How Far Would You Have to Tunnel Underground to Lose 20 Pounds?
In What If? 2, Randall Munroe explains that evading gravity can reduce your mass—but let’s do the math to see how far you have to go......»»
Seismic waves used to track LA"s groundwater recharge after record wet winter
Record-setting storms in 2023 filled California's major reservoirs to the brim, providing some relief in a decades-long drought, but how much of that record rain trickled underground?.....»»
New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
"Sour Patch" adults: 1 in 8 grown-ups love extreme tartness, study shows
For most people, biting into a lemon would leave them puckered up and desperate to lose that sour flavor, but a new study by Penn State researchers revealed that roughly one in eight adults like intensely sour sensations. The cross-cultural study, re.....»»
The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the.....»»
What do we lose when our old suburbs disappear?
I live on the edge of Parramatta, Australia's fastest-growing city, on the kind of old-fashioned suburban street that has 1950s fibros constructed in the post-war housing boom, double-story brick homes with Greek columns that aspirational migrants bu.....»»
Advances in understanding the evolution of stomach loss in agastric fishes
Living beings can evolve to lose biological structures due to potential survival benefits from such losses. For example, certain groups of ray-finned fishes show such regressive evolution—medakas, minnows, puffera, and wrasses do not have a stomach.....»»
It’s cutting calories—not intermittent fasting—that drops weight, study suggests
The study is small and imperfect but offers more data on how time-restricted diets work. Enlarge (credit: Getty | David Jennings) Intermittent fasting, aka time-restricted eating, can help people lose weight—but the r.....»»
Rewild the soil: The largest urban rewilding project is going underground
The largest urban rewilding project in the U.K. is happening on an old golf course......»»
Dense network of seismometers reveals how the underground ruptures
The idea that earthquakes release stress by a single strong quake along a single fault plane may need to be corrected. A recent study by researchers from the Karlsruhe Institute of Technology (KIT) with the participation of the GFZ German Research Ce.....»»
On-demand nutrient production system for long-duration space missions
When astronauts embark on long space missions, they'll need to grow their own food because pre-packaged meals from Earth lose their nutritional value over time. The BioNutrients project at Ames Research Center's Space Biosciences Division has solved.....»»
Anthropocene activities dramatically alter deep underground fluid flux, researchers find
Much of Earth's water is hidden hundreds of meters beneath our feet, among soil particles and deep within rock pores and fractures......»»
Type of plastic film on high tunnels can filter sunlight, influence plant growth
High-tunnel growing systems, sometimes called hoop houses, have gained popularity for their ability to enhance growth conditions and extend the growing season of horticultural crops. Now, a team led by Penn State researchers has demonstrated that gro.....»»
Orbital eccentricity may have led to young underground ocean on Saturn"s moon Mimas
Saturn's moon Mimas could have grown a huge underground ocean as its orbital eccentricity decreased to its present value and caused its icy shell to melt and thin......»»
The cicadas are coming: An entomologist"s take on a once-in-200-years event
Get ready. Billions of trillions of singing, winged insects with big red eyes are about to emerge from more than a decade of sleep underground......»»
ProtoDUNE"s argon filling underway, a significant step toward next era of neutrino research
CERN's Neutrino Platform houses a prototype of the Deep Underground Neutrino Experiment (DUNE) known as ProtoDUNE, which is designed to test and validate the technologies that will be applied to the construction of the DUNE experiment in the United S.....»»
Examining the blowtorch effect of satellite reentry through video
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgar.....»»
Wind energy and bat conservation: Scientists call for the global application of measures to reduce fatalities
The construction of wind turbines as a cornerstone for the production of climate-friendly electricity is rapidly increasing all over the world—and everywhere this results in major challenges for bats, which die directly at the turbines or lose valu.....»»
Why is it so hard to drill off Earth?
Humans have been digging underground for millennia—on the Earth. It's where we extract some of our most valuable resources that have moved society forward. For example, there wouldn't have been a Bronze Age without tin and copper—both of which ar.....»»

An inside look at how plants and mycorrhizal fungi cooperate
For millions of years, underground fungi have lived in symbiosis with plant roots. Plants provide photosynthesized carbon, while fungi deliver water and nutrients. In order to do so, these organisms share space at the cellular scale: fungi stretch a.....»»
