Scientists Reproduce the Building Blocks of Life

The Building Blocks of Life Reproduced in a Laboratory

Scientists from NASA’s Ames Research Center have demonstrated for the first time that they can make uracil, cytosine, and thymine, all three components of RNA and DNA, non-biologically in a laboratory under conditions found in space. NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary […]

New Research Reveals Two Solar Wind Jets in the Heliosphere

NASA Study Finds Two Solar Wind Jets in the Heliosphere

New research shows that the heliosphere is dominated by two giant jets of material shooting backwards over the north and south poles of the sun, which are confined by the interaction of the sun’s magnetic field with the interstellar magnetic field. As the sun skims through the galaxy, it emits charged particles in a stream […]

Physicists Demonstrate Ponderomotive Spectroscopy

Forbidden Atomic Transitions Driven by an Intensity-Modulated Laser Trap

In a new study, researchers at the University of Michigan detail how they used light to study and control matter with 1,000 times better resolution and precision than previously possible. Physicists at the University of Michigan have demonstrated “ponderomotive spectroscopy,” an advanced form of a technique that was born in the 15th century when Isaac […]

New Technique Analyzes Clouds Around Exoplanets

New Technique Allows Analysis of Clouds around Exoplanets

Research from MIT details a new technique that analyzes data from NASA’s Kepler space observatory to determine the types of clouds on planets that orbit other stars. Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system, thanks […]

Study Shows How Quickly New Fat Cells Are Created

Yale Study Shows How Created Quickly New Fat Cells Are Created

New research from Yale University looks at the creation and expansion of white fat cells, and how these fat cells are created. Once fat cells form, they might shrink during weight loss, but they do not disappear, a fact that has derailed many a diet. Yale researchers in the March 2 issue of the journal […]

NASA Spacecraft Nears Dwarf Planet Ceres

NASA’s Dawn Spacecraft Nears Historic Dwarf Planet Arrival

NASA’s Dawn spacecraft is set to be the first mission to successfully visit a dwarf planet when it enters orbit around Ceres on Friday, March 6. NASA’s Dawn spacecraft has returned new images captured on approach to its historic orbit insertion at the dwarf planet Ceres. “Dawn is about to make history,” said Robert Mase, […]

ALMA and VLT Reveal Dusty and Evolved Galaxy

Hubble Views Galaxy Cluster Abell 1689

New observations from the Very Large Telescope along with the Atacama Large Millimeter/submillimeter Array have revealed a dusty galaxy seen when the Universe was just 700 million years old. One of the most distant galaxies ever observed has provided astronomers with the first detection of dust in such a remote star-forming system and tantalizing evidence […]

Life Possible on Saturn’s Moon Titan

Life Possible on Titan

In a new study, chemical engineers and astronomers from Cornell University reveal that Titan could harbor methane-based, oxygen-free cells that metabolize, reproduce and do everything life on Earth does. Liquid water is a requirement for life on Earth. But in other, much colder worlds, life might exist beyond the bounds of water-based chemistry. Taking a […]

FIT Treadmill Score Gauges Risk of Dying Based on Treadmill Exercise Performance

Treadmill Performance Predicts Mortality

A new formula gauges a person’s 10-year risk of dying by estimating a person’s ability to exercise on a treadmill at an increasing speed and incline. Analyzing data from 58,000 heart stress tests, Johns Hopkins cardiologists report they have developed a formula that estimates one’s risk of dying over a decade based on a person’s […]

3D Graphene Aerogel Catalyst Shows Promise for Fuel Cells

3D Aerogel Shows Promise for Fuel Cells

New research from Rice University shows that graphene nanoribbons formed into a three-dimensional aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells. A team led by materials scientist Pulickel Ajayan and chemist James Tour made metal-free aerogels from graphene nanoribbons and various levels of boron and nitrogen to test their electrochemical […]

Scientists Reverse Type 2 Diabetes and Fatty Liver Disease

Researchers Reverse type 2 Diabetes and Fatty Liver Disease

A newly published study reveals how scientists from Yale University developed a controlled-release oral therapy that reversed type 2 diabetes and fatty liver disease in rats. Existing therapies for type 2 diabetes, and the closely associated conditions of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), have had limited success at treating the root […]

Hubble Picture of the Week: A Young Star Takes Center Stage

New Hubble Image of V1331 Cyg

This newly released Hubble images shows the T Tauri star known as V1331 Cyg. With its helical appearance resembling a snail’s shell, this reflection nebula seems to spiral out from a luminous central star in this new NASA/ESA Hubble Space Telescope image. The star in the center, known as V1331 Cyg and located in the […]

Astrophysicists Investigate Where Stars Form in Merging Galaxies

The Spatial Extent of Induced Star Formation

Researchers from the Harvard-Smithsonian Center for Astrophysics simulated galaxy collisions under a wide range of conditions in order to investigate the question of where the induced star formation is located. Collisions between galaxies, and even less dramatic gravitational encounters between them, are recognized as triggering star formation. Observations of luminous galaxies, powered by starbursts, are […]

First Time Solutions Provide New Insight in Black Hole Collisions

New Insight Found in Black Hole Collisions

In a new study, astrophysicists provide for the first time solutions to decades-old equations that describe conditions as two black holes in a binary system orbit each other and spiral in toward a collision. New research by Dr. Michael Kesden, assistant professor of physics at UT Dallas, and his colleagues provides revelations about the most […]
