ITHACA, N.Y. The survival of the fittest might just be the survival of the steadfast instead. Having a positive attitude could be evolutionarily advantageous, according to Cornell researchers who simulated generations of evolution in a computational model.
Researchers have found an evolutionary connection between dinosaurs and dung beetles. An international team of scientists uncovered the first molecular evidence indicating that dung beetles evolved in association with dinosaurs. The findings place the origin of dung beetles (Scarabaeidae: Scarabaeinae) in the Lower Cretaceous period, with the first major diversification occurring in the middle of the Cretaceous. This timeline places their origins approximately 30 million years earlier than previously thought. The research explores the potential of a co-extinction with dinosaurs 66 million years ago. The study was published today in the open-access journal PLOS ONE.

Children infected even just once with a certain type of waterborne parasite are nearly three times as likely to suffer from moderate or severe stunted growth by the age of two than those who are not – regardless of whether their infection made them feel sick, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
Current estimates of the number of cheetahs in the wild are 'guesswork', say the authors of a new study which finds that the population in the cheetah stronghold of Maasai Mara, Kenya, is lower than previously thought.

Centuries before modern countries such as Dubai and China started building islands, native peoples in southwest Florida known as the Calusa were piling shells into massive heaps to construct their own water-bound towns.
Visitors to national parks are half as likely to see wolves in their natural habitat when wolf hunting is permitted just outside park boundaries, according to a new study.
Road crashes are the world’s leading cause of preventable death and injury in people under 35, accounting for around 5 million casualties every year. Repeat offenders make a disproportionate contribution to these statistics – and are known for their poor response to education and prevention efforts. But a better understanding of the subconscious and emotional processes of high-risk drivers could make a difference, according to new research from McGill University.
Whilst countries in the tropics and subtropics exhibit diverse patterns of seasonal flu activity, they can be grouped into eight geographical zones to optimise vaccine formulation and delivery timing, according to a study published April 27, 2016 in the open-access journal PLOS ONE by Siddhivinayak Hirve from the World Health Organization, Geneva, Switzerland, and colleagues.
Researchers at McMaster University have found that a single minute of very intense exercise produces health benefits similar to longer, traditional endurance training. The findings put to rest the common excuse for not getting in shape: there is not enough time.
In a study published in March in the journal PLOS One, University of Iowa computer scientists used two years of Twitter data to measure users' life satisfaction, a component of happiness.
The Zika virus was present in Haiti several months before the first Zika cases were identified in Brazil, according to new research by infectious-disease specialists at the University of Florida.
Scientists have discovered Sarmientosaurus musacchioi, a new species of titanosaurian dinosaur, based on an complete skull and partial neck fossil unearthed in Patagonia, Argentina, according to a study published April 26, 2016 in the open-access journal PLOS ONE by Rubén Martínez from the Laboratorio de Paleovertebrados of the Universidad Nacional de la Patagonia San Juan Bosco (UNPSJB), Argentina, and colleagues.

Multiple dispersals of penguins reached Australia after the continent split from Antarctica, including 'giant penguins' that may have lived there after they went extinct elsewhere, according to a study published April 26, 2016 in the open-access journal PLOS ONE by Travis Park from Monash University, Australia, and colleagues.

While norovirus is often linked in the news to outbreaks on cruise ships, the highly contagious stomach bug sickens nearly 700 million around the world every year and results in roughly $4.2 billion in health care costs and $60.3 billion in societal costs annually, new Johns Hopkins Bloomberg School of Public Health research suggests.
Long-term use of the cholesterol-lowering drugs known as statins does not appear to decrease a patient’s risk of colorectal cancer, suggests a new, large case-control study from Penn Medicine researchers published this week in PLOS Medicine.
As the threat of the Zika virus rips through the Americas and news headlines, another more deadly tropical disease is also on the move: Leishmaniasis is a parasitic infection that currently endangers an estimated 350 million people around the world. By combining two decades of research, ancient tribal medicine and the latest in gene editing technology – a team of scientists is creating what could be the first ever live-attenuated vaccine to prevent Leishmaniasis both here and abroad.

New research based on high-resolution x-ray movies reveals that despite having extremely underdeveloped muscles and wings, young birds acquire a mature flight stroke early in their development, initially relying heavily on their legs and wings to work in tandem to power the strenuous movement. The new study, published today in the journal PLOS ONE, is important for understanding the development of flight in modern birds and reconstructing its origins in extinct dinosaurs.

Much of the world may cringe as lemurs are hunted and killed or when entire forests are burnt and harvested for charcoal. However, if local residents don't perceive the actions as crimes or they believe there's a low risk of getting caught, then poaching and deforestation will continue.

Researchers at the University of Wisconsin–Madison School of Veterinary Medicine (SVM) have developed one of the first mouse models for the study of Zika virus. The model will allow researchers to better understand how the virus causes disease and aid in the development of antiviral compounds and vaccines.
CLEMSON — Rapid expansion of cities around the world has raised concerns about deteriorating quality of life in urban areas. Lincoln Larson, assistant professor in the Clemson University parks, recreation and tourism management department, said people often struggle to find ways to preserve health and happiness amidst sometimes harsh, stress-inducing urban environments. However, it appears that one path to long-term happiness may lead straight through the closest park.
