‘Ring of fire’ eclipse Oct. 14 will be practice run for total solar eclipse next year

Posted by in category: space

Scientists generally, said NSF’s Lisa Winter, will be able to view a very active corona — or upper atmosphere of the sun — during the precious minutes that the sun is nearly completely blocked by the moon. The sun is nearing its maximum of solar activity in its 11-year-cycle, unlike the last U.S. total solar eclipse of 2017, meaning that “the corona will be very active this time around,” said Winter, who is NSF’s program director for solar-terrestrial research.

Solar activity has an immense impact on the ionosphere, which is a layer of Earth’s atmosphere that interacts with electromagnetic radiation from above and below its extent. These interactions affect the propagation of radio signals.

Neuroscientists’ long-term memory discovery might help dementia research

Posted by in categories: biotech/medical, neuroscience

Neuroscientists in New York have made a major breakthrough in memory research that promises to revolutionize our understanding of neurodegenerative diseases like Alzheimer’s.

A new study details how a structural cell that wraps around blood vessels may actually play an important role in the formation and storage of long-term memories.

According to the U.S Centers for Disease Control and Prevention, roughly 5.8 million American adults live with Alzheimer’s disease and other related dementias. And yet, our understanding of these diseases is still fairly limited, largely thanks to question marks over how memories are actually formed.

New research may make future design of nanotechnology safer with fewer side effects

Posted by in categories: biotech/medical, nanotechnology

A new study, published in Nature Nanotechnology, may offer a strategy that mitigates negative side effects associated with intravenous injection of nanoparticles commonly used in medicine.

“Nanotechnology’s main advantage over conventional medical treatments is its ability to more precisely target tissues, such as targeted by chemotherapy. However, when nanoparticles are injected, they can activate part of the called complement,” said senior author Dmitri Simberg, Ph.D., professor of Nanomedicine and Nanosafety at the University of Colorado Skaggs School of Pharmacy on the University of Colorado Anschutz Medical Campus.

Complement is a group of proteins in the immune system that recognize and neutralize bacteria and viruses, including nanoparticles which are foreign to the body. As a result, nanoparticles are attacked by triggering side effects that include shortness of breath, elevated heart rate, fever, hypotension, and, in rare cases, anaphylactic shock.

Natural genetically modified crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors

Posted by in categories: biotech/medical, food, genetics

Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.

Research, led by the University of Sheffield, is the first to show the frequency at which grasses incorporate DNA from other species into their genomes through a process known as lateral gene transfer.

The stolen genetic secrets give them an by allowing them to grow faster, bigger or stronger and adapt to new environments quicker.

“The Universe Came From a Black Hole” String Theory Founder Reveals James Webb Telescope’s New Image. Deep within dense star clusters, something extraordinary dwells: Stars. But these, are no ordinary stars, but colossal celestial beings, known as supermassive stars. And now, their existence has been unveiled by the piercing gaze of the James Webb Space Telescope.

According to the standard model of cosmology, after the universe came out of the big bang, it took between 500 million to 1 billion years for the first stars to form. That however, is changing.

Consciousness: The sense that you are experiencing something—

Posted by in category: neuroscience

That, in a nutshell, is The perceived sensation of pain that you know as heartburn, the smell that draws you to a steak on the grill, the sight of magenta streaked across the sky at sunset—all are instances of conscious experience.

New kind of quantum computer made using high-resolution microscope

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

Physicists have performed the first quantum calculations to be carried out using individual atoms sitting on a surface.

The technique, described on 5 October in Science1, controls titanium atoms by beaming microwave signals from the tip of a scanning tunnelling microscope (STM). It is unlikely to compete any time soon with the leading approaches to quantum computing, including those adopted by Google and IBM, as well as by many start-up companies. But the tactic could be used to study quantum properties in a variety of other chemical elements or even molecules, say the researchers who developed it.

At some level, everything in nature is quantum and can, in principle, perform quantum computations. The hard part is to isolate quantum states called qubits — the quantum equivalent of the memory bits in a classical computer — from environmental disturbances, and to control them finely enough for such calculations to be achieved.
