To help or not to help?

In emergency situations, people tend to behave either egotistically or prosocially, with some individuals being more cooperative than others. A study published in Nature Scientific Reports found that most participants helped others less in emergency situations due to time pressure, while prosocial individuals were more willing to help.

Your smartwatch is giving away your ATM PIN

Researchers from Binghamton University and Stevens Institute of Technology found that smartwatches can crack private PINs with 80-percent accuracy on the first try. The study used data from embedded sensors in wearable devices to break codes without contextual information, highlighting security vulnerabilities in these devices.

Accelerating research into dark energy

Researchers at UCL have created a new approach to simulate virtual universes, allowing for accelerated research into the effects of dark energy and dark matter. By comparing results from large studies to computational models, scientists can gain more accurate predictions and explore alternative versions of these mysterious substances.

Making computers reason and learn by analogy

The structure-mapping engine (SME) enables computers to reason more like humans and make moral decisions by leveraging cognitive science theories. SME can handle the size and complexity of relational representations needed for visual reasoning, cracking textbook problems, and solving moral dilemmas.

RedEye could let your phone see 24-7

Researchers at Rice University developed RedEye, a technology that can provide computers with continuous vision, enabling wearables to see and remember what their owners need. By analyzing analog signals in real-time, RedEye improves energy efficiency and presents unique privacy advantages.

Social engineering: Password in exchange for chocolate

A large-scale study found that offering small gifts, such as chocolate, can increase the willingness of people to share their passwords with strangers due to the principle of reciprocity. In the experiment, 43.5% of participants shared their passwords when given chocolate beforehand, compared to 29.8% in control groups.

New design of primitive quantum computer finds application

Scientists at the University of Bristol have developed a new method to simulate a 'quantum walk' on a primitive quantum computer, which they claim can solve problems that classical computers cannot. The study suggests that these smaller quantum processors could outperform classical computing for specific tasks, such as 'Boson Sampling'.
