How the Net Neutrality Debate Affects Your Internet
The Federal Communications Commission (FCC) voted last week to start dismantling 2015 rules that regulated internet service providers the same way as utilities. The debate swirls around two related issues: whether the internet is a public utility, and how (or if) to ensure a concept known as net neutrality. Net neutrality is the framework for an internet in which all data is treated equally.

Ancient Egyptian Pharaoh Carving Found in Looting Hole
Egyptian authorities say they caught looters digging up an ancient stone block carved with an image of a pharaoh. In the city of Abydos, antiquities authorities say they were inspecting an old two-story, mud-brick house when they found that the owner had excavated a hole in the floor. The block was at the bottom of the hole, about 13 feet (4 meters) below the floor, according to an announcement from the Egyptian Ministry of Antiquities.

Just one glass of wine per day can raise your breast cancer risk
Cancer experts say they're increasingly confident that at least two lifestyle choices can affect a woman's risk of getting breast cancer: drinking alcohol and exercising. Just one alcoholic drink each day is enough to boost breast cancer risk, according to a comprehensive new report published Tuesday. Vigorous exercise, by contrast, can decrease the risk in both pre- and postmenopausal women. SEE ALSO: Alcohol's cancer risks outweigh any health benefits, study shows The American Institute for Cancer Research and the World Cancer Research Fund published their joint report, which includes data on 12 million women and 260,000 cases of breast cancer gathered in nearly 120 studies. Image: American Institute for Cancer Research"The evidence is clear: Having a physically active lifestyle, maintaining a healthy weight throughout life, and limiting alcohol — these are all steps women can take to lower their risk," said Anne McTiernan, a lead author of the report and a cancer prevention expert at the Fred Hutchinson Cancer Research Center in Seattle. The study gives researchers "even greater confidence in the results," McTiernan said in an email. Alcohol increases risks Tuesday's report upholds earlier findings about the links between alcohol consumption and breast cancer risk. Yet McTiernan said she was surprised to find that just one drink a day on average was enough to raise a woman's risk. In the U.S., a standard drink contains about 14 grams of pure alcohol, which is found in 5 ounces of wine, 1.5 ounces of distilled spirits, or 12 ounces of a 5-percent alcohol beer. The analysis of premenopausal women included 10 large cohort studies, in which more than 4,000 women developed breast cancer. While the increase in risk for drinking an average of 10 grams of alcohol per day was relatively small — about 5 percent — it is still statistically significant. Image: rob carr/Getty ImagesThe postmenopausal analysis included 22 large cohort studies, in which more than 35,000 women developed breast cancer. Researchers found a 9 percent increase in risk for drinking an average of 10 grams of alcohol per day, which is also statistically significant. There are still many unknowns about how and why alcohol consumption affects breast cancer risk, Melissa Pilewskie, a surgical breast oncologist at the Memorial Sloan Kettering Cancer Center, said in an interview. Pilewskie was not involved in Tuesday's report but said its findings were consistent with a number of other studies. She said it's unclear whether one drink per day is the same as having a few drinks here and there throughout the week. Alcohol consumption may also be a "surrogate" for other lifestyle factors that are the real risk culprits. Image: American institute for cancer researchWhatever the case, our drinking habits are one of the few areas of cancer risk that we can actually control, she said. Genetics, family history, age, breast density — these are much greater risk factors for breast cancer, but we can't change them. "For women who are at increased risk [of breast cancer], this is something we think likely could make a difference, even though it may be only a moderate difference," Pilewskie said. Exercise decreases risks The new report provided stronger evidence that moderate exercise can decrease the risk of post-menopausal breast cancer — the most common type of breast cancer. It also revealed, for the first time, that vigorous physical exercise can decrease the risk in premenopausal women as well. Premenopausal women who were the most active had a 17 percent lower risk of developing breast cancer, compared to those who were the least active, the report found. Postmenopausal women had a 10 percent reduction in risk. Alice Bender, a nutritionist at the American Institute for Cancer Research, said "vigorous" activity should be sufficiently intense that it's hard to carry on a sustained conversation. That could mean power walking, jogging, or cycling, depending on the person's fitness level. Bender acknowledged that exercising more and drinking less are not surefire ways to prevent cancer, just like exercising less and drinking more won't condemn you to a diagnosis. "There are no guarantees when it comes to cancer. We know a lot of things are out of our control," she said. But evidence increasingly suggests that healthier lifestyle choices can "move the needle" toward cancer prevention. Findings from Tuesday's breast cancer report will included in the cancer institutes' forthcoming 2017 report on diet, weight, physical activity and cancer prevention. A global panel of experts will also use the research to update the World Cancer Research Fund's Recommendations for Cancer Prevention.

Baby bump: China eatery in Japan soars on pregnant panda hopes
Swelling hopes for a baby panda in Tokyo have bumped up the stock price of a Chinese restaurant chain in the area, with locals setting their sights on a flurry of tourists. Eleven-year-old Shin Shin, who was brought to Ueno Zoo from China, has been showing signs of pregnancy since last week after mating with male Ri Ri in February, according to zoo officials. Giant pandas are notoriously clumsy at mating, with males said to be bad at determining when a female is in the right frame of mind and often befuddled at knowing what to do next.

