Cern has published its ideas for a £20bn successor to the Large Hadron Collider, given the working name of Future Circular Collider (FCC).

The Geneva based particle physics research centre is proposing an accelerator that is almost four times longer and ten times more powerful.

The aim is to have the FCC hunting for new sub-atomic particles by 2050.
...
Prof Jon Butterworth of University College, London is among those drawing up the strategy. He told BBC News that, although he was keeping an open mind, he was particularly attracted to Cern's proposal.

It entails gradually building up to a 100km ring that is almost ten times more powerful than the LHC.


Wow! Just watch out for the black holes and worm holes it will create. ;)

PM 2.5 problems in Asia -
http://www.koreaherald.com/view.php?ud=20190123000626
South Korea plans to conduct this year’s first artificial rain experiment over the Yellow Sea on Friday, as part of efforts to tackle fine dust pollution amid growing concerns over public health.

The Korea Meteorological Administration said Wednesday the one-hour experiment will be conducted in the sea between the Korean Peninsula and China on Friday morning, with a plane, boat and other devices mobilized to measure meteorological conditions.

The KMA will carry out a cloud seeding experiment and observe changes in particles in the clouds. The Ministry of Environment will then analyze whether the artificially produced rain helps get rid of fine and ultrafine dust in the air.
...
However, the impact of artificial rain on dust reduction or broader weather patterns is not yet known. Some pointed out that the humidity caused by cloud seeding could enlarge dust particles, therefore worsening the pollution. There are also environmental questions over the use of silver iodide.


Meanwhile in Thailand - https://www.bangkokpost.com/news/general/1615894/drone-zone-smog-battle-takes-to-skies
Authorities are toying with the idea of using drones to combat haze caused by PM2.5 which has shrouded Bangkok and its surrounding provinces for over two weeks. A test run is being conducted this week.

He said 12 drones were provided by private and state organisations for the test mission.

Meanwhile, Prime Minister Prayut Chan-o-cha has declared the test runs a success.

He said China had also used drones to combat haze, including spraying chemicals into the air.

The South Korean government’s first artificial rain experiment this year over the Yellow Sea failed to induce rain, the Korea Meteorological Administration said Monday, with 14 more experiments planned throughout the year.

The KMA observed an increase in the size of precipitation particles in the clouds, but there was no rain or snow, it said, announcing the interim result of the experiment carried out Friday.

The KMA and Ministry of Environment conducted the cloud seeding experiment over the sea about 11 kilometers southwest of Gunsan, North Jeolla Province, to increase precipitation and analyze whether the rainfall, if any, could help reduce fine dust in the air.

Interesting how they want to fight air pollution in the lower atmosphere by bringing in particles in the upper atmosphere (still troposphere of course). For diffusive droplet growth to start, usually a nucleus, like Aerosoles, are required. As soon as the droplet size passes a specific radius of about 0.5 micrometers, the droplets will grow regardless of decreasing supersaturation in the cloud. However, this also means if you fail to produce rain in the desired area it becomes more likely that rain falls in other areas, thus decreasing the relative humidity in the region and making it more unlikely for the required super saturation to occur and for precipitation to happen naturally (looking at relatively small space and time frames).

https://www.theguardian.com/world/2019/jan/30/toxic-smog-forces-bangkok-to-close-hundreds-of-schools
Toxic smog forced Bangkok authorities to issue an unprecedented order to shut nearly 450 schools on Wednesday as authorities struggled to manage a pollution crisis that has stirred widespread concern.

The Thai capital has been shrouded in murky haze for weeks, forcing residents to don masks and sparking social media criticism of the uneven response by the government.

Reasons given for the lingering pall include exhaust from traffic, unfettered construction, the burning of crop stubble, and pollution from factories getting trapped in the city.
...
Fleets of drones are set to be deployed to disperse sugary liquid solution to help clear the air of microscopic particles. It is not clear how effective that will be given the scale of the smog cloaking the city.

Aswin also said city hall may soon issue a warning against exercising in parks.

Air Visual, an independent online air quality index (AQI) monitor, on Thursday pegged Bangkok at the “unhealthy” level of 171, up from 156 mid-month.

Update - https://www.bangkokpost.com/news/general/1620634/haze-shutters-city-schools
Bangkok governor Aswin Kwanmuang ordered the closure of 437 schools run by the Bangkok Metropolitan Administration (BMA) until tomorrow. The order came into effect Wednesday at noon. "The decision was made to safeguard small children from health risks," Pol Gen Aswin posted on his Facebook page.
The governor said 50 drones will be deployed to spray water in critically haze-hit areas today and tomorrow, he said, adding City Hall is prepared to send mobile medical units for those affected by the by the haze over the weekend.

This appears to be the best place to put this article. It appears that for the first time in about 100 years a black panther has been spotted in Africa (and apparently near where the fictional country of Wakanda is located). Here's the article from the NY Times:

RIP Opportunity.
https://apnews.com/868e731d260f4919b28218dcf345071f?utm_medium=AP&utm_source=Twitter&utm_campaign=SocialFlow
NASA’s Opportunity, the Mars rover that was built to operate for just three months but kept going and going, rolling across the rocky red soil, was pronounced dead Wednesday, 15 years after it landed on the planet.

The six-wheeled vehicle that helped gather critical evidence that ancient Mars might have been hospitable to life was remarkably spry up until eight months ago, when it was finally doomed by a ferocious dust storm.

