Scientists have been exploring new ways to “smell” signs of cancer by analyzing what’s in patients’ breath. In Nano Letters, one team now reports new progress toward this goal. The researchers have developed a small array of flexible sensors, which accurately detect compounds in breath samples that are specific to ovarian cancer.
In the television drama “Mission Impossible,” instructions for the mission were delivered on an audio tape that destroyed itself immediately after being played. Should that series ever be revived, its producers might want to talk with Georgia Institute of Technology professor Andrei Fedorov about using his “disappearing circuits” to deliver the instructions.
HEMCO Corp.'s Universal is perfect for laboratories where space is limited or when multiple hoods are needed. Universal fume hoods are offered in 24-, 30-, 35- and 47-in widths. Hoods are designed for light to medium duty fume removal, and features sturdy dual wall construction and a fully vertical sliding sash. Dual walls reduce sound and vibration.
When European Space Agency astronaut Samantha Cristoforetti, NASA’s Terry Virts and Roscosmos commander Anton Shkaplerov returned to Earth following an extended period in space, helping hands greeted them upon exiting the landing module. Members of the ground crew carried the space travelers to a sitting area nearby the landing site.
Purdue Univ. has created a new lyophilization consortium, LyoHUB, to improve freeze-drying technology to make food, pharmaceuticals and biotech products safer and more affordable. The center is funded by NIST through a $453,623 planning grant from its Advanced Manufacturing Technology Consortia, or AMTech, program.
The Prior Scientific HLD117 series of linear stages for inverted research microscopes set new standards for convenience and top performance. The HLD117 linear stages operate on a different principle from conventional stepper motor, ball screw based motorized stages.
Researchers at Rice Univ. and Baylor College of Medicine have unlocked the structural details of a protein seen as key to treating a neuromuscular disease. Their success at obtaining a structural map of a protein known as leiomodin 2 (Lmod2) attached to two actin subunits offers a path forward for the study of nemaline myopathy, a hereditary disorder that weakens the muscles and can sometimes be fatal.
The way in which our cells convert food into fuel is shared by almost all living things and, now, scientists have discovered a likely reason why this is so widespread. Researchers examined how cells make energy from food, by digesting simple sugars such as glucose in a series of chemical reactions. This process is almost the same for every kind of cell, including animals, plants and bacteria.
Researchers have, for the first time, developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize. The work was tested successfully in an animal model.
Can portabella mushrooms stop cell phone batteries from degrading over time? Researchers at the Univ. of California, Riverside Bourns College of Engineering think so. They have created a new type of lithium-ion battery anode using portabella mushrooms, which are inexpensive, environmentally friendly and easy to produce.
Univ. of Delaware faculty from the College of Earth, Ocean, and Environment (CEOE), the College of Engineering and the Alfred Lerner School of Business and Economics say that the U.S. has fallen behind in offshore wind power.
Every Wednesday, R&D Magazine will feature a R&D 100 Flashback, chosen from our R&D 100 Awards archive of winners. This week’s flashback is Keithley Instruments’ Model 2657A High Power System SourceMeter SMU Instrument, which won the R&D 100 Award in 2013. The drive toward greater energy efficiency is creating increased demand for more efficient high-power semiconductor devices.
In the past 50 years, the western Antarctic Peninsula warmed over four times faster than the average rate of the Earth’s overall warming, according to the Antarctic and Southern Ocean Coalition. These temperature fluctuations, according to an international group of scientists, threaten species that thrive in frigid waters with negligible variation in seasonal sea temperatures.
A team of researchers in the Cockrell School of Engineering at The Univ. of Texas at Austin has invented a method for producing inexpensive and high-performing wearable patches that can continuously monitor the body’s vital signs for human health and performance tracking, potentially outperforming traditional monitoring tools such as cardiac event monitors.
On a July night, marine biologist David Gruber was scuba diving in the Solomon Islands, documenting corals and creatures known for their biofluorescence. Slime neon greens and subtle reds can be seen in video footage from National Geographic. Around 40 min into the dive, Gruber saw an unexpected entity glowing in the dark waters.
