“Cheetah-Cub Robot” Runs Like a Cat

EPFL Cheetah Cub Robot

In this short video, researchers from EPFL’s Biorobotics Laboratory reveal a small-size quadruped prototype robot, which they call a “cheetah-cub robot.” Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL’s four-legged “cheetah-cub robot” has the same advantages as its model: it is small, light and fast. Still in its experimental stage, the robot […]

Hubble Views Two Galaxies Colliding

Hubble Views Two Galaxies Colliding

In this newly released image, the Hubble Space Telescope views two galaxies that are currently colliding to form a new one. The contorted object captured by Hubble in this picture is IRAS 22491-1808, also known as the South America Galaxy. It is an ultra-luminous infrared galaxy (ULIRG) that emits a huge amount of light at […]

NASA Study Bridges the Gap Between Theory and Black Hole Observations

NASA Study Explains Decades of Black Hole Observations

A newly published study bridges the gap between theory and black hole observation, confirming how stellar-mass black holes produce their highest-energy light by demonstrating that both hard and soft X-rays inevitably arise from gas spiraling toward a black hole. A new study by astronomers at NASA, Johns Hopkins University and Rochester Institute of Technology confirms […]

Fast-Acting Virus Targets Most Melanoma Tumors

Fast Acting Virus Eradicates Most Melanoma Tumors

In a newly published study, Yale University researchers show that a fast-acting virus targets most melanoma tumors after injection into the blood stream of mice. Yale researchers eradicated most melanoma tumors by exposing them to a fast-acting virus, they report in the June 15 edition of the Journal of Virology. Melanoma is the deadliest type […]

Researchers Control Magnetic Clouds in Graphene, Switch Magnetism On and Off

Researchers Switch Magnetism On and Off in Graphene

Scientists from the University of Manchester have shown for the first time that magnetic clouds in graphene can be controllably dissipated and then condensed back, allowing researchers to work towards transistor-like devices in which information is written down by switching graphene between its magnetic and non-magnetic states. In a report published in Nature Communications, a […]

Astronomers Obtain the Most Accurate Distance for a Radio Pulsar

Astronomers Set Record Using VLBA to Accurately Measure the Distance of a Pulsar

Using the Very Long Baseline Array, astronomers have obtained the most accurate distance for a radio pulsar to date, showing that pulsar PSR J2222-0137 is 871.4 light-years from Earth – 15% closer than previous estimates. An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to […]

Hubble Reveals Evidence of a Planet Forming 7.5 Billion Miles from Its Star

Hubble Discovers Planet Forming Far Away from Its Star

Scientists using the Hubble Space Telescope have discovered evidence that a planet is forming 7.5 billion miles away from its star in a vast protoplanetary disk of gas and dust, a finding that could challenge current theories about planet formation. Of the almost 900 planets outside our solar system that have been confirmed to date, […]

Astronomers Measure the Density of Dark Matter in Galaxy Clusters

Study Sheds New Light on Dark Matter

In a new study, astronomers detail their measurements of the density of dark matter in galaxy clusters, finding that the density of dark matter decreases gently from the center of these cosmic giants out to their diffuse outskirts. Astronomers at the University of Birmingham, Academica Sinica in Taiwan, and the Kavli Institute of Physics and […]

Data Indicates Temperatures Rise and Fall Twice a Day on Mars

Temperatures on Mars Rise and Fall Twice a Day

Data from NASA’s Mars Reconnaissance Orbiter has indicated that temperatures rise and fall twice a day on Mars, with a rise during the nighttime as well as during daytime resulting from the thin water-ice clouds that form in the equatorial region of Mars. Pasadena, California — Researchers using NASA’s Mars Reconnaissance Orbiter have found that […]
