Mitochondrial DNA mutations and maternal age

A study explores the mother-to-child transmission of genetic variants linked with diseases such as cancer and diabetes. The cell’s metabolic powerhouse, the mitochondrion, harbors its own maternally inherited genome that can sometimes contain multiple mitochondrial DNA (mtDNA) types in one individual, a phenomenon known as heteroplasmy.

Reconstructing pesticide use from lake sediments

By analyzing sediment cores, researchers have partially reconstructed the dynamics of pesticide mobility from vineyard soil into a downstream lake in eastern France, suggesting that soil erosion tied to the use of pesticides and to other viticultural practices may have carried residues of long-banned insecticides into the lake.

The specific receptor targeted by naltrexone to enhance diabetic wound closure is OGFr

Naltrexone, an opioid antagonist, blocks OGFr that functions as part of a regulatory pathway related to cell replication. Topical naltrexone stimulates cell replication in full thickness cutaneous wounds in a receptor mediated manner. Using primary rat fibroblast cell cultures, the specific and selective receptor pathway blocked by naltrexone was determined to be OGFr, not classical opioid receptors. Animal studies confirmed that only naltrexone, and not other opioid receptor antagonists, enhanced full thickness cutaneous wounds.

Drug-infused nanoparticle is right for sore eyes

For the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have developed a topical solution containing nanoparticles that will combat dry eye syndrome with only one application a week.

Mothers who decide to breastfeed their children beyond 1 year of age consider their child's physical and social development to be most important, while the advice of health care professionals, family and friends are least important, according to a study to be presented Monday, Oct. 13 at the American Academy of Pediatrics (AAP) National Conference & Exhibition in San Diego.

Star-forming galaxy a window into the distant past?

Researchers have identified a starburst galaxy, or one that is churning out stars at an exceptionally high rate, that has many of the traits that would have been necessary to provide the first bit of starlight to the dark, early universe following the Big Bang.

Fewer kids and more elderly -- not the end of the world

Amidst warnings that low fertility rates will strain government funds and lower the standard of living in many developed nations around the world, Ronald Lee and colleagues suggest that moderately low fertility rates and slowly-declining populations may actually improve standards of living.

Prosthetic hands & arms that 'belong'

In the field of neuroprosthetics, scientists are getting closer to mimicking the intuitive control, freedom of movement, and sense of touch that people with natural limbs often take for granted. Dustin Tyler and colleagues provide the first long-term evidence that the under-the-skin wires and nerve electrodes for a neuroprosthetic hand can last after being subjected to real-world use by two adult male amputees.

HIV’s shape-shifting envelope protein

A new imaging technique has revealed how the protein HIV uses to infect cells changes shape, and the results may offer new ways to attack the deadly virus with drugs and vaccines. The HIV-1 envelope protein, Env, can shift its shape to take on several different configurations, something it needs to do before the viral and host cell membranes can fuse.

Wildlife Refuge Plans Show Strengths and Weaknesses for Adaptation to Climate Change

Despite a plenitude of general advice for land managers facing climate change, few studies have examined what might be practical for conservation reserves. The US Fish and Wildlife Service’s comprehensive conservation plans for national wildlife refuges show that it is possible to incorporate many ideas into practice. But wider use of emerging decision-support tools and regional-level coordination could help managers better prepare for coming landscape-scale changes.

Public priorities in ocean protection

Public concern regarding anthropogenic ocean health impacts such as pollution, overfishing, and acidification is likely related to awareness about impacts, according to a study. Many efforts to achieve sustainable use of oceans rely on expert opinion to set priorities and policy, often without assessing public priorities and awareness of ocean issues.

Genetically influenced traits and educational achievement

According to a study, differences in children’s level of educational achievement are associated with a large group of inherited traits. Educational achievement is generally considered to be the result of environmental influences such as classroom environment and parental involvement, but recent research suggests that differences in educational achievement may be heritable.

“Virological Penicillin”:Plant MIR2911 directly targets influenza A viruses

In a new study, Chen-Yu Zhang’s group at Nanjing University present an extremely novel finding that a plant microRNA, MIR2911, which is enriched in honeysuckle, directly targets influenza A viruses (IAV) including H1N1, H5N1 and H7N9. Drinking of honeysuckle soup can prevent IAV infection and reduce H5N1-induced mice death.

Experts recommend against diagnosing testosterone deficiency in women

The Endocrine Society today issued a Clinical Practice Guideline (CPG) advising against the use of testosterone therapy in healthy women.Androgens are a group of sex hormones that includes testosterone. DHEA is a prohormone that can be converted into testosterone or estradiol, a form of estrogen. While these are often thought of as male hormones, small amounts of androgens also are found in women.

Satellite Data Reveal Wealth of Hidden Tectonic Structures

Using the latest data from satellites in space, scientists have uncovered uncharted features in the seafloor, 80% of which remains unmapped. The rifts, ridges and trenches of the ocean floor are shaped by the slipping and sliding of massive tectonic plates. In many parts of the ocean, however, including the region of the Indian Ocean where the Malaysian aircraft was lost this year, scientists don't know much about seafloor tectonics.

Cheetahs and Pumas Strike a Balance to Hunt

Being a carnivore -- stalking, chasing and killing your prey -- is hard work. But two new studies show that cheetahs and pumas have their hunts down to a science. The studies suggest that mid-size predators, or mesopredators, may not be as energetically constrained by resources and competition as researchers had imagined. However, they also imply that human activity could offset the delicate balance these mesopredators have struck over thousands of years of evolution.
