Migraines Tied to Increased Risk of Heart Problems

Women who suffer from migraines are at higher risk of developing cardiovascular disease than women who aren’t plagued by the severe headaches, and they are more likely to have a stroke, heart attack or to die of heart disease, a new study reports.

The report, published in BMJ, is an analysis from the Nurses Health Study II, a Harvard study that tracked 115,541 women aged 25 to 42, from 1989 through June 2011. At the study’s start, 15 percent said they had migraines.

Brain-zapping devices have shocking potential, but are they safe?

The designers of Halo Sport, a headband they claim can improve athletic performance by shocking the brain, say their device could one day also help improve memory, foreign language acquisition, even math skills. The wearable device, initially tested and used as a training aid by elite athletes including former Olympic sprinter Michael Johnson and by the U.S. Ski and Snowboard Association, is now being offered to consumers. But a Canadian expert says those claims haven't been proven, and with no long-term studies on the health effects of transcranial direct-current stimulation (tDCS), selling such a device to consumers is "irresponsible."

4 Factors That Predict Startup Success, and One That Doesn’t

What makes a venture capital investment successful? Some of the most interesting data on this question comes from an analysis published last year by the venture capital firm First Round Capital. The firm's unique data set comprises information on over 300 companies and nearly 600 founders, including founder characteristics such as age, gender, education, firm location, and prior work and startup experience. The study found several correlates with success - some reassuring, some surprising.

First, it found that high-performing investments tend to have at least one female founder. This isn't surprising, given other research about the performance of diverse teams; it's a timely reminder of the importance of increasing female entrepreneurship and of the opportunity that VCs may be missing by continuing to disproportionately fund white men. The data also shows that younger founders and founders with prestigious educational backgrounds or prior experience in large technology companies tend to be more successful. There's evidence that startup success is somewhat geographically diverse, not limited to Silicon Valley. Good investments are increasingly coming from burgeoning technology centers in Texas and North Carolina.

Scientists use climate, population changes to predict diseases

British scientists say they have developed a model that can predict outbreaks of zoonotic diseases - those such as Ebola and Zika that jump from animals to humans - based on changes in climate.

Describing their model as "a major improvement in our understanding of the spread of diseases from animals to people", the researchers said it could help governments prepare for and respond to disease outbreaks, and to factor in their risk when making policies that might affect the environment.

How a smartphone could help spot disease

Many diseases leave biomarkers in the blood, but detecting them can be an involved and slow process.The markers may be present in small quantities and blood has to be collected and then delivered to a laboratory for analysis - a process which can take hours or days. But now a technique which makes uses of a smartphone could change this by providing results in minutes.

New Test Diagnoses Cancer Faster, Offers Patients Better Treatment

“Acute leukemia can kill a person in days and so a fast diagnosis is very important,” says Dr. Frank Kuo, a pathologist at Brigham and Women’s Hospital. Dr. Kuo and colleagues at the Brigham and the Dana Farber Institute developed a new test called a Rapid Heme Panel. “We can get a much better and accurate diagnosis and figure out the best treatment to that patient and avoid treatments that have a lot of side effects,” explains Dr. Neal Lindeman of the Rapid Heme Test. Dr. Lindeman is also a pathologist at the Brigham. “We can figure out if they’re responding quickly or not responding so we can make changes… It’s really a revolution from my perspective,” says Dr. Lindeman.The Rapid Heme Test has been used for the past nineteen months at the Brigham and at the Dana Farber in Boston and they’re running hundreds a month. It was the first test of its kind and is still the most comprehensive in the world.

It’s a paradox: Shouldn’t the most accomplished be well equipped to make choices that maximize life satisfaction?

Hot coffee conundrum

Posted by: Administrator in News |

http://www.cbc.ca/beta/news/thenational/hot-coffee-conundrum-1.3637926

Why it's worth the wait for hot beverages to cool. Earlier studies suggesting coffee is associated with bladder cancer were based on less reliable looks at the drink among heavy smokers. Larger, more recent studies in general populations followed over time to see how many cancers develop and how they might relate to coffee don't point to concern, Loomis said. What's more of a concern is the temperature of hot beverages. Population studies found the risk of esophageal cancer increased with beverage temperature in China, Iran, Turkey, and South America, where tea or maté — an infusion traditionally made from leaves of trees in South America — are consumed at about 70 C or 158F. Cancer of the esophagus, a muscular tube that connects the throat to the stomach, is the eighth most common cause of cancer worldwide and one of the main causes of cancer death.

The Future Of Water

The Colorado River has been a major source of water in the Southwestern United States region, but many worry that it's beginning to dry up. Some observers point to population growth, climate change and water mismanagement as causes in discussions regarding the dwindling river.Could the water crisis that has struck many Western states be a sign of what's to come for the rest of the nation? And who decides how much water is used or who controls it?

SFU professor demonstrates how water is created from thin air

Posted by: Administrator in Environment |

SFU professor Majid Bahrami has created a machine that turns air into water. “People are really struggling with water so water has become a major issue,” says Bahrami, who explains the prototype took three years to create after years of research. Unlike air conditioners, which can also similarly create condensation, he explains this prototype can create water under any weather conditions. The prototype works by enhancing the humidity in the air, and it can create between 19 to 40 liters a day.  He explains he built it with a goal in mind: to make drinking water more available to those who need it the most.
