7000 pound Rivian pickup versus guard rail at 60 mph

^^^That was amazing. I don't understand the engine sound. Sounded like one of the GA planes over my house (200 a day). Aren't Rivians electric? The sound quit the instant the truck hit.

The way it took out the K rail was insane. I guess that was more of the point than how well the truck survived.

Lots of little tricks here:
https://yewtu.be/watch?v=7RBCXCV-T-4&listen=false
Superglue, a lot, can be used with baking soda-graphite-sand to repair plastic. Drop your moto? You can fix it with all the pieces.
A screen and soldering iron to embed can do the same.
Refill WD-40 or spraypaint cans with a compressor and tire stem.
All kinds.

The researchers used a 3D printing approach called laser powder bed fusion to achieve this metamaterial design. This approach uses a high-powered laser beam to melt layers of metal powder into place.

The double lattice design ensured that it halved the stress at the weak points in the design, and any cracks in the design were also deflected along the structure, thereby improving its toughness.

The team tested a titanium lattice cube made using this approach. It was 50 percent stronger than the cast magnesium alloy WE54, the strongest alloy known to humanity and used widely in aerospace applications. The team is still working on perfecting the metamaterial and hopes that it can improve its temperature-bearing limit to 1,112 Fahrenheit (600 degrees Celsius) and potentially add more applications to its list.

Just heard on the radio that UF is doing trials on a kit that uses paper test strips and saliva like a glucose monitor to detect cancer markers

I believe in some cases that these sorts of crashes are performed by the vehicle being dragged by a cable, so the sound that you heard was likely the cable running over pulleys with gear and motor noise.

Once it’s gone, heavy equipment will dismantle the structure. All that will remain of the 11-kilometer-long reservoir that filled the valley for 60 years will be steep-sided slopes coated in gray mud, split once again by a free-flowing river.

Within months, however, that sediment will be covered with a fine, green carpet of seedlings and colorful splashes of flowers, many planted by Chenoweth’s team. Eventually, if all goes as hoped, patches of Gary oak, desert gooseberry, and mock orange will take hold and a lush ribbon of cottonwood, willow, and ash trees will line the banks of the river. Beneath their boughs, salmon that last migrated through this valley more than a century ago will return.

I don't know, maybe it's just me, but every time I hear of a dam removal it makes me feel like civilization and progress are reversing. Makes me fear a return to the cave...

Watching again it sounds like a plane overhead. I did hear a clinking chain like noise as you pointed out.

I love seeing new tool innovations. Some are actually affordable and practical enough to buy.

edit: Zeke I especially liked the overhead belt/backpack crane wire tool balancer oddly enough.
Combined with a spring hip/knee/foot enhancements a man could pick up a bale of wet hay and walk around all day. Hah.
What a weird idea. The Army has looked into it but the idea goes back to 1980's Japanese battle space suit cartoons and before.
Always been fascinated with natural robotic prosthetics and exoskeleton enhancements from early on.

The chainsaw bark remover on an extension was pretty cool as well. Gets one thinking.

john70t, there are some great tools in those vids. Some are not that new and some are silly, but overall very good. I especially liked the wine cork gizmo.

ASCO 2024: New ultra-sensitive blood test predicts recurrence of breast cancer, months or even years before relapse

Molecular residual disease was detected in all 11 patients who relapsed. The median lead time to clinical relapse in this group of patients was 15 months, an increase of over three months, compared with current tests in all types of breast cancer. The longest lead time to clinical relapse was 41 months.

None of the 60 women in whom ctDNA remained undetected, relapsed throughout the follow-up period. Three patients had ctDNA detected in follow-up but had not relapsed by the end of the study – the researchers didn’t have samples to analyse beyond the study follow-up period. Median survival for ctDNA detected patients was 62 months and not reached for the patients in whom ctDNA was undetected.

Earth’s core has slowed so much it’s moving backward, scientists confirm. Here’s what it could mean
https://www.yahoo.com/news/scientists-ve-confirmed-slowdown-earth-100054337.html

The sloshing of metal-rich fluid in the outer core generates electrical currents that power Earth’s magnetic field, which protects our planet from deadly solar radiation.

They say that Mars was once like the Earth, then it's core stopped, cooled and then the atmosphere was lost.


https://scied.ucar.edu/learning-zone/sun-space-weather/earth-magnetosphere#:~:text=Without%20the%20magnetospher e%2C%20Earth%27s%20layered,Earth%20wouldn%27t%20be %20possible.

The magnetosphere deflects much of the solar particles and energy that stream towards Earth at all times. Without the magnetosphere, Earth's layered atmosphere would deteriorate due to the constant bombardment of solar wind. And without our uniquely layered atmosphere, which protects us from harmful ultraviolet (UV) radiation and traps heat, life on Earth wouldn't be possible.

It was fun while it lasted.
