The Likely Cause of Addiction Has Been Discovered and It Is Not What You Think

The Likely Cause of Addiction Has Been Discovered and It Is Not What You Think | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
This isn't only relevant to the addicts I love. It is relevant to all of us, because it forces us to think differently about ourselves. Human beings are bonding animals. We need to connect and love. The wisest sentence of the 20th century was E.M. Forster's, "Only connect." But we have created an environment and a culture that cut us off from connection. The rise of addiction is a symptom of a deeper sickness in the way we live, constantly directing our gaze toward the next shiny object we should buy, rather than the human beings all around us.

The writer George Monbiot has called this the "age of loneliness." We have created human societies where it is easier for people to become cut off from all human connection. The Internet offers only a parody of connection. Bruce Alexander, the creator of Rat Park, told me that for too long, we have talked exclusively about individual recovery from addiction. We need now to talk about social recovery; how we all recover, together, from the sickness of isolation.

First-of-its-kind tube laser created for on-chip optical communications

First-of-its-kind tube laser created for on-chip optical communications | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it

Nanophotonics, which takes advantage of the much faster speed of light compared with electrons, could potentially lead to future optical computers that transmit large amounts of data at very high speeds. Working toward this goal, researchers in a new study have developed a tiny laser 100 micrometers long and 5 micrometers in diameter—right at the limit of what the unaided human eye can see. As the first rolled-up semiconductor tube laser that is electrically powered, it can fit on an optical chip and serve as the light source for future optical communications technology.


A team of engineers, M. H. T. Dastjerdi, et al., at McGill University in Montreal have reported their development of the tiny laser in a recent issue of Applied Physics Letters. Future optical chips will require many vital components, such as modulators (which convert electrical signals into optical ones), photodetectors (which do the reverse), and waveguides (which control the path of light). Another essential requirement is, of course, the light itself, which may come from a micro- or nano-scale laser that can be integrated with the other components onto a silicon (Si) platform.


Although many different types of micro-sized lasers have been studied over the past several years, one promising candidate is a laser made from rolled-up semiconductor tubes. These lasers are fabricated by straining 2D nanomembranes on a substrate, and then selectively releasing parts of the nanomembranes so that they roll up into tiny tubes that act as optical cavities. The rolled-up tube lasers have an advantage over most other types of small lasers in that their optical emission characteristics can be precisely tailored using standard photolithography processes. They can also be easily transferred onto a Si platform, allowing for seamless integration with other chip components.


"In contrast to electrically injected devices, optically pumped devices require additional light sources (lasers, LEDs) to operate that take additional space on the chip and add a significant level of complexity," Zetian Mi, Associate Professor at McGill University, told Phys.org. "Therefore, optically pumped light sources are not practical for integrated chip-level optical communication systems."


As the researchers explain, fabricating electrically powered rolled-up tube lasers is difficult because the very thin nanomembranes make the process of injecting charge carriers into the laser very inefficient. To overcome this problem, the researchers designed the laser to lie horizontally on top of two supporting pieces connected to the electrodes in a U-shaped mesa design. In this formation, charge carriers are injected into the laser cavity from the sides. By circumventing the thin membrane walls, this lateral carrier injection scheme emits light from the center of the tube laser, significantly increasing injection efficiency.

Latest OS X 10.10.2 beta kills Google-disclosed vulnerabilities dead

Latest OS X 10.10.2 beta kills Google-disclosed vulnerabilities dead | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
Google's Project Zero research program has disclosed and released proof-of-concept code for a series of 0day — previously unknown — vulnerabilities found in Apple's OS X operating system for the Mac. These exploits are all fixed in OS X Yosemite 10.10.2, now in beta. Here's a report on the vulnerabilities from Ars Technica:

In the past two days, Project Zero has disclosed OS X vulnerabilities here, here, and here. At first glance, none of them appear to be highly critical, since all three appear to require the attacker to already have some access to a targeted machine. What's more, the first vulnerability, the one involving the "networkd 'effective_audit_token' XPC," may already have been mitigated in OS X Yosemite, but if so the Google advisory doesn't make this explicit and Apple doesn't publicly discuss security matters with reporters.

This chart of rising ocean temperatures is terrifying

This chart of rising ocean temperatures is terrifying | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
This year’s biggest climate change news was that 2014 was hottest year on record. Turns out, there’s bigger news: It was also the hottest year in the oceans, which are warming so fast they’re literally breaking the NOAA’s charts.

Don’t think you mind a little jacuzzification in your ocean? You’re wrong. Warmer oceans matter because “global warming” doesn’t just mean above average air temperatures over the course of a year — it actually refers to an increase in the total amount of heat energy contained in the Earth’s systems. While air temperatures can fluctuate on any given year, they are usually matched by an increase or decrease of the amount of heat stored in the oceans (which, by the way, absorb around 90 percent of total global warming heat). To know whether the system as a whole is getting warmer or not, scientists need to take into account the temperatures of the atmosphere, land, AND oceans.

