The neural basis of affect sharing is not fully understood. Here, the authors show that the anterior cingulate cortex (ACC) stably recruits neural ensembles encoding observational fear, specifically represented by affective responses to pain experience.
2/27/25 | 720 CT Intuitive Machines’ IM-2 Lunar Lander Successfully Commissioned and En Route to the Moon:
After liftoff on February 26, Athena established a stable attitude, solar charging, and radio communications contact with our mission operations center in Houston. The lander is in excellent health, sending selfies and preparing for a series of main engine firings to refine her trajectory ahead of lunar orbit insertion, planned on March 3. Intuitive Machines is targeting a lunar landing opportunity on March 6.
With Google’s latest AI model, Gemini 2.0, launched in December, the company is making big moves in AI. Brin’s message is clear, the race to AGI is on, and Google plans to win it.
Long Ju, the lead researcher, describes the new material, rhombohedral pentalayer graphene, as a gold mine, with discoveries revealed at every step.
A novel class of quantum particles behaves in unexpected ways
Rhombohedral pentalayer graphene is a unique form of pencil lead. Pencil lead, or graphite, consists of graphene, a single layer of carbon atoms arranged in a hexagonal pattern. Rhombohedral pentalayer graphene has five layers of graphene stacked in a specific order.

Indeed calculates the index change in seasonally-adjusted job postings since February 1, 2020, the pre-pandemic baseline. Indeed seasonally adjusts each series based on historical patterns in 2017, 2018, and 2019. Each series, including the national trend, occupational sectors, and sub-national geographies, is seasonally adjusted separately. Indeed switched to this new methodology in December 2022 and now reports all historical data using this new methodology. Historical numbers have been revised and may differ significantly from originally reported values. The new methodology applies a detrended seasonal adjustment factor to the index change in job postings. For more information, see Frequently Asked Questions regarding Indeed Data.

In a new study published in Physical Review Letters, scientists have discovered a novel approach to detecting the quantum properties of a system by simply using heat as a witness, requiring no direct measurement of the quantum system itself.
The study proposes connecting thermodynamics with quantum information theory, drawing inspiration from the concept of Maxwell’s demon.
The concept proposed in the 19th century involves an imaginary entity, Maxwell’s demon, that can sort gas molecules by their velocities inside a closed box, seemingly violating the second law of thermodynamics.
The northern lowlands of early Mars could have contained a significant quantity of liquid water. However, the ocean hypothesis remains controversial due to the lack of conclusive evidence from the Martian subsurface. We use data from the Zhurong Rover Penetrating Radar on the southern Utopia Planitia to identify subsurface dipping reflectors indicative of an ancient prograding shoreline. The reflectors dip unidirectionally with inclinations in the range 6° to 20° and are imaged to a thickness of 10 to 35 m along an uninterrupted 1.3 km northward shoreline-perpendicular traverse. The consistent dip inclinations, absence of dissection by fluvial channels along the extended traverse, and low permittivity of the sediments are consistent with terrestrial coastal deposits—and discount fluvial, aeolian, or magmatic origins favored elsewhere on Mars.

I just saw “Companion” which is set in a world about 20 years in the future and it was the first movie in quite a while that had a solid plot. I find most movies pretty frustrating as they focus on special effects instead of a coherent plot.
The less you know before you see the movie, the better. Avoiding the trailer is recommended.
Companion: Directed by Drew Hancock. With Sophie Thatcher, Jack Quaid, Lukas Gage, Megan Suri. A weekend getaway with friends at a remote cabin turns into chaos after it’s revealed that one of the guests is not what they seem.
