Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

‘Unprecedented risk’ to life on Earth: Scientists call for halt on ‘mirror life’ microbe research (www.theguardian.com)

submitted 4 days ago by MicroWave to c/world

73 comments fedilink hide all child comments

Summary

Leading scientists, including Nobel laureates, are urging a halt to research on creating “mirror life” microbes, citing “unprecedented risks” to life on Earth.

Mirror microbes, built from reversed molecular structures, could evade natural immune systems, leading to uncontrollable lethal infections.

While mirror molecules hold potential for medical and industrial uses, researchers warn that mirror organisms could escape containment and resist antibiotics.

A 299-page report in Science advocates banning such research until safety can be ensured and calls for global debate on its ethical and ecological implications.

Regardless of whether such an organism is a danger, there's no way we can even come close to creating an entire organism with an opposite chirality in just a decade. That would require somehow synthesizing every chiral component of the organism (proteins, enzymes, DNA, etc) from scratch which is completely impossible with current or near future technology.

I've been out of synthetic bio for damn near two decades now, and an undergrad when was I even in it, but I'm not so sure. PCR didn't come around until 85. I had professors that used to do every cycle manually. Human genome project wrapped in 03(?). You can order custom oligos for like $0.13USD a base pair mail order now. You type it in on a webform, a machine creates a custom molecule for you, and if you want to pay a little extra you can have it over-night. I suppose it depends what you call "near future", and synthetic biology has always had moving goal posts when it came to "functional liposome" and "synthetic life", but I don't know... shit can move fast sometimes.
