New study: Steps toward understanding the ferritin ‘nanocage’
Proteins are the building blocks of cells, tissues, and the larger creations of life (such as humans), which makes them important. That doesn’t make them easy to understand. In fact, studies such as...

Extending life with diet or insulin has trade-offs
Over the last decade or so, two of the most promising avenues of research in gerontology (the study of aging) and the search for means of extending human life have been on the effects of restricting...

A new role for a key cell protein
We know from our experience, intuition, and scads of studies that the body reacts to stress – often negatively. For the most part, long term stress is harmful. There are many muscular, neurological,...

New proteomics: Fat isn’t inactive
Most people think of fat as stuff that just sits there – like the pendulous beer belly or the not so cute love handles. Scientists too have long thought of fat…and fat cells…as simply repositories of...

Stem cells: Myc does much more
To put it mildly, not thinking beyond assumptions can lead to surprises. This also applies to science. For many years scientists thought that the gene known as Myc (“mick”) plays a role in causing...

Discovery: An immune system within cells
The human body has a pretty good immune system. Because it’s so crucial to our health, scientists and doctors have been studying the immune system intensely for a long time. A good deal is known about...

Proteins and quantum transition: Instant shape-shifting
Every once in a great while a piece of very interesting science comes along, quietly, until more and more people notice that not only is important but it may be right. Then scientists get into high...

Neuroscience: Memory tied to a specific protein complex
At times it must seem to neuroscientists that the enigma of memory reveals its secrets to them as if they were the proverbial blind men describing an elephant. “Ah yes, it has a hose, a very thick...

Synthetic biology: Making new proteins with E. coli by adding DNA
Sometimes big advances in science happen without much public notice. That’s often because at the time they didn’t look like big advances in science, or just as likely, they were considered marginally...

DNA nanosensors
Not all sensors are electronic, or at least if you expand the scope of sensor technology, measurement techniques (which is what sensor technology is about) can also be chemical or physical, among other...
