First Diploid Human Genome Sequence Shows We're Surprisingly Different

This new genome represents the first time a true diploid genome from one individual -- Dr. J. Craig Venter, has been published. From the combined data of more than 20 billion base pairs of DNA, the team was able to assemble the majority of Dr. Venter's genome. Since this genome assembly uniquely catalogues the contributions of each of the parental chromosomes, for the first time the amount of...

Pop Stars More Than Twice As Likely To Die An Early Death

Rock and pop stars are more than twice as likely as the rest of the population to die an early death, and within a few years of becoming famous, reveals new research. The findings are based on more than 1050 North American and European musicians and singers who shot to fame between 1956 and 1999.

Knee Arthritis Linked To Lung Cancer

Arthritis of the knee may be the first sign of a type of lung cancer that is hard to treat in heavy smokers, suggests new research. The researchers reviewed the case notes of all patients with rheumatic disorders, diagnosed at one tertiary referral centre over six years.

Onset Of Diabetes Higher In Patients Who Have Had Heart Attacks

People who have had heart attacks are at higher risk of developing both new-onset diabetes and the pre-diabetes condition impaired fasting glucose (IFG), conclude authors of a recent article. Patients with a recent heart attack were up to four-and-a-half times more likely to develop diabetes (3.7%) compared with the general population (0.8-1.6%), and more than 15 times more likely to develop IFG...

Population Movements And Money Remittances Spur Forest Regrowth

A study of social and economic influences on forest recovery in El Salvador highlights the importance of population movements spurred by war, land-use reforms and remittances of money by emigrants. Most analyses of forest cover in Central America have focused on loss of old-growth forests. In drawing attention to regrowth of woodland in a country that was extensively deforested during the 1970s,...

Work Time Is Largest Influence To Duration Of Person's Sleep

Work time is the primary lifestyle factor with the largest reciprocal relationship to a person's sleep time --- the more hours a person works, the less sleep that he or she gets, according to a new study. Short sleepers also spent more time engaged in education, household activities and, for very short sleepers, watching TV. Except for time spent watching TV, which increased with longer sleep...

'One Of The Most Curious Objects In The Sky' Delights Astronomers Again

Edwin Hubble once called IC 10 "one of the most curious objects in the sky," and new observations of the extremely faint, lightweight dwarf galaxy are giving scientists new clues about how populations of stars are born. Though the properties of stars is one of the most well-studied topics in astronomy, scientists still don't fully understand all the mechanisms involved in star formation and...

Burden Of COPD Is Higher Than Thought And Will Increase As World Population Ages

Higher levels and more advanced stages of chronic obstructive pulmonary disease (COPD) occur worldwide than previously thought. This burden will increase as the world's population continues to age, conclude authors of an article in The Lancet. The authors add that the growing COPD burden is partly due to the aging population (with risk nearly doubling for every 10 years over the age of 40), and...

'Skinny Gene' Exists

Researchers have found that a single gene might control whether or not individuals tend to pile on fat, a discovery that may point to new ways to fight obesity and diabetes. It was discovered that the gene, which is also present in humans, is likely to be a high-level master switch that tells the body whether to accumulate or burn fat.

America May Learn From Quebec's Prescription Drug Plan

A new study finds a number of similarities between Canadian drug coverage and that of the United States, despite their publicized differences. Looking at Quebec's Prescription Drug Insurance Program and the United States' Medicare Prescription Drug, Improvement and Modernization Act (MMA), the study suggests that the older Canadian plan may provide valuable insights for American decision-makers.

Anti-obesity Gene Keeps Mice And Worms Lean

Researchers have revealed an anti-obesity gene that has apparently been keeping critters lean during times of plenty since ancient times. The gene, first discovered by another team in flies, also keeps worms and mice trim, according to the new report. If the gene works similarly in humans, the findings could lead to a new weapon against our burgeoning waistlines, according to the researchers.

Avocados May Help Prevent Oral Cancer, Study Shows

Nutrients taken from avocados are able to thwart oral cancer cells, killing some and preventing pre-cancerous cells from developing into actual cancers, according to researchers. They found that extracts from Hass avocados kill or stop the growth of pre-cancerous cells that lead to oral cancer. Hass avocados are year-round fruits known for their distinctive bumpy skin that turns from green to...

Blending DNA and Nanotechnology

A team of researchers propose the marriage of DNA self-assembly with standard microfabrication and lithography tools to form features such as nanochannels, nanowires and nanoscale trenches. This discovery may open up new avenues for nanofabrication at dimensions not accessible by conventional optical lithography.

Blood Pressure Drugs Cut Death Rate In Type 2 Diabetes

The largest-ever study of treatments for type 2 diabetes has shown that a combination of two blood pressure lowering drugs reduced the risk of death, as well as the risks of heart and kidney disease. The scientists reported that the treatment reduced the likelihood of dying from the complications of diabetes by almost one-fifth.

Burning Extra Calories With A 'Futile Protein Cycle'

A new study points to a new method for burning off all those irresistible extra calories -- by turning on an energy-draining, but otherwise futile, cycle of protein synthesis and breakdown. The researchers found that the animals that ate the most food also expended the most energy. "That would be ideal for people who are overweight," the scientists said. "They could continue to eat and just waste...

Cancer Can Be Detected By Scanning Surface Veins

Researchers have developed technology to detect tumor cells within the human body. By shining a laser on surface veins, such as those on the wrist and inside the cheek, researchers are able to reveal and count circulating tumor cells. The new detection method is able to evaluate a much larger volume of blood than what can be drawn from a patient for analysis, said one of the scientists.

Color Night Vision In The Aye-Aye, A Most Unusual Primate

A quest to gain a more complete picture of color vision evolution has led scientists to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. They have performed the first sweeping, genetic evolutionary study of color vision in the aye-aye (pronounced "eye-eye"), a bushy-tailed, Madagascar native primate with a unique combination of physical features...

First Beehives In Ancient Near East Discovered

Archaeologists revealed that the first apiary (beehive colony) dating from the Biblical period has been found in excavations in Israel's Beth Shean Valley. This is the earliest apiary to be revealed to date in an archaeological excavation anywhere in the ancient Near East, according to the researcher.
