technetium concentrations in groundwater – Microbially produced ferrous iron may decrease technetium concentrations in groundwater, it has been found.
  • Lithium-ion battery with new chemistry could power electric vehicles – Researchers have developed a novel type of lithium-ion battery with an anode and cathode that involve new, advanced battery chemistries, greatly improving the battery’s performance and likely making it suitable for electric vehicles.
  • Breathe, and a nanogenerator will power your pacemaker – Previous research has showed that high performance piezoelectric ceramics PZT (lead zirconate titanate) could be printed as nanoribbons onto biocompatible and flexible substrates for applications such as harvesting energy from human motion like walking or breathing ("Electricity-generating silicone implants could power electronic devices"). Researchers now report that they have succeeded in fabricating stretchable nanothick ribbons of piezoelectric PZT.
  • Nanotechnology-based solutions for oil spills – Conventional techniques are not adequate to solve the problem of massive oil spills. In recent years, nanotechnology has emerged as a potential source of novel solutions to many of the world's outstanding problems. Although the application of nanotechnology for oil spill cleanup is still in its nascent stage, it offers great promise for the future. In the last couple of years, there has been particularly growing interest worldwide in exploring ways of finding suitable solutions to clean up oil spills through use of nanomaterials.
  • Antifungal compound found on tropical seaweed has promising antimalarial properties – A group of chemical compounds used by a species of tropical seaweed to ward off fungus attacks may have promising antimalarial properties for humans. The compounds are part of a unique chemical signaling system that seaweeds use to battle enemies — and that may provide a wealth of potential new pharmaceutical compounds.
  • Brain imaging reveals pessimism as self-fulfilling prophecy – By manipulating your expectations, you can double or halve the potency of the drugs you take. Scientists show that a gloomy outlook towards medical treatment may decrease the effectiveness of the drugs – based on brain images of thoughts, feelings, and past experiences.
