Forty million years after dinosaurs went extinct, one of the largest predators that ever prowled Earth’s oceans emerged, feeding the imaginations of modern scientists and the nightmares of modern movie audiences.

Megalodon — the name means ‘giant tooth’ — appeared some 23 million years ago and reigned the seas for about 21 million years. In 400 million years of shark evolution, megalodon is the most massive shark species that ever lived, growing to 60 feet long, or three times the size of the largest of today’s great whites.

Bioengineering Professor Changqing Li was recently awarded a four-year, $2.5 million R01 grant from the National Institutes of Health (NIH) to help develop a focused X-ray luminescence tomography (FXLT) scanner that could accelerate cancer research.

The scanner is a first-of-its kind molecular imaging tool that will allow researchers to visualize how disease progresses and monitor the effectiveness of novel drug-delivery systems in live animals — without invasive surgeries or euthanizing the animals.

Every 10 minutes, someone is added to the national organ transplant waiting list, and about once every hour, someone on the list is removed — either because they died while waiting or grew too ill for surgery.

The number of Americans on the waiting list totals more than 114,000 as of this writing, and about 30,000 transplants will be performed this year. In part, that’s because there are not enough organ donors.
