Teleportation of quantum states promises to play a central role in securing the information superhighway of tomorrow.
In spite of the headway that’s been made, the process remains slow and kind of clunky. That could change, with scientists using a new process that could efficiently teleport states of light to form an image using a single pair of entangled photons.
The team, from South Africa, Germany, and Spain, is hopeful that the innovation may help build the secure networks of the future: if the key data isn’t transmitted, then it can’t be stolen.
An innovative floating offshore wind turbine prototype was launched in New Bedford, Massachusetts this week. Instead of a single anchor tower, the approach uses a pyramid base that can also passively orient itself in the direction of the blowing wind.
As wind turbines get bigger and sweep larger areas in a single rotation, wind farms move offshore to gain maximum advantage from powerful sea winds. Over the years, the costs of wind-based energy have been plummeting, but as wind farms are set up farther into the sea, the costs and time required to set up new wind farms are bound to increase.
Scientists have discovered a new way to destroy cancer cells. Stimulating aminocyanine molecules with near-infrared light caused them to vibrate in sync, enough to break apart the membranes of cancer cells.
Aminocyanine molecules are already used in bioimaging as synthetic dyes. Commonly used in low doses to detect cancer, they stay stable in water and are very good at attaching themselves to the outside of cells.
The research team from Rice University, Texas A&M University, and the University of Texas, says the new approach is a marked improvement over another kind of cancer-killing molecular machine previously developed, called Feringa-type motors, which could also break the structures of problematic cells.

A short history of the Web
Posted in computing, internet, robotics/AI
The World Wide Web was first tested on Christmas Day in 1990. Tim Berners-Lee and Robert Cailliau set up successful communication between a web browser & server via the Internet.
Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.
CERN is not an isolated laboratory, but rather the focal point for an extensive community that includes more than 17 000 scientists from over 100 countries. Although they typically spend some time on the CERN site, the scientists usually work at universities and national laboratories in their home countries. Reliable communication tools are therefore essential.
The basic idea of the WWW was to merge the evolving technologies of computers, data networks and hypertext into a powerful and easy to use global information system.
Poorly secured Linux SSH servers are being targeted by bad actors to install port scanners and dictionary attack tools with the goal of targeting other vulnerable servers and co-opting them into a network to carry out cryptocurrency mining and distributed denial-of-service (DDoS) attacks.
“Threat actors can also choose to install only scanners and sell the breached IP and account credentials on the dark web,” the AhnLab Security Emergency Response Center (ASEC) said in a report on Tuesday.
In these attacks, adversaries try to guess a server’s SSH credentials by running through a list of commonly used combinations of usernames and passwords, a technique called dictionary attack.
