• The uncertainty arises mainly because weather stations were never intended to provide a climatic record. The temperature series they give tend therefore to be patchy and even where the stations are relatively abundant, as in western Europe and America, they often contain inconsistencies.
• To most scientists, rising sea-levels, melting glaciers, warmer ocean depths and so forth are convincing.
• A new study, however, provides further evidence that the numbers are probably about right. » The full Economist article - Published: October 22, 2011.

• All cancers are caused by damage or mutations to the DNA of formerly healthy cells acquired during a person’s lifetime.
  This damage causes them to grow into abnormal lumps or tumors and spread around the body disrupting its normal processes and eventually – if unchecked – causing death.

• In lung cancer the damage is almost entirely caused by smoking and in skin cancer or malignant melanoma by ultra violent sunlight.
  The Sanger Institute studies used powerful new DNA sequencing technologies to decode completely the genome of both tumor tissue and normal tissue from a lung cancer and a malignant melanoma patient.
• They then compared and contrasted the two to discover the differences and see what damage has occurred to cause the disease. » The full Telegraph Uk article » By Richard Alleyne, Science Correspondent.

The scientific evidence supports the notion that humans evolved to be runners.

• In a 2007 paper in the journal Sports Medicine, Daniel E. Lieberman, a Harvard evolutionary biologist, and Dennis M. Bramble, a biologist at the University of Utah, wrote that several characteristics unique to humans suggested endurance running played an important role in our evolution.
• Most mammals can sprint faster than humans — having four legs gives them the advantage.
• But when it comes to long distances, humans can outrun almost any animal. Because we cool by sweating rather than panting, we can stay cool at speeds and distances that would overheat other animals. On a hot day, the two scientists wrote, a human could even outrun a horse in a 26.2-mile marathon. » The full New York Times article - By Tara Parker-Pope - Published: October 26, 2009.

Depending on the chemicals used, the skin cells became various kinds of cell that together make up healthy blood. They included early stage red blood cells, which carry oxygen around the body, white blood cells, which fight infection, and platelets that enable blood to clot.
The team, whose work is published in the journal Nature, is the first to show it is possible to convert human skin cells directly into blood. "We have shown this works

Meat Farmers Brace for Limits on Antibiotics
• Proponents of strong controls note that the European Union barred most nontreatment uses of antibiotics in
  2006 and that farmers there have adapted without major costs. Following a similar path
  in the United States, they argue, would have barely perceptible effects on consumer
  prices.

• As drug-resistant strains of microbes evolve on the farms, they are passed along in meat
  sold in grocery stores. They can infect people as they handle the uncooked product or
  when eating, if cooking is not thorough. The dangerous strains can also enter the
  environment via manure or the clothes of farm workers.
• Genetic studies of drug-resistant E. coli strains found on poultry and beef in grocery
  stores and strains in sick patients have found them to be virtually identical, and further
  evidence also indicated that the resistant microbes evolved on farms and were
  transferred to consumers, said Dr. James R. Johnson, an infectious-disease expert at the
  University of Minnesota. Hospitals now find that up to 30 percent of urinary infections
  do not respond to the front-line treatments, ciprofloxacin and the drug known as
  Bactrim or Septra, and that resistance to key newer antibiotics is also emerging. E. coli is
  also implicated in serious blood, brain and other infections. » Read the full New York Times Article - By Erik Eckholm - Published: September 15, 2010

... because of the possibility that both humans and chimps inherited an instinct for aggressive territoriality from their joint ancestor who lived some five million years ago. Only two previous cases of chimp warfare have been recorded, neither as clear-cut as the Ngogo case.
Dr. John Mitani’s team has now put a full picture together by following chimps on their patrols, witnessing 18 fatal attacks over 10 years and establishing that the warfare led to annexation of a neighbor’s territory. (Continued after the picture...)

