Nokia agrees to buy Siemens' stake in NSN joint venture: Bloomberg

(Reuters) - Mobile handset maker Nokia has reached a deal to buy German industrial conglomerate Siemens' stake in their telecoms equipment joint venture, Nokia Siemens Networks, Bloomberg reported on Sunday, citing three people familiar with the situation.

The deal, which will see Nokia pay less than 2 billion euros ($2.60 billion) for Siemens' 50 percent stake in the joint venture, could be announced as soon as Monday, Bloomberg reported.

Nokia will use a bridge loan to help finance the purchase, Bloomberg said.

Nokia, Siemens and NSN could not be reached for comment outside regular business hours.

A founding six-year pact binding Siemens and Nokia in NSN expired in April and both companies have been looking to exit the joint venture through a buyout or public offering.

Earlier this month, three sources familiar with the matter said Siemens was seeking offers from private equity firms to buy its stake in the joint venture which has shown signs of a turnaround in recent quarters, helped by a massive restructuring drive last year.

Altitude sickness may hinder ethnic integration in the world's highest places

July 1, 2013 ? Ethnic segregation in nations straddling the world's steepest terrains may be reinforced by the biological tolerance different peoples have to altitude, according to one of the first studies to examine the effect of elevation on ethnic demographics.

Research from Princeton University published in the journal Applied Geography suggests that people native to low-lying areas can be naturally barred from regions such as the Tibetan Plateau, the Andes or the Himalayas by altitude sickness, which is caused by low oxygen concentration in the air and can be life-threatening. As a result, the homogeny of the local population can increase with elevation. In nations shared by people of high- and lowland extractions, this separation can potentially increase ethnic tension.

The researchers studied Tibet and found that elevation has heavily influenced the location of the surrounding region's population of Han Chinese, who make up 92 percent of China's population and originate from the country's eastern plains. Tibet has an average elevation of roughly 14,370 feet (4,380 meters) above sea level. The number of settlements with a large Han Chinese population peaks at around 8,900 feet (2,700 meters), while Tibetan settlements only begin to peter out beyond 17,000 feet (5,200 meters), the researchers found. The researchers attribute the sudden drop in the Han Chinese population to altitude sickness, and cite existing research showing that Han Chinese are indeed susceptible to altitude sickness in areas in which Tibetans thrive.

First author Christopher Paik, who undertook the study as a postdoctoral research scholar in the Empirical Studies of Conflict Project in Princeton's Woodrow Wilson School of Public and International Affairs, said that the research adds a new dimension to the study of how terrain influences demographic patterns. The field already explores the role of factors such as soil quality and access to the sea. The biological effects of elevation make altitude a particularly objective and reliable measurement for helping determine and understand how populations around the world's highest areas form, he said.

"There is very little research about the effect of altitude on migration patterns," said Paik, who is now an assistant professor of politics at New York University Abu Dhabi. "One of the nice things about using this geographical indicator as an independent variable is that there isn't any human intervention in determining the altitude of the region because it's established by nature.

"Rather than saying there is merely a correlation between settlement patterns and altitude, our research takes it one step further and suggests that altitude can directly determine the settlement patterns we see today. There's a causal story here," Paik said.

The separation that results from these settlement patterns could result in greater ethnic friction, Paik said. He initiated the current study in the wake of the 2008 unrest in Tibet, a series of protests that lead to imprisonment, detainment and clashes with Chinese security forces. Paik noticed that the most violent outbreaks occurred in areas of Tibet with the lowest relative concentrations of Han Chinese -- regions that also have the highest elevations. (Paik is currently working on a paper that correlates lower levels of violence during the 2008 unrest with lower elevation and greater Tibetan/Han integration.)

Paik and co-author Tsering Shawa, who heads the Digital Map and Geospatial Information Center in Princeton's Lewis Library, used 2000 Chinese census data to determine the Han population in settlements within the traditional Tibetan homeland, which includes the Tibetan Autonomous Region as well as portions of the Chinese provinces Qinghai, Gansu, Sichuan and Yunnan. They also gauged past Han Chinese presence through maps and a database developed by Shawa that indicate whether the official name of the 1,960 settlements in this area is Han Chinese, Tibetan or both.

