| High-resolution lab experiments show how cells ‘eat’ Posted: 30 Dec 2021 10:09 AM PST A new study shows how cell membranes curve to create the 'mouths' that allow the cells to consume things that surround them. |
| Leveraging space to advance stem cell science and medicine Posted: 30 Dec 2021 10:09 AM PST The secret to producing large batches of stem cells more efficiently may lie in the near-zero gravity conditions of space. Scientists have found that microgravity has the potential to contribute to life-saving advances on Earth by facilitating the rapid mass production of stem cells. |
| Healthy diet in early pregnancy reduces risk of gestational diabetes Posted: 29 Dec 2021 10:35 AM PST A healthy, comprehensive diet that lowers the body's inflammation reduces the risk of gestational diabetes mellitus, reveals a new study. |
| Smart and sustainable food packaging keeps harmful microbes at bay Posted: 29 Dec 2021 05:42 AM PST A team of scientists has developed a 'smart' food packaging material that is biodegradable, sustainable and kills microbes that are harmful to humans. It could also extend the shelf-life of fresh fruit by two to three days. |
| Venoms in snakes and salivary protein in mammals share a common origin Posted: 22 Dec 2021 06:09 PM PST A new study has found that a class of toxins found in snake and mammalian venom evolved from the same ancestral gene. |
| New grafting technique could combat the disease threatening Cavendish bananas Posted: 22 Dec 2021 12:31 PM PST Scientists have found a novel way to combine two species of grass-like plant including banana, rice and wheat, using embryonic tissue from their seeds. The technique allows beneficial characteristics, such as disease resistance or stress tolerance, to be added to the plants. |
| DNAzymes – how active DNA molecules with therapeutic potential work Posted: 22 Dec 2021 12:31 PM PST DNAzymes are precision biocatalysts that destroy unwanted RNA molecules. However, major obstacles to their use in medicine remain. Scientists have investigated with atomic resolution how DNAzymes work in real time. |
| Cancer risk across mammals: Carnivores are more prone to cancer Posted: 22 Dec 2021 12:31 PM PST We tend to talk about cancer as a human disease. While it is true that cancer seriously affects our species, we can no longer disregard the fact that other animals face this disease, just like us. Not just our pets, but wild animals too. |
| New insights into the timeline of mammal evolution Posted: 22 Dec 2021 12:30 PM PST A new study has provided the most detailed timeline of mammal evolution to date. |
| How brain cells die in prion diseases Posted: 22 Dec 2021 12:30 PM PST Prion diseases, such as Creutzfeldt-Jakob Disease (CJD), are fast-moving, fatal dementia syndromes associated with the formation of aggregates of the prion protein, PrP. How these aggregates form within and kill brain cells has never been fully understood, but a new study suggests that the aggregates kill neurons by damaging their axons, the narrow nerve fibers through which they send signals to other neurons. |
| From the oilfield to the lab: How a special microbe turns oil into gases Posted: 22 Dec 2021 12:27 PM PST Microorganisms can convert oil into natural gas, i.e. methane. Until recently, it was thought that this conversion was only possible through the cooperation of different organisms. In 2019, a researcher suggested that a special archaeon can do this all by itself, as indicated by their genome analyses. Now, researchers have succeeded in cultivating this 'miracle microbe' in the laboratory. This enabled them to describe exactly how the microbe achieves the transformation. They also discovered that it prefers to eat rather bulky chunks of food. |
