In a recent study, researchers in materials science at Tampere University challenged conventional composite filler shapes by introducing a different approach in which each particle's 3D geometry is designed first, then printed to specification. The research enables decisions to be made on the shape of the filler, not only its... Read more

Researchers have demonstrated a new password authentication technique for use in virtual reality (VR) settings, which allows users to choose directions rather than numbers. The approach supports the same number of possible combinations as a six-digit numeric password, but is much easier for users to remember.... Read more

The relentless march of Moore's law is slowing as electronic circuits hit fundamental limits in speed and energy efficiency. The solution, many researchers believe, lies in photonics, using light instead of electrons to process and transmit information. But today's photonic chips rely on the same rigid, inorganic semiconductors that dominate... Read more

Drones have become a crucial element in modern security and defense. The ability to manipulate the signals reflected from drones—so that, for example, it is possible to fly close to a radar without being detected—is therefore not only exciting science but is also of commercial and security interest....

When a process needs a burst of heat, a steady supply may not be enough. Storing thermal energy and delivering it quickly are challenges for applications such as sterilization, cleaning or starting up distillation systems. To solve the problem, Rice University engineers turned to laser physics. By applying optics principles... Read more

A special white paint developed at the University of South Florida could offer a new way to cool buildings, reduce energy consumption and lessen reliance on air conditioning. Created in the lab of Distinguished University Professor Yogi Goswami, the innovative self-cooling paint is applied to roofs and reflects up to... Read more

Engineers can 3D-print high-performance titanium parts for aircraft, medical implants and advanced machinery, but finding the right printing settings can still require costly and time-consuming trial and error. A new study shows how artificial intelligence could help narrow that search before production testing begins.... Read more

What happens when additive manufacturing meets target fabrication engineering? An impossibly small, submillimeter-scale cone that can be manufactured 10 times faster than before, enabling new target configurations for experiments at Lawrence Livermore National Laboratory (LLNL)'s National Ignition Facility (NIF)....

The NFL has given Carnegie Mellon University researchers access to official film and on-field data to develop new technologies that can enhance the way coaches, players and fans annotate, analyze and understand games.... Read more

Scientists at the Brazilian Center for Research in Energy and Materials (CNPEM) in Campinas, São Paulo state, developed an instrument for the Sirius particle accelerator that can observe the interior of solar cells on a nanoscale while they are operating. Rather than analyzing isolated components in a laboratory setting, this... Read more

According to projections, the volume of digital data created, captured, copied and consumed worldwide will reach 175 zettabytes (ZB) in 2026. This is equivalent to the storage capacity of billions of hard drives, such as those found in our laptops. With the rise of artificial intelligence, this global 'datasphere' continues... Read more

Vitamin B12 is essential for the body's proper functioning and is found in foods of animal origin. It is produced by certain bacteria that, in addition to being found in nature, are cultivated at industrial facilities for commercial use, primarily by the food and pharmaceutical industries. It is beneficial when... Read more

For decades, people using 3D printers have faced a tough decision: print quickly, print parts with fine features or print materials that meet performance requirements. Light-based 3D printers are fast and precise but limited in what materials they can use. Extrusion-based techniques can handle a wider range of functional materials... Read more

The muscles of the human ear reveal what and how we feel. This is the finding of Dr. Farah Corona-Strauss and Sophie Bonnaire, researchers at the Systems Neuroscience & Neurotechnology Unit in Saarbrücken and Homburg. Their research shows that activity in our ear muscles indicates not only who we are... Read more

Making more efficient, longer-lasting lithium-ion batteries has been a challenge for researchers because adding more mass to the batteries restricts how fast electricity and lithium ions can move. To overcome this challenge, a research team has added graphene mesosponge to batteries to improve their performance during fast discharge. Their results... Read more
