An international research team has for the first time designed realistic photonic time crystals 鈥撯�� exotic materials that exponentially amplify light. The breakthrough opens up exciting possibilities across fields such as communication, imaging and sensing by laying the foundations for faster and more compact lasers, sensors and other optical devices.
Much of modern life depends on the coding of information onto means of delivering it. Researchers at Aalto University鈥檚 Department of Applied Physics found a new way to create tiny hurricanes of light 鈥� known to scientists as vortices 鈥� that can carry large amounts of information via cable.
Scientists from across the globe are calling for experts to show their willingness to tackle emissions challenges in the built environment sector by endorsing a call for more effective collaboration between researchers and policymakers.
In a pioneering longitudinal study, researchers tracked one person鈥檚 brain and behavioural activity for five months using brain scans and data from wearable devices and smartphones. They found that the everyday effects of sleep, exercise, heart rate and mood 鈥� both good and bad 鈥� could linger in our brains for over two weeks.
Researchers have developed a binder material that can replace carbon-intensive cement on soft clay construction sites. It's capable of slashing emissions from binder manufacturing by up to 75%, without compromising the durability of structures in construction.
A new study has found that intelligence, in the form of general cognitive abilities such as perception, thinking and remembering, is more important than hitherto thought at predicting a person鈥檚 ability to complete common tasks with a PC.
We use the word 鈥榣ove鈥� in a bewildering range of contexts 鈥� from sexual adoration to parental love or the love of nature. Now, more comprehensive imaging of the brain may shed light on why we use the same word for such a diverse collection of human experiences.
Hitherto a mystery, the thermal energy loss of qubits can be explained with a surprisingly simple experimental setup, according to research from Aalto University.
Over the next three years, European researchers aim to construct passive ventilation systems not from concrete or steel, but from a wood-based foam.
Researchers at Finland鈥檚 Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order 鈥� it also provides a useful tool for a wide range of research, such as work on complex materials, phase transitions and condensed matter physics.
In a major multidisciplinary collaboration effort across Finland, Sweden, Norway and Denmark, researchers have published a pioneering study on the spread of infections across Nordic borders from spring until the end of 2020. The report sheds light on the efficacy of cross-border travel restrictions, helping us better understand which measures actually make a difference.
If we can standardise a comprehensive metric for well-being, we make it a more serious alternative for measuring progress, says Aalto University Professor Frank Martela.
The trend towards hyperscale cloud infrastructures is creating powerful global gatekeepers of computational capability. We must understand the geopolitical implications.
Researchers have developed a novel cell culturing technique that reveals the hidden biomechanics of breast cancer 鈥� the end goal, 鈥渞adical improvement鈥� in the laborious process of screening chemotherapeutics.
New research suggests that people perform better if they think they have an AI assistant 鈥� even when they鈥檝e been told it鈥檚 unreliable and won鈥檛 help them.
Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give machines ethereal fingers.
