Flow means ‘go’ for proper lymph system development

The lymph system provides a slow flow of fluid from tissues into the blood. It returns fluid and proteins that leak from blood vessels, provides passage for immune cells from the tissues to the blood, and hosts key niches for immune cells. How this system develops hasn’t been well understood, but now researchers have found from that the early flow of lymph fluid is a critical factor in the development of mature lymphatic vessels. —> Read More

Cataclysmic event of a certain age

At the end of the Pleistocene period, approximately 12,800 years ago­ — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas. New research has narrowed the date to a 100-year range, sometime between 12,835 and 12,735 years ago. —> Read More

Reshaping the solar spectrum to turn light into electricity

Solar energy could be made cheaper if solar cells could be coaxed to generate more power. A huge gain in this direction has been made by a team of chemists that has found an ingenious way to make solar energy conversion more efficient. The researchers combined inorganic semiconductor nanocrystals with organic molecules to ‘upconvert’ photons in the visible and near-infrared regions of the solar spectrum. —> Read More
