Scientists Discover Game-Changing Therapy to Combat High Cholesterol

Using human stem cells, they found compounds that lower cholesterol without relying on the usual pathways, providing a fresh approach to treating the condition.

A Hidden Clue in the Mona Lisa

Leonardo da Vinci’s Mona Lisa is one of the most famous paintings in the world. However, what many people don’t know is that it may also hold a clue to a medical condition called familial hypercholesterolemia (FH). Experts believe that the subtle fat deposits visible on her hands, known as xanthomas, could be early evidence of this genetic disorder.

Breakthrough: New Register Loaded with Thousands of Entangled Nuclei

In a monumental stride toward the realization of practical quantum computing and advanced quantum networks, researchers at the prestigious Cavendish Laboratory of the University of Cambridge have successfully crafted a fully operational quantum register utilizing the atomic properties within a semiconductor quantum dot. This innovative development could pave the way for pivotal advancements in quantum information technology, crucial for the anticipated future where quantum networking integrates into everyday digital communications.

This breakthrough is detailed in a publication in Nature Physics, where it reveals the introduction of an entirely new category of qubits that are optically interconnected. As the field of quantum networking progresses, the need for stable, scalable, and adaptable quantum nodes has become increasingly evident. The research team’s focus on quantum dots is particularly advantageous, as these nanoscale entities possess unique optical and electronic attributes intrinsic to quantum mechanical phenomena.

Quantum dots have demonstrated considerable potential in existing technologies, such as medical imaging and display screens, primarily due to their efficacy as bright single-photon sources. However, to create functional quantum networks, it is essential not only to emit single photons but also to establish reliable qubits that can effectively interact with these emitted photons. Moreover, these qubits must be capable of locally storing quantum information over extended periods. The researchers’ development enhances the inherent spins of the nuclear atoms within the quantum dots, optimizing them into a cohesive many-body quantum register.

Block Launches Open-Source AI Agent Goose As Jack Dorsey Praises DeepSeek’s Development Approach

In today’s AI news, Block announced the launch of Goose, an open-source AI agent that allows developers to customize the tool for different purposes and using different large language models. Block’s move comes just after the Chinese startup DeepSeek unveiled its R1 artificial intelligence model, a rival to leading U.S. AI providers.

Two huge, continental-sized islands discovered in Earth’s mantle

Scientists have discovered two enormous structures deep within Earth’s mantle. Research from Utrecht University reveals these regions are hotter and older than the surrounding sunken tectonic plates—at least half a billion years old, possibly older.

This finding challenges the idea that Earth’s mantle is well-mixed and fast-flowing, suggesting less movement in the mantle than previously thought.

Large earthquakes make the Earth vibrate like a bell with different tones. Seismologists study these tones to understand Earth’s interior. If the tones are “out of tune” or quieter, it indicates anomalies, helping to create images of Earth’s interior, similar to X-rays for doctors.

We Might Finally Know How The Brain Refreshes Itself at Night

As you lay your head down to sleep tonight and dream all things weird and wonderful, scientists think your brain is going through a gentle rinse cycle, washing away a day’s worth of toxic by-products in preparation for a new day of thinking ahead.

But the mechanisms behind this neurological cleansing system have yet to be described in detail.

Now researchers from the University of Copenhagen have applied a suite of technologies to map the subtle rise and fall of neurotransmitters, blood volume, and spinal fluid in mice as they go about their day.

Oral Microbiome May Influence Cognitive Decline and Brain Health

The microbial ecosystems within our mouths may affect our cognitive function as we age, according to a study. Interventions such as prebiotics, including dietary nitrate, have potential for delaying cognitive decline.

About 15% of older adults have mild cognitive impairment, which is the largest risk factor for the development of dementia or Alzheimer’s disease. There is a known association between periodontitis—gum disease—and worsened cognitive function.

Maintaining Telomeres Extends Lifespan in Mice

A recent study has found that the overexpression of telomerase reverse transcriptase (TERT), which is a subunit of telomerase, an enzyme essential for telomere maintenance, leads to lifespan extension in mice without significant side effects [1].

Protecting DNA

Telomere shortening is a well-known hallmark of aging. Telomeres are protective DNA sequences at the ends of the chromosomes. In most human cells, they become shorter with each division.
