When discussing motors, most people think of those in vehicles or machines. However, biological motors have existed for millions of years in microorganisms. Many bacteria use tail-like structures called flagella, which rotate to propel them through fluids. This movement is driven by a protein complex known as the flagellar motor.

The flagellar motor has two key components: the rotor and the stators. The rotor, a large rotating structure anchored to the cell membrane, drives flagellum movement. The stators, smaller structures surrounding the rotor, contain ion pathways that transport protons or sodium ions, depending on the bacterial species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

In today’s AI news, Backed by $200 million in funding, Scott Wu and his team at Cognition are building an AI tool that could potentially disintegrate the whole industry, at a $2 Billion valuation. Devin is an autonomous AI agent that, in theory, writes the code itself—no people involved—and can complete entire projects typically assigned to developers.

In other advancements, OpenAI is changing how it trains AI models to explicitly embrace “intellectual freedom … no matter how challenging or controversial a topic may be,” the company says in a new policy. OpenAI is releasing a significantly expanded version of its Model Spec, a document that defines how its AI models should behave — and is making it free for anyone to use or modify.

Then, xAI, the artificial intelligence company founded by Elon Musk, is set to launch Grok 3 on Monday, Feb. 17. According to xAI, this latest version of its chatbot, which Musk describes as “scary smart,” represents a major step forward, improving reasoning, computational power and adaptability. Grok 3’s development was accelerated by its Colossus supercomputer, which was built in just eight months, powered by 100,000 Nvidia H100 GPUs.

And, large language models can learn complex reasoning tasks without relying on large datasets, according to a new study by researchers at Shanghai Jiao Tong University. Their findings show that with just a small batch of well-curated examples, you can train an LLM for tasks that were thought to require tens of thousands of training instances.

A team of researchers has unveiled an innovative additive that significantly enhances the lifespan and efficiency of lithium-air batteries. This advancement, announced on Feb. 10, potentially more than doubles the driving range of vehicles compared to those using traditional lithium-ion batteries. The research was spearheaded by Prof. Kwak Won-jin from the Ulsan National Institute of Science and Technology (UNIST), in collaboration with Prof. Seo Seong-eun from Ajou University and Prof. Chen Shuming from Oberlin College in the United States.

Lithium-air batteries, known for their high energy density, use lithium as the anode and oxygen from the air as the cathode, offering up to five times the capacity of conventional lithium-ion batteries. However, these batteries face challenges due to the formation of reactive oxygen species (ROS) during operation, which can degrade battery components and reduce efficiency. The newly developed additive, a ‘redox mediator’ named BAC, addresses these challenges by maintaining a consistent charging voltage level of 3.5V, even after exposure to singlet oxygen, a particularly reactive form of oxygen.

The redox mediator, although comprising only 5% of the battery electrolyte’s weight, plays a crucial role in determining the energy efficiency and lifespan of lithium-air batteries. By reducing the voltage required for charging, the BAC mediator enhances energy efficiency and minimizes battery overload, thereby extending its lifespan. Researcher Lee Hyun-wook, the first author of the study, explained, “We were able to develop such a redox mediator through a design method that analyzes the molecular stereostructure.”

A recent study published in Science investigates the underlying mechanisms of endothelial insulin resistance involved in obesity-associated diabetes.

What causes insulin resistance?

Diabetes is a chronic disease that occurs when the body cannot adequately produce or use insulin, a hormone that facilitates the transportation of glucose from the blood into cells for energy. The activation of insulin receptors, which are highly expressed on the luminal side of endothelial cells, induces endothelial nitric oxide (NO)-synthase (eNOS) activity. Subsequently, NO-mediated vasodilation allows insulin to reach metabolic target cells including adipocytes, skeletal muscle cells, and hepatocytes.

Chinese artificial intelligence startup DeepSeek’s latest AI model sparked a $1 trillion rout in US and European technology stocks, as investors questioned bloated valuations for some of America’s biggest companies.
DeepSeek’s latest AI model rose to the top of the Apple’s appstore charts over the weekend, presenting a visible challenge to costlier models like OpenAI and raising questions over the hundreds of billions in planned spending on the technology by the likes of Microsoft Corp., Meta Technologies Inc. and Alphabet Inc.
It also put a spotlight AI chip producer Nvidia Corp., whose shares soared ninefold in the past two years, making it the highest-valued company in the world. The Santa Clara, California-based firm slid more 10% in premarket trading Monday — a drop that would zap about $340 billion in market value if it were to hold in the cash session.
Nasdaq 100 futures tumbled as much as 5.2% in overnight trading before paring the loss to 3.9% as of 7:30 a.m. in New York. That marked the biggest intraday drop for the contracts since August. In Europe, tech stocks led market losses, with shares of chip equipment maker ASML Holding NV down as much as 12%. The Cboe Volatility Index, known as the VIX, surged to 21.5. The Nasdaq 100 and Europe’s Stoxx 600 technology sub-index were together set for a market capitalization wipeout of $1.2 trillion, if the losses hold.
