	Herpes virus rearranges telomeres to improve viral replication A team of scientists, led by researchers at The Wistar Institute, has found that an infection with herpes simplex virus 1 (HSV-1) causes rearrangements in telomeres, small stretches of DNA that serve as protective ends to chromosomes. The findings, which will be published in the Dec. 24 edition of the journal Cell Reports, show that this manipulation of telomeres may explain how viruses like herpes are able to successfully replicate while also revealing more about the protective role that telomeres play against other viruses.
Roller coaster rides trigger pediatric stroke Riding a couple roller coasters at an amusement park appears to have triggered an unusual stroke in a 4-year-old boy, according to a report in the journal Pediatric Neurology.
	Team discovers reasons for malaria's drug resistance Scientists from Nanyang Technological University (NTU) have discovered exactly how the malaria parasite is developing resistance towards the most important front-line drugs used to treat the disease.

Human exposure to metal cadmium may accelerate cellular aging A new study led by a researcher at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University looks at the metal cadmium and finds that higher human exposure can lead to significantly shorter telomeres, bits of DNA at the ends of chromosomes that are associated with cardiovascular disease, diabetes and other diseases of old age. The study, which was published online today in the American Journal of Epidemiology, is the largest-ever to look at cadmium exposure and telomeres.
Early identification of modifiable risk factors for cognitive decline Signs of cognitive decline related to aging populations, and even the severe cognitive losses seen in Alzheimer's disease and neurodegenerative disorders, may emerge many years earlier, according to a report presented today at the American College of Neuropsychopharmacology annual meeting in Phoenix (Arizona). The study suggests that early signs of cognitive decline are already present for some individuals during midlife, and that they are linked with risk factors such as elevated blood pressure. It is possible that if these risk factors are identified and modified early on, it will be possible to help detect and prevent the progression of cognitive deficits later in life.

Three San Antonio studies target androgen in breast cancer Three studies presented by University of Colorado Cancer Center researchers at the San Antonio Breast Cancer Symposium 2014 demonstrate the effects of blocking androgen receptors in breast cancer. One shows that, counterintuitively, blocking the action of androgen receptors reduces the growth of estrogen-positive (ER+) breast cancers. The second study found that even triple-negative breast cancers (TNBCs), which are without known hormone drivers and carry the poorest prognosis, are dependent on androgen receptor activation. And the third study finds that targeting androgen receptors along with known cancer drivers HER2 or mTOR has a synergistic effect in which more cancer cells are killed by the combination than the sum of the cells killed by both drugs, combined.
Early adoption of robotic surgery leads to organ preservation for kidney cancer patients Patients with operable kidney cancers were more likely to have a partial nephrectomy—the recommended treatment for localized tumors—when treated in hospitals that were early adopters of robotic surgery, according to a new study.

	Senescent cells play an essential role in wound healing Senescent cells have a bad-guy reputation when it comes to aging. While cellular senescence - a process whereby cells permanently lose the ability to divide when they are stressed - suppresses cancer by halting the growth of premalignant cells, it is also suspected of driving the aging process. Senescent cells, which accumulate over time, release a continual cascade of inflammatory cytokines, chemokines, growth factors and proteases. It is a process that sets up the surrounding tissue for a host of maladies including arthritis, atherosclerosis and late life cancer.

	Middle East respiratory syndrome coronavirus unlikely to reach epidemic status, research says Middle East respiratory syndrome coronavirus (MERS-CoV) is an emerging virus, with the first case reported in 2012. It exhibits a 40% fatality rate and over 97% of the cases have occurred in the Middle East. In three new studies in the current issue of the International Journal of Infectious Disease, researchers reported on clinical outcomes in the Kingdom of Saudi Arabia (KSA), how long patients will shed virus during their infections, and how the Sultanate of Oman is dealing with cases that have appeared there. An editorial in the same issue discusses how the relatively high percentage of infections has been hospital-acquired, which reduces the possibility that MERS-CoV will reach pandemic or even epidemic status.
Youngest bone marrow transplant patients at higher risk of cognitive decline Toddlers who undergo total body irradiation in preparation for bone marrow transplantation are at higher risk for a decline in IQ and may be candidates for stepped up interventions to preserve intellectual functioning, St. Jude Children's Research Hospital investigators reported.
