Behind the Police Tape at a Forensic Science Program

This doll lists all of the symptoms of abrin, the toxin of the rosary pea (Abrus precatorius) seed. The red and black beans are often made into jewelry like the doll’s necklace. Photo by Nicholas Gerbis/KJZZ.

Every great investigator tells a story about the one that got away.

For Kimberly Kobojek, director of the forensic science program at Arizona State University’s West campus, formerly of the Phoenix Police Crime Lab, that white whale was a reddish brown stain.

Study Zeroes in on the Genetics of Sunburn

Ouch. Photo by Phil Kates.

With summer fast approaching, many turn their thoughts to swimsuit bods and summer tans. Now, a new genetic study might help explain why some of us burn while others tan.

The answer could help predict who gets skin cancer, because severe sunburns, particularly in childhood, strongly intensify skin cancer risk.

A team of researchers has applied a powerful genetic tool to the fight against the spotted wing fruit fly (Drosophila suzukii).

The destructive, invasive pest deposits its eggs inside of ripening fruit.

Citrus Roots Reach Back to the Himalayas

Citrus originated at the foot of the Himalayas. Artist’s conception by Manuel Talon, Instituto Valenciano de Investigaciones Agrarias (IVIA), Spain.

They say when life gives you lemons, make lemonade. But what if life hands you sour oranges and citrons?

Simple: You make lemons.

So says a new genetic analysis by an international team of scientists that seeks to clear up citrus’ tangled backstory.
