Exact Phoretic Interaction of Two Chemically Active Particles

Posted by in category: particle physics

We study the nonequilibrium interaction of two isotropic chemically active particles taking into account the exact near-field chemical interactions as well as hydrodynamic interactions. We identify regions in the parameter space wherein the dynamical system describing the two particles can have a fixed point—a phenomenon that cannot be captured under the far-field approximation. We find that, due to near-field effects, the particles may reach a stable equilibrium at a nonzero gap size or make a complex that can dissociate in the presence of sufficiently strong noise. We explicitly show that the near-field effects originate from a self-generated neighbor-reflected chemical gradient, similar to interactions of a self-propelling phoretic particle and a flat substrate.

NASA Science Live: Asteroid Close Approach

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

Have you heard about an asteroid close-approach happening on April 29? Asteroid 1998 OR2 poses no threat to our planet, but we can still learn a lot by studying it. Don’t miss a special Planetary Defense episode of NASA Science Live on Monday, April 27 at 3:00 p.m. EDT to learn how we find, track and monitor asteroids and near-Earth Objects.

WHO declines comment on remdesivir in COVID-19, hopes for best

Posted by in category: biotech/medical

The WHO just removed pre made criticism of Gilead’s drug from it’s website. It quoted a flawed Chinese study on the drug, yet somehow the criticism was posted on it’s website. The criticism of the drug has since been removed as data from the Chicago study had not even yet been released, and they recieved strong criticism for it. A group of influential people and organizations have been criticizing every treatment, while at the same time proposing vaccines that do not even exist. Every doctor signs an oath, and you can not just let people die for vested interests, as it is my belief that is what is happening. I could be wrong, so prove me wrong by stopping the deaths with effetive treatment and less disinformation that supports vested interests.


A top World Health Organization official declined comment on Wednesday on reports that Gilead Science’s remdesivir could help treat COVID-19, the respiratory disease caused by the novel coronavirus, but said that further data was needed.

Elon Musk says shelter-in-place orders during COVID-19 are ‘fascist’

Posted by in categories: biotech/medical, Elon Musk

Billionaire Rocket Scientist SpaceX CEO Elon Musk: “Give people back their goddamn freedom.”


Elon Musk called the shelter-in-place orders in the San Francisco Bay Area and throughout the US “fascist” actions that are stripping people of their freedom on a Tesla earnings call on Wednesday. Musk’s comments come after a torrent of criticism for remarks he made late Tuesday night on Twitter, in which the billionaire CEO echoed President Trump by writing in all caps, “Free America Now.

DARPA Names SEAKR Pit Boss Prime for Blackjack

Posted by in categories: engineering, military, robotics/AI, satellites

SEAKR Engineering, Inc. has been awarded as the prime contractor for Defense Advanced Research Projects Agency (DARPA) Pit Boss contract to further expand its contractual work supporting the Blackjack program. The award for Phase I Option II is part of a three-phase effort seeking on-orbit demonstration of full processing capability in a multi-satellite constellation. SEAKR was first awarded a DARPA Pit Boss contract in October 2019.

DARPA’s Blackjack program focuses on integrating commercial satellite technologies into a constellation of military satellites. As sole prime, SEAKR will continue developing it’s Pit Boss solution to support the Blackjack program’s mission as a next generation on-board processor.

SEAKR said the solution will leverage off-the-shelf electronics adapted through design implementation to function reliably in space. The company said this award validates its program success in seeking on-orbit demonstration of state-of-the-art processing capability incorporating autonomous operations, Artificial Intelligence (AI), machine learning techniques, and bridged terrestrial and on-orbit technologies.

The US government is helping get cash to private space companies, replacing frozen venture capital

Posted by in categories: biotech/medical, business, economics, finance, government, military

Investment in the fast-growing space industry was booming well into the first quarter of 2020 but private capital has largely frozen as the coronavirus pandemic strikes the U.S., leading both civil and military agencies to step up funding for corporate partners.

“We kicked into high gear as soon as it was apparent a lot of companies were not going to be able to conduct business as usual due to distancing requirements,” Mike Read, International Space Station business and economic development manager at NASA’s Johnson Space Center, told CNBC.

U.S. equity investment in space companies totaled $5.4 billion across 36 deals in the first quarter, according to a report Friday by NYC-based firm Space Capital. But the second quarter is likely to just see a fraction of that investment, according to Space Capital managing partner Chad Anderson, as deal flow in the U.S. will follow China’s path. Chinese investment in space was climbing by record amounts until the first quarter, when “activity in China was basically shut off,” Anderson said.

Pentagon’s DARPA Plans To Create COVID-19 ‘Temporary Vaccine’ Until Regular Vaccine Is Developed

Posted by in categories: biotech/medical, military

DARPA is working on a “temporary vaccine” that would serve as a “firebreak” that would provide immunity for several months until a regular vaccine is made available. The researchers used two different methods to manufacture and clone the most potent antibodies of coronavirus patient survivors. The.
