Tiny pacemaker prototype avoids open chest surgery for infants

Tiny pacemaker prototype avoids open chest surgery for infants

Health
Nov. 9 (UPI) -- A pacemaker protype the size of an almond designed to make procedures for infants less invasive, less painful and more efficient has been tested on pigs. Dr. Rohan Kumthekar, a cardiology fellow at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children's National Medical Center in Washington, D.C., will show off the device and present his abstract Sunday at the American Heart Association's Scientific Sessions 2018 in Chicago. Kumthekar believes the process will lead to shorter surgeries, faster recovery times and reduced medical costs. "Placing a pacemaker in a small child is different than operating on an adult, due to their small chest cavity and narrow blood vessels," Kumthekar said in a press release. "By eliminating the need to cut through the sternu...

Tiny beetle gives clues for continental drift

Science
Oct. 31 (UPI) -- A small, ancient beetle might provide clues to how the Earth's landmass shifted, a study says. Researcher Shuhei Yamamoto believes a beetle trapped in piece of Burmese amber from 99 million years ago is the distant ancestor to insects found on the other side of the world today. He came upon this beetle in 2016, and now he thinks could provide more evidence for the theory of continental drift. "Like koalas and kangaroos today, certain animals that we think lived in Gondwanaland are only found in one part of the world. Although Propiestus went extinct long ago, our finding probably shows some amazing connections between Southern Hemisphere and Myanmar," Yamamoto said. "Our finding fits well with the hypothesis that, unlike today, Myanmar was once located in the Southern Hem...

China 'put tiny chips in US PCs to steal tech secrets'

Business
Tiny chips inserted in US computer equipment manufactured in China were used as part of a vast effort by Beijing to steal US technology secrets, according to Bloomberg. Apple and Amazon have distanced themselves from claims that they were among US companies targeted by the Chinese hackers.Bloomberg reported that the chips were inserted in computer motherboards manufactured in China for US-based supplier Super Micro Computer.It said dozens of large US firms and agencies were using the hardware - but Amazon first discovered the chips, the size of a grain of rice, during a security review it ordered after buying a software firm called Elemental three years ago.Bloomberg said the retail-to-cloud computing company alerted US authorities at the time, resulting in an inquiry and a...

Tiny X-ray beam reveals hidden photographs from the 19th century

Science
June 22 (UPI) -- Scientists have successfully recovered images from some of the earliest daguerreotypes, the silver plates used for one of the earliest forms of photography. To the naked eye, the portraits of a man and woman are unrecognizable. The daguerreotypes, taken as early as 1850, are too degraded by tarnish and wear. But researchers used rapid-scanning micro-X-ray fluorescence to see past the deterioration and recover the early images. "It's somewhat haunting because they are anonymous and yet it is striking at the same time," Madalena Kozachuk, a PhD student in the chemistry department at the University of Western Ontario, said in a news release. The images were analyzed at the National Gallery of Canada's photography research unit, where the daguerreotypes are stored. "The imag...
