Small, convenient mosquito repellent device passes test to protect military personnel

Posted by in categories: food, military

A device developed at the University of Florida for the U.S. military provides protection from mosquitos for an extended period and requires no heat, electricity or skin contact.

The controlled-release passive device was designed by Nagarajan Rajagopal, a Ph.D. candidate and Dr. Christopher Batich in UF’s Department of Materials Science and Engineering in the Herbert Wertheim College of Engineering. It recently was tested successfully in a four-week semi-field study at the U.S. Department of Agriculture in Gainesville in a collaboration with Dr. Daniel Kline, Dr. Jerry Hogsette and Adam Bowman from the USDA’s Center for Medical, Agricultural and Veterinary Entomology.

Results showed the controlled release of the repellent transfluthrin was effective in preventing multiple species of mosquitos from entering the testing site. Transfluthrin is an organic insecticide considered to be safe for humans and animals.

Experts Uncover the Identity of Mastermind Behind Golden Chickens Malware Service

Posted by in category: cybercrime/malcode

Cybersecurity researchers have discovered the real-world identity of the threat actor behind Golden Chickens malware-as-a-service, who goes by the online persona “badbullzvenom.”

ESentire’s Threat Response Unit (TRU), in an exhaustive report published following a 16-month-long investigation, said it “found multiple mentions of the badbullzvenom account being shared between two people.”

The second threat actor, known as Frapstar, is said to identify themselves as “Chuck from Montreal,” enabling the cybersecurity firm to piece together the criminal actor’s digital footprint.

Researchers Discover New PlugX Malware Variant Spreading via Removable USB Devices

Posted by in category: cybercrime/malcode

Cybersecurity researchers have uncovered a PlugX sample that employs sneaky methods to infect attached removable USB media devices in order to propagate the malware to additional systems.

“This PlugX variant is wormable and infects USB devices in such a way that it conceals itself from the Windows operating file system,” Palo Alto Networks Unit 42 researchers Mike Harbison and Jen Miller-Osborn said. “A user would not know their USB device is infected or possibly used to exfiltrate data out of their networks.”

The cybersecurity company said it uncovered the artifact during an incident response effort following a Black Basta ransomware attack against an unnamed victim. Among other tools discovered in the compromised environment include the Gootkit malware loader and the Brute Ratel C4 red team framework.

Starling Medical’s new urine-testing device turns your toilet into a health tracker

Posted by in categories: biotech/medical, health

If you enjoy some good toilet technology, then I think “urine” for a treat. Starling Medical is poised to launch its at-home urine diagnostic patient-monitoring platform, dubbed “StarStream,” that doesn’t rely on the traditional catching containers or dipsticks.

Now, if you’re thinking this technology sounds familiar, you would be correct: My colleague Haje Jan Kamps wrote about Withings’ U-Scan, a urinalysis device, earlier this month when the health-focused consumer tech company debuted it at CES. U-Scan also sits in the toilet for at-home monitoring.

However, Alex Arevalos, Starling’s co-founder and CEO, told TechCrunch that this is an underserved market — the global urinalysis market is forecasted to be valued at $4.9 billion by 2026, meaning there is plenty of room for Withings and a scrappy startup.

These record-breaking twins were born from 30-year-old frozen embryos. Their mom is only 3 years older than that

Posted by in category: biotech/medical

Three of them were transferred, and two developed. Rachel, who said she had a relatively straightforward pregnancy, gave birth on October 31 at 37 weeks and two days.

Timothy weighed 6 pounds and 7 ounces. Lydia weighed 5 pounds and 11 ounces.

The twins’ record-breaking delivery was verified by the University of Tennessee’s Preston Medical Library. The previous record holder was a child named Molly Gibson, who was born in 2017. The frozen embryo that later became Molly had been stored for 24 years.

Special Vascular Cells Adjust Blood Flow in Brain Capillaries Based on Local Energy Needs

Posted by in categories: biotech/medical, neuroscience

Its impressive how adaptive the brain is to each situation. It can sense which portions of the brain need more blood flow depending on energy usage and makes the needed tiny adjustments.

Summary: Researchers identified a specific type of cell that sits on top of the brain’s smallest blood vessels that sense when their region of the brain is in need of energy.
