Some Flowers Create Blue Halo to say Hello to Foraging Bees

Some flowers have found a nifty way to get the blues.

They create a blue halo, apparently to attract the bees they need for pollination, scientists reported Wednesday. Bees are drawn to the color blue, but it's hard for flowers to make that color in their petals.

US Researchers Genetically Modify Corn to Boost Nutritional Value

U.S. researchers said this week they have discovered a way to genetically engineer corn, the world's largest commodity crop, to produce a type of amino acid found in meat.

The result is a nutritionally rich food that could benefit millions worldwide, while also reducing the cost of animal feed. The breakthrough came in a report in the National Academy of Sciences, a peer-reviewed journal. 

Researchers say the process involves infusing corn with a certain type of bacteria in order to produce methionine, an amino acid generally found in meat.

Ocean Conference Raises Over $7 Billion for Marine Protection

A global conference organized by the European Union aimed at better protecting marine life has raised more than $7 billion.

During the Our Ocean conference that concluded Friday in the Maltese capital of Valletta, the EU committed $645 million to improve marine governance. Representatives from businesses, 112 countries and others pushed the total up to the unprecedented level.

The Our Ocean conference has accumulated some 8.7 billion euros ($10.2 billion) since it started in 2014, but the 2017 commitments exceeded expectations.

Researchers Work on Drought-tolerant Maize for Africa

GOKWE, ZIMBABWE — In Zimbabwe, researchers say they are breeding maize that is drought and heat resistant as part of efforts to fight hunger across Africa, where maize is a staple food.

In Hezekaya Village in Gokwe, about 200 kilometers west of Harare, cotton is what most people plant because it can grow in hot, dry weather. But that is slowly changing, thanks to a program of the International Maize and Wheat Improvement Center, funded by USAID and the Bill & Melinda Gates Foundation.
