Does the enormous computing power of neurons mean consciousness can be explained within a purely neurobiological framework, or is there scope for quantum computation in the brain?
Researchers pin down the contentious notion that ideas from the strange world of quantum mechanics underpin plants’ skill at harvesting sunlight.
Are Plants Quantum?

A long-standing debate over just how “quantum” photosynthesis is may finally be coming to an end.
“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.
The Universe Might Be Too Thin, Scientists may have found a new crack in our understanding of the universe, reports The Atlantic and Quanta. The cosmos is starting to look a bit weird. For a few years now, cosmologists have been troubled by a discrepancy in how fast the universe is expanding. They know how fast it should be going, based on ancient light from the early universe, but apparently the modern universe has picked up too much speed—a clue that scientists might have overlooked one of the universe’s fundamental ingredients, or some aspect of how those ingredients stir together.
The Army is formally moving ahead with the development and fielding of a powered exoskeleton to help soldiers move faster and carry more while reducing overall fatigue after years of experimentation and testing.
Officials with Army Futures Command are currently in the process of drafting formal requirements for an infantry exoskeleton ahead of a defense industry day sometime in November, said Ted Maciuba, deputy director of the robotic requirements division for Army Futures Command.
Breaking Defense first reported news of the fresh exoskeleton effort.
Like Concrete
In simpler terms: the resulting material “feels like concrete but much lighter,” Fernandez told CNN. “Very light rock.”
“We have a route to… manufacturing buildings to tools from 3D printing to mold casting with just one single material,” he added.
The biotech company Moderna released a 135-page document on Thursday that spells out the details of how it is conducting the late-stage trial of its coronavirus vaccine.
The company hopes to earn the trust of the public and of scientists who have clamored for details of its study.
Is it possible to discover an asymmetry of a few thousandths of a millimeter on a neutron star 42 million billion km from Earth?
A new study suggests anticholinergic medications may increase the risk of accelerated cognitive decline, especially in older adults at high risk of developing Alzheimer’s disease.
Anticholinergic drugs block the action of acetylcholine, a chemical messenger that controls a range of automatic bodily functions and plays a vital role in memory and attention.
Doctors prescribe these drugs for a variety of conditions, including urinary incontinence, overactive bladder, chronic obstructive pulmonary disorder (COPD), seasonal allergies, and depression.
