Even simple motions make ripples across brain, study finds
Posted by Shubham Ghosh Roy in category: neuroscience
Even a simple movement like pushing a button sends ripples of activity throughout networks of neurons spanning across the brain, new University of Oregon research shows.
The finding highlights just how complex the human brain is, challenging the simplified textbook picture of distinct brain areas dedicated to specific functions.
โItโs really well known that that the primary motor cortex controls movement output,โ said Alex Rockhill, a graduate student in the lab of human physiology professor Nicki Swann. โBut thereโs a lot more to movement than this one brain area.โ

AIโs Future: The Role of Prompt Engineering
Posted by Shubham Ghosh Roy in categories: internet, robotics/AI
โThe future of AI is much bigger than anyone realizes โ not just in terms of technology, but in its impact on society as a whole.โ โ Mark Zuckerberg
Prompt engineering is a process of crafting optimized input texts (prompts) to generate accurate results from the artificial intelligence model. By the launch of ChatGPT, prompt engineering is the booming term in internet. Actually what is its deep meaning and is it be the future of AI. Prompt engineering is a relatively new field that focuses on the design and development of systems that can generate human-like prompts, such as text, speech, and images. These prompts can be used to interact with users in a more natural and intuitive way, making it easier for them to understand and use AI-powered systems.
By the advance of artificial intelligence models like ChatGPT, midjourney and stable diffusion which are enriched with high potential people are confused how to use it and what are the optimized prompts that could be used to extract the full potential of these models. One key aspect of prompt engineering is data preprocessing and preparation. This includes cleaning, normalizing, and formatting the data used to train the model, so that it is in the right format and of high quality.

After Google Docs, hackers turn to Microsoft OneNote to target users with malware
Posted by Shubham Ghosh Roy in categories: cybercrime/malcode, finance
Cyber attackers around the world are looking at alternate file attachment types to trap users with phishing and malware attacks, according to a report by Bleeping Computer. The alternate attachment types come in the form of online, open-source file attachments, and the latest type that has now been spotted includes Microsoft OneNote files. According to the report, hackers are exploiting OneNote attachments in emails to trick users into downloading malware.
The report stated that hackers switched to OneNote, Microsoftโs online note-taking alternative to Word, after the company disabled โmacrosโ by default in email attachments. The latter, which refer to code snippets that execute a command upon a user opening the email attachment, were long since used by attackers to get users to download malware attachments.
By using macros, hackers would store malware within Microsoft Word or Excel documents. Once a user opened the attachment, the malware would get triggered automatically. These malware, in turn, could be used for a wide range of attacks โ including remote code execution, botnets, financial or identity theft, or even spyware.

Where Is Tech Going in 2023?
Posted by Shubham Ghosh Roy in categories: business, robotics/AI, security
A group of McKinseyโs technology practice leaders have taken a look at what 2023 might hold, and offer a few new yearโs tech resolutions to consider: 1) Look for combinatorial trends, in which the sum impact of new technologies create new opportunities. 2) Prep boards for tipping point technologies. 3) Relieve the bureaucratic burden on your engineers to increase their productivity. 4) Look for new opportunities in the cloud. 5) Take advantage of how the cloud is changing security. 6) Take advantage of decentralized AI capabilities โ and what this technology might mean for your business model.

NASA successfully tests new engine for deep space exploration
Posted by Alberto Lao in category: space travel
NASA announced that its engineers have developed and tested the agencyโs first full-scale rotating detonation rocket engine (RDRE).
The agency said that the design could significantly change how future propulsion systems are built. The supersonic rocket engine uses detonation, with the design producing more power while using less fuel than todayโs propulsion systems.
It has the potential to power both human landers and interplanetary vehicles to deep space destinations, like the moon or Mars.

โExtraordinaryโ video shows asteroid passing โextremelyโ close to Earth
Posted by Genevieve Klien in categories: asteroid/comet impacts, existential risks
An astronomer has captured โextraordinaryโ footage of an asteroid that made an โextremely closeโ approach to the Earth on Thursday.
The space rock, known as 2023 BU, zoomed over the southern tip of South America yesterday, while it was only around 2,200 miles above the surface of the Earth.
This is one of the closest approaches of an near-Earth object ever recorded. Data from NASAโs Center for Near Earth Object Studies showed that the flyby of 2023 BU was the fourth-nearest of more than 35,000 past and future Earth close approaches in the 300-year period from 1900 to 2200.

I Edited Human DNA at Home With a DIY CRISPR Kit
Posted by Shubham Ghosh Roy in categories: bioengineering, biotech/medical, genetics
I never thought Iโd order live human kidney cells to my address, but that all changed when I found out about biohacker Jo Zaynerโs at-home genetic engineering class.
You may know Jo Zayner, a โbiohackerโ who has been in the vanguard of scientific self-experimentation for years, from their role in Netflixโs 2019 docuseries Unnatural Selection. The series shows Zayner attempting to edit their DNA by injecting themselves with CRISPR, a gene-editing technology. The action inspired a firestorm of criticism.
Zayner is also known for a variety of other bold moves, such as claiming to create a DIY at-home COVID vaccine in 2020 and executing their own fecal microbiome transplant.

Elon Musk kills hope of Tesla retrofitting new Autopilot/Self-Driving hardware
Posted by Kelvin Dafiaghor in categories: Elon Musk, robotics/AI, transportation
Elon Musk has killed the little hope some had for Tesla in offering a retrofit to the new Autopilot/Self-Driving hardware (HW4) to current Tesla owners.
Tesla is expected to announce a new Autopilot/Self-Driving hardware suite, which has been referred to as Hardware 4.0 (HW4), any day now.
There have been quite a few indications that some major changes are coming. For example, after famously removing radar sensors from its hardware suite, we learned in December that Tesla is planning to add one as soon as this month.
