SCIENCE

A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research. Photonic crystals are generally made by drilling millions of...

For decades, marine chemists have faced an elusive paradox. The surface waters of the world's oceans are supersaturated with the greenhouse gas methane, yet most species of microbes that can generate the gas can't...

Synthetic biology allows scientists to design genetic circuits that can be placed in cells, giving them new functions such as producing drugs or other useful molecules. However, as these circuits become more complex, the...
Robots teach themselves

The common, and recurring, view of the latest breakthroughs in artificial intelligence research is that sentient and intelligent machines are just on the horizon. Machines understand verbal commands, distinguish pictures, drive cars and play...

For scientists listening in on the faint whispers of brain neurons, a first-ever robotic technique for cleaning the tiny devices that record the signals could facilitate a new level of automation in neuroscience research....

The genetic code that allows cells to store the information necessary for life is well-known. Four nucleotides, abbreviated A, C, G, and T, spell out DNA sequences that code for all of the proteins...
circadian rhythm

Giles E. Duffield, University of Notre Dame Have you ever wondered why you don’t feel tired until late at night but your spouse is fast asleep at 10 p.m. and wakes spontaneously at 6 a.m.? We...
Universal Healthcare

Amidst the partisan rancor and the unusual tilt toward questions on civility during the second and third presidential debates, Hillary Clinton and Donald Trump drew the attention of health experts when they articulated their...

We humans like to think of ourselves as on the top of the heap compared to all the other living things on our planet. Life has evolved over three billion years from simple one-celled...

By Huaichen Zhang*, Camilo C. M. Rindt, David M. J. Smeulders, and Silvia V. Nedea*  Abstract (image above) Nanoscale carbon structures such as graphene and carbon nanotubes (CNTs) can greatly improve the effective thermal conductivity of thermally...
Alcoholism

About 17 million adults and more than 850,000 adolescents had some problems with alcohol in the United States in 2012. Long-term alcohol misuse could harm your liver, stomach, cardiovascular system and bones, as well...

MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior. In a study of mice, the researchers found that activating these cells stimulates overeating and...