The benefits of chimp warfare are clear enough, at least from the perspective of human observers. Through decades of careful work, primatologists have documented the links in a long causal chain, proving for instance that females with access to more fruit trees will bear children faster.
Dr. Mitani, however, is reluctant to infer any genetic link between human and chimp warfare, despite the similarity of purpose, cost and tactics. “It’s just not at all clear to me that these lethal raids are similar sorts of phenomena,” he said. More interesting than warfare, in his view, is the cooperative behavior that makes war possible. » The full New York Times article - By Nicholas Wade - Published: June 21, 2010

CT scans proved valuable Two studies published in the American Journal of Roentgenology show the need to check X-rays and CT scans for unusual features, and also point out swine flu can be tricky to diagnose in some of the sickest patients.
(in one study) CT scans of patients with severe cases of swine flu showed many had pulmonary emboli, which block the arteries in the lungs, a team at the University of Michigan found.
Anticoagulant drugs can break up these clots and save lives.
A team at the University of Michigan found..."The majority of patients undergoing chest X-rays with H1N1 have normal radiographs (X-rays)," Pulmonary emboli are also not normally seen in flu," Dr. Prachi Agarwalshe said in a statement.
"CT scans proved valuable in identifying those patients at risk of developing more serious complications as a possible result of the H1N1 virus, and for identifying a greater extent of disease than is appreciated on chest radiographs."

Scientists have been chasing earthquake prediction — the holy grail of earthquake science — for decades.

In the 1970s American seismologists declared that the goal was reachable. Yet we have little to no real progress to show for our efforts. We have a good understanding of the planet’s active earthquake zones. We’re pretty good at forecasting the long-term rates of earthquakes in different areas. But prediction per se, which involves specifying usefully narrow windows in time, location and magnitude, has eluded us.
The public would like scientists to predict earthquakes. We can’t do that. We might never be able to do that. What people and government can do is work to make sure our houses, schools and hospitals don’t fall down when the next big one strikes, and that we’re all prepared for the difficult aftermaths.

Dead zones occur when excess nutrients, primarily nitrogen and phosphorus, enter coastal waters and help fertilise blooms of algae, a process called eutrophication. Major nutrient sources include fertilisers and the burning of fossil fuels.

The result is an increase of nutrients in the water - usually nitrogen or phosphorus - that triggers a frenzy of action from microscopic organisms.

First phytoplankton take up the nutrients and produce organic matter than eventually sinks to the bottom and dies. There bacteria consume the organic matter and use up the oxygen as they do so. Article link - Telegraph.co.uk News.

The Institute of Medicine recently noted that you can meet your body’s need for liquids in many ways, including drinking coffee and tea (with or without caffeine) and eating fruits and vegetables with a high water content. Two clues that you may need to drink more are thirst and the color of your urine, which should be clear like, well, water.

If you are physically very active, especially in hot weather, repeatedly sipping cold water is helpful. But beyond two quarts, you may need to also replace the salts lost in sweat — for example, by drinking a diluted sports drink or eating foods with salt and potassium.

In an electronic device, like a computer or a radio, electrons stream in a steady flow through the machine's circuits, but the molecules in E. coli jostle and wander.
When E. coli begins using a gene to make a protein, it does not produce a smoothly increasing supply. It spurts out the proteins in fits and starts. One clone may produce half a dozen copies of a protein in an hour, while a clone right next to it produces none. Read Article » By Carl Zimmer - IHT

"The thing that's killing people is inaction," said Dr. Michael Sayre of Ohio State University, who headed the association's team that drafted the new recommendations.
Sayre said people not trained in CPR should do two things when they encounter an adult who has suddenly collapsed: first, call emergency services; and second, begin pushing "hard and fast" in the center of the person's chest.
This is necessary to maintain vital blood flow, according to experts. Chest compressions should continue until emergency medical services responders arrive, Sayre said. Read Article » By Will Dunham - Reuters

