sparky , in Researchers have successfully transferred a gene to produce tobacco plants that lack pollen and viable seeds, while otherwise growing normally
@sparky@lemmy.federate.cc avatar

For those of you wondering how this is useful, tobacco is often used as a model organism in botany. The utility of this technique is less obvious in tobacco but more obvious in fruits, vegetables, etc. think seedless grapes, etc

planetaryprotection ,

Seedless grapes already exist, but I suppose you could now insert the gene into other plants/varieties to make those seedless as well.

I'm thinking more about how big ag companies could use this to prevent farmers from saving seeds/propagating a copyrighted variety (though I don't know if that's common with any crops where the seed itself isn't the end product) or maybe more charitably, preventing their copyrighted plants from cross pollinating neighboring fields of the same species (e.g. ruining that neighbor's non-gmo status).

Finally, this could be useful if it can be "switched on" i.e. by deliberately polluting an invasive plant's gene pool with this gene and then switching it on to stall the invasive's population growth. But I think most invasives are perennials, so would still need to be removed some other way.

It could be used for improving products, but really it'll be DRM for plants. That's what could make money so that's why money was spent.

autotldr Bot , in Tyrannosaur’s last meal was two baby dinosaurs

It is "solid evidence that tyrannosaurs drastically changed their diet as they grew up," said Dr Darla Zelenitsky, from the University of Calgary.

"We now know that these teenage [tyrannosaurs] hunted small, young dinosaurs," said Dr Zelenitsky, one of the lead scientists in this study, which is published in the journal Science Advances.

But, Dr Zelenitsky, added, "these smaller, immature tyrannosaurs were probably not ready to jump into a group of horned dinosaurs, where the adults weighed thousands of kilograms".

Staff at Alberta's Royal Tyrell Museum of Palaeontology eventually noticed small toe-bones sticking out from the ribcage.

"The rock within the ribcage was removed to expose what was hidden inside," explained Dr Therrien, who is the other lead scientist in this study.

While the adults bit and scraped with their powerful "killer banana" teeth, "this animal was selecting and even dissecting its prey - biting off the legs and swallowing them whole".

Powderhorn , in Researchers develop first-ever functional graphene semiconductor

As soon as we have this commercialized, fusion is just around the corner.

It's always a sad thing to hear but 94 and leaving a mark that puts him up there with the greatest minds of all time. Bravo, sir. Bravo!

He did a lot of good work. I also feel happy knowing that we actually found the particle physically while he was still alive. That has got to be satisfying. Rest easy, Higgs. ❤️

People are fucking dumb sometimes. That's all.

Midnitte , in Safer Sunscreen: Stanford researchers explore novel approach to sustainable sun protection

Great research since current sunscreen can be so damaging to reefs.

We thought maybe we can then use them as a novel form of sunscreen because they are so abundant and completely biodegradable

I wonder if eventually we could sidestep the use of bactiophages and instead manufacture the microscopic structures themselves as sunscreen.

There's a good number of biological processes that are much simpler, cheaper, and require much less materials when the biological process is preserved. A good example of this is water cleaning/breaking down sewage with bacteria which give off methane which is also collected as fuel. Given that the main outcome here is sunscreen that doesn't damage biology and it's generally not that expensive to keep sustain life like this, it might make the most sense to simply leave it at production/farming of bacteriophages.

Looking forward to a photographic journal of learning to build similar walls on LallyLuckFarm.

You know it is going to happen.

Coskii , in Why do people hear their names being called in the woods?

If this isn't an SCP, it definitely should be. That being said I've never experienced this and I spent an awful lot of time wandering in the wildernesses in Monterey.

If you hear your name called while collecting samples in [redacted] Forest, ND, DO NOT respond. Calmly walk back to your vehicle and radio for support. An extraction team will be at your location shortly to remove you from the gaze of [redacted].

Oh no. Did you say ND? 👀

I know I heard my name called occasionally as a kid. Clear as day but directionless, seemingly from very close to me. I figured its just a bug in a developing mind. But could also be that my mom got damn angry if I didnt hear her calling so I was always listening for it, and like the article describe, I picked up noise and the brain filled in the expectation.

Why do I hear my name being called in the woods? Gray catbirds

Boomkop3 , in Why do people hear their names being called in the woods?

I've never experienced this, I've been in the woods plenty of times tho

Paradachshund ,

Same, never had this happen and I've also been in the woods many times.

Alsjemenou ,

I would like to add to this. I spend at least 20 hours a week in forests, and have heard a lot of things. Never my name.

Karyoplasma , in Why do people hear their names being called in the woods?

This reminds me of Black & White, the god simulation game from, idk, the early 2000s. They had a list of common names and if your save profile matched one, a creepy voice would call you from time to time.

this is cool

loops ,

That game was so good.

bradorsomething ,

It need to come back on VR head sets.

onlinepersona , in Why do people hear their names being called in the woods?

This is the equivalent of people seeing Jesus in rice grains, but the aural version.
