Predation Linked To Evolution, Study Suggests
Vitamin D Supplements Appear To Be Associated With Lower Risk Of Death
The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters. For decades, there has been a debate between paleontologists, biologists, and ecologists on the role of ecological interactions, such as predation, in the long term patterns of animal evolution.
Salmon spawn baby trout in experiment
Individuals who take vitamin D supplements appear to have a lower risk of death from any cause over an average follow-up time of six years, according to a meta-analysis of 18 previously published studies. Individuals who took vitamin D had a 7 percent lower risk of death than those who did not.
$25 Million in Prizes Is Offered for Trip to Moon
AP - Papa salmon plus mama salmon equals ... baby trout? Japanese researchers put a new spin on surrogate parenting as they engineered one fish species to produce another, in a quest to preserve endangered fish.
Study Sees Cities' Air Quality Worsening
The contest calls for entrants to land a rover on the moon that will be able to travel at least 550 yards and send high-resolution video, still images and other data back home.
Are You Sure That Is Who You Think It Is?
A study released Thursday predicts more bad air days in the summer for Cleveland, Columbus and eight other eastern U.S. cities if global warming continues unabated.
Counselling Conquers Constipation
A new technique which enables us to identify faces more accurately could make security systems more reliable. Humans are very good at identifying faces we know. However, researchers said, we are much less accomplished when the face is unknown to us. This is almost always the case with the faces captured by CCTV cameras or used to check at a passport barrier.
Erectile Dysfunction Treatment For Men With Spinal Cord Injuries
Psychological factors can make people more likely to suffer physical illness, but cognitive behavioural therapy can help sufferers manage their condition. "People often pigeonhole diseases as being biological or psychological, but in fact they're often a complex mixture of both," according to a researcher. She and her colleagues studied 1000 people who contracted either glandular fever or food poisoning. They wanted to see who would go on to develop irritable bowel syndrome.
Hispanics' Hypertension Better Controlled With Equal Access To Care
The drug tadalafil appears to improve erectile function in men with spinal cord injuries, according to a new article. Between 10.4 and 83 individuals per million worldwide experience spinal cord injuries every year, according to background information in the article. Only 25 percent of men with spinal cord injuries are able to have erections that are adequate for having intercourse.
To Maximize Biofuel Potential, Researchers Look For Sorghum's 'Sweet Spot'
With equal access to medical care and medication, Hispanic men and women have as good or greater chance as non-Hispanics of controlling their high blood pressure, researchers reported in Hypertension: Journal of the American Heart Association.
Toward A Vaccine Against Tropical Disease Caused By A Parasitic Worm
While sweet sorghum and sugarcane are close relatives, the researchers have shown that the two species have different ways of moving and storing sugar. Tracer sucrose is inserted into growing plants, using a system similar to an IV. Once the sucrose is inside the plants, the researchers can track the movement and distribution.
Trout lend sperm to sterile salmon
Researchers provide new details about the inner workings of a parasitic worm that causes a tropical disease called schistosomiasis, which leads to itchy skin, fever, chills, muscle aches, and liver disease that, in some cases, can be fatal. The new results may help design drugs or vaccines against the disease. Schistosomiasis, a disease affecting up to 200 million people in Asia, Africa, and South America, is spread by parasitic worms called blood flukes that live in fresh water. The worms enter the human body through the skin and move to either the large intestine, small intestine, or the bladder.
'Missing Dwarf Galaxy' Problem May Be Solved
AFP - Japanese scientists helped infertile salmon sire baby trout by lending them trout sperm, a technique that could save endangered species, according to research published in the United States Thursday.
Condoms Are Not 'One Size Fits All'
Scientists may have solved a discrepancy between the number of extremely small, faint galaxies predicted to exist near the Milky Way and the number actually observed. In an attempt to resolve the "Missing Dwarf Galaxy" problem, two astronomers used the W. M. Keck Observatory in Hawaii to study a population of the darkest, most lightweight galaxies known, each containing 99% dark matter. The findings suggest the "Missing Dwarf Galaxy" problem is not as severe as previously thought, and may have been solved completely.
Getting Motivated For Fitness
Health professionals are regularly confronted by men's complaints that condoms do not fit, or that they are uncomfortable. Correct condom use is critical for preventing unwanted pregnancies and the spread of sexually transmissible infections, yet a new study found that study participants who reported problems with the fit and feel of condoms were also among those who reported the highest rates of condoms breaking and slipping.
Sex After Cancer
A fitness expert encourages her personal training clients to break their more ambiguous goals of say, feeling better or dropping a few dress sizes, into smaller goals that can be achieved in three to four weeks. She discourages weight-oriented goals because weight loss is a long-term process and everyone loses weight at different rates. Instead, she wants to know how her clients feel. She is a big fan of small steps and a forgiving temperament. If a goal is not met, she said, it should be reassessed to make sure it's reasonable and then sought after again -- after a brief break.
Japan launches first lunar probe
Significant sexual problems often are an unexpected -- and unwelcome -- side effect of the treatment of early-stage cervical and endometrial cancer for many women following hysterectomy. A targeted therapeutic approach involving mindfulness training has been found to improve desire, orgasm, arousal and other aspects of sexual satisfaction in just three one-hour sessions.
New System Helps Aircraft Avoid Turbulence
Japan's space agency launches its first lunar orbiter for a year-long mission to explore the Moon.
Novel Mechanism That Balances Sizes Of Brain's Functional Areas Identified
A new turbulence detection system, now being tested, is successfully alerting pilots to patches of rough air as they fly through clouds. The system is designed to better protect passengers from injuries caused by turbulence while reducing flight delays and lowering aviation costs.
Signaling Protein For Multiple Myeloma Identified
In the cerebral cortex, the brain's powerful central processing unit responsible for higher functions, specialized subdivisions known as areas are laid out like a map, but little is known about the genetic forces that shape the geography of our brains.
Study sees cities' air quality worsening
Researchers have discovered a mechanism that plays a critical role in the multiple myeloma cell cycle and survival. This new research may result in identification of a new therapeutic target for treating multiple myeloma.
Kaguya Spacecraft Rockets Towards the Moon
AP - A study released Thursday predicts more bad air days in the summer for Cleveland, Columbus and eight other eastern U.S. cities if global warming continues unabated.

3-D Fruit Fly Images To Benefit Brain Research
AP - A fired utility company welder accused of sabotaging dozens of natural gas pipelines, at one point causing a blowout and requiring evacuations, was sentenced Thursday to five years in prison.
Scientists have used an imaging technique called optical projection tomography (OPT) to image individual cavities within the brain of an aging fly and see the brain deteriorate. The OPT images could help to speed up genetic research into Alzheimer's and other human diseases affecting brain cells.