The researchers found a similar distribution pattern of towns where at least one-third of the population are Han Chinese and traditional Han settlements (most of which date as far back as the 13th century) -- the bulk are located lower than 8,900 feet above sea level. No towns with a Chinese name exist above 15,000 feet (4,600 meters). Meanwhile, the greatest number of settlements with a Tibetan name stands at an only slightly lower elevation of 14,760 feet (4,500 meters), an area that the census shows has a minimum of Han Chinese inhabitants.

"What the outcome suggests is that there is a direct effect of altitude now as well as in historical settlement patterns," Paik said. "On the one hand there are settlements where Han Chinese came 1,000 years ago and established roots in that region, which makes it easier for migrants to come in. That provides a channel through which more Chinese live there today because their ancestors lived there as well.

"But if historical settlement is the only channel through which altitude influenced current settlement patterns, then there wouldn't be the direct influence of elevation through altitude sickness that we still see," Paik said. "Han Chinese still suffer from altitude sickness and the influence on settlement seems to persist today."

Paik and Shawa reference at least 10 studies that delve into the genetic adaption of Tibetans' blood cells and lung tissue to the low-oxygen conditions of a life on high -- a tolerance research suggests they share with Andes dwellers in countries such as Bolivia.

Han Chinese do not enjoy this predisposition even in modern times. The researchers cite a 2009 paper in the journal Clinica Chimica Acta that explored the genetic susceptibility of Han Chinese laborers to the pulmonary edema -- potentially fatal fluid buildup in the lungs -- they experienced during construction of the Qinghai-Tibet railway completed in 2005.

"The main contribution of this research is to point out geography does matter in ethnic demographic patterns," said Enze Han, an assistant professor of politics and international studies at the University of London. Han, who had no role in the research but is familiar with it, agrees with the researchers when they write that modern technology and transportation makes migration into high-altitude lands easier.

But, Paik said, the population distributions he and Shawa document show that geography -- via altitude sickness -- continues to play a strong role in regional diversity despite modern trappings such as the Qinghai-Tibet railway and government initiatives such as China's Western Development Program.

"Ethnic integration policy seems to work in the long run, but it will be harder to implement in the higher altitude regions," Paik said. "There seems to be a strong enough influence of altitude on settlement patterns such that even if you try to have integration happening there, nature works against those initiatives."

Egypt: Protesters gather to demand Morsi's ouster

CAIRO (AP) ? Tens of thousands of opponents of Egypt's Islamist president massed in Cairo's Tahrir Square and in cities around the country Sunday, launching an all-out push to force Mohammed Morsi from office on the one-year anniversary of his inauguration. Fears of violence were high, with Morsi's Islamist supporters vowing to defend him.

Waving Egyptian flags, crowds packed Tahrir, the birthplace of the 2011 uprising that toppled autocrat Hosni Mubarak, and chants of "erhal!", or "leave!" rang out.

On the other side of Cairo, thousands of Islamists gathered in a show of support for Morsi outside the Rabia al-Adawiya Mosque near the Ittihadiya presidential palace, which the opposition planned to march on in the evening. Some Morsi backers wore homemade body armor and construction helmets and carried shields and clubs ? precautions, they said, against possible violence.

There is a sense among opponents and supporters of Morsi that Sunday is a make-or-break day, hiking worries that the two camps will come to blows, even as each side insists it won't start violence. Already at least seven people, including an American, have been killed in clashes the past week, mainly in Nile Delta cities and the coastal city of Alexandria.

The demonstrations are the culmination of polarization and instability that have been building since Morsi's June 30, 2012 inauguration as Egypt's first freely elected leader. The past year has seen multiple political crises, bouts of bloody clashes and a steadily worsening economy, with power outages, fuel shortages, rising prices and persistent lawlessness and crime.

In one camp are the president and his Islamist allies, including the Muslim Brotherhood and more hard-line groups. They say street demonstrations cannot be allowed to remove a leader who won a legitimate election, and they accuse Mubarak loyalists of being behind the campaign in a bid to return to power. They have argued that for the past year remnants of the old regime have been sabotaging Morsi's attempts to deal with the nation's woes and bring reforms.

Hard-liners among them have also given the confrontation a sharply religious tone, denouncing Morsi's opponents as "enemies of God" and infidels.

On the other side is an array of secular and liberal Egyptians, moderate Muslims, Christians ? and what the opposition says is a broad sector of the general public that has turned against the Islamists. They say the Islamists have negated their election mandate by trying to monopolize power, infusing government with their supporters, forcing through a constitution they largely wrote and giving religious extremists a free hand, all while failing to manage the country.

