Traveling protein waves reveal how dividing cells set chromosome-splitting spindle size
When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes apart and deposits one set into each new cell. Get the spindle the right size an

Heat-shrinking materials get cleaner production route with lower temperatures and finer pa
Among the many modern technologies that shape life today, functional oxide materials are found in almost everything, from advanced electronics to energy-efficient systems. Functional oxides with high-valent metal ions are a significant topic of interest because of their unusual p

Harvard scientists turn a silicon chip into a DNA writing machine
Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing. The breakthrough could eventually support portable DNA-writing devices and eve
Self-propelled microparticles scrub stubborn biofilms, improving wound care and instrument
Self-propelled microparticles scrub stubborn biofilms, improving wound care and instrument
Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at the University of Illinois Urbana-Champaign report. In two
Q&A: Examining the Global South's call for environmental justice amid expanding technology
Digital technologies—from artificial intelligence to smartphones and data centers—are often described as "clean" innovations. Yet every device depends on minerals, electricity, labor and global supply chains, raising important questions about environmental justice and development
New 3D COF structure could help tune porous materials for batteries and cleanup
A research team synthesized and determined the structure of a borate-linked 3D crystalline covalent organic framework, TCTP-COF, via electron diffraction for the first time. These findings will help scientists determine the structure-property relationships for other 3D COFs and f
Tiny bubbles could revolutionize inkjet printing
Tiny bubbles could revolutionize inkjet printing
Ultra-fine bubbles may offer a cleaner way to perfect inkjet printing for next-generation electronics. By simply changing the number of bubbles in each droplet, researchers were able to dramatically reshape the final printed pattern without leaving behind unwanted chemical residu

‘No matter how bad, it is always fixable’: how Bea Elton cleans up the houses – and lives
She has built an unlikely career in mould, maggots and excrement, cleaning for those who most need it. It can take months building trust with a stranger, before she and her boyfriend go in and transform everything‘There might be a dead bird in the box room. We think it has been t
A new smart coating could improve the cleanup of nuclear wastewater
A new smart coating could improve the cleanup of nuclear wastewater
Scientists in China have developed a smart coating that could make it easier to remove tritium (a radioactive form of hydrogen) from nuclear power plant wastewater.
New technique for building ultra-thin material stacks promises quantum breakthrough
New technique for building ultra-thin material stacks promises quantum breakthrough
Scientists have unveiled a new fabrication technique for the ultra-clean manufacturing of 2D heterostructures—materials just a few atoms thick—that could be used in quantum technology and electronics. Experts from Southampton and Singapore say the method could be used to develop
The secret to hydrogen's quantum behavior lies in symmetry
The secret to hydrogen's quantum behavior lies in symmetry
As interest in clean hydrogen power grows, so does the need for safe storage and transportation materials. One such material, vanadium, is a leading candidate because it readily absorbs hydrogen and allows it to move through its crystal structure. However, hydrogen displays varyi
