Scientists make new discovery about bird evolution
A team of scientists has described the most exceptionally preserved fossil bird discovered to date, in a newly published article. The new specimen from the rich Early Cretaceous Jehol Biota (approximately 131 to 120 million years old) is referred to as Eoconfuciusornis, the oldest and most primitive member of the Confuciusornithiformes, a group of early birds characterized by the first occurrence of an avian beak.

An increasing proportion of women who are 60 years of age and older are drinking
Most older Americans drink alcohol. Given that this segment of the population is projected to almost double by 2050, reaching 112 million, in the future, there will likely be many more older drinkers in the United States than currently. Importantly, older individuals are more sensitive to alcohol’s effects than their younger counterparts, and are also more likely to take prescription medications that can interact negatively with alcohol, potentially leading to falls and other injuries. This study examined trends in drinking status among U.S. adults 60 years of age and older.

New gene discovered associated with Tau, a common form of brain pathology
Investigators have reported the discovery of a new gene that is associated with susceptibility to a common form of brain pathology called Tau that accumulates in several different conditions, including Alzheimer's disease, certain forms of dementia and Parkinsonian syndromes as well as chronic traumatic encephalopathy that occurs with repeated head injuries.

Biodiversity loss shifts flowering phenology at same magnitude as global warming
Researchers have revealed that declining plant diversity -- from habitat loss, human use, and other environmental pressures -- causes plants to flower earlier, and that the effects of diversity loss on the timing of flowering are similar in magnitude to the effects of global warming. The finding could have a powerful influence on the way scientists study ecosystem changes and measure the effects of global warming.

Moderate drinking linked to lower risk of some -- but not all -- heart conditions
Moderate drinking is associated with a lower risk of several, but not all, cardiovascular diseases, finds a large study of UK adults. The finding that moderate drinking is not universally associated with a lower risk of all cardiovascular conditions suggests a more nuanced approach to the role of alcohol in prevention of cardiovascular disease is necessary.

Amazingly fast, cheap genome sequencing: Zika virus mosquito genome assembled from scratch
A team of scientists has developed a new way to sequence genomes, which can assemble the genome of an organism, entirely from scratch, dramatically cheaper and faster.

In a sample of blood, researchers probe for cancer clues
One day, patients may be able to monitor their body's response to cancer therapy just by having their blood drawn. A new study has taken an important step in that direction by measuring a panel of cancer proteins in rare, individual tumor cells that float in the blood.

Seven months after Rio Olympics, Zika continues to plague babies in urban slums
The near-paranoia related to Zika leading up to the 2016 Rio Games could have been avoided by heeding the lessons of previous epidemics, argues a new study.
