We briefly recap some of the stories appearing on Wikinews this week from around the world.

Thursday, April 11, 2019

Wikileaks founder Julian Assange, 47, today appeared at an extradition hearing in SPECIFIC COURT, London to determine whether he will be sent to the United States, where he faces charges of conspiracy to commit computer intrusion.

Assange, an Australian, was arrested April 11 in London at the Ecuadorean embassy, where he had been living in asylum since 2012. Assange faces legal issues in United Kingdom, the United States, and possibly Sweden for various alleged conspiracy, espionage, cyber, and sex crimes.

Ecuadorian president Lenin Moreno said he found Assange in violation of the terms of his asylum after it became clear he was still politically active with continued involvement in the Wikileaks operation. Assange’s actions within the embassy also became an issue. He allegedly threatened employees, interfered with embassy guards, installed surveillance equipment, and neglected his own hygiene. He also allegedly attempted to blackmail Moreno by threatening to release images, text messages, and other materials if Ecuador moved forward with nullifying his asylum status enlisting Ola Bini, as an alleged co-conspirator, and was arrested the same day.

UK authorities said the Ecuadorean government informed them Assange’s asylum had been revoked and formally allowed Metropolitan Police to enter the sovereign embassy for the arrest. Assange was first taken to a Central London Police Station and then transported to the Westminster Magistrates’ Court, where he pleaded not guilty to a 2012 failure to appear in court after a bail bond expired, carrying up to 12-months in prison. District Judge Michael Snow ultimately ruled Assange was guilty sending him to Southwark Crown Court for further sentencing.

US authorities have formally requested their UK counterparts for an extradition hearing currently scheduled for May 2, 2019, on an initial charge of one count of conspiracy to commit computer intrusion in connection with leaks of classified US documents starting in 2010. The US Department of Justice (DoJ) have compiled communications where an intelligence analyst identified as then-US Army Pvt. Chelsea Manning. Manning was later Court-martialed in 2013 and shown to have provided Wikileaks with 700,000 videos, documents, and other files compromising US intelligence and security. The US indictment of Assange alleges, “[Assange] agreed to assist Manning in cracking a password stored on United States Defense Department computers.”

The US DoJ may broaden the charges invoking the Espionage, Computer and Cybersecurity, Security and Secrecy Acts as extradition proceedings are formalized. Major areas of interest are the materials regarding the publication of emails and other electronic documents from the Democratic Nation Committee leaders like Hilary Clinton’s presidential campaign chair John Podesta. According to the Special Council’s report, Robert Mueller did determine the source was of Russian origin. Another incident of interest is the 2017 releases of US Central Intelligence Agency (CIA) hacking capabilities known as the “Vault 7” leak which enlisted a still not publicly known CIA employee.

Assange’s attorney, Barry Pollack, commented on the U.S. charges: “While the indictment against Julian Assange disclosed today charges a conspiracy to commit computer crimes, the factual allegations against Mr. Assange boil down to encouraging a source to provide him information and taking efforts to protect the identity of that source. Journalists around the world should be deeply troubled by these unprecedented criminal charges.”

Swedish authorities may also seek Assange’s extradition over rapes allegedly occurring in 2012 which was major factor in seeking asylum. Assange denied the allegations and the investigation was later dropped, but Swedish law permits the authorities there to re-open it before the Statute of Limitations runs out next year.

Leaked diplomatic cables between Australia and the US Secretary of State, Hillary Clinton, have raised controversy in the Australian community. The documents were released by the whistle-blowing website Wikileaks. The cables between the then prime minister of Australia, Kevin Rudd, and the US Secretary of State, Hillary Clinton, revealed that China may need to be forced to integrate into the international community. The secret documents also contained information of a conversation between Clinton and Rudd in Washington. In the interview, Rudd stated that China was “paranoid” about Taiwan and Tibet.

The sensitive documents may place a strain on diplomatic relations between Australia and China. Despite this, Kevin Rudd reassured the public that the “robust” relationship between Australia and China wouldn’t sustain any substantial damage to the relations between the two countries. At this stage, Prime Minister Julia Gillard has provided no further comment on the matter, other than to ensure that the relationship between China and Australia would allow opinions to be expressed without any threat to either side.

