Is the antivirus program running on your computer really making your computers safer to use, say, for online banking? Is the parental control software you bought to keep your child off inappropriate sites transparent for the overall safety of your computer? New research shows security software might actually make online computing less safe.
Engineers have found a new way to induce and control boiling bubble formation, that may allow everything from industrial-sized boilers to advanced electronics to work better and last longer.
Academics have created an app that could help aid humanitarian rescue work in disaster-struck regions by using geographic data to map landscapes.
Surgeons and scientists have demonstrated that supervised, autonomous robotic soft tissue surgery on a live subject (in vivo) in an open surgical setting is feasible and outperforms standard clinical techniques in a dynamic clinical environment, according to a new study.
The brain produces feelings of confidence that inform decisions the same way statistics pulls patterns out of noisy data. This feeling of confidence is central to decision making, and, despite ample evidence of human fallibility, the subjective feeling relies on objective calculations.
Corporate data breaches seem to be on the rise, rarely a week passes without a company revealing that its database has been hacked and regrettably usernames, passwords, credit card details and its customers' personal information has been leaked on to the open internet. A new protection, nicknamed Phoney, may help.
Researchers have designed an equilibrium model to demonstrate the elastic stresses and suction pressure distribution between a soft hydrogel contact lens and an eye. The model allows arbitrary (radially-symmetric) lens shapes, eye shapes, and thickness profiles, and illustrates the dependence of pressure distribution on lens and eye shape.
A study of the most commonly-traded US stocks over the last 13-years finds 13,000 'bubbles,' or periods when the stocks were overpriced.
Online information on pancreatic cancer overestimates the reading ability of the overall population and lacks accurate information about alternative therapy, according to a study.
Long-eared bats are assisted in flight by their ears and body, according to a new study. The recent findings improve researchers' understanding of the bats' flying technique and could be significant for the future development of drones, among other things.
It is feasible to save lives from cardiac arrest through implementing and measuring this key intervention of Telephone-CPR instructions delivered by 9-1-1 dispatchers, a new report suggests.
Primary care practices in a large California Medicaid managed care plan offering teledermatology had an increased fraction of patients who visited a dermatologist compared with other practices, according to an article.
Scientists have demonstrated a compact, efficient single photon source that can operate on a chip at ambient temperatures. A highly directional single photon source could lead to compact, cheap, and efficient sources of quantum information bits for future quantum technological applications. The team is working on a new generation of devices to allow production of single photons straight from the chip into optical fibers, without any additional optical components.
Women expecting their first child but who are experiencing severe fear of childbirth (FOC) stand to dramatically benefit in reducing their anxieties with cognitive behavioural therapy (CBT) delivered via the internet, according to the results of new research.
Quantum information science and technology has emerged as a new paradigm for dramatically faster computation and secure communication in the 21st century. At the heart of any quantum system is the most basic building block, the quantum bit or qbit, which carries the quantum information that can be transferred and processed (this is the quantum analogue of the bit used in current information systems). The most promising carrier qbit for ultimately fast, long distance quantum information transfer is the photon, the quantum unit of light.
Scientists take an important step towards a logical quantum gate for photons.
An experimental study has found that readers rate texts generated by algorithms more credible than texts written by real journalists.
Researchers have developed and used a customized suite of technologies that allows a computer to train a dog autonomously, with the computer effectively responding to the dog based on the dog's body language
Smartphones and tablets come from Asia and America, European industry is far behind. Causes are unfolded by a new study, e.g. risk aversion made the companies offer own data services at high prices instead of using open internet. Competitive pressure by Europe-wide granting of mobile telephone licenses or deregulation of the radio spectrum might improve the situation.
The leading method for creating quantum bits, or qubits, currently involves exploiting the structural defects in diamonds. But researchers found that the same defect could be engineered in cheaper aluminum nitride. If confirmed by experiments, this could significantly reduce the cost of manufacturing quantum technologies.
