Journalists and social media users are key drivers behind product recall decisions, says researcher
Canada saw a record 2,330 product recalls in 2023—more than six per day and the highest since the federal government started releasing the data in 2011. A product recall occurs when a manufacturer takes action to remove consumer goods with safety d.....»»
Engineers design lookalike drug nanocarrier to evade lung"s lines of defense
A drug-carrying molecule designed to cure disease by slipping past the lung's natural defenses offers new hope for people with chronic or deadly respiratory diseases, say its creators, researchers in assistant professor Liheng Cai's Soft Biomatter La.....»»
How particles of light may be producing drops of the perfect liquid
The world's largest and most powerful particle accelerator may be producing the world's tiniest droplets of liquid, right under scientists' noses. Researchers are digging into this subatomic enigma......»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Repurposing pencil lead as an optical material using plasma
Optical materials are essential in many modern applications, but controlling the way a material reflects light on its surface is costly and difficult. Now, in a recent study, researchers from Japan found a simple and low-cost way of tuning the reflec.....»»
Printed electronics material can store 1,000 times more charge than current forms
Imagine knowing your milk has gone bad without having to open your fridge. A technology called printed electronics could one day make innovations like this possible......»»
Researchers discover smarter way to recycle polyurethane
Researchers at Aarhus University have found a better method to recycle polyurethane foam from items like mattresses. This is great news for the budding industry that aims to chemically recover the original components of the material—making their pr.....»»
Researchers develop a test bed for separating valuable material on the moon
It's often better to flesh out technologies fully on Earth's surface before they're used in space. That is doubly true if that technology is part of the critical infrastructure keeping astronauts alive on the moon......»»
Apple accused of using privacy to excuse ignoring child abuse material on iCloud
A proposed class action suit claims that Apple is hiding behind claims of privacy in order to avoid stopping the storage of child sexual abuse material on iCloud, and alleged grooming over iMessage.Apple cancelled its major CSAM proposals but introdu.....»»
Chromatin structure found to play a key role in canine social behavior evolution
A study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation......»»
“Slapped cheek” virus is surging across Europe and US, CDC warns

Rapid removal of emerging endocrine disruptors in wastewater using high-performance single-atom catalysts
Bisphenols are widely used as the main raw material for plastics such as receipts, water bottles, water containers, and vinyl due to their heat-resistant and mechanochemical properties. Among bisphenols, bisphenol A (BPA), which we often refer to as.....»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
