| Hormones contribute to sex disparities in bladder cancer, study shows Posted: 09 Jun 2022 04:50 PM PDT Male sex hormones interfere with the body's ability to fight bladder cancer, likely explaining why males experience higher cancer rates and more deadly disease, according to a new study. |
| 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. |
| Maintaining the right niche for blood cell development Posted: 09 Jun 2022 12:57 PM PDT Researchers have identified the role of transcription factors Runx1 and Runx2 in the inhibition of fibrosis, the abnormal build-up of connective tissue with severe hematopoietic defects, in the bone marrow. Mice lacking both Runx1 and Runx2 in CAR cells, a major component of the hematopoietic stem cell niche, demonstrated severe myelofibrosis and defects in the production of blood cells. Runx1 and Runx2 may act as potential targets in the diagnosis and treatment of myelofibrosis. |
| Impostor Phenomenon: When self-doubt gets the upper hand Posted: 09 Jun 2022 12:57 PM PDT People who systematically underestimate themselves and their own performance suffer from so-called Impostor Phenomenon. They think that any success is due to external circumstances or just luck and chance. Those people live in constant fear that their 'deception' will be exposed. Psychologists now show that even under real-life conditions the phenomenon can appear regardless of age, gender, and intelligence. |
| Hydrogen peroxide from tea and coffee residue: New pathway to sustainability Posted: 09 Jun 2022 12:57 PM PDT Hydrogen peroxide (H2O2) is an important chemical, with a wide variety of applications. However, the current method used to manufacture H2O2 is expensive and generates a considerable amount of waste, making it an unsustainable approach. In this study, a group of researchers produced H2O2 from waste coffee grounds and tea leaves, and then demonstrated its industrial use. Their novel method proved to be simple, cost-effective, and most importantly, sustainable. |
| '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. |
| Climate economics: Policies change people Posted: 09 Jun 2022 12:57 PM PDT The makers of climate policy should rethink how people think: Researchers show that abiding by climate-friendly policies actually changes the way people think about what they do. People's preferences are more dynamic than textbook economics often assumes. The researchers' advice to policy makers is to take changing preferences into account when tailoring policies like carbon taxes or building low-carbon infrastructure. |
| 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. |
| Ultra-thin, flexible probe provides neural interface that's minimally invasive and long-lasting Posted: 09 Jun 2022 10:20 AM PDT Researchers have developed a tiny, flexible neural probe that can be implanted for longer time periods to record and stimulate neural activity, while minimizing injury to the surrounding tissue. The probe would be ideal for studying small and dynamic areas of the nervous system like peripheral nerves or the spinal cord. |
| New feedback system can improve efficiency of fusion reactions Posted: 09 Jun 2022 10:19 AM PDT Scientists have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The improved technique protects internal parts from damage by instabilities and allows tokamaks to operate for longer without pausing. |
| 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. |
| The interferon gamma receptor pathway is necessary for CAR T-cell mediated killing in solid tumors Posted: 09 Jun 2022 10:19 AM PDT Researchers have discovered that the interferon gamma receptor (IFNgR) signaling pathway is critical for susceptibility of glioblastoma tumors to killing by CAR T-cell immunotherapy. |
