Neuroscientists Plant False Memories in the Brains of Mice

Neuroscientists Plant False Memories

In a new study, neuroscientists plant false memories in the brains of mice, showing that the brain’s neural mechanism underlying the recall of the memory is the same whether it’s a false or genuine memory. The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony […]

New Theoretical Models Could Aid in the Hunt for Habitable Planets

Theoretical Protosun Models Could Aid in the Search for Habitable Planets

A recently published study details new theoretical models that reveal how an outburst event in the Sun’s early years could help in the hunt for habitable planets outside of our solar system. Washington, D.C. — Comets and meteorites contain clues to our solar system’s earliest days. But some of the findings are puzzle pieces that […]

ALMA Reveals the Mystery of Missing Massive Galaxies

Starburst Data Sheds New Light on the Mystery of Missing Massive Galaxies

Using data from the ALMA telescope, astronomers shed new light on galaxy formation, finding evidence that some growing galaxies spew out more gas than they take in. New observations from the ALMA telescope in Chile have given astronomers the best view yet of how vigorous star formation can blast gas out of a galaxy and […]

Astrophysicists Document the Immense Power of Quasar Radiation

Dartmouth Researchers Shed New Light on Quasars

Using data from the Southern African Large Telescope and NASA’s WISE, astrophysicists documented the immense power of quasar radiation, seeing for the first time the actual extent to which these quasars and their black holes can affect their galaxies. Quasars are among the brightest, oldest, most distant, and most powerful objects in the universe. Powered […]

New Research Explains Acceleration of Greenland’s Inland Ice

Surprising Acceleration of Greenlands Inland Ice

By developing a new model investigate the effects of meltwater on Greenland glaciers, researchers discovered that meltwater warms the ice sheet, which then softens, deforms, and flows faster. This animation shows how ice is naturally transported from interior topographic divides to the coast via glaciers. The colors represent the speed of ice flow, with areas […]

Biomechanics of Dental Features and Tooth Wear

Biomechanics of Dental Features and Tooth Wear

A team of biologists examined the functional biomechanics of dental features and tooth wear, finding that the biomechanical requirements on teeth change during one’s lifetime. Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Senckenberg Research Institute in Frankfurt am Main, Germany, have conducted stress analyses on gorilla teeth of […]

Enhanced Hollow-Core Fiber Features Performance-Enabling Properties

Hollow Core Optical Fiber to Enable High Power Sensors

Researchers from Honeywell International have modified hollow-core fiber, dramatically improving performance and making it the first hollow-core fiber to demonstrate single-spatial-mode, low-loss and polarization control. The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and […]

Researchers Link Genetic Mutation to Severe Obesity

Genetic Mutation Linked to Severe Obesity

Researchers have identified a genetic cause of severe obesity, finding that mice with the genetic mutation gained weight even while eating the same amount of food as their normal counterparts. Harvard Medical School researchers at Boston Children’s Hospital have identified a genetic cause of severe obesity that, though rare, raises new questions about weight gain […]

Martian Valleys Likely Caused by Ancient Snowfall or Rain

Ancient Snowfall Likely Caused Water Carved Valley on Mars

In a new study, scientists from Brown University suggest that certain valleys on Mars appear to have been caused by runoff from orographic precipitation. Providence, Rhode Island (Brown University) — Valley networks branching across the Martian surface leave little doubt that water once flowed on the Red Planet. But where that ancient water came from […]
