This is, quite possibly, the biggest science journalism fail in the history of ever.
IN THE HISTORY OF EVER.
OKAY, when we discover new drugs and antivirals and such, we usually dont build these pharmaceuticals from scratch. We steal them from evolution, and try to make them *better* for *our* purposes in the lab– modify them, concentrate them, purify them, until we have a new drug.
You dont go suck on a tree if you have a headache– you pop a couple aspirin.
You dont get a prescription for moldy bread when you have a sinus infection– you pop a couple antibiotics.
We are always looking for new stuff to steal for new purposes– I can give you a couple examples from HIV World:
Green Tea: There is a compound in green tea that we might be able to modify, concentrate, and purify into a putative antimicrobicide gel to combat HIV-1 infection. You will not ever get a therapeutic effect from regular green tea.
Bananas: *insertobviousjokehere* Heh, ‘insert’… anyway, same story. There is a compound in bananas that scientists might be able to modify, concentrate, and purify into a new pharmaceutical. You are not going to get any kind of positive benefit from bananas, eating them or *ahem* otherwise.
So some scientists did the same thing we have been doing for ages– looking for a maybe-new-drug in nature:
Protective effect of structurally diverse grape procyanidin fractions against UV-induced cell damage and death.
UV radiation leads to the generation of reactive oxygen species (ROS). These molecules exert a variety of harmful effects by altering key cellular functions and may result in cell death. Several studies have demonstrated that human skin can be protected against UV radiation by using plant-derived antioxidants. Here we evaluated the in vitro capacity of several antioxidant polyphenolic fractions from grape, which differ in their degree of polymerization and percentage of galloylation, to protect HaCaT human keratinocytes against UV-induced oxidative damage. These fractions inhibited both basal and UVB- or UVA-induced intracellular ROS generation in this cell line. Consequently, the same fractions inhibited p38 and JNK1/2 activation induced by UVB or UVA radiation. The highest protective effect was for fractions rich in procyanidin oligomers and gallate esters. These encouraging in vitro results support further research and should be taken into consideration into the clinical pharmacology of plant-derived polyphenolic extracts as novel agents for skin photoprotection.
If you add some goop from different purified parts of grapes to cells in culture in the lab, the cells did okay when exposed to UVA or UVB. Maybe, one day in the future, a pharmaceutical company will isolate/modify/purify/concentrate a component of grapes, and it will be in like, sunscreen or something, and called ‘polyhexasaxamaphone’ and you wont even know that sunscreen component was derived from grapes, unless the company uses it as a marketing gimmick.
This is how the media interpreted this paper:
