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 […]

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 […]

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 […]

Mysterious Infant Star Unleashes Strobe-Like Flashes of Light

Flashes in a Suspected Binary Protostar

A newly published study details a mysterious infant star, designated LRLL 54361, that unleashes strobe-like flashes of light every 25.34 days. Two of NASA’s great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light. Every 25.34 days, the object, designated LRLL 54361, […]

Researchers Develop a Self-Charging Power Cell

A Self Charging Power Cell

Engineers at the Georgia Institute of Technology have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, a new hybrid generator-storage cell utilizes mechanical energy more […]

Earth-like Planets May Have Older and More Evolved Life

Habitable Planet With Two Moons Orbiting a Red Dwarf Star

Astronomers at the Harvard-Smithsonian Center for Astrophysics believe that six percent of red dwarf stars have habitable, Earth-sized planets. Since red dwarfs live much longer than Sun-like stars, this discovery raises the possibility that some of these planets may have much older and more evolved life than on Earth. Cambridge, Massachusetts – Using publicly available […]
