Can Cells Think? The Magic of Developmental Biology

Posted by in categories: biological, cosmology, evolution, neuroscience

The John Templeton Foundation recently invited biologist Michael Levin to speak to a small group about the presence of agency and cognition in the most fundamental forms of life, even at the levels of cells and tissues. In the recorded video, Dr. Levin, who directs a developmental biology lab at Tufts University, discusses with Philip Ball, a science writer and author of the newly published Book of Minds: How to Understand Ourselves and Other Beings.

Founded in 1987, the John Templeton Foundation supports research and dialogue on the deepest and most perplexing questions facing humankind. The Foundation funds work on subjects ranging from black holes and evolution to creativity, forgiveness, and free will. It also encourages civil, informed dialogue among scientists, philosophers, theologians, and the public at large.

New study challenges Einstein and Newton’s theories of gravity

Posted by in categories: cosmology, physics

No, it’s not dark matter.

Gravity is the force that attracts objects toward the Earth and maintains the orbital motion of planets around the Sun. Our scientific understanding of gravity was established by Isaac Newton.

Math Proof Draws New Boundaries Around Black Hole Formation

Posted by in categories: cosmology, mathematics

For a half century, mathematicians have tried to define the exact circumstances under which a black hole is destined to exist. A new proof shows how a cube can help answer the question.

Could white holes actually exist?

Posted by in categories: cosmology, singularity

Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they?

To understand the nature of white holes, first we have to examine the much more familiar black holes. Black holes are regions of complete gravitational collapse, where gravity has overwhelmed all other forces in the universe and compressed a clump of material all the way down to an infinitely tiny point known as a singularity. Surrounding that singularity is an event horizon, which is not a physical, solid boundary, but simply the border around a singularity where the gravity is so strong that nothing, not even light, can escape.

Gravitational waves show black holes prefer certain masses before they collide

Posted by in categories: cosmology, physics

A preference for “universal masses” 9 and 16 times the mass of our Sun have been identified in the gravitational-wave events detected so far.

A quantum leap in mechanical oscillator technology

Posted by in categories: computing, cosmology, quantum physics

Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create quantum states in macroscopic mechanical objects.

By coupling these mechanical oscillators to light photons—known as “optomechanical systems”—scientists have been able to cool them down to their lowest energy level close to the , “squeeze them” to reduce their vibrations even further, and entangle them with each other. These advancements have opened up new opportunities in , compact storage in quantum computing, fundamental tests of quantum gravity, and even in the search for dark matter.

In order to efficiently operate optomechanical systems in the quantum regime, scientists face a dilemma. On one hand, the mechanical oscillators must be properly isolated from their environment to minimize ; on the other hand, they must be well-coupled to other such as electromagnetic resonators to control them.

New Theory Suggests Quantum Entanglement And Wormholes Are Linked Together

Posted by in categories: computing, cosmology, particle physics, quantum physics

Practical applications for quantum entanglement have already been proposed, as entangled particles have been suggest for use in powerful quantum computers and “impossible” to crack networks. Now, it seems quantum entanglement may be linked to wormholes.

Entangled wormholes.

Webb reveals colors, features of most distant star ever detected

Posted by in category: cosmology

Webb’s NIRCam (Near-Infrared Camera) instrument reveals the star, nicknamed Earendel, to be a massive B-type star more than twice as hot as our sun, and about a million times more luminous. (Image: NASA, ESA, CSA, D. Coe (STScI/AURA for ESA; Johns Hopkins University), B. Welch (NASA’s Goddard Space Flight Center; University of Maryland, College Park). Image processing: Z. Levay.)

The star in the very distant universe, and a billion years after the big bang, was captured by the observatory’s Near-InfraRed Camera instrument.
