1.5°C degrowth scenarios suggest need for new mitigation pathways: Research

The first comprehensive comparison of 'degrowth' scenarios with established pathways to limit climate change highlights the risk of over-reliance on technological innovation to support continued global growth - which is assumed in established global climate modelling. Findings include: Technologically less risky 'degrowth' limits global warming to 1.5C while global GDP declines by 0.5% annually; a...

A beetle's Achilles heel

Susceptibility of their microbial partners to the herbicide may be an underestimated weak spot of insects that could add to their decline.

A comprehensive map of the SARS-CoV-2 genome

MIT researchers have generated what they describe as the most complete gene annotation of the SARS-CoV-2 genome. In their study, they confirmed several protein-coding genes and found that a few others that had been suggested as genes do not code for any proteins.

Americans are increasingly experiencing chronic pain

This study comprehensively documents rising levels of chronic pain among Americans aged 25-84 to show that pain prevalence -- already high at baseline -- increased substantially from 2002-18, with increases evident in all leading pain sits (joint, back, neck, jaw and migraine).

Bioengineering approach for functional muscle regeneration

When trauma, illness, or injury causes significant muscle loss, reconstructive procedures for bioengineering functional skeletal muscles can fall short, resulting in permanent impairments. Finding a synergy in the importance of biochemical signals and topographical cues, researchers developed an efficient technique for muscle regeneration and functional restoration in injured rats. They describe...

Bone-deep: Mineral found in human bone can help fight toxic organic compounds

Many industrial processes emit volatile organic compounds (VOCs) that are hazardous to human health. In a new study, scientists from NITech, Japan, tailor the catalytic activity of hydroxyapatite, a mineral contained in human bones, using mechanical stress. This method was inexpensive and resulted in a 100% VOC conversion, potentially opening doors to effective climate control.

Box fan air cleaner greatly reduces virus transmission

Improved ventilation can lower the risk of transmission of the COVID-19 virus, but large numbers of decades-old public school classrooms lack adequate ventilation systems. A systematic modeling study of simple air cleaners using a box fan reported in Physics of Fluids shows these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately.

Coral reef restorations can be optimized to reduce flood risk

A new study sets out guidelines to maximize the benefits of reef restoration, not only for the coral ecosystem, but also to protect local communities from coastal flooding. Researchers simulated waves travelling over different reef profiles at various stages of restoration and found that to reduce the risk of flooding, the upper fore reef and middle reef flat, typically characterized by...

COVID-19 alters gray matter volume in the brain, new study shows

COVID-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study led by researchers at Georgia State University and the Georgia Institute of Technology. The study's findings demonstrate changes to the frontal-temporal network could be used as a biomarker to determine the likely prognosis of...

Dartmouth engineering study shows renewable energy will enhance power grid's resilience

A new Dartmouth Engineering study shows that integrating renewable energy into the American Electric Power System (AEPS) would enhance the grid's resilience, meaning a highly resilient and decarbonized energy system is possible. The researchers' analysis is based upon the incremental incorporation of architectural changes that would be required to integrate renewable energy into AEPS.

Disparities persisted as orthopaedic visits shifted to telemedicine

Like other medical specialties at the start of the COVID-19 pandemic, orthopaedic surgery rapidly pivoted from in-person visits to remote appointments via telemedicine. Analysis of that initial experience finds that some groups of patients faced persistent or worsening disparities as the shift to telemedicine occurred, reports Clinical Orthopaedics and Related Research® (CORR®), a...

Electromagnetic levitation whips nanomaterials into shape

To deliver reliable mechanical and electric properties, nanomaterials must have consistent, predictable shapes and surfaces, as well as scalable production techniques. UC Riverside engineers are solving this problem by vaporizing metals within a magnetic field to direct the reassembly of metal atoms into predictable shapes.
