New Qualcomm chips pack high-end features for lower-cost earbuds

Posted by in categories: computing, transportation

Qualcomm is getting ready to usher in a new generation of super low-power Bluetooth earbud chips.

The QCC514X and the QCC304X will support Qualcomm’s TrueWireless Mirroring technology. This means that wireless connectivity is secured with a single earbud that is paired with another. When the user removes the primary earbud, the other mirroring bud takes over the connection without any interruption.

The units will also support active control, or noise cancellation, bringing the popular feature commonly found on high-end units to mid-priced and entry-level buds. Qualcomm says its hybrid ANC feature allows for ambient noise leak-through that allows substantial but not total external noise suppression. That makes it easier for users to speak with others while wearing the buds or to more easily hear car horns or alarms.

Neustristor: The Computer Chip-Shaped Neutron Source

Posted by in categories: biotech/medical, computing

Sandia National Laboratories distinguished technical staff member Juan Elizondo-Decanini developed a new configuration for neutron generators by turning from conventional cylindrical tubes to the flat geometry of computer chips. The Neutristor is an ultra-compact, disposable, neutron generator 1000 times smaller than the closest competitor. The most practical application, and the most likely to be near-term, would be a tiny medical neutron source implanted close to a tumor that would allow cancer patients to receive a low neutron dose over a long period at home instead of having to be treated at a hospital. Elizondo-Decanini says the technology is ready to be licensed for some commercial applications, but other more complex commercial applications could take five to ten years.

Black holes: The ultimate quantum computers?

Posted by in categories: computing, cosmology, quantum physics

Circa 2006

By Maggie Mckee

Nearly all of the information that falls into a black hole escapes back out, a controversial new study argues. The work suggests that black holes could one day be used as incredibly accurate quantum computers – if enormous theoretical and practical hurdles can first be overcome.

Making sense of cells

Posted by in categories: biotech/medical, computing, food, mathematics, neuroscience

Our body’s ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround our cells, as well as our cells’ ability to ‘read’ these chemicals. Cells are highly sensitive. In fact, our immune system can be triggered by the presence of just one foreign molecule or ion. Yet researchers don’t know how cells achieve this level of sensitivity.

Now, scientists at the Biological Physics Theory Unit at Okinawa Institute of Science and Technology Graduate University (OIST) and collaborators at City University of New York have created a simple model that is providing some answers. They have used this model to determine which techniques a cell might employ to increase its sensitivity in different circumstances, shedding light on how the biochemical networks in our bodies operate.

“This model takes a complex biological system and abstracts it into a simple, understandable mathematical framework,” said Dr. Vudtiwat Ngampruetikorn, former postdoctoral researcher at OIST and the first author of the research paper, which was published in Nature Communications. “We can use it to tease apart how cells might choose to spend their energy budget, depending on the world around them and other cells they might be talking to.”

Samsung brings cutting-edge ultraviolet light technology to DRAM production

Posted by in categories: computing, electronics

Samsung Electronics today announced it will be introducing the first DRAM memory modules in the industry designed with cutting-edge Extreme Ultraviolet Technology (EUV).

One of the world’s leading memory manufacturers, Samsung says that response to a million evaluation units of its first line of 10nm-class DDR4 DRAM modules has been positive and that it will soon begin processing orders for worldwide distribution.

EUV technology allows memory modules to be manufactured more accurately and more quickly. It speeds up the lithography process by reducing the number of repetitive steps and facilitates the production of complex chip patterns. It means greater performance accuracy and a shortened development time.
