A mechanism tries to stop our T cells from causing autoimmune disorders, and it's like a tight handshake that kills overly aggressive T cells.

When Boy Fish Build Castles to Impress Girl Fish, Boy Genes Get a Rise

A special breed of cichlid fish has allowed researchers to match up gene activation with behavior. The up and down-regulation of genes may actually be steering ritual mating behaviors. The research is potentially useful in understanding autism since some genes involved in the fish behavior have human genetic cousins implicated in autism spectrum disorder.

Instinctive behavior may be directly driven be gene regulation, at least researchers were able to match the two up.

Swapping Bacteria May Help ‘Nemo’ Fish Cohabitate with Fish-Killing Anemones

A clownfish peers out of an anemone in a tank at Georgia Aquarium. Anemones usually sting, kill and eat fish, but not clownfish. Georgia Tech researchers found that the microbial colonies in the slime covering clownfish shifted markedly when the nested in an anemone. Could the microbes be putting out chemical messengers that pacify the fish killer? Credit: Georgia Tech / Ben Brumfield

Why the fish-killing anemone spares the clownfish is a scientific mystery that Georgia Tech marine microbiologists are now tackling in fish mucus.

Flu Vaccine Supply Gaps Can Intensify Flu Seasons, Make Pandemics Deadlier

Urine Test Detects Organ Transplant Rejection, Could Replace Needle Biopsies

A T cell, here in purple, makes contact with a transplant organ cell, here in reddish brown. The T cell secretes the enzyme granzyme B, here in gray, which attacks the organ cell. But granzyme B also severs fluorescent signal molecules, in green, from the rejection detecting nanoparticle, in light pink. The signal molecules make their way into the urine, where they give off a fluorescent cue. Georgia Tech / EllaMaru Studio (work for hire, all rights GT, free for distribution).

Urine Test to Evaluate Immunotherapy Success Gets $1.8 Million NIH Research Grant

The activity sensor illustrated in reddish-pink with small, green attachments is shown here in its application to detect organ transplant rejection. T cells secrete the enzyme granzyme, here in gray, which kills cells but also severs the fluorescent green signal molecules from the activity sensing nanoparticle. The green signal molecules make their way into the urine, where they give off a fluorescent cue. Credit: Georgia Tech / EllaMaru Studios work for hire / press handout

Immunotherapy can eradicate cancer or fall down trying, and this sensor monitors that success or failure.
