Report: Student research team develops hybrid rocket engine
In a year defined by obstacles, a University of Illinois at Urbana-Champaign student rocket team persevered. Working together across five time zones, they successfully designed a hybrid rocket engine that uses paraffin and a...
Report: Single-use N95 respirators can be decontaminated and used again
N95 respirators, which are widely worn by health care workers treating patients with COVID-19 and are designed to be used only once, can be decontaminated effectively and used up to three times, according to...
Study: Ocean acidification causing coral ‘osteoporosis’ on iconic reefs
Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which also influence...
Study: Vast stone monuments constructed in Arabia 7,000 years ago
The last decade has seen rapid development in the archaeology of Saudi Arabia. Recent discoveries range from early hominin sites hundreds of thousands of years old to sites just a few hundred years old....
Study: A government program that reduces mortgage defaults
Lower-income households that received mortgages through state affordable mortgage programs were less likely to default or foreclose than similar households that received conventional financing, a national study found.
Researchers examined the outcomes of homeownership programs...
Scientists introduce new theory to calculate emissions liability
A comparison of the results for conventional point source pollution and bottleneck carbon emissions sources shows that oil and natural gas pipelines are far more important than simple point-source emissions calculations would indicate. It...
Study: Importance of rainfall highlighted for tropical animals
Imagine a tropical forest and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys, and ... rain. Indeed, precipitation patterns, along with temperature, dictate where tropical forests are distributed...
Study: Reprogramming immune cells to reduce inflammation
Macrophages are white blood cells that, depending on the signals they get from the immune system, become specialized in either increasing or decreasing inflammation. When macrophages are programmed to be pro-inflammatory, they help to...
Study: Protein ‘chameleon’ colors long-term memory
A chameleonlike protein in neurons can change its mind, and in the process change our brains.
Scientists at Rice University and the University of Texas Health Science Center at Houston (UTHealth) uncovered new clues in...
Study: East Antarctic melting hotspot identified
Ice is melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica due to the continuing influx of warm seawater into the Lützow-Holm Bay.
Hokkaido University scientists have identified an atypical hotspot...
