Rachel Feltman: Comfortable Monday, listeners! For Scientific American’s Science Shortly, I’m Rachel Feltman. Let’s kick off the week by catching up on some science information you may need missed.

Final Tuesday a U.S. Division of Well being and Human Companies committee launched a brand new draft report on alcohol. The evaluation of present knowledge tied only one drink a day to elevated danger of liver cirrhosis, oral most cancers and esophageal most cancers. The committee additionally discovered that alcohol use was related to a better danger of loss of life from seven varieties of most cancers. And this isn’t the primary time that the well being results of alcohol have made headlines in 2025: earlier this month Surgeon Common Vivek Murthy argued that alcoholic drinks ought to include most cancers warning labels.

The report did discover some counterintuitive connections, too: individuals who had one drink a day had a decrease danger of ischemic stroke than individuals who didn’t, and girls who consumed one, two or three drinks per day had a decrease danger of diabetes. However these obvious advantages are fickle. The decrease danger of ischemic stroke, for instance, can disappear if individuals even sometimes drink 4 or 5 servings in a single sitting. And ladies who consumed two alcoholic drinks per day could have had a decrease danger total of diabetes, however additionally they had considerably greater dangers of ischemic stroke and liver illness.

So the main points might sound form of complicated, however the takeaway is easy sufficient: you undoubtedly shouldn’t take up consuming as a method to enhance your well being or use supposed advantages you’ve examine to justify your consumption. The World Well being Group’s stance is that no degree of alcohol consumption is secure to your well being. In fact, all of us do loads of issues that aren’t, strictly talking, good for us. However judging by this new report, we should always attempt to be aware of how alcohol suits into the large image of our existence. There’ll little question be headlines sooner or later saying that, for instance, purple wine is nice for x, y or z, however these headlines actually by no means imply you must drink extra alcohol than you’re presently consuming.

In the meantime, final Wednesday the U.S. Meals and Drug Administration banned the usage of Purple Dye No. 3 in meals, drinks and ingested medicine. The dye, which is created from petroleum, was rejected to be used in cosmetics and topical medicine again in 1990 after lab testing on rodents confirmed it might have carcinogenic results in excessive doses. Meals producers may have till January 2027 to reformulate their merchandise with out Purple Dye No. 3, and corporations that make ingested medicine may have till January 2028.

Advocacy teams filed a petition for the FDA to ban Purple Dye No. 3 in 2022, and the company has concluded that the dye does violate one thing known as the Delaney Clause—part of the Meals, Drug and Beauty Act that retains the FDA from authorizing any additive proven to trigger most cancers in people or different animals. However we should always word that, in accordance with reporting from Stat Information, the mechanism by which the dye causes most cancers in male rats isn’t really relevant to people.

Feltman: In different public well being information, a workforce of greater than 50 specialists publishing within the Lancet Diabetes & Endocrinology journal argued final week that the present analysis of “obesity” is flawed. The usage of physique mass index, or BMI, as a determinant of well being has been on the chopping block for some time now, and these researchers suggest specializing in extra exact measurements of extra physique fats. They’re additionally suggesting that individuals who meet the definition for weight problems however who shouldn’t have any of the situations that may typically be related to greater weight, like diabetes or coronary heart illness, be put in a separate class from of us who’re already coping with these well being issues. The researchers say it will assist physicians present extra nuanced care, although it’s not likely clear how this could handle the prevailing subject of weight stigma in medication.

And now for some house. Final Wednesday a SpaceX Falcon 9 rocket launched with two new lunar landers in tow. The 2 landers had been created by two totally different personal corporations and had been launched into barely totally different orbits.

Feltman: One of many SUV-sized landers is from the Japanese startup ispace. The opposite comes from Texas-based Firefly Aerospace. Dubbed the Blue Ghost lunar lander, it’s carrying payloads for 10 totally different NASA experiments. Blue Ghost is predicted to achieve the lunar floor in about 45 days.

That wasn’t final week’s solely business house win. On Thursday morning Blue Origin’s New Glenn rocket launched for the very first time. The rocket’s higher stage made it into orbit, which made the launch technically successful. However Blue Origin didn’t fairly handle the additional credit score portion of their examination: they tried and didn’t land the rocket’s reusable booster on a ship ready within the Atlantic. However provided that New Glenn was initially alleged to take off again in 2020, this SpaceX competitor might be blissful to take the win.

Circling again to SpaceX, it wasn’t all sunshine and rainbows for them final week, both. On Thursday afternoon the corporate ran the seventh take a look at launch of its Starship automobile. The second stage of the megarocket, which was carrying a take a look at payload of mock satellites, exploded a couple of minutes after takeoff. In response to a social media put up by SpaceX founder Elon Musk, some form of leak was seemingly the offender, and the corporate plans to go forward with one other launch subsequent month.

We’ll wrap up with one thing fairly wild. Have you ever ever thought of spiders in Australia and been like, “Nah, that’s not big or venomous enough for me”? Effectively, scientists have gotten you coated.

Final Monday researchers introduced the invention of a brand new species of funnel-web spider. It’s an in depth relative of the Sydney funnel-web spider, which is understood for painful bites that may trigger critical sickness and even loss of life. This new species, which scientists have nicknamed “Big Boy,” can develop—you guessed it—nearly twice so long as different funnel-web spiders and it additionally has larger fangs and venom glands. So have enjoyable with that, Australia!
