Targeted repairs with ‘nicks’ of single DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

People who have at least two of the conditions type 2 diabetes, heart disease, or stroke are twice as likely to develop dementia. Research from Sweden’s Karolinska Institutet that was published in the journal Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

US Rep Jason Crow, of the US House Intelligence Committee, warned that bio-weapons are being made that use a target’s DNA to only kill that person at a security forum on Friday.

Counter-drone systems typically attack a UAV’s radio control or GPS systems, disabling pilot control as well as pre-programmed missions. But British defense tech company QinetiQ has now demonstrated a laser-controlled drone these systems can’t stop.

Microsoft has chosen to add specific security measures against brute force attacks against RDP (Remote Desktop Protocol). These security improvements have been introduced in the most recent builds of Windows 11. Given the evolution of this type of attack abusing RDP, Microsoft decided to add the security measure in the latest Insider Preview22528.1000. This system automatically locks accounts for 10 minutes after 10 invalid login attempts. The news was broken by David Weston (VP of OS & Enterprise Security) on Twitter last week.

These kinds of attacks against RDP are quite common in human operated ransomware. With this relatively simple measure, it is possible to complicate brute force attacks, being quite effective in discouraging them. However, it was already possible to activate this measure in Windows 10, so the novelty is really enabling it by default.

A new batch of malicious Android apps filled with adware and malware was found on the Google Play Store that have been installed close to 10 million times on mobile devices.

The apps pose as image-editing tools, virtual keyboards, system optimizers, wallpaper changers, and more. However, their underlying functionality is to push intrusive ads, subscribe users to premium services, and steal victims’ social media accounts.

The discovery of these malicious apps comes from the Dr. Web antivirus team, who highlighted the new threats in a report published today.

New research from Binghamton University, State University of New York offers a second life for CDs: Turn them into flexible biosensors that are inexpensive and easy to manufacture.

In a paper published this month in Nature Communications, Matthew Brown, Ph.D. ‘22, and Assistant Professor Ahyeon Koh from the Department of Biomedical Engineering show how a gold CD’s thin metallic layer can be separated from the rigid plastic and fashioned into sensors to monitor electrical activity in human hearts and muscles as well as lactate, glucose, pH and oxygen levels. The sensors can communicate with a smartphone via Bluetooth.

The fabrication is completed in 20 to 30 minutes without releasing toxic chemicals or needing expensive equipment, and it costs about $1.50 per device. According to the paper, “this sustainable approach for upcycling electronic waste provides an advantageous research-based waste stream that does not require cutting-edge microfabrication facilities, expensive materials or high-caliber engineering skills.”
