Q: Scientists said on Wednesday many Tibetans possess a rare variant of a gene involved in carrying oxygen in the blood that they likely inherited from an enigmatic group of extinct humans who interbred with our species tens of thousands of years ago. It enables Tibetans to function well in low oxygen levels at elevations upwards of 15,000 feet (4,500 meters) like the vast high plateau of southwestern China. People without this variant would be apt to develop thick blood, leading to high blood pressure, heart attacks, strokes, low-birth-weight babies and higher infant mortality. This version of the EPAS1 gene is nearly identical to one found in Denisovans, a lineage related to Neanderthals - but is very different from other people today. Denisovans are known from a single finger bone and two teeth found in a Siberian cave. DNA testing on the 41,000-year-old bone indicated Denisovans were distinct from our species and Neanderthals. “Our finding may suggest that the exchange of genes through mating with extinct species may be more important in human evolution than previously thought,” said Rasmus Nielsen, a computational biology professor at the University of California, Berkeley and the University of Copenhagen, whose study appears in the journal Nature. Our genome contains residual genetic fragments from other organisms like viruses as well as species like Neanderthals with which early modern humans interbred. The researchers called their study the first to show that a gene from an archaic human species has helped modern humans adjust to different living conditions. “Such exchange of genes with other species may in fact have helped humans adapt to new environments encountered as they spread out of Africa and into the rest of the world,” said  Nielsen. Asan Ciren, a researcher with China’s BGI genomics center, added, “The genetic relationship or blood relationship between modern humans and archaic hominins is a hot topic of the current paleoanthropology.”  The researchers said early modern humans trekking out of Africa interbred with Denisovans in Eurasia en route to China. Their descendants harbor a tiny percentage of Denisovan DNA. Genetic studies show nearly 90 percent of Tibetans have the high-altitude gene variant, along with a small percentage of Han Chinese, who share a common ancestor with Tibetans. It is seen in no other people. The researchers conducted genetic studies on 40 Tibetans and 40 Han Chinese and performed a statistical analysis showing that the gene variant almost certainly was inherited from the Denisovans. The gene regulates production of hemoglobin, a protein in red blood cells that carries oxygen. It is turned on when blood oxygen levels drop, stimulating more hemoglobin production. At elevations above 13,000 feet (4,000 meters), the common form of the gene boosts hemoglobin and red blood cell production, causing dangerous side effects. The Tibetans’ variant increases hemoglobin and red blood cell levels only modestly, sparing them these effects.

A: Gene from extinct human species fortifies high-altitude Tibetans.

Q: The advisory is for people using the waters for recreation. The advisory area is from the McAlpine Dam near Louisville to the Greenup Dam near Greenup in northeastern Kentucky. State officials also issued an advisory for Briggs Lake near Russellville. The advisory means algal toxins have been found at various locations along the water. Swimming, wading, and other water activities are not recommended during the advisory. State officials say ingested water may increase the risk of gastrointestinal symptoms such as stomach pain, nausea, vomiting and diarrhea. It can also cause skin irritation.

A: Kentucky issues harmful algae warning for Ohio River.

Q: "There was no discussion of the cost of fresh fruit and vegetables compared to the typical American diet of largely processed/fast foods. But it’s safe to assume most readers know the costs from their regular grocery shopping. The story provided information that the two groups did not differ in terms of rates for breast cancer recurrence, the main outcome of the study. The story only provided the information that the two groups did not differ in terms of rates for breast cancer recurrence, not survival. The story did mention that neither of the groups lost more weight, so such a high-fiber diet is not a guarantee for weight loss. The story does not mention any harms of a diet high in fiber and low in fat. Possible ""side effects"" of such a diet might include bloating, gas, and diarrhea or loose stools. The story discusses the study design and presents the absolute number of women who had a breast cancer recurrence in each group. The story does not mention that the study participants self-reported their dietary habits. The story did not engage in disease mongering. The story only quotes the author of an editorial on the newly published data. Her comment needs further explanation, so more information from her or from other researchers or clinicians not affliated with the study would have been useful, especially regarding a discussion of other benefits associated with a high-fiber low-fat diet focusd largely on plant-based foods. The story failed to mention other breast cancer recurrence strategies such as hormone and biological medications, etc. Other studies have suggested that weight management via diet and exercise may play a role in the prevention of certain types of breast cancer in post-menopausal women  (e.g hormone receptor negative). The story did mention prevention of excessive weight gain via diet and exercise would be the ""next frontier in cancer prevention research"". The story does not specifically mention the availability of a fresh fruits and vegetables for all populations, but the focus of the story is on the lack of evidence that a diet concentrated on these foods has any benefit for breast cancer recurrence. No preventative behavioral modification related to diet is advocated. The story was also suffienciently clear about what the ""treatment"" was (number of servings of vegetables and fruits, etc) such that if a person wanted to ""treat"" themselves in this manner they could replicate the intervention. The story mentions that this is a newly published study showing no evidence that a diet high in fruits and vegetables is not directly related to a decreased risk of breast cancer recurrence. Increasing fruits/vegetables in the diet is not a novel concept. The story does not appear to be taken directly from a press release and there is independent reporting."

A:
Intensive Vegetable-Fruit Diet Shows No Effect on Breast Cancer Return
