Physicists propose new way to search for dark matter: Small-scale solution could be key to solving large-scale mystery

Posted by in categories: cosmology, particle physics, quantum physics

Ever since its discovery, dark matter has remained invisible to scientists despite the launch of multiple ultra-sensitive particle detector experiments around the world over several decades.

Now, physicists at the Department of Energy’s (DOE) SLAC National Accelerator Laboratory are proposing a new way to look for using quantum devices, which might be naturally tuned to detect what researchers call thermalized dark matter.

Most dark matter experiments hunt for galactic dark matter, which rockets into Earth directly from space, but another kind might have been hanging around Earth for years, said SLAC physicist Rebecca Leane, who was an author of the new study.

A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations

Posted by in categories: particle physics, quantum physics

Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying systems comprised of several strongly interacting particles (i.e., many body systems) in two or more dimensions, numerically predicting the amount of information shared between these particles, a measure known as entanglement entropy (EE), becomes highly challenging.

Memories of mitosis: Molecular mechanism that detects defects during cell division could aid cancer treatment

Posted by in categories: biotech/medical, genetics

Every day, our cells are hard at work multiplying. Cell division is a precise process, but sometimes this process is impaired and diseases like cancer occur. Mitosis is one of the most important phases in the cell cycle. During this phase, a cell’s DNA is split into two equal sets of chromosomes and it divides into two genetically identical daughter cells.

Model suggests how ancient RNA may have gained self-cutting ability essential for life

Posted by in categories: biotech/medical, chemistry, genetics

Scientists have long pondered the beginnings of life on Earth. One theory is that RNA, which is ubiquitous across all domains of life, played a central role in early life. Similar to DNA, RNA possesses the ability to store genetic information. However, to initiate life’s processes, early RNA must have also possessed the capability to self-replicate and catalyze biochemical reactions independently, without the assistance of specialized enzymes.

Constructing ‘on-gel’ alveolar organoids as a new screening platform

Posted by in categories: biotech/medical, chemistry

A study led by Professor Shimpei Gotoh (Department of Clinical Application), introduces a new culturing method to generate alveolar organoids suitable for medium-and high-throughput screening and identified several chemicals with synergistic effects on AT1 cell differentiation. The work is published in the journal Stem Cell Reports.

Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips

Posted by in categories: chemistry, computing

Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however, scientists from the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) have developed a molecule that takes the possibilities of photoswitches a step further.

How did nervous systems, with their incredible complexity, evolve across different species?

Posted by in category: neuroscience

New research supported by the Wu Tsai Neurosciences Institute’s Interdisciplinary Postdoctoral Scholars program zeroes in on the surprising observation that many genes found in brain cells and synapses—the points of communication between neurons—are among the largest in the animal kingdom.

Microsoft and OpenAI reportedly plan to build a $100 billion AI supercomputer called “Stargate”

Posted by in categories: robotics/AI, supercomputing

According to insiders, Microsoft and OpenAI are planning to build a $100 billion supercomputer called “Stargate” to massively accelerate the development of OpenAI’s AI models, The Information reports.

Microsoft and OpenAI executives are forging plans for a data center with a supercomputer made up of millions of specialized server processors to accelerate OpenAI’s AI development, according to three people who took part in confidential talks.

The project, code-named “Stargate,” could cost as much as $100 billion, according to one person who has spoken with OpenAI CEO Sam Altman about it and another who has seen some of Microsoft’s initial cost estimates.
