New data show that the first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated. Contaminated…
Two newly published studies reveal evidence for how the genetic code developed in two distinct stages to help primordial chemicals evolve into cells. Chapel Hill,…
While exploring whether a structured RNA molecule from a virus that infects eukaryotic cells could function in bacteria, scientists found that it could initiate protein…
New research yields insight into generating antibodies that target different strains of HIV, suggesting that sequentially administering several different forms of a potential HIV vaccine…
New research from Yale University provides insights into the conformational space that EF-G samples on the ribosome and reveals that tRNA translocation on the ribosome…
Using multidimensional gas chromatography coupled to time-of-flight mass spectrometry, researchers have detected 10 aldehydes laboratory samples which were created to simulate material found in interstellar…
Two new research papers from Rice University detail how synthetic collagen fibers self-assemble via their sticky ends. Collagen is the most common protein in mammals,…
At this year’s American Society for Bone and Mineral Research conference, NASA scientists shared what they’ve learned from a half century of related space flight…
Researchers used Escherichia coli to interrupt the biological process that turns fatty acids into cell membranes, channeling the fatty acids along a different biological pathway…
Researchers identify a key mechanism to how basic muscle architecture is built, finding that mechanical tension is the essential trigger. Skeletal muscles are built from…
Using bacteria, Yale researchers rewrite most of the genetic instructions that encode all 20 amino acids, creating a specific 21st amino acid. Yale researchers have…
By targeting mitochondria with the anticancer drug cisplatin, chemists have developed a new way to kill cancer cells that have shown resistance to cisplatin. Cisplatin…
Scientists at Rice University have created cerium oxide nanospheres that could help treat injuries, guard against radiation-induced side effects of cancer therapy and protect astronauts…
New research from biochemists at the UNC School of Medicine offers an intriguing new view on how life began, challenging current assumptions about the origins…
An international team of researchers has discovered a new protein called ceramide-1 phosphate transport protein (CPTP) that has the potential to aid in the treatment…
A newly published stem cell study from UC Davis uncovers the brain-protective powers of astrocytes, finding that astrocytes can protect brain tissue and reduce disability…
Scientists have discovered that “supercooled” water transforms into a new form of liquid, a “liquid-liquid” phase transition that is important for understanding basic processes during…
Researchers at the Lawrence Berkeley National Laboratory have imaged the atom-by-atom structure of the ribosome attached to a molecule that controls its motion for the…
