For the first time ever, meat was created in space — but no animals were harmed in the making of this 3D bioprinted “space beef.”
Aleph Farms, an Israeli food company, announced today (Oct. 7) that its experiment aboard the International Space Station resulted in the first-ever lab-grown meat in space. The company focuses on growing cultivated beef steaks, or growing an entire piece of real, edible meat out of just a couple of cells, in this case, bovine cell spheroids, in a lab.
On the space station, the experiment involved growing a piece of meat by mimicking a cow’s natural muscle-tissue regeneration process. Aleph Farms collaborated with the Russian company 3D Bioprinting Solutions and two U.S.-based food companies to test this method in space.

On Sept. 26, the team established a proof of concept when the astronauts performing the test were able to produce a small piece of cow muscle tissue on the space station. The experiment took place inside of a 3D bioprinter developed by 3D Bioprinting Solutions. Bioprinting is a process in which biomaterials, like animal cells, are mixed with growth factors and the material “bioink,” and “printed” into a layered structure. In this case, the resulting structure is a piece of muscle tissue.
The “3D bioprinter is equipped with a magnetic force which aggregated the cells into one small-scaled tissue, which is what meat is constructed by,” Yoav Reisler, an external relations manager at Aleph Farms, told Space.com in an email.
But, while 3D bioprinting has been used and tested on Earth for things like producing cartilage tissue, it works a little differently in space. “Maturing of bioprinted organs and tissues in zero gravity proceeds much faster than in Earth gravity conditions. The tissue is being printed from all sides simultaneously, like making a snowball, while most other bioprinters create it layer by layer. On Earth, the cells always fall downward. In zero gravity, they hang in space and interfere only with each other. Layer by layer printing in gravity requires a support structure. Printing in zero gravity allows tissue to be created only with cell material, without any intermediate support,” Reisler added.

The reasoning behind Aleph Farm’s efforts to produce “slaughter-free meat in space,” as the company describes it, is because of climate change, according to a press release sent by the company to Space.com. Animal farming, as it is noted in the 2019 Intergovernmental Panel on Climate Change special report, with its requirement for huge amounts of water and energy, contributes in a significant way to climate change.
“Our planet is on fire and we have no other one today. Our primary goal is to make sure it remains the same blue planet we know also with our next generations,” Reisler said.
“In space, we don’t have 10,000 or 15,000 Liter (3962.58 Gallon) of water available to produce one Kg (2.205 Pound) of beef,” Didier Toubia, Co-Founder and CEO of Aleph Farms, said in the release. “This joint experiment marks a significant first step toward achieving our vision to ensure food security for generations to come, while preserving our natural resources.”
The company aims to build upon the success of this proof of concept experiment and, within a few years or so, make cultivated beef steaks available on Earth through “bio-farms” where they will grow this meat, Reisler added.
Elizabeth Warren has taken an attention-getting approach to attacking Facebook’s recent announcement that it won’t fact-check politicians’ posts. She’s running an ad on the social network that deliberately contains a falsehood.
“Breaking news: Mark Zuckerberg and Facebook just endorsed Donald Trump for re-election,” reads the ad, which Warren also tweeted out Saturday. The ad immediately corrects itself but says it’s making a point. “What Zuckerberg *has* done is given Trump free rein to lie on his platform,” it says, “and then pay Facebook gobs of money to push out their lies to American voters.”
Neither Facebook nor the White House immediately responded to a request for comment.
Late last month, Facebook said it exempts politicians from its third-party fact-checking process and that that’s been the policy for more than a year. The company treats speech from politicians “as newsworthy content that should, as a general rule, be seen and heard,” Facebook’s vice president of global affairs and communications, Nick Clegg, said at the time.
“We don’t believe … that it’s an appropriate role for us to referee political debates and prevent a politician’s speech from reaching its audience and being subject to public debate and scrutiny,” Clegg added.
Earlier this week, Facebook told Joe Biden’s presidential campaign that it wouldn’t remove an ad by Trump’s reelection campaign despite assertions that the ad contains misinformation about Biden. The 30-second video said Biden had threatened to withhold $1 billion from Ukraine unless officials there fired the prosecutor investigating a company that employed Biden’s son.
At the time, Tim Murtaugh, a spokesman for Trump’s campaign, said the ads were accurate. But Factcheck.org noted that while Biden did threaten to withhold US money from Ukraine, there’s no evidence he did this to help his son, which is what the Facebook ad implied. Factcheck.org also said there’s no evidence Biden’s son was ever under investigation and that Biden and the US weren’t alone in pressuring Ukraine to fire the prosecutor, who was widely seen as corrupt.
Responding to Facebook’s refusal to pull the ad, Biden spokesman T.J. Ducklo said at the time that “the spread of objectively false information to influence public opinion poisons the public discourse and chips away at our democracy. It is unacceptable for any social media company to knowingly allow deliberately misleading material to corrupt its platform.”
Warren has called for the breakup of Facebook and other big tech companies, saying in part that they wield too much influence. Other lawmakers have called for Facebook and rival platforms to be regulated as a way of addressing concerns about the spread of fake news, among other things.
A user got his revenge on the ransomware gang who encrypted his files by hacking their server and releasing the decryption keys for all other victims.
This happened earlier today and involved the Muhstik gang. Muhstik is a recent strain of ransomware that has been active since late September, according to reports [1, 2, 3].
This ransomware targets network-attached storage (NAS) devices made by Taiwanese hardware vendor QNAP. The gang behind the Muhstik ransomware is brute-forcing QNAP NAS devices that use weak passwords for the built-in phpMyAdmin service, according to a security advisory published by the company last week.
After gaining access to the phpMyAdmin installation, Muhstik operators encrypt users’ files and save a copy of the decryption keys on their command and control (C&C) server. QNAP files encrypted by Muhstik can be recognized by each file’s new “.muhstik” file extension.
Annoyed software dev hacks back
One of the gang’s victims was Tobias Frömel, a German software developer. Frömel was one of the victims who paid the ransom demand so he could regain access to his files.
However, after paying the ransom, Frömel also analyzed the ransomware, gained insight into how Muhstik operated, and then retrieved the crooks’ database from their server.
Besides releasing the decryption keys, the German developer also published a decrypter that all Muhstik victims can use to unlock their files. The decrypter is available on MEGA [VirusTotal scan], and usage instructions are avaiable on the Bleeping Computer forum.
In the meantime, Frömel has been busy notifying Muhstik victims on Twitter about the decrypter’s availability, advising users against paying the ransom.
Apple admits that it sends some user IP addresses to Tencent in the “About Safari & Privacy” section of its Safari settings which can be accessed on an iOS device by opening the Settings app and then selecting “Safari > About Privacy & Security.” Under the title “Fraudulent Website Warning,” Apple says:
“Before visiting a website, Safari may send information calculated from the website address to Google Safe Browsing and Tencent Safe Browsing to check if the website is fraudulent. These safe browsing providers may also log your IP address.”
The “Fraudulent Website Warning” setting is toggled on by default which means that unless iPhone or iPad users dive two levels deep into their settings and toggle it off, their IP addresses may be logged by Tencent or Google when they use the Safari browser. However, doing this makes browsing sessions less secure and leaves users vulnerable to accessing fraudulent websites.

Even if people install a third-party browser on their iOS device, viewing web pages inside apps still opens them in an integrated form of Safari called Safari View Controller instead of the third-party browser. Tapping links inside apps also opens them in Safari rather than a third-party browser. These behaviors that force people back into Safari make it difficult for people to avoid the Safari browser completely when using an iPhone or iPad.
