Small Impacts Likely Erased Much of Earth’s Primordial Atmosphere

Small Impacts Likely Erased Much of the Earth’s Primordial Atmosphere

A newly published study reveals that small space rocks, or planetesimals, may have bombarded Earth around the time the moon was formed, kicking up clouds of gas with enough force to permanently eject small portions of the atmosphere into space. Today’s atmosphere likely bears little trace of its primordial self: Geochemical evidence suggests that Earth’s […]

New Study Shows Brain stimulation Counteracts Dangerous Side Effect of Seizures

Brain Stimulation Can Restore Consciousness after a Seizure

In a newly published study, neurologists from Yale University have reawakened rats after seizures by stimulating parts of the brain involved in conscious awareness. The research may lead to treatments for individuals with epilepsy. Loss of consciousness is a common and dangerous side effect of epileptic seizures. A study published this week in the journal […]

Jupiter’s Great Red Spot – Just a Sunburn?

Research Shows Sunlight Produces the Color of Jupiter's Great Red Spot

Using a combination of data from Cassini’s December 2000 Jupiter flyby and laboratory experiments, new research suggests effects of sunlight produce the color of Jupiter’s Great Red Spot. The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to […]

NASA Prepares for Orion Flight Test and the Journey to Mars

NASA Prepares to Send Humans to Mars

NASA scientists are developing the capabilities needed to send humans to an asteroid by 2025 and to Mars by the 2030s. In the not-too-distant future, astronauts destined to be the first people to walk on Mars will leave Earth aboard an Orion spacecraft. Carried aloft by the tremendous power of a Space Launch System rocket, […]

Microbullets Demonstrate Graphene’s Energy Absorbing Strength

Microbullets Confirm the Strength of Graphene

A newly published study from Rice University shows that graphene is 10 times better than steel at absorbing the energy of a penetrating projectile. Graphene’s great strength appears to be determined by how well it stretches before it breaks, according to Rice University scientists who tested the material’s properties by peppering it with microbullets. The […]

Astronomers Develop a New Method to Evaluate the Turbulence of the Hot Intracluster Gas

New Method to Evaluate the Turbulence of the Hot Intracluster Gas

Using data from the Chandra X-Ray Observatory, astronomers from the Harvard-Smithsonian Center for Astrophysics have pioneered a new method to evaluate the turbulence of the hot intracluster gas. Most galaxies lie in clusters, groupings of a few to many thousands of galaxies. Our Milky Way galaxy itself is a member of the “Local Group,” a […]

Astronomers Use Ground-Based Telescope to Measure Super-Earth Transit

Astronomers Measure Super-Earth Transit Using a Ground-Based Telescope

Using the 2.5-meter Nordic Optical Telescope, astronomers have measured transit of exoplanet 55 Cancri e – this is the first time that a super-Earth transit has been measured from a ground-based telescope. Cambridge, Massachusetts – Astronomers have measured the passing of a super-Earth in front of a bright, nearby Sun-like star using a ground-based telescope […]

New Biotech Innovation Reduces Unpredictability in Biological Circuits

New Biotech Device Could Make Large Biological Circuits Practical

A new biotech device from MIT reduces the unpredictability of biological components and could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts. Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different […]

Van Allen Probes Reveal an Impenetrable Barrier in Space

NASA Spots an Impenetrable Barrier in Space

Using NASA’s Van Allen Probes, new research reveals that the Van Allen radiation belts contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth. This movie shows how particles move through Earth’s radiation belts, the large donuts around Earth. The sphere in the middle shows a cloud of colder material […]

Mysterious Ecosystem May Hold Clues to Alien Life

Deep Sea Shrimp May Hold Clues to Alien Life

Scientists at NASA’s Jet Propulsion Laboratory reveal that the extreme oasis of life deep in the Caribbean Sea may hold clues to life on other planetary bodies, including Jupiter’s moon Europa. At one of the world’s deepest undersea hydrothermal vents, tiny shrimp are piled on top of each other, layer upon layer, crawling on rock […]

Study Shows Low level Drinking Not Associated with Higher Risk of Poor Birth Outcomes

Low Level Drinking Not Associated with Higher Risk of Birth Defects

Newly published research shows that low to moderate alcohol consumption during pregnancy is not associated with an increased risk of specific birth outcomes and measures of fetal growth. Heavy alcohol consumption during pregnancy has long been linked to a range of developmental problems and birth defects including fetal alcohol syndrome (FAS), low birth weight, and […]