The opposition believes that with sheer numbers in the street, it can pressure Morsi to step down ? perhaps with the added weight of the powerful military if it signals the president should go.

"Today is the Brotherhood's last day in power," predicted Suliman Mohammed, a manager of a seafood company who was protesting at Tahrir, where crowds neared 100,000 by early afternoon.

"I came here today because Morsi did not accomplish any of the (2011) revolution's goals. I don't need anything for myself, but the needs of the poor were not met."

Another Tahrir protester, 21-year-old Mohammed Abdel-Salam, said he came out because he wanted early presidential elections. "If he is so sure of his popularity why doesn't he want to organize early elections? If he wins it, we will tell the opposition to shut up."

Underlining the potential for deadly violence, a flurry of police reports on Sunday spoke of the seizure of firearms, explosives and even artillery shells in various locations of the country, including Alexandria and the outskirts of Cairo. Sunday afternoon, two offices belonging to the Brotherhood's Freedom and Justice party, were attacked and ransacked Sunday by protesters in the city of Bani Suef, south of Cairo.

In an interview published Sunday in The Guardian, Morsi ? who has three years left in his term ? said he had no plans to meet the protesters' demand for an early presidential election.

"If we changed someone in office who (was elected) according to constitutional legitimacy ? well, there will (be) people or opponents opposing the new president too, and a week or a month later, they will ask him to step down," Morsi told the British daily.

"There is no room for any talk against this constitutional legitimacy," he said.

Traffic in Cairo's normally clogged streets was light at midday as many residents chose to stay home for fear of violence or a wave of crime similar to the one that swept Egypt during the 18-day, anti-Mubarak uprising. Banks were closing early and most government departments were either closed for the day or were thinly staffed. Most schools and colleges are already closed for the summer holidays.

The opposition protests emerge from a petition campaign by a youth activist group known as Tamarod, Arabic for "Rebel." For several months, the group has been collecting signatures on a call for Morsi to step down.

On Saturday the group announced it had more than 22 million signatures ? proof, it claims, that a broad sector of the public no longer wants Morsi in office.

It was not possible to verify the claim. If true, it would be nearly twice the around 13 million people who voted for Morsi in last year's presidential run-off election, which he won with around 52 percent of the vote. Tamarod organizers said they discarded about 100,000 signed forms because they were duplicates.

Morsi's supporters have questioned the authenticity and validity of the signatures, but have produced no evidence of fraud.

Adding to his troubles, eight lawmakers from the country's interim legislature announced their resignation Saturday to protest Morsi's policies. The 270-seat chamber was elected early last year by less than 10 percent of Egypt's eligible voters, and is dominated by Islamists.

A legal adviser to Morsi also announced his resignation late Saturday in protest of what he said was Morsi's insult of judges in his latest speech on Wednesday.

A week ago, with the public sense of worry growing over the upcoming confrontation, Defense Minister Gen. Abdel-Fattah el-Sissi last week gave the president and his opponents a week to reach a compromise. He warned that the military would intervene to prevent the nation from entering a "dark tunnel."

Army troops backed by armored vehicles were deployed Sunday in some of Cairo's suburbs, with soldiers, some in combat gear, stood at traffic lights and major intersections. Army helicopters flew over Cairo on several occasions on Sunday, adding to the day's sense of foreboding.

Morsi had called for national reconciliation talks in a Wednesday speech but offered no specifics. Opposition leaders dismissed the call as cosmetics.

Asked by The Guardian whether he was confident that the army would not intervene if the country becomes ungovernable, Morsi replied, "Very."

The Egyptian leader, however, said he did not know in advance of el-Sissi's comments last week.

Discovery sheds light on why Alzheimer's drugs rarely help

July 1, 2013 ? The Alzheimer's Association projects that the number of people living with Alzheimer's disease will soar from 5 million to 13.8 million by 2050 unless scientists develop new ways to stop the disease. Current medications do not treat Alzheimer's or stop it from progressing; they only temporarily lessen symptoms, such as memory loss and confusion.

