Too Much Salt Suppresses Phagocytes

Posted by in category: biotech/medical

Summary: Too much salt can disrupt the energy balance of immune cells and prevent them from functioning correctly.

Source: MDC

For many of us, adding salt to a meal is a perfectly normal thing to do. We don’t really think about it. But actually, we should. As well as raising our blood pressure, too much salt can severely disrupt the energy balance in immune cells and stop them from working properly.

New Directed Energy Device for Biomedical and Military Defense Applications

Posted by in categories: biotech/medical, military

An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications.

The Purdue invention uses composite-based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. The interest in NLTLs has increased in the past few decades because they offer an effective solid-state alternative to conventional vacuum-based, high-power microwave generators that require large and expensive external systems, such as cryogenic electromagnets and high-voltage nanosecond pulse generators.

NLTLs have proven effective for applications in the defense and biomedical fields. They create directed high-power microwaves that can be used to disrupt or destroy adversary electronic equipment at a distance. The same technology also can be used for biomedical devices for sterilization and noninvasive medical treatments.

In a NASA simulation of an asteroid impact, scientists concluded they couldn’t stop a space rock from decimating Europe

Posted by in categories: asteroid/comet impacts, existential risks

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.

A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.

These meteorites landed on Earth after a 22-million-year voyage

Posted by in category: space

For the first time, scientists have been able to precisely map the flight path of an asteroid that landed on Earth and trace it back to its point of origin. The boulder-size fragment’s journey to our planet began 22 million years ago, according to new research.

The asteroid, known as 2018 LA, appeared like a fireball in the skies over Botswana on June 2, 2018, before breaking apart and landing in the Central Kalahari Game Reserve.

Prior to breaking up in Earth’s atmosphere, scientists determined that the asteroid was about 5 feet (1.7 meters) in diameter, weighed 12566 pounds and had been traveling at 37282 miles per hour.

Solar Wind Traveling 1,118,468 mph Due to Hit Earth Sunday

Posted by in category: futurism

Just days after Earth was hit by a coronal mass ejection (CME), it appears another blast of solar wind is due to impact Earth on Sunday; it is currently traveling at a brisk 1118, 468 mph towards the planet.

A minor G1-class Geomagnetic Storm is possible late Saturday into much of Sunday as the solar wind interacts with the Earth’s magnetic field. While the National Weather Service’s Space Weather Prediction Center has not issued any advisory for this solar wind yet, a watch or warning could be posted tomorrow for this event.

Hydroxyl Molecule Signature Detected in an Exoplanet Atmosphere for the First Time

Posted by in categories: alien life, chemistry, sustainability

An international collaboration of astronomers led by a researcher from the Astrobiology Center and Queen’s University Belfast, and including researchers from Trinity, has detected a new chemical signature in the atmosphere of an extrasolar planet (a planet that orbits a star other than our Sun).

Crew-1 Mission | Return

Posted by in categories: robotics/AI, space travel

SpaceX and NASA are targeting Saturday, May 1 at 8:35 p.m. EDT, or 00:35 UTC on May 2, for Dragon to autonomously undock from the International Space Station (ISS) and splashdown off the coast of Florida on Sunday, May 2 at approximately 2:57 a.m. EDT, 6:57 UTC, completing its first six-month operational mission to the Station.

A series of departure burns will move Dragon away from the orbiting laboratory, followed by the vehicle jettisoning the trunk to reduce weight and mass to help save propellant for the deorbit burn. Once complete, Dragon will re-enter Earth’s atmosphere and deploy its two drogue and four main parachutes in preparation for a soft water landing.

Targeting tumors with nanoworms

Posted by in categories: bioengineering, biotech/medical, chemistry, nanotechnology, supercomputing

Getting closer.


Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.

“A lot of medicines involve intravenous injections of drug carriers,” said Ying Li, an assistant professor of mechanical engineering at the University of Connecticut. “We want them to be able to circulate and find the right place at the right time and to release the right amount of drugs to safely protect us. If you make mistakes, there can be terrible side effects.”
