New Deadly HIV
Russian scientists say that they have discovered a new and extremely virulent strain of HIV in Siberia. Announcing their discovery on Oct. 16, researchers at Novosibirk's Koltsovo science city say the HIV subtype, known as 02_AG/A, may be the most virulent form of HIV in the country. In a report in the
Naukograd Press, it explained that the HIV variant is believed to be capable of spreading at a much faster rate than subtype A(I), which, according to researchers, is Russia's current leading HIV strain. The new subtype, which researchers say was first detected in the city of Novosibirsk in 2006, is said to be spreading through some parts of Siberia at an alarming rate. In the Novosibirsk area, it is now said to account for more than half of all new HIV infections. Citing the scientists' statement,
RIA Novosti writes that the " number of HIV-positive people living in the Novosibirsk region has leaped from about 2,000 in 2007 to about 15,000 in 2012." Outside of Siberia, the subtype also may have been detected in Chechnya and parts of Central Asia, according to the
Naukograd Press. Though rates of HIV infections have been falling world-wide, Eastern Europe and Central Asia remain the only regions on the planet where HIV prevalence is on the rise says the United Nations. According to
RIA Novosti, 52%
of the HIV-positive people that live across that area are in Russia. The WHO says that intravenous drug use and sexual transmission remain the main driving forces behind the HIV epidemic in Eastern Europe and Central Asia. Lack of funding for HIV prevention and low coverage of HIV treatment services are fueling the high rates of AIDS-related deaths and rise of HIV infections as well.

Exercise Improves Academic Performance
Intensive exercise improves the academic performance of teenagers, according to new research. The study, of about 5,000 children, found links between exercise and exam success in English, mathematics and science. It found an increase in performance for every extra 17 minutes boys exercised, and 12 minutes for girls. The study by the U.K. University of Strathclyde and the University of Dundee found physical activity particularly benefited girls' performance at science. The authors said this could be a chance finding or reflect gender differences in the impact of physical activity on the brain. Children who carried out regular exercise, not only did better academically at 11 but also at 13 and in their exams at 16, the study suggested. Most of the teenagers' exercise levels were found to be well below the recommended 60 minutes a day. The authors speculated what might happen to academic performance if children got the recommended amount. They claimed that since every 15 minutes of exercise improved performance by an average of about a quarter of a grade, it was possible children who carried out 60 minutes of exercise every day could improve their academic performance by a full grade, for example, from a C to a B, or a B to an A. However, the authors admitted this was speculation given that very few children did anywhere near this amount of exercise. Dr. Josie Booth, one of the leaders of the study, from Dundee University said, Physical activity is more than just important for your physical health. There are other benefits and that is something that should be especially important to parents, policy-makers and people involved in education. The authors of the study, published in the British Journal of Sports Medicine, said further research backing the findings could have implications for public health and education policy. The study was funded by a grant from the BUPA Foundation to the University of Strathclyde.

Pollution Causes Cancer
Pollutants in the air we breathe have been classed as a leading environmental cause of cancer by the World Health Organization. It said the evidence was clear that it causes lung cancer. Sources of pollution include car exhausts, power stations, emissions from agriculture and industry as well as heating in people's homes. The WHO said the classification should act as a strong message to governments to take action. The International Agency for Research on Cancer (IARC), a part of the WHO, has now classed air pollution in the same category as tobacco smoke, UV radiation and plutonium. It said air pollution had been known to cause heart and lung diseases, but evidence had now emerged that it was also causing cancer. Said IRAC doctor, Kurt Straif, The air we breathe has become polluted with a mixture of cancer-causing substances. We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths The IARC said the most recent data suggested 223,000 deaths from lung cancer around the world were caused by air pollution. More than half of the deaths were thought to be in China and other East Asian countries. Rapid industrialization has led to smoggy skies in cities such as Beijing. However, it is a global problem and concerns about air pollution were raised in Europe again in October, 2013. Data suggests there may also be a link with bladder cancer. Dr. Julie Sharp, the head of health information at the charity, said, It's important that people keep the risk from air pollution in perspective. Although air pollution increases the risk of developing lung cancer by a small amount, other things have a much bigger effect on our risk, particularly smoking. Dr. Rachel Thompson, head of research interpretation at the World Cancer Research Fund International, said, This latest evidence confirms the need for government, industry and multinational bodies to urgently address environmental causes of cancer. But there's also a lot we can do as individuals to lower our chances of developing the disease such as being more physically active and adopting a healthier diet.

