When a piece of gift-wrapping tape sticks to itself, it's frustrating, but when small parts in a microgear or micromotor stick together, an electronic device may not work well, if at all. Scientists now report that rough zinc oxide coatings can prevent tiny silicon parts from adhering to each other. The study could accelerate the development of even more advanced, high-performance electronics and small sensors.
Spider silk of fantastical, superhero strength is finally speeding toward commercial reality — at least a synthetic version of it is. The material, which is five times stronger than steel, could be used in products from bulletproof vests to medical implants, according to an article in Chemical & Engineering News (C&EN). C&EN is the weekly news magazine of the American Chemical Society.
We know that babies and young children often put non-food items in their mouths, a behaviour that occasionally leads to swallowing of foreign objects. Metallic toys and low-cost jewelry often contain toxic substances such as lead and cadmium. Do these objects present a health risk for young children?
With the explosive growth of bandwidth demand in telecommunications networks, experts are continually seeking new ways to transmit increasingly large amounts of data in the quickest and cheapest ways possible. Photonic devices—which convert light to electricity and vice versa—offer an energy-efficient alternative to traditional copper network links for information transmission.
Cells have a metabolism that can be altered according to its function and requirements. If cellular metabolism is disturbed, it can lead to disease of the entire organism. Researchers discovered that the uncoupling proteins UCP2 and UPC4 are involved in different types of cellular metabolism. The proteins provide information about the condition of cells. As a result, cell alterations can now be detected earlier than was thus far possible.
Last May, Axiom IC became part of Teledyne DALSA, adding our mixed signal CMOS design strength to the company's leadership in digital imaging solutions and semiconductor services. Our website now reflects that integration: you can find all our innovative design products and custom design services at http://teledynedalsa.com/semi/mixed-signal/.
Test Equipment Plus (LA Center, WA) announced the Signal Hound BB60A, a real-time spectrum analyzer and RF recorder designed to capture and display RF events as short as 1 µs. The BB60A is a small, lightweight, and affordable USB-based real-time RF spectrum analyzer....
In the fight against parasites, the Barberry sacrifices its own seeds depending upon its chances of survival. Plants are also able to make complex decisions. At least this is what scientists from the Helmholtz Center for Environmental Research (UFZ) and the University of Göttingen have concluded from their investigations on Barberry (Berberis vulgaris), which is able to abort its own seeds to prevent parasite infestation.
On March 2 and 3, a major winter storm brought snow to the mid-Atlantic, freezing rain to the Carolinas and rain and some freezing rain to the Gulf Coast states. Visible and infrared imagery over those two days captured by NOAA's GOES-East or GOES-13 satellite were compiled into a video made by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.
Research in the News: Children ineligible under new autism criteria will likely receive alternative diagnosisMarch 5, 2014 10:18 am | by Yale UniversityYale University | News | Comments
When a new diagnostic definition of autism spectrum disorders (ASD) went into effect in May 2013, many were concerned that fewer individuals would be diagnosed with ASD, and therefore not qualify for special services. But a new Yale study published in the Journal of the American Academy of Child...
Whenever you pass a license plate scanner, your whereabouts and personal information are likely being collected by the law enforcement agency of the state or municipality you’re in. Now, Washington is tipping its hand that it wants that information, too.
Being able to charge 30 electric cars at once requires ingenious energy management. Researchers are incorporating renewables into the design of a smart grid for Germany’s largest charging station. The network of charging stations for EVs is becoming more tightly meshed.
Following testing and preliminary acceptance in Europe in September 2013, MUSE was shipped to ESO's Paranal Observatory in Chile. It was reassembled at the base camp before being carefully transported to its new home at the VLT, where it is now installed on Unit Telescope 4. MUSE is the latest of the second generation instruments for the VLT (the first two were X-shooter and KMOS and the next, SPHERE, will follow shortly)
It's a bird, it's a plane, it's a CubeSat! With so many small, relatively inexpensive satellites deploying lately from the International Space Station, it may seem like the area referred to as low-Earth orbit, between 100 and 1,240 miles above the planet, is full of these compact cubes. The miniature satellites, or CubeSats, conduct research and demonstration missions.
An increasing number of unsecured, computer-guided production machinery and networks in production facilities are gradually evolving into gateways for data theft. New security technologies may directly shield the sensitive data that is kept there.
