A study by Professor Francis Green found no evidence to suggest that successive generations of workers have higher expectations from their jobs, leading to disappointment. The investigation suggests a general trend of falling well-being among British and German workers, but fails to explain the decline in Germany.
Researchers at University of Pittsburgh successfully trained a monkey to feed itself using a child-sized robotic arm controlled by its own brain signals. The breakthrough technology uses tiny electrodes and specialized algorithms to interpret brain activity and guide the arm's movements.
The UC Davis Center for Geotechnical Modeling has been upgraded with a 30-foot radius centrifuge, enabling researchers to simulate pressures deep in the ground and study soil liquefaction during earthquakes. The network allows for remote collaboration and data sharing among researchers across the country.
A hybrid approach combining angioplasty and robotically enhanced minimally invasive direct coronary artery bypass (MIDCAB) shows promise in treating coronary artery disease. The procedure allows for a small incision and avoids opening the chest, reducing postoperative discomfort and aesthetic results.
Researchers developed a neural prosthesis allowing a monkey to grasp and hold food using only its brain. The prosthetic arm is controlled by an algorithm that intercepts signals from the motor cortex, allowing the monkey to learn through biofeedback and refine its movements.
Recent studies have shed new light on how to decode nerve cell signals, simplifying the development of thought-controlled prosthetic devices. By analyzing activity in large populations of nerve cells, researchers hope to create more accurate brain-machine interfaces that can restore movement in paralyzed individuals.
Scientists use Zoe, an autonomous solar-powered rover, to explore the Atacama Desert and test robotic capabilities. They aim to detect signatures of microbial life remotely, which will aid in future human missions to Mars.
Astronomers launch RoboNet, a global network of robotic telescopes using intelligent software to rapidly observe sudden changes in astronomical objects. The project aims to discover Earth-like planets and study Gamma Ray Bursts, exploiting the large size of the telescopes and sensitive instrumentation.
A study found that robotic doctor visits increased patient comfort and accessibility to medical information, with 57% suggesting it should become a standard practice. Patients preferred having their own physician conduct telerounds over others.
A new robotic device called RAFFE has been developed by scientists from the University of Toronto and the University of Calgary to safely collect fingerprint evidence from suspicious packages. The device uses heat and fumes to react with oils in fingerprints, turning them white, allowing for photographing before safe disposal.
Jennifer Lewis and her team developed novel inks that can create three-dimensional periodic structures with feature sizes 100 times smaller than before. The ink is based on polyelectrolyte mixtures and can be tailored to control its flow through fine deposition nozzles.
The minimally invasive surgical techniques made possible by the robot system can give the same surgical result as open-chest techniques with less impact on young patients' bodies. Robot-assisted surgery may be a good option for certain defects and reduces hospital stays, operative trauma, cosmetic impact, and overall recovery time.
Scientists use Raman spectrometer to analyze minerals, gases and liquids on the sea floor, tracking carbon dioxide levels and distinguishing between gas and liquid forms. The device could potentially trap carbon dioxide in clathrate hydrates, a promising method for climate change mitigation.
Researchers found that women with coronary artery disease and an implantable cardioverter-defibrillator have a lower rate of sustained ventricular tachycardia or fibrillation compared to men. Additionally, automated external defibrillators (AEDs) in health clubs reversed sudden cardiac death in six out of eight victims, supporting the ...
The National Robotics Engineering Consortium will lead the development of perception and path planning within the Autonomous Navigation System. The team aims to advance mobile robotics and increase soldier safety by eliminating direct UGV operation.
The National Robotics Engineering Consortium (NREC) will lead the development of a highly mobile vehicle suitable for various expeditionary missions conducted by the Marines. The project aims to deliver a complete system solution to address the Marines' needs, with an expected initial fielding in 2006.
The Illinois team developed a new technique to create three-dimensional microchannel networks that improve fluid mixing efficiency compared to traditional two-dimensional channels. The technology also enables the creation of self-healing materials with integrated 'circulatory systems' for transporting repair chemicals.
A Virginia Tech researcher is developing a fleet of low-cost, miniature autonomous underwater vehicles (AUVs) to collect elusive environmental data in Hog Island Bay. The AUVs will be equipped with sensors to monitor water parameters and work cooperatively to gather data that can't be collected with traditional methods.
The University of California, Berkeley's robotic telescope has captured the earliest image of a gamma-ray burst's optical afterglow, offering unprecedented data for theorists to study. The data provides key constraints for physical models of gamma-ray bursts and will help astronomers better understand these enigmatic events.
