Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own sun. By making detailed observations of the protoplanetary disk surrounding the star known as HD 107146, the astronomers detected an unexpected increase in the concentration of millimeter-size dust grains in the disk's outer reaches.
When the people whose houses hug the narrow warren of streets paralleling the busiest urban freeway in America began to see bumper-to-bumper traffic crawling by their homes a year or so ago, they were baffled. When word spread that the explosively popular new smartphone app Waze was sending many of those cars through their neighborhood in a quest to shave five minutes off a daily rush-hour commute, they were angry and ready to fight back.
New Star Environmental has introduced their piston-powered oil-free Rocker 300 laboratory vacuum pump that can provide vacuum and pressure in just one unit. The vacuum pump features a noise level of only 50 dB. The Rocker 300 is virtually maintenance-free because of the oil-free design.
Porvair Sciences low-profile 96-well deep well plate achieves a storage volume of 1.1 mL/well in a height of just 27 mm, enabling more plates to be stacked or stored in a given space. Manufactured from extractable-free polypropylene in an ISO 10,000-approved cleanroom environment, the low-profile plates undergo extensive quality testing to ensure they are certified free from DNase, RNase and endotoxin contamination.
In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a quantum Internet. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum Internet is control of the shape of these photons.
A species of small fish uses a homemade coral-scented cologne to hide from predators, a new study has shown, providing the first evidence of chemical camouflage from diet in fish. Filefish evade predators by feeding on their home corals and emitting an odor that makes them invisible to the noses of predators, the study found.
A project by students from The Univ. of Western Australia and Mars One astronaut candidate Josh Richards has reached the finals of an international competition to land vital experiments on the Red Planet. The Helena Payload project, which aims to generate the first breathable air on Mars, is one of 10 finalists in the Mars One University Competition and is the only successful entry from the southern hemisphere.
Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo: the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique developed by researchers can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
In a triumph for cell biology, researchers have assembled the first high-resolution, 3-D maps of entire folded genomes and found a structural basis for gene regulation—a kind of “genomic origami” that allows the same genome to produce different types of cells. The research appears online in Cell.
An ancient meteorite and high-energy x-rays have helped scientists conclude a half century of effort to find, identify and characterize a mineral that makes up 38% of the Earth. And in doing so, a team of scientists clarified the definition of the Earth's most abundant mineral, a high-density form of magnesium iron silicate, now called Bridgmanite, and defined estimated constraint ranges for its formation.
For decades, the mantra of electronics has been smaller, faster, cheaper. Today, Stanford Univ. engineers add a fourth word: taller. A Stanford team revealed how to build high-rise chips that could leapfrog the performance of the single-story logic and memory chips on today's circuit cards.
A way to use weak molecular bonding interactions to create well-ordered and stable metal–organic monolayers with optoelectronic properties has been found by researchers from the RIKEN Surface and Interface Science Laboratory.
ESA is developing technologies for advanced human–machine interaction to transfer the human sense of touch to space.
Earlier this month, the NTSB released its Aircraft Incident Report on a fire aboard a Japan Airlines Boeing 787, concluding that the fire was probably caused by an internal short circuit within a cell of the lithium-ion battery.
Stanford University's Precourt Institute for Energy, Precourt Energy Efficiency Center and TomKat Center for Sustainable Energy have awarded eight seed grants totaling about $1.5 million for promising new research in clean technology and energy efficiency.
