| Decoding a key part of the cell, atom by atom Posted: 10 Jun 2022 12:29 PM PDT A team led by André Hoelz has made two big leaps forward in our understanding of the nuclear pore complex, a vital cellular gateway. |
| How crops can better survive floods Posted: 10 Jun 2022 10:08 AM PDT Researchers show which signaling pathways make plants more resistant to flooding. The molecule ethylene is a warning signal for plants that they are under water and switches on the emergency supply for survival without oxygen. A team shows that plants can survive longer without oxygen when pretreated with ethylene. |
| Despite dire warnings, monarch butterfly numbers are solid Posted: 10 Jun 2022 09:02 AM PDT Scientists have been warning for quite some time that monarch butterflies were slated for extinction due to diminishing winter colonies. But a new study found that warming temperatures and growth in the summer population of monarchs has compensated for losses during the winter. Researchers did preach continued caution, as the study did show continuing declines in other species of butterflies. |
| Ningaloo corals are ill-equipped to handle future climate change Posted: 10 Jun 2022 06:13 AM PDT The relatively pristine coral populations of WA's inshore Kimberley region are better equipped to survive ocean warming than the World Heritage-listed Ningaloo Marine Park, according to a new study. |
| Dogs inhale immunotherapy to test lung cancer treatment Posted: 09 Jun 2022 12:58 PM PDT An inhaled immunotherapy successfully treated cancer in some companion dogs as part of a clinical trial conducted by oncology and veterinary researchers. Results show potential for fighting cancer in humans as well. |
| How 'green islands' help forests regenerate after fire Posted: 09 Jun 2022 12:58 PM PDT A new study characterizes the role of fire refugia -- the green islands of live trees that remain after forest fires -- in forest regeneration following large and severe fires in the High Cascade mountains of Oregon and Washington. The results of this study can help determine when human intervention in the form of tree replanting is warranted, when it isn't, where replanting efforts should be targeted and what species should be prioritized. This is important to know since overplanting can be needlessly expensive and actually place forests at increased risk of future fires. |
| 'Good' bacteria to tackle depression Posted: 09 Jun 2022 12:57 PM PDT Intestinal flora plays an important role in health -- including mental health. Researchers have shown that probiotics can support the effect of antidepressants and help to alleviate depression. |
| Drought-exposure history improves recovery of grassland communities from subsequent drought Posted: 09 Jun 2022 12:57 PM PDT When a plant community is exposed to drought, the different species undergo evolutionary changes. An international study with UZH participation now shows that this leads to improved resilience to future drought stress over time. |
| Posted: 09 Jun 2022 10:19 AM PDT Extensively used grassland is host to a high degree of biodiversity, and performs an important climate protection function as a carbon sink and also serves for fodder and food production. However, these ecosystem services are jeopardized if productivity on these lands is maximized and their use therefore intensified. Researchers have now described how satellite data and machine learning methods enable to assess land-use intensity. |
| Targeting mosquito spit to halt Yellow Fever, Dengue and Zika Posted: 08 Jun 2022 01:13 PM PDT A molecule in mosquito spit has been identified as a potential new target for vaccination against a range of diseases for which there is no protection or medicine. Researchers have discovered that the molecule, called sialokinin, makes it easier for a number of viruses to pass from mosquitoes to human, where they can then take hold -- leading to unpleasant and potentially deadly diseases including Yellow Fewer, Dengue and Zika. |
| Kelp connecting Southern Ocean coasts, genomics reveals Posted: 08 Jun 2022 08:24 AM PDT The DNA of kelp has enabled scientists to show just how interconnected coastal communities of the Southern Ocean are. A new study carried out genomic analyses of bull kelp washed up over decades in Antarctica, New Zealand and Australia. |
| Separating tiny bacteria by shape: Simple tech for E. coli sorting Posted: 08 Jun 2022 06:14 AM PDT Researchers use a viscoelastic material flowing through a microfluidic chip to sort E. coli bacteria based on their degree of elongation. By using this 'lab-on-a-chip' device, scientists may be able to set up more reproducible experiments, as well monitor the progression of bacterial infections at a patient's bedside. |
