On Saturday, Discovery Science Place hosted a mini Maker Faire in Tyler, Texas. Multiple vendors and exhibitors were on hand. An art car, featuring what might be the largest collection of singing robotic lobsters anywhere in the world was on display, curiously titled the “Sashimi Tabernacle Choir.” A large modular analog synthesizer was also available for attendees to experiment with, designed by staff at Synthesizers.com.

Some exhibits were quite simple, showing how to modify inexpensive radio-controlled cars using epoxy and LEGO bricks. Two three-dimensional printers were displayed, showing attendees how the new technology operates. Outdoor exhibits included multiple forms of robots and flying drone-style aircraft (see video below). According to a news release, the event is one of 60 planned to occur worldwide this year.

Numerous volunteers were on hand to assist with the event. Colleges and university groups were on hand, including representatives from The University of Texas at Tyler, among others.

24 of 26 Swiss Cantons rejected the proposal for a single health insurance system, in which premiums would be based on income and wealth. The vote on Sunday was the latest in a series of attempts to cut rising costs and ease the financial burden on citizens.

Around 71% of voters rejected the reform. Turnout was at about 46%, slightly above the Swiss average.

As expected, voters in the main German-speaking part of the country turned down the planned reform, which was supported by the centre-left but opposed by the centre-right as well as the business community, parliament and the government.

Opposition in the French and Italian speaking regions was less pronounced. The cantons Jura and Neuchâtel in the French speaking regions voted in favor of the proposed reforms.

Health insurance premiums are higher in southern and western Swiss cantons than in German-speaking areas.

The Swiss Interior Minister Pascal Couchepin said an important part of the Swiss Population appeared to be opposed to “a revolution” in health insurance but he said that he wanted current reforms currently under discussion in the Swiss Parliament to go ahead. He called on all sides, especially health insurers and the cantonal authorities, to make efforts to reduce spending on health insurance and aim for a greater cost efficiency. Currently Switzerland has 87 private insurers providing mandatory basic health care coverage for Swiss residents under a 1996 law. But costs have sky-rocketed. Over 100,000 people are not covered by health insurance due to non payment.

Opponents to the initiative argued that a single insurance system would lead to complacency and create a two-tier system, in which the wealthy would be the only ones available to afford to have additional private insurance coverage.

Supporters of the initiative said a single health insurer would increase the system’s efficiency and allow for annual savings of at least 300 million Swiss Francs (about $245 million) in administrative costs. Currently, the funding system is unbalanced, since many clients on low incomes use state subsidies to pay their premiums, according to the Green Party and the Social Democrats.

The initiative to unite all the insurance companies and introduce premiums based on wealth and income was the most recent in a series of attempts over the past ten years to reduce the public spending on health care. A proposal, similar to this recent proposal, to modify the funding system of the health insurance companies was rejected by 73% of voters in 2003.

Switzerland has the most expensive health system in Europe. Switzerland’s expenditure on health care was 11.6% in 2005, in front of Germany and France but behind the United States.

This week, the Public Broadcasting Service aired a NOVA program titled “Dimming the Earth”, which presented research by leading scientists on the complex systems of our global climate and human activity’s effect on it. One of the largest interactions (or “inputs”) humans have with the atmosphere is the ever-increasing use of fossil fuels. Consumption has risen 2% per year for this decade.

Fossil fuels burnt in factories and automobiles send their waste into our atmosphere in two forms. The first is CO₂ and other greenhouse gases, which have received substantial attention in the last few years because of the way they trap heat in the atmosphere. The second is the tiny particles of sulfur dioxide, soot and ash, which scientists call aerosols (basically smog). Research into understanding the negative health effects of air pollution has resulted in the development of catalytic converters for cars as well as devices to remove particulate solids from industrial waste before it reaches the air.

More recently, atmospheric scientists have come upon the phenomenon of the reduction of direct sunlight reaching Earth’s surface— observing a nearly a 5% decline between 1960 and 1990, with evidence of a recovery since then. This has been dubbed the “global dimming” effect, and is probably due to the way these aerosols act upon clouds. It is important to realise that this does not represent a net loss of this much sunshine to the climate system – if so, large temperature declines would have been observed. Instead, the sunshine is absorbed elsewhere in the system, with a much smaller net loss.

