Why did you choose your job? Or where you live? Scientists at the University of Warwick have discovered that it was probably to keep your options as open as possible - and the more we co-operate together, the more opportunities are available to us.
Life depends on double-stranded DNA unwinding and separating into single strands that can be copied for cell division. St. Jude scientists have determined at atomic resolution the structure of machinery that drives the process.
Breast ultrasound elastography is an emerging imaging technique used by doctors to help diagnose breast cancer by evaluating a lesion's stiffness in a non-invasive way. USC researchers identified the critical role machine learning can play in making this technique more efficient and accurate in diagnosis.
A computer model shows that a starfish-like animal can coordinate rhythmic motion based on body structure without the brain telling them to do so. This provides insights useful for physiology and robotics.
X-ray imaging shows that nanostructured silica acts as a protective vehicle to deliver intact antigen to the intestine so that it can trigger an immune response. The material can give rise to a polyvaccine against six diseases.
An article published in the journal PLOS Pathogens reports a realistic computational model for the structure and mechanism of replication of prions, infectious agents responsible for mad cow disease and other neurodegenerative disorders of human and animals.
Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line. In a new study published July 12, 2019 in the journal Science, the researchers describe their latest advance, called sheath-run artificial muscles, or SRAMs.
This research is a fundamental discovery of how to engineer proteins onto non-biological surfaces. Artificial proteins engineered from scratch have been assembled into nanorod arrays, designer filaments and honeycomb lattices on the surface of mica, demonstrating control over the way proteins interact with surfaces to form complex structures previously seen only in natural protein systems. This study provides a foundation for understanding how protein-crystal interactions can be systematically programmed and sets the stage for designing novel protein-inorganic hybrid materials.
Mussels are notorious maritime stowaways known for damaging the hulls of boats, but these same adhesive properties have widespread engineering applications, scientists in China and the United states write in review published July 10 in the journal Matter. They suggest that the chemistry of mussel threads is inspiring engineering innovations that address a wide range of problems, from cleaning up oil spills to treating contaminated water.
A bioengineering group from the University of Pittsburgh is bringing the worlds of computational modeling and experimentation closer together by developing a methodology to help analyze the wealth of imaging data provided by advancements in imaging tools and automated microscopes. They recently published a paper in PLOS ONE that shows how using approximate Bayesian computation (ABC) can help infer useful quantitative information for experimental design.