Sherpas show how the human body can thrive in extreme environments
Mount Everest is a grueling, deadly place for many adventurers. Beyond the steep terrain, bone-chilling temperatures, and fierce weather, the air is so thin that your body can begin to shut down. That is, unless you're a Sherpa. Members of the Nepalese ethnic group have evolved over generations to withstand the oxygen-deprived atmosphere high in the Himalayas, a new study found. SEE ALSO: Now you can climb Mount Everest in VR Sherpas are, biologically speaking, extremely efficient at producing the energy they need to reach such heights, even where oxygen is scarce, according to research published Monday in the
Proceedings of the National Academy of Sciences. Their cells are akin to fuel-efficient cars that can travel farther on less fuel. A porter fetches the ladders to help fix the route for climbers attempting to reach the summit of Mount Everest.Image: Tashi Sherpa/AP/REX/ShutterstockScientists say the findings not only help explain Sherpas' mountain-climbing prowess — they may also lead to new ways of treating oxygen deficiencies, called "hypoxia," in hospital patients. "By understanding how Sherpas are able to survive with low levels of oxygen, we can get clues to help us identify those at greatest risk in [intensive care units] and inform the development of better treatments to help in their recovery," Michael Grocott, a co-author of the study and professor at the University of Southampton in England, said in a press release. Grocott is the chair of Xtreme Everest, a 10-year-old initiative by doctors, nurses, and scientists to study how our bodies respond to the extreme altitude on Mount Everest. Their ultimate goal is to improve outcomes for critically ill patients. With a 29,029-foot-high peak, Everest is the world's highest mountain. Everest Base Camp is around 17,600 feet, which is plenty high enough to sicken unadjusted visitors. An aerial photograph of Everest Base Camp.Image: Paula Bronstein/Getty ImagesAt those altitudes, where oxygen is scarce, the body is forced to work overtime to make sure the brain and body receive enough oxygen to function. Often, the body will produce more red blood cells, which carry blood to our organs and thicken the blood. As a result, blood flows more slowly and blood vessels are prone to tightening, which can cause dangerous build-up of fluid in the lungs and other risks. Mountain climbers can combat this by bringing oxygen supplies and ascending slowly, giving their bodies time to adjust. Sherpas, however, don't need such a boost. Previous studies have shown that Sherpas produce fewer red blood cells at higher altitudes. They also produce higher levels of nitric oxide, a chemical that opens blood vessels and keeps blood flowing, which in turn gives them more energy to climb. Sherpas' remarkable physical skills, along with their local expertise, have made them the go-to guides and porters for international expeditions. It's an imperfect arrangement, however. Nepalese guides in recent years have protested poor pay and unsafe working conditions, and in 2014, they went on strike after 16 colleagues were killed in an avalanche. People attend a prayer service in New York City for Sherpa victims of the April 18, 2014, avalanche on Mt. Everest.Image: eric thayer/Getty ImagesFor Monday's study, a research team led by scientists at the University of Cambridge followed 15 Sherpas and 10 "lowlanders" — researchers living in non-high altitude areas — as they gradually ascended to the base camp. The lowlanders took samples, including blood and muscle biopsies, at three different times: in London, for the baseline measurement; upon arrival to base camp; and after two months working at base camp. They compared those samples to those of the Sherpas, all of whom lived in relatively low-lying areas, and none of whom were "elite" high-altitude climbers. Sherpas' baseline measurements were taken in Kathmandu, Nepal. At baseline, Sherpas' mitochondria — the parts of human cells that respire to generate energy — were already more efficient at using oxygen to produce ATP than those of lowlanders, the samples revealed. ATP, or molecule adenosine triphosphate, is the energy that powers our bodies. A porter walks with a massive load towards Everest Base Camp near Lobuche, Nepal.Image: Tashi Sherpa/AP/REX/ShutterstockSherpas' measurements hardly changed once they reached the base camp, suggesting they were born with such biological traits. Lowlanders, meanwhile, saw their measurements change as their bodies acclimatized and began to mimic the Sherpas'. After two months at camp, Sherpas also produced more phosphocreatine, an energy reserve that acts as a buffer to help muscles contract when no ATP is available. Lowlanders, by contrast, saw their phosphocreatine levels crash. And, unlike lowlanders, Sherpas did not experience a rapid increase in free radicals, which are molecules created by a lack of oxygen that can potentially damage cells and tissues. "Sherpas have spent thousands of years living at high altitudes, so it should be unsurprising that they have adapted to become more efficient at using oxygen and generating energy," Andrew Murray, the study's senior author and a senior lecturer at the University of Cambridge, said in the press release. "When those of us from lower-lying countries spend time at high altitude, our bodies adapt to some extent to become more 'Sherpa-like', but we are no match for their efficiency," he said.

What is MILAMOS? Work begins on international rule book for future space warfare
An international committee is embarking on a three-year effort to establish globally-recognised ground rules for space warfare, in anticipation of a future in which battles are not only fought on Earth, but above it. A coalition of scientists, lawyers, academics and government representatives from around the world will come together to draft a document that will outline the legal parameters for military operations in space and its governance during war time. The Manual on International Law Applicable to Military Uses of Outer Space – or MILAMOS – seeks to determine the rules of engagement during space combat and whether current treaties regarding warfare could be applied to conflicts taking place miles above the Earth.

'Crypto' Parasite Top Culprit for Pool-Related Illnesses
If you got sick from swimming in a pool last summer, there's a good chance it was due to a tiny parasite called Cryptosporidium. The parasite, which causes cryptosporidiosis, or "crypto" for short, is the leading cause of recreational water-associated outbreaks, according to a new report from the Centers for Disease Control and Prevention. The number of cases of crypto in the U.S. have about tripled since 2004, according to the report, which was published today (May 18) as a part of the CDC's "Healthy and Safe Swimming Week." Crypto outbreaks are particularly associated with aquatic facilities that have one or more pools.
