Welcome indoors, solar cells
Posted by Genevieve Klien in categories: internet, particle physics, solar power, sustainability
Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.
As the internet of things expands, it is expected that we will need to have millions of products online, both in public spaces and in homes. Many of these will be the multitude of sensors to detect and measure moisture, particle concentrations, temperature and other parameters. For this reason, the demand for small and cheap sources of renewable energy is increasing rapidly, in order to reduce the need for frequent and expensive battery replacements.
This is where organic solar cells come in. Not only are they flexible, cheap to manufacture and suitable for manufacture as large surfaces in a printing press, they have one further advantage: the light-absorbing layer consists of a mixture of donor and acceptor materials, which gives considerable flexibility in tuning the solar cells such that they are optimised for different spectra – for light of different wavelengths.

This Dried Up Riverbed Shows that Water Once Flowed on the Surface of Mars
Posted by Genevieve Klien in categories: habitats, space
From some viewpoints, Mars is kind of like a skeleton of Earth. We can see that it had volcanoes, oceans, and rivers, but the volcanoes no longer fume and the water is all gone. A new image from the ESA’s Mars Express drives the point home.
The new image is of Nirgal Vallis, one of the longest dried-up river system on Mars, at almost 700 km (435 miles) long. It’s just south of the equator, in a region shaped not only by water flowing on the ancient surface, but by impacts.

Internet loves Astrophysicist’s expression after finding out about his Nobel Prize
Posted by Genevieve Klien in categories: internet, physics, space
The Nobel Prize for physics was announced on October 8 where Mayor jointly shared half of the prize with Didier Quelzo while the other half was awarded to James Peebles. Both Mayor and Didier jointly discovered a planet outside our solar system, an exoplanet, orbiting a solar-type star.

SpaceX gives South Texas homeowners more time to consider buyout offers
Posted by Genevieve Klien in category: space travel
SpaceX is giving Boca Chica Village homeowners more time to consider its buyout offer and is agreeing to reappraise the properties after complaints that the original appraisals were too low.
Last month, the Hawthorne, Calif.-based rocket company sent property owners a letter dated Sept. 12, offering them three times the value of their homes based on appraisals SpaceX had commissioned. The deadline for accepting the offer was two weeks from the date of the letter and the offer was non-negotiable.
SpaceX said it wants to buy the properties due to a greater-than-anticipated disruption to residents and property owners as development of the company’s Mars rocket, Starship, gains steam.

The Mitochondria are the power stations of every cell in our body, turning the food we eat into energy
Posted by Tanvir Ahmed in categories: biotech/medical, food, life extension
Unfortunately, as we age they begin to breakdown due to damage.
MitoSENS project aims to reverse that damage with the goal of preventing age-related ill health. In their first study, they managed to show that allotopic expression of two mtDNA genes from the nucleus could bring back several functions in a patient cell line.
MitoSENS team is currently running a crowdfunding campaign on Lifespan.io to collect money for the next crucial step of this project. Scientists want to investigate if functional backup copies of mitochondrial DNA genes in the nucleus can replace their mutated counterparts in live animals, and if this could rescue mitochondrial function.

Liz Parrish talk at RAADfest 2019 (05oct19)
Posted by John Davies in categories: biotech/medical, life extension
This year I had the privilege to record in full Liz Parrish talk delivered at RAADfest 2019 (Revolution Against Aging and Death Festival 2019), which took place in Las Vegas, NV from 3 to 6 of October.
During her talk, Liz tells us about recent developments in the field of gene therapy and what her company BioViva is doing to benefit society by harnessing the power of it.

Porsche teams up with Boeing to build flying cars for rich people
Posted by Omuterema Akhahenda in category: transportation
Porsche and Boeing are teaming up to build luxury, electric-powered vertical takeoff and landing (VTOL) aircraft for rich people to fly above traffic-choked cities. They are the latest companies to announce intentions to explore the risky and potentially dangerous urban air mobility market.
Porsche and Boeing have signed a nonexclusive memorandum of understanding, which means they will look for ways to work together, but they aren’t locked into a binding agreement. As part of the partnership, the companies say they will “create an international team to address various aspects of urban air mobility, including analysis of the market potential for premium vehicles and possible use cases.”
The word “premium” would seem to indicate that this won’t be a “flying car” for the masses, which is fair considering we’re talking about Porsche here. Many companies interested in creating a network of electric flying taxis have stretched credulity by insisting that people at all income levels will be able to afford to purchase tickets. But given the costs associated with creating an infrastructure to support electric vertical takeoff and landing (eVTOL) aircraft, including landing pads and charging stations, it seems clear that it will be marketed toward the very wealthy — at least to start.

Will We Survive Mars? — Glad You Asked S1 (E1)
Posted by Derick Lee in categories: biotech/medical, space
NASA says the first humans will set foot on Mars in the mid-2030’s. It will be the most dangerous mission any human has ever taken. Glad You Asked host Cleo Abram wants to know: What comes after that? Not how do we get there, but how will we survive once we do?
Note: There are several Fahrenheit measurements in this piece.
The metric conversions are:
At 7:53: 212 degrees Fahrenheit = 100 degrees Celsius
At 8:04: 98.6 degrees Fahrenheit = 37 degrees Celsius
At 8:45: −81 degrees Fahrenheit = −62.8 degrees Celsius
