Nov. 6, 2024 By scanning the brains of people while they watched movie clips, neuroscientists have created the most detailed functional map of the brain to date. The fMRI analysis shows how different brain networks light up when participants viewed short clips from a range of independent and Hollywood films including Inception, The Social Network, and Home Alone. The team identified different brain networks ...

Nov. 6, 2024 Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, reports a research team. This type of reaction probably plays an important role in the formation of complex organic molecules in the universe -- and possibly in the origin of life. They also open up new strategies for the industrial ...

Nov. 6, 2024 Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system harbored a weak magnetic field, which could have played a role in forming the giant planets and other ...

Nov. 6, 2024 Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals. A team has observed that this species forms multicellular structures that bear striking similarities to animal embryos. These observations suggest that the genetic ...

Nov. 5, 2024 At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results provide the first direct geochemical evidence of the slushy planet -- otherwise known as the 'plume-world ocean' era -- when sky-high carbon dioxide levels forced the frozen Earth into a massive, rapid melting ...

Nov. 5, 2024 New research has shown that bio-based fibers caused higher mortality, and reduced growth and reproductivity, among earthworms -- a species critical to the health of soils globally -- than conventional plastics. It has led scientists to suggest that materials being advocated as alternatives to plastic should be tested thoroughly before they are ...

Nov. 5, 2024 Hydrogen, a promising fuel, has extensive applications in many sectors. However, its safe and widespread use necessitates reliable sensing methods. While tunable diode laser absorption spectroscopy (TDLAS) has proved to be an effective gas sensing method, detecting hydrogen using TDLAS is difficult due to its weak light absorption property in the ...
