Two groups of researchers have independently identified the the protein responsible for malaria transmission to mosquitoes in studies published in journal Nature on Sunday.

The scientists found a direct relationship between the protein AP2-G’s with malaria gametocytes (male and female sexual forms) production, which is necessary for the transmission. Only the sexual forms infect mosquitoes and sexual reproduction occurs within the mosquito digestive tract.

Malaria is caused by Plasmodium parasites. The initially separate teams looked at different plasmodium species. One, an international group led by Manuel Llinás of Penn State University in the US, examined Plasmodium falciparum, which is responsible for the worst form of human malarial infections; the other, led by UK scientists Oliver Billker from the Wellcome Trust Sanger Institute in England and Andy Waters from University of Glasgow in Scotland, looked at Plasmodium berghei, which infects rodents.

The P. falciparum group was kickstarted by research in Spain which found different organisms from the same strain with identical DNA had varying levels of AP2-G, with a strong correlation to their levels of sexual activity. The more AP2-G, the higher the rate of gametocyte formation. Researchers in England, later also drawn into the international team, analyzed the genomes of two mutated strains of P. falciparum which were both unable to form gametocytes. They found that the gene responsible for producing the AP2-G protein was the only common non-functioning gene.

The international team found found the AP2-G protein catalyzes the transmission by activating a relevant gene set in the parasite.

Both teams confirmed the finding by gene therapy — both by adding the gene into a mutated strain and observing its ability to form gametocytes, and the other way round.

The parasites exist in a mosquito, then in a human, and require subsequent transmission for the parasite to spread. The transmission can only happen through gametocytes. The parasite triggers formation of the sexual gametocytes into the human’s circulatory system every two days in small quantities — not wasting energy on the process at the dry time of year when few mosquitoes are available — but little was known about the mechanism.

Dr. Oliver Billker commented on the potential of getting the transmission of malaria under control, unlike the existing focus on addressing the phrase causing the clinical symptoms, “Current drugs treat patients by killing the sexless form of the parasite in their blood — this is the detrimental stage of the malaria lifecycle that causes illness. However, it is now widely accepted that to eliminate malaria from an entire region, it will be equally important to kill the sexual forms that transmit the disease.”

The researchers hope to continue research toward drugs to prevent the transmission of the disease. The science was funded by groups including UK research councils, the Spanish government, the U.S. National Institutes of Health, and the European Commission.

Journalist, counselor, painter, and US 2012 Presidential candidate Joe Schriner of Cleveland, Ohio took some time to discuss his campaign with Wikinews in an interview.

Schriner previously ran for president in 2000, 2004, and 2008, but failed to gain much traction in the races. He announced his candidacy for the 2012 race immediately following the 2008 election. Schriner refers to himself as the “Average Joe” candidate, and advocates a pro-life and pro-environmentalist platform. He has been the subject of numerous newspaper articles, and has published public policy papers exploring solutions to American issues.

Wikinews reporter William Saturn? talks with Schriner and discusses his campaign.

Today, Russian opposition leader Alexei Navalny was airlifted from the city of Omsk in Siberia to Berlin, Germany. Navalny has been suffering from a serious medical condition since Thursday. His associates have alleged Navalny was poisoned.

Alexei Navalny is an outspoken critic of Russian president Vladimir Putin. Navalny was transferred from the hospital in Omsk to Charité in Berlin via air ambulance. Cinema for Peace Foundation, a Berlin-based non-profit, provided for the medical evacuation.

On Thursday, Navalny was flying from Tomsk in Siberia headed for Moscow when he fell ill. The flight was redirected to Omsk, so he could be hospitalized. Associates of Navalny alleged he drank tea laced with poison. Hospital officials in Omsk said no traces of poison was found in his blood or urine. As of Friday, Navalny was in a medically induced coma.

Charité said in a statement, Navalny would be undergoing extensive medical diagnostics. His family would be consulted before any comment on his condition would be released. The hospital also asked for patience.

The rescue of the Chilean miners trapped in the San José Mine in Copiapó, codenamed Operación San Lorenzo (San Lorenzo Operation), began on Tuesday night, at around 20:00 local time (23:00 UTC).

Florencio Ávalos was the first miner to be rescued, at 00:12 local time (03:12 UTC) on Wednesday. He was wearing a shirt signed by all his fellow miners. “The first miner is already with us. We saw it all, him hugging his wife Monica and his son Byron,” said President Piñera shortly after the first rescue. “We still have a long journey.”

“This will be recorded on every single Chilean heart forever,” Piñera added. “I hope the miners’ hope stay with us, just like the [February] earthquake victims’ [hope] and what the earthquake took off. We know that the disasters unite us all.”

All the 33 miners were rescued. The last miner, Luis Urzúa, was rescued at 21:55 Chile time (00:55 UTC). “It is a pleasure to be Chilean, [I’m] proud,” said Luis Urzúa to President Piñera. “In honour of the miners, their families, the rescuers […] let’s sing our national anthem. Viva Chile Mierda!,” said Piñera. Urzúa thanked Mining Minister Golborne and the First Lady Cecilia Morel for “fighting for their lives.” “I’m proud of my fellow miners,” Urzúa added.