Clouds form when moisture gathers around airborne particles, such as pollen or dust. Clouds formed by the aerosol particles emitted by fossil fuel consumption are made of many more tiny droplets than “natural” clouds. These smog-created clouds have two notable effects: they shield sunlight from reaching Earth’s surface and, due to water’s reflective nature, the millions of tiny droplets suspended in them reflect light back into space, allowing even less light to reach Earth.

Many scientists now believe that global dimming caused by these pollutants has mitigated the temperature rises brought about by global warming. Over the last thirty years, Earth’s temperature has increased by about 0.5 oC.

In the absence of global dimming, however, the Earth might be 0.3 oC warmer than it currently is, suggesting that a “tug-of-war” exists between greenhouse gases and particulates released by burning fossil fuels. Efforts to mitigate the human health dangers of smog have allowed more heat into our atmosphere and brought about a sharper increase in global warming.

Dr. James E. Hansen, professor at Columbia University and the head of the Goddard Institute for Space Studies [1], believes that if we continue on our current pattern, this warming could be as much as five degrees in the next thirty years and ten to fourteen degrees over the course of the century. Such a temperature rise would devastate life on Earth, likely bringing on a cascade of self-reinforcing warming effects. Earth’s forests drying and burning, a steady thawing of the Greenland and arctic ice sheets, and, most dangerous of all, a release of the methane hydrates that are now frozen at the bottom of the oceans, could remake the planet into something inhospitable to human life. Dr. Hansen warns that, according to his research, man has just 10 years to reduce greenhouse gases before global warming and other responses to human activity by Earth’s climate reach a “tipping point”, becoming unstoppable.

Ivy Bean, thought to have been the oldest person using the popular social networking site Twitter, has died at age 104.

By the end of her life, Bean had 53,535 followers (a term used on Twitter to indicate you are watching a person’s posts) on the site and was something of an internet phenomenon. In 2008, she became known as the oldest person on Facebook, a title held previously by a 97-year-old French man. Bean frequently updated her Twitter page with videos and descriptions of activities in her daily life that included her winning of the Gold Medal in Frisbee in the Over-75 Olympics in Bradford, Northern England as well as recipes and meeting former British Prime Minister Gordon Brown.

At the beginning of July, Bean was admitted to hospital suffering from jaundice. On July 23rd, Bean returned to the care home where she was a resident, but was no longer able to operate her Twitter account. Manager of the care home Pat Wright took over the account and began posting on Bean’s behalf.

It was posted on July 26th that Bean was in a poor condition and yesterday, Wright posted “Ivy passed away peacefully at 12.08 this morning”.

Many of Bean’s followers posted messages of condolence, making Bean the second-most discussed topic on the Twitter yesterday. Among her followers were Peter Andre and Chris Evans.

Ivy Bean was born November 8, 1905, seven years before the telephone network was established.

A seven story concrete apartment building in the Naniwanaka Naniwa Ward of Osaka, Japan was set ablaze, killing at least 15 people. The fire started early in the morning on October 1st in the Video DVD Cat sex shop on the first floor.

At least eight people were rescued from the building, four of whom were seriously injured in the fire. Most of the injuries and deaths were caused by smoke inhalation and carbon monoxide poisoning. According to authorities, all of the fatalities were in private viewing rooms in a video shop that was located on the first floor of the building.

The sex shop had 32 cubicles for watching videos, all of which were equipped with a bed, television, and video deck. Due to the beds, and a shower, shops like this are often used as cheap hotels. A customer, who fled to safety when the fire started, said to the media that the inside of shop was dark, and that he had difficulty seeing where he was going as he escaped.

Witnesses said that they first noticed a burning smell at 2:30am local time, and that the fire was reported to Osaka Fire Department around 3am. 40 fire trucks and 120 firefighters took part in the efforts to bring the blaze under control. The fire was extinguished at around 4:30am, after burning for about one and a half hours. The cause of the fire is not yet known.
