Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a nove

A research team has developed a reversible, water-based glue that has good adhesion in the neutral pH range, but can be detached again in strongly acidic or alkaline environments. As the team writes in the journal Angewandte Chemie, the novel adh

A joint research team at KAIST developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room temperature, preventing accidental needle stick injuries a

A scientific team has developed a new polyurethane production technique using CO₂ to create new types of easily recyclable plastics. The study, published in the Journal of the American Chemistry Society (J.A.C.S.), could provide a solu

An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone.

Artificial intelligence (AI) is on the rise. Until now, AI applications generally have "black box" character: How AI arrives at its results remains hidden. Prof. Dr. Jürgen Bajorath, a cheminformatics scientist at the University of Bonn, and his te

Ammonia, a main component of many fertilizers, could play a key role in a carbon-free fuel system as a convenient way to transport and store clean hydrogen. The chemical, made of hydrogen and nitrogen (NH₃), can also itself be burned as a zero-

Intratumoral therapy -- in which cancer drugs are injected directly into tumors -- is a promising treatment option for solid cancers but has shown limited success in clinical trials due to an inability to precisely deliver the drug and because most immuno

The production of ammonia for fertilisers -- which has one of the largest carbon footprints among industrial processes -- will soon be possible on farms using low-cost, low-energy and environmentally friendly technology.

The risk of hearing loss does not come just from loud machinery or other obvious noise. It can also affect people in public environments like theaters and concert halls. Absorbing this excess sound to make public environments safer for hearing and using t

A coronavirus uses protein "spikes" to grab and infect cells. Despite their name, those spikes aren't stiff and pointy. They're shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender s

Distributed cloud storage is a hot topic for security researchers around the globe pursuing secure data storage, and a team in China is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage s
