Process to detoxify edible parts of a plant

German researchers have found a new method to stop unwanted toxins from entering the edible parts of the plant, which they claim will make it more suitable for animal feed.

The new technology called 'transport engineering' developed by researchers from the University of Copenhagen and can prevent unwanted toxins that plants produce to defend themselves against potential enemies, from herbivorous pests to diseases, from entering the its edible parts.

"We have developed an entirely new technology that we call 'transport engineering'. It can be used to eliminate unwanted substances from the edible parts of crops," head of the Center of Excellence for Dynamic Molecular Interactions (DynaMo) at the University of Copenhagen, Professor Barbara Ann Halkier said.

Oilseed rape plants produce 'glucosinolates' to protect themselves.

Farmers can only use limited quantities of the protein-rich rapeseed for pig and chicken feed due its presence which is harmful to most animals when consumed in large amounts.

"We managed to find two proteins that transport glucosinolates into the seeds of the thale cress plant, a close relative of the oilseed rape. When we subsequently produced thale cress without these two proteins, the remarkable result was that their seeds were completely free of glucosinolates and thus suitable for feed," Halkier said in a press release.

Proteins that can reverse acute liver failure

Scientists claim to have found that the recently discovered protein could reverse acute liver failure in humans, following its success in experiments done on mice.In a new study by German researchers, the liver failure was reversed and the mice recovered completely and they hope to soon be able to test this approach in clinical trials with patients.

The researchers utilised the recently discovered protein ARC (apoptosis repressor with caspase recruitment domain), which serves as the body's own survival switch. ARC is present in heart, skeletal muscle and the brain, but not in the liver.In cancer cases, apoptosis is deactivated in the tumour cells allowing the cancer cells to grow.
Researchers are looking for ways to reactivate apoptosis to drive the proliferating cancer cells to die out.However, in acute liver failure the problem is not too little but rather too much apoptosis.

The researchers have fused ARC to a noninfectious fragment of the human immunodeficiency virus(HIV), called TAT for short.The researchers used TAT as a shuttle to transfer this survival-switch construct into the liver."ARC is very fast acting, and this is a huge advantage, because in an emergency there is not much time for treatment

Brain wired differently with 'autobiographical' memory

Scientists have found why some people can remember minute details of their life while others can’t.

Only 33 people are known to have the condition hyperthymesia where they can perfectly recall everything since about the age of 10.

Researcher Aurora LePort and colleagues identified differences in their brain structure and found they have more robust white matter linking the middle and front parts of the brain than those with a normal memory, the Daily Express reported.

Most of the differences in the brain were in areas associated with autobiographical memory.

The research also found that such people are not better at remembering facts and figures in tests

The study has been published in the journal of Neurobiology of Learning and Memory.
