Satellite-Based Assessment of Ocean Acidification

Ocean Acidification

Using satellite measurements, researchers a team of international collaborators are developing new methods to quantify ocean acidity around the globe. With fundamental changes happening to the chemistry of the world’s oceans, salinity information from ESA’s SMOS mission is being used with other Earth observation data to obtain information on ‘the other carbon dioxide problem’ – […]

Isotopic Evidence Shows Life Could Have Flourished on Earth 3.2 Billion Years Ago

Life Could Have Flourished on Earth 3.2 Billion Years Ago

New research from the University of Washington found evidence that life was pulling nitrogen out of the air and converting it into a form that could support larger communities 3.2 billion years ago. A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But […]

Stress Slows Women’s Recovery from Acute Myocardial Infarction

Stress Linked to Worse Recovery in Women after Heart Attack

A new study from Yale University shows that stress plays a role in the sex-based differences in recovery after acute myocardial infarction. Young and middle-aged women experience more stress than their male counterparts, which could contribute to worse recovery from acute myocardial infarction (AMI), according to new findings by Yale School of Medicine researchers and […]

Scientists Find Link in How Cells Start Process Necessary for Life

Researchers Find Link in How Cells Start Process Necessary for Life

While exploring whether a structured RNA molecule from a virus that infects eukaryotic cells could function in bacteria, scientists found that it could initiate protein syntheses – a process necessary for life. Aurora, Colorado – Researchers have found an RNA structure-based signal that spans billions of years of evolutionary divergence between different types of cells, […]

CfA Astronomers Examine the Dynamics of Collapsing Cores and Star Formation

Study Reveals  Dynamics of Collapsing Cores and Star Formation

New research from the Harvard-Smithsonian Center for Astrophysics measures the velocity distribution of the gas in a pre-stellar core, revealing the dynamics of collapsing cores and star formation. Stars like the Sun begin their lives as cold, dense cores of dust and gas that gradually collapse under the influence of gravity until nuclear fusion is […]

Hubble Views Globular Cluster Palomar 12

Hubble Views Globular Cluster of Stars Palomar 12

This newly released Hubble image shows a globular cluster of stars known as Palomar 12. Panta rhei is a simplified version of the famous greek philosopher Heraclitus’ teachings. It basically means, everything flows. And everything in the Universe is indeed continually on the move, spiraling and shifting through space. Some cosmic objects move a little […]

Astronomers Discover a Rare Planet, Kepler-432b

Astronomers Discover Rare Planet

Astronomers have discovered a rare red planet that has the six times the mass of Jupiter, but is about the same size. Two research groups of Heidelberg astronomers have independently of each other discovered a rare planet. The celestial body, called Kepler-432b, is one of the most dense and massive planets known so far. The […]

Nanoscale Cage Allows Before-and-After Sequencing of DNA Strand

Nanoscale Cage Could Improve Nanopore Technology

Brown University researchers have designed a nanoscale cage that can trap a single DNA strand and allow before-and-after sequencing of the same DNA strand. Providence, Rhode Island (Brown University) — Despite having a diameter tens of thousands of times smaller than a human hair, nanopores could be the next big thing in DNA sequencing. By […]

Study Shows Carbon Emissions Could Increase Risk of Megadroughts

NASA Study Shows Carbon Emissions Could Increase Risk of Megadroughts

A new study from NASA reveals that droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years. NASA scientists used tree rings to understand past droughts and climate models incorporating soil moisture data […]

NASA’s Chandra Views Supernova Remnant G299

Chandra Views Supernova Remnant G299

This new image from NASA’s Chandra X-ray Observatory shows supernova remnant G299.2-2.9. Because the debris fields of exploded stars, known as supernova remnants, are very hot, energetic, and glow brightly in X-ray light, NASA’s Chandra X-ray Observatory has proven to be a valuable tool in studying them. The supernova remnant called G299.2-2.9 (or G299 for […]

Astronomers View the Formation of a Quadruple Star System

The Formation of a Quadruple Star System

A newly published study details the discovery of a wide-separation quadruple system composed of a young protostar and three gravitationally bound dense gas condensations. Amherst, Massachusetts – This week an international team of astronomers reports the first multiple-star system to be observed during the earliest stage of formation. This finding supports model predictions about how […]

Inkjet-Printing System Could Enable Mass-Production of Large-Screen OLED Displays

Inkjet-Printing System Could Enable Mass-Production of OLED Displays

Based on years of Institute research, MIT spinout Kateeva has developed an “inkjet printing” system that could cut manufacturing costs enough to pave the way for mass-producing flexible and large-screen OLED displays. Flexible smartphones and color-saturated television displays were some highlights at this year’s Consumer Electronics Showcase, held in January in Las Vegas. Many of […]

Nano-Antioxidants Quickly Neutralize Superoxides

Study Shows How Particles Quench Damaging Superoxides

A new Rice-led study reveals how nanoparticles can quickly neutralize superoxides that are overexpressed by the body’s cells in response to an injury. Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism. Scientists at Rice University, Baylor […]

Study Reveals Oceanic Carbon Release Helped End the Ice Age

Carbon Release from Ocean Helped End the Ice Age

New research shows that high concentrations of dissolved carbon dioxide in ocean water coincides with rises in atmospheric carbon dioxide and global temperatures at the end of the last ice age, giving scientists valuable insights into how the ocean can affect the carbon cycle and climate change. New techniques are allowing scientists to understand how […]
