Rachel Feltman: Completely happy September, listeners! Let’s lean into these new faculty yr vibes by studying a bit of one thing. For Scientific American’s Science Rapidly, I’m Rachel Feltman—and that is your weekly science information roundup.
First, some excellent news for anybody glued to their cellphone, which—I imply, when you’re not, congratulations, I assume. A brand new paper gives reassurance that cell telephones don’t offer you mind most cancers, which is nice, phew….
So, how did we get right here? Again in 2011, the World Well being Group’s most cancers analysis company categorised cell phone radiation as presumably carcinogenic. That is a class meaning there’s restricted proof that one thing might presumably increase most cancers danger, nevertheless it’s removed from definitive.

You understand what else falls into that class? So-called conventional Asian pickled greens. And pay attention, if consuming pickled daikon is how I’m going, so be it.
The purpose is that a number of research suggesting one thing may doubtlessly be carcinogenic can get one thing placed on this listing, and it doesn’t imply it’s time to throw the kimchi out with the bathwater. However unsurprisingly, the concept cell telephones may trigger most cancers was scary sufficient—and universally relevant sufficient as a result of, once more, we’re all glued to our telephones—for advocacy teams, headlines, and even some regulators to latch onto.
In a brand new evaluate led by the Australian Radiation Safety and Nuclear Security Company and commissioned by the WHO researchers sifted via about 5,100 research on the topic they usually discovered simply 63 that glad their standards for inclusion.
Once they checked out these, the researchers mentioned: there was no obvious hyperlink between cellphone use and mind and head cancers. We’ll must keep watch over issues as know-how evolves, after all, and the identical group is now exploring cancers much less clearly linkable to cellphone use, comparable to leukemia, to verify there’s no hyperlink there, both.
And naturally, telephones don’t have to offer you most cancers to be dangerous for you. Final week, Sweden’s public well being authority—which has a reputation I received’t even attempt to pronounce, you’re welcome—issued new suggestions on how mother and father ought to regulate display screen time, and the rules are harsh.
They are saying that youngsters beneath the age of two shouldn’t be uncovered to any screens in any respect, two to 5 yr olds ought to follow an hour or much less, and youths ought to max out at three hours a day, not together with faculty work.
That’s really not too completely different from the American Academy of Pediatrics’ tips, although the U.S. group grants that kids beneath two years outdated ought to have the ability to video chat with grownup supervision and says 18-to-24-month-olds can get pleasure from instructional programming within the presence of a caregiver.
Whereas these kinds of tips embody screens of every kind, internet-connected gadgets, and notably telephones, are sometimes the main target. Earlier this yr, a examine commissioned by the President of France concluded that no youngster beneath the age of 11 ought to have a cellphone of any variety, no child beneath the age of 13 ought to have a smartphone, and people 15 and older ought to solely be allowed on “moral” social media websites, slightly than profit-driven platforms comparable to TikTok and Snapchat.
That very same report mentioned that kids beneath three ought to be evaded screens if potential. In keeping with a translation by The Guardian, that’s to guard them from the “technique of capturing kids’s consideration, utilizing all types of cognitive bias to close kids away on their screens, management them, re-engage them and monetise them” and switch them into “merchandise.”

Talking of defending youngsters, Oregon’s newest measles outbreak is formally the state’s worst one in three a long time. Numbers are additionally rising nationwide, the place the Facilities for Illness Management and Prevention is reporting 236 instances to this point this yr in contrast with simply 59 instances in all of 2023.
Well being specialists say that falling vaccination charges are the clear and avoidable trigger. Non-medical vaccine exemption charges for kindergartners in Oregon have risen from about 1% to eight.8% since 2000. On the subject of measles particularly, as of the 2022-2023 faculty yr, the nationwide vaccination charge for kindergarteners was simply over 93%—that’s virtually 2 proportion factors decrease than the brink for herd immunity, which might assist stop the unfold of measles.

Measles is extremely contagious, and may trigger lifelong well being points and even loss of life. So ensure that your youngsters are vaccinated! Now’s the proper time to go get your flu shot, too—and when you haven’t had COVID in the previous few months, throw in that new booster in when you’re at it.
And now for one thing utterly completely different: As Welcome to Night time Vale’s Cecil Palmer as soon as mentioned, “There’s a skinny semantic line separating bizarre and delightful, and that line is roofed in jellyfish.” Lovely, troubling, fascinating, deeply unsettling: all of those adjectives might simply describe the invasive freshwater jellyfish multiplying in lakes, ponds and quarries in British Columbia, Canada, particularly as a result of the species is usually generally known as the “peach blossom jellyfish,” which is simply too cute. Like, actually, too cute for an invasive species. Come on–make them simpler to hate.
Final month, a paper within the Canadian Journal of Zoology predicted that local weather change will probably prolong this invader’s vary. It additionally confirmed that each one 100 jellyfish sampled shared the identical genetic materials—in different phrases, they’re basically clones fashioned from one single prolific polyp or polyp cluster. As one of many researchers defined, polyps are tiny and exhausting to identify, one of many researchers defined, which suggests there could possibly be ticking jellyfish timebombs lurking in lakes we haven’t even begun to fret about but.
The one upside is that these all-male clones received’t get the evolutionary advantages of sexual copy, which suggests they’ll be means much less more likely to adapt to new environments. These jellyfish have by no means been reported to sting people, most likely as a result of their stinging cells are designed to paralyze wee little zooplankton and appear unable to pierce human pores and skin. However there’s some concern that they could begin outcompeting native species, together with younger salmon, in the case of discovering meals.
Now I’ll offer you all a bit of area.

You’ll have seen headlines a couple of mysterious pulsing noise popping out of a speaker on the ill-fated Boeing Starliner spacecraft, which introduced astronauts Butch Wilmore and Suni Williams as much as the Worldwide Area Station however will not be bringing them again down.
Final week NASA confirmed that this was simply suggestions ensuing from the audio connection between Starliner and the area station. NASA emphasised that it is a widespread prevalence, precipitated no danger to the crew, and that it’s normal process for astronauts to report appears like this to mission management.
The subtext is unquestionably that NASA is aware of we’re all laser centered on the whole lot which may presumably be going flawed with Starliner, you realize, the spacecraft that definitely-did-not-strand two astronauts in area for months longer than supposed, and they want us to please discover one thing else to speak about.
However talking of Starliner, not less than one final time, NASA has formally began prepping to ship the spacecraft again to Earth with out a crew.
On the time of this recording, the area company hoped to see Starliner undock at 6:04 p.m. Japanese on Friday, September 6. Did it land in White Sands Area Harbor, New Mexico, about six hours later? Hopefully. However possibly the climate didn’t cooperate they usually needed to postpone, or one thing else went flawed.
I’m not going to make the podcast workforce work over the weekend for this, so it’s type of a Schrödinger’s Starliner state of affairs. (Additionally, that’s a joke, so please don’t electronic mail me explaining how this isn’t in any respect like Schrödinger’s cat. Electronic mail me about actually the rest–I might love to listen to from you.)
That’s all for this week’s information roundup. However when you want extra space–okay, fantastic–tune in once more on Friday for a dialog with somebody who’s really up there proper now. And within the meantime, we’ll be again on Wednesday with a take a look at how the occasions of 9/11 modified the sector of forensic science.
If you happen to’re loving this present–I get it, it’s fairly nice–so, do us a favor and go away a remark, a like a evaluate, a score, no matter, wherever you take heed to podcasts. You can even ship us questions, feedback and recommendations for matters you’d like us to cowl at ScienceQuickly@sciam.com.
