Unlocking the Secrets of Consciousness: New Brain Imaging Study Illuminates Critical Connections

Posted by in categories: biotech/medical, neuroscience

Researchers identified a subcortical brain network that is thought to combine arousal and awareness, playing a key role in human consciousness.

A study recently published in Science Translational Medicine by researchers from Massachusetts General Hospital and Boston Children’s Hospital, both part of the Mass General Brigham healthcare system, introduces a connectivity map of a brain network. This map, the researchers suggest, is essential for maintaining human consciousness.

The study involved high-resolution scans that enabled the researchers to visualize brain connections at submillimeter spatial resolution. This technical advance allowed them to identify previously unseen pathways connecting the brainstem, thalamus, hypothalamus, basal forebrain, and cerebral cortex.

Unlocking High Energy: New Aqueous Batteries Surpass Traditional Limits

Posted by in categories: chemistry, energy, physics

Traditional lithium-ion batteries, while offering high energy density, have compromised safety because they use flammable organic electrolytes.

Aqueous batteries use water as the solvent for electrolytes, significantly enhancing the safety of the batteries. However, due to the limited solubility of the electrolyte and low battery voltage, aqueous batteries typically have a lower energy density. This means that the amount of electricity stored per unit volume of aqueous battery is relatively low.

In a new study published in Nature Energy, a research group led by Prof. Li Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Fu Qiang’s group also from DICP, developed a multi-electron transfer cathode based on bromine and iodine, realizing a specific capacity of more than 840 Ah/L, and achieving an energy density of up to 1,200 Wh/L based on catholyte in full battery testing.

Cosmic Revelation: MIT Uncovers a New Space Molecule

Posted by in category: space travel

MIT ’s discovery of 2-methoxyethanol in space reveals new insights into the development of molecular complexity in space during star formation.

New research from the group of MIT Professor Brett McGuire has revealed the presence of a previously unknown molecule in space. The team’s open-access paper, “Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observations of NGC 6334I,” was published in The Astrophysical Journal Letters.

Zachary T.P. Fried, a graduate student in the McGuire group and the lead author of the publication, worked to assemble a puzzle comprised of pieces collected from across the globe, extending beyond MIT to France, Florida, Virginia, and Copenhagen, to achieve this exciting discovery.

Physicists Discover “Topological Hall Effect” in Two-Dimensional Quantum Magnets

Posted by in category: quantum physics

Researchers from the High Magnetic Field Center of the Hefei Institutes of Physical Science of the Chinese Academy of Sciences and the University of Science and Technology of China recently introduced the concept of the “Topological Kerr Effect” (TKE). This new concept was developed using the low-temperature magnetic field microscopy system and magnetic force microscopy imaging system available at the steady-state high magnetic field experimental facility.

The findings, published in Nature Physics, hold significant promise for advancing our understanding of topological magnetic structures.

‘Cosmic glitch’ discovered in gravity’s behavior challenges Einstein’s general relativity theory

Posted by in categories: cosmology, physics

Researchers have stumbled upon a phenomenon that could rewrite our understanding of the universe’s gravitational forces. Known as the “cosmic glitch,” this discovery highlights anomalies in gravity’s behavior on an immense scale, challenging the established norms set by Albert Einstein’s theory of general relativity.

For over a century, general relativity has served as the backbone for our understanding of cosmic phenomena, ranging from the dynamics of the Big Bang to the intricacies of black holes. The theory posits that gravity influences not only the three spatial dimensions but also time itself.

Validated through numerous tests and observations, general relativity has been a robust model that physicists and astronomers worldwide rely on.

DARPA Selects Northrop Grumman, Umbra for Phase II of DRIFT Program

Posted by in categories: information science, military, satellites

Northrop Grumman and Umbra have been awarded small contracts by the Defense Advanced Research Projects Agency (DARPA) to continue to the second phase of a program designed to collect data from radar-equipped satellites flying in formation and develop innovative algorithms to process the data for military applications.

Umbra’s contract under the Distributed Radar Image Foundation Technology (DRIFT) program is for $6 million and will last for six months and Northrop Grumman’s is for $2 million and covers one year, a DARPA spokesperson said.
