Swiss mining company Glencore announced yesterday the closure of its coal mine in Tahmoor, New South Wales, Australia. The mine is to be closed by early 2019, pointing to the downturn of coal prices in global markets.

Glencore stated, “The decision has been made as a result of continued low prices in global coal markets, which has meant the economic return from reserves still available at Tahmoor are not sufficient to warrant the investment required to mine them”.

The closure will result in a loss of 350 jobs according to the company, who said they are consulting with the employees.

The mine is not the only operation impacted by the fall of global coal and commodity prices. The Australian arm of mining magnate Peabody Energy has reported losses of almost A$3 billion in 2015. According to latest financial reports for Peabody subsidiary Peabody Australia Holdco lodged via Australian Securities and Investments Commission, the company earned a net loss of A$2.7 billion — after a loss of A$1.2 billion in 2014. Accountants at Peabody Australia have warned the mine might not be able to continue operating, with the market persistently weak since December.

Despite low coal and commodity prices, both the major political parties have been supportive of coal mines. While appearing on the ABC’s Q&A program on Monday night, Coalition MP Steve Ciobo confirmed party support of coal mines. In response to an audience member question, concerning what policies the panellists had planned to combat job and economic loses in Queensland after the mining boom, Ciobo stated the Coalition government supports Adani’s new Carmichael mine in the Galilee Basin — as an example of “transitioning” the state’s economy.

Labor MP Terri Butler said although she doesn’t personally support Adani’s Carmichael project, the state Labor government “didn’t have much discretion” surrounding its approval. Meanwhile, Greens party leader Richard Di Natale criticised responses from the panellists claiming the “great tragedy” is both major parties support of coal mines such as Carmichael.

“If you care about tourism you don’t open up a whopping great big coal mine and fuel catastrophic global warming”, said Di Natale.

Di Natale accused both major parties of being deceitful in “slashing” both the target of and agency funding for renewable energy, leaving no plan to realize the investment potential of the renewable sector.

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.

Recently, Finnish open-source video game developer Perttu Ahola discussed Minetest, his “longest ever project”, with Wikinews.

Started in October 2010, Minetest was an attempt by Ahola to create a sandbox game similar to Minecraft. Minecraft is a multi-platform commercial game, which was in alpha version when Ahola challenged himself to create something similar to it from scratch, he told Wikinews.

Minetest is an open-source game, which is free for anyone to download and play. It is written in the C++ programming language, and the source code is available on code-hosting site GitHub. According to Ahola, Minetest attempts to run on older hardware, with limited graphics, but to be accessible to more people: those who have outdated technology, and making it available for no cost. Minecraft, on the other hand, is a paid game, currently costing USD 26.95 for its computer version. Minecraft is currently owned by Microsoft, and performs poorly on older hardware.

A correspondent from French Wikinews contacted Perttu Ahola via Internet Relay Chat a few weeks ago, discussing Minecraft. This interview is built on top of the previous interview, as we take a deeper dive into knowing more about this free game which is about to turn ten years old in a few months.
