Redesigning an elusive bacterial enzyme into an efficient green catalyst
Redesigning an elusive bacterial enzyme into an efficient green catalyst Sadie Harley Scientific Editor Robert Egan Associate Editor Industrial oxidation chemistry is a cornerstone of modern manufacturing, accounting for nearly one-third of all chemical industrial processes. While essential for making pharmaceuticals, dyes, and many specialty chemicals, industrial oxidation typically relies on high-temperature, high-pressure processes involving toxic oxidizing agents. This has motivated...
California professor argues need for 'objective measures' after state drops ACT/SAT requirement
A growing consortium of University of California professors is urging the state university system to bring back standardized testing, warning that the elimination of admissions tests has degraded academic readiness and forced instructors to teach "middle school math" to college undergraduates. More than 1,400 UC faculty members have signed an open letter calling on leadership to reinstate the SAT and ACT mathematics requirements for Science, Technology, Engineering, and Math (STEM) majors....
Bacteria uncover distinct strategy to import rare sugar polymers, crystal structures show
Bacteria uncover distinct strategy to import rare sugar polymers, crystal structures show Sadie Harley Scientific Editor Andrew Zinin Lead Editor Even though sugars are often framed as simple sources of energy, they also serve as structurally complex and functionally diverse molecules that mediate interactions between organisms. Among these, β-1,2-glucans, which are a class of glucose-based polymers, stand out for their varied and sometimes subtle roles. Found across a wide range of...
D&D-seq maps DNA-protein interactions in single cells with multi-omics compatibility
D&D-seq maps DNA-protein interactions in single cells with multi-omics compatibility Sadie Harley Scientific Editor Robert Egan Associate Editor A new technology allows scientists to map, in single cells, the DNA binding sites of transcription factors and other regulatory proteins that control gene activity, according to a study led by investigators at Weill Cornell Medicine and the New York Genome Center. With key advantages over methods currently in use, the technology is expected to be a...
'Seismic champagne effect' may explain why fires break out long after earthquakes
'Seismic champagne effect' may explain why fires break out long after earthquakes Gaby Clark Scientific Editor Robert Egan Associate Editor Following the devastating urban fire that broke out in Wajima City after Japan's 2024 Noto Peninsula earthquake, investigators struggled to identify a clear ignition source, despite widespread destruction and unusual reports of flames emerging from areas with no visible combustible material. While previous studies have linked earthquakes to secondary...
Empirical assessment of ChatGPT's answering capabilities in natural science and engineering
arXiv:2309.10048v2 Announce Type: replace Abstract: ChatGPT is a powerful language model from OpenAI that is arguably able to comprehend and generate text. ChatGPT is expected to greatly impact society, research, and education. An essential step to understand ChatGPT's expected impact is to study its domain-specific answering capabilities.
Technology used to monitor conservation efforts at Rome's Colosseum to be used at the Ipiranga Museum
Technology used to monitor conservation efforts at Rome's Colosseum to be used at the Ipiranga Museum Sadie Harley Scientific Editor Andrew Zinin Lead Editor The same three-dimensional laser scanning technology used to monitor the Colosseum in Rome will be used in a conservation project at the Ipiranga Museum in São Paulo, Brazil. Beatriz Kuhl, a professor at the University of São Paulo's Faculty of Architecture and Urbanism (FAU-USP), presented the initiative, which is scheduled to begin in...
'Molecular movie' technology reveals a better way to thwart environmental pollutant
'Molecular movie' technology reveals a better way to thwart environmental pollutant Sadie Harley Scientific Editor Robert Egan Associate Editor The latest production from the "molecular movie" imaging technology developed at Oregon State University is a new, inexpensive way of dealing with a common environmental pollutant. Based on short-pulse lasers, the imaging technology allows chemical and biological actions to be measured as they are occurring, one high-speed frame at a time. The...
Actually, the SAT Was Necessary After All
Zvezdelina Stankova has taught mathematics at UC Berkeley for nearly three decades. But in 2023, while teaching introductory calculus for the first time since the beginning of the coronavirus pandemic, she noticed that something was quite wrong. The bottom 25 percent of students were not just struggling with the coursework, Stankova told me; “people were in freefall.”
The Betrayal of Black Patriots
Photographs by Nate Langston PalmerDaniel “Chappie” James Jr. became commander of the Wheelus Air Base, near Tripoli, just after rebels under Muammar Qaddafi took control of Libya in a coup in 1969. In the midst of the insurgency, Qaddafi led an effort to break into the U.S. air base, but James managed to close the gate in time to prevent the young rebel from entering. The incident, which James recounted in a 1978 interview, would come to be the stuff of Air Force lore.