At the heart of the leaks is Australian founder, Julian Assange. Wikileaks have now released 821 of their promised 251,287 US diplomatic cables. The cables are being released on a stage-by-stage basis. Earlier this week, Assange was arrested on suspicion of rape in London under a Swedish arrest warrant placed on him from a court in Stockholm on November 18.

The Spanish word “tortuga” means “turtle.” But in the wake of the New Orleans disaster, the USS Tortuga is helping other animals.

For nearly two weeks now, sailors from Tortuga’s repair division have devoted much of their time during this disaster relief operation to ensure the health and comfort of displaced pets.

September 4th, just after the ship moored to a pier at Naval Support Activity (NSA) New Orleans, HT1(SW) Mark Hanley and DC1(SW) Antony Graves gathered materials from the repair shop on board to construct a kennel along the levee. The facility they made soon became a popular shelter for the homeless animals of the storm.

Tortuga’s search and rescue team brought aboard more than 170 displaced citizens during this past week, providing them with food, water, medical aid and a place to sleep.

Tortuga’s makeshift kennel, named ‘Camp Milo & Otis,’ has housed as many as 90 dogs, eight cats, one rabbit, one guinea pig, a pair of parakeets and a flightless pigeon during the past week of operation.

Currently, there are 14 dogs that remain in Tortuga’s care, as many of the other pets have been taken to animal shelters in the area for extra medical attention, or been claimed by their owners upon arrival to Tortuga. The pets that Tortuga has registered have all been in the hands of professional veterinarians assigned to provide expert medical attention to the members of Camp Milo & Otis.

Dr. Kelly Crowdis and Dr. Latina Gambles, both from Tuskegee University and Christian Veterinary Missions, have treated many of the pets for infection, dehydration, malnourishment and broken bones at the Camp during the past week.

“The animals were bathed and assessed before physical interaction with the sailors,” said Dr. Crowdis. “They’ve been given immunizations, antibiotics and medications based on their medical needs.”

Dr. Crowdis added, “What these sailors have done on their own has been such a heart-warming thing. As an animal lover, it is so comforting to know that everyone cares about the animals in addition to the human lives rescued from the storm. I’m very pleased with these guys for taking the initiative to construct this kennel.”

Graves, Hanley and other members of their division have consistently bathed, fed, walked and given special attention to every dog, every day.

“We play with them,” said Hanley. “We take them out of their kennels to give them attention every day. And we’ll continue to do that for as long as our ship’s mission keeps us here.”

September 11th, the Agricultural Center at Louisiana State University donated supplies to “Camp Milo & Otis” in support of Tortuga’s efforts to help the animal victims.

”We got medical supplies, bowls, food, cages, leashes, collars, toys, cat litter and cleaning supplies from these people yesterday,” said Graves. “It’s nice to know that so many people out there have heard about what our ship is doing, and responded by donating so much to support us the best they can.”

A photo gallery of unclaimed pets is on the USS Tortuga’s web site.

As part of disaster plans, the Department of Homeland Security has also deployed Veterinary Medical Assistance Teams to provide medical care to pets and livestock, as well as provide any needed veterinary medical care for search and rescue dogs.

There are over 3,850 animals being sheltered around the state. If someone is looking for a pet they should contact their nearest Humane Society or go online to http://www.petfinder.org// . More information is also available at http://www.vetmed.lsu.edu//.

This week, the Public Broadcasting Service aired a NOVA program titled “Dimming the Earth”, which presented research by leading scientists on the complex systems of our global climate and human activity’s effect on it. One of the largest interactions (or “inputs”) humans have with the atmosphere is the ever-increasing use of fossil fuels. Consumption has risen 2% per year for this decade.

Fossil fuels burnt in factories and automobiles send their waste into our atmosphere in two forms. The first is CO₂ and other greenhouse gases, which have received substantial attention in the last few years because of the way they trap heat in the atmosphere. The second is the tiny particles of sulfur dioxide, soot and ash, which scientists call aerosols (basically smog). Research into understanding the negative health effects of air pollution has resulted in the development of catalytic converters for cars as well as devices to remove particulate solids from industrial waste before it reaches the air.

