WARSAW, Poland (AP) – “Polish prosecutors have opened an
investigation into how a train ended up on the wrong tracks after two engines
collided head on late Saturday, killing 15 people and leaving 54 in
hospitals.

Prime Minister Donald Tusk called the accident the most
tragic train catastrophe in Poland in recent years…..”

“……[S]ome scientists are already comparing Friday’s storms to the super outbreak of April 1974, when tornadoes killed more than 300 people and injured more than 5,000 over a period of two days. …”

“…..The spate of storms was the second in little more than 48 hours, after an earlier round killed 13 people in the Midwest and South. They were the latest in a string of severe-weather episodes that have ravaged the heartland in the past year.

Friday’s violent storms touched down in at least a dozen states, killing 19 people in Kentucky, 14 in Indiana, three in Ohio, and one each in Alabama and Georgia.

The National Weather Service said the four twisters to hit Kentucky were the worst in the region in 24 years. In Indiana, an EF-4 tornado — the second-highest on the Fujita scale that measures tornadic force — packing 175 mph winds hit the town of Henryville, and stayed on the ground for more than 50 miles. Three tornadoes in Kentucky had wind speeds up to 160 mph……..”

“…….. Sharks are known to bioaccumulate toxins that may pose health risks to consumers of shark products. The feeding habits of sharks are varied……. The cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) has been detected in species of free-living marine cyanobacteria and may bioaccumulate in the marine food web. In this study, we sampled fin clips from seven different species of sharks in South Florida to survey the occurrence of BMAA…….. BMAA was detected in the fins of all species examined with concentrations ranging from 144 to 1836 ng/mg wet weight. Since BMAA has been linked to neurodegenerative diseases, these results may have important relevance to human health. We suggest that consumption of shark fins may increase the risk for human exposure to the cyanobacterial neurotoxin BMAA.”
