MIT researchers developed a desalination system that is more efficient and less expensive than previous methods. In addition to providing fresh water, the process could be used to treat contaminated wastewater or generate steam for sterilizing medical instruments, all without requiring a power source other than…
Energy use is declining in some countries, despite economic growth.
The U.S spent $25.8 billion on Project Apollo ($309 billion when adjusted for inflation). This dataset provides annual expenditures and additional cost…
Many countries ship plastic waste overseas. How much of the world’s waste is traded, and how big is its role in the pollution of our oceans?
All energy production takes up land, but which sources use the most land, and which use it most efficiently?
MIT engineers have flown the first silent, fuel-free “ion plane.” The light aircraft is the first plane to fly with no propellers, turbine blades, or other moving parts.
New evidence suggests anyone infected with COVID is at higher risk for heart issues—a risk that persists even in relatively healthy people long after the illness has passed.
[EDITOR'S NOTE: In marking this year's 25th anniversary of Edge , we are presenting original lectures from eminent scientists and other thinkers in the empirical world who are changing the way we think about science and our place in the world.]
The FAA delivered September 1 the long-sought approval of an unleaded fuel now cleared to power every spark-ignition engine on any airframe in the general aviation fleet.
The MIT spinout Frequency Therapeutics uses a new kind of druggable regenerative therapy that targets progenitor cells to create hair cells of the inner ear and reverse hearing loss.
Per- and polyfluoroalkyl substances (PFAS) are man-made hazardous chemicals that are spread globally in the atmosphere and as a result they can be found in the rainwater and snow in even the most remote locations on Earth. During the last 20 years, guideline values for PFAS in drinking water, surface waters and soils…
DURHAM, N.C. -- In 1923, lead was first added to gasoline to help keep car engines healthy. However, automotive health came at the great expense of our own well-being.
The soleus muscle in the calf can do big things to improve the metabolic health in the rest of your body if activated correctly. Now UH researchers are pioneering the “soleus pushup” which elevates muscle metabolism for hours, even while sitting.
The world produces more food than ever, but the amount of land we use is now falling. This means we can feed more people while restoring wild habitat.
Explore the diversity of wildlife across the planet. What are species threatened with? What can we do to prevent biodiversity loss?
A study of archival images from Zwicky Transient Facility shows an increase in satellite streaks.
Why don’t rails get hot in Europe? The truth is they do.
All their wonders in one table
New research suggests the invasive but relatively harmless Joro spider could colonize the entire East Coast.
Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study from MIT. Biologists found fasting dramatically improves stem cells’ ability to regenerate, in both aged and young mice.
