Why some feces float and others sink
A team of researchers at the Mayo Clinic has solved the mystery of why some people find their bowel movements floating while others find theirs sinking to the bottom of the toilet bowl. In their paper published in the journal Scientific Reports, the.....»»
DNA in the feces of snow leopards shows alpine cats eat plants
Cats may not know Scarborough Fair, but felids such as alpine cats—both in the wild and in captivity—do eat plants despite their classification as carnivores. In particular, Panthera uncia—or snow leopards—seem to have a preference for a spec.....»»
Tropical forests adjust strategies to thrive even when soils are nutrient poor, large field experiment shows
Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recoveri.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
New method can create aquatic levitation at much lower temperature, has implications for cooling nuclear reactors
Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface......»»
Academic calls for upgrade to sewage systems to protect health
The risk to public health from human feces in our rivers and seas will increase without action to create a wastewater system fit for the future, according to a Leeds academic......»»
West Coast seabird study shows how they might one day share the air with wind turbines
One day, wind turbines may float off the coasts of California and southern Oregon, providing clean, renewable energy to millions of homes. But before construction can start, researchers are studying how to minimize the potential wind farms' impact on.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
Sink to source: Does what we put into our plumbing end up back in the water supply?
When you see an advertisement for a detergent promising to brighten your clothes, something called a fluorescent whitening compound, or optical brightener, is probably involved. Such material absorbs UV light and emits visible blue light via fluoresc.....»»
Researchers reveal oceanic black carbon sink effect driven by seawater microdroplets
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic bla.....»»
Mexico City’s Metro System Is Sinking Fast. Yours Could Be Next
Subsidence is causing parts of Mexico City to sink, and it’s happening at an uneven rate. That’s bad news for its sprawling public transportation system......»»
EJBCA: Open-source public key infrastructure (PKI), certificate authority (CA)
EJBCA is open-source PKI and CA software. It can handle almost anything, and someone once called it the kitchen sink of PKI. With its extensive history as one of the longest-standing CA software projects, EJBCA offers proven robustness, reliability,.....»»
Africa"s carbon sink capacity is shrinking
The population of Africa, the second-largest continent in the world, currently sits at about 1.4 billion, but is set to exceed 2 billion by 2040. This means greater swaths of land than ever before are being used for agriculture, and livestock numbers.....»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
Spatial Personas adds 3D calling to FaceTime on Apple Vision Pro
FaceTime is set to become more immersive for Apple Vision Pro users, with Apple testing out Spatial Personas that make callers float in front of you.Spatial Personas [Apple/Inverse]Spatial Personas [Apple/Inverse]Spatial Personas [Apple/Inverse]Like.....»»
New model integrates soil microbes, large perennial grasses
Of all the carbon stored in ecosystems around the world, about half can be found in soils. Depending on climate, vegetation, and management, soils can be either a carbon source or a sink......»»
Satellite data unlocks drought impact on southwest China"s carbon cycle
Over the past four decades, Southwest China has been a major carbon sink, significantly mitigating anthropogenic CO2 emissions. However, recent severe droughts, especially from 2009 to 2013 and in 2022, have drastically reduced its carbon absorption.....»»
Research explains why eating feces may be vital for birds" survival
We all know that the early bird gets the worm, but new research shows they turn to something far more nutritious for their breakfast. Feces—either their own, or from other birds—provides them with essential nutrients and energy and helps them ada.....»»
Vehicle subscriptions work to prove worth in a sink or swim market
The few startups and programs still in operation are trying to find the right pricing and logistical models to survive......»»
Watch this astronaut’s ‘space waltz’ on the ISS
Private astronaut Marcus Wandt described the waltz as a training routine to help him float more skillfully in the station's microgravity conditions......»»
Perils of pet scat—so much more than just unsightly and smelly, it can spread disease
