Life on Venus? Scientists Shed More Light on Molecules Linked to Life on Other Planets
To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical…

Lehigh researchers quantify the specific interaction between the spike protein of SARS-CoV-2 — the virus that causes COVID-19 — with the ACE2 receptors in human…
New, reversible CRISPR method can control gene expression while leaving underlying DNA sequence unchanged. Over the past decade, the CRISPR-Cas9 gene editing system has revolutionized…
A natural brilliant blue coloring has been discovered by an international team of researchers including chemists at the University of California, Davis. The new cyan…
Color changes of gold nanoparticles under the skin reveal concentration changes of substances in the body. The idea of implantable sensors that continuously transmit information…
By blocking human enzyme cathepsin L, chemical inhibitor K777 reduces coronavirus’ ability to infect cell lines; clinical trials are underway. James McKerrow, MD, PhD, dean…
Researchers find that the earliest bacteria had the tools to perform a crucial step in photosynthesis, changing how we think life evolved on Earth. The…
An ‘eat-me’ signal displayed on cell surfaces requires activation of a lipid-scrambling protein by a nuclear protein fragment. Scientists at the Institute for Integrated Cell-Material…
Like rings in a tree trunk, a narwhal’s tusk provides a window into changing conditions in the Arctic. In the Arctic, climate change and pollution…
Discovery “requires us to rethink everything we thought we knew about peroxisomes.” In his first year of graduate school, Rice University biochemist Zachary Wright discovered…
A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla…
For the first time, researchers have pinpointed what causes normal proteins to convert to a diseased form, causing conditions like CJD and Kuru. The research…
Lightning strikes — perhaps a quintillion of them, occurring over a billion years — may have provided sparks of life for the early Earth. A…
Phase 2 clinical trial could begin immediately for clofazimine, an FDA-approved drug on WHO’s List of Essential Medicines. A Nature study authored by scientists at…
Cryoprotectants are used to protect biological material during frozen storage They have to be removed when defrosting, and how much to use and how exactly…
Photosynthetic bacteria adapt to environment by using quantum mechanics to steer energy. Photosynthetic organisms harvest light from the sun to produce the energy they need…
How much did SARS-CoV-2, the virus that causes COVID-19, need to change in order to adapt to its new human host? In a research article…
Researchers design a new highly-selective tool to study “undruggable” proteins through the sugars they depend on. Sugar has been called “evil,” “toxic,” and “poison.” But…
