Scientists Reconstruct the Ancestor of Placental Mammals

Ancestor of Placental Mammals

More than twenty scientists collaborated on a recently published study that reconstructed the ancestor of placental mammals. The common ancestor of more than 5,000 contemporary placental mammals such as rats, whales, and humans was a small, insect-eating animal that appeared after the dinosaurs went extinct 65 million years ago, an international team of researchers report […]

Layered Oxide Heterostructures Produce Efficient Solar Cells

Layered Oxide Heterostructures Create Efficient Ultra Thin Solar Cells

In a newly published study, an international team of scientists have shown that layered oxide heterostructures can be used to create a new kind of extremely efficient ultra-thin solar cells. Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted […]

Natural Toxins Combined with Synthetic Drugs Could Disarm Cancer, Drug-Resistant Bacteria

Natural Toxins Could Disarm Cancer and Drug Resistant Bacteria

Researchers at Rice University believe that combining natural toxins with man-made mirror drugs will create the drug equivalent of a one-two punch, “confusing” bacteria and cancer and preventing them from rapidly becoming resistant to the man-made drugs. Cancer researchers from Rice University suggest that a new man-made drug that’s already proven effective at killing cancer […]

Researchers Identify a Protein that Blocks HIV

25HC Suppresses HIV Growth

In a newly published study, scientists have shown that an oxysterol called 25-hydroxycholesterol (25HC) suppresses HIV growth in vivo. A team of UCLA-led researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others […]

Copper Sulfide Could Enable Faster Memory Chips and More Efficient Batteries

Cooper Sulfide Could Enable Faster Memory Chips

A new study from SLAC and Stanford researchers examines the atomic-scale details of how superionic nanoscale materials switch from a state that is poorly conducting to one that is highly conducting, taking a step forward toward using these materials in low-cost solid-state electrical batteries. A material that could enable faster memory chips and more efficient […]

Curiosity Drills and Collects First Martian Bedrock Sample

Curiosity Collects First Martian Bedrock Sample

New images show that NASA’s Curiosity rover has successfully drilled and collected a rock powder sample from the Martian bedrock to be analyzed. Pasadena, California — NASA’s Curiosity rover has, for the first time, used a drill carried at the end of its robotic arm to bore into a flat, veiny rock on Mars and […]

Synthetic Biology Circuits Perform Logic Functions and Remember the Results

Synthetic Biology Circuits

Researchers at MIT have developed new synthetic biology circuits that combine memory and logic. MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell’s DNA and passed on for dozens of generations. The circuits, described in the Feb. 10 […]

Asthma Drug May Lead to New Treatments for Diabetes and Obesity

New Treatments for Diabetes and Obesity

A newly published study from the University of Michigan found that a currently available asthma drug reverses obesity, diabetes and fatty liver in mice. Ann Arbor — Researchers at the University of Michigan’s Life Sciences Institute have found that amlexanox, an off-patent drug currently prescribed for the treatment of asthma and other uses, also reverses […]

Direct Infrared Image of the Protoplanetary Disk around a Young Star

Image of the Protoplanetary Disk Around the Young Star J 1604

Using the high-resolution infrared camera HiCIAO, an international group of astronomers captured the first vivid infrared image of a curved arm of dust extending over a hole on a disk around a young star, 2MASS J16042165-2130284 (J 1604). An international team of astronomers led by Satoshi Mayama (The Graduate University for Advanced Studies, Japan) and […]

Hubble Views Spiral Galaxy ESO 121-6

Galaxy ESO 121 6

This Hubble Space Telescope image shows spiral galaxy ESO 121-6 and numerous nearby stars and galaxies. This thin, glittering streak of stars is the spiral galaxy ESO 121-6, which lies in the southern constellation of Pictor (The Painter’s Easel). Viewed almost exactly side-on, the intricate structure of the swirling arms is hidden, but the full […]

Nanocapsules Battle Cancer without Harming Healthy Cells

Nanocapsules Effectively Kill Cancer Cells

Scientists at UCLA have developed nanocapsules that battle cancer cells without harming healthy cells, providing researchers with a potentially a new way to treat cancer. A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment. Devising a method for more precise and less invasive treatment of cancer tumors, […]
