The world's oceans contain algae that produce certain chemicals
that can accumulate in seafood and are known to cause brain damage.

This natural neurotoxin, domoic acid, is a very stable and heat resistant and is also toxic to the kidneys, but at much lower concentrations than guidance has suggested, according to an upcoming study in the Journal of the American Society of Nephrology (JASN).

It's cold and snowy just about everywhere except where you expect it. Ice in northern Alaska’s lakes during winter months is on the decline, as shown by twenty years of satellite radar imagery demonstrating how changes in our climate are affecting high-latitude environments - at least in the last few decades. 

Changes in air temperature and winter precipitation over the last five decades have affected the timing, duration and thickness of the ice cover on lakes in the Arctic. In this region, warmer climate conditions result in thinner ice cover on shallow lakes and, consequently, a smaller fraction of lakes freezing all the way through during winter months. 

We have a biological clock related to sleep cycles and a new paper says we have weight loss cycles related to behavior; people are going to gain weight on the weekend so if they lose more during the week, that weight loss cycle will result in better health.

Dr. Brian Wansink of the marketing department at Cornell University, in collaboration with researchers from the VTT Technical Research Centre of Finland and Tampere University of Technology, looked into the impact that the seven-days-a-week human cycle has on weight.

For the past eight years, the Amazon rain forest has gotten greener as the weather seemingly got hotter and drier each year from June to October. 

Limited rainfall didn't prevent thriving vegetation, which really put a damper on the simplistic 'turn one climate knob and all of our issues are solved' narrative. 

Why do men and women have different heights? Why do people have different predispositions to BMI, blood pressure and lipid levels?

Chromosome X is one of the two sex-determining chromosomes and researchers from the University of Helsinki set out to analyze the commonly occurring genetic variation in chromosome X  to find genetic factors that could explain individual differences in various traits.

Hundreds of genetic variants having an effect on these traits have already been identified but the X chromosome has not been studied in most of  previous studies. 25,000 Northern European individuals later, the researchers say they have some answers. 

How are accurate are the world's most advanced weather forecasting models?

They perform okay, at least when it comes to predicting the very near future.  Two University of Iowa researchers, David Lavers and Gabriele Villarini, evaluated rainfall forecasts from eight different global numerical weather prediction (NWP) models and their ability to predict the Sept. 9th-16th, 2013 extreme rainfall that caused severe flooding in Boulder, Colorado.

During September of 2013, Boulder County and surrounding areas experienced severe flooding and heavy rain resulting in fatalities, the loss of homes and businesses, and the declaration of a major disaster.
