| New technology enables rapid sequencing of entire genomes of plant pathogens Posted: 15 May 2021 06:11 AM PDT Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases. |
| Harvesting light like nature does Posted: 15 May 2021 06:11 AM PDT A new class of bio-inspired two-dimensional (2D) hybrid nanomaterials mimic the ability of photosynthetic plants and bacteria. |
| Path of light in photosynthesis traced Posted: 15 May 2021 06:11 AM PDT Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food. |
| New cyanobacteria species spotlights early life Posted: 15 May 2021 06:09 AM PDT Cyanobacteria first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms. Researchers have discovered a new species of cyanobacteria, Anthocerotibacter panamensis, which could help illuminate how photosynthesis evolved to create the world as we know it. |
| Mammals can use their intestines to breathe Posted: 14 May 2021 10:42 AM PDT Rodents and pigs share with certain aquatic organisms the ability to use their intestines for respiration, finds a study publishing May 14th in the journal Med. The researchers demonstrated that the delivery of oxygen gas or oxygenated liquid through the rectum provided vital rescue to two mammalian models of respiratory failure. |
| Climate change threatens one-third of global food production Posted: 14 May 2021 10:41 AM PDT New research assesses just how global food production will be affected if greenhouse gas emissions are left uncut. |
| Which animals will survive climate change? Posted: 14 May 2021 10:41 AM PDT Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes. Their findings could help scientists forecast the evolutionary future of these populations. |
| Epigenetic changes drive the fate of a B cell Posted: 13 May 2021 02:35 PM PDT B cells are the immune cells responsible for creating antibodies, and most produce antibodies in response to a pathogen or a vaccine. A small subset of B cells instead spontaneously make antibodies that perform vital housekeeping functions. Understanding how epigenetics spur these differences in such similar cells is an important fundamental question in immunology. |
| Force-sensing PIEZO proteins are at work in plants, too Posted: 13 May 2021 02:35 PM PDT A family of proteins that sense mechanical force--and enable our sense of touch and many other important bodily functions--also are essential for proper root growth in some plants, according to a study led by scientists at Scripps Research and Howard Hughes Medical Institute. |
