Cyberbullying in any form can be traumatizing for kids

Computers and Math from Science Daily Feed - Thu, 05/15/2025 - 10:19am
New research shows that cyberbullying should be classified as an adverse childhood experience due to its strong link to trauma. Even subtle forms -- like exclusion from group chats -- can trigger PTSD-level distress. Nearly 90% of teens experienced some form of cyberbullying, accounting for 32% of the variation in trauma symptoms. Indirect harassment was most common, with more than half reporting hurtful comments, rumors or deliberate exclusion. What mattered most was the overall amount of cyberbullying: the more often a student was targeted, the more trauma symptoms they showed.

Stretched in a cross pattern: Our neighboring galaxy is pulled in two axes

Space and time from Science Daily Feed - Thu, 05/15/2025 - 10:17am
Researchers have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud, are moving in opposing directions along two distinct axes. They found that stars closer to Earth move towards the northeast, while more distant stars move southwest. This newly discovered movement pattern exists alongside a northwest-southeast opposing movement that the scientists previously observed in massive stars.

Readers’ wildlife photos

Why Evolution is True Feed - Thu, 05/15/2025 - 6:15am

Today we have some lovely insect photos by regular Mark Sturtevant. Mark’s ID’s and captions are indented, and you can enlarge his photos by clicking on them.

Here are more pictures of insects taken two summers ago from area parks near where I live in eastern Michigan.

First up is a slightly embarrassing accomplishment, which is a decent picture of one of our Sulphur butterflies. Sulphurs are an exceedingly common group with several local species, but for some reason they are extremely wary around me. Anyway, this one was unwary, and I think it is the Orange Sulphur (Colias eurytheme):

Next up is our largest butterfly, the Eastern Giant Swallowtail (Heraclides cresphontes). They are often challenging since they tend to keep their “engines running” (meaning their wings are almost always in motion) when rapidly foraging from flower to flower, but this one paused very briefly:

One of my favorite insects is shown next. This is Anotia uhleri, or what I call the “Flat Derbid”, although this Derbid planthopper has no common name. They can be found in forests sitting on the undersides of leaves. The orange thingies sticking out of the head are stumpy antennae:

Here is a Leaf-footed Bug nymph (Acanthocephala terminalis):

I was finding quite a few of these Lacewing egg clusters along a forest trail. Lacewings lay eggs on the ends of long stalks for protection. Having the eggs tied together in a bundle suggests that these are one of our larger Green Lacewing species, Leucochrysa insularis. This species tends to stay in forests, sitting under leaves by day, and like the Derbid above they lay their wings flat.

An occasional visitor to the porchlight at home are Mosquitos of Unusual Size, and one is shown in the next picture. I was eventually able to identify this giant mosquito as the GallnipperPsorophora ciliata. This one is a female. Although she will require a blood meal to reproduce, and they are described as being rather aggressive in pursuit of humans, a relatively good thing about them is that the larvae are predatory on other mosquito larvae. I have pictures coming up later that compares one of these beasts to a regular mosquito, but for now the attached picture can give some idea:

The next three pictures show a surprise, but the story starts out unremarkably. The beetles foraging on flower pollen are Brown Blister BeetlesZonitis vittigera. Blister Beetles are a large family, and are so-named because they are chemically protected by exuding an irritating fluid if annoyed. It is relevant to point out that they have interesting biology in that they grow up as parasites on other insects, usually on bees. The mobile first instar larvae are called triungulin larvae, and they start their journey by clambering up onto flowers and wait for a bee to visit. Once the flower is visited by their intended target, they hitch a ride to the nest where they move in and eat the bee provisions and even bee larvae:

I almost did not bother processing the 2nd picture because it had motion-blur, though the composition was nice. But do you see the tiny things on the thorax of the beetle? The 3rd picture provides a blow-up. Those little things are Blister Beetle triungulin larvae! Possibly not this species, though. So, what is going on? I have sent these pictures on to a Blister Beetle Facebook group and to iNaturalist to ask for opinions. There is no answer yet, but possibly the larvae attach to any insect visitor. Although non-bee visitors would be temporary dead-ends, one can imagine that this would at least disperse them to other flowers:

Finally, here are pictures of our most common Sand Wasp, which is the Four-banded Stink Bug Wasp (Bicyrtes quadrifasciatus). Females of these highly energetic wasps will provision a burrow with paralyzed stink bugs, and these are used to raise the next generation of wasps. In the first picture you can see the spray of sand being flung out as she excavates her burrow:

Water Ice Found in Another Star System

Universe Today Feed - Thu, 05/15/2025 - 2:22am

Just as ice dominates the outer Solar System, blanketing the moons of giant planets and coating objects in the Kuiper Belt and Oort Cloud—astronomers using the James Webb Space Telescope have made a chilly discovery in a distant planetary system. The alien system HD 181327, 155 light-years away harbours significant deposits of both ordinary and crystalline water ice. They detected the ice in regions that are farther away from the star, with the outer area containing as much as 20% water ice.

Venus Might Have Tectonic Activity After All

Universe Today Feed - Thu, 05/15/2025 - 1:26am

One of the big differences between Venus and Earth is the lack of plate tectonics. While Earth's continents float on tectonic plates—constantly reshaping our world—Venus was previously thought to remain locked in a largely static crust with only occasional volcanic hotspots. But everything we thought we knew might be wrong! Researchers examining 30-year-old NASA Magellan spacecraft images have spotted what appears to be the smoking gun of tectonic activity on our hellish sister planet, potentially rewriting planetary science as we know it.

Understanding carbon traps

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:16pm
As industries seek innovative solutions for carbon capture, scientists have turned to advanced materials that efficiently trap and store carbon dioxide (CO ) from industrial emissions. A recent study sheds light on the gas adsorption physics of so-called Calgary Framework 20 (CALF-20), a zinc-based metal-organic framework (MOF). While applying a combination of advanced techniques, the scientists reveal the material's unique adaptability under varying conditions.

New study offers insights into designing safe, effective nasal vaccines

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:12pm
Most vaccines -- and boosters -- are injected directly into muscle tissue, usually in the upper arm, to kickstart the body's immune system in the fight against disease. But for respiratory diseases like COVID-19, it can be important to have protection right where the virus enters: the respiratory tract. In a new study, researchers found that nasal vaccine boosters can trigger strong immune defenses in the respiratory tract, even without the help of immune-boosting ingredients known as adjuvants. The findings, researchers suggest, may offer critical insights into developing safer, more effective nasal vaccines in the future.

Drinking water, select foods linked to PFAS in California adults

Matter and energy from Science Daily Feed - Wed, 05/14/2025 - 3:09pm
A new study examined associations between diet, drinking water, and 'legacy' PFAS -- chemicals that were phased out of production in the US in the 2000s -- with blood samples from California residents. PFAS exposure was associated with consumption of seafood, eggs, and brown rice, but fewer other foods than suggested by earlier studies. PFAS levels were elevated among people who lived in areas where these chemicals were detectable in their drinking water supply, but lower than levels found in highly contaminated communities.
