The two new studies place the sources of ordinary chondrite types into specific asteroid families – and most likely specific asteroids. This work requires painstaking back-tracking of meteoroid trajectories, observations of individual asteroids, and detailed modelling of the orbital evolution of parent bodies.

The study led by Miroslav Brož reports that ordinary chondrites originate from collisions between asteroids larger than 30 kilometres in diameter that occurred less than 30 million years ago.

The Koronis and Massalia asteroid families provide appropriate body sizes and are in a position that leads to material falling to Earth, based on detailed computer modelling. Of these families, asteroids Koronis and Karin are likely the dominant sources of H chondrites. Massalia (L) and Flora (LL) families are by far the main sources of L-and LL-like meteorites.

A security flaw impacting the Wi-Fi Test Suite could enable unauthenticated local attackers to execute arbitrary code with elevated privileges.

The CERT Coordination Center (CERT/CC) said the vulnerability, tracked as CVE-2024–41992, said the susceptible code from the Wi-Fi Alliance has been found deployed on Arcadyan FMIMG51AX000J routers.

“This flaw allows an unauthenticated local attacker to exploit the Wi-Fi Test Suite by sending specially crafted packets, enabling the execution of arbitrary commands with root privileges on the affected routers,” the CERT/CC said in an advisory released Wednesday.

Over the past decade or so, computer scientists have developed increasingly advanced computational techniques that can tackle real-world tasks with human-comparable accuracy. While many of these artificial intelligence (AI) models have achieved remarkable results, they often do not precisely replicate the computations performed by the human brain.

Researchers at Tibbling Technologies, Broad Institute at Harvard Medical School, The Australian National University and other institutes recently tried to use AI to mimic a specific type of computation performed by circuits in the neocortex, known as “winner-take-all” computations.

Their paper, published on the bioRxiv preprint server, reports the successful emulation of this computation and shows that adding it to transformer-based models could significantly improve their performance on image classification tasks.

December is shaping up to be a month of dueling AI announcements from OpenAI and Google.

With no conclusive laboratory results, researchers are turning to other methods to find the elusive substance.

A research team led by Professor Bonghoon Kim from DGIST’s Department of Robotics and Mechatronics Engineering has developed a “3D smart energy device” that features both reversible heating and cooling capabilities. Their device was recognized for its excellence and practicality through its selection as the cover article of the international journal Advanced Materials.

The team collaborated with Professor Bongjae Lee from KAIST’s Department of Mechanical Engineering and Professor Heon Lee from Korea University’s Department of Materials Science and Engineering.

Heating and cooling account for approximately 50% of the global energy consumption, contributing significantly to environmental problems such as global warming and air pollution. In response, solar absorption and radiative cooling devices, which harness the sun and outdoor air as heat and cold sources, are gaining attention as eco-friendly and sustainable solutions.
