Scientists have focused on certain p53 mutations that generate mutant proteins that promote cancer growth and metastasis. The variants studied are truncated -- they lack half of the domains, or units, of the full-length p53 protein, which enable full-length p53 to enter the cell nucleus and bind DNA, essential in its normal tumor-suppressor function. The truncated mutants act by perturbing mitochondrial function, the team proposes.
Article describes latest research on magnetic reconnection.
Battery researchers have used a special electron microscope with atomic-level resolution to show that certain large ions can hold open tunnels in a promising electrode material, so that charge-carrying ions like lithium can enter and exit the electrode easily and quickly -- boosting capacity.
After decades of eluding researchers because of chemical instability, key metal-oxide clusters have been isolated in water, a significant advance for growing the clusters with the impeccable control over atoms that's required to manufacture small features in electronic circuits.
A severely brain injured woman, who recovered the ability to communicate using her left eye, restored connections and function of the areas of her brain responsible for producing expressive language and responding to human speech, according to new research from Weill Cornell Medicine scientists.
An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits. An important prerequisite for the realization of high-performance quantum computers is that the stored data should remain intact for as long as possible. The researchers, including Jülich physicist Dr. Gianluigi Catelani, have developed and tested a technique that removes unpaired electrons from the circuits. These are known to shorten the qubit lifetime.
Just because temperatures are cooling down as winter approaches, it's no time to let your guard down when it comes to mosquitoes that can carry the Zika virus. LSU Health New Orleans' Dr. James Diaz details characteristics of the mosquitoes capable of transmitting the Zika virus in the United States, their habitats and biting behaviors, as well as control measures, in a paper published in the December 2016, issue of Wilderness & Environmental Medicine.
Tiny predators in the soil can literally sniff out their prey: soil bacteria, which communicate with each other using scent. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) has discovered that these predators -- called protists - 'eavesdrop' on the bacteria's communication. It's a discovery that opens up perspectives for agriculture. The results are available online this month in The ISME Journal, from the publishers of Nature.
Pushing nanoscale battery developments in the right direction can help create a sustainable transport sector.
A research team led by Jefferson Lab's Robert Edwards has been using computation to inform GlueX experiments at Jefferson Lab as well as corroborate experimental findings.
