How woodpeckers turn their entire bodies into hammers
Earth.com reported
Woodpeckers don’t just tap – they strike with astonishing force. Each strike can bring decelerations up to 400 g, a level that would flatten most creatures.
A new study reveals how woodpeckers brace nearly their entire body – head, neck, and abdomen – so the bird becomes, mechanically, a hammer.

Giant cactus plants ‘loosen up’ to bend with the desert wind
Earth.com reported
The saguaro cactus is engineered for endurance in one of North America’s toughest environments. Rising up to 70 feet tall, with arms reaching skyward like desert sculptures, the cactus endures searing heat, fierce monsoon winds, and shifting sands.
But how does the saguaro manage to stay upright? A new study reveals that this giant cactus constantly flexes with subtle vibrations invisible to the naked eye.

Chernobyl Fungus Appears to Have Evolved an Incredible Ability
ScienceAlert reported
The Chernobyl exclusion zone may be off-limits to humans, but ever since the Unit Four reactor at the Chernobyl Nuclear Power Plant exploded nearly 40 years ago, other forms of life have not only moved in but survived, adapted, and appeared to thrive.

Study Finds Pesticide Residue Widespread on Urban Butterfly Plants
Xerces Society reported
A new study published in Environmental Toxicology and Chemistry found nearly ubiquitous pesticide contamination on butterfly host plants across two U.S. cities, Albuquerque, New Mexico, and Sacramento, California. In 20% of the plants tested, pesticide residues were at levels known to kill or otherwise harm butterflies and moths.
Smarter Pest Management: Pollinator Protection for Cities and Campuses
From the Xerces publications library, this fact sheet shares tips and resources for protecting pollinators in urban spaces and developing an integrated pest management approach.

The big bad wolf is really a scaredy cat
Anthropocene Magazine reported
New research finds that wolves are afraid of the super predator in the woods (humans)—and that protecting them doesn’t make them less fearful of us.
While wolves’ reputation as fearsome predators makes them the stuff of old legends and modern polemics, at least one animal will prompt them to turn tail: humans.
That insight from new research runs counter to speculation that wolves protected by conservation laws might become emboldened and attack people unprovoked.

Dolphins may be getting Alzheimer’s from toxic ocean blooms
ScienceDaily reported
Dolphins washing up on Florida’s shores may be victims of the same kind of brain degeneration seen in humans with Alzheimer’s disease. Researchers discovered that cyanobacterial toxins—worsened by climate change and nutrient pollution—accumulate in marine food chains, damaging dolphin brains with misfolded proteins and Alzheimer’s-like pathology

UC Berkeley Botanical Garden houses crucial seed bank to preserve biodiversity
CBS San Francisco reported
Above the main campus at the University of California, Berkeley, nestled in Strawberry Canyon at the Botanical Gardens, you’ll find a critically important bank. It doesn’t store hordes of cash or glittering gold bullion. This bank stores seeds.
“So, we have millions of seeds represented from hundreds of different species from rare and endangered plants and they are all meticulously curated,” explained curator and conservation officer Clare Loughran.

Where to Find Fungi, Once the Rains Begin
Bay Nature reported
The soils beneath our feet teem with fungi. The mycelia-networks of rootlike hyphae that form the actual fungal organism-are interwoven and conjoined with tree roots underground. During the winter months, rain spurs the matrix of mycelia to develop fruiting bodies: mushrooms. These caps emerge from the duff in a great variety of shapes and colors.
Public parks are great places to spot varieties of mushrooms. But beware: most parks in California restrict or outright forbid mushroom collecting; in some parks, the fines can be considerable. Furthermore, those untrained in the proper identification of California’s approximately 300 species should take care, as more than a few are toxic if eaten. However, there are no penalties-and many rewards-for admiring these evanescent beauties in their natural settings. Here is, by county, a list of some sites recommended by local fungophiles for good mushroom viewing.

Hundreds of Joshua trees were scorched during the shutdown
MSN reported
A firefighter with the National Park Service says a fire wiped out more than a thousand Joshua trees amid the government shutdown. Restoration could be limited by a depleted staff, they said.

Bowhead Whales Live Long Lives. Do They Hold the Key to Human Longevity?
Smithsonian Magazine reported
With a lifespan of over 200 years, bowhead whales are remarkably resistant to age-related illnesses like cancer. Now, a new study has uncovered how these 80-ton mammals can survive for so long. The answer could help humans, too.
In a study published this week in the journal Nature, researchers found that the key to the whales’ lifespans is a cold-activated protein called CIRBP. This protein can repair damaged DNA, and bowhead whales have large amounts of it.

What moves the sailing stones of Death Valley?
EarthSky reported
How could rocks – driven by some unseen force – slide across the ground, leaving behind a trail? That’s what happens at Racetrack Playa, a dry lake bed at Death Valley National Park in California. The definitive solution to this long-standing mystery finally came in 2014, from two cousins. Their work showed that the rocks are nudged into motion by melting panels of thin floating ice, driven by light winds, in winter.

Soil treated only with organic fertilizer yields very exciting results
A summary of what Earth.com found out about benefits of organic fertilizer
A study by Kansas State University examined soil from a Kansas cornfield that had not been tilled for 22 years. The study found that soil treated with organic amendments like manure or compost had higher carbon levels and more carbon stored in protected pores and on mineral surfaces compared to soil treated with synthetic fertilizer or no fertilizer. This suggests that organic amendments can increase soil carbon storage and improve soil health, but the effectiveness depends on local conditions and management practices.