More recently, atmospheric scientists have come upon the phenomenon of the reduction of direct sunlight reaching Earth’s surface— observing a nearly a 5% decline between 1960 and 1990, with evidence of a recovery since then. This has been dubbed the “global dimming” effect, and is probably due to the way these aerosols act upon clouds. It is important to realise that this does not represent a net loss of this much sunshine to the climate system – if so, large temperature declines would have been observed. Instead, the sunshine is absorbed elsewhere in the system, with a much smaller net loss.

Clouds form when moisture gathers around airborne particles, such as pollen or dust. Clouds formed by the aerosol particles emitted by fossil fuel consumption are made of many more tiny droplets than “natural” clouds. These smog-created clouds have two notable effects: they shield sunlight from reaching Earth’s surface and, due to water’s reflective nature, the millions of tiny droplets suspended in them reflect light back into space, allowing even less light to reach Earth.

Many scientists now believe that global dimming caused by these pollutants has mitigated the temperature rises brought about by global warming. Over the last thirty years, Earth’s temperature has increased by about 0.5 oC.

In the absence of global dimming, however, the Earth might be 0.3 oC warmer than it currently is, suggesting that a “tug-of-war” exists between greenhouse gases and particulates released by burning fossil fuels. Efforts to mitigate the human health dangers of smog have allowed more heat into our atmosphere and brought about a sharper increase in global warming.

Dr. James E. Hansen, professor at Columbia University and the head of the Goddard Institute for Space Studies [1], believes that if we continue on our current pattern, this warming could be as much as five degrees in the next thirty years and ten to fourteen degrees over the course of the century. Such a temperature rise would devastate life on Earth, likely bringing on a cascade of self-reinforcing warming effects. Earth’s forests drying and burning, a steady thawing of the Greenland and arctic ice sheets, and, most dangerous of all, a release of the methane hydrates that are now frozen at the bottom of the oceans, could remake the planet into something inhospitable to human life. Dr. Hansen warns that, according to his research, man has just 10 years to reduce greenhouse gases before global warming and other responses to human activity by Earth’s climate reach a “tipping point”, becoming unstoppable.

In findings published earlier this month in Ecological Applications, scientists from the University of Washington and Center for Ecosystem Sentinels examine the reason for the plummeting numbers of female Magellanic penguins, Spheniscus magellanicus, that have been reported at the birds’ breeding sites in South America over the past twenty years and more. Wikinews caught up with postdoctoral researcher and study co-author Natasha Gownaris to learn more.

In a press release, Gownaris said, “Two decades ago, there were about 1.5 adult male Magellanic penguins for every adult female at Punta Tombo[…] Today, it’s approaching three males for every female.” The findings suggested a disparity in the death rate of juvenile and adult penguins, rather than differences in chick survival, account for this difference.

Punta Tombo is one of the annual breeding sites for the species; it is in Argentina. The penguins travel thousands of miles each year to reach these sites.

The work involved building population models out of over thirty years of data collected by tagging individual penguins. Findings also suggested the pronounced sex disparity might make population models used to predict survival among other birds with a more even gender balance inappropriate for use on Megallanic penguins.

According to the data, since 1987, overall population of Magellanic penguins in Punta Tombo at one of their annual breeding sites in Argentina has declined 40%, while the male-to-female ratio has greatly increased.

Since 1983, the research team has been putting stainless steel bands on tens of thousands of chicks hatched at the Punta Tombo breeding site in Argentina, noting which juvenile and adult birds make it back to the site the next year and extrapolating how many lived and died. Among juveniles, there was a 17% survival rate for males and 12% for females. Among adults, it was 89% and 85%. These effects became compounded every year, reaching as high as six males to one female among older penguins.

The researchers noted implications for penguin conservation: Gownaris remarked, “Over the years, this team has helped preserve the land and waters around breeding colonies like Punta Tombo[…] But now we’re starting to understand that, to help Magellanic penguins, you have to protect waters where they feed in winter, which are thousands of miles north from Punta Tombo.”

Gownaris answered a series of questions for our correspondent.

((Wikinews)) What prompted your curiosity about Magellanic penguins?

Natasha Gownaris: I’ve wanted to be a marine scientist since I was a child, when I would collect sand crabs (Emerita talpoida) from local beaches in New York. I studied fish as a graduate student, but I have a pair of adopted parrots and I am generally fascinated by birds. Plus, penguins eat fish! Studying penguins seemed like a great way to merge my love for the ocean and my love for birds. Penguins and other seabirds are also important to study because they tell us something about the health of the ocean ecosystems they feed in, similar to the use of canaries to test air quality in coal mines. Unfortunately, the decline of many seabird species worldwide is yet another warning sign of the negative and widespread impacts humans are having on the ocean.

