| The European drought event from 2018 to 2020 was the most intense in over 250 years Posted: 16 May 2022 09:40 AM PDT These were days, months and years that many will come to remember: the drought from 2018 to 2020. An international team of researchers has succeeded in categorizing the historical dimensions of this event. Based on their findings, no drought covering such a large area for an extended period and coinciding with warmer temperature has occurred in Europe since the middle of the 18th century. The years from 2018 to 2020 thus represent a new benchmark for droughts. Because such an unprecedented event is likely to occur more frequently in the future, the scientists urgently recommend the development and implementation of suitable, regionally adapted drought prevention measures. |
| Perception-based nanosensor platform could advance detection of ovarian cancer Posted: 16 May 2022 09:39 AM PDT Ovarian cancer kills 14,000 women in the United States every year. It's the fifth leading cause of cancer death among women, and it's so deadly, in part, because the disease is hard to catch in its early stages. Patients often don't experience symptoms until the cancer has begun to spread, and there aren't any reliable screening tests for early detection. |
| Amazon deforestation threatens newly discovered fish species in Brazil Posted: 16 May 2022 09:39 AM PDT Researchers have discovered and described two new species of Amazonian fish -- one with striking red-orange fins and the other so small it is technically considered a miniature fish species. Both species inhabit waters located at the bleeding edge of human encroachment into the Amazon rainforest roughly 25 miles north of the Brazilian city of Apuí. The study's authors said that ongoing deforestation in the region places these roughly inch-long fish, part of a group known colloquially as the South American darters, in imminent danger of extinction. |
| CRISPR now possible in cockroaches Posted: 16 May 2022 09:39 AM PDT Researchers have developed a CRISPR-Cas9 approach to enable gene editing in cockroaches, according to a new study. The simple and efficient technique, named 'direct parental' CRISPR (DIPA-CRISPR), involves the injection of materials into female adults where eggs are developing rather than into the embryos themselves. |
| From degrowth to a sustainable food system transformation Posted: 16 May 2022 09:39 AM PDT Proponents of degrowth have long argued that economic growth is detrimental to the environment. Now, scientists show that concerning the food sector, curbing growth alone would not make our food system sustainable -- but changing what we eat and putting a price on carbon would. |
| Ethical challenges in microbiome research Posted: 16 May 2022 09:39 AM PDT A human rights activist and a group of anthropologists and human biologists are casting a critical lens on the way that microbiome research is conducted with Indigenous peoples. |
| Precursor of spine and brain forms passively Posted: 16 May 2022 09:39 AM PDT Researchers have conducted a detailed study of neurulation -- how the neural tube forms during embryonic development. They conclude that this happens less actively than previously thought. This also has implications for understanding defects such as spina bifida. |
| Chinese penduline tit buries eggs to prevent them from blowin' in the wind Posted: 16 May 2022 09:38 AM PDT Many animal species bury their eggs, for a number of different reasons. While it is firmly established that Eurasian penduline tits bury them because of sexual conflict, their Chinese counterparts seem to have an entirely different reason. Experimental manipulations show that for these birds burial prevents the eggs from falling out of the nest in strong winds. |

| Posted: 16 May 2022 05:17 AM PDT Photoreduction of CO2 into transportable fuel like formic acid (HCOOH) is a great way of dealing with CO2's rising levels in the atmosphere. To aid in this mission, a research team chose an easily available iron-based mineral and loaded it onto an alumina support to develop a catalyst that can efficiently convert CO2 into HCOOH with ~90% selectivity! |
| Artery stiffness may predict Type 2 diabetes risk better than BP and standard risk factors Posted: 16 May 2022 05:17 AM PDT Analysis of more than 11,000 people investigated whether high blood pressure or arterial stiffness may be a better predictor of future Type 2 diabetes risk. Results found that adults with increased arterial stiffness had a higher risk of developing Type 2 diabetes, regardless of their hypertension status when added to standard risk factors. More research is needed to determine the association among Type 2 diabetes, high blood pressure and arterial stiffness, and to provide insight into future prevention strategies to reduce the risk of Type 2 diabetes. |
| Smart pacifier developed to monitor infant health in the hospital Posted: 16 May 2022 05:17 AM PDT A wireless, bioelectronic pacifier could eliminate the need for invasive, twice-daily blood draws to monitor babies' electrolytes in Newborn Intensive Care Units or NICUs. This smart pacifier can also provide more continuous monitoring of sodium and potassium ion levels. These electrolytes help alert caregivers if babies are dehydrated, a danger for infants, especially those born prematurely or with other health issues. Researchers tested the smart pacifier on a selection of infants in a hospital, and the results were comparable to data gained from their normal blood draws. |
