Research reveals processes that sculpt submarine canyons (phys.org)

Deep below Monterey Bay lies one of the largest submarine canyons on the west coast of North America. Monterey Canyon has a topography that rivals the Grand Canyon, but its scale and grandeur remain out of sight beneath the waves. Repeated efforts at Monterey Bay Aquarium Research Institute (MBARI) to map and monitor this...

Friend or foe? Study reveals evolution of controversial human gut microbe (phys.org)

Blastocystis is one of the most common microbes found in our guts but its role in human health is poorly understood. Blastocystis infection can lead to diarrhea, nausea, weight loss and fatigue, yet the microbe's presence is also considered by some as a sign of a healthy gut.

Considerable but unsustainable water supply from thawing permafrost on the Tibetan Plateau in a changing climate (phys.org)

In a warming climate, the sustainability of cryospheric meltwater on the Tibetan Plateau has raised concerns because of its importance for the fragile ecosystem in the headwater regions and the dense populations in the downstream. Existing studies mainly focused on glacier melt and snow melt on the Tibetan Plateau, which are...

In search of a lost cemetery, dig begins at a former Native American school in Nebraska (phys.org)

Bodies of dozens of children who died at a Native American boarding school have been lost for decades, a mystery that archeologists aim to unravel as they begin digging in a central Nebraska field that a century ago was part of the sprawling campus.

Houses and high-rises (and nothing in between): Why land zoning hasn't been effective for improving urban density (phys.org)

For almost a century, zoning has been the key tool used by urban planners to influence how our cities grow and change. Our newly published research looked at whether zoning is effective at guiding new urban growth patterns.

Waste disposal in Nigeria is a mess: How Lagos can take the lead in sorting and recycling (phys.org)

Nigeria, like many other Sub-Saharan Africa countries, has a waste management problem. The Nigerian National Municipal Waste Management Policy (2020) gives no estimate but states that, "Nigeria produces a large volume of solid waste out of which less than 20% is collected through a formal system."

Meltwater is hydro-fracking Greenland's ice sheet, destabilizing its internal structure (phys.org)

I'm striding along the steep bank of a raging white-water torrent, and even though the canyon is only about the width of a highway, the river's flow is greater than that of London's Thames. The deafening roar and rumble of the cascading water is incredible—a humbling reminder of the raw power of nature.

Squash bugs are attracted to and eat each other's poop to stock their microbiome (phys.org)

Squash bugs, a common and difficult-to-control agricultural pest, need healthy bacteria in their gut to grow and stay alive. However, they do not acquire any bacteria from their parents when they are first born, leaving them vulnerable until their microbiome can be stocked. Researchers report in the journal Current Biology on...
