#Eating Poo Helps Packrats Digest Toxic Plantsdesert woodrats are picky but not in the way you might expect:
several woodrat populations in the U s. Southwest specifically eat a type of highly toxic creosote bush.
Another group eats juniper which is also toxic to many animals. This gives the woodrats (Neotoma lepida) a nice niche allowing them to dine on a plant that others avoid.
A new study suggests that the microbes in their gut break down the toxic chemicals in the plants
These animals apparently developed the ability to break down the plant compared to those just fed rabbit food who couldn't subsequently eat the toxic plant.
All this work with toxic plants poo and packrats has wider implications than you might imagine however.
It may be possible for example to help livestock feed on toxic plants like juniper which is spreading throughout the Southwest
since breeding in the lab can cause the animals to lose microbes necessary for digesting certain toxic plant compounds found in the wild.
But glyphosate is among the mildest herbicides available with a toxicity 25 times less than caffeine.
Its use has decreased reliance on more toxic alternatives such as atrazine. A 2012 paper from Iowa State university and the University of Minnesota suggested glyphosate-tolerant GMOS are responsible for monarchs'recent population decline.

The new research from the Universities of Leicester Sussex and Cambridge examines how locusts associate odours with nutritious or toxic food.
and they avoid eating toxic plants; but gregarious locusts eat these plants to'impregnate'themselves with toxins to deter predators.
Locusts should consider toxic food'bad 'while they live alone but'good'when they are in a swarm
When we presented solitary locusts with an unfamiliar odour together with toxic food they assigned it an aversive('bad')value.
and eat toxic plants to defend itself against predators. Then we asked if a solitary locust has learned already about an odour
so they will give the toxic plants another try. And because they can no longer form aversive memories any food is now rewarding
This is how they re-train themselves to eat the toxic plants. It would be great to be able to do this experiment in the field
And if you train solitary locusts with toxic food and vanilla they will also go to lemon.

Innate immune responses occur in subjects exposed to a foreign substance such as a pathogen or a toxic material like venom for the first time.
So the researchers believe the response could be generalized to different types of toxic venoms. Our findings support the hypothesis that this kind of venom-specific Ige-associated adaptive immune response developed at least in evolutionary terms to protect the host against potentially toxic amounts of venom such as would happen
if the animal encountered a whole nest of bees or in the event of a snakebite said Stephen Galli MD professor and chair of pathology and the co-senior author of the study.
whether Ige responses also protect humans from the toxic effects of arthropod or reptile venom but it would be unthinkable to test lethal doses of venom in humans.
and potentially toxic food that existed for much of our evolutionary history said Galli. And so we're left with this residual type of reactivity that seems completely mysterious and pointless and harmful.
This is the first evidence that we know of indicating that Ige-associated'allergic-type'immune responses can actually reduce the toxicity of naturally occurring venoms.

#Toxicity map of brain may help protect cognition for cancer patientsnew research from Wake Forest Baptist Medical center is giving radiation oncologists who treat brain tumors a better understanding of how to preserve the brain's functions while still killing cancer.
Radiation treatment of organs with cancer is designed to give enough of a dose to be toxic to the cancer tumor with minimal impact to the surrounding tissue
However the same isn't true for brain tissue so the researchers worked to develop a toxicity map of the brain to preserve function.
The issue is the toxicity to the brain and its function which is cognition or how you think
The toxicity map was created by taking advantage of data from larger clinical trials held at Wake Forest Baptist.
Participants completed cognitive testing upon enrollment and their scores provided the performance data for the toxicity map.
