Could fungal collection hold the key to new life-saving drugs?

...d to new medicinal products. Previous work at SIDR found activities from plant extracts against diabetes, obesity and psoriasis. Professor Alan Harvey, Director of SIDR said: “We are delighted to be working with CABI and to have access to their fantastic source of fungal samples. We hope that this no...

New findings challenge established views on human genome

...rved as species evolve. However, the ENCODE effort found about half of functional elements in the human genome do not appear to have been obviously constrained during evolution, at least when examined by current methods used by computational biologists. According to ENCODE researchers, this lack of evo...

Plants recognize their siblings, biologists discover

Penn researchers link cell's protein recycling systems

...luenced the severity of neurodegeneration. “We found that whenever we knocked the lysosome system down, neurodegeneration always got worse,” says Taylor. “Then when we activated the autophagy system by feeding the flies a drug called rapamycin, neurodegeneration was prevented.” The accumulated misfolde...

Plastic that grows on trees

... the most effective method yet to convert glucose, found in plants worldwide and nature’s most abundant sugar, to HFM, a chemical that can be broken into components for products now made from petroleum. It has been an elusive goal for the legion of chemists trying to pull it off: Replace crude oil as the ...

454 sequencing identifies HIV drug resistance at early stage

...nt variants detected by Ultra Deep sequencing were found to be extremely important as it enabled the prediction of early antiretroviral treatment failure with strong statistical significance. “Current genotypic resistance technology available to clinicians is limited to detecting resistance mutations that...

Exploring the dark matter of the genome

Research finds that circadian rhythms dominate all life functions

...es a domino effect. However, very few genes are found to be oscillating in the same phases in different tissues or organs. In fact, only about 5 percent of all genes fall into the same phase or timing of peaks and valleys. Synchronization with the activity of the other genes and genes in different organ...
