Neuronal activity shapes the development of astrocytes, shows study

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

Researchers at Baylor College of Medicine have unraveled the processes that give astrocytes, the most abundant glial cell in the brain, their special bushy shape, which is fundamental for brain function. They report in the journal Nature that neuronal activity is necessary and sufficient for astrocytes to develop their complex shape, and interrupting this developmental process results in disrupted brain function.

“Astrocytes play diverse roles that are vital for proper ,” said first author Yi-Ting Cheng, a graduate student in Dr. Benjamin Deneen’s lab at Baylor. “For instance, they support the activity of other essential brain cells, neurons; participate in the formation and function of synapses, or neuron-to-neuron connections; release neurotransmitters, chemicals that mediate neuronal communication; and make the .”

In the adult brain, the bushy shape of is fundamentally linked to effective brain function. The ends of the branched-out astrocyte structure interact with neurons and regulate synaptic activity.

Today in the Moscone Center, San Francisco, at RSA Conference 2023 (RSAC), Google Cloud announced Google Cloud Security AI Workbench, a security platform powered by Sec-PaLM, a large language model (LLM) designed specifically for cybersecurity use cases.

Sec-PaLM modifies the organization’s existing PaLM model and processes Google’s proprietary threat intelligence data alongside Mandiant’s frontline intelligence to help identify and contain malicious activity, and coordinate response actions.

Vast Potential — Researchers Create a New Type of Laser

Posted by in categories: energy, materials

Researchers from EPFL and IBM have created a novel laser that could revolutionize optical ranging technology. This laser is constructed from lithium niobate, a material frequently utilized in optical modulators to regulate the frequency or intensity of light transmitted through a device.

Lithium niobate is highly valued for its ability to manage large amounts of optical power and its high “Pockels coefficient.” This allows the material to alter its optical properties when an electric field is applied to it.

The researchers achieved their breakthrough by combining lithium niobate with silicon nitride, which allowed them to produce a new type of hybrid integrated tunable laser. To do this, the team manufactured integrated circuits for light (“photonic integrated circuits”) based on silicon nitride at EPFL, and then bonded them with lithium niobate wafers at IBM.

Tesla receives massive fleet order from the UAE

Posted by in categories: space, sustainability

Tesla received a large order for Model 3s from an Emirati taxi company, Arabia Taxi Dubai, helping the company to cut its carbon footprint.

Tesla’s retail consumer pressure is undeniably large. Still, the automaker has also grown in popularity in the commercial space, especially from customers looking to cut operating costs while reducing their carbon footprints. Predominantly, these orders have been coming from ride-hailing companies and car rental services. Now, a Dubai-based taxi company is also looking to capitalize on the cut-cutting opportunity.

According to the announcement from Arabia Taxi Dubai, it will buy 269 Tesla Model 3s to become part of its taxi fleet in the United Arab Emirates. Currently, Arabia Taxi advertises itself as the largest taxi fleet in Dubai and one of the largest in the country. With this new purchase, it looks to double down on that lead.

Unraveling the Genetic Mechanisms Behind Long-Lasting Memories in the Brain

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

Summary: Researchers shed new light on the molecular and genetic basis of long-term memory formation in the brain. A new study reveals a single stimulation to the synapses of hippocampal neurons triggered numerous cycles where the memory-coding Arc gene produced mRNA molecules that were then translated into synapse-strengthening Arc proteins. From the findings, researchers determined a novel feedback loop that helps explain how short-lived mRNA and proteins create long-term memories in the brain.

Genetic Driver of Anxiety Discovered

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

Summary: An international team of scientists has identified a gene in the brain responsible for anxiety symptoms and found that modifying the gene can reduce anxiety levels, offering a novel drug target for anxiety disorders. The discovery highlights a new amygdala miR483-5p/Pgap2 pathway that regulates the brain’s response to stress and provides a potential therapeutic approach for anxiety disorders.

Scientists Use Electricity to Make Wounds Heal 3x Faster

Posted by in category: biotech/medical

Scientists have developed a specially engineered biochip that uses electricity to heal wounds up to three times faster than normal.

It’s well known that electric fields can guide the movements of skin cells, nudging them towards the site of an injury for instance. In fact, the human body generates an electric field that does this naturally. So researchers from the University of Freiburg in Germany set out to amplify the effect.

While it might not heal severe injuries with the speed of a Marvel superhero, it could radically reduce the time it takes for small tears and lacerations to recover.

Researchers Took The First Pics Of DEATH — It Is Actually PALE BLUE And Looks Nice

Posted by in categories: biological, existential risks

In today’s well-researched world, death is one of those unknown barriers. It was pursued by British scientists… The color of death is a faint blue.

British scientists got a firsthand look at what it’s like to die. They took a close look at the worm in the experiment. During this stage of passage, cells will perish. It starts a chain reaction that leads to the creature’s extinction and destroys cell connections.

AI-powered dance animator applies generative AI to choreography

Posted by in categories: media & arts, robotics/AI

Stanford University researchers have developed a generative AI model that can choreograph human dance animation to match any piece of music. It’s called Editable Dance GEneration (EDGE).

“EDGE shows that AI-enabled characters can bring a level of musicality and artistry to animation that was not possible before,” says Karen Liu, a professor of computer science who led a team that included two student collaborators, Jonathan Tseng and Rodrigo Castellon, in her lab.
