Jurassic World, the fourth installment in the successful film series, in theaters June 12, will take viewers back to a world in which dinosaurs have been revived.
While dinosaur fossils are too old and… read more
In a clinical study, Spanish researchers have used a Microsoft Kinect to help stroke patients increase their ability to use a paralyzed arm.
Stroke patients with “hemiparesis” —- reduced muscle strength on one side of the body — often under-use their affected limbs even though they still have some motor function. A long period of non-use of the affected “paretic” limb can lead to further loss of… read more
New technology called called VirScan developed by Howard Hughes Medical Institute (HHMI) researchers makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person’s blood.
With VirScan, scientists can run a single test to determine which viruses have infected an individual, rather than limiting their analysis to particular viruses. That unbiased approach could uncover unexpected… read more
Researchers at the Georgia Institute of Technology have discovered an new process for assembling DNA nanostructures in a water-free solvent, which may allow for fabricating more complex nanoscale structures — especially, nanoelectronic chips based on DNA.
Scientists have been using DNA to construct sophisticated new structures from nanoparticles (such as a recent development at Brookhaven National Labs reported by KurzweilAI May 26), but the use… read more
Team IHMC Robotics of Pensacola, Fla., with its Running Man (Atlas) robot came in at second place ($1 million prize), followed by Tartan Rescue of Pittsburgh with its CHIMP robot ($500,000 prize).… read more
Soft matter encompasses a broad swath of materials, including liquids, polymers, gels, foam and — most importantly — biomolecules. At the heart of soft materials, governing their overall properties and capabilities, are the interactions of nano-sized components.
Observing the dynamics behind these interactions is critical to understanding key biological processes, such as protein crystallization and metabolism, and could help accelerate the development of important new technologies, such as artificial… read more
Researchers at three universities have developed a new way of making tough — but soft and wet — biocompatible hydrogel materials into complex and intricately patterned shapes. The process might lead to scaffolds for repair or replacement of load-bearing tissues, such as cartilage. It could also allow for tough but flexible actuators for future robots, the researchers say.
The new process is described in a paper in the… read more
A team of Massachusetts General Hospital (MGH) investigators has made the first steps towards developing bioartificial replacement limbs suitable for transplantation.
In a Biomaterials journal report, the researchers describe using an experimental approach previously used to build bioartificial organs to engineer rat forelimbs with functioning vascular and muscle tissue. They also provided evidence that the same approach could be applied to the limbs of primates.
“The… read more
James Boysen, a 55-year-old software developer from Austin, Texas has become the first patient to receive a scalp and skull transplant while receiving kidney and pancreas transplants.
More than 50 health care professionals from Houston Methodist Hospital and The University of Texas MD Anderson Cancer Center assisted with or supported the double surgery over a period of more than 24 hours.
“This was a… read more
An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria — the small worms whose extraordinary power to regrow body parts has made them a research model in human regenerative medicine.
The discovery by Tufts University biologists presents the first model of regeneration discovered by a non-human intelligence and the first comprehensive model of planarian regeneration, which had eluded human scientists for more than… read more
Stanford University engineers have developed a new design algorithm that can automate the process of designing optical interconnects, which could lead to faster, more energy-efficient computers that use light rather than electricity for internal data transport.
Light can transmit more data while consuming far less power than electricity. According to a study by David Miller, the MIT W.M. Keck Foundation Professor of Electrical Engineering, up to 80… read more
The way your brain responds to certain words could be used to replace passwords, according to a study by researchers from Binghamton University, published in academic journal Neurocomputing.
The psychologists recorded volunteers’ EEG signals from volunteers reading a list of acronyms, focusing on the part of the brain associated with reading and recognizing words.
Participants’ “event-related potential” signals reacted differently to each acronym, enough that a computer… read more
A new open-access study shows that social and sensory overstimulation drives autistic behaviors and supports the unconventional view that the autistic brain is actually hyper-functional. The research offers new hope, with therapeutic emphasis on paced and non-surprising environments tailored to the individual’s sensitivity.
For decades, autism has been viewed as a form of mental retardation, a brain disease that destroys children’s ability to learn, feel and empathize, thus leaving… read more
University of Bristol researchers have developed a new augmented-reality display that allows audiences to better appreciate digital musical performances
The research team from the University’s Bristol Interaction and Graphics (BIG) has been investigating how to improve the audiences experience during performances with digital musical instruments, which are played by manipulating buttons, mic, and various other controls.
Overrturning decades of textbook teaching, researchers at the University of Virginia School of Medicine have discovered that the brain is directly connected to the immune system by vessels previously thought not to exist.
The finding could have significant implications for the study and treatment of neurological diseases ranging from autism to Alzheimer’s disease to multiple sclerosis.
“It changes entirely the way we perceive the neuro-immune interaction. We always… read more
