The U.S. Food and Drug Administration (FDS) is alerting customers to an “urgent” nationwide blueberry recall. The organization announced in a July 14 notice that certain pouches of Natierra Organic Freeze-Dried Blueberrie are being recalled due to possible lead contamination. The recall was voluntarily issued by BrandStorm Inc.

The recall involves two lots of blueberries, both of which were packaged in 1.2-ounce pack sizes and distributed in the United States through retail and online stores services. Recalled Lot 2021363–1 features a best-by date of “12÷2024” and UPC 812907011160. The second recalled lot number is 2022026–1, with a best-by date of “01÷2025” and UPC 812907011160. The recalled Natierra Organic Freeze-Dried Blueberries were sold in a white and blue pouch with Natierra brand and Logo, with an image available here.

The company issued the recall after testing conducted by a lab in Maryland identified the presence or potential presence of lead above the FDA’s recommended limits. Per the release, “an investigation was conducted by the packing site. The original heavy metal reports received for the crop year showed no presence of lead and-or cause for batch testing. After further investigation it was found that the products county of Origin is Lithuania and aggressive monitoring of heavy metals may be deemed necessary.” Although lead, a toxic substance, is constantly present in small amounts and people are exposed to it daily, exposure to large amounts can lead to lead positing. According to the Mayo Clinic, signs and symptoms of lead poisoning include joint and muscle pain, headache, abdominal pain, and mood disorders, among others. However, symptoms typically don’t appear until dangerous amounts have accumulated. Infants, young children, and a developing fetus can experience more severe symptoms.

In November last year, an undercover agent with the FBI was inside a group on Amazon-owned messaging app Wickr, with a name referencing young girls. The group was devoted to sharing child sexual abuse material (CSAM) within the protection of the encrypted app, which is also used by the U.S. government, journalists and activists for private communications. Encryption makes it almost impossible for law enforcement to intercept messages sent over Wickr, but this agent had found a way to infiltrate the chat, where they could start piecing together who was sharing the material.

As part of the investigation into the members of this Wickr group, the FBI used a previously unreported search warrant method to force one member to unlock the encrypted messaging app using his face. The FBI has previously forced users to unlock an iPhone with Face ID, but this search warrant, obtained by Forbes, represents the first known public record of a U.S. law enforcement agency getting a judge’s permission to unlock an encrypted messaging app with someone’s biometrics.

According to the warrant, the FBI first tracked down the suspect by sending a request for information, via an unnamed foreign law enforcement partner, to the cloud storage provider hosting the illegal images. That gave them the Gmail address the FBI said belonged to Christopher Terry, a 53-year-old Knoxville, Tennessee resident, who had prior convictions for possession of child exploitation material. It also provided IP addresses used to create the links to the CSAM. From there, investigators asked Google and Comcast via administrative subpoenas (data requests that don’t have the same level of legal requirements as search warrants) for more identifying information that helped them track down Terry and raid his home.

Google’s Threat Analysis Group (TAG), whose primary goal is to defend Google users from state-sponsored attacks, said today that Russian-backed threat groups are still focusing their attacks on Ukrainian organizations.

In a report regarding recent cyber activity in Eastern Europe, Google TAG security engineer Billy Leonard revealed that hackers part of the Turla Russian APT group have also been spotted deploying their first Android malware.

They camouflaged it as a DDoS attack tool and hosted it on cyberazov[.]com, a domain spoofing the Ukrainian Azov Regiment.

Just days after the first formal release of its first show-off images scientists using the new James Webb Space Telescope (JWST) have posted some stunning new images of two spiral galaxies.

Posted on Flickr by Judy Schmidt working on the PHANGS Survey, the stunning image, above, shows the spectacular “Phantom Galaxy” (also called M74 and NGC 628), with others (scroll down) showing another spiral galaxy called NGC 7496.

The incredible new images are testament to Webb’s skill at seeing in infrared and thus seeing through the gas and dust that obscures a lot of what is going on in some of the most arresting objects in the night sky.

A team of astronomers using the Chinese Insight-HXMT x-ray telescope have made a direct measurement of the strongest magnetic field in the known universe. The magnetic field belongs to a magnetar currently in the process of cannibalizing an orbiting companion.

Magnetars are nasty, but thankfully rare. They are a special kind of neutron star that power up the strongest known magnetic fields.

Astronomers don’t know the exact origins of these ultra-powerful fields, but as usual they have their suspicions. While neutron stars are made of almost entirely neutrons, they do contain small populations of protons and electrons. When neutron stars are born in supernova explosions of a massive star, those charged particles can briefly create a strong magnetic field. In normal neutron stars, the magnetic field quickly melts away from all the complex physics happening in the explosion. But for some neutron stars, the magnetic field locks itself in before that happens. When the neutron star finally reveals itself, it retains this impressive magnetic strength, and a magnetar is born.

New electrocatalysis electrodes have been created that are simpler and cheaper than conventional ones, and can substantially increase the efficiency of water splitting. Decorated with chiral molecules like helicenes, these devices double the activity of the oxygen evolution reaction, the bottleneck of the process, and improve its selectivity.

‘With electrocatalysis, we [can] use electrons from renewable sources [like solar and wind] to produce clean chemicals and fuels,’ explains Magalí Lingenfelder from the Max Planck–EPFL laboratory for molecular nanoscience and technology, in Switzerland, who led the study. In this work, her team focused on the oxygen evolution reaction. ‘It’s the bottleneck of water splitting,’ she says. ‘We wanted to increase its performance with cheap, simple solutions.’

EPFL researchers have shown that people’s perception of office temperature can vary considerably. Personalized climate control could therefore help enhance workers’ comfort—and save energy at the same time.

Global warming means that heatwaves are becoming ever-more frequent. At the same time, we’re in a global race against the clock to reduce buildings’ energy use and carbon footprint by 2050. This has shone the spotlight on the importance of making the thermal comfort of buildings a strategic and economic priority. And this is the focus of research conducted by Dolaana Khovalyg, a tenure track assistant professor at EPFL’s School of Architecture, Civil and Environmental Engineering (ENAC) and head of the Laboratory of Integrated Comfort Engineering (ICE), which is linked to the Smart Living Lab in Fribourg.

In her latest study, published as a brief, cutting-edge report in the journal Obesity, she highlights the benefits of providing personalized thermal conditioning and heating for each office desk, rather than maintaining a standard temperature throughout an open space. Khovalyg and her team came to this conclusion after the human thermo-physiological data they collected showed that individuals display very different levels of thermal comfort under normal office conditions.

It’s a basic rule of chemistry and physics: when you heat things up, they get bigger. While there are exceptions (like water and ice), it’s difficult to find a material with zero thermal expansion.

But new research from the University of New South Wales and the Australian Nuclear Science and Technology Organisation has found a compound that doesn’t thermally expand – at least, not between −269°C and 1126°C.

The researchers examined a substance made from scandium, aluminium, tungsten and oxygen (Sc1.5 Al0.5 W3 O12), bonded together in a crystalline structure.
