| Study shows how bioactive substance inhibits important receptor Posted: 25 Mar 2022 09:27 AM PDT The A2A receptor regulates how vigorously the innate immune system attacks diseased cells. Researchers have now been able to show for the first time how an important inhibitor binds to the receptor. In the future, the results will facilitate the targeted search for molecules that give the innate immune system more punch. These could for instance be used in the fight against cancer, but also against brain diseases such as Alzheimer's or Parkinson's disease. |
| Half of all women experience false positive mammograms after 10 years of annual screening Posted: 25 Mar 2022 09:27 AM PDT Half of all women experience a false positive mammogram after 10 years of annual breast cancer screening with 3D mammography, a UC Davis-led study estimates. This risk was lower for women who had mammograms every other year. 3D screening showed slightly lower false positive results than standard mammography. |
| Large study challenges the theory that light alcohol consumption benefits heart health Posted: 25 Mar 2022 09:27 AM PDT In an observational analysis of UK Biobank participants, light to moderate drinkers had the lowest heart disease risk, followed by people who abstained from drinking; however, light to moderate drinkers tended to have healthier lifestyles than abstainers, which likely accounted for their better heart health. Genetic evidence in this same population suggested that all levels of alcohol intake are associated with increased cardiovascular risk. Notably, the risk of cardiovascular disease linked to light alcohol consumption was modest but rose exponentially with higher intake, even at intake levels currently endorsed as 'low risk.' |
| Study finds neurons that encode the outcomes of actions Posted: 25 Mar 2022 09:27 AM PDT A group of neurons in the brain's striatum encodes information about the potential outcomes of different decisions. These cells become particularly active when a behavior leads a different outcome than what was expected, which the researchers believe helps the brain adapt to changing circumstances. |
| Posted: 25 Mar 2022 09:27 AM PDT Researchers have developed a novel super-hygroscopic material that enhances sweat evaporation within a personal protective suit, to create a cooling effect for better thermal comfort for users such as healthcare workers and other frontline officers. With this innovation, users will feel 40% cooler and their risk of getting heat stroke is lowered significantly. |
| Like father like child: male parents lead young birds on first migration Posted: 25 Mar 2022 09:27 AM PDT GPS tracking of Caspian terns showed that male parents carry the main responsibility for leading young during their first migration from the Baltic Sea to Africa. |
| Vagus nerve stimulation lowers costs of care for children with uncontrolled epilepsy Posted: 25 Mar 2022 09:26 AM PDT A new study has examined a population of pediatric patients with drug-resistant epilepsy. For these patients, the study found that the patients who received vagus nerve stimulation (VNS), when used with anti-seizure medications (ASM), had lower hospital costs compared to the use of ASM alone. The study found that the patients treated with ASM plus VNS had savings of over $3,000 of epilepsy-related annual costs per year, compared to treatment with ASM only. |
| Innovative AI technology aids personalized care for diabetes patients needing complex drug treatment Posted: 25 Mar 2022 09:24 AM PDT Medical researchers have developed and tested an AI method to improve care for patients with type 2 diabetes mellitus who need complex treatment. The new AI method analyzed electronic health record data across Utah and Indiana and learned generalizable treatment patterns of type 2 diabetes patients with similar characteristics. Those patterns can now be used to help determine an optimal drug regimen for a specific patient. |
| The hardy wild grass that could save our bread Posted: 25 Mar 2022 06:39 AM PDT An obscure species of wild grass contains 'blockbuster' disease resistance that can be cross bred into wheat to give immunity against one of the deadliest crop pathogens. |
| Quantum physics sets a speed limit to electronics Posted: 25 Mar 2022 06:39 AM PDT Semiconductor electronics is getting faster and faster - but at some point, physics no longer permits any increase. The speed can definitely not be increased beyond one petahertz (one million gigahertz), even if the material is excited in an optimal way with laser pulses. |
| Rapid glacial advance reconstructed during the time of Norse occupation in Greenland Posted: 25 Mar 2022 06:39 AM PDT The Greenland Ice Sheet is the second largest ice body in the world, and it has the potential to contribute significantly to global sea-level rise in a warming global climate. Understanding the long-term record of the Greenland Ice Sheet, including both records of glacial advance and retreat, is critical in validating approaches that model future ice-sheet scenarios. However, this reconstruction can be extremely challenging. A new study has reconstructed the advance of one of the largest tidewater glaciers in Greenland to provide a better understanding of long-term glacial dynamics. |
| Posted: 25 Mar 2022 06:39 AM PDT A novel class of bed net that kills mosquitoes resistant to traditional insecticides by making them unable to move or fly, significantly reduces malaria infection in children, according to new research published in The Lancet. Unlike other insecticides which kill the mosquito via the nervous system, the effects of the new bed net mean the mosquito dies from starvation or being unable to fend for itself. |
| Simply printing high-performance perovskite-based transistors Posted: 25 Mar 2022 06:39 AM PDT A research team develops high performing p-type transistor using perovskite. Solution-processed metal halide perovskite transistors can now be printed. |
| Scientists develop coated probiotics that could be effectively delivered into the human gut Posted: 25 Mar 2022 06:38 AM PDT Scientists have developed probiotics with a unique edible coating that ensures the beneficial bacteria successfully reach the intestine once they are ingested. |
| 'Hot' spin quantum bits in silicon transistors Posted: 25 Mar 2022 06:38 AM PDT Quantum bits (qubits) are the smallest units of information in a quantum computer. Currently, one of the biggest challenges in developing this kind of powerful computer is scalability. A research group has now made a breakthrough in this area. |
| https://www.uni-goettingen.de/en/3240.html?id=6625 Posted: 24 Mar 2022 03:47 PM PDT Tropical peatlands are one of the most efficient carbon sinks. The flipside is that they can become massive emitters of carbon if they are damaged, for instance by land use change, degradation or fire. This can lead to faster climate warming. Researchers now show how peatland in the coastal areas in Sumatra and Borneo in Indonesia developed over thousands of years and how climate and sea level influenced their dynamics throughout. |
| Therapy can support medication treatment for opioid use disorder Posted: 24 Mar 2022 03:47 PM PDT Receiving psychosocial and behavioral therapy alongside medications for opioid use disorder leads to better treatment engagement and continuity, according to researchers. |
| Spinal fluid sampling used to track treatment response in pediatric glioma Posted: 24 Mar 2022 03:47 PM PDT Treatment for glioma has long relied on MRI imaging to track tumor markers and treatment response. But new findings suggest a new method could provide additional data about tumor markers before changes appear on an MRI, indicating possible strategies to help clinicians address this aggressive form of cancer. |
| Scientists develop the largest, most detailed model of the early universe to date Posted: 24 Mar 2022 03:47 PM PDT Thesan is a new universe simulation that models the first billion years of the universe with the highest resolution, over the largest volume, to date. |
| Scientists shave ‘hairs’ off nanocrystals to improve their electronic properties Posted: 24 Mar 2022 03:46 PM PDT A new study introduces a breakthrough in making nanocrystals function together electronically. The research may open the doors to future devices with new abilities. |
| Win-wins in environmental management hard to find Posted: 24 Mar 2022 09:25 AM PDT When a booming marine fishery can increase its shrimp catch while also reducing unintentional bycatch of turtles --t hat's an example of what environmental scientists and managers call a 'win-win.' Models often predict this ideal outcome is achievable, yet stakeholders rarely see it manifest in the real world. |
