A highly dynamic Bluetongue (or catarrhal fever) infection of sheep herds is underway in Germany. From August 2006 till September 9, 2007, 1,833 farms had reported the presence of the infection. From Sept 9. till September 14, 2007, the number of farms reporting infections has grown to 5,686. The number of deaths is estimated around 15,000 sheep.

Bluetongue infection is of viral origin and is harmless to humans. It is an insect-borne viral disease of ruminants, mainly sheep and less frequently of cattle, goats, buffalo, deer, dromedary camels and antelope. There are no reports of human transmission.

The origin of the infection is not clear but it is one of the diseases which is still feared to invade Northern Europe as a consequence of global warming. No official sources are as yet available as the affected sheep farmers have tried to get the news on the media but to no avail.

The disease has also been found in Belgium, France, the Netherlands and Luxembourg. The United Kingdom Department for Environment Food and Rural Affairs says the virus could spread from Northern Europe to the UK, but is unlikely.

In Edinburgh, capital of Scotland, part of an underground water piping system has exploded, forcing local residents to be evacuated. The pipe broke around 03:30 BST (0230 UTC) today, within Allan Park Road, causing flooding in the Slateford area of the city.

A spokesperson for Scottish sewerage and water corporation Scottish Water explained: “Early this morning reports were received of flooding in Allan Park Road and Scottish Water operatives attended the scene. A large diameter water main had burst. The water was shut off and re-routed via other pipes to keep supplies flowing to households in the area. Repairs are under way and the customers affected by the flooding are being offered assistance.”

Stating that repairs to resolve this problem had commenced and would take a few hours to conclude, Lothian and Borders Police have advised that the floods may disrupt the supplies of water and other utilities, as well as transportation on roads and railways in the west of Edinburgh. Hospitals and rest homes in the region have been notified of the incident and bottled water is now anticipated to be supplied at these buildings.

According to local residents, Slateford Road (A70), a major throughway, was closed for several hours this morning. Telephony and broadband in the area is disrupted, with local residents and businesses having to rely on cellphones. Further work, such as digging up the road and using temporary traffic lights, will be required to restore these services in the area.

As of 13:15 BST (1215 UTC), Scottish Water has excavated around the burst main, but has not yet begun work on replacing the damaged section of pipe.

In the United Kingdom, the National Union of Rail, Maritime and Transport Workers (RMT) began a work stoppage at 19:00 BST (18:00 GMT) today after last-minute talks over pay, jobs and disciplinary issues broke down. The stoppage is expected to last 48 hours and could leave millions of travelers without transportation.

Sky News says that there are fears that the strike may affect fan transportation for the England national football team‘s 2010 FIFA World Cup qualifier match against Andorra at Wembley Stadium tomorrow. Football Association (FA) chief executive Ian Watmore announced that the game would continue as planned at 20:15 BST (19:15 GMT) and encouraged spectators to arrive at the stadium early. The stadium gates will now open at 17:45 BST (16:45 GMT).

No extra transport is being put on and overground trains will not stop at Wembley, and car parking and park-and-ride facilities are unavailable at the ground. Fears of lack of transportation raised the possibility that the game would be forced to play behind closed doors without the team’s supporters.

Watmore said that refunds will be available for supporters that do not attend the game. Last week, the FA decided to halt ticket sales at 70,000 in anticipation of a possible strike. Wembley Stadium can accommodate 90,000 fans for football matches.

In years past, the RMT has been known to clash with the London Underground and its privatised contractors Metronet and Tubelines.

On June 5, London Underground offered staff a four-year pay deal or a two-year deal which they called an “above inflation pay rise”. However, the RMT is seeking a 5% pay raise and a commitment to no compulsory redundancies.

The English national football team currently leads their group in the World Cup qualifying with 18 points and a 6–0–0 record. Andorra currently has no points and has lost all six of their matches. Although Andorra has been eliminated from competing in the 2010 World Cup, England is still competing for better placement.

Findings published Monday by a team composed mostly of University of Washington Center for Forensic Science researchers in Nature Human Behaviour report using a form of DNA analysis techniques originally designed for human teeth to track ivory poached from African elephants.

The scientists, in collaboration with the United States Department of Homeland Security, identified the criminal networks that killed the endangered animals and smuggled their valuable tusks across national borders.

The scientists took DNA samples from 4,320 tusks taken from both African bush (Loxodonta africana) and African forest (Loxodonta cyclotis) elephants that were confiscated from 49 separate ivory smuggling events in twelve countries from 2002 to 2019. The scientists found that teeth from the closely related elephants, or even two tusks from the same individual, often surfaced in different shipments that transited through the same ports. The data also showed when criminal networks shifted their operations from between port cities. They inferred poachers were making kills, then separating the tusks at some point along the smuggling route.

The team had been studying DNA analysis on poached tusks for years: in 2018, they found two tusks from different shipments had come from the same animal, which indicated both shipments were from the same kill and transited by the same criminal network. This is the first report of DNA identification tusks that came from elephants in the same families.

Lead author Dr Samuel Wasser said: “Identifying close relatives indicates that poachers are likely going back to the same populations repeatedly — year after year — and tusks are then acquired and smuggled out of Africa on container ships by the same criminal network.” He added: “This criminal strategy makes it much harder for authorities to track and seize these shipments because of the immense pressure they are under to move large volumes of containers quickly through ports.”

