Combining polarized light methods reveals hidden molecular orientations with precision

Image quality often makes the difference between an amazing multimedia experience, like feeling immersed in a high-definition movie, and a visual letdown. When it comes to biomolecular imaging, the details matter even more. When scientists increase resolution in quantitative imaging, they improve accuracy and confidence in results, ultimately facilitating discoveries in studies of proteins, cells and other biomedical applications.

Scientists have long been able to look at to study their nanoscale structures and dynamics in . However, distinguishing between two closely spaced dipole emitters, which are that can emit light in specific directions and intensities, has remained a major challenge, especially when such molecules emit light at the same time and are spatially coincident, or located at nearly the same point in space.

This limitation has hindered researchers’ ability to measure the orientation and angular separation of dipoles accurately, which is vital to understanding their rotational dynamics in crowded cellular environments.

Scientists Just Merged Human Brain Cells With AI – Here’s What Happened!
What happens when human brain cells merge with artificial intelligence? Scientists have just achieved something straight out of science fiction—combining living neurons with AI to create a hybrid intelligence system. The results are mind-blowing, and they could redefine the future of computing. But how does it work, and what does this mean for humanity?

In a groundbreaking experiment, researchers successfully integrated human brain cells with AI, creating a system that learns faster and more efficiently than traditional silicon-based computers. These “biocomputers” use lab-grown brain organoids to process information, mimicking human thought patterns while leveraging AI’s speed and scalability. The implications? Smarter, more adaptive machines that think like us.

Why is this such a big deal? Unlike conventional AI, which relies on brute-force data crunching, this hybrid system operates more like a biological brain—learning with less energy, recognizing patterns intuitively, and even showing early signs of creativity. Potential applications include ultra-fast medical diagnostics, self-improving robots, and brain-controlled prosthetics that feel truly natural.

But with great power comes big questions. Could this lead to conscious machines? Will AI eventually surpass human intelligence? And what are the ethical risks of blending biology with technology? This video breaks down the science, the possibilities, and the controversies—watch to the end for the full story.

How did scientists merge brain cells with AI? What are biocomputers? Can AI become human-like? What is hybrid intelligence? Will AI replace human brains?This video will answer all these question. Make sure you watch all the way though to not miss anything.

Planarian worms can regenerate into a more youthful version of themselves

As you age you naturally lose neurons and muscle mass and experience a decline in fertility and wound healing ability. Previous research in animals has offered several potential techniques for turning back the biological clock in specific tissues, including exercise and calorie restriction. However, age reversal of blood cells or at whole organism level has so far been elusive.

Breakthroughs in Stopping Aging

Japanese researchers are making groundbreaking discoveries on the mechanisms of aging and working to apply them. As we age, senescent cells, or aged cells that have stopped dividing, accumulate, causing inflammation that can damage blood vessels and organs. Animal experiments have shown that removing these cells improves kidney function and reduces arteriosclerosis. They have led to the identification of a drug and development of a vaccine to eliminate the cells.

NAD+ Controls Circadian Reprogramming through PER2 Nuclear Translocation to Counter Aging

Disrupted sleep-wake and molecular circadian rhythms are a feature of aging associated with metabolic disease and reduced levels of NAD+, yet whether changes in nucleotide metabolism control circadian behavioral and genomic rhythms remains unknown. Here, we reveal that supplementation with the NAD + precursor nicotinamide riboside (NR) markedly reprograms metabolic and stress-response pathways that decline with aging through inhibition of the clock repressor PER2. NR enhances BMAL1 chromatin binding genome-wide through PER2 K680 deacetylation, which in turn primes PER2 phosphorylation within a domain that controls nuclear transport and stability and that is mutated in human advanced sleep phase syndrome.

Sound therapy effectively reduces motion sickness by stimulating inner ear

A research group led by Takumi Kagawa and Masashi Kato at Nagoya University Graduate School of Medicine has discovered that using “a unique sound stimulation technology”—a device that stimulates the inner ear with a specific wavelength of sound—reduces motion sickness. Even a single minute of stimulation reduced the staggering and discomfort felt by people that read in a moving vehicle.

The results, published in Environmental Health and Preventive Medicine, suggest a simple and effective way to treat this common disorder.

“Our study demonstrated that short-term using a unique sound called ‘sound spice’ alleviates symptoms of motion sickness, such as nausea and dizziness,” Kagawa said. “The effective sound level falls within the range of everyday environmental noise exposure, suggesting that the sound technology is both effective and safe.”

How to prevent chronic inflammation from zombie-like cells that accumulate with age

In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way.

Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as senescence where they persist but no longer divide to make new cells. Our bodies can remove these senescent cells that tend to pile up as we age. The older we get, however, the less efficient our immune systems become at doing so.

“In addition to no longer growing and proliferating, the other hallmark of senescent cells is that they have this inflammatory program causing them to secrete inflammatory molecules,” said Peter Adams, Ph.D., director and professor of the Cancer Genome and Epigenetics Program at Sanford Burnham Prebys and senior and co-corresponding author of the study.
