Stresses and hydrodynamics: Scientists uncover new organizing principles of the genome

Posted by in categories: bioengineering, biotech/medical

A team of scientists has uncovered the physical principles—a series of forces and hydrodynamic flows—that help ensure the proper functioning of life’s blueprint. Its discovery provides new insights into the genome while potentially offering a new means to spot genomic aberrations linked to developmental disorders and human diseases.

“The way in which the is organized and packed inside the nucleus directly affects its biological function, yet the physical principles behind this organization are far from understood,” explains Alexandra Zidovska, an associate professor in New York University’s Department of Physics and an author of the paper, which appears in the journal Physical Review X (PRX). “Our results provide fundamental insights into the biophysical origins of the organization of the genome inside the .”

Possible Location of the Universe Inside A Fourth-Dimensional Black Hole

Posted by in categories: cosmology, singularity

Our universe is so vast that it appears impossible for anything else to exist. Experts are beginning to suspect that our universe might exist inside a fourth-dimensional black hole.

Our cosmos began as a singularity, a point in space that was endlessly hot and dense. According to researchers at CERN such as James Beecham, black holes in our universe may have the same characteristics as those described by the scientific community.

Astronomers discover irregularities in the cores of red giants

Posted by in category: cosmology

Red giants are dying stars, in advanced stages of stellar evolution, which have depleted the hydrogen in their cores. In a study published today in Nature Communications, a team of astronomers mainly from Instituto de Astrofísica e Ciências do Espaço (IA), have found new evidence that red giant stars experience “glitches”—sharp structural variations—in their inner core.

Unfortunately, it is impossible to look directly inside a star. However, a technique dubbed asteroseismology, which measures oscillations similar to “earthquakes” in stars, can provide indirect glimpses of stellar interiors. The “glitches” can affect these oscillations, or the frequencies and paths of gravity and traveling through the stellar interior.

Quantum Experiment Breaks Reality

Posted by in category: quantum physics

We are aware of how skewed our perception of reality is. How we see the world is shaped by our senses, our societies, and our knowledge.

And you may want to rethink your belief that science will always provide you with an objective reality.

Science Confirms Our Life Really Does Flash Before Your Eyes Before Death

Posted by in categories: biotech/medical, science

Death is perhaps one of the most universally discussed topics across the board, and at least once in our lives, the vast majority of us wonder what happens during our final moments. For a long time, we haven’t had many answers, well, that is until now.

One of the most common ‘rumors’ about death is that right before our final moment, our life flashes before our eyes. And recent research may offer some interesting answers that indicate this theory isn’t far from the truth.

The research was carried out by accident, as they had intended to study the brainwaves of an 87-year-old patient with epilepsy. However, during their research, the patient ended up suffering from a fatal heart attack. During the death of the patient, their brainwaves were recorded up until the moment of death.

Scientists discover what was on the menu of the first dinosaurs

Posted by in categories: computing, existential risks, food

The earliest dinosaurs included carnivorous, omnivorous and herbivorous species, according to a team of University of Bristol paleobiologists.

By looking at the tooth shapes of the earliest dinosaurs and simulating their tooth function with computational modeling, experts were able to compare them to living reptiles and their diets. Their findings, published December 16 in Science Advances, show that many groups of plant-eating dinosaurs were ancestrally omnivorous and that the ancestors of our famous long-necked herbivores, such as Diplodocus, ate meat. This ability to diversify their diets early in their evolution likely explains their evolutionary and ecological success.

The earliest dinosaurs are enigmatic: they were much smaller than their later relatives and for most of the Triassic they were in the shadow of the crocodile-like reptiles. It is unknown how diverse they were in terms of diets and ecology, but scientists know something must have happened in the Triassic that allowed dinosaurs to endure the Triassic–Jurassic mass extinction and adapt in its aftermath, becoming the for the rest of the Mesozoic.
