🧠 Scientists find Autism traits come from Neanderthal DNA.

A new study just discovered that Neanderthal DNA is more common in autistic individuals, hinting at ancient roots of neurodiverse traits.

Traits linked to autism spectrum disorder today appear have deep evolutionary roots, according to new research connecting them to Neanderthal DNA.

After modern humans interbred with Neanderthals around 50,000 years ago, they inherited genetic variants that still influence people of Eurasian descent today.

Researchers from Clemson and Loyola Universities found that some of these inherited Neanderthal gene variants are more common in autistic individuals, particularly those affecting visual processing and brain regions involved in social behavior.

While the study doesn't claim that Neanderthal DNA directly causes autism, it adds to growing evidence that autism-related traits may reflect ancient human adaptations. Skills like intense focus, heightened perception, or precision thinking—often seen in autistic individuals—might once have offered survival advantages, such as tool-making or tracking patterns in the environment. These findings open a new window into the evolutionary origins of neurodiversity and challenge us to see autism not just as a modern diagnosis, but also as part of the broader human story.

Драги студенти,
Повелете 13 совети како да бидете добри студенти и да извлечете максимум од студиите:
1. Направете план – користете календар или апликација за да го распоредите времето за учење, предавања, вежби и одмор.
2. Поставете приоритети – секогаш прво решавајте ги најтешките или најитните задачи.
3. Не оставајте за утре – избегнувајте одлагање, учете редовно, не само пред испит.
4. Активно учење – правете белешки, прашувајте, дискутирајте со колеги.
5. Поделете го материјалот – учете во помали делови наместо да учите сè одеднаш.
6. Користете различни техники – мапи на умот, флеш-картички, сумирање, групно учење.
7. Добар сон – најмалку 7-8 часа за да имаете концентрација.
8. Физичка активност – спорт, прошетки или вежби за намалување на стрес.
9. Здрава исхрана – избегнувајте премногу кофеин и брза храна; овошјето, зеленчукот и водата се задолжителни.
10. Редовно присуствувајте – на предавања, вежби и семинари.
11. Поставувајте прашања – не се плашете да барате појаснување од професорите.
12. Чувајте го академскиот интегритет – избегнувајте препишување и плагијат.
13. Бидете љубопитни – истражувајте надвор од зададениот материјал.

📸 She took one of the most important photos in human history, and she was nearly erased from the story.

The image that revealed DNA's double helix was captured by Rosalind Franklin, whose critical work was shared without her consent.

Here's her story.

Rosalind Franklin’s “Photo 51” stands as one of the most important scientific images of the 20th century — a stunning X-ray diffraction image that revealed the helical structure of DNA. Taken in 1952 in the basement of the MRC Biophysics Unit at King’s College London, the photograph was captured by Franklin and her PhD student Raymond Gosling.

The clarity of the X-shaped pattern made it unmistakable: DNA was a double helix.

This revelation, shared James Watson and Francis Crick without Franklin’s knowledge by her colleague Maurice Wilkins, became the turning point for Watson and Crick, whose model of DNA would soon be published and credited as a breakthrough in molecular biology.

Watson described his first glimpse of it in The Double Helix: “The instant I saw the picture my mouth fell open and my heart began to race.” The implication is that Franklin did not appreciate the meaning of the image herself. And so, history gave the accolades to others.

Franklin was a brilliant X-ray crystallographer, she was also a woman in a male-dominated field, often marginalized and left out of key discussions. Despite contributing essential data that confirmed the double helix structure, Franklin’s role was underrecognized during her lifetime.

While Watson, Crick, and Wilkins went on to share the 1962 Nobel Prize, Franklin had already died of cancer at 37 and was never eligible for the honor. Still, it wasn't until decades later that the scientific community began to acknowledge that *she* was the one who captured the image of the structure of DNA, and so found its shape.

In the end, her meticulous work and scientific rigor laid the groundwork for one of biology’s most iconic discoveries.

The human brain, a marvel of biological engineering, operates at an astonishingly low power consumption of about 12 watts, roughly equivalent to a dim light bulb.

This efficiency stems from its highly optimized neural architecture, developed over millions of years of evolution.

Neurons in the brain communicate via electrochemical signals, leveraging ion channels and synaptic connections to process information.

This process is inherently analog, allowing the brain to perform complex tasks like pattern recognition, decision-making, and creativity with minimal energy.

The brain’s efficiency is further enhanced by its ability to operate in a low-power, parallel-processing mode, where billions of neurons work simultaneously without centralized control.

In contrast, current AI systems, such as large-scale neural networks, often require massive computational resources, consuming up to 2.7 billion watts in large data centers.

This inefficiency arises from the digital nature of AI, which relies on silicon-based processors and vast arrays of GPUs or TPUs.

These systems perform billions of matrix operations, requiring significant electrical power for computation, cooling, and data transfer.

Unlike the brain’s analog efficiency, AI’s digital computations are inherently power-hungry, especially for tasks like training large language models or processing real-time data.

The disparity—millions of times more energy for AI to achieve comparable cognitive tasks—highlights the brain’s evolutionary advantage.

However, AI’s energy demands are being addressed through innovations like neuromorphic computing, which mimics the brain’s structure, and more efficient algorithms.

While AI offers scalability and precision, closing the energy efficiency gap remains a critical challenge for future advancements, potentially revolutionizing technology’s sustainability.

Scientists just destroyed 99% of cancer cells using a near-infrared light.

No drugs, no scalpels.

In a groundbreaking advance, scientists have developed a technique that destroys 99% of cancer cells in lab tests using vibrating molecules activated by near-infrared light.

These molecules, known as aminocyanines, have long been used as dyes for cancer imaging, but researchers discovered they can also act as “molecular jackhammers” when stimulated to vibrate in unison.

This motion ruptures cancer cell membranes with extraordinary precision and speed—over a million times faster than previous molecular machines like Feringa-type motors. The method’s use of near-infrared light also allows deeper pe*******on into body tissues, potentially eliminating the need for invasive surgery.

Developed by scientists from Rice University and other Texas institutions, this approach showed impressive results in both lab-grown cancer cells and live mice with melanoma tumors, half of which became cancer-free.

The technique exploits a phenomenon called plasmons—vibrations of electrons within the molecule—which drive mechanical movement that breaks apart the cell membrane.

Because the process relies on physical force rather than chemical interaction, it may sidestep common drug resistance mechanisms in cancer treatment. While still in early stages, researchers believe this could represent a powerful new direction for cancer therapies.
