Successful First Observations of Galactic Center with GRAVITY

118184_web.jpg

The GRAVITY instrument is now operating with the four 8.2-metre Unit Telescopes of ESO's Very Large Telescope (VLT - http://www.eso.org/public/teles-instr/paranal/) , and even from early test results it is already clear that it will soon be producing world-class science.

Columbia Engineers Develop New, Low-Cost Way to Capture Carbon

Chen-Energylevelsofionhydrationwithdifferentwateramounts.jpg

Xi Chen, associate professor of earth + environmental engineering at Columbia Engineering, and Klaus Lackner at Arizona State University, reports an unconventional reversible chemical reaction in a confined nanoenvironment. The discovery, a milestone in clarifying the scientific underpinnings of moisture-swing chemical reaction, is critical to understanding how to scrub CO2 from the Earth's atmosphere; the researchers have already used it to capture CO2 more efficiently and at a much lower cost than other methods.

Learning About the Future From the Distant Past

Our universe came to life nearly 14 billion years ago in the Big Bang — a tremendously energetic fireball from which the cosmos has been expanding ever since. Today, space is filled with hundreds of billions of galaxies, including our solar system's own galactic home, the Milky Way. But how exactly did the infant universe develop into its current state, and what does it tell us about our future?

Dormant Black Hole Eats Star, Becomes X-Ray Flashlight

118069_web.jpg

Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But sometimes a star wanders too close to a dormant black hole and the ensuing feeding frenzy, known as a tidal disruption event, sets off spectacular fireworks.

Australia 20 Years After Gun Reform -- No Mass Shootings, Declining Firearm Deaths

Since gun law reform and the Firearms Buyback program 20 years ago, Australia has seen an accelerating decline in intentional firearm deaths and an absence of fatal mass shootings, the Journal of the American Medical Association (JAMA) reports today in a landmark study.

Many West Nile encephalitis survivors suffer long-term neurological problems such as memory loss. New research from Washington University School of Medicine shows that the patients’ own immune systems may have destroyed parts of their neurons, and that intervening in the immune response may help.

In a five-year study on primary school children in Singapore, researchers from the National University of Singapore found that children with intrusive parents had a higher tendency to be overly critical of themselves, and this tendency increased over the years.

'Space Tsunami' Causes the Third Van Allen Belt

118011_web.jpg

Earth's magnetosphere, the region of space dominated by Earth's magnetic field, protects our planet from the harsh battering of the solar wind. Like a protective shield, the magnetosphere absorbs and deflects plasma from the solar wind which originates from the Sun. When conditions are right, beautiful dancing auroral displays are generated. But when the solar wind is most violent, extreme space weather storms can create intense radiation in the Van Allen belts and drive electrical currents which can damage terrestrial electrical power grids. Earth could then be at risk for up to trillions of dollars of damage.

Predicting Loaf Volume Without Baking the Bread

Scoringbread_1.jpg

When it comes to baking bread, the bigger the loaf, the better. But to determine the baking performance of wheat flour, food scientists had to bake a loaf of bread. That may not be necessary, thanks to a new mathematical model that uses specific dough parameters to predict loaf volume. That saves time and money.

Rapid Medicaid Expansion in Michigan Didn’t Reduce Access to Primary Care

Despite predictions that expanding Medicaid would crowd doctor’s offices with new patients, and crowd out patients with other kinds of insurance, a new University of Michigan study finds no evidence of that effect.
