Phys.Org Mobile: Water's reaction with metal oxides opens doors for researchers

Phys.Org Mobile: Water's reaction with metal oxides opens doors for researchers | Science, Technology, and Current Futurism | Scoop.it
excerpt: " In a paper published recently in the journal Nature Communications, Manos Mavrikakis, professor of chemical and biological engineering at the University of Wisconsin-Madison, and his collaborators report fundamental discoveries about how water reacts with metal oxides. The paper opens doors for greater understanding and control of chemical reactions in fields ranging from catalysis to geochemistry and atmospheric chemistry."

Notetaking vs notemaking

Notetaking vs notemaking | Science, Technology, and Current Futurism | Scoop.it

From my review of the notetaking literature (a focus of my dissertation), I found two schools of thought. One was note taking as a record of events. This would correspond to the minutes of a meeting or a transcript of a video. With this concept, teachers would give students a copy of important facts as a handout or file (or make the students copy them from the board or screen). Every student would have the same information in a standard style. [I've interviewed students who listed copying notes as their least favorite class activity.]

 

The other thought is notetaking as a form of information processing (notemaking might be a better term). As students read text, listen to a lecture, participate in a discussion, or watch a video, they connect what they’re seeing or hearing to what they already know, ask questions, reflect on their understanding, and summarize. This could be in a variety of formats depending on the information: Cornell notes, sketches, lists, annotating text, graphic organizers. Much of the literature on science notebooks reflects this concept of note taking.*

Startup Demonstrates Ultra-efficient Stacked Solar Cells | MIT Technology Review

Startup Demonstrates Ultra-efficient Stacked Solar Cells | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it
A novel manufacturing method could make it practical to stack solar cells and convert more of the energy in sunlight into electricity.
Sharrock's insight:

excerpt: "Semprius has come up with three key innovations: a cheap, fast way to stack cells, a proprietary way to electrically connect cells, and a new kind of glue for holding the cells together. In its designs, Semprius uses tiny individual solar cells, each just a millimeter across. That reduces costs for cooling and also helps improve efficiency."

Astrocytes, The Brain's Lesser Known Cells, Get Some Cognitive Respect

"What I thought quite unique was the idea that astrocytes, traditionally considered only guardians and supporters of neurons and other cells, are also involved in the processing of information and in other cognitive behavior," says Verma, a professor in the Laboratory of Genetics and American Cancer Society Professor.

Sharrock's insight:

excerpt: "It's not that astrocytes are quick—they're still slower than neurons. But the new evidence suggests that astrocytes are actively supplying the right environment for gamma waves to occur, which in turn makes the brain more likely to learn and change the strength of its neuronal connections."

Pierre Tran's curator insight, July 10, 1:17 AM

Les transhumanistes sont bien obligés de reconnaître les dangers d'un "totalitarisme cybernétique" que brandit Jaron Lanier.

luiy's curator insight, July 10, 5:30 AM

Here are the most important beliefs of cybernetic totalism:

 

1) That cybernetic patterns of information provide the ultimate and best way to understand reality.


2) That people are no more than cybernetic patterns.


3) That subjective experience either doesn’t exist, or is unimportant because it is some sort of ambient or peripheral effect.


4) That what Darwin described in biology, or something like it, is in fact also the singular, superior description of all creativity and culture.


5) That qualitative as well as quantitative aspects of information systems will be accelerated by Moore’s Law.

 

And finally, the most dramatic:

6) That biology and physics will merge with computer science (becoming biotechnology and nanotechnology), resulting in life and the physical universe becoming mercurial; achieving the supposed nature of computer software. Furthermore, all of this will happen very soon! Since computers are improving so quickly, they will overwhelm all the other cybernetic processes, like people, and will fundamentally change the nature of what’s going on in the familiar neighborhood of Earth at some moment when a new “criticality”is achieved- maybe in about the year 2020. To be a human after that moment will be either impossible or something very different than we now can know.

Google Earth Saves Kenya’s Maasai Mara Elephants With Drones

Google Earth Saves Kenya’s Maasai Mara Elephants With Drones | Science, Technology, and Current Futurism | Scoop.it
Standing in his flatbed truck, Marc Goss touches “take off” on his iPad 3 and a $300 AR Drone whirs into the air as his latest weapon to fight elephant poachers around Kenya’s Maasai Mara National Reserve.
Sharrock's insight:

“Drones are basically the future of conservation; a drone can do what 50 rangers can do,” said James Hardy, a fourth-generation Kenyan and manager of the Mara North Conservancy. “It’s going to reach a point where drones are on the forefront of poaching. At night time we could use it to pick up heat signatures of poachers, maybe a dead elephant if we’re quick enough.”

Collaborative learning for robots | KurzweilAI | Science, Technology, and Current Futurism | Scoop.it

Researchers from MIT’s Laboratory for Information and Decision Systems have developed an algorithm in which distributed agents — such as robots exploring a building — collect data and analyze it independently. Pairs of agents, such as robots passing each other in the hall, then exchange analyses.

In experiments involving several different data sets, the researchers’ distributed algorithm actually outperformed a standard algorithm that works on data aggregated at a single location, as described in an arXiv paper.

Lab-Grown Cheese Made by 'Milking' Genetically Modified Yeast Cells

Lab-Grown Cheese Made by 'Milking' Genetically Modified Yeast Cells | Science, Technology, and Current Futurism | Scoop.it

The team first studied animal genomes to isolate the gene sequences responsible for producing milk protein or casein.  After optimizing the genes to work within yeast, they synthesized the gene from scratch in a genetic compiler, base pair by base pair. There’s no need to touch a cow in the making of the cheese.

These synthetic milk genes are inserted into yeast cells which begin manufacturing caseins. After the cells have been left to do their thing for awhile, the scientists separate yeast from caseins, add sugar (not lactose—making the cheese edible for the lactose intolerant), water, and vegetable oil.

Sharrock's insight:

excerpt: "Cheese is only the latest attempt by scientists to make animal products in the lab."
