| Posted: 27 May 2022 09:13 AM PDT Researchers have succeeded in understanding the biosynthetic mechanisms for the production of the natural product cyanobacterin, which is produced in small quantities by the cyanobacteria Scytonema hofmanni. In the process, they also discovered a new class of enzymes for building carbon-carbon bonds. The (bio)chemists are thus significantly expanding the biocatalytic repertoire currently known from Nature and are opening up new, sustainable biotechnological applications in medicine and agriculture. |
| T cell warriors need their R & R Posted: 27 May 2022 09:13 AM PDT T cells, biology textbooks teach us, are the soldiers of the immune system, constantly on the ready to respond to a variety of threats, from viruses to tumors. However, without rest and maintenance T cells can die and leave their hosts more susceptible to pathogens, scientists report. |
| An arms race that plays out in a single genome Posted: 27 May 2022 09:13 AM PDT We often think of biological arms races occurring between the immune system and pathogens, or predator and prey, but biologists have now discovered an example that plays out within a single genome. Their work in fruit flies may have implications for key biological processes in humans, including fertility and even cancer. |
| Ancient viral elements embedded in human genome not from fossil retrovirus Posted: 27 May 2022 07:12 AM PDT Many types of animals, including humans, successfully coexist with retroviruses, and we know that ancient retrovirus viral elements can even be found within our genome. We also know that these endogenous retroviruses can be utilized for development and evolution. However, uncontrolled endogenous retroviruses may be a cause of disease in the human body. Now, researchers have discovered that endogenous retroviruses in our genome may pose a risk in regenerative medicine. |
| Siberian tundra could virtually disappear by mid-millennium Posted: 27 May 2022 07:12 AM PDT Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and fauna. Experts have now prepared a computer simulation of how these woods could spread in the future, at the tundra's expense. |
| Posted: 27 May 2022 05:52 AM PDT Artificial Intelligence (AI) can track the health of coral reefs by learning the 'song of the reef', new research shows. |
| British coral predicted to be resilient to climate change Posted: 27 May 2022 05:52 AM PDT An iconic coral species found in UK waters could expand its range due to climate change, new research shows. |
| 'Fuel of evolution' more abundant than previously thought in wild animals Posted: 26 May 2022 11:15 AM PDT The raw material for evolution is much more abundant in wild animals than we previously believed, according to new research. |
| More young people begin recreational cannabis use illegally in states that legalize it Posted: 26 May 2022 06:55 AM PDT Once a state legalizes recreational cannabis and increase in youth using it illegally occurs, report researchers. |
| Cryogenic electron microscopy reveals drug targets against common fungus Posted: 25 May 2022 12:17 PM PDT Scientists have used single-particle cryogenic electron microscopy to determine the structure of the ribosome of Candida albicans. Their results reveal a potential target for new drugs. |
| Species thrive through social connections Posted: 25 May 2022 07:30 AM PDT Community diversity increases with an increased number of interactions between different species, but the mean interaction strength decreases. The interaction capacity hypothesis shows that interspecies connectance may play an important role and might help understand and predict community diversity. |
| Some monkeys might pull a poker face Posted: 25 May 2022 07:29 AM PDT The human facial action coding system, or FACS, has been developed as a tool for cross-species systematic comparisons of facial muscles to help interpret the resulting facial expressions of the common marmoset. The new CalliFACS detected facial mobility in marmosets similar to other non-human primates. |