Wasser said similar studies will provide law enforcement groups access to a greater range of evidence with which to prosecute poachers and their criminal partners by providing verifiable links between different caches of captured ivory. The researchers concluded in their paper that law enforcement could use their information to discern the ways in which poachers are collaborating.

Humans have used the ivory from elephant tusks to make art, decorations, and tools since prehistory. Many countries have since outlawed the sale of ivory, but poachers continue to kill tens of thousands of elephants each year.

The paper’s authors were from the University of Washington, the U.S. Department of Homeland Security, the U.S. Fish and Wildlife Service, Kenyan-based organisation SeeJ-Africa, the Kenya Wildlife Service, and Singapore’s National Parks Board.

Researchers at Case Western University in Cleveland, Ohio have announced the creation of transgenic mice with substantially improved athletic endurance, which live and breed longer and are more aggressive than genetically unmodified siblings, and are leaner despite consuming 60% more food. The mice have been dubbed “mighty mice” or “supermice” by the popular press and have been compared to cyclist Lance Armstrong.

The changes were created by adding an extra copy of a single gene, PEPCK-C. This gene is already present in the mouse genome, but the modified gene is designed to be strongly active (transcribed) in skeletal muscle. (The natural copy of the gene, most active in the liver, continues to function normally). The gene mediates a crucial rate controlling step of gluconeogenesis and glyceroneogenesis, and its activity helps to allow energy production by the mitochondrial citric acid cycle. In the transgenics, more energy is available to muscle through the burning of fatty acids, with much less production of lactate (a chemical that leads to sore muscles when one exercises). This is not as major a change to the mouse genome as it might seem to the layperson. The PEPCK-C gene is already present in the mouse and a variety of natural mutations could likely cause similar results. The study appears today in the Journal of Biological Chemistry in a paper with lead author Parvin Hakimi from the laboratory of Richard W. Hanson.

The altered mice can run at 20 meters per minute (0.75 miles per hour or 1.2 kilometers per hour) for up to six kilometers (nearly four miles) without stopping. The average treadmill time for strenuous exercise on a 25-degree incline is 31.9 minutes, well in excess of the 19 minute average of unmodified mice. Females can breed at two and a half years of age, whereas most female mice cannot breed after the first year.

A colony of 500 mice has been bred, starting from six independent germline transformations (“founder” mice). The level of PEPCK-C in muscle is 9 units per gram of muscle as opposed to only 0.08 in normal mice. Levels of triglycerides and the number of mitochondria are also increased.

Hanson said that he did not expect that the results would be applicable to humans due to both practical and ethical considerations in addition to the fact that the genes might not function the same way in humans.

This is not the first time that the press has dubbed a genetically modified mouse a “mighty mouse”. Earlier scientists at John Hopkins University announced that they had made mice with massively increased muscle mass that were larger and stronger than their normal cousins. These alterations increased strength rather than endurance through the genetic modification of myostatin and follistatin, or by injection of a soluble form of ACVR2B to block myostatin activity in normal mice.

In order to put the cannabis drug (marijuana) out of reach of minors, the Canadian federal government announced a bill to legalise cannabis for the age group of eighteen and above, on Thursday. The bill would allow adults to possess cannabis publicly, previously a criminal offence.

Canada’s health minister Jane Philpott tweeted, “Today we tabled new legislation to legalise, strictly regulate, and restrict access to cannabis. Our goal: keep it out of the hands of youth, and profits out of the hands of criminals.” ^{((fr))French language: ?Ajd nous avons déposé un nouveau projet de loi pour légaliser le cannabis, le réglementer de manière stricte et en restreindre l’accès. Notre objectif: garder le cannabis hors de la portée des jeunes, & les profits hors des mains des criminels.} The Canadian government, via their official website, explained cannabis is available illegally, and their measures to stop it did not work. Criminal organisations are making money selling cannabis. Under-aged people can obtain the drug easily; they said, “it is easier for our kids to buy cannabis than cigarettes.”

The bill allows provinces and territories to set the age limit above eighteen. In order to prevent criminal gangs from making a profit, selling the drug needs a license permitting its sale. Adults can purchase the drug online from a licensed producer if a retail shop is not available in the province.

Adults can carry up to 30 g (slightly over an ounce) of cannabis and grow at most four cannabis plants at home, for personal use. The plants should be no taller than a metre, the bill proposed. Selling cannabis to minors would be a specific criminal offence.

The legislation requires parliamentary approval and royal assent. If passed, the bill would be under effect by July 2018, the government said. Health and safety experts and law enforcement were consulted before proposing the legislation. Except for medical purposes, possession of the drug remains illegal until the bill is passed. Regardless of the status of the bill, import and export of the drug would be illegal.

Previously when the government increased the taxes on cigarettes to discourage citizens from smoking, a black market for cigarettes developed.

Along with legalising cannabis, the bill would also permit the police officials to use tools like oral fluid drug screeners to detect if drivers are under the influence of the drug. Zero tolerance against drivers under influence of drugs is proposed. The government would also implement a public awareness campaign on the perils of driving under the influence of drugs.

The government still working on the restrictions. Lawmaker and former police chief Bill Blair said, “We do accept that more important work remains to be done.” If the bill is passed, Canada would be the second country to legalise cannabis completely. Uruguay is the first. Some countries, such as Germany, allow medical use of cannabis, but recreational use is prohibited.
