Researchers have developed an automated blood drawing and testing device that provides rapid results and allows health care practitioners to spend more time treating patients.

The study, published in the journal TECHNOLOGY, suggests that the device provides highly accurate results from a white blood cell test, using a blood-like fluid spiked with fluorescent microbeads.

It includes an image-guided robot for drawing blood from veins, a sample-handling module and a centrifuge-based blood analyser, researchers said.

The testing used artificial arms with plastic tubes that served as blood vessels.

“This device represents the holy grail in blood testing technology,” said co-author Martin L. Yarmush from the Rutgers University-New Brunswick in New Jersey.

“Integrating miniaturised robotic and microfluidic (lab-on-a-chip) systems, this technology combines the breadth and accuracy of traditional blood drawing and laboratory testing with the speed and convenience of point-of-care testing,” Yarmush added.

According to researchers, diagnostic blood testing is the most commonly performed clinical procedure in the world, and it influences most of the medical decisions made in hospitals and laboratories.

But the success rate of manually drawing blood samples depends on clinicians’ skill and patient physiology and nearly all test results come from centralised labs that handle large numbers of samples and use labour-intensive analytical techniques, researchers added.

The device could provide rapid test results at bedsides or in ambulances, emergency rooms, clinics and doctors’ offices. (IANS)

Researchers ‘Extract’ Data From Junked Tesla Cars

The electric car maker was fairly quick to fix vulnerabilities exposed by white hat hackers

In a shocking revelation, security researchers have extracted personal and unencrypted data — videos, phonebooks, calendar items — of Tesla users from crashed models sold at junkyards and auctions.

According to a CNBC report, a security researcher who goes by the name GreenTheOnly extracted data from the computers in salvaged Tesla Model S, Model X and two Model 3 vehicles.

“The computers on Tesla vehicles keep everything that drivers have voluntarily stored on their cars, plus tons of other information generated by the vehicles, including video, location and navigational data showing exactly what happened leading up to a crash,” the report claimed on Friday, citing researchers.

A Tesla spokesperson told CNBC the company offers options that customers can use to protect personal data stored on their car. “It includes a factory reset option for deleting personal data and restoring customised settings to factory defaults, and a Valet Mode for hiding personal data (among other functions) when giving their keys to a valet,” the spokesperson was quoted as saying.

“We are committed to finding and improving upon the right balance between technical vehicle needs and the privacy of customers,” the Tesla spokesperson said.

According to the report, data stored on Tesla models is not automatically erased when the car is hauled away from an accident site or sold at auction.

GreenTheOnly and his fellow white-hat hacker “Theo” bought a wrecked Model 3 to evaluate the data that remains in the car’s computers after a crash. They extracted records that showed the car’s computers had stored data from at least 17 different devices.

“Mobile phones or tablets had paired to the car around 170 times. The Model 3 held 11 phonebooks’ worth of contact information from drivers or passengers who had paired their devices, and calendar entries with descriptions of planned appointments, and e-mail addresses of those invited,” the report said.
