Bisphenol A, known as BPA, is in the middle of an environmental culture war and a hurriedly-rushed replacement, Bisphenol S (BPS), is just as big a concern.
We need plastic, food items are covered in plastic to make them last longer and protect them from microbes, but we know that plastic bottles and films take between 100 and 400 years to degrade, so the quest for alternative materials to plastics has been ongoing. That means we should not rush to embrace things just because they are 'not BPA', which still has no evidence of harm (unless hyperactive zebrafish count).
A new research project has identified a specific gene in soybean that has great potential for soybean crop improvement because it can be bred to better tolerate soil salinity - that means less changes to soil and the ecosystem while still getting more food.
The researchers from the University of Adelaide in Australia and the Institute of Crop Sciences in the Chinese Academy of Agricultural Sciences in Beijing pinpointed a candidate salt tolerance gene after examining the genetic sequence of several hundred soybean varieties.
A recent study showed that a virtual reality cognitive training game could be a screening tool for patients with mild cognitive impairment (MCI) among a sample of older adults. Mild cognitive impairment is a condition that often predates Alzheimer's disease and is characterized by memory loss and inability to execute complex activities such as financial planning.

Today my colleagues and I had the great privilege to announce a remarkable new discovery: a dolphin-like reptile that prowled the Middle Jurassic waters 170 million years ago.-->
A large international analysis of 174,000 patients has shown conclusively that statin treatment reduces the risk of cardiovascular disease in women.
Many cancer survivors face physical and mental challenges, such as sexual dysfunction or anxiety about getting cancer again or financial hardships, even decades after the treatment is ended.
Finding ways to help will become increasingly important because more cancer patients are living many years after treatment. The number of U.S. survivors is expected to top 19 million by 2024. While most survivors do well after treatment, some experience continuing problems that can significantly impair their quality of life well beyond the 5-year survival milestone. The problems and challenges can vary by the type of cancer patients had and the treatments they received.

Recent results of a study finds that that sensor changes have significantly biased temperature observations from the Snowpack Telemetry (SNOTEL) station network.
More than 700 SNOTEL sites monitor temperature and snowpack across the mountainous western U.S. SNOTEL provides critical data for water supply forecasts. Researchers often use SNOTEL data to study mountain climate trends and impacts to mountain hydrology and ecology.
University of Montana and Montana Climate Office researcher Jared Oyler and colleagues applied statistical techniques to account for biases introduced when equipment was switched at SNOTEL sites in the mid-1990s to mid-2000s.
The massive ice sheet that covers about 80 percent of Greenland is the largest single chunk of melting snow and ice in the world
and for that reason it is considered the biggest potential contributor to rising sea levels due to glacial meltwater in a warming world.
What gets the most media, and therefore a lot of research, attention is the ice sheet's aquamarine lakes -- bodies of meltwater that tend to abruptly drain -- and monster chunks of ice that slide into the ocean to become icebergs.
