Dark Energy Camera Captures its First Images

first images captured by the Dark Energy Camera

Located on a mountaintop in Chile, the newly-constructed Dark Energy Camera is the most powerful sky-mapping machine ever created and has captured and recorded its first rays of light from distant galaxies. When the Dark Energy Camera (DECam) opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, […]

Prevalence of Multi-Drug Resistant E. Coli Rising ICAAC 2 Reports

Ecoli-close-up

Infections with multi-drug resistant E. coli, which is also known as ESBL (extended spectrum beta-lactamase), have been assumed to be a hospital phenomenon. A recent analysis presented at The Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) surveyed records from five hospital across the USA (New York, Pennsylvania, Michigan, Texas, and Iowa) and identified 291 […]

Probable Distance to Remnant of Kepler’s Supernova

An image of the Kepler supernova remnant

Scientists at CfA have taken an important step in determining the distance of the remnant of Kepler’s supernova, concluding that the remnant distance is probably greater than about twenty-one thousand light-years. Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the […]

Atomic Bond Types Clearly Discernible Thanks to Single-Molecule Images

atomic-bonds

A team from IBM in Zürich has released images they captured of single-molecules that are so detailed that the type of atomic bonds between their atoms can be discerned. The scientists published their findings in the journal Science. The same IBM team took the first ever single-molecule images in 2009 and most recently published the […]

NASA’s Opportunity Discovers Geological Mystery on Mars

Puzzling Little Martian Spheres nicknamed 'Blueberries'

NASA’s Opportunity rover discovered puzzling spherical objects on Mars at a rock outcrop called Kirkwood. The spherules vary in composition, concentration, distribution and structure from the spherules that were discovered eight-and-a-half years earlier and nicknamed “blueberries.” Pasadena, California — NASA’s long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers. […]

Raytheon JLENS Defense System Features Aerostats

JLENS-Raytheon-in-air

US Defense contractor Raytheon recently successfully tested the Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS) over the Great Salt Lake in Utah. The test involved the radar’s ability to track multiple fast and high speed vessels, potentially giving ship commanders situational awareness of all threats that he or she might face. […]

Honeybees Switch Roles within the Hive

honeybee-forager

Honeybees exhibit subtle differences in their DNA, which is tied to their roles within the hive. These DNA modifications, which are normally fixed, can be changed and could be the first examples of reversible DNA changes associated to behavior. The scientists published their findings in the journal Nature Neuroscience. All honeybees (Apis mellifera) are born […]

Mother’s Presence Increases Survivability of Male Orca Offspring

mother-son-orca-survivability

A study of 600 orcas revealed that a mother’s presence increases a son’s change of survival significantly. The mothers are driven by an innate drive to ensure that they have as many descendants as possible, and this might compel them to look out for their adult young. The evolutionary benefit of keeping watch over their […]

Hyenas Might Be As Intelligent As Some Primates

hyenas-problem-solving

While hyenas have often been depicted as slobbering, dim-witted fools in animated movies, a new study shows that the African carnivores are adept at problem-solving, and can even count. This makes scientists believe that Hyaenidae could have comparable intelligence levels to some primates. The scientists published their findings in the journal Proceedings of the Royal Society […]

Study Examines How Global Warming Will Affect Tropical Rainfall

Tropical Storm Fay in 2008

A new study from scientists at MIT uses model simulations and observations to estimate the how global warming will affect extreme precipitation, finding that with every 1 degree Celsius rise in temperature, tropical regions will see 10 percent heavier rainfall extremes. Extreme precipitation in the tropics comes in many forms: thunderstorm complexes, flood-inducing monsoons and […]

Pr0201b and Pr0211b Orbiting Sun-Like Stars in the Beehive Cluster

planets orbiting sun-like stars

For the first time, a team of astronomers have spotted two new “Hot Jupiter” planets, called Pr0201b and Pr0211b, orbiting sun-like stars in the Beehive Cluster, also called the Praesepe. Pasadena, California — NASA-funded astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. The findings offer the […]

Superhydrophobic Coating Allows Boiling Water without the Creation of Bubbles

boiling water without bubbles

Water can be made to boil without any bubbling if a boiling surface is specifically treated so that the vapor cushion does not break down. This is linked to the Leidenfrost effect. The scientists published their findings in the journal Nature. The surface needs to be very water-repellent and the effect might be used to […]

IAU Changes the Astronomical Unit from Equation to Number

graph-astronomical-unit

Astronomers have redefined one of the most commonly used stellar distances, the astronomical unit (AU). Based on the rough distance from Sol to Earth, AU has been transformed from a confusing equation to simple number. Astronomers had adopted this simplification at this summer’s past International Astronomical Union’s meeting in Beijing, China, making the astronomical unit […]
