Marvin Schur, a 93-year-old man from Bay City, Michigan has died after the electric company limited his electric use due to his failure to pay over US$1,000 in past-due payments.

Bay City Electric Light & Power installed a power-limiting device on his home on January 13. The device would limit the amount of power the resident uses and would essentially shut it off if that limit is reached, or if the resident fails to pay the outstanding bill within 10 days of installation. In order for the electricity to be turned back on, the limiter must be reset by pushing a button.

Bay City power says that a warning, indicating that the power was to be turned off and a limiter installed, had been placed on Schur’s front door. Despite that, the company says that they are now “looking at our website and possibly doing an automated phone message. We obviously need to get the word out.”

The autopsy performed on Schur’s body concluded that he had died “a slow, painful death” caused by hypothermia. Dr. Kanu Virani, who performed the autopsy, explained: “Hypothermia shuts the whole system down, slowly. It’s not easy to die from hypothermia without first realizing your fingers and toes feel like they’re burning.”

It was less than 32 degrees Fahrenheit (0 Centigrade) in Schur’s home when neighbors found Schur dead on January 17. Virani commented that it was his first time performing an autopsy on a body in which “the person froze to death indoors.”

“His furnace was not running – the insides of his windows were full of ice the morning we found him,” said George A. Pauwels Jr., who was with his wife when they found Schur’s body.

In Michigan it is illegal for a utility company to disconnect power to any home between November 1 and March 31 when a resident is over the age of 65. Limiters are also not supposed to be used during that time frame. However, municipally-owned electric utilities like the one in Bay City, are not regulated by the state. The Michigan state attorney general’s office has launched an investigation into the incident.

Residents around Schur’s home say he was hard of hearing, and the city states that the device’s function and operation were never explained to him. When word of the story got around, people from all over the United States began to call the city in anger.

“I’ve taken calls from Canada, Massachusetts, Texas, New York, Alabama – and that’s just the ones I can think of off the top of my head,” said Melody Roth of the city’s administrative office, who also added that people from all over are “calling all city departments, not just our office.”

Schur has no known children, and his wife had died several years prior to the incident.

In findings published Wednesday in the scientific journal Cell, a team of scientists from the Chinese Academy of Sciences in Shanghai, China have announced the first-ever cloning of a primate from post-embryonic cells, namely two macaque monkeys. They used somatic cell nuclear transfer, the same method that was used to create Dolly the sheep in 1996.

In somatic cell nuclear transfer, scientists remove the nucleus, which is the organelle that contains the chromosomes, from an unfertilized ovum, or egg cell, and implant the nucleus from a somatic cell, or non-reproductive cell, into that ovum. The ovum is then stimulated and develops in the normal way, growing into a whole organism that has the same nuclear DNA as the donor organism, though it will have all of the ovum’s mitochondria and other cellular machinery. Clones like these have been described as identical twins to their donors, but younger.

The scientists implanted 21 ova into surrogate mother monkeys, resulting in six pregnancies, two of which produced living animals. The young clones were named “Zhong Zhong” and “Hua Hua,” both derived from Zh?nghuá, the Chinese-language word for the Chinese people. They are both cynomolgus monkeys, or crab-eating macaques (Macaca fascicularis). The scientists also attempted to clone macaques using nuclei from adult donors. They implanted 42 surrogates, resulting in 22 pregnancies, but there were still only two infant macaques, and they died soon after birth. The Scotland-based team that created Dolly the sheep in 1996 required 277 attempts and produced only one lamb.

Generally, the older the donor organism, the more difficult it is to get the DNA from the harvested nucleus to reactivate the genes that allow the clone organism to grow. Previous efforts to clone rhesus monkeys (Macaca mulatta) using embryonic donor cells have been successful, but the current attempt used significantly older donors: fetal fibroblast cells, which are key cells in connective tissue, and adult monkey cumulus cells.

“We’re excited — extremely excited,” said study co-author Muming Poo. “This is really, I think, a breakthrough for biomedicine.” He went on to say that the cloned monkeys could be used as test subjects for the study of neurological diseases such as Parkinson’s and Huntington’s. Primates are already a popular model organism for neurological studies. In the United States, for example, non-human primates are used in less than 0.3% of all animal experiments, most of them involving neuroscience, and macaques in particular are a well-established animal model of atherosclerosis, which causes heart disease.

