Research identifies detection constraints for dark photons

Posted by in categories: cosmology, particle physics

:oooo.


Past cosmological and astrophysical observations suggest that over one quarter of the universe’s energy density is made up of a non-conventional type of matter known as dark matter. This type of matter is believed to be composed of particles that do not absorb, emit or reflect light, and thus cannot be observed directly using conventional detection methods.

Researchers worldwide have carried out studies aimed at detecting dark matter in the universe, yet so far, none of them has been successful. Even the for dark matter, weakly interacting massive particles (WIMPs), have not yet been observed experimentally.

At Least 70 Coronavirus Vaccines Are Already in Development, WHO Report Shows

Posted by in categories: biotech/medical, health

At least 70 potential coronavirus vaccines are currently in development, with 3 already in clinical trials, according to the World Health Organisation.

WHO published an updated list of vaccine efforts on April 11, showing a vast array of companies pursuing shots that could halt the coronavirus. Bloomberg News reported on the document earlier.

As the virus continues to spread, infecting more than 1.9 million people and killing more than 110,000 worldwide, researchers have been racing to develop vaccines.

Get ready for all-electric flying car races, they’re coming

Posted by in categories: economics, transportation

The Airspeeder vehicle, which weighs about 550 pounds, uses a battery pack that can be swapped out during the race. The packs are expected to last for about 15 minutes. Four 32-horsepower electric motors propel the cars to a top speed of about 125 miles per hour. The vehicle tears through the air between about 15 and 130 feet off the ground.

Matt Pearson, founder of Alauda and the Airspeeder series, said:

:oooooo.


A technique developed by Purdue University scientists could allow doorknobs and other metal surfaces to be modified in a way that would kill bacteria on contact.

‘Longest animal ever’ discovered in deep-sea canyon off Australian coast

Posted by in category: futurism

Underwater explorers found a 150-foot-long (45 meters) siphonophore — a translucent, stringy creature that, like coral, is made up of smaller critters — living in a submarine canyon off the coast of Australia. It’s “seemingly the largest animal ever discovered,” they said.

Every individual siphonophore is made up of many little “zooids,” which each live lives that are more similar to animals we’re used to talking about, albeit always connected to the larger colony. Zooids are born axsexually, and each one performs a function for the siphonophore’s larger body, according to a research article published in the journal Developmental Dynamics in 2005. Linked together in long chains, the colonies were already known to reach lengths of up to 130 feet (40 m) according to the Monterey Bay Aquarium — though each siphonophore is only about as thick as a broomstick.

The new, record-setting siphonophore was one of several discoveries made by a team aboard the research vessel Falkor while exploring deep-sea canyons near Australia’s Ningaloo Coast.

Switching on a key cancer gene could provide first curative treatment for heart disease

Posted by in category: biotech/medical

This is huge news… heart disease is the number one killer globally.

“They found that Myc-driven activity in heart muscle cells is critically dependent on the level of another protein called Cyclin T1, made by a gene called Ccnt1, within the cells. When the Ccnt1 and Myc genes are expressed together, the heart switches into a regenerative state and its cells start to replicate. The results are published today in the journal Nature Communications.”


Researchers trying to turn off a gene that allows cancers to spread have made a surprising U-turn. By making the gene overactive and functional in the hearts of mice, they have triggered heart cell regeneration. Since adult hearts cannot usually repair themselves once damaged, harnessing the power of this gene represents major progress towards the first curative treatment for heart disease.

Hyperbaric Application to COVID-19 Pulmonary Infection

Posted by in category: biotech/medical

In the midst of the coronavirus epidemic/pandemic it bears remembering the application of hyperbaric oxygen therapy to the last major pandemic that impacted the United States in 1918, the Spanish Flu Pandemic. Death was primarily by pulmonary infection and its attendant hypoxemia and respiratory failure. The first application of hyperbaric medicine to a Spanish Flu victim was likely also the first application to a human being in the United States. In 1918 Dr. Orval Cunningham of Kansas City was brought a dying friend of a fellow physician. The patient was moribund and blue. Before Cunningham could perform his planned animal experiments he was asked to treat this dying patient. With just a one-hour treatment with compressed air at 1.68 atmospheres absolute the patient experienced improvement. Combined with additional hyperbaric treatments over the next 3 days this patient’s life was saved. Others followed.

Today’s coronavirus’ mortality is due to pulmonary infection and respiratory failure. While there are differences between the Spanish Flu and coronavirus the primary pathology is in the lungs, the first organ of contact with hyperbaric therapy beyond the skin. The ability of hyperbaric oxygen to penetrate inflammatory pulmonary secretions allows adequate oxygen to reach the blood while inhibiting the inflammatory process. Applied correctly, hyperbaric therapy may have utility in coronavirus patients similar to its life-saving history with the Spanish Flu. Harch Hyperbarics Inc 504 309‑4948 www.hbot.com

Doctors Suspect Mystery COVID-19 Lung Problems, Plea for New Approach

Posted by in category: biotech/medical

Some doctors are questioning the way ventilators are being used for people with serious cases of COVID-19. Why? More data shows a high death rate for patients treated under current ventilator practices.

At the same time, these doctors are saying their patients behave more like they have high altitude sickness than a viral infection. They talk about two different types of COVID-19 patients with differing severe lung problems.

While some patients respond to treatment as expected, doctors also describe patients whose lungs seem relatively fine, but who still can’t get enough oxygen into their blood. These patients may make up the majority with severe infections.

Neuroscientists find memory cells that help us interpret new situations

Posted by in category: neuroscience

Neuroscientists at MIT have now identified types of cells that encode distinctive segments of an overall experience — a memory. The brain stores these chunks of memory in the hippocampus They are activated whenever a similar experience takes place, and are distinct from the code that stores detailed memories of a specific location.
