The derecho in the U.S. East on June 3, 2020, killed 4 people and left a million without power. A Colorado derecho on June 6 had winds in excess of 100 mph. Europe, Asia and South America also have derechos. Here’s what scientists know about them. Source: https://earthsky.org/earth/what-is-a-derecho-storm-system…

A fresh twist in chiral topology
The concept of chirality is well-established in science: when an object cannot be superimposed on its mirror image, both the object and its mirror image are called chiral. In the drug industry, for instance, more than 50% of the pharmaceutically active molecules used nowadays are chiral molecules. While one of the ‘enantiomers’ is life-saving, its counterpart with opposite handedness may be…
K2-25: An eccentric hot Neptune with the mass of seven Earths
Of the roughly 4,300 exoplanets confirmed to date, about ten percent of them are classified as “hot Jupiters.” These are planets with masses between about 0.4 and 12 Jupiter-masses and orbital periods less than about 110 days (implying that they orbit close to their star—usually much closer than Mercury is to the Sun—and have hot surface temperatures). A “hot Neptune” has…
Academics Turn PC Power Units Into Speakers To Leak Secrets From Air-Gapped Systems
Academics from an Israeli university have published new research last week showing how an attacker could turn a computer’s power supply unit into a rudimentary speaker that can secretly transmit data from an infected host using audio waves. From a report: The technique, named POWER-SUPPLaY, is the work of Mordechai Guri, the head of R&D at the Ben-Gurion University of the…
Image: Hubble gazes at fluffy-looking galaxy
This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice’s Hair), NGC 4237 is classified as a flocculent spiral galaxy. This means that its spiral arms are not clearly distinguishable from each other, as in “grand design” spiral galaxies, but are instead patchy…
White House Told Federal Health Agency To Classify Coronavirus Deliberations
The White House has ordered federal health officials to treat top-level coronavirus meetings as classified, an unusual step that has restricted information and hampered the U.S. government’s response to the contagion, Reuters is reporting, citing four Trump administration officials. From the report: The officials said that dozens of classified discussions about such topics as the scope of infections, quarantines and travel…
Split Verdict Given For CIA Programmer Charged In Massive Leak
An anonymous reader quotes a report from The Wall Street Journal: A federal jury couldn’t reach a verdict on whether a former software engineer for the Central Intelligence Agency was responsible for leaking a trove of classified documents to WikiLeaks, convicting him instead on lesser charges stemming from the leak (Warning: source paywalled; alternative source). Joshua Schulte, 31 years old, was…
Here’s how to see that huge asteroid that’ll safely pass Earth in April
The huge asteroid known as (52768) 1998 OR2 will pass closest on April 29, 2020. Observers peering through telescopes will see it as a slow-moving “star.” Charts, tips – plus how to watch online – here. Source: https://earthsky.org/astronomy-essentials/asteroid-52768-1998-or2-april-2020-how-to-see…
ACLU Sues To End ICE’s Rigged Algorithms That Keep Immigrants In Jail
A new lawsuit filed by the New York Civil Liberties Union and Bronx Defenders alleges that U.S. Immigration and Customs Enforcement uses a rigged algorithm to detain virtually everyone ICE’s New York Field Office brings in, even when the government itself believes they present a minimal threat to public safety. The Intercept reports: The suit, which asks that ICE’s “Risk Classification…
Could K2-18b be habitable after all?
A new study by researchers at Cambridge University suggests that the giant exoplanet K2-18b – a mini-Neptune – may be more potentially habitable than previously thought. Source: https://earthsky.org/space/k2-18b-mini-neptune-exoplanets-habitability…
