Two meteorites are providing a detailed look into outer space

If you’ve ever seen a shooting star, you might have actually seen a meteor on its way to Earth. Those that land here are called meteorites and can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Today, scientists report some of the most detailed analyses yet of the organic material of two...

Running extra: ‘Across-the-board’ good-air quality again, means what, exactly?

We humans. We tend to make mistakes. It’s in our nature to do so. It’s written in our DNA. Furthermore, when we err, as long as the inaccuracy was an innocent one and with no real harm being done, we deserve to be forgiven and then vow to do our absolute darnedest to see to it that the identical misstep not be made again. But just as mistakes can...

Weeding the Knots

Heart-shaped claws reveal their care – gnarled fingers buried deep in soil and brick and clay. A ghostly forest, spreading shadows long across naïve and native hosts. Drawing blood from loam and stone, tiny fragments spread their message thick and fast until a gentle, soapy rain descends unknotting weeds with glossy hands – a...

Campaign underway to discourage diesel-engine tampering

A nationwide outreach and education campaign is underway to discourage tampering with diesel engines, as well as to educate lawmakers about the proposed state legislative policies and practices that may actually encourage it, thanks to the Diesel Technology Forum (DTF). Diesel engines are highly coveted tools of work that power key sectors of our economy...

Trains in the automotive age: Why shrinking the rail physical plant since 1916 peak, was wrong

A family friend who dropped by for a visit the other day asked what I thought of the electric-car craze. Truth be told, this was totally unexpected. That I was queried, and that I was prompted to give a response, I made sure I spoke candidly stating exactly how I felt about it, giving what I was about to say nary a second thought as to how my answer...

Energy-tied carbon emissions drop 25-38% below 2005 levels by 2030, EIA projects. Ongoing progress in said emissions-reductions to 2050 projected

U.S. energy-related CO2 emissions drop 25% to 38% below what they were in 2005 by 2030, according to projections from the U.S. Energy Information Administration’s (EIA) Annual Energy Outlook 2023 (AEO2023). By the end of the projection period, 2050, U.S. energy-related CO2emissions are 17% lower in this year’s Reference case compared with last year,...

Astrophysicists show how to “weigh” galaxy clusters with artificial intelligence

Scholars from the Institute for Advanced Study have used a machine learning algorithm known as “symbolic regression” to generate new equations that help solve a fundamental problem in astrophysics: inferring the mass of galaxy clusters. Galaxy clusters are the most massive objects in the Universe: a single cluster contains anything from a hundred to...

Removal of both ovaries in younger women associated with increased risk of Parkinson’s

Surgical removal of both ovaries is associated with an increased risk of Parkinson’s disease and parkinsonism in women younger than 43, Mayo Clinic researchers report in JAMA Network Open. Using health record data from the Rochester Epidemiology Project, the study included 2,750 women who had undergone surgery to remove both ovaries, a procedure called...

Deceptive daisy’s ability to create fake flies explained

A male fly approaches a flower, lands on top of what he thinks is a female fly, and jiggles around. He’s trying to mate, but it isn’t quite working. He has another go. Eventually he gives up and buzzes off, unsuccessful. The plant, meanwhile, has got what it wanted: pollen. A South African daisy, Gorteria diffusa, is the only daisy known to make such...

AI predicts genetics of cancerous brain tumors in under 90 seconds

Using artificial intelligence, researchers have discovered how to screen for genetic mutations in cancerous brain tumors in under 90 seconds — and possibly streamline the diagnosis and treatment of gliomas, a study suggests. A team of neurosurgeons and engineers at Michigan Medicine, in collaboration with investigators from New York University, University...
