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 […]

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 […]

Vitamin D Could Reduce the Risk of Type 1 Diabetes

Vitamin D Could Halve the Risk of Type1 Diabetes

A new study from scientists at the Harvard School of Public Health suggests that vitamin D could protect against type 1 diabetes. Adequate levels of vitamin D during young adulthood may reduce the risk of adult-onset type 1 diabetes by as much as 50 percent, according to researchers at the Harvard School of Public Health […]

Triangular Layers of Tungsten Disulfide May Have Applications in Optical Technology

Light Emitting Triangles

Researchers at Penn State have created triangular single layers of tungsten disulfide that exhibit unusual photoluminescent properties and may have potential applications in optical technology. For the first time, scientists have created single layers of a naturally occurring rare mineral called tungstenite, or WS2. The resulting sheet of stacked sulfur and tungsten atoms forms a […]

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 […]

Unique Features of Spiral Galaxy Messier 106

Spiral Galaxy M 106

Located about 20 million light-years away, spiral galaxy M 106 has several unique features: instead of two spiral arms, it appears to have four and as gas spirals towards the black hole at its center, it heats up and emits powerful, bright microwave radiation. The NASA/ESA Hubble Space Telescope – with a little help from […]
