Calculations Show the Ideal Time to Study the Cosmos

ideal time to study the cosmos was more than 13 billion years ago

The time to study the cosmos is now. New calculations show that the expansion of the cosmos is accelerating, galaxies are being pushed beyond our horizon and the scale of gravitationally unbound structures is growing larger and will eventually stretch beyond our horizon as well. Cambridge, Massachusetts – The universe is a marvelously complex place, […]

Fiber Optic Probe Measures Carotenoids in the Skin

new technology that measures a biomarker by simply bouncing blue laser light off the skin

New technology that measures a biomarker by simply bouncing blue laser light off the skin provides fast, painless and highly accurate results. Based on resonance Raman spectroscopy technology, the device uses computer software and a flexible fiber optic probe that is held against the palm for about 30 seconds while the light interacts with carotenoids […]

Physical Properties of Stem Cells Predict What They Will Become

Physical properties predict stem cell use

New research from Brown University shows that the physical properties of adult stem cells derived from fat, such as liposuction waste, can predict whether they will turn into bone, cartilage, or fat, leading to a potential method of concentrating them for use in specialized healing. Providence, Rhode Island (Brown University) — To become better healers, […]

Scientists Restore Basic Elements of Vision in Live Mice

Scientists restore basic vision in mice

A new study from a team of scientists hints that people blinded by optic nerve damage from trauma or glaucoma might be able to regain some visual function in the future. The team was able grow optic nerve fibers to the full length of the visual pathway and restored some basic elements of vision in […]

Oxygen Depletion and Acidification Accelerate Coral Death

coral death by a deadly chain reaction

To better understand how to protect coral reefs, a team of microbiologists are investigating how environmental changes, such as oxygen depletion and ocean acidification, create a chain reaction that leads to coral death. Most people are fascinated by the colorful and exotic coral reefs, which form habitats with probably the largest biodiversity. But human civilization […]

Opportunity on the Western Rim of Endeavour Crater

Mars Rover Opportunity catches its own late-afternoon shadow in Endeavour Crater on Mars

NASA’s Mars Exploration Rover Opportunity has been exploring the edge of Endeavour Crater since August 2011, taking images and recording data about the environment. Like a tourist waiting for just the right lighting to snap a favorite shot during a stay at the Grand Canyon, NASA’s Mars Exploration Rover Opportunity has used a low sun […]

Stiffer Pavements Could Reduce Fuel Consumption and CO2 Emissions

pavement deflection under vehicle tires makes for a continuous uphill drive that increases fuel consumption

A team of engineers used mathematical modeling to look at the effect of pavement deflection on vehicle fuel consumption across the entire U.S. road network, finding that stiffer pavements could reduce vehicle fuel consumption and result in an annual decrease in CO2 emissions of 46.5 million metric tons. A new study by civil engineers at […]

Mathematical Framework Formalizes Loop Perforation Technique

Loop perforation speeding up programs by skipping instructions

As computer scientists continue to look for ways to enhance performance, Martin Rinard and the Artificial Intelligence Laboratory hope their technique of loop perforation, the speeding up programs by skipping instructions, will be accepted by developers. Two years ago, Martin Rinard’s group at MIT’s Computer Science and Artificial Intelligence Laboratory proposed a surprisingly simple way […]

Physicists Create a Condensate of Erbium

team successfully creates a condensate of the exotic element erbium

A research team at the University of Innsbruck is the first to successfully create a condensate of the element erbium, making it the third chemical element that the physicists in Innsbruck have condensated successfully in the last few years. Ultracold quantum gases have exceptional properties and offer an ideal system to study basic physical phenomena. […]

Magnetometers Ready for NASA’s MAVEN Mission

MAVEN magnetometers

In preparation for the 2013 launch, scientists and engineers at NASA worked diligently to complete the magnetometers on schedule for the MAVEN mission. The magnetometers will measure the magnetic field at the location of the spacecraft and are important in understanding how the solar wind interacts with the planet’s atmosphere, causing charged particles to escape. […]

Likelihood of Nuclear Accident 200 Times Greater than Previously Thought

Probability of contamination from severe nuclear reactor accidents is higher than expected

Based on new calculations from scientists at the Max Planck Institute, the likelihood of a nuclear accident is far greater than previously thought. The research shows that nuclear accidents, such as core meltdowns, may occur every 10 to 20 years, 200 times more often than estimated in the past. Catastrophic nuclear accidents such as the […]

27-Foot Long Crocodylus Thorbjarnarsoni Roamed Kenya

Crocodylus_thorbjarnarsoni-skull

The remains of the largest crocodilian known to have existed, Crocodylus thorbjarnarsoni, were unearthed in the Turkana Basin, in Kenya. The large crocodile was big enough to swallow humans whole, and probably did as much two to four million years ago, from the mid-Pliocene to the early Pleistocene eras. The enormous horned crocodilian, named Crocodylus […]

New Technique Leads to the Discovery of 5 New Pulsars

New Way to Discover Pulsars

By combining observations from the Large Area Telescope and the Parkes Radio Telescope in Australia, scientists have found a new technique for hunting pulsars. The team has already found five new “millisecond” pulsars, including one particularly intriguing object, proving that the technique is successful. The Large Area Telescope (LAT), built by SLAC for the Fermi […]
