Phys.org / Blood pressure enzyme reveals second job: Making sulfur rings for cellular antioxidants
Antioxidants such as vitamins C and E protect cells by neutralizing free radicals, such as reactive oxygen species, before they can damage genetic material or cell membranes. Such damage can contribute to the development ...
Phys.org / Ultrathin materials could make quantum light circuits programmable
Quantum photonics could be a pivotal part of future quantum technology if the right materials can be created, a new review paper has found.
Phys.org / How cells rapidly detect viruses that fuse with their membranes
Researchers have figured out a missing piece of the puzzle of how human cells detect invading viruses and mount an immune response within an hour.
Phys.org / Webb detects ammonia and unexpected chill on a distant giant planet
Using the James Webb Space Telescope (JWST), a team of astronomers led by the University of Maryland identified water, methane and ammonia in the atmosphere of HATS-6 b, a giant planet 500 light-years from Earth. The observations ...
Phys.org / Mitochondrial protein complexes: A single amino acid can jeopardize their stability
Removing a single amino acid can determine whether new proteins assemble into stable complexes within mitochondria. An enzyme carries out this precise trimming at the start of mitochondrial proteins. Without it, numerous ...
Phys.org / Laser light enables detection of colorectal cancer biomarker in blood within minutes
Researchers often use antibodies to detect specific molecules or biological markers because they are remarkably precise at recognizing their targets. However, finding the faint signals of cancer in blood samples is a challenge ...
Phys.org / An overlooked era of cosmology is stealing the show in the quest to understand the cosmos
Could you imagine if pagers made a comeback? Sure, your smartphone would still be your notepad-flashlight-camera-personal assistant-MP3 player-wallet-social media browser. But imagine if pagers made it so easy to do that ...
Phys.org / Discovery confirms rare, switchable electrical property in widely used electronics material
A Husker research team's latest research could open the door to broader use of a class of materials whose electrical properties may someday power next-generation electronics, high-density energy storage, improved computer ...
Phys.org / How a century-old solvent can enable efficient amide synthesis
Amide bonds are chemical linkages essential to biology, medicine and materials chemistry. Peptide bonds, a class of amide bonds, link amino acids to form proteins. Amide bonds are also important in medicines and polymers. ...
Phys.org / Previously overlooked protein helps cells divide correctly
Modern technologies have made it possible to uncover a growing "hidden proteome"—proteins encoded by parts of the genome that researchers previously overlooked. Advances in sequencing and protein analysis are making it possible ...
Phys.org / Breaking and entering: How parasites prepare host cells for invasion
Before the parasite Toxoplasma gondii can invade a cell, it has to know it has reached the right place. New research from the Whitehead Institute reveals that the parasite doesn't simply recognize a ready-made doorway into ...
Phys.org / Natural proteins can guide active ingredients to diseased cells
After taking a pill, the drugs it contains are distributed throughout the body, reaching the tissues and cells affected by disease and performing their intended function. However, they also enter healthy cells, where they ...
