Complex molecules could hold the secret to identifying alien life
A new system capable of identifying complex molecular signatures could aid in the search for alien life in the universe and could even lead to the creation of new forms of life in the laboratory, scientists say. University of Glasgow researchers have developed a new method called Assembly Theory which can be used to quantify how assembled or complex a molecule is in the laboratory using techniques like mass spectrometry.

The first nuclear reactor, explained
In 1942, the Manhattan Project needed to create a chain reaction-a crucial step towards proving that it would be possible to make an atomic bomb. They achieved this first sustained chain reaction , the first created by humans, on Dec. 2, 1942, in a squash court at the University of Chicago. Nicknamed "Chicago Pile-1," the world's first nuclear reactor kicked off the Atomic Age and has a complicated legacy, including the rise of both nuclear energy and nuclear weapons.

Diamonds engage both optical microscopy and MRI for better imaging
The microdiamonds used as biological tracers are about 200 microns across, less than one-hundredth of an inch. They fluoresce red but can also be hyperpolarized, allowing them to be detected both optically - by fluorescence microscopy - and by radio-frequency NMR imaging, boosting the power of both techniques.

Building molecules like Tinkertoys? A breakthrough study may pave the way
Molecules are the building blocks for our modern world, from phones to cars to Doritos. But coming up with new ones is still an incredibly costly and time-consuming process. A group of University of Chicago chemists wants to find a better way. "If you look at a diagram of a molecule, it seems like you should be able to just snap them together like Tinkertoys, but you can't," said Asst.

Discovery of methanol in a 'warm' planet-forming disk
Discovery of methanol in a ’warm’ planet-forming disk
Astronomers have identified the molecule methanol in the 'warm zones' of a protoplanetary disk circling a star about 360 light years from Earth. The finding is significant because although methanol - CH3OH - is one of the simpler complex carbon-based molecules, it is a precursor chemical involved in the creation of more complex substances such as amino acids and proteins, the building blocks of life.

Firefighting chemicals found in sea lion and fur seal pups
Firefighting chemicals found in sea lion and fur seal pups
The chemicals - which can cause developmental and reproductive defects, cancer, and can compromise immunity - represent another challenge to conserving the endangered Australian sea lion. A chemical that the NSW government has recently partially banned in firefighting has been found in the pups of endangered Australian sea lions and in Australian fur seals.

Tracking down the tiniest of forces: how T cells detect invaders
Tracking down the tiniest of forces: how T cells detect invaders
T cells use their antigen receptors like sticky fingers - a team from TU Wien and MedUni Vienna was able to observe them doing so. T-cells play a central role in our immune system: by means of their so-called T-cell receptors (TCR) they make out dangerous invaders or cancer cells in the body and then trigger an immune reaction.

How diet controls RNA maturation
How diet controls RNA maturation
Two UNIGE teams have discovered a new mechanism for regulating RNA maturation that depends on diet. Particularly sensitive to chemical modifications, messenger RNAs (mRNAs) are molecules responsible for transmitting the information encoded in our genome, allowing for the synthesis of proteins, which are necessary for the functioning of our cells.

How acidic are atoms?
How acidic are atoms?
The acidity of molecules can be easily determined, but until now it was not possible to measure this important property for atoms on a surface. With a new microscopy technique from the Vienna University of Technology (TU Wien), this has now been achieved. The degree of acidity or alkalinity of a substance is crucial for its chemical behavior.

The Future Looks Bright for Infinitely Recyclable Plastic
A new environmental and technological analysis suggests that a revolutionary eco-friendly plastic is almost ready to hit the shelves Plastics are a part of nearly every product we use on a daily basis. The average person in the U.S. generates about 100 kg of plastic waste per year, most of which goes straight to a landfill.
