More than half your body is not human

Posted by in categories: biotech/medical, health

More than half of your body is not human, say scientists.

Human cells make up only 43% of the body’s total cell count. The rest are microscopic colonists.

Understanding this hidden half of ourselves — our microbiome — is rapidly transforming understanding of diseases from allergy to Parkinson’s.

This is the COOLEST! Everything that’s Orbiting the Earth Right Now

Posted by in categories: computing, engineering, satellites

Okay, if you’ve got some spare time, check out this amazing website called Stuff in Space. It’s a simulation of every satellite (alive or dead), space station, and large piece of space junk orbiting the Earth right now.

You can zoom in and out, rotate the Earth and its satellites around. Pick any one object and discover more information about it. Or just leave it running and watch all the objects buzz around in real time. Humans have been busy launching a lot of stuff, and it’s only going to increase.

The simulation was made by James Yoder, an incoming Electrical and Computer Engineering freshman at the University of Texas at Austin, and it’s based on data supplied by Space Track, which is a service of the Joint Space Operations Center. They have a bunch of handy data feeds and APIs that you can use track orbital objects, but I’ve never seen anything as creative as this.

This imaging sensor is powered by sunlight

Posted by in categories: solar power, sustainability

A simultaneous imaging and energy harvesting sensor is in the news. Samuel Moore at IEEE Spectrum informed readers that a team of four from University of Michigan published their paper describing what they achieved. They built a prototype sensor, and what it does—-think of a future camera that just about watches you non-stop—is described in the journal, IEEE Electron Device Letters.

The article is titled “Simultaneous Imaging and Energy Harvesting in CMOS Image Sensor Pixels.” The four authors are from University of Michigan: Sung-Yun Park, Kyuseok Lee, Hyunsoo Song and Euisik Yoon.

Their technology “puts the equivalent of a solar cell under each pixel,” said IEEE Spectrum.

Harnessing ‘Rashba spin-Seebeck effect’ phenomenon will enable commercial devices to turn waste heat into electricity

Posted by in categories: computing, solar power, sustainability, transportation

Mechanical engineers at the University of California, Riverside, have reported success in using inexpensive materials to produce thermoelectric devices that transform low-level waste heat into electricity.

Their advance could enable a wide variety of commercial applications. For example, integrating thermoelectric generating devices into computer chips could enable the they produce to provide a power source. Waste heat from automobile engines could run a car’s electronics and provide cooling. Photovoltaic solar cells could be made more efficient by harnessing the heat from sunlight striking them to generate more electricity.

Also, using the same basic technology, economical thermoelectric refrigerators could be produced that would be more energy efficient and with fewer moving parts than refrigerators that use compressors and coolant. Current thermoelectric refrigerators are expensive and relatively inefficient. In essence, they operate in reverse of , with an electric current applied to generate a temperature gradient that could be used in cooling.

Elon Musk: We Must Leave Earth For One Critical Reason

Posted by in categories: asteroid/comet impacts, Elon Musk, existential risks, particle physics

In its early life, the Earth would have been peppered nearly continuously by asteroids smashing into our young planet. These fiery collisions made our world what it is today. It may seem like things have changed since then, given the vast assortment of life and wide blue oceans—and things have indeed changed. At least in some respects. However, Earth still receives thousands of tons of matter from space, but this is in the form of microscopic dust particles (as opposed to recurrent, energetic collisions).

Fortunately, in modern times, a large asteroid colliding with the surface of the Earth happens only very rarely. Nevertheless, it does happen from time to time.

As most are probably already aware, it is widely believed that an asteroid initiated the dinosaurs’ extinction some 65 million years ago. And more recently, the Russian Chelyabinsk meteor hit our planet in February of 2013. It entered at a shallow angle at 60 times the speed of sound. Upon contact with our atmosphere, it exploded in an air burst. The size of this body of rock (before it burned up and shattered) is estimated to be around 20 meters (across) and it weighed some 13,000 metric tons.