Current Alzheimer's drugs aim to reduce the amyloid plaques -- sticky deposits that build up in the brain--that are a visual trademark of the disease. The plaques are made of long fibers of a protein called Amyloid ?, or A?. Recent studies, however, suggest that the real culprit behind Alzheimer's may be small A? clumps called oligomers that appear in the brain years before plaques develop.

In unraveling oligomers' molecular structure, UCLA scientists discovered that A? has a vastly different organization in oligomers than in amyloid plaques. Their finding could shed light on why Alzheimer's drugs designed to seek out amyloid plaques produce zero effect on oligomers.

The UCLA study suggests that recent experimental Alzheimer's drugs failed in clinical trials because they zero in on plaques and do not work on oligomers. Future studies on oligomers will help speed the development of new drugs specifically aiming at A? oligomers.

The study was published as Paper of the Week in the June 28 issue of the peer-reviewed Journal of Biological Chemistry.

This Life-Size Lego Alien Facehugger Will Haunt Your Dreams

Carlos Valero is the brilliant mind behind this functional, life-size and creepy-as-hell Lego Alien Facehugger. This MOC 1:1 scale model uses only 500 bricks, and is so beautifully-accurate it would make Giger blush.

This Life-Size Lego Alien Facehugger Will Haunt Your Dreams

Considering that Alien is one of the best (if not the best) Sci-Fi horror films ever made, it's fitting that it gets some Lego love. Perhaps if the stars aligned and the Lego gods looked favorably upon us, perhaps one day an official Alien set could be released. Unfortunately, that will likely never happen, because Lego doesn't want its toys endorsing violent behavior. But how amazing would an egg-laying Alien Queen set be? Perched on her biomechanical throne, with cute, little minifig victims waiting to be implanted with a Xenomorph embryo, by parasitoid facehuggers...but I digress.

If you want to see another impressive Lego Alien homage check out this beautifully-detailed build of the Nostromo transport ship.

No Cold War duel with China in Africa: Obama

US President Barack Obama on Friday played down talk of great power rivalry in Africa, welcoming investment by the likes of China and rejecting the idea of Cold War-style proxy economic duel.

However, Obama, speaking aboard Air Force One as he flew to Johannesburg, South Africa, from Dakar, Senegal, did make a strong case for the US model of investment, which prioritizes local capacity building, democracy and good governance.

?I think it?s a good thing that China and India and Turkey and some of these other countries ? Brazil ? are paying a lot of attention to Africa,? Obama said. ?This is not a zero-sum game. This is not the Cold War. You?ve got one global market, and if countries that are now entering into middle-income status see Africa as a big opportunity for them, that can potentially help Africa.?

Obama said the model was ?greatly preferable? for a country like Senegal, where he started his three-nation tour and announced a new partnership to boost agriculture and fight poverty and hunger.

?In my discussions, a lot of people are pleased that China is involved in Africa. On the other hand, they recognize that China?s primary interest is being able to obtain access for natural resources in Africa to feed the manufacturers in export-driven policies of the Chinese economy,? he said. ?And oftentimes that leaves Africa as simply an exporter of raw goods, not a lot of value added ? as a consequence, not a lot of jobs created inside of Africa and it does not become the basis for long-term development.?

Chinese trade with Africa soared to US$200 billion last year.

In March, Chinese President Xi Jinping (???) visited Africa and Russia on his first foreign trip signing a raft of business and energy deals signaling Beijing?s intent to deepen ties further.

Obama said that the involvement of emerging powers in Africa was a sign of the continent?s economic potential and new vitality, but also a warning to the US that it cannot afford to stay on the sidelines.

Obama?s tour, also including Tanzania, is meant to make up for lost time, as the son of a Kenyan who became the first black US president made only one brief stop in sub-Saharan Africa ? in Ghana ? during his first term.

He is bringing with him some of his top economic advisers and executives from blue-chip US firms to drive new US investment and business links with the continent.

Yesterday, top Obama aide Valerie Jarrett and US Trade Representative Mike Froman were to hold a breakfast meeting with executives from firms including Coca-Cola, Ford Motor Co, the Development Bank of South Africa, the Carlyle Group, Goldman Sachs International and the African Finance Corp.

?One of the main things that we want American companies to see is that Africa is ready to do business and that there?s huge potential there,? Obama told reporters.

?What African countries have to do ... is ensure that there?s stability and good governance so that American companies can reduce some of those risks that have nothing to do with business and have to with, will they be able to get their profits out?? he added.