((WN)) How did you approach putting together such a large-scale study?

NG: This study started in 1982, long before my joining the lab in March of 2016. Dr. Dee Boersma began this study as a response to a Japanese company’s interest in harvesting penguins for their skin, meat, and oil. Although the project has evolved over time, Dr. Boersma had the foresight to start banding chicks in 1983 and to set up a standard protocol that we follow each year. Since then, over 44,000 chicks have been banded at Punta Tombo. We’ve been able to follow some individuals for 30+ years, collecting detailed information on things like how often they breed and how many mates they’ve had.

((WN)) How much time did you end up spending in Argentina? What was it like at the breeding site?

NG: Members of the Boersma lab and volunteers spend approximately six months each year at Punta Tombo. I was fortunate enough to spend nearly four months at the colony between 2015 and 2017. It’s an incredible, otherworldly place. Magellanic penguins nest in burrows or bushes, and some areas of the colony are so dense with burrows that you feel like you’re on a different planet. The colony has declined by over 40% since the study started…so I can’t even imagine what it was like in the 1980s. My favorite time of the day is around 8PM, when (hopefully fat) penguins are returning to the colony en masse after a foraging trip. They are also most vocal in the morning and evening, making their characteristic braying sound— the related African penguin earned the name “jackass penguin” because they sound a bit like donkeys. The colony is also full of other beautiful and interesting creatures, including a llama-like species called the guanaco and an ostrich-like species called the rhea.

((WN)) Do you have any theories on why more female juveniles die at sea? You mention starvation; what might be the causes of that, and are there other possible explanations you can think of?

NG: We are not yet certain why females are more likely to die, but we think it must be related to their smaller body size. Because the mortality is most uneven in juveniles, higher mortality doesn’t seem to be related to greater costs of breeding for females than for males. Female Magellanic penguins are about 17% lighter than males and have smaller bills. We think that, because of this size difference, females have a lower storage capacity, can’t dive as deep, and can’t take as wide a range of prey as males — all disadvantages when faced with limited and unpredictable food resources. These disadvantages hit juvenile females even harder, as juveniles are still learning how to forage and often travel further than adults do in the non-breeding season. Counts of carcasses in the species’ migration range support starvation as the main cause of female-biased mortality; while oiled carcasses have a sex ratio of 1:1, females outnumber males in carcasses of starved birds. The only other possibility is that females are moving to other colonies at higher rates than are males, but this species is known to almost always return to its natal colony to breed.

((WN)) You suggest conservation efforts should look at protection of feeding grounds. What sort of measures do you think might be beneficial?

NG: Because penguins migrate such long distances over the non-breeding season, a mixture of tools (including no-take marine protected areas and traditional fisheries management tools, like catch limits) is likely to be needed. Although there is currently some spatial protection surrounding the species’ breeding colony, this protection does not extend to their migratory route. And, of course, everyone can contribute to penguin conservation by reducing their plastic waste, making more sustainable food choices, and reducing their carbon footprint.

((WN)) What do you think might be causing pressure on food sources for the penguins?

NG: The two main threats to the food sources of this colony are climate change, which cause shifts in primary productivity and fish stocks, and fisheries. Fisheries compete with penguins for fish species such as hake and anchovy.

((WN)) Have you noticed differences in behavior among the penguins as the ratios become increasingly skewed?

NG: In a separate study currently under review, we have shown that aggression between males of Magellanic penguins is higher when the sex ratio at the colony is more skewed towards males. We also showed that nearly all females at the colony breed but that, over time, fewer and fewer males find mates. Single male penguins sometimes intrude [on] nests of mated pairs and interrupt the incubation of eggs or feeding of chicks, leading to mortality. In some cases, they will even attack and kill chicks.

((WN)) Your release mentioned sexing the penguins was problematic; how did you achieve it with confidence?

NG: We have some methods of sexing penguins that we feel confident about — using genetics or measures of cloaca size around egg laying, for example. However, these methods are time intensive, so we have also developed visual cues for sex penguins (bill size, behavior, forehead shape). We looked at individuals that had been sexed using both a certain method (e.g. genetics) and visual methods to calculate how often we got it right based on visual cues alone and found that we have very high accuracy. We also used statistical tools to help to deal with uncertainty in the sex of some individuals.

