Comcast Talks 100 Mbit/s ‘Net Access for Consumers

January 9, 2008

Comcast is planning to offer “wideband” cable Internet access, also known as DOCSIS 3.0, with 100 megabits per second access.

That increased speed will likely be of assistance when Comcast increases its on-demand content. It plans to offer over 1,000 HD selections by the end of 2008, and over 6,000 movies on-demand each month by 2009.

Comcast rolls out 105 Mbps ‘Extreme’ broadband service

April 15, 2011

Comcast on Thursday started rolling out it Extreme 105 Xfinity Internet service, which promises downloads speeds up to 105 Mbps and upload speeds up to 10 Mbps, available in major cities for $105 per month.

Comcast said that Extreme 105 will allow users to download a 4GB high-definition movie in five minutes, compared to an hour and 30 minutes on a 6 Mbps network

Combining materials to make nanoscale 2D electronic components

June 21, 2013

Schematics and experimental images produced by Oak Ridge National Laboratory show defects at the 60-degree grain boundaries in two-dimensional samples of molybdenum disulfide. The defects are 5- and 7-atom dislocation cores; the numbers refer to locations where the atomic arrangements veer from regular six-atom hexagons. Their presence indicates a one-dimensional conductive “wire” that runs along the boundary. In the illustration, the molybdenum atoms are cyan and the sulfur atoms are orange and yellow.

Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of achieving two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide (MDS).

MDS, a semiconductor, is one of three materials needed to make functioning 2D electronic components. The hope is that MDS could be joined with graphene, which has no band gap, and… read more

Combining magnetic sensing and imaging systems may improve brain diagnosis and imaging

July 27, 2012

The innovative MEG-MRI device combines the whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain.

The first system for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology has been developed by a research team headed by Aalto University in Finland.

Merging these two technologies will produce unprecedented accuracy in locating and imaging brain electrical activity non-invasively, and should improve cancer diagnosis and the accuracy of brain mapping of patients, says professor Risto Ilmoniem.

Combining light and sound to create nanoscale optical waveguides

Could lead to chips that combine optical and electronic components
May 24, 2015

Researchers have shown that a DC voltage applied to layers of graphene and boron nitride can be used to control light emission from a nearby atom. Here, graphene is represented by a maroon-colored top layer; boron nitride is represented by yellow-green lattices below the graphene; and the atom is represented by a grey circle. A low concentration of DC voltage (in blue) allows the light to propagate inside the boron nitride, forming a tightly confined waveguide for optical signals.

In a new discovery that could lead to chips that combine optical and electronic components, researchers at MIT, IBM and two universities have found a way to combine light and sound with far lower losses than when such devices are made separately and then interconnected, they say.

Light’s interaction with graphene produces vibrating electron particles called plasmons, while light interacting with hexagonal boron nitride (hBN) produces phonons (sound “particles”).… read more

Combining antennas with solar panels for high efficiency, low weight and volume

antenna-solar cell

Researchers at EPFL have managed to combine telecommunication antennas and solar cells to work together with unprecedented efficiency.

Traditionally, antennas and solar cells have never worked well together, as they have to function independently of each other in order to avoid interference. This has an impact on the weight and size of satellites — the surface area has to be large enough for both antenna systems, which… read more

Combing the Cosmos at High Speed: The Allen Telescope Array

October 12, 2006

The Allen Telescope Array (ATA), a specialized radio telescope now under construction by the SETI Institute and the University of California Berkeley, will be about a hundred times faster than any previous radio search, and will simultaneously pick up all cosmic static between 0.5 and 11.2 gigahertz—a spectral range equivalent to two thousand TV channels.

Researchers from Memorial Sloan Kettering Cancer Center (MSK) are reporting exciting results in the field of cancer immunology.

Positive results from a clinical trial published in The New England Journal of Medicine show that the combination of the immunotherapy drugs ipilimumab (Yervoy™) and nivolumab (Opdivo™) produced significantly better outcomes than ipilimumab alone in patients with advanced melanoma.

Researchers at UCLA Henry Samueli School of Engineering and Applied Science and the California NanoSystems Institute at UCLA have developed a compact and cost-effective RDT-reading device that works in tandem with standard cell phones.

In poor and remote areas of the globe where conventional medical tools like microscopes and cytometers are unavailable, rapid diagnostic tests, or RDTs, are helping to make disease screening quicker and simpler.

RDTs are… read more

Colour coding DNA promises cheaper sequencing

A new technique that color-codes DNA for laser sequencing may offer a faster and cheaper way of sequencing genomes.

Colossal images of the Milky Way Galaxy; 3D images next

British scientists have produced a colossal picture of our Milky Way Galaxy that reveals the detail of a billion stars, BBC News reports.

It is built from thousands of individual images acquired by two UK-developed telescopes operating in Hawaii and in Chile, and concentrates on the dense plane of the galaxy, which means it renders as a very long, very thin strip. An online interactive tool allows you to zoom in… read more

Colossal explosion from supermassive black hole at center of galaxy revealed

black_hole_jet

Two million years ago, a supermassive black hole at the heart of our galaxy erupted in an explosion so immensely powerful that it lit up a cloud 200,000 light years away, a team of researchers led by the University of Sydney has revealed.

The finding is an exciting confirmation that black holes can “flicker,” moving from maximum power to switching off over short periods of… read more
