Thermal-Imaging Quickly Tracks Energy Leaks in Homes and Buildings

Thermal-Imaging Cars Can Quickly Track Energy Leaks

New thermal-imaging cars from MIT spinout Essess can quickly track energy leaks in thousands of homes and buildings, helping owners curb energy loss. In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now MIT spinout Essess is bringing similar “drive-by” innovations to energy efficiency […]

New Research Identifies Enzyme Crucial to the Shaping and Division of Brain Cells

Study Identifies Enzyme Crucial to the Shaping and Division of Brain Cells

A newly published study identifies a “cutting” enzyme crucial to the shaping and division of brain cells as well as the replenishment of neural stem cells. The study, appearing online December 17 in the journal Neuron, helps explain the molecular basis of complex brain abnormalities, including small brain size (microcephaly) observed in children who were […]

Hubble Image of R Sculptoris and Its Hidden Companion

Hubble Image of the Day R Sculptoris

This newly released Hubble images shows star R Sculptoris, a red giant located 1,500 light-years from Earth in the constellation of Sculptor. Recent observations have shown that the material surrounding R Sculptoris actually forms a spiral structure — a phenomenon probably caused by a hidden companion star orbiting the star. Systems with multiple stars often […]

Signal Molecule Gives Rise to New Blood Stem Cells in Embryos

Molecule Gives Rise to New Blood Stem Cells in Embryos

A newly published study from the Max Planck Institute details how interferon gamma plays a key role in the development of blood stem cells during the early phase of embryonic development. In the early stage of embryonic development, stem cells with defined tasks, including blood-forming stem cells, gradually emerge. Scientists from the Max Planck Institute […]

A New Set of Calculations for Catastrophic Disruptions of Main Belt Asteroids

Catastrophic Disruption Rate of Small Main Belt Asteroids

A team of astronomers has revealed a new set of calculations for catastrophic disruptions of main belt asteroids, finding that for asteroids about one hundred meters in diameter collisions are not the primarily cause of break ups – rapid rotation is. Hundreds of thousands of asteroids are known to orbit our Sun at distances ranging […]

Scientists Shed New Light on How ‘Microbial Dark Matter’ Might Cause Disease

How Microbial Dark Matter Might Cause Disease

A landmark discovery reveals new insights on the biological, ecological and medical importance of TM7, and could lead to better understanding of other elusive bacteria. One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still […]

Study Shows Digital Books Can Adversely Impact Overall Health

E-Readers Foil Good Night’s Sleep

A newly published study from Harvard Medical School reveals that using light-emitting electronic devices before bedtime can adversely impact overall health. Use of a light-emitting electronic book (LE-eBook) in the hours before bedtime can adversely impact overall health, alertness and the circadian clock, which synchronizes the daily rhythm of sleep to external environmental time cues, […]

The Role of Genetics Varies Over Time

Nature and Nurture Vary Over Time

New research from Yale University shows that the effect of genes may depend on the total, historical environment in which the researcher and subject are embedded. Nature and nurture have found a new companion — historical context. A new study has produced the best evidence yet that the role of genetics in complex traits, including […]

Tropical Forests May Be Absorbing More Carbon Dioxide Than Previously Thought

Study Shows Tropical Forests Absorbing More Carbon Dioxide

A newly published study from NASA scientists shows that tropical forests, like the one pictured above, absorb more atmospheric carbon dioxide than boreal forests. A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study […]

Floating Nuclear Power Plants Could Enhance Safety

Floating Nuclear Plants Could Enhance Safety

MIT researchers detail how a floating nuclear power plant design could provide enhanced safety – it would be unaffected by the motions of a tsunami and earthquakes would have no direct effect at all. Floating nuclear plants could withstand earthquakes and tsunamis. Video: Christopher Sherrill, courtesy of the Department of Nuclear Science and Engineering When […]

Yale Study Shows Metformin May be Safe for Patients with Kidney Disease

Diabetes Drug May be Safe for Patients with Kidney Disease

A newly published study from Yale University reveals that metformin (the most popular treatment for type 2 diabetes) may be safer for patients with mild to moderate kidney disease than guidelines suggest. The new study is published by Yale investigators in the Journal of the American Medical Association (JAMA). For 20 years, metformin has been […]