Lee was injured on July 2, 2006, during a geological field trip in the desert of California, when the car he was driving overturned. He emerged from a coma three days later, but his fourth cervical vertebra had been fractured.
Nevertheless, he was back to work in early 2007.
Every time he tested out a new device and adapted it for his own use, Lee said, he felt a little thrill, as if he had solved a scientific problem.
During lunch with colleagues recently, Lee amazed onlookers as he touched a headset microphone attached to his wheelchair with his right cheek to move the chair backward, and so prevent bedsores.
On his way back to his office from the cafeteria, Lee used his right cheek again to shift the wheelchair into cruise control mode. That mode buffers the shock when he uses his head to steer the wheelchair on a bumpy road.
"It's like downhill skiing," he said. - Read this NYT article » By Su-Hyun Lee

The problem was that the location of (63-year-old Brooke Zepp's) cancerous tumor was so deep that (surgeons) would not be able to get to it to remove it without damaging organs.
The organs, including her small intestine, liver, spleen, pancreas, as well as parts of her large intestine, were outside of her body for about an hour-and-a-half and were kept chilled.
Zepp is now recovering and is doing quite well, as the surgery was a success. Read Article »

The involuntary hospitalization of Britney Spears recently brought back memories.
Ten years ago, when I was 15, I was a high school dropout and heroin addict, living in the back of a dealer's van.
My mom first noticed red flags at 14: rapid weight loss, self-mutilation, coming home high, irregularly showering. The therapist she had me see, as well as my school counselor, believed that, cutting aside, my actions were typical teenage behavior.
The first time I ran away, though, my mother formed her own conclusions, and got a 5150 issued - California code for the involuntary 72-hour psychiatric hold that Spears was under, before she left the hospital last week.
I wish I had seen my first, forced hospitalization as the gift it was. Read Column » By Mia Fontaine - IHT

For decades, researchers believed that if people with diabetes lowered their blood sugar to normal levels, they would no longer be at high risk of dying from heart disease. But a major U.S. study of more than 10,000 middle-aged and older people with Type 2 diabetes has found that lowering blood sugar actually increased their risk of death, researchers reported.
The results do not mean blood sugar is meaningless. Lowered blood sugar can protect against kidney disease, blindness and amputation. But the findings inject an element of uncertainty into what has been dogma: that the lower the blood sugar the better, and that lowering blood-sugar levels to normal saves lives.

The Lindners share a defective copy of a gene known as BRCA1 (for breast cancer gene 1) that raises their risk of developing breast cancer sometime in their lives to between 60 percent and 90 percent.
Deborah Lindner began to seek support elsewhere, (and contacted) Bright Pink, a group of young women who have tested positive for the BRCA genes.
Lindsay Avner, its founder, lived in Chicago, and their meeting over coffee in the hospital lounge one evening in March lasted four hours. Avner, 24, had had a prophylactic mastectomy last year.
"You've got to see my breasts," she told Deborah Lindner, escorting her into the bathroom.
Avner's surgeon at Memorial Sloan-Kettering Cancer Center in Manhattan had used a technique that preserved the breast skin and nipples, leaving a scar only under the breast. Deborah, still in her scrubs, said, "Wow."
Deborah scheduled the double mastectomy with Dr. D.J. Winchester at Evanston Northwestern hospital for the last weekend in June, three days after her medical board exams.

The surgery and reconstruction took seven and a half hours, twice as long as the doctors had expected. The incisions were small, Winchester explained when he came out, and hidden under the breast, so it had taken a long time to scrape out all the breast tissue. - The full IHT article - By Amy Harmon.

"This is a really fundamental moment in the history of cancer research."

All cancers are caused by damage or mutations to the DNA of formerly healthy cells acquired during a person’s lifetime.
This damage causes them to grow into abnormal lumps or tumours and spread around the body disrupting its normal processes and eventually – if unchecked – causing death.
In lung cancer the damage is almost entirely caused by smoking and in skin cancer or malignant melanoma by ultra violent sunlight.
The Sanger Institute studies used powerful new DNA sequencing technologies to decode completely the genome of both tumour tissue and normal tissue from a lung cancer and a malignant melanoma patient.
They then compared and contrasted the two to discover the differences and see what damage has occurred to cause the disease. The full Telegraph Uk article » By Richard Alleyne, Science Correspondent.
