Detecting antibodies with glowing proteins, thread and a smartphone

Approach could provide a small, inexpensive alternative to expensive, sophisticated instruments in labs

22-Jun-2020

To defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the body itself. In a new proof-of-concept study in ACS Sensors, researchers describe a new system for ...

New research shows how complex chemistry may be relevant to origins of life on Earth

09-Jun-2020

Chemists have long sought to understand the origins of life, with one popular model suggesting life began when simple RNA molecules capable of copying themselves formed spontaneously in the primitive environment. How this happened exactly is fraught with difficulties. New research by a team of ...

A molecular pressure cooker tenderizes tough pieces of protein and helps to bite off

04-May-2020

Proteins are composed of amino acids connected by amide bonds. The amide bond exhibits high chemical stability and has a planar structure around the bond. Although the high stability of amide bond is indispensable to maintain protein functions, it is problematic to convert the building block into ...

Making Puffer Fish Toxin in a Flask

Total synthesis of tetrodotoxin

10-Mar-2020

In Japan, puffer fish is considered a delicacy, but the tickle to the taste buds comes with a tickle to the nerves: fugu contains tetrodotoxin, a strong nerve toxin. In low doses, tetrodotoxin is shown in clinical trials to be a replacement for opioids for relieving cancer related pain. In the ...

New study on a recently discovered chlorophyll molecule could be key to better solar cells

Scientists uncover location and functions of a new type of chlorophyll molecule for the first time

23-Jan-2020

All living organisms need energy for their survival, and this energy indirectly comes from the sun. Some organisms, such as plants, cyanobacteria, and algae, are capable of directly converting this light energy into chemical energy via a process called "photosynthesis". These photosynthetic ...

Let there be light: Synthesizing organic compounds

23-Sep-2019

Every biological reaction is a chemical reaction. The exchange of carbon dioxide for oxygen in our lungs and blood cells, for example, is caused by molecules releasing chemicals and reforming with new ones. The uncontrolled replication of cancerous cells is the result of broken chemical compounds ...
