Overcoming challenges in electron transport through graphene nanostructures
Nothing in the world is perfect. This is also true in materials research. In computer simulations, one often represents a system in a highly idealized way; for example, one calculates the properties that an absolutely perfect crystal would have. In p.....»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
From pollution to power: Merging wastewater treatment and energy generation with capacitive MFC innovations
Imagine standing on the edge of a new frontier, where waste—something we often view as a problem—becomes the solution. We live in a world that needs innovation, where environmental challenges demand a sustainable approach, and where we need techn.....»»
Flaming Audi EV on dealership lift challenges firefighters
Firefighters were able to lower the EV from the lift and push it outside so the flames could be fully extinguished......»»
Methane is pitched as a climate villain—could changing how we think about it make it a savior?
Surging methane emissions put our ability to meet Paris agreement climate targets in jeopardy. But a timely new book presents the scientific, policy and technological challenges and solutions for achieving rapid climate gains by addressing this once.....»»
Research highlights the unseen challenges, adaptations of adult daughters during COVID upheaval for families
A Baylor University study has shed light on the often-overlooked experiences of women doing "daughtering" in families, particularly during the COVID-19 pandemic, which created immense challenges in their relationships with parents and other family me.....»»
Simulated construction of plant-based fish meat with composite structure via 3D printing
To date, about 90% of fish resources worldwide have already reached their sustainable fishery limit. Meanwhile, intensive farming and aquaculture contribute to significant environmental pollution and degradation. To address both the challenges of lim.....»»
Cleaning the ocean has a price — and layers of complications
Pulling plastic from the ocean and recycling that into auto parts is the plan. The challenges are immense, but worth it......»»
