Human-Constructed Dams Have Shifted the Earth’s Poles, Scientists Say

Humans have built so many dams around the world that the Earth’s poles have wandered away from the planet’s rotational axis, new research suggests.

Over the last 200 years, humans have constructed nearly 7,000 massive dams, impounding enough water to nudge the Earth’s poles by about three feet (one meter) and cause a 0.83-inch (21-millimeter) drop in global sea levels, according to a new study in Geophysical Research Letters.

This drift is possible because Earth’s solid crust forms a hard shell around a molten layer of gooey magma. This means that whenever a significant amount of mass is redistributed across the planet’s surface, the outermost rock layer wobbles, shifting relative to Earth’s molten interior. When this happens, different areas on the Earth’s surface end up directly over the planet’s rotational axis. As a result, the planet’s poles pass through different surface locations than before, a phenomenon known as true polar wander.

Wireless induction concept demonstrates self-recharging mechanism in batteries

A research team led by the Institute of Materials Science of Barcelona (ICMAB-CSIC) has demonstrated a new induction-based mechanism that enables partial self-recharging in batteries, using a symmetric iron-based configuration as a proof of concept. The study, published in Electrochimica Acta, lays the groundwork for future battery systems that integrate wireless recharging capabilities through induced redox reactions.

Novel molecular mechanisms inform targeted therapies for chronic kidney disease

A recent study led by Paul DeCaen, Ph.D., associate professor of Pharmacology, has identified novel molecular mechanisms by which genetic mutations in the PKD2 gene cause the most common form of polycystic kidney disease, according to findings published in the Proceedings of the National Academy of Sciences.

PKD2 encodes an localized to the primary cilia of cells lining the kidney collecting ducts, a series of tubules and ducts that helps achieve electrolyte and fluid balance in the body. Both inherited and acquired mutations in PKD2 are known to cause (ADPKD), a condition characterized by the growth of fluid-filled cysts in the kidneys that can lead to and other serious complications.

According to the National Institute of Diabetes and Digestive and Kidney Diseases, one in 1000 individuals will develop ADPKD and more than 95% of patients carry disease-causing genetic variants in PKD1 or PKD2. However, there are no available therapies that target these disease-causing variants.

SARS-CoV-2 can cause buildup of Alzheimer’s-related peptides in retina

A new Yale study has found a promising target for treating the brain fog that can follow COVID-19 and offers new insight into a hypothesis about the origin of Alzheimer’s disease.

One of the hallmarks of Alzheimer’s disease is the presence of plaque formed by the buildup of amyloid beta peptides (short chains of amino acids) in and around . Some researchers suspect that amyloid beta, which is structurally similar to , protects the brain against bacteria, viruses, parasites, and . Because the tends to lose its integrity in Alzheimer’s disease patients, the accumulation of amyloid beta might be a signal that pathogens are infiltrating the brain.

In a new study published in Science Advances, Yale researchers investigated whether infection by SARS-CoV-2—the virus that causes COVID-19—can trigger Alzheimer’s disease-like amyloid beta buildup, leading to neurological impairments like .