Human Bones Found in House
A cleaning crew and a realtor recently made a haunting discovery when they stumbled upon a possible occult altar forgotten for a decade and a half in a small house for sale in a Colorado, U.S.A., suburb. Animal skulls, chains, bones from a goat and possibly other animals, a skull mask with a black hood, candles and a machete were among the items that were found in the home's backyard shed. Police say that some of the bones, including a partial skull, are suspected of being human and have been sent to an out-of-state lab to determine whether any DNA evidence can be found. Up to 20 bones were found and investigators even brought in search dogs trained to find decomposing bodies. Neighbor Carlos Fraire said the discovery was very eerie. It's weird that it's this time of year, right around Halloween, Fraire told
9 News. According to a report by
Westword, neighbors described the woman who lived there as a Christian and the items in the shed are suspected of having belonged to her now-deceased husband, who reportedly left the country in 1998. For the last 15 years, his wife apparently either hadn't known the items were there or left them completely alone because when they were discovered most were covered in thick dust. The two split up over a decade ago, and the altar wasn't discovered until a realtor commissioned a cleaning crew so the house could be put up for sale. When the cleaners found the bones and a partial skull in the shed, they called the police.
It just appears that they were used in some type of 'occult' ceremony. At this point we have no evidence to suspect that any kind of crime has been committed, Lakewood Police Department spokesman Steve Davis said. Police say they have talked with at least one family member of the man who lived there who indicated he was an occultist. Investigators are not currently treating the home as a crime scene because human bones can be purchased on line in the U.S.

Amazon Rain Forest Drying Up
The Amazon rain forest's dry season lasts three weeks longer than it did 30 years ago, and the likely culprit is global warming, a new study finds. Rain falls year-round in the Amazon, but most of the annual deluge drops during the wet season. (The rainy season's timing varies with latitude.) Scientists think that a longer dry season will stress trees, raising the risk of wildfires and forest dieback. The forest’s annual fire season became longer as the dry season lengthened, according to the study, published on October 21, 2013, in the journal
Proceedings of the National Academy of Sciences.
The length of the dry season in the southern Amazon is the most important climate condition controlling the rain forest, Rong Fu, a climate scientist at The University of Texas at Austin's Jackson School of Geosciences, said in a statement.
If the dry season is too long, the rain forest will not survive. The new findings forecast a more parched future for the Amazon rain forest than the climate report released last month by the Intergovernmental Panel on Climate Change (IPCC), the study authors said. The IPCC models predict the Amazon dry season will last three to 10 days longer by 2100. But with the dry season already spanning an extra week each decade since 1979, the Texas team said the future effects will be more severe.
The dry season over the southern Amazon is already marginal for maintaining rain forest, Fu said.
At some point, if it becomes too long, the rain forest will reach a tipping point. Global warming can limit tropical rainfall across the southern Amazon in two ways, Fu explained. First, shifts in the southern jet stream can block cold fronts that trigger rainfall. (In the Northern Hemisphere, extremes in the northern jet stream pattern have been linked to wacky weather, such as the unusually warm winter in 2012.) Rising surface temperatures, attributed to global warming, also make it harder for storms to start. The heat inhibits "convective energy," keeping warm, dry air near the surface from rising and mixing with cool, moist air above. Half of the world’s oxygen is supplied from the trees in the Amazon rain forest.

Baldness Cure Possible
Scientists say they have moved a step closer to banishing bald spots and reversing receding hairlines after human hair was grown in the laboratory. A joint UK and US team was able to create new hairs from tissue samples. Far more research is needed, but the group said its technique had the "potential to transform" the treatment of hair loss. The study results were published in the journal Proceedings of the National Academy of Sciences. There are baldness therapies including drugs to slow the loss of hairs, and transplants, which move hair from the back of the head to cover bald spots. The scientists at the University of Durham, in the UK, and Columbia University Medical Centre, in the US, were trying to actually grow new hairs. Their plan was to start with material taken from the base of a hair and use it to grow many new hairs. But, human hair has been tricky to grow despite successes in animal studies. Whenever human tissue was taken from the dermal papillae, the cells which form the base of each hair follicle, the cells would transform into skin instead of growing new hairs. However, the group found that by clumping the cells together in "3D spheroids" they would keep their hairy identity. Tissue was taken from seven people and grown in 3D spheroids. These were then transplanted into human skin which had been grafted on to the backs of mice. After six weeks, new hair follicles formed in five out of the seven cases and some new tiny hairs began to form. Prof Colin Jahoda, from Durham University, told the BBC a cure for baldness was possible but it was too soon for men to be hanging up the toupee. It's closer, but it's still some way away because in terms of what people want cosmetically they're looking for re-growth of hair that's the same shape, the same size, as long as before, the same angle. Some of these are almost engineering solutions. Yeah I think it [baldness] will eventually be treatable, absolutely. He added, It's hard to say exactly how long that would take, but the fact that we've done it now should reawaken interest. Any future therapy would involve transplanting cells which have been grown in the laboratory so safety is a concern. There would be a risk of infection and the cells could become abnormal, or even cancerous, while being grown. Baldness cures may not be the first application of the research. Professor Jahoda believes the findings will be used to improve the quality of skin grafts used after severe burns. Professor Angela Christiano, from Columbia University, said, This approach has the potential to transform the medical treatment of hair loss. Current hair-loss medications tend to slow the loss of hair follicles or potentially stimulate the growth of existing hairs, but they do not create new hair follicles. Our method, in contrast, has the potential to actually grow new follicles using a patient's own cells.