“I think it’s a very exciting landmark. It’s a major advance,” agreed reproductive biologist Dieter Egli of Columbia University. “It should be possible to make models of human disease in those monkeys and study those and then attempt to cure it.”

About 90% of the laboratory animals used in the United States are rodents. Although the first cloned mouse was born in 1998, cloned mice are not currently common in laboratory settings. This may be because producing inbred mouse lines is still relatively effective.

Although the announcement raised enthusiasm from researchers, it also drew caution from bioethicists. “Cloning one individual in the image of another really sort of demeans the significance of us as individuals,” says Harvard Medical School’s Dr. George Daley, speaking specifically of cloning humans. “There’s a certain sort of gut sense that it violates sort of natural norms.” While Muming Poo concedes it is now theoretically possible to clone a human, he says his lab has no plans to do so.

Although somatic cell nuclear transfer was used successfully in amphibians as early as 1952, getting it to work in mammals took much longer. Dolly, the first cloned mammal, was born in 1996. Teams have been trying to clone monkeys for decades, but primate DNA is notoriously difficult to work with. “The trick is we choose the right chemicals to turn on these genes we transfer into the egg,” Mu-ming Poo told the press. “So that’s what we did different. I think that’s the key.” One of the agents used to treat the ova was messenger RNA from the human Kdm4d gene.

United States President Donald Trump announced on Tuesday, that Rex Tillerson will no longer serve as the Secretary of State. Trump will nominate Mike Pompeo, the current CIA director as Tillerson’s successor, and Deputy Director Gina Haspel will be nominated to replace Pompeo. The Secretary of State is the U.S. equivalent of a foreign minister in most other countries.

Trump first made the announcement in an early morning tweet at 5:43 AM ET (UTC?04:00). The State Department said in a statement, Tillerson “did not speak to the President and is unaware of the reason” for his dismissal from office.

The President spoke to the press on the South Lawn of the White House later on Tuesday, saying “I’ve worked with Mike Pompeo now for quite some time. Tremendous energy, tremendous intellect. We’re always on the same wavelength. The relationship has always been very good and that’s what I need as Secretary of State.”

Trump wished Tillerson well, adding that “Rex and I have been talking about this for a long time. We — we got along actually quite well, but we disagreed on things,” continued the President. “When you look at the Iran deal, I think it’s terrible. I guess he thought it was OK. I wanted to either break it or do something, and he felt a little bit differently.”

According to NBC News and Reuters, there have been months of disagreements between Trump and Tillerson leading up to the dismissal.

At 3:45 p.m. Tuesday, Eastern Time (2045 UTC), the SpaceX Falcon Heavy rocket launched from Kennedy Space Center in Florida, United States. Its cargo: a US$100,000 Tesla sportscar, the personal property of SpaceX CEO Elon Musk, which he hopes will soon be in its own orbit around the Sun. This is the most powerful rocket since the Saturn V of Project Apollo was retired in 1970. The rocket is meant to follow a course called a Hohmann transfer orbit.

“It’ll be a really huge downer if it blows up,” Musk told the press the day before the launch, but went on to say, “If something goes wrong, hopefully it goes wrong far into the mission so we at least learn as much as possible along the way. I would consider it a win if it just clears the pad and doesn’t blow the pad to smithereens. That’s four million pounds of TNT equivalent so there’s probably not going to be much left if that thing lets loose on the pad.” The car was equipped with a fully space-suited dummy, cameras to monitor its trip into space, a copy of Douglas Adams’ Hitchhiker’s Guide to the Galaxy, and a radio blasting Space Oddity by David Bowie.

The Falcon Heavy has a total of 27 engines and stands 230 feet (70.1 m) tall. According to SpaceX, the Falcon Heavy uses three boosters, the same kind as the company’s smaller cargo rockets. After the rocket exited the Earth’s atmosphere, two of these boosters detached from the main body of the rocket and, in a first for space technology, were successfully guided back down to the landing pad about ten minutes after launch. The third was to have landed on a drone ship, but missed by around 100 yards (about 90 meters) and hit the ocean “at around 200 miles per hour,” according to Musk. The reusability of the boosters makes an enormous difference in the cost of the launch.

Even the relatively heavy-hauling U.S. Space Shuttle program, which was closed in 2013, did not rely on rockets as powerful as those used in Project Apollo, the program in which NASA, the U.S. Government space agency, sent manned missions to the Moon in the 1960’s and 70’s. Most recent space projects have focused on smaller, lighter machinery, such as Scaled Composites’ SpaceShipOne in 2004, which reached space after being carried part of the way by a carrier jet instead of launching from the ground. As of last week, the most powerful rocket in use was the Delta IV, operated by the United Space Alliance. It costs about US$435 million per launch, while SpaceX says the Falcon Heavy will cost US$90 million per launch.

NASA is also working on a heavy-duty rocket, the Space Launch System, but there have been delays.

The Independent Monitoring Commission has reported that the Provisional Irish Republican Army has undergone major changes within their military structure and shows that the IRA Army Council wants to put its military campaign behind it. The Commission consists of John Alderdice, a former Alliance Party leader; Joe Brosnan, former Secretary General of the Department of Justice, Republic of Ireland; John Grieve, former Deputy Assistant Commissioner of the Metropolitan Police and former head of the Metropolitan Police Anti-Terror Branch; and Dick Kerr, former Deputy Director of Central Intelligence Agency.

The report states the IRA no longer has the capacity to mount a military campaign anymore or return to one. The units that have been shut down were responsible for weapons-making, arms smuggling and training. The IRA decommissioned their arms last year.

The report also mentions that the IRA has also put its criminality beyond use and is “clamping down” on criminals within the organization, said Lord Alderdice, as he presented the report. He also added, “That doesn’t mean that criminal activity by all members has stopped but the leadership has made public statements and internal directions, investigated incidents of breach of the policy, even expelled some members and has emphasised the importance of ensuring that business affairs are conducted in a legitimate way.”

Finally, the report added that there is not enough evidence or intelligence to identify who killed Denis Donaldson, a British spy who infiltrated the IRA and Sinn Fein, before revealing his status as a spy.

However, the report added that splinter groups like the Real IRA (RIRA) and Continuity IRA (CIRA) are still threats and are still continuing their activity. The Real IRA was the group behind the deadly 1998 Omagh bombing. The Irish National Liberation Army (INLA) “was not capable of undertaking a sustained campaign [against the British State], nor does it aspire to” according to the report.

It is also noted the creation of two new organizations, Oglaigh na hEireann (Irish Gaelic for “Volunteers of Ireland” and is used by the Irish Defence Forces and the various IRAs.) and the Republican Defence Army. However, the groups are small dissident factions according to the report.

The report also added that the two loyalist paramilitaries, the Ulster Defence Association (UDA) and the Ulster Volunteer Force (UVF) are also beginning to move from violence but at slower pace and not at a grassroots level like the IRA. Another loyalist paramilitary, the Loyalist Volunteer Force

The report was received warmly by Irish Toaiseach Bertie Ahern and British Prime Minister Tony Blair. Ahern, said “These positive and clear-cut findings are of the utmost importance and significance. It is time to make decisions and for Northern Ireland to look to the future.”

“The IRA has done what we asked it to do, and while issues like policing remain to be solved, the door is now open to a final settlement, which is why the talks next week in Scotland are going to be so important.” said Tony Blair in a live statement.

In a surprising reaction, the notoriously hardline leader of the Democratic Unionist Party, Ian Paisley, also welcomed the report. He believes that his party’s pressure is working and if Sinn Fein signs up to policing there could be a deal. Paisley said, “If the police question is settled absolutely on a democratic basis and principle we would have come a long way along the road.”

Sinn Fein leader Gerry Adams said “The DUP don’t have anything other than very limited options. They will or will not participate in power-sharing arrangements. If they don’t participate they are condemning people here, but particularly their own constituents, to second class public services, run by second class fly-in, fly-out British ministers. All the DUP can do is to delay, is to attempt to slow down, but they can’t stop the process of changing.”
