Mice with glowing hearts shed light on how hearts develop

... per second, imaging requires a special high-speed camera that is cooled to minus 90 degrees Celsius (minus 128 Fahrenheit), reducing "noise" for a sharper image. Co-author Guy Salama of the University of Pittsburgh contributed the optical imaging work. Using this technique, the researchers were able to ...

New crop of technology reveals plant health

...stem," she continues. The system uses an infrared camera to scan the entire crop canopy. It can automatically detect when individual or groups of plants are getting too hot. Another sensor detects chlorophyll fluorescence, which tells the system the rate at which the plant is absorbing energy. That reflect...

Purdue creates new low-cost system to detect bacteria

..."light-scatter pattern" is recorded with a digital camera and analyzed with sophisticated software to identify the types of bacteria growing in colonies. "There are potentially thousands of applications for this new technology, from identifying stem cells to drug-resistant staph infections to pathogens on...

Drug discovery team to explore newly discovered deep-sea reefs

...ay of sponges, corals, fish, and other animals. A camera developed at the University of Miami allowed researchers to get an enticing glimpse of the bottom, but until researchers make it to the seafloor in the submersible they will not be able to determine the extent and biological diversity of the newly di...

New light microscope sharpens scientists' focus

... go into each PALM picture is cumbersome. With the camera snapping one to two pictures each second, it can take two to 12 hours to image a single sample. Activating more molecules per frame would reduce the number images that must be collected, and making the molecules brighter would reduce the time needed ...

Even when faint, ovary scent draws sperm cells

...solution. The researchers affixed a microscope and camera to the device and then recorded video of the sperm during assays. "We combined in a microfluidic device the ability to generate a chemical gradient with transporting sperm cells to evaluate sperm chemotaxis," Jacobson said. "The use of microfluidic...

Nanosecond-scale release of stinging jellyfish nematocysts

...tocyst discharge with an electronic framing-streak camera at a framing rate of 1,430,000 frames per second. They show discharge kinetics of nematocysts in Hydra to be as short as 700 nanoseconds, creating an acceleration of up to 5,410,000 g. The researchers calculate that although the accelerated mass is v...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

The new technologically advanced D-SPECT camera enables shorter image acquisition times, provides ...nn. "In addition, as the speed of this new D-SPECT camera approaches the imaging speed of computed tomography (CT), it will become economical to have function...

Robots manipulating animal behaviour

...tery, several computer processors, a light-sensing camera and an array of infrared proximity sensors. When dropped into a small experimental area with a maze of curved walls, the robots move, turn and stop. They can navigate their way safely by avoiding the walls, obstacles or each other, follow the walls...

High dopamine transporter levels not correlated with ADHD

...ositron emission tomography (PET) scanner. The PET camera picks up the radioactive signal from the tracer to precisely measure the level of dopamine transporters. The PET scans revealed that ADHD subjects had significantly fewer dopamine transporters than control subjects in the nucleus accumbens, an area...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

...under water." Catania mounted a high-speed video camera so that it pointed up through the bottom of a glass tank. Then he stuck various objects on the bottom of the tank ?pieces of earthworm, small fish, insect cuticle and blobs of wax and silicon ?and observed the moles' behavior. He saw that, when the m...

Extraordinary life found around deep-sea gas seeps

...he scientists then lowered a towed video and still camera system over each site to identify seep organisms and the extent of the seafloor they covered. With the live video feed, the scientists observed 30?0 cm long tube worms emerging from beneath limestone boulders and slabs lying at the core of the see...

Telemedicine robots help improve health

... on the robot's television–like screen. A built-in camera and microphone enables the specialist to see and speak with the child. Eliza is one of four robots that will be commissioned over the next three years, thanks to a $335,000 grant provided by mining company Xstrata (Community Partnership Program),...

New system could drastically reduce herbicide use

... the machine, "we're going to try and use only the camera vision for navigation," said Jeon, "which makes it a lot more difficult." The robot stands a little more than two feet tall, is 28 inches wide and almost five feet long. He can travel about three miles per hour and moves on wheels, although the re...
