Nanomotors have been controlled inside living cells for the first time, report a team of chemists and engineers. The scientists placed tiny rocket-shaped synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically to spin and to battering against the cell membrane.

Why was my first thought reading this was about a government trying to get a vile of these and using it as a poison to literally beat some guy from the inside of his cells to death?

It would be kind of cool to see if they could be built to only slip inside a cancerous cell and beat them to death.

That is pretty cool, but I have to say, these seem very simplistic in comparison to my expectations. They seem like micro brute force so far, but I look forward to the next generation.

Yeh, these nano-motors have been around, but in the cell is pretty impressive. Interesting use in cancer therapy hopefully, well if they can be target specific to cancer cells.

I lulzed when I saw this.

http://www.nature.com...

Its about why THC in marijuana makes you eat more. I mean its cool science but it always makes me wonder why do people do this. I guess I need to understand more neuroscience.

With obesity becoming the worlds biggest health problem I imagine any method of better understanding the neuroscience of hunger is potentially life saving on a massive scale. But yeah lol all the same.

That actually makes a lot of sense. Sometimes it just the dots that need to be connected. Thanks.

Obesity has nothing to do with neuroscience other than crap labeled as food messing with the brain. And most "experts" telling that carbohydrates are the way to go when it comes to diet.

Remove all grain products, emphasis on wheat and corn products. Limit your carb intake to maximally about 50 grams a day, probably even 50 is too much. And for fvcks sake eat meat and animal fat! Eggs and fish too.
And your obesity will roll away over the months.

I highlighted the part I think you should read again. That's neuroscience.

Cell-autonomous correction of ring chromosomes in human induced pluripotent stem cells.

This study is awesome as they show using iPSCs that ring chromosomes self heal. Hence chromosome defects in cells can be cured by reprogramming. Pretty cool stuff this, when we consider that this is the cause behind some aneuploidy genetic diseases/disorders.

Something in science I think is simply amazing is the Alcubierre Drive

http://www.extremetech.com...

I hope they can actually develop it. We must find exotic matter!

I must say this is pretty interesting stuff. I think the biggest problem is what will the consequences be. Well that is if it is even possible in the first place.

I know, the best part about this though is it is a loophole around time dilation! I hope that it can become reality with little to no negative effects.

The next generation came before these, actually. I started seeing articles on nanoparticles that specifically target and deliver drugs into cancerous cells about a year or two ago.
Everything is up for questioning. If it won't defend itself, then how do we know it can?

Experiments on Seismic Metamaterials: Molding Surface Waves

Not sure if the link is open access so I will just post the general gist from Nature. Its pretty cool stuff.

"An array of deep holes in the ground seems to lessen shaking in certain locations during a simulated earthquake.

St"phane Br"l" of soil-engineering company M"nard in Nozay, France, and his colleagues drilled a grid of boreholes 5 metres deep into the soil near Grenoble. A crane then lowered a probe into the ground nearby, where it vibrated to simulate an earthquake. The boreholes were located in places where the seismic waves interfered with one another and cancelled each other out. Thus, the array of holes deflected much of the seismic energy and bounced it back towards the source.

The approach could lead to new ways to protect buildings from shaking during earthquakes, the authors say."

Saw this blurb on Nature today. Have to say its cool and weird all in one.

"Exercise wheels are popular among laboratory mice, but it seems that wild mice " and even frogs and shrews " also use them to go for a jog.

Some have argued that wheel-running is not a natural behaviour and could even be a result of neurosis. Johanna Meijer and Yuri Robbers at Leiden University Medical Centre in the Netherlands set up exercise wheels at two sites where wild mice live, and collected video for more than three years. They found that the median running speed of wild mice was lower than that of their captive counterparts, but wild mice reached higher maximum speeds. The animals were initially attracted to the equipment by food rewards, but continued to use the wheels when food was absent.

The study suggests that wheel-running is a voluntary behaviour, the authors say.

I highly doubt it's first use will be to understand obesity. It will be to make synthetic, nutrient poor, sh*t I mean food more desirable. The funds are probably from McDonald's parent company.

One side effect is there is no causal relationship from the space bubble inside to the bubble outside, so no steering. Plus the bend traps high energy particles so you eradicate what ever you stop near with high burst gamma radiation.

Still worth investigating
