A now-patched high-severity security vulnerability in WhatApp’s image filter feature could have been abused to send a malicious image over the messaging app to read sensitive information from the app’s memory.
Tracked as CVE-2020–1910 (CVSS score: 7.8), the flaw concerns an out-of-bounds read/write and stems from applying specific image filters to a rogue image and sending the altered image to an unwitting recipient, thereby enabling an attacker to access valuable data stored the app’s memory.

Engineers are set to test a device that could pull defunct spacecraft and used rocket parts back to Earth, allowing them to burn up harmlessly in the atmosphere.
Researchers at Purdue University in West Lafayette, Indiana, are launching a prototype drag sail Thursday aboard a rocket made by Firefly Aerospace, a private space company based in Austin, Texas. The mission is designed to assess how well the kitelike sail can de-orbit the rocket’s spent upper stage.
The launch is scheduled to take place at the Vandenberg Space Force Base in California between 6 p.m. and 10 p.m. PT.
Cats have many superior genetic mutations like night vision even immunity to the current pandemic. If we can find the key to their immunity we could find a way to have near super human immunity.
“Getting a better understanding of the cat’s biology and genetic makeup will help us better understand the biology of humans, too,” says Leslie Lyons. (Credit: Lottie/Flickr)
The findings, published in Trends in Genetics, come after decades of genome DNA sequencing by Leslie Lyons, professor of comparative medicine in the University of Missouri College of Veterinary Medicine. Their cat genome assembly is nearly 100% complete.
In a new review article in Nature Photonics, scientists from Los Alamos National Laboratory assess the status of research into colloidal quantum dot lasers with a focus on prospective electrically pumped devices, or laser diodes. The review analyzes the challenges for realizing lasing with electrical excitation, discusses approaches to overcome them, and surveys recent advances toward this objective.
“Colloidal quantum dot lasers have tremendous potential in a range of applications, including integrated optical circuits, wearable technologies, lab-on-a-chip devices, and advanced medical imaging and diagnostics,” said Victor Klimov, a senior researcher in the Chemistry division at Los Alamos and lead author of the cover article in Nature Photonics. “These solution-processed quantum dot laser diodes present unique challenges, which we’re making good progress in overcoming.”
Heeyoung Jung and Namyoung Ahn, also of Los Alamos’ Chemistry division, are coauthors.
The Research Brief is a short take about interesting academic work.
The big idea
Many small animals grow their teeth, claws and other “tools” out of materials that are filled with zinc, bromine and manganese, reaching up to 20% of the material’s weight. My colleagues and I call these “heavy element biomaterials,” and in a new paper, we suggest that these materials make it possible for animals to grow scalpel-sharp and precisely shaped tools that are resistant to breaking, deformation and wear.
😗 😁 Runs on the water it is surrounded by and solar.
The Aquon One is a luxury solar – hydrogen yacht completely powered by rooftop panels that generate electricity to run its twin 100kW motors and also create hydrogen for fuel cells from the water the boat sails through.
The system is similar to that of the zero emission Energy Observer research vessel which is sailing around the world on solar, wind and hydrogen power and is currently in French Guiana on its way from France to Japan. The difference being that the Aquon is not a research ship, but the world’s first leisure catamaran powered by green (no fossil fuels involved) hydrogen.
The company behind the yacht is Swiss Sustainable Yachts (SSY), formed in2018by Dr. Adrian Beer, a passionate yachtsman and serial entrepreneur who also founded and is CEO of the GrupoBeer corporation which advises and assists companies recovering from natural disasters.
