Boston, MA – When talking about genetic abnormalities at the DNA level that occur when chromosomes swap, delete or add parts, there is an evolving communication gap both in the science and medical worlds, leading to inconsistencies in clinical and research reports.

Johns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.

(SACRAMENTO, Calif.) — An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process. This is the first time the complex has been shown to perform both jobs. This newfound ability could make cyclin B1/Cdk1 an excellent target to control cellular energy production, potentially advancing cancer care and regenerative medicine. The research was published online today in the journal Developmental Cell.

RIVERSIDE, Calif. — One day about eight years ago, Katia Silvera, a postdoctoral scholar at the University of California, Riverside, and her father were on a field trip in a mountainous area in central Panama when they stumbled upon an orchid they had never seen before.

An international research team led by Cesar A. Arias, M.D., Ph.D., at The University of Texas Health Science Center at Houston (UTHealth) has identified a new superbug that caused a bloodstream infection in a Brazilian patient. The report appeared in the April 17 issue of The New England Journal of Medicine.

Massage therapy improves general blood flow and alleviates muscle soreness after exercise, according to a study by researchers at the University of Illinois at Chicago.

The study, reported online in advance of print in the Archives of Physical Medicine and Rehabilitation, also showed that massage improved vascular function in people who had not exercised, suggesting that massage has benefits for people regardless of their level of physical activity.

WASHINGTON, D.C. -- The world is less than 40 years away from a food shortage that will have serious implications for people and governments, according to a top scientist at the U.S. Agency for International Development.

"For the first time in human history, food production will be limited on a global scale by the availability of land, water and energy," said Dr. Fred Davies, senior science advisor for the agency's bureau of food security. "Food issues could become as politically destabilizing by 2050 as energy issues are today."

Spending time online has the potential to ward off depression among retirees, particularly among those who live alone, according to research published online in The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences.

WINSTON-SALEM, N.C. – April 17, 2014 – Meaningful long-term survival is possible for selected patients suffering from advanced cancer of the abdomen when treated with cytoreductive surgery with Hyperthermic IntraPeritoneal Chemotherapy, or HIPEC, according to a first-of-its-size analysis by physicians at Wake Forest Baptist Medical Center.

NEW YORK (17 April 2014)— Population Council scientists and their partners have found that their proprietary microbicide gel is safe, stable, and can prevent the transmission of multiple sexually transmitted infections (STIs) in both the vagina and rectum in animals: HIV, herpes simplex virus 2 (HSV-2), and human papillomavirus (HPV). The USAID-funded study also provides the first data that the gel is effective against multiple strains of HIV, and has a window of efficacy in the vagina against all three viruses of at least eight hours prior to exposure.

Several parasites and pathogens that devastate honeybees in Europe, Asia and the United States are spreading across East Africa, but do not appear to be impacting native honeybee populations at this time, according to an international team of researchers.

The invasive pests include including Nosema microsporidia and Varroa mites.

It's not uncommon these days to find a colored ribbon representing a disease. A pink ribbon is well known to signify breast cancer. But what color ribbon does one think of with lung cancer?

Although white has been identified as the designated color, for many suffering from the disease, black may be the only one they think fits.

TORONTO, April 17, 2014—While 94 per cent of Canadians surveyed said they would participate in public health programs that screen newborns for a specific number of genetic conditions, only 80 per cent said they would be willing to participate in screening that would sequence their newborns' genomes.Most newborns in North America have a "heel prick test" in their first day or two of life in which a tiny amount of blood is taken from their heels and tested for about five to 54 conditions, depending on the state or province.

TORONTO, April 17, 2014— Giving patients adrenaline after they suffer a cardiac arrest outside of a hospital does not increase their prospects of surviving long-term, according to new research conducted at St. Michael's Hospital.

A statistical analysis of the gift "fulfillments" at several hundred online wedding gift registries suggests that wedding guests are caught between a rock and a hard place when it comes to buying an appropriate gift for the happy couple. The details reported in the International Journal of Electronic Marketing and Retailing suggest that most people hope to garner social benefits of buying an expensive gift that somehow enhances their relationship with the newlyweds while at the same time they wish to limit monetary cost and save money.
