Scientists have found a new way to analyze the chemistry of the moon’s soil using a single grain of dust brought back by Apollo 17 astronauts in 1972. Their technique can help us learn more about conditions on the surface of the moon and formation of precious resources like water and helium there.

Back in 1972, NASA sent their last team of astronauts to the Moon in the Apollo 17 mission. These astronauts brought some of the Moon back to Earth so scientists could continue to study lunar soil in their labs. Since we haven’t returned to the Moon in almost 50 years, every lunar sample is precious. We need to make them count for researchers now and in the future...

Chronic inflammation, which results when old age, stress or environmental toxins keep the body’s immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer’s and Parkinson’s to diabetes and cancer.

Now, scientists at the University of California, Berkeley, have identified a molecular “switch” that controls the immune machinery responsible for chronic inflammation in the body. The finding, which appears online Feb. 6 in the journal Cell Metabolism, could lead to new ways to halt or even reverse many of these age-related conditions.

Engineers with the University of Cincinnati have created a tiny portable lab that plugs into your phone, connecting it automatically to a doctor’s office through a custom app UC developed. The lab the size of a credit card can diagnose infectious diseases such as coronavirus, malaria, HIV or Lyme disease or countless other health conditions like depression and anxiety.

The patient simply puts a single-use plastic lab chip into his or her mouth then plugs that into a slot in the box to test the saliva.

The so-called “Cocoon Galaxy” not only has a unique shape, it has a rare double-nucleus structure, astronomers report in a new paper.

After studying data from optical and radio telescopes based on the ground and in space, a team of astronomers determined that a galaxy known as NGC 4490 (and nicknamed the “Cocoon Galaxy” because of its shape) has “a clear double nucleus structure,” according to their paper.

One nucleus can be seen in optical wavelengths. The other is hidden in dust and can only be seen in infrared and radio wavelengths.

The...