Elon Musk vs. Richard Branson: The Race For Cheap Satellite Internet

Elon Musk vs. Richard Branson: The Race For Cheap Satellite Internet | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
Over four billion people don’t have Internet access. That’s more than half the population of Earth. How do we fix that? The answer lies over our head. Two billionaires are in a battle to create a network of tiny satellites that can bring cheap Internet access to the masses.
In November 2014, Elon Musk confirmed rumours that he was building a fleet of satellites to provide affordable Internet. He officially announced the project this January, but was beat to the punch by Richard Branson of Virgin, who is launching the world’s largest satellite constellation in collaboration with Qualcomm and OneWeb.
Neither of these billionaires is new to the space race. Musk is the founder of SpaceX, the electric sportscar manufacturer Tesla and other technological ventures. Branson is an inspirational entrepreneur with many investments, one of which is the world’s first commercial spaceline, Virgin Galactic.
So what’s special about space Internet, to attract the likes of Musk and Branson?

Nanopillar semiconductors shape up for better, cheaper solar cells

Nanopillar semiconductors shape up for better, cheaper solar cells | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
Solar cells could become more efficient and less expensive, thanks to the development of tapered nanopillar semiconductors that are narrow at the top and wide at the bottom. Created by chemist Ali Javey and his group from California’s Lawrence Berkeley National Laboratory, the two-micron-high nanopillars’ unique shape allows them to collect as much or more light than conventional semiconductors, while using much less material.

“To enhance the broad-band optical absorption efficiency of our nanopillars we used a novel dual-diameter structure that features a small (60 nanometers) diameter tip with minimal reflectance to allow more light in, and a large (130 nanometers) diameter base for maximal absorption to enable more light to be converted into electricity,” said Javey. “This dual-diameter structure absorbed 99 percent of incident visible light, compared to the 85 percent absorption by our earlier nanopillars, which had the same diameter along their entire length.”

University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a “quantum speed limit” on processes ranging from quantum computing and tunneling to optical switching.

The energy-time uncertainty relationship is the flip side of the Heisenberg uncertainty principle, which sets limits on how precisely you can measure position and speed, and has been the bedrock of quantum mechanics for nearly 100 years. It has become so well-known that it has infected literature and popular culture with the idea that the act of observing affects what we observe.

First Human Protein Atlas and major protein analysis published

First Human Protein Atlas and major protein analysis published | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it

The Human Protein Atlas, a major multinational research project supported by the Knut and Alice Wallenberg Foundation, recently launched (November 6, 2014) an open source tissue-based interactive map of the human protein. Based on 13 million annotated images, the database maps the distribution of proteins in all major tissues and organs in the human body, showing both proteins restricted to certain tissues, such as the brain, heart, or liver, and those present in all. As an open access resource, it is expected to help drive the development of new diagnostics and drugs, but also to provide basic insights in normal human biology.


In the Science article, "Tissue-based Atlas of the Human Proteome", the approximately 20,000 protein coding genes in humans have been analysed and classified using a combination of genomics, transcriptomics, proteomics, and antibody-based profiling, says the article's lead author, Mathias Uhlén, Professor of Microbiology at Stockholm's KTH Royal Institute of Technology and the director of the Human Protein Atlas program. The analysis shows that almost half of the protein-coding genes are expressed in a ubiquitous manner and thus found in all analysed tissues.


Approximately 15% of the genes show an enriched expression in one or several tissues or organs, including well-known tissue-specific proteins, such as insulin and troponin. The testes, or testicles, have the most tissue-enriched proteins followed by the brain and the liver. The analysis suggests that approximately 3,000 proteins are secreted from the cells and an additional 5,500 proteins are located to the membrane systems of the cells.


"This is important information for the pharmaceutical industry. We show that 70% of the current targets for approved pharmaceutical drugs are either secreted or membrane-bound proteins," Uhlén says. "Interestingly, 30% of these protein targets are found in all analysed tissues and organs. This could help explain some side effects of drugs and thus might have consequences for future drug development." The analysis also contains a study of the metabolic reactions occurring in different parts of the human body. The most specialised organ is the liver with a large number of chemical reactions not found in other parts of the human body.

BMW demonstrated such technical prowess this month with a specially equipped BMW i3 at the International CES event. At a multilevel garage of the SLS Las Vegas hotel, a BMW engineer spoke into a Samsung Gear S smartwatch.

“BMW, go park yourself,” and off the electric vehicle scurried to an empty parking spot, turning and backing itself perfectly into the open space. To retrieve the car, a tap on the watch and another command, “BMW, pick me up,” returned the car to the engineer.