Six rescuers, including a miner and a paramedic, descended to the miners’ shelter using the Fénix 3 capsule which was specially constructed for the rescue. They performed check-ups and talk with the miners before taking them back to the surface. The rescuers still don’t leave the mine.

The Fénix 3 capsules are 3.95 metres in height and weigh about 460 kilograms. They have an armour, an oxygen tube and a microphone. The occupants helmets contain an intercom to keep them in contact with the rescue team on the surface.

President of Chile Piñera assisted to the rescue. Bolivian President Evo Morales could not attend Carlos Mamani’s rescue. Mamani is the only Bolivian miner in the group.

A mass for the miners was conducted at 18:00 local time (21:00 UTC). The rescue takes between 15 and 20 minutes for each miner.

On Tuesday, Mayor of Copiapó Maglio Cicardini announced that the municipal schools in the city will have no classes this Wednesday “to transform the rescue of the Atacama’s 33 in a familiar meeting,” Radio Cooperativa reported.

“The miners will be taken to the Copiapó Regional Hospital for medical checkup, where they will have to stay for 48 hours,” Health Minister Mañalich said to Televisión Nacional de Chile.

Celebrations are taking place in several Chilean cities. In Santiago de Chile, people gathered in one of the most important points of the city, Plaza Italia. In Pichilemu, tens of cars are passing over its most important streets. In Copiapó, people gathered in its main square to assist a massive concert.

On August 5, 33 miners were trapped more than 700 meters (2,300 ft) underground, in the San José copper–gold mine, located about 40 kilometers north of Copiapó, Chile.

The youngest trapped miner is 19 years old, and the oldest is 63. There were several rescue attempts before reaching the miners’ shelter on August 22. The National Emergencies Office of Chile (ONEMI) released a list of the trapped miners on August 6, which included Franklin Lobos Ramírez, a retired footballer.

Chile is the worlds top producer of copper, according to The Economist. The San José Mine is owned by the San Esteban Mining Company (Empresa Minera San Esteban). The mine was closed down in 2007, after relatives of a miner who had died sued the company executives, but the mine was re–opened in 2008.

It was originally estimated that “it would take three to four months to complete the rescue of the trapped miners”. There were three plans to reach the miners: “Plan A” using a Strata 950 drill, “Plan B” using a Schramm T130XD drill, and “Plan C” using a RIG-422 drill. The first to reach the miners was “Plan B”, early on Saturday 9.

The last step of their rescue, announced by Health Minister Jaime Mañalich, was originally due to begin on Tuesday. Laurence Golborne, Minery Minister said “If it is possible, and the cement sets before and we don’t have any impediments to doing it, it would be wonderful,” in a press conference on Monday. The men will be extracted in a steel rescue capsule 54 cm (21 inches) in diameter.

On September 4, Chilean filmmaker Rodrigo Ortúzar announced plans to film a movie about the accident, called “Los 33” (“The 33”). The film will be released in 2011.

One miner is Bolivian, and the other 32 are Chilean.

Raúl Bustos, 40 years old, is an hydraulics engineer. He left his job in Talcahuano after the February 27 earthquake to work in the mine.

Daniel Herrera, 27 years old, is a lorry driver. He has acted as paramedic assistant in the mine. He said to La Tercera “the miners were unhappy with the psychologist in the rescue team.”

Claudio Acuña, miner, is fan of the Colo-Colo football club. The BBC reports he is aged 56, but El Comercio says he is 44.

Pedro Cortez is aged 24. He joined the mine with his friend Carlos Bugueño. Cortez is an electrician, and lost a finger in the mine a year ago.

On June 4, a report published by the United States Centers for Disease Control and Prevention (CDC) showed that in the past 16 years high school students have become less likely to engage in health risk-related behaviors such as having sex and taking drugs. However, the CDC found that Hispanic students were less likely to have reduced risky behavior when compared to Black and White students in several key areas.

The National Youth Risk Behavior Survey (YRBS) is run by the CDC every two years, and is an anonymous, self-administered survey of students in grades 9 to 12. In the 2007 YRBS, over 14,000 students were surveyed from across 44 U.S. states, 5 territories, and several individual school districts. The combined statistics used results from 39 states and 22 large urban school districts.

The survey showed that males were more likely than females to engage in most behaviors involving violence or risk of unintentional injury, including driving while drinking alcohol, carrying a weapon, and being involved in a physical fight, although females were more likely to have contemplated or attempted suicide. Males were also more likely to have smoked tobacco or marijuana, engaged in heavy drinking, or engaged in sexual intercourse, while females were more likely to have fasted for 24 hours or more, vomited or taken laxatives in order to lose weight.