Baldness and Heart Problems
Men going thin on top may be more likely to have heart problems than their friends with a full head of hair, according to researchers in Japan. Their study of nearly 37,000 people, published in the on-line journal BMJ Open, said balding men were 32% more likely to have coronary heart disease. However, the researchers said the risks were less than for smoking or obesity. A shifting hairline is a fact of life for many men. Half have thinning hair by their 50s and 80% have some hair loss by the age of 70. Researchers at the University of Tokyo sifted through years of previous research into links between hair loss and heart problems. They showed that hair that went thin on the crown was associated with coronary heart disease. This was after adjusting for other risk factors such as age and family history. However, a receding hairline did not seem to affect the risk. Dr. Tomohide Yamada of the University of Tokyo said, We found a significant, though modest, link between baldness, at least on the top of the head, and risk for coronary heart disease. We thought this is a link, but not as strong as many other known links such as smoking, obesity, cholesterol levels and blood pressure. He said younger men losing hair on the top of their head should focus on improving their lifestyle to ensure they keep their heart healthy. However, he said there was not enough evidence to suggest screening bald men for heart problems. Any explanation for the link is uncertain. There are ideas about increased sensitivity to male hormones, insulin resistance and inflammation in blood vessels affecting both the heart and the hair. The British Heart Foundation said that men should focus on their waistline, not their hairline.

Christians Attacked in Egypt
Three people, including a girl aged eight, died when gunmen on motorcycles opened fire on a wedding party outside a Coptic Christian church in Cairo. At least nine others were wounded in the attack in Giza, officials said. There was no immediate claim of responsibility.Egypt's Coptic Christian community has been targeted by some Islamists who accuse the Church of backing the army's overthrow of President Mohammed Morsi in July. The unidentified attackers fired indiscriminately as people left the church. A man and a girl were killed outside the church and a woman died on her way to hospital.
We heard a very loud sound as if something was collapsing, one eyewitness said.
I found a woman seated in a chair with lots of bullet wounds, covered in blood. Many other people had fallen around her, including a child, he added. Coptic priest Thomas Daoud Ibrahim said he was inside the church when the gunfire erupted.
What happened is an insult to Egypt, and it's not only directed against Coptic Christians. We are destroying our own country, he said. Another priest, Beshay Lotfi, told Egyptian media that the church had been left without a police guard since the end of June, 2013. The Coptic Orthodox Church is one of Christianity's oldest, founded in Alexandria around 50 AD and Christians make up about 10% of Egypt's population of 80 million.

Iceland’s UFO
A man shooting time lapse video of a town in Iceland captured an eerie, glowing light that flew into town. YouTube user Bjarki Mikkelsen went back to the tape he filmed in Northern Iceland's Akureyri on Sept. 29, and noticed the fireball, he says. At the 1:18 mark in his video, the red glowing light falls from the heavens and straight into town. There comes a strange glowing ball that I catch on web camera, Mikkelsen writes. I wonder about that. The rest of the internet began to wonder, too. The video has since been slowed down and scrutinized by paranormal organizations like UFO Disclosure Ireland, which speculates that there are "two beacon-type lights flashing" at the moment the object lands in town. Of course, there could be an easy explanation for the object. Drones and other unmanned aircraft are causing a rise in UFO sightings. The glowing light in Iceland isn't unlike a glowing light captured on a video in Brazil in early 2013.The Sao Paulo UFO turned out to be a drone, owned by a news agency.
