Our research identified three key lessons.
A night of revelry can mean an uncomfortable day after.
Researchers know the basic biology of what happens to your system after a night of heavy drinking. Unfortunately, evidence-based cures for the common hangover are still at the investigation stage.

Increased use of renewable energies could help curb climate change, but the water required for their production has dispossessed rural Guatemalans.
A medium-size passenger jet burns roughly 750 gallons of fuel per hour.
Scientists have engineered sugarcane to increase its oil content and are developing renewable jet aircraft fuel from the oil. The engineered sugarcane could become a valuable energy crop.
Algae could be the key to a new type of biofuel.
The right kind of algae can be converted to biofuel, and there are potential side benefits for carbon capture.
The great dream of cars running on sustainable petrol has not bitten the dust. Here's why.
Mine’s a Star-opramen.
It's like one great big distillery up there.
Soybeans and corn are two of the most widely planted crops in the United States and the main feedstocks used to make biofuels.
A new study challenges the longstanding view that biofuels are carbon-neutral, and asserts that in the U.S. to date, they have done more harm to the climate than gasoline.
Ethanol made from corn goes into our gas tanks. Now refiners who pay for the subsidy are complaining of rising costs.
A fight's breaking out over who should pay subsidies for corn ethanol, and it is consumers who may end up paying for any changes.
Before there was E10, in the 1970s there was ‘gasohol,’ another name for gasoline that had been blended with ethanol.
Ted Cruz opposes subsidies for biofuels and still managed to win in ethanol-friendly Iowa. Is corn ethanol starting to lose its political clout?
The ultimate problem: intensive corn production.

A law signed into effect last week seeks to reduce fertilizer runoff that causes toxic algae blooms. But to really address the problem requires taking a hard look at how America farms.