While the proportions of White and Black students who had ever had sexual intercourse, and who had had sex with four or more partners in their lifetimes, all dropped over the period 1991-2007, there was no change in either of these statistics for the Hispanic population. Compared to their counterparts in the 1990s however, Hispanic students in 2007 were found to be more likely to have used a condom during their most recent sexual intercourse, and less likely to have consumed drugs such as cigarettes, alcohol and marijuana.

Hispanic students were more likely than White or Black students to go without food for 24 hours to lose weight, to take drugs such as heroin or cocaine, to drink alcohol on school property, and to have avoided school on occasion because of safety concerns.

In comparison with previous YRBS results, the survey found that the percentage of students who had ever had sexual intercourse decreased from 54.1% in 1991 to 47.8% in 2007, with a comparable decrease in the percentage who had had four or more sexual partners, from 18.7% to 14.9%. Decreases were also found in the percentage of students who had attempted suicide, who rode in a car with a driver who had been drinking alcohol, and who had smoked marijuana in the past month, but an increase in the percentage who had avoided school on occasion because of safety concerns (from 4.4% in 1993 to 5.5% in 2007).

“We are pleased that more high school students today are doing things that will help them stay healthy and avoiding things that put their health in danger. Unfortunately we are not seeing that same progress among Hispanic teens for certain risk factors,” said Howell Wechsler, Ed.D., MPH, director of CDC’s Division of Adolescent and School Health.

Wikinews accredited reporter William S. Saturn reached out to Unity Party of America presidential nominee Bill Hammons of Colorado to discuss Hammons’s 2020 campaign for President of the United States.

Hammons, a former Newsweek manager and owner of the website “Bill’s List”, founded the Unity Party in 2004 with supporters of General Wesley Clark’s unsuccessful campaign for the Democratic Party’s presidential nomination. The party, which describes itself as centrist, advocates in its constitution for, among other things, a balanced budget amendment, elimination of the federal income tax, tax deduction for health care costs, a global minimum wage for fair trade, term limits for Congress and judges, lowering the voting age, DC statehood, and expanded space exploration.

Hammons has grown the party with various campaigns for public office.  He ran for US Congress in 2008 and 2010, US Senate in 2014 and 2016, and for Governor of Colorado in 2018.  Last year, Hammons embarked on a presidential campaign and became the Unity Party’s first presidential nominee. Engineer Eric Bodenstab, the party’s 2018 nominee for Lieutenant Governor of Colorado was picked to be his running mate. Bodenstab spoke to Wikinews last August. The Hammons-Bodenstab ticket has qualified for ballot access in Colorado, Louisiana, and New Jersey.

With Wikinews, Hammons discusses his background, campaign, the COVID-19 pandemic, the U.S. Supreme Court, and Black Lives Matter, among other issues.

BHP Billiton Ltd says its underground Leinster nickel mine in Western Australia, where a contractor was killed in an explosion last week, will stay shut until the outcomes of a government investigation are released.

A BHP spokesman in Perth refused to estimate how long company and government officials will take to investigate the incident. “These investigations can go on for quite some time and the mine will remain closed for that same length of time, said Brian Watt. “But it’s difficult to speculate”

Watt declined to comment on how much damage the underground explosion caused to the mine, or how much time would be needed to bring the operation back on line once a decision to resume is made.

BHP Billiton have confirmed the death at the Leinster Nickel Operation, north of Kalgoorlie in Western Australia – 950 km north east of Perth. BHP said the incident occurred late in the afternoon of Friday, February 3.

Mark Quinn, 32, from Broken Hill in far western New South Wales and an employee of MacMahon’s, was fatally injured. He was working approximately 900 meters underground when an explosion occurred. BHP said in a media release that there were no other persons injured as a result of the incident.

The cause of the explosion is not yet known. Operations at Leinster have been stopped and employees at site are being briefed and counseled.

BHP Billiton is the world’s third largest nickel producer, with the Leinster mine producing up to 45,000 metric tons of nickel concentrates a year.

Following speculations that Leinster’s closure may lead to a nickel shortage, a spokesperson told Reuters that BHP Billiton had sufficient nickel concentrate stockpiled to last until the mine reopens.

The Western Australian government has described the fatality rate in the mining industry as “deplorable and atrocious”.

John Bowler, Western Australia’s Employment Protection Minister says he will consider implementing changes to improve the safety record of the mining industry. Mr Quinn’s death is the third underground fatality and the fourth mining death this financial year.

The new Minister, John Bowler, says he will consider implementing any changes needed to improve safety in the industry.

Ireland’s National Pensions Reserve Fund (NPRF) has posted a 2.4% return for the first quarter (9.6% annualized). On March 31, the funds value stood at €12.3bn, a rise of €290m (excluding state contributions) since December 31.

Donal Geaney, the fund’s chairman, told the press that growth in the past quarter had been driven by the Fund’s European equity investments.

Mr Geaney, former Élan CEO, has pursued a policy of diversification since February of this year, with the stated aim of placing a larger amount of the funds assets in companies with small market capitalizations and in property funds.

The fund was set up by the National Pensions Reserve Fund Act, 2000 to partially meet the expected rise in Irish pension costs from 2025 onwards.
