In the quest to uncover the fundamental particles and forces of nature, one of the critical challenges facing high-energy experiments at the Large Hadron Collider (LHC) is ensuring the quality of the vast amounts of data collected. To do this, data quality monitoring systems are in place for the various subdetectors of an experiment and they play an important role in checking the accuracy of the data.
Summary: A recent study offers new insights into how brain regions coordinate during rest, using resting-state fMRI (rsfMRI) and neural recordings in mice. By comparing blood flow patterns with direct neural activity, researchers found that some brain activity remains “invisible” in traditional rsfMRI scans. This hidden activity suggests that current brain imaging techniques may miss key elements of neural behavior.
The findings, potentially applicable to human studies, may refine our understanding of brain networks. Further research could improve the accuracy of interpreting brain activity.

This study explores how muscle contractions, such as those that occur during exercise, influence motor neurons—the cells responsible for controlling muscle movement.
There’s no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system.
Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that when muscles contract during exercise, they release a soup of biochemical signals called myokines.
In the presence of these muscle-generated signals, neurons grew four times further compared to neurons that were not exposed to myokines. These cellular-level experiments suggest that exercise can have a significant biochemical effect on nerve growth.
An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang.
When I was a kid I always had to mow the lawn, and not with those ones you ride like a toy.
/PRNewswire/ — Intelligent robotics brand MOWRATOR is targeting the North American market. MOWRATOR will launch the world’s first battery-powered all-in-one remote control robotic lawn mower, S1, globally in early 2024. MOWRATOR S1 debuted at the GIE Landscaping Equip Expo trade show in October 2023, followed by the Orlando Makers Faire in November 2023. MOWRATOR S1 received enthusiastic feedback from industry partners, landscaping professionals, and homeowners. Attendees were impressed by MOWRATOR S1’s all-metal frame with its 21 steel blade, autopilot L2 cruise control and U-turn, and one-button auto-dumping mechanism. Furthermore, MOWRATOR S1 also developed more modules to meet autumn leaf vacuum and other yard care needs, unique from the market’s standard remote control lawn mower.
Artificial intelligence could help speedily summarize research. But it comes with risks.
For most animals, ageing is a one-way journey. In a recent PNAS publication, researchers Joan Soto-Angel and Pawel Burkhardt discovered that a species of comb jelly can reverse its life cycle, returning from adulthood to a larval stage.
Embracing the paradigm shift of agentic AI could lead to massive advancements in healthcare as we know it.
A recent study links satellite and brain imaging data to identify how environmental factors can impact mental health, cognition and brain development in young people.
The research, published in the journal Nature Mental Health, is part of a collaboration involving a team of university researchers from around the world led by experts in the tri-institutional Center for Translational Research in Neuroimaging and Data Science (TReNDS Center) based at Georgia State University and New Light Technologies.
The study, titled “Urban-Satellite Estimates in the ABCD Study: Linking Neuroimaging and Mental Health to Satellite Imagery Measurements of Macro Environmental Factors,” represents an advance in understanding how specific environmental conditions may impact the brains of young people.
