Missing links brewed in primordial puddles?

The crucibles that bore out early building blocks of life may have been, in many cases, modest puddles.

Now, researchers working with that hypothesis have achieved a significant advancement toward understanding an evolutionary mystery -- how components of RNA and DNA formed from chemicals present on early Earth before life existed.

In surprisingly simple laboratory reactions in water, under everyday conditions, they have produced what could be good candidates for missing links on the pathway to the code of life.

Role of animals in mitigating climate change varies across tropical forests

Large animals play a key role in mitigating climate change in tropical forests across the world by spreading the seeds of large trees that have a high capacity to store carbon, new research co-led by the University of Leeds has said.

The research, published in the journal Nature Communications, sheds important new light on the role seed dispersal by animals plays in mitigating climate change, and how this role can vary in tropical forests across the world.

Top tobacco control experts to FDA: Studies of e-cigs suggest more benefit than harm

WASHINGTON -- Seven top international tobacco control experts are prompting regulators at the U.S. Food and Drug Administration (FDA) to have a broad "open-minded" perspective when it comes to regulating vaporized nicotine products, especially e-cigarettes.

Writing in the journal Addiction, published online April 25, the researchers synthesize much of the evidence published to date on e-cigarettes, and suggest that use of these products can lead to reduced cigarette smoking overall with a potential reduction in deaths from cigarette smoking.

New study finds laundry detergent packets more dangerous than other types of detergent

(COLUMBUS, Ohio) - A new study conducted by the Center for Injury Research and Policy of the Research Institute at Nationwide Children's Hospital and the Central Ohio Poison Center found that exposure to laundry detergent packets is more dangerous to young children than exposure to other types of laundry and dishwasher detergent.

'Mediterranean' diet linked to lower risk of heart attacks & strokes in heart patients

A "Mediterranean" diet, high in fruit, vegetables, fish and unrefined foods, is linked to a lower risk of heart attack and stroke in people who already have heart disease, according to a study of over 15,000 people in 39 countries around the world. The research also showed that eating greater amounts of healthy food was more important for these people than avoiding unhealthy foods, such as refined grains, sweets, desserts, sugared drinks and deep-fried food - a "Western" diet.

The Lancet: Smoking cessation medications do not appear to increase risk of neuropsychiatric side effects, study finds

The smoking cessation medications varenicline and bupropion do not appear to increase the incidence of serious neuropsychiatric side effects compared to placebo, according to a study published in The Lancet today.

Smoking cessation drugs do not elevate risk of serious neuropsychiatric adverse effects

Compared to the nicotine patch and a placebo, the smoking cessation aids varenicline (marketed as Chantix in the U.S.) and bupropion (Zyban) do not show a significant increase in neuropsychiatric adverse events, reports an international team of researchers in a study published online April 22 in the journal The Lancet.

High alpine dairying may have begun over 3000 years ago

The discovery of dairy fats on ancient pottery may indicate dairying high in the Alps occurred as early as the Iron Age over 3000 years ago, according to a study published April 21, 2016 in the open-access journal PLOS ONE by Francesco Carrer from the University of York, UK, and colleagues.

Estrobolome disparities may lead to developing biomarkers that could mitigate cancer risk

Investigating disparities in the composition of the estrobolome, the gut bacterial genes capable of metabolizing estrogens in both healthy individualsand in women diagnosed with estrogen-driven breast cancer may lead to the development of microbiome-based biomarkers that could help mitigate the risk of certain cancers, according to a review paper published April 22 in the JNCI: Journal of the National Cancer Institute.

Scientists discover new reef system at mouth of Amazon River

Athens, Ga. - A new reef system has been found at the mouth of the Amazon River, the largest river by discharge of water in the world. As large rivers empty into the world's oceans in areas known as plumes, they typically create gaps in the reef distribution along the tropical shelves--something that makes finding a reef in the Amazon plume an unexpected discovery.

An international team--including scientists from the University of Georgia and the Federal University of Rio de Janeiro--documented their findings in an April 22 study published in the journal Science Advances.

Old-growth forests may provide buffer against rising temperatures

CORVALLIS, Ore. - The soaring canopy and dense understory of an old-growth forest could provide a buffer for plants and animals in a warming world, according to a study from Oregon State University published today in Science Advances.

Comparing temperature regimes under the canopy in old-growth and plantation forests in the Oregon Cascades, researchers found that the characteristics of old growth reduce maximum spring and summer air temperatures as much as 2.5 degrees Celsius (4.5 degrees Fahrenheit), compared to those recorded in younger second-growth forests.

Beyond milkweed: Monarchs face habitat, nectar threats

ITHACA, N.Y. - In the face of scientific dogma that faults the population decline of monarch butterflies on a lack of milkweed, herbicides and genetically modified crops, a new Cornell University study casts wider blame: sparse autumnal nectar sources, weather and habitat fragmentation.

First gene therapy successful against human aging

In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.

Danish investigators reduce sugar content of yogurt without reducing sweetness

Washington, DC - April 22, 2016 - A team from a Danish food ingredients company has manipulated the metabolic properties of yogurt-producing bacteria to sweeten the yogurt naturally, while reducing sugar in the final product. Similar manipulations have also all but eliminated lactose, so that those with lactose intolerance can enjoy the yogurt. They have accomplished all of this using microbiological methods that predate the era of genetic technologies.

Queen's researcher explores effectiveness of Extractive Industries Transparency Initiative

KINGSTON, ON - Queen's University political researcher Nathan Andrews has co-authored a report on the effectiveness of the Extractive Industries Transparency Initiative (EITI) in improving transparency and domestic government in resource rich countries suffering from the "resource curse."
