A new study confutes the bold theory that T. rex was three separate species
Posted by Gemechu Taye in categories: biological, education
Back in March this year, a study published in Evolutionary Biology claimed that fossils categorized as Tyrannosaurus rex represent three separate species. However, a new study published on July 25 in Evolutionary Biology refutes this claim and suggests that the previous research lacked evidence and Tyrannosaurus rex is made of only one species.
The previously controversial research implied that T. rex should be reclassified as three different species, including the standard T. rex, the bulkier “T. imperator,” and the slimmer “T. regina.” Researchers analyzed 38 T. rex fossils that contained leg bones and teeth samples, a press release revealed.
However, paleontologists at the American Museum of Natural History and Carthage College were determined to review the data of the previous research, adding data points from 112 species of living dinosaurs—birds—and from four non-avian theropod dinosaurs.

PIP-II transportation test frame is ready for action
Posted by Shubham Ghosh Roy in categories: particle physics, transportation
Successful assembly was the result of a collaboration among three institutions in three countries.
Cryomodules are essential components for the U.S. Department of Energy’s Fermi National Accelerator Laboratory’s accelerator complex upgrade, known as the Proton Improvement Plan II, or PIP-II.
PIP-II features a brand-new, 800-million-electronvolt leading-edge superconducting radio-frequency linear accelerator, or linac for short, that will enable Fermilab to produce more than 1 megawatt of beam power, 60% higher than current capabilities. To achieve this groundbreaking feat, the linac will be made up of cryomodules, which are vessels containing niobium cavities.

Enhancing the safety of autonomous vehicles in critical scenarios
Posted by Wise Technology in categories: robotics/AI, transportation
Researchers at Ulm University in Germany have recently developed a new framework that could help to make self-driving cars safer in urban and highly dynamic environments. This framework, presented in a paper pre-published on arXiv, is designed to identify potential threats around the vehicle in real-time.
The team’s paper builds on one of their previous studies, featured in IEEE Transactions on Intelligent Vehicles earlier this year. This previous work was aimed at providing autonomous vehicles with situation-aware environment perception capabilities, thus making them more responsive in complex and dynamic unknown environments.
“The core idea behind our work is to allocate perception resources only to areas around an automated vehicle that are relevant in its current situation (e.g., its current driving task) instead of the naive 360° perception field,” Matti Henning, one of the researchers who carried out the study, told TechXplore. “In this way, computational resources can be saved to increase the efficiency of automated vehicles.”

Samsung begins shipping world’s first 3nm chips
Posted by Wise Technology in category: computing
Samsung has started shipping the world’s first 3-nanometer (nm) chips from its chip-making complex in Hwaseong, South Korea’s Gyeonggi Province, the tech giant revealed on Monday at a ceremony to celebrate the shipment.
The company said its first-generation 3nm process has reduced power consumption by 45 percent and improved performance by 23 percent using gate-all-around (GAA) process, compared to the current 5nm chips using fin field-effect transistor technology (FinFET).
According to Samsung, its engineers started researching on GAA transistors in the early 2000s and went on to experiment with the design from 2017. Last month, the company became the first chipmaker to begin mass production of the 3nm chips.

Hackers can turn computer cables into antenna to steal sensitive data
Posted by Shubham Ghosh Roy in categories: computing, internet
Computers are sometimes kept disconnected from the internet, or “air gapped”, to avoid remote hackers gaining access to steal data, but now there is a way to use a hard drive cable to transmit information via radio waves.

Chinese scientists invent laser so powerful it can write words in mid-air
Posted by Jose Ruben Rodriguez Fuentes in category: futurism
Scientists in China have invented a powerful laser which can essentially scorch the air to create patterns. Lasers have already been used to create optical illusions, but they needed dust or clouds as a medium.
The Wuhan-based team demonstrated the laser by writing Chinese characters in the air, which can be viewed and even touched.

Raspberry Pi Zero 2 W Lego-Powered Submarine Makes a Splash
Posted by Jose Ruben Rodriguez Fuentes in categories: drones, electronics
BEC was kind enough to share a parts list of everything used to create this project. It’s operated primarily by a Raspberry Pi Zero 2 W, with most components housed neatly inside an acrylic cylinder. It’s driven by a drone propeller alongside a couple of Pololu 2,130 DRV8833 Dual H-bridge motor drivers. The sensors include both a pressure sensor and a distance sensor, while a Lego Rechargeable 9V Battery Box supplies the power with the assistance of a Pololu 2,123 S7V8F5 5V voltage regulator.
The Raspberry Pi runs Raspberry Pi OS, while the code used to operate the submarine functions is handled using a custom Python script. BEC explains that Thonny was used to run the Python code, which is open-source and available for anyone to explore.
