A new Dutch invention makes it possible to reforest large desert and rocky areas in the coming years, they say. Experiments in the Sahara desert have shown that the WaterBoxx allows trees to grow under harsh conditions and can provide them with sufficient water.

The invention of the Dutch businessman and inventor Pieter Hoff has won the prestigious Beta Dragons Award during the annual Flying Dutchman 2008, Science Technology Summit in Amsterdam. A board of scientists and captains of industry proclaimed his design to be the most promising and innovative project.

Researchers at the University of Utah are enrolling people in a new clinical trial that uses a patient's own stem cells to treat ischemic and non-ischemic heart failure.   The one-year Cardiac Repair Cell Treatment of Patients with Dilated Cardiomyopathy (IMPACT-DCM) study will look at the safety of injecting Cardiac Repair Cells (CRC) and their ability to improve heart function.

The temperature might not be the only thing plummeting this winter. Many people also will experience a decrease in their vitamin D levels, which can play a role in heart disease, according to a new review article in Circulation. 

Vitamin D deficiency results in part from reduced exposure to sunlight, which is common during cold weather months when days are shorter and more time is spent indoors. 

"Chronic vitamin D deficiency may be a culprit in heart disease, high blood pressure and metabolic syndrome," said Sue Penckofer, PhD, RN, study author and professor, Marcella Niehoff School of Nursing, Loyola University Chicago. 

A study published today in the online advance edition of The American Journal of Psychiatry for the first time reveals shape differences in the brains of children with ADHD, which could help pinpoint the specific neural circuits involved in the disorder.

Did you go to basic training for the military?  If so, it is a special memory and you remember it vividly but you don't want to repeat it.   On the opposite end of the spectrum, the truly special positive experiences are not something we want to repeat either - we want to keep them as memories.

So most people are unlikely to return to the place of their Honeymoon because they can't repeat it and don't want to diminish the memory.
 
A new study in the Journal of Consumer Research says people tend to treat their memories of previous special experiences as assets to be protected.

According to the Centers for Disease Control and Prevention, more people die from lung cancer than any other cancer type. In fact, according to 2004 data, more people died from lung cancer than breast, prostate and colon cancers combined. 

Smoking is the biggest risk factor for developing lung cancer, even after quitting for long periods of time.   But only 10% of smokers get lung cancer and almost 50% of lung cancer cases involve former smokers.
