New, peer-reviewed research published today by the Social Analytics Lab at the MIT Initiative on the Digital Economy in the prestigious Proceedings of the National Academy of Sciences shows the devastating cost of the current chaotic and uncoordinated reopening of states and cities across the US. The study, which used data from mobile phones, network connections through social media and census data, estimates that total welfare is reduced dramatically when reopening is not coordinated among states and regions. from Phys.org - latest science and technology news stories https://ift.tt/3hUan4W

We are changing the Earth system at a unprecedented speed without knowing the consequences in detail. Increasingly detailed, physics-based models are improving steadily, but an in-depth understanding of persisting uncertainties is still lacking. The two main challenges have been to obtain the necessary amount of detail in the models and to accurately predict how anthropogenic carbon dioxide disturbs the climate's intrinsic, natural variability. A path to surmounting both of these obstacles are now laid out in a comprehensive review published in Reviews of Modern Physics by Michael Ghil and Valerio Lucarini from the EU Horizon 2020 climate science project TiPES. from Phys.org - latest science and technology news stories https://ift.tt/2P8gshM

T lymphocyte cells develop in the thymus. They are essential for fighting infections and preventing cancer. The thymus is located just above the heart. It is large in children and gradually reduces in size with age. In the thymus, T lymphocytes develop from progenitor cells, which originate in the bone marrow and travel to the thymus through the bloodstream. This is a continuous process in which cells enter the thymus, proliferate and develop into T lymphocytes. In the end, these cells leave the thymus to scout and defend the body. from Phys.org - latest science and technology news stories https://ift.tt/3fkvcEO

The primary cause of climate change is atmospheric CO2, and levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become a serious environmental problem. In this work, published in Nature Communications, researchers dealt with both problems at one stroke, by developing nano solid acids that transform CO2 directly to fuel (dimethyl ether) and plastic waste to chemicals (hydrocarbons). from Phys.org - latest science and technology news stories https://ift.tt/30ebYfF

Type III radio bursts from the sun are signatures of energetic (∼1–100 keV) electrons, accelerated at the reconnection sites, propagating upward through the corona into the interplanetary medium along open magnetic field lines. The emission mechanism of the bursts is widely believed to be due to coherent plasma processes. The bursts are observed typically in the frequency range ≈1GHz–10kHz, which corresponds to radial distance range between the low—upper corona; this implies that type III bursts can be used to trace the coronal magnetic field over the distance range. from Phys.org - latest science and technology news stories https://ift.tt/39CB2jx

Desert conditions are harsh, and mosses often spend much of the year in a dormant condition, desiccated and brown, until rain comes. Researchers discovered two species of moss that found a hiding place under translucent milky quartz where they can stay moist and green and continue to photosynthesize and grow while other mosses on the soil surface go dormant. This is the first green plant known to seek such refuge. from Latest Science News -- ScienceDaily https://ift.tt/2OYuORI

Bacteriophages, or phages, may play a significant role in treating complex bacterial infections in prosthetic joints, according to new research. The findings suggest phage therapy could provide a potential treatment for managing such infections, including those involving antibiotic-resistant microbes. from Latest Science News -- ScienceDaily https://ift.tt/2BwhGQz

The thalamus is a 'Grand Central Station' for sensory information coming to our brains. Almost every sight, sound, taste and touch travels to our brain's cortex via the thalamus. Researchers now report that the somatosensory part of the thalamic reticular nucleus is divided into two functionally distinct sub-circuits that have their own types of genetically defined neurons that are topographically segregated, physiologically distinct and connect reciprocally with independent thalamocortical nuclei via dynamically divergent synapses. from Latest Science News -- ScienceDaily https://ift.tt/2P01Voh
