Maybe it’s time fish use sunblock. A new study has found the first skin cancers in wild fish, specifically in coral, bar-cheeked, and blue spotted trout swimming on Australia’s Great Barrier Reef. The lesions and dark patches are a scalier version of what melanomas look like on humans, but it’s unclear whether they make the animals unsafe to eat.
Scientists know how to give fish skin cancer in the lab. They [...]
An artificial “brain” built by a 17-year-old whiz kid from Florida is able to accurately assess tissue samples for signs of breast cancer, providing more confidence to a minimally invasive procedure.
The cloud-based neural network took top prize in this year’sGoogle Science Fair.
“I taught the computer how to diagnose breast cancer,” Brittany Wenger, the Lakewood Ranch resident, told me today.
“And this is really important because currently the least invasive form of biopsy [...]
From Washington’s Blog:
… Low levels of radioactive cesium from Japan’s Fukushima Daiichi nuclear accident turned up in fish caught off California in 2011, researchers reported Monday.
The bluefin spawn off Japan, and many migrate across the Pacific Ocean. Tissue samples taken from 15 bluefin caught in August, five months after the meltdowns at Fukushima Daiichi, all contained reactor byproducts cesium-134 and cesium-137 at levels that produced radiation about 3% higher than natural [...]
We noted more than a year ago:
The ocean currents head from Japan to the West Coast of the U.S.
Of course, fish don’t necessarily stay still, either. For example, the Telegraph notes that scientists tagged a bluefin tuna and found that it crossed between Japan and the West Coast three times in 600 days:
That might be extreme, but the point is that fish exposed to radiation somewhere out in the ocean might end up in [...]
ANCHORAGE, Alaska (AP) — Alaska polar bears are losing their fur and U.S. Geological Survey scientists don’t know why.
In the past two weeks, nine of 33 bears checked by scientists in the southern Beaufort Sea region near Barrow were found to have alopecia — loss of fur — and skin lesions, said Tony DeGange, chief of the biology office at the USGS Science Center in Anchorage.
Three of four bears inspected Thursday [...]
