Human Heart Precursor Cells Regenerate Decellularized Mouse Heart

Mouse Heart Beats Again after Regeneration with Human Heart Precursor Cells

A newly published study details how researchers used human heart precursor cells to get a decellularized mouse heart to beat again. Pittsburgh – For the first time, a mouse heart was able to contract and beat again after its own cells were stripped and replaced with human heart precursor cells, said scientists from the University […]

Mars Express Captures a Radar View of the Southern Highlands of Mars

Mars Express Captures a Radar View of the Southern Highlands of Mars

Mars Express has provided scientists with a radar view of the southern highlands of Mars, showing what lies beneath the surface. There is much more to Mars than meets the eye. By using the radar on Mars Express, we can see several kilometers below the surface to see what lies beneath. The radar creates subsurface […]

ESO’s VLT Views Galaxies NGC 799 and NGC 800

ESOs VLT Views Galaxies NGC 799 and NGC 800

Using the FORS1 instrument on the 8.2-metre ESO Very Large Telescope, astronomers captured a new image of galaxies NGC 799 and NGC 800. This beautiful image portrays the galaxies NGC 799 (below) and NGC 800 (above) located in the constellation of Cetus (The Whale). This pair of galaxies was first observed by the American astronomer […]

Physicists Propose Higgs Boson ‘Portal’ to Help Explain Dark Energy

Scientists Propose Higgs Boson Portal to Help Explain Dark Energy

A newly published study explores how the recently discovered Higgs boson may provide a possible “portal” to physics that will help explain some of the attributes of dark energy. One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has […]

Hubble Views a Very Young Star Being Born

Hubble Views a Very Young Star Being Born

In this newly released image Hubble views a young star being born in the gas, dust, and ices of the dark cloud LDN 43. Don’t be fooled by the title; the mysterious, almost mystical bright light emerging from these thick, ominous clouds is actually a telltale sign of star formation. Here, a very young star […]

UC Berkeley Study Links Sleep Deprivation to Junk Food Cravings

Study Links Sleep Deprivation to Junk Food Cravings

A UC Berkeley has linked sleep deprivation to junk food cravings, finding that high-level brain regions required for complex judgments and decisions become blunted by a lack of sleep, while more primal brain structures that control motivation and desire are amplified. Berkeley — A sleepless night makes us more likely to reach for doughnuts or […]

Atomic Clock Simulates Quantum Magnetism

Atomic Clock Simulates Quantum Magnetism

For the first time, a team of scientists at JILA have used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system. Atomic clocks now join a growing list of physical systems that can be used for modeling and perhaps eventually explaining the quantum mechanical behavior of exotic […]
