Most clams are happy to make their burrow in a nice, soft bed of sand or mud. Not this mollusc. A recently uncovered relative of the shipworm puts the hard into hardcore, chewing holes into rocks and excreting the debris as sand.

Lithoredo abatanica joins a short list of freshwater animals capable of literally weathering the landscape and creating real estate for other species to hide in, while potentially affecting the course of their river ecosystem.

Only thing is, we don’t really know why it goes to these lengths.

An asteroid estimated to be around the size of the Great Pyramid of Giza may hit the Earth on May 6, 2022, according to the National Aeronautics and Space Administration (NASA).

Despite the one in 3,800 odds — a measly 0.026% chance — of the asteroid smashing into the Earth, the worst-case scenario will surely be of a scene akin to the climax of an apocalypse movie, or even worse, as per NASA via The Daily Express on Nov. 16.

If the “city-killer” asteroid, labeled JF1, is to hit Earth, the impact would be equivalent to the detonation of 230 kilotons of TNT. That is 15 times stronger than the atomic bomb that hit Hiroshima in 1945, which destroyed the whole city with 15 kilotons of force.

Rocket Lab is getting ready to fly its tenth mission, which the first official launch window during which it could happen set for this week on November 29. Aside from being a milestone 10th mission (dubbed ‘Running Out of Fingers,’ ha), this will be the first time that Rocket Lab includes technology designed to help it eventually recover and reuse elements of its launch vehicle.

After first designing its Electron launch platform as a fully expendable spacecraft, meaning it could only do one way trips to bring cargo to orbit, Rocket Lab announced that it would be moving towards rocket reusability at an event hosted by CEO and founder Peter Beck in August. To make this happen, the company will be developing and testing the tech necessary to recover Electron’s first-stage rocket booster over the course of multiple missions.

Toe be clear, this mission has the primary goal of delivering a number of small satellites on behalf of paying customers, including microsatellites from Alba Orbital and a Tokyo –based company called ALE that is using microsatellites to simulate particles from meteors. But Rocket Lab will also be testing recovery instrumentation loaddd on board the Electron vehicle, including guidance and navigation systems, as well as telemetry and flight computer hardware. This will be used to gather real-time data about the process of re-entry for Electron’s first stage, and Rocket Lab will also attempt to make use of a reaction control system to control the orientation of the booster as it re-enters.

LONDON (AP) — Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild.

In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central African Republic and Angola. Seven countries elsewhere in Africa have similar outbreaks and cases have been reported in Asia, including the two countries where polio remains endemic, Afghanistan and Pakistan.

In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks. All the current vaccine-derived polio cases have been sparked by a Type 2 virus contained in the vaccine. Type 2 wild virus was eliminated years ago.
