Human-like behavioral variability blurs the distinction between a human and a machine in a nonverbal Turing test

Posted by in categories: biotech/medical, robotics/AI

Human-like temporal variability in movements is a powerful hint that humans use to ascribe humanness to robots.


A team of researchers at the University of Geneva has found that ketamine is unlikely to be addictive to people who use it for extended periods of time. In their paper published in the journal Nature, the group describes their study of the impact of the synthetic compound on the brains of mice and what they learned about its impact on different brain regions. Rianne Campbell and Mary Kay Lobo, with the University of Maryland School of Medicine have published a News and Views piece in the same journal issue outlining the work done by the team in Switzerland.

Do autonomous driving features really make roads safer?

Posted by in categories: policy, robotics/AI, transportation

In recent years, more vehicles include partially autonomous driving features, such as blind spot detectors, automatic braking and lane sensing, which are said to increase safety. However, a recent study by researchers from The University of Texas at Austin finds that some of that safety benefit may be offset by people driving more, thereby clogging up roads and exposing themselves to more potential crashes.

The study, published recently in Transportation Research Part A—Policy and Practice, found that drivers with one or more of these autonomous features reported higher miles traveled than those of similar profiles who didn’t have them. This is important, because miles traveled is one of the most—if not the most—significant predictor of . The more you drive, the more likely you are to crash.

“What we showed, without any ambiguity in our results, is that after embracing autonomous features, people tend to drive more,” said Chandra Bhat, one of the authors on the project and professor in the Cockrell School of Engineering’s Department of Civil, Architectural and Environmental Engineering. “There are certainly engineering benefits to these features, but they are offset to a good extent because people are driving more and exposed more.”

Flowers can hear buzzing bees—and it makes their nectar sweeter

Posted by in category: biotech/medical

This single study has cracked open an entirely new field of scientific research, which Hadany calls phytoacoustics.

Veits wants to know more about the underlying mechanisms behind the phenomenon the research team observed. For instance, what molecular or mechanical processes are driving the vibration and nectar response? She also hopes the work will affirm the idea that it doesn’t always take a traditional sense organ to perceive the world.

“Some people may think, How can [plants] hear or smell?” Veits says. “I’d like people to understand that hearing is not only for ears.”

Scientists fabricate high-performance large-area perovskite submodules for solar cells

Posted by in categories: chemistry, engineering, physics, solar power, sustainability

Perovskite solar cells (PSCs) are promising solar technologies. Although low-cost wet processing has shown advantages in small-area PSC fabrication, the preparation of uniform charge transport layers with thickness of several nanometers from solution for meter-sized large area products is still challenging.

Recently, a research group led by Prof. LIU Shengzhong from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed a facile surface redox engineering (SRE) strategy for vacuum-deposited NiO x to match the slot-die-coated perovskite, and fabricated high-performance large-area perovskite submodules.

This work was published in Joule (“Surface redox engineering of vacuum-deposited NiO x for top-performance perovskite solar cells and modules”).

Cyber-Criminal Offers 5.4m Twitter Users’ Data

Posted by in category: cybercrime/malcode

A database containing 5.4m Twitter users’ data is reportedly for sale on a popular criminal forum. Twitter is investigating the issue, which the seller said exploited a vulnerability in its systems reported in January.

The seller, using the nickname ‘devil,’ advertised the data on the Breached Forums site and demanded at least $30,000 for it. They said that the database contains the phone numbers and email addresses of users, including celebrities and companies.

The hack reportedly exploits a vulnerability first reported by a HackerOne user known as ‘zhirinovskiy.’ That bug enabled “an attacker with a basic knowledge of scripting/coding” to find a Twitter user’s phone number and email address, even if the user has hidden them in privacy settings. The attacker explained how to exploit the bug in their HackerOne report. Twitter acknowledged the bug and fixed it five days later.

Twin physically unclonable functions (PUFs) based on carbon nanotube arrays to enhance the security of communications

Posted by in categories: computing, encryption, internet, nanotechnology, security

As the amount of data stored in devices and shared over the internet continuously increases, computer scientists worldwide are trying to devise new approaches to secure communications and protect sensitive information. Some of the most well-established and valuable approaches are cryptographic techniques, which essentially encrypt (i.e., transform) data and texts exchanged between two or more parties, so that only senders and receivers can view it in its original form.

Physical unclonable functions (PUFs), devices that exploit “random imperfections” unavoidably introduced during the manufacturing of devices to give physical entities unique “fingerprints” (i.e., trust anchors). In recent years, these devices have proved to be particularly valuable for creating , which are instantly erased as soon as they are used.

Researchers at Peking University and Jihua Laboratory have recently introduced a new system to generate cryptographic primitives, consisting of two identical PUFs based on aligned carbon nanotube (CNT) arrays. This system, introduced in a paper published in Nature Electronics, could help to secure communications more reliably, overcoming some of the vulnerabilities of previously proposed PUF devices.
