A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

On Tuesday many internet routers, used to find the pathways to different parts of the web, reached their memory limit of 512,000 entries in the tables they use to store the routes, causing problems for many users.

A router is used to direct a user towards the area of the internet where they will find the content they are looking for, e.g. a web page. The recent problem was caused by the arbitrary memory limit built into the design of many aging routers. A limit was needed to prevent the cost of hardware from becoming prohibitively expensive in the days when physical data storage was still comparatively expensive. This small amount of memory in turn limits the number of directions which can be stored on a single router leading to different parts of the internet. When this limit was reached, it caused outages of services among Internet Service Providers. Many routers, including older ones provided by Cisco Systems Inc., are limited to storing a total of 512,000 routes or paths.

This limit was reached on Tuesday, reported to have been triggered by Verizon publishing another 15,000 paths. Those affected included eBay, LastPass, and clients of the web hosting company Liquid Web, who lost much of their services until Verizon withdrew some of these new paths. Problems nevertheless continued throughout the day, even after the withdrawal.

A longer term fix is possible, but it would require manually replacing old routers with newer, more capable ones. It is hard to tell what issues would temporarily cascade though the internet by taking down routers from part of the internet for maintenance. Many experts have warned that problems could continue until these difficult fixes have been implemented, although the recent switch to a newer form of IP Addresses, IPv6, will temporarily help the issue. Wired News reported that Andre Toonk, a network engineer, had stated that the number of network outages on the internet, typically around 1,500, yesterday peaked at 2,587, enough to become clearly noticeable.

The spread of coronavirus in late 2019 and then in 2020 led to a global pandemic, affecting various daily activities. Originating in Wuhan, China, the virus spread globally, and by March, drastic measures were taken by the Indian government. Some branches of the South Western Railway of India had started taking precautions by distributing masks to ticket collectors and guards from as early as March 8. Some colleges were suspended by March 13, their exams postponed as the government introduced lockdown and enforced social distancing.

Announced in the evening, the Indian Prime Minister asked his countrymen to get the essential products and avoid going out as much as possible. Long queues outside the grocery shops, people in masks, some in N-95 masks, and hand sanitisers at the gates of megamarts were a common sight. There were reduced items in the shops, and some stores had a limit of the number of customers allowed in the store at any given time. Food delivery services, and taxi services were on hiatus — workers who depended on the profession for their daily income, while people including software engineers were working from home. Physical classes in schools and colleges were replaced by online lectures to prevent social gatherings.

While many relied on technology for continuing their work and earn their livelihood, Wikinews reached out to sex workers in Mysore in June who, unlike others, can’t maintain social distancing for their work. Two sex workers, Akram Pasha, and Jaya (a pseudonym), who were part of a sex worker’s group called “Ashodaya Samithi” discussed how their lives had been affected by the coronavirus, the lockdown and the restrictions they had faced.

American corporation DivX, Inc. announced on Monday that it will shut its Stage6 website that hosts videos made by users. The shutdown will take effect on February 28, 2008 and is because the firm no longer have the resources to keep it online.

“Why are we shutting the service down? Well, the short answer is that the continued operation of Stage6 is a very expensive enterprise that requires an enormous amount of attention and resources that we are not in a position to continue to provide. There are a lot of other details involved, but at the end of the day it’s really as simple as that,” said Tom, who is also known as ‘Spinner’ in the statement on the website and an employee of DivX, Inc. the San Diego, California-based host of the webservice.

In October 2007, Universal Music Group filed a federal lawsuit against DivX, Inc. for copyright infringement after users posted hundreds of music videos on Stage6.

Chief Executive Kevin Hell said in a statement: “By no longer expending resources on Stage6, we sharpen our focus on creating a global standard for digital video.”

Videos can no longer be uploaded, but will be able to be watched and downloaded until February 28. Stage6 made its debut in 2006. It hosted movie clips, television shows and music videos along with content made by the site’s users in the popular DivX codec.

The Western Australian (WA) Environmental Protection Authority (EPA) has advised against the massive Greater Gorgon liquefied natural gas project off WA’s Pilbara coast. Proponents of the projects say Gorgon is one of Australia’s biggest export ventures, scheduled to provide up to 6,000 jobs and exports of up to $1.2 billion.

EPA chairman Dr Wally Cox said the Gorgon project operators (Chevron, ExxonMobil, and Shell), had made an effort on flora and fauna issues but in its present state, the Gorgon proposal was “unacceptable.” Gorgon LNG general manager Colin Beckett said that Gorgon was a world-class gas field and that the joint venture partners were confident that the decision would be reversed.

Environment Minister Mark McGowan said there was a definite process to be followed. The Minister says he will make a final decision on the Gorgon proposal after considering the EPA report – and any subsequent report from the Appeals Convenor. The EPA recommendations on the Gorgon proposal are subject to a two-week appeals period.

The EPA’s Dr Cox said that joint venture had “not been able to demonstrate that impacts from dredging, the introduction of non-indigenous species and the potential loss of fauna could be reduced to acceptable levels.”

In September 2003 the WA government provided “in-principle agreement” to the Gorgon joint venturers subject to a number of conditions. Dr Cox said that the Environmental Review and Management Programme had further highlighted the terrestrial and marine conservation values of Barrow Island and the adjacent waters.

“Flatback turtles in particular would be put at risk from the proposal with two of the most important nesting beaches located adjacent to the proposed LNG processing plant site and the materials off-loading facility,” Dr Cox said. “There is very little science available on the life-cycle, behaviour and feeding habits of Flatback turtles and as a consequence it is not possible at this time to identify management measures that would ensure ongoing survival of this Pilbara Flatback turtle population.”

Dr Cox also said that the Proponent had not been able to demonstrate that risk could be reduced to satisfactory levels in the areas of: Impacts on the marine ecosystem from dredging; The introduction of non-indigenous species; Potential loss of subterranean and short range endemic invertebrate fauna species. “As a result, the proposal in its present form cannot meet the EPA’s environmental objectives and is considered environmentally unacceptable,” Dr Cox said.
