Leica Microsystems has introduced the Leica HyD SMD universal hybrid photodetector with characteristics for single-molecule detection, which allows precise measurement of concentration and observation of fast cellular processes. The photodetector combines the characteristics of a classic photomultiplier tube with highly sensitive avalanche photodiodes.
JM Science offers a selection of deuterium lamps (D2 lamps) for Shimadzu, Agilent, Waters, Thermo Fisher, Jasco and Hitachi instruments. The lamps are designed for atomic absorption, ultraviolet visible spectrophotometer and high-performance liquid chromatography instrumentation.
Univ. of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light. Polarizers are indispensable in digital photography and LCD displays, but they block enormous amounts of light, wasting energy and making it more difficult to photograph in low light.
Engineers have created a new way to use lidar technology to identify and classify landslides on a landscape scale, which may revolutionize the understanding of landslides in the U.S. and reveal them to be far more common and hazardous than often understood. The new, non-subjective technology can analyze and classify the landslide risk in an area of 50 or more square miles in about 30 mins.
Flexible electronic sensors based on paper have the potential to cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper.
New research has found that one of the world's most prolific bacteria manages to afflict humans, animals and even plants by way of a mechanism not before seen in any infectious microorganism—a sense of touch. This unique ability helps make the bacteria Pseudomonas aeruginosa ubiquitous, but it also might leave these antibiotic-resistant organisms vulnerable to a new form of treatment.
A widely presumed problem of aging is that the brain becomes less flexible or plastic, and that learning may therefore become more difficult. A new study led by Brown Univ. researchers contradicts that notion with a finding that plasticity did occur in seniors who learned a task well, but it occurred in a different part of the brain than in younger people.
Argonne National Laboratory has announced a new intellectual property licensing agreement with AKHAN Semiconductor, continuing a productive public-private partnership that will bring diamond-based semiconductor technologies to market. The agreement gives AKHAN exclusive rights to a suite of breakthrough diamond-based semiconductor inventions developed by nanoscientist Ani Sumant of Argonne’s Center for Nanoscale Materials.
As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it. Scientists know the other varieties exist because when they synthesize these amino acids and sugars in a laboratory, roughly equal numbers of left- and right-facing arrangements form.
Now that car makers have demonstrated through hybrid vehicle success that consumers want less-polluting tailpipes, they are shifting even greener. In 2015, Toyota will roll out the first hydrogen fuel-cell car for personal use that emits only water. An article in Chemical & Engineering Newsexplains how hydrogen could supplant hybrid and electric car technology.
Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways to hide objects from view. The latest effort, developed at the Univ. of Rochester, not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration.
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space microphones. Researchers at Cardiff Univ. are trying to work out the possible sounds scientists might expect to hear when the ultra-sensitive LIGO and Virgo detectors are switched on in 2015.
The government proposed new rules Wednesday to make it easier for doctors and patients to learn if clinical trials of treatments worked or not. Thousands of Americans participate in clinical trials every year, testing new treatments, comparing old ones or helping to uncover general knowledge about health. Many of the studies are reported in scientific journals and trumpeted in the news.
Carpe diem…seize the day. This Latin phrase, coined by the Roman poet Horace in 23 BC, is used often to encourage us to take full advantage of the opportunities each day provides. In modern times with seemingly limitless amounts of data on any conceivable subject available at our fingertips, organizations globally are developing strategies to leverage this growing data volume to enhance business success.
Additive manufacturing, widely known as 3-D printing, offers many advantages over traditional manufacturing methods such as injection molding and machining, which limit a part’s geometry and size. By freeing manufacturers from these design constraints, additive manufacturing helps create complex parts that spark innovation and save companies time and money.
