I have nothing to say

It can almost certainly tell different species apart based on the shape of those air bladders. And it can tell if a fish has something weird inside it, like a metal hook. In Hawaii, false killer whales often pluck tuna off fishing lines, and “they’ll know where the hook is inside that fish,” Aude Pacini, who studies these animals, tells me. “They can ‘see’ things that you and I would never consider unless we had an X-ray machine or an MRI scanner.”

This penetrating perception is so unusual that scientists have barely begun to consider its implications. The beaked whales, for example, are odontocetes that look dolphin-esque on the outside—but on the inside, their skulls bear a strange assortment of crests, ridges, and bumps, many of which are only found in males.

Pavel Gol’din has suggested that these structures might be the equivalent of deer antlers—showy ornaments that are used to attract mates. Such ornaments would normally protrude from the body in a visible and conspicuous way, but that’s unnecessary for animals that are living medical scanners.’

I'm not sure if I ever shared this story before here, but in Curacao, when I was allowed to assist in a guest interaction programme, there was suddenly consternation in the pool behind us. A guest had entered the water and the dolphins were going crazy, paying no heed to the trainers anymore. The lead trainer that was with me gave the dolphins to me to watch over while she went to help. When she came back she told me what had happened. The guest that had caused so much uproar had left the water again and was asked if he had done anything to upset the dolphins. He hadn't, and he couldn't imagine what was wrong... until he mentioned he had a pacemaker. The younger dolphins in the pool had never seen someone with a pacemaker before and apparently it rocked their world.

Moon Joy June artists!  This is the second week of Moon Joy June, and the prompt is “Moon.” If you’re an artist looking for some inspiration, we have a treat for you: four new and previously unseen images from our Artemis II mission!

All four of these images were captured on April 6, 2026, during flight day 6 of the mission, when the four astronauts aboard the Orion spacecraft conducted the lunar flyby of their ten-day journey. During the lunar flyby, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen captured photographs and collected scientific observations of the Moon in meticulous detail.

this is not life-threatening, but also who wants weeks of diarrhea and a fucking parasite in them lol. if you suspect you've already had this and it's passed, i would see a doctor. you might need an antiparasitic anyway. if you're actively sick, see a doctor and they might be able to prescribe medication to help you get over it faster.

try to avoid eating raw vegetables, scrub fruit with a produce brush and rinse thoroughly with water. again, don't bother with premade greens or bagged salads. if you buy lettuce, remove the outer 2-3 layers of leaves.

Only high temperatures will kill cyclospora. It resides in what is like a shell, which is highly resistant to water and most cleaning chemicals. The substance it uses to cling to food is so strong we don't even fully know what its limits are. It may be best to avoid fruits and veggies you can't cook. Scrubbing only works if done hard enough and on foods with no hiding places (Like cucumbers and grapes). Peeling the skin off is your best bet at avoiding it however, scrubbing is not guaranteed.

It is treatable by antibiotics such as sulfamethoxazole or trimethoprim unless you are allergic to sulfa drugs (or have other conditions) then treatment is by ciprofloxacin or nitazoxanide.

As usual, prevention is key:

Washing your hands with soap and water after using the bathroom and before, during and after food prep

Washing all food prep surfaces, dishes and utensils with hot water and soap after use

Thoroughly washing or peeling fresh fruits and veggies before eating them

Avoiding swimming if you have diarrhea, and waiting at least two weeks to swim after it goes away
