Airbus and CFM International’s collaboration gave us the open fan engine that promises to reduce CO2 emissions.
A study of 29 European lakes has found that some naturally-occurring lake bacteria grow faster and more efficiently on the remains of plastic bags than on natural matter like leaves and twigs.
The bacteria break down the carbon compounds in plastic to use as food for their growth.
The scientists say that enriching waters with particular species of bacteria could be a natural way to remove plastic pollution from the environment.
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.
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.

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 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.
