Though vapes have been heralded as a 'safer' way to consume either nicotine or cannabis, they present their own suite of risks that are being revealed through increasing regulation. Now, scientists have discovered that nano-sized toxic metal particles can be present in cannabis vaping liquids even before any heating occurs, and the effect is worse in illicit products.

Once thrown away, disposable diapers and sanitary pads can take hundreds of years to decompose, because they contain plastics and other synthetic polymers. But now, researchers are replacing these materials with components made from protein biomass that is often discarded. They are sustainable and biodegradable, and they could potentially allow future diapers and pads to be flushed down a toilet or used as fertilizer.

At first glance, Rabih Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, these tiny machines could be used as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.

Water pollution from dyes used in textile, food, cosmetic and other manufacturing is a major ecological concern with industry and scientists seeking biocompatible and more sustainable alternatives to protect the environment. A new study has discovered a novel way to degrade and potentially remove toxic organic chemicals including azo dyes from wastewater, using a chemical photocatalysis process powered by ultraviolet light.

In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.

Researchers have made very fast and very precise images of excitons -- in fact, accurate to one quadrillionth of a second and one billionth of a meter. This understanding is essential for developing more efficient materials with organic semiconductors.

Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

In a first for the condensate field, researchers have figured out how nucleolar sub-structures are assembled. This organization gives rise to unique pH profiles within nucleoli, which they measured and compared with the pH of nearby non-nucleolar condensates including nuclear speckles and Cajal bodies.

Researchers have created a DNA origami platform called DoriVac, whose core component is a self-assembling square block-shaped nanostructure. DoriVac vaccines enabled tumor-bearing mice to better control the growth of tumors and to survive significantly longer than control mice.

Automated insulin dosing systems combine low-cost blood-glucose monitors with insulin pumps that use precision dosing to continuously regulate blood-sugar and hold it steady. Synthetic biologists have found a way to piggyback on the technology and make it universally applicable for the precision dosing of virtually any drug.

A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.

Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.

Mechanical engineers have devised a diagnostic platform that uses sound waves to spin an individual drop of water up to 6000 revolutions per minute. These speeds separate tiny biological particles within samples placed in a very light disc sitting on top of the spinning drop. The technique could allow new point-of-care applications ranging from precision bioassays to cancer diagnosis. The technique requires less time and sample volume while inflicting less damage to delicate exosomes.
