Iron-Based HTS Shows Unexpected Electronic Asymmetry

Iron-based high-temp superconductors show unexpected electronic asymmetry

A new study from a team of physicists offers new clues to scientists studying the mystery of high-temperature superconductivity, finding that electronic properties of a new iron-based high-temperature superconductor were different in the horizontal and vertical directions. Physicists from Rice University, Kyoto University and the Japan Synchrotron Radiation Research Institute (JASRI) are offering new details […]

“Closed-Edge Graphene Nanoribbons”

closed-edge graphene nanoribbons

A newly published paper from Rice University researchers details facts and figures about “closed-edge graphene nanoribbons,” carbon nanotubes that appear to collapse during the growth process and have properties of both nanotubes and graphene nanoribbons. Researchers at Rice’s Richard E. Smalley Institute for Nanoscale Science and Technology have come up with a set of facts […]

Rediscovery Sheds New Light on the Behavior of the Proboscis Anole

new light on the behavior of the proboscis anole

A team of scientists, encouraged by a handful of sightings, traveled to Mindo looking for a lizard once thought to be close to extinction – the proboscis anole. There they rediscovered the species, suggesting the lizard isn’t as elusive as initially believed. As biological mysteries go, they don’t come much better than the proboscis anole. […]

Selenium Nanoparticles Reduce Staph Bacteria

coating of selenium nanoparticles significantly reduces the growth of Staphylococcus aureus on polycarbonate

By using selenium nanoparticles to coat polycarbonate, Brown University scientists were able to reduce the cultured populations of Staphylococcus aureus bacteria by as much as 90 percent on medical devices. Providence, Rhode Island (Brown University) — Selenium is an inexpensive element that naturally belongs in the body. It is also known to combat bacteria. Still, […]

All-Carbon Photovoltaic Cell to Harness Infrared Light

All-carbon solar cell

Using carbon nanotubes and C60, scientists at MIT developed the first all-carbon photovoltaic cell, a new kind of solar cell that could tap into solar energy reaching Earth’s surface in the near-infrared region of the spectrum. About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — […]

Data Suggests the Possible Presence of Ice at Shackleton Crater

Shackleton crater

Using a laser altimeter on the Lunar Reconnaissance Orbiter spacecraft, a team of scientists have mapped Shackleton crater with unprecedented detail, finding possible evidence for small amounts of ice on the crater’s floor. If humans are ever to inhabit the moon, the lunar poles may well be the location of choice: Because of the small […]

National Renewable Energy Laboratory Energy Analysis

Power Flow in 2050

A new report from the National Renewable Energy Laboratory suggests that renewable electricity generation from today’s technologies, in combination with a more flexible electric system, is more than adequate to supply 80% of total U.S. electricity generation in 2050. A report published by the National Renewable Energy Laboratory (NREL), the Renewable Electricity Futures Study (RE […]

Preserved Frogs May Hold Past Clues about Batrachochytrium Dendrobatidis

frogs hold clues to deadly pathogen

Using a molecular test called quantitative polymerase chain reaction, a new study examined 164 preserved amphibians for the presence of Batrachochytrium dendrobatidis, finding Bd in specimens dating back to the 1960s. A Yale graduate student has developed a novel means for charting the history of a pathogen deadly to amphibians worldwide. Katy Richards-Hrdlicka, a doctoral […]

Carbon Sequestration Likely to Cause Intraplate Earthquakes

the world's first commercial carbon storage project

A recently published paper from Stanford scientists suggests that carbon sequestration is likely to create pressure build-up large enough cause intraplate earthquakes, breaking the reservoirs’ seals and releasing the stored CO2. Carbon capture and storage, or CCS, is a major component of the world’s greenhouse gas reduction strategy. Involving injecting and storing carbon dioxidein underground […]

LCLS Finding Gives a Better Understanding of Light-Matter Interaction

damage process in nanometer-sized clusters of atoms is slower than expected from previous studies of atoms and simple molecules

While conducting experiments with the LCLS’s Atomic Molecular Optical instrument, a team of SLAC physicists found that the damage process in nanometer-sized clusters of atoms is slower than expected and believe these results could help develop more sophisticated models for studies of matter in extreme conditions. Any nanometer-sized sample exposed to the intense X-ray pulses […]

Detailed Images of NGC 6357 from ESO’s Very Large Telescope

Wide-field view of the area of NGC 6357

New images from European Southern Observatory’s Very Large Telescope show detailed images of NGC 6357, which contains a cluster of high-mass stars whose inhabitants are among the brightest in our galaxy. Deep in the Milky Way in the constellation of Scorpius (The Scorpion) lies NGC 6357, a region of space where new stars are being […]

Pre-Existing Mutations Can Lead to Drug Resistance in HIV

more effective HIV treatments

A newly published study examined data from 26 clinical trials to better understand how drug resistant HIV mutations form and to help find more effective treatments. In a step that may lead to more-effective HIV treatments, Harvard scientists have found that, in a small number of HIV patients, pre-existing mutations in the virus can cause […]

p65 Protein and its Interaction with Telomerase RNA

p65 protein with piece of telomerase RNA

Using both X-ray crystallography and nuclear magnetic resonance spectroscopy, UCLA biochemists have examined the structure of p65 protein and its interaction with telomerase RNA. UCLA biochemists have mapped the structure of a key protein–RNA complex that is required for the assembly of telomerase, an enzyme important in both cancer and aging. The researchers found that […]

Japanese Scientists Use Pluripotent Cells to Create Functional Liver Tissue

stem-cells

Japanese scientists have been able to induce stem cells to create liver-like tissue in a dish. The new findings were reported online by the journal Nature, but the scientists have yet to publish their findings. Once the achievement is accomplished, there could be several big clinical implications. This could mean that it would be possible […]
