Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran

What science tells us about the algae bloom in the Lincoln Memorial Reflecting Pool

Algal blooms in the Lincoln Memorial Reflecting Pool in Washington, D.C., have long been a visible public nuisance. When the pool turned green again on June 15, less than two weeks after President Donald Trump's US$14 million renovation, it sparked outrage, a rush to use chemical

What DC's algal bloom reveals about a growing water threat

When bright green water appeared in the newly renovated Lincoln Memorial Reflecting Pool, it drew national attention and sparked political finger-pointing. The culprit: cyanobacteria—sometimes called blue-green algae—a type of bacteria that can produce toxins harmful to people, p

Reflecting pool algae: the science Trump needs to know – podcast

The Lincoln Memorial reflecting pool in Washington DC has hardly been out of the news since April when President Trump vowed to have it renovated, and painted ‘American flag blue’ by 4 July. Despite the pool being stripped, cleaned, coated and refilled, within days the algae that

Scientists discover a surprising link between vitamin C and brain health

Could something as simple as vitamin C help support a healthier aging brain? In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker connections in a key brain ne

Scientists discover why some brains resist Alzheimer's

Some brains appear to fight back against Alzheimer's by helping immature brain cells survive damage instead of succumbing to it. Understanding this natural resilience could point researchers toward entirely new ways to protect memory and slow dementia.

Controlling magnetic chirality could help memory pack in more data

Magnetic storage devices, like a computer's hard disk drive, utilize magnets to represent binary data. However, as these devices are downsized, stray magnetic fields generated by individual magnetic components can interact with neighboring elements to cause operational malfunctio

Nanobubbles cleaned up the Lincoln reflecting pool: Here's how they could be used on dying

Ahead of the 250th anniversary of the Declaration of Independence in the U.S., an ozone nanobubble system has been used to keep the Lincoln Memorial Reflecting Pool clear. Months before the celebrations, a massive cleanup of the pool had taken place, but despite this, an algae bl

Incredible new material makes heat programmable

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use lig

A new route to electrically controlled helimagnetic structures

Advanced magnetic memory and spintronic devices rely on the ability to control magnetic states using electricity. Today, such technologies work by manipulating relatively simple magnetic structures found in ferromagnets, where all the magnetic moments point the same way. However,
