Surprise: Solar System „Force Field“ Shrinks Fast

(October 1, 2010)

It’s cold, dusty, and bereft of planets, but the outskirts of our solar system are anything but dull, according to increasing evidence from NASA’s Interstellar Boundary Explorer (IBEX) craft.

As charged particles flow out from the sun, they eventually bump up against interstellar medium—the relatively empty areas between stars. These interactions „inflate“ a protective bubble that shields Earth and the entire solar system from potentially harmful cosmic rays (solar system pictures).

The solar wind bubble that protects Earth has been mapped for the first time

Using data IBEX collected on ENAs as it charted just one 11-year solar cycle, the time between shifts in the sun’s magnetic field, researchers built a three-dimensional map of the entire heliosphere, which Reisenfeld says shields Earth and other planets from harmful radiation.

“Our Earth gets bombarded by cosmic rays, galactic cosmic rays all the time,” he says. These rays can subtly affect airplanes that fly near the poles, often on trips between Europe or Asia and the US.

Scientists say that to study other planet’s astrospheres, which is what heliospheres are called when they surround other stars, we must first understand our own.

So you got the vaccine. Can you still infect people? Pfizer is trying to find out.

Whether or not the vaccines stop “onward transmission” of the virus is likely to be a critical variable in determining how the pandemic plays out and how soon life goes back to normal. Right now, researchers say, their best guess is that vaccines will reduce transmission but may not prevent it entirely.

Life on Venus? Astronomers See a Signal in Its Clouds

(14.09.2020)

“This is an astonishing and ‘out of the blue’ finding,” said Sara Seager, a planetary scientist at the Massachusetts Institute of Technology and an author of the papers (one published in Nature Astronomy and another submitted to the journal Astrobiology). “It will definitely fuel more research into the possibilities for life in Venus’s atmosphere.”

Über Impfstoffe zur digitalen Identität?

Das Ziel sei eine personalisierte, portable, biometrisch verbundene digitale Identität, die auf Lebenszeit besteht. Gründungspartner sind u.a. Gates‘ Firma Microsoft, die von der BMGF mit hohen Summen finanzierte Impfallianz GAVI, die auch in die Berateraffäre der Bundeswehr verstrickte Unternehmensberatung Accenture sowie die Rockefeller Foundation, eine der größten Stiftungen der USA.

China’s CRISPR babies: Read exclusive excerpts from the unseen original research

He Jiankui’s manuscript shows how he ignored ethical and scientific norms in creating the gene-edited twins Lulu and Nana.

Pluto is undergoing global warming, researchers find

(09.10.2002)

Elliot said the new results have surprised the observers, who as recently as July thought that Pluto’s atmosphere may be cooling. (…)

Since 1989, for example, the sun’s position in Pluto’s sky has changed by more than the corresponding change on the Earth that causes the difference between winter and spring.

U.S. Firms Are Helping Build China’s Orwellian State

(19.3.2019) When a Dutch cybersecurity researcher disclosed last month that Chinese security contractor SenseNets left a massive facial recognition database tracking the movements of over 2.5 million people in China’s Xinjiang province unsecured on the internet, it briefly shone a spotlight on the alarming scope of the Chinese surveillance state.

But SenseNets is a symptom of a much larger phenomenon: Tech firms in the United States are lending expertise, reputational credence, and even technology to Chinese surveillance companies, wittingly or otherwise.

China: Überwachungsstaat „made in USA“

Denn wie die US-Fachzeitschrift „Foreign Policy“ („FP“) kürzlich berichtete, seien neben SenseNets auch etliche andere Technikfirmen einerseits mit den USA verbandelt, andererseits gerade in Xinjiang tätig. Zufall ist das keiner: Das Uigurengebiet dient quasi als Testgebiet für gesellschaftliche Kontrolle und Einschränkung durch den chinesischen Staatsapparat.
