Can exercise affect the progression of Alzheimer’s disease?

Posted by in categories: biotech/medical, health, neuroscience

(NewsNation) — Studies have shown that Alzheimer’s may become the defining disease of the baby boomer generation.

According to The Alzheimer’s Association, the number of people age 65 and over living with Alzheimer’s now is nearly 7 million. That number is expected to rise to over 13 million by 2050.

Physician and best-selling author Dr. Ian Smith says it’s not known exactly what causes Alzheimer’s.

Fine Tuned Universe: the critics strike back

Posted by in categories: cosmology, mathematics, quantum physics

At the end of of 2022, we released a film offering a reply to the fine tuning argument for God from leading physicists and philosophers of physics. This included both those that doubt there is any fine tuning and those that think there is but it can be solved by naturalistic means.
Subsequently astrophysicist Luke Barnes and philosopher Philip Goff offered their criticism of our criticism. Here we have assembled some of our original talking heads to review their criticism and offer a reply, defending the original position that fine tuning argument for God does not work.
Our original film can be found here:

Luke Barnes and Philip Goff’s reply is here: and we also recommend this video on Bayes theorem on the Majesty of Reason Channel:

Tomorrow Biostasis: The Berlin Startup That Wants to Bring You Back from the Dead

Posted by in categories: biotech/medical, cryonics, life extension, neuroscience

What if death was not the end? What if, instead of saying our final goodbyes to loved ones, we could freeze their bodies and bring them back to life once medical technology has advanced enough to cure their fatal illnesses? This is the mission of Tomorrow Biostasis, a Berlin-based startup that specializes in cryopreservation.

Cryopreservation, also known as biostasis or cryonics, is the process of preserving a human body (or brain) in a state of suspended animation, with the hope that it can be revived in the future when medical technology has advanced enough to treat the original cause of death. This may seem like science fiction, but it is a legitimate scientific procedure, and Tomorrow Biostasis is one of the few companies in the world that offers this service.

Dr Emil Kendziorra, co-founder and CEO of Tomorrow Biostasis explained that the goal of cryopreservation is to extend life by preserving the body until a cure can be found for the original illness. He emphasized that cryopreservation is not a form of immortality, but rather a way to give people a second chance at life.

How tumors transform blood vessels

Posted by in category: biotech/medical

Increasingly dense cell clusters in growing tumors convert blood vessels into fiber-filled channels. This makes immune cells less effective, as findings by researchers from ETH Zurich and the University of Strasbourg suggest. Their research is published in Matrix Biology.

It was almost ten years ago that researchers first observed that tumors occurring in different cancers—including , breast cancer and melanoma—exhibit channels leading from the surface to the inside of the cell cluster. But how these channels form, and what functions they perform, long remained a mystery.

Through a series of elaborate and detailed experiments, the research groups led by Viola Vogel, Professor of Applied Mechanobiology at ETH Zurich, and Gertraud Orend from the University of Strasbourg have found possible answers to these questions. There is a great deal of evidence to suggest that these channels, which the researchers have dubbed tumor tracks, were once .

New ocean in making? Africa slowly splitting into two, scientists predict nature’s rarest move

Posted by in category: futurism

As Africa splits into two pieces, scientists predict the beginning of the rarest natural phenomena. Researchers believe that in the distant future, the creation of a new ocean may result in the division of Africa into two pieces. The separation of two significant portions of the continent may eventually lead to the formation of a new body of water. In millions of years, landlocked nations like Zambia and Uganda might have their own coasts.

The splitting of an one tectonic plate into two or more tectonic plates divided by divergent plate borders is known as rifting, according to Science Direct. Where the Earth’s tectonic plates separate, a lowland area known as the rift valley arises, according to National Geographic.

These rift valleys can be found both on land and on the ocean’s floor. According to IFLScience research, this event dates back at least 138 million years to the time when South America and Africa became separated into separate continents. According to NBC News, the Red Sea and the Gulf of Aden were formed as a result of the Arabian plate moving away from Africa for the past 30 million years.

Mirror-imaging in molecules can modify neuron signaling

Posted by in categories: neuroscience, particle physics

With the aid of some sea slugs, University of Nebraska–Lincoln chemists have discovered that one of the smallest conceivable tweaks to a biomolecule can elicit one of the grandest conceivable consequences: directing the activation of neurons.

Their discovery came from investigating peptides, the short chains of amino acids that can transmit signals among cells, including neurons, while populating the central nervous systems and bloodstreams of most animals. Like many other molecules, an amino acid in a peptide can adopt one of two forms that feature the same atoms, with the same connectivity, but in mirror-image orientations: L and D.

Chemists often think of those two orientations as the left and right hands of a molecule. The L orientation is by far the more common in peptides, to the point of being considered the default. But when enzymes do flip an L to a D, the seemingly minor about-face can turn, say, a potentially therapeutic molecule into a toxic one, or vice versa.
