What is an aurora, and why do they come in different shapes and colors?

Posted by in category: particle physics

Over millennia, humans have observed and been inspired by beautiful displays of light bands dancing across dark night skies. Today, we call these lights the aurora: the aurora borealis in the northern hemisphere, and the aurora australis in the southern hemisphere.

Nowadays, we understand aurorae are caused by charged particles from Earth’s magnetosphere and the solar wind colliding with other particles in Earth’s upper atmosphere. Those collisions excite the atmospheric particles, which then release light as they “relax” back to their unexcited state.

Hacking group targets file transfer tool, leading to major data breaches, government warns

Posted by in categories: cybercrime/malcode, government

A hacking group believed to be behind a cybercrime spree in 2021 is once again involved in an active hacking campaign targeting a file transfer tool that could lead to a wave of data breaches, according to US cybersecurity officials.

The hacking group, named “CL0P,” is targeting a file transfer tool called MOVEit that belongs to Progress Software Corp., according to a joint advisory by the Cybersecurity and Infrastructure Security Agency and FBI on June 7.

Officials say CL0P has been attempting to steal data belonging to MOVEit clients since at least May 27. A confirmed victim includes Zellis, a UK-based payroll services provider whose clients include British Airways and the BBC, reports Law360.

Black phosphorus–based human–machine communication interface: A breakthrough in assistive technology

Posted by in categories: chemistry, cyborgs

Researchers at the University of Chemistry and Technology in Prague have made progress in the field of assistive technology with the development of a novel auditory human–machine interface using black phosphorus–based tactile sensors. Research led by Prof. Martin Pumera and Dr. Jan Vyskočil has the potential to revolutionize communication for visually or speech-disabled individuals by providing an intuitive and efficient means of conveying information.

Assistive technology that utilizes has traditionally been employed by individuals with or speech and language difficulties. In this study, the focus was on creating an auditory that utilizes audio as a platform for communication between disabled users and society. The researchers developed a piezoresistive tactile sensor using a composite of black phosphorus and polyaniline (BP@PANI) through a simple chemical oxidative polymerization process on cotton fabric.

The unique structure and superior electrical properties of black phosphorus, combined with the large surface area of the fabric, enabled the BP@PANI-based tactile sensor to exhibit exceptional sensitivity, low-pressure sensitivity, reasonable response time, and excellent cycle stability. To demonstrate the real-world application, a was created, incorporating six BP@PANI corresponding to braille characters. This device can convert pressed text into audio, aiding visually or speech-disabled individuals in reading and typing. It offers a promising solution for improving communication and accessibility for this demographic.

Former Samsung exec accused of stealing data to build copycat chip plant in China

Posted by in categories: computing, electronics

A former executive of Samsung Electronics stole the juggernaut’s confidential semiconductor data to build a copycat chip facility in China, South Korean prosecutors alleged on Monday.

The 65-year-old defendant, who also previously worked for Korean chipmaker SK Hynix, has been arrested. He has been accused of violating industrial technology protection laws and stealing trade secrets from 2018 to 2019 to establish a copy of Samsung’s semiconductor plant, just 1.5 kilometers away from Samsung chip factory in Xi’an, China.

The ex-Samsung exec’s attempt to build the copycat chip plant allegedly fell through after his backer, purportedly an undisclosed Taiwanese company, canceled more than a $6 billion (approximately 8 trillion won) investment into the project, prosecutors said. Instead, he received capital from investors in China and Taiwan to produce trial chip products based on Samsung’s technology.

New scientific findings reveal neuroinflammation as key factor in alcohol-induced pain

Posted by in category: neuroscience

Researchers at Scripps Research have discovered that chronic alcohol consumption can increase sensitivity to pain through two distinct molecular mechanisms: one related to alcohol intake and the other to alcohol withdrawal. This finding, published in the British Journal of Pharmacology, sheds light on the intricate relationship between alcohol and pain.

The researchers sought to better understand the relationship between chronic pain and alcohol use disorder. They wanted to investigate the underlying causes of different types of alcohol-related pain, such as alcoholic neuropathy and allodynia, and how they develop at the spinal cord level. The researchers aimed to examine the role of microglia, immune cells in the central nervous system, in the development of chronic alcohol-induced allodynia and neuropathy.

Alcoholic neuropathy refers to nerve damage caused by long-term excessive alcohol consumption. It is a type of peripheral neuropathy that affects the peripheral nerves, which are responsible for transmitting signals between the brain, spinal cord, and the rest of the body.
