Modified RNA Extends Telomeres in Human Cells, Turns Back Aging Clock

Telomere Extension Turns Back Aging Clock in Cultured Human Cells

Biologists from the Stanford University School of Medicine used a modified type of RNA to demonstrate a way to lengthen human telomeres by as much as 1,000 nucleotides, turning back the internal clock in these cells by the equivalent of many years of human life. A new procedure can quickly and efficiently increase the length […]

Physicists Slow Down the Speed of Light

Physicists Slow Down the Speed of Light Traveling Through Air

By applying a mask to an optical beam to give photons a spatial structure, physicists have demonstrated that spatially structured photons travel slower than the speed of light in free space. Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass. However, […]

Research Shows a Significant Increase in the Amount of Water “Pouring” Out of Comet 67P

Rosetta Comet Pouring More Water Into Space

Data from ESA’s Rosetta spacecraft revelas that there has been a significant increase in the amount of water “pouring” out of comet 67P/Churyumov-Gerasimenko, the comet on which the Rosetta mission’s Philae lander touched down in November 2014. There has been a significant increase in the amount of water “pouring” out of comet 67P/Churyumov-Gerasimenko, the comet […]

Hubble Image of the Week: The Polar Ring of Arp 230

Hubble Views Lenticular Galaxy Arp 230

This newly released Hubble image shows Arp 230, which also known as IC 51. Arp 230 is a galaxy of an uncommon or peculiar shape, and is therefore part of the Atlas of Peculiar Galaxies produced by Halton Arp. Its irregular shape is thought to be the result of a violent collision with another galaxy […]

CID-42: A Recoiling, Supermassive Black Hole?

CID-42 A Recoiling Black Hole

New research from the Harvard-Smithsonian Center for Astrophysics provides new insights from deep VLA data on the potentially recoiling black hole CID-42 in the COSMOS field. When galaxies collide, the central supermassive black holes that reside at their cores will end up orbiting one another in a binary pair, at least according to current simulations. […]

Reducing Myc Gene Activity Significantly Increases the Healthy Lifespan of Mice

Reducing Myc Gene Activity Extends Healthy Lifespan in Mice

In a newly published study, scientists reveal that reducing Myc gene activity extended the lifespan of mice. The mice lived 15 percent longer on average — 20 percent longer for females and 10 percent longer among males. Providence, Rhode Island (Brown University) — A team of scientists based at Brown University has found that reducing […]

Small Helicopter Could Improve the Exploration of Mars

Small Helicopter Could Scout for Future Mars Rovers

Engineers at NASA’s Jet Propulsion Laboratory are working on a small helicopter that could ‘scout’ a trail for future Mars rovers. Getting around on Mars is tricky business. Each NASA rover has delivered a wealth of information about the history and composition of the Red Planet, but a rover’s vision is limited by the view […]

First Comprehensive 3D Map of Layers Deep Inside the Greenland Ice Sheet

Greenland's Ice Layers Mapped in 3D

Using ice-penetrating radar data and data collected from earlier airborne campaigns, scientists have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet. Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of what Earth’s climate was like at […]

Curiosity Rover Marks 11th Anniversary with Hilltop Panorama

Curiosity Marks 11th Anniversary with Hilltop Image

In celebration of its 11th anniversary on Mars, NASA’s Curiosity rover captured this panorama view from the top of “Cape Tribulation.” A panorama from one of the highest elevations that NASA’s Mars Exploration Rover Opportunity has reached in its 11 years on Mars includes the U.S. flag at the summit. The view is from the […]

Evidence of Weibel-Generated Magnetic Fields

Scientists Peer into Cosmic Magnetic Fields

Using a proton probe to directly image electromagnetic fields, scientists from the Lawrence Livermore National Laboratory present evidence of Weibel-generated magnetic fields that grow in opposing, initially unmagnetized plasma flows from laser-driven laboratory experiments. The generation of cosmic magnetic fields has long intrigued astrophysicists. Since it was first described in 1959, a phenomenon known as […]

Genomically Recoded Organisms Ensure GMOs Can Be Safely Confined in the Environment

Synthetic Amino Acid Enables Safe Biotechnology Solutions

New research details the construction of a series of genomically recoded organisms (GROs) whose growth is restricted by the expression of multiple essential genes that depend on exogenously supplied synthetic amino acids. These GROs will ensure genetically modified organisms can be safely confined in the environment, overcoming a major obstacle to widespread use of GMOs […]

Yale Astronomers Identify the First “Changing Look” Quasar

Black Hole Creates Changing Look Quasar

A team of astronomers from Yale University have identified the first “changing look” quasar, a gleaming object in deep space that appears to have its own dimmer switch. The discovery may offer a glimpse into the life story of the universe’s great beacons. Quasars are massive, luminous objects that draw their energy from black holes. […]

Gullies Suggest Water Flowed on the Surface of Vesta

Gullies Suggest Past Water on Vesta

A newly published study shows evidence that transient water flowed on the surface of Vesta, in a debris-flow-like process, and left distinctive geomorphologic features. Protoplanet Vesta, visited by NASA’s Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its […]

NASA Data Reveal Subglacial Lakes Refilling in Greenland

Subglacial Lakes Seen Refilling in Greenland

New research found evidence of a drained and refilled subglacial lake in Greenland, revealing that surface meltwater can be trapped and stored at the bed of an ice sheet. Sensible and latent heat released by this trapped meltwater could soften nearby colder basal ice and alter downstream ice dynamics. Scientists using satellite images and data […]

Milky Way Could Be a “Galactic Transport System”

Milky Way Could Be a Giant Wormhole

A newly published theory reveals that the Milky Way could contain a space-time tunnel, and that the tunnel could even be the size of the galaxy itself. Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel, have you seen “Interstellar?”) and, if that were true, it would […]

MIT Research Reveals Natural Impediment to Long-Term Sequestration of Carbon Dioxide

Study Finds Natural Impediment to Long-Term Sequestration of Carbon Dioxide

A new study reveals a natural impediment to the long-term sequestration of carbon dioxide, showing that as carbon dioxide works its way underground only a small fraction of the gas turns to rock. The remainder of the gas stays in a more tenuous form. Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide […]