((WN)) How well can you extrapolate population trends at Punta Tombo based on the birds you tagged? More broadly, how well do you think this work represents global populations?

NG: It is likely that females have higher mortality than males at other colonies of this species and in other penguin species. We unfortunately do not have enough information from other colonies of this species (e.g. sex ratio and population trends) for an accurate global assessment of population trends. We do know that some colonies of the species are growing but that, at the global level, the species is still in decline.

((WN)) In your opinion, for how much longer are penguin populations sustainable without intervention?

NG: This is nearly impossible to answer without more information on other colonies of the species, but the Punta Tombo colony is declining rapidly. We estimate declines of at least 43% since 1987 from our annual surveys at the colony, but it is likely that actual declines are higher because of the increasingly skewed sex ratio.

((WN)) What are your next plans moving forward with your work?

NG: We are currently studying the sex ratio in Magellanic penguin chicks (at hatching and at fledging) to determine how this influences the sex ratio in adults. There are two priorities moving forward — 1) estimating sex ratio at other colonies of this species and determining whether females are more likely to leave Punta Tombo for other colonies than are males and 2) determining the mechanisms underlying lower female survival, e.g. by studying the foraging behavior and diet of males and females and the individual characteristics (like body size) that correlate with survival.

A story about a man carrying over 30,000 (sometimes reported as 40,000) volts of static electricity in his body, allegedly generated by a wool sweater and nylon jacket combination, is circulating through major news outlets. The story, carried first by the Warrnambool Standard, says that the man, Frank Clewer, a 58-year old cleaner from Dennington, involuntarily created a scene by causing fire departments to evacuate three buildings where he had left his mark, before he realized he was causing the burn marks on carpets and allowed the fire department to help him.

The story has been picked up by The Register, Guardian, BBC, USA Today, Reuters, local agencies of ABC, the San Francisco Chronicle, and other news outlets.

Several unanswered objections mark the story as a possible hoax:

• Clewer enters and exits his car several times in the story — if he opened the car by touching its presumably metal lock, he would surely release some electricity into the car through his hand; everyone has at some point experienced the painful shock of touching a door handle or car keys to a lock. Though the car might not be grounded, it would still be at a lower potential and thus energy would be transferred. This would be noticeable; the story does not comment that Clewer understood what was happening to him.
• Firefighters supposedly “used a device to check static electricity on him and his belongings.” While firefighters would be likely to carry a high-voltage multimeter around to measure the current and voltage ratings of downed power lines, it is unlikely that the same device could measure such a large voltage resulting from a very small amount of static energy without de-electrifying it.
• For such a large voltage to be stored, humidity would have to have been extremely low on that day for the air around him not to ionize and source current, removing the static energy.
• If he was carrying such a large voltage, his hair would probably have stood on end, as this is a notable effect when one touches a Van de Graaf generator. Note: It is uncertain at what voltage this effect begins, and since Van de Graaf machines routinely exceed Megavolts of electric potential, this may not be a verifiable objection.
• This statement: “Firefighters took possession of Clewer’s jacket and stored it in the courtyard of the fire station, where it continued to give off a strong electrical current.” (Reuters UK) First, there is no reason they would need to take possession of the jacket — the static electricity could be dealt with by simply dumping water on it. Second, the jacket could not “give off” an electric current without some continuous source of energy, which, in storage, is impossible. It is possible that the jacket could hold a voltage, but the effects of this would not be visible — if they were, they would be short-lived as the jacket would lose its static energy. In any event, the current would be miniscule.
• The amount of energy stored on Clewer’s person and possessions could not have been more than a few Joules; this is unlikely to have burned carpet.

The equation for stored energy in capacitors is:

Where U = energy, C = capacitance, and V = voltage. A human body by itself typically has a capacitance of around 250 pF, which would mean a voltage of 30,000 V would produce energy of 0.11 joules. Even if Clewer’s possessions resulted in a parallel capacitance of 1 microfarad, this would still only result in an energy storage of 450 J. This amount of energy would be insufficient to burn carpet or char plastic, although a spark could ignite flammable vapor or gas.