Flight controllers tried numerous times to make contact, and sent one final series of recovery commands Tuesday night, along with one last wake-up song, Billie Holiday’s “I’ll Be Seeing You,” in a somber exercise that brought tears to team members’ eyes. There was no response from space, only silence.

Thomas Zurbuchen, head of NASA’s science missions, broke the news at what amounted to a funeral at the space agency’s Jet Propulsion Laboratory in Pasadena, California, announcing the demise of “our beloved Opportunity.”

“This is a hard day,” project manager John Callas said at an auditorium packed with hundreds of current and former members of the team that oversaw Opportunity and its long-deceased identical twin, Spirit. “Even though it’s a machine and we’re saying goodbye, it’s still very hard and very poignant, but we had to do that. We came to that point.”

The government issued fine dust emergency measures for all parts of the country except Jeju Island on Friday, as fine dust blanketed Korea for three consecutive days.

The fine dust levels nationwide are expected to reach “bad” or “very bad” levels except for some parts in Gangwon Province and Jeju Island throughout the day.
...
The city will also close down 434 parking lots at state-run organizations, while government employees need to leave their cars at home if their license plate numbers end with an odd number.

While the emergency measures are in effect, power plants that burn fossil fuels must reduce their output to 80 percent of normal operations and plants that produce a large amount of pollution must take measures to reduce emissions.

Dust particles are expected to remain throughout the weekend.

So much for the cloud seeding. :sad:

It was 150 years ago today,
Sgt Pepper taught the band to play ... no wait a momemnt.

Happy Birthday Periodic Table! - one of Sheldon's favourite tables -
http://tass.com/science/1047675
On March 6, 1869, exactly 150 years ago, Russian chemist Dmitry Mendeleev (1834-1907) presented his periodic table of chemical elements - a graphic description of what was destined to go down in history as the Periodic Law.


So let's all sing along now ... https://www.youtube.com/watch?v=DYW50F42ss8

(deep intake of breath) "There's ... " :D

New Einstein manuscripts revealed

Hebrew U unveils 110 new manuscript pages which shed light on the famed scientist - and the man behind the science.

Even 140 years after Albert Einstein’s birth, his scientific discoveries still impact our lives--lasers, nuclear power, fiber optics, driverless cars, GPS and space travel all trace back to Einstein’s theories. Today, the Hebrew University of Jerusalem (HU) unveiled 110 new manuscript pages, most of which have not been displayed before, and which shed light on the scientist and the man behind the science....

S. Korea to push for artificial rain experiment with China

Environment Minister Cho Myung-rae said Thursday the government plans to step up its cooperation with China to combat worsening pollution by pushing to jointly enforce dust-reducing measures and conduct an artificial rain experiment.

The ministry also plans to launch a pilot project to install large air purifying facilities outdoors in major cities, and tighten restrictions on driving on heavily polluted days.

The ministry said it would push for an artificial rainfall experiment over the sea between the Korean Peninsula and China this year, and exchange rain-making technologies with the neighboring country.

“To reduce fine dust that enters Korea from abroad, it is better to conduct an artificial rain experiment over the Yellow Sea, rather than in inland areas, given the weather conditions,” Cho said at a press briefing. “We believe artificial rain will be effective in reducing levels of fine particles in the air.”

Korea’s first experiment this year with artificial rain, in which chemicals are released into clouds to induce rain, failed to cause precipitation and the experiment will be repeated in March, the ministry said.

A South Korean government laboratory said Friday it will conduct an aerial observation of flows of pollutants over the Yellow Sea to trace the origins of fine dust concentrations over the Korean Peninsula.

The National Institute of Environmental Research, affiliated with the Ministry of Environment, said it will mobilize a 19-seat airplane for a month to intensively observe fine dust particles over the waters between South Korea and China.

The state-run laboratory has previously used a smaller plane for a limited observation of aerial pollutants. It plans to utilize the results of the monthlong observation in future negotiations with China over responsibility for fine dust particles over the peninsula.

Over the past week, most of South Korea, including Seoul, was hit by heavy concentrations of ultrafine particles that were about six times higher than the maximum density recommended by the World Health Organization.

The daily average of particles smaller than 2.5 micrometers in diameter surged close to 150 micrograms per cubic meter in Seoul early this week, the highest levels since record-keeping began in 2015.

President Moon Jae-in ordered his government Wednesday to work with China to fight fine dust pollution. Moon instructed the government to discuss dust-reducing measures with China and look into the possibility of jointly creating artificial rain over the sea between the two countries. South Korea's state-run agencies have said pollutants coming from China are responsible for about 50 to 70 percent of the air pollution over the peninsula.

But China's foreign ministry has denied responsibility for fine dust over the Korean Peninsula, asking Seoul to produce scientific evidence.

Wishing not to start a debate in the cycling sections, I'll post this here. Sir Jim seems to be on a par with SDB with regards to spin, PR & "science".
http://www.cyclingnews.com/news/team-ineos-presented-in-yorkshire-by-froome-and-brailsford/
The most regulated country by a country mile is the US, and they have drilled a million wells or more in America. In the UK we are sat on some potentially extraordinary reserves. Gas is a clean fuel and it creates jobs and investment. Why wouldn't you look at exploiting that in the UK? If I look at the anti-fracking groups, the majority of them are ignorant about fracking. I wouldn't want to get involved in it if it was dangerous. All you do is pump water down, it just loosens the rock a bit. Cheap energy encourages investment in manufacturing. It's outrageous that the government listen to a noisy miniscule minority instead of looking at the science."
