Researchers use Hubble Telescope to reveal cloudy weather on alien world
Weather forecasters on exoplanet GJ 1214b would have an easy job. Today's forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds. That's the implication of a study led by researchers in the Department of Astronomy and Astrophysics at the University of Chicago who have definitively characterized the atmosphere of a super-Earth class planet orbiting another star for the first time.

Malaria drug target raises hopes for new treatments
Malaria drug target raises hopes for new treatments
Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying. In a study published in Nature Chemistry , they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from showing symptoms and extends their lifespan.

Electron's shapeliness throws a curve at supersymmetry
A small band of particle-seeking scientists at Yale and Harvard has established a new benchmark for the electron's almost perfect roundness, raising doubts about certain theories that predict what lies beyond physics' reigning model of fundamental forces and particles, the Standard Model.

Roots of the Lithium Battery Problem: Berkeley Lab Researchers Find Dendrites Start Below the Surface
The lithium-ion batteries that power our laptops, smartphones and electric vehicles could have significantly higher energy density if their graphite anodes were to be replaced by lithium metal anodes. Hampering this change, however, has been the so-called dendrite problem. Over the course of several battery charge/discharge cycles, particularly when the battery is cycled at a fast rate, microscopic fibers of lithium, called "dendrites," sprout from the surface of the lithium electrode and spread like kudzu across the electrolyte until they reach the other electrode.

Drug residues in Swedish sewage water
Chemists at Umeň University have been able to trace narcotics substances and prescription drugs in measurements of wastewater from 33 Swedish sewage treatment plants. Cocaine, amphetamine, and methamphetamine, in measurable concentrations, were found in a total of half of the locations. When a person consumes a drug it is excreted through the digestive system, either unchanged or as metabolites through the body and ends up in the wastewater.

New recipe for novel proteins
New recipe for novel proteins
Yale researchers have discovered a targeted way to make proteins not generally found in nature by expanding the information encrypted in the genetic code. Working with bacteria, the Yale team rewrote most of the genetic instructions that encode all 20 amino acids - the building blocks of any protein - to create a specific, 21 st amino acid, researchers report in the January 2014 issue of the journal Angewandte Chemie.

A new step towards graphene-based electronics
A new step towards graphene-based electronics
13 Dec 2013 University of Manchester scientists have helped demonstrate that long, structurally well-defined ribbons of graphene can be made. Writing , researchers used different characterisation techniques, including Raman spectroscopy – led by Dr Cinzia Casiraghi and her group – to confirm that these ribbons, called GNRs, are structurally well-defined and have excellent charge-carrier mobility.

Noble gas molecule discovered in space
A molecule containing a noble gas has been discovered in space by a team including astronomers from Cardiff University. The find was made using a Cardiff-led instrument aboard Europe's Herschel Space Observatory. The molecule, argon hydride, was seen in the Crab Nebula, the remains of a star that exploded 1,000 years ago.

$4M gift will propel quantum materials studies
A revolutionary instrument that will expedite the discovery of new, artificial forms of matter with unprecedented electronic and magnetic properties will be funded by a $4.13 million gift from the Gordon and Betty Moore Foundation. The new instrument, to be called the Moore CONQUEST (Creation and Observation of Novel Quantum Electronic Structures) facility, will integrate three separate pieces of cutting-edge technology for synthesizing and studying such materials.

Remembrances of Things Past: Berkeley Lab Researchers Discover Nanoscale Shape-Memory Oxide
Remembrances of Things Past: Berkeley Lab Researchers Discover Nanoscale Shape-Memory Oxide
Listen up nickel-titanium and all you other shape-memory alloys, there's a new kid on the block that just claimed the championship for elasticity and is primed to take over the shape memory apps market at the nanoscale. A research team at Berkeley Lab has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14-percent on the nanoscale, larger than any shape-memory effect observed in a metal.

Detailed image shows how genomes are copied
For the first time, researchers at Umeň University have succeeded in showing how the DNA polymerase epsilon enzyme builds new genomes. The detailed image produced by these researchers shows how mutations that can contribute to the development of colorectal cancer and cervical cancer lead to changes in the structure of the protein.

Lugworms find microplastic pollution not to their tastes
Tiny bits of plastic trash could spell big trouble for some of the smallest and most crucial members of the marine ecosystem according to scientific findings released today. Research conducted by Plymouth University and the University of Exeter has revealed the unpalatable situation confronting the lugworm when it is exposed to high levels of microplastic in ocean sediments.

Nobel laureate marks Bragg centenary
Professor Dan Shechtman celebrated crystallography's profound impact on modern science in the Bragg Centenary Lecture 2013 - and explained how he overturned one of the discipline's key principles. Professor Shechtman, winner of the Nobel Prize in Chemistry in 2011, spoke in the University’s Rupert Beckett Lecture Theatre on November 21 at the culmination of a year of events marking the centenary of the development of X-ray crystallography by William Henry Bragg and William Lawrence Bragg at Leeds in 1912-13.

An Inside Look at a MOF in Action
An Inside Look at a MOF in Action
A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first in situ electronic structure observations of the adsorption of carbon dioxide inside Mg-MOF-74, an open metal site MOF that has emerged as one of the most promising strategies for capturing and storing greenhouse gases.

Additive may make wine fine for a longer time
UNIVERSITY PARK, Pa. An additive may help curb a chemical reaction that causes wine to look, smell and taste funky, according to food scientists. The researchers added chelation compounds that bind with metals to inhibit oxidation, or oxygen's ability to react with some of the trace metals that are found in the wine, according to Gal Kreitman , a doctoral candidate in food science , Penn State.

Study could lead to paradigm shift in organic solar cell research
A new study by Stanford scientists overturns a widely held explanation for how organic photovoltaics turn sunlight into electricity. Organic solar cells have long been touted as lightweight, low-cost alternatives to rigid solar panels made of silicon. Dramatic improvements in the efficiency of organic photovoltaics have been made in recent years, yet the fundamental question of how these devices convert sunlight into electricity is still hotly debated.

Amber Provides New Insights Into the Earth’s Atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earth's geological past than previously assumed.
