Marines Adapting Live-Fire Training Using Robots

Posted by in categories: military, robotics/AI

At Camp Pendleton, Marines are testing a new, cutting edge form of live-fire training using robotic targets.

Stationary and on-rails targets are all well and good, but enemy combatants haven’t behaved like that since the formal battle lines of the Revolutionary War. It’s long past time for a training program that provides a more accurate simulation of today’s combat situations, and the Marines of Camp Pendleton are taking steps toward just that.

Multi-scale simulations solve a plasma turbulence mystery

Posted by in categories: nuclear energy, particle physics, supercomputing

Solving the turbulence plasma mystery.

Cutting-edge simulations run at Lawrence Berkeley National Laboratory’s National Energy Research Scientific Computing Center (NERSC) over a two-year period are helping physicists better understand what influences the behavior of the plasma turbulence that is driven by the intense heating necessary to create fusion energy. This research has yielded exciting answers to long-standing questions about plasma heat loss that have previously stymied efforts to predict the performance of fusion reactors and could help pave the way for this alternative energy source.

The key to making fusion work is to maintain a sufficiently high temperature and density to enable the atoms in the reactor to overcome their mutual repulsion and bind to form helium. But one side effect of this process is turbulence, which can increase the rate of plasma, significantly limiting the resulting energy output. So researchers have been working to pinpoint both what causes the turbulence and how to control or possibly eliminate it.

How cancer cells fuel their growth

Posted by in categories: biotech/medical, materials

Pretty cool.

Scientists report that amino acids, not sugar, supply most building blocks for cancerous tumor cells. Cancer cells are notorious for their ability to divide uncontrollably and generate hordes of new tumor cells. Most of the fuel consumed by these rapidly proliferating cells is glucose, a type of sugar.

Scientists had believed that most of the cell mass that makes up new cells, including cancer cells, comes from that glucose. However, MIT biologists have now found, to their surprise, that the largest source for new cell material is amino acids, which cells consume in much smaller quantities.

Microsoft and Google employees on US national guard may join cyber war against Islamic State

Posted by in categories: cybercrime/malcode, military

U.S. Defense Secretary Ash Carter said the National Guard’s cyber squadrons will play an increasingly important role in assessing the vulnerabilities of U.S. industrial infrastructure and could be asked to join the fight against Islamic State.

The National Guard – a reserve military force that resides in the states but can be mobilized for national needs – is a key part of the military’s larger effort to set up over 120 cyber squadrons to respond to cyber attacks and prevent them.

One such unit, the 262nd squadron, is a 101-person team that includes employees of Microsoft and Alphabet’s Google. The unit is “famous throughout the country” for several high profile vulnerability assessments, Carter said at the Joint Base Lewis-McChord in Tacoma, Washington late on Friday.

Newly developed model of DNA sheds light on molecule’s flexibility

Posted by in categories: bioengineering, biotech/medical, computing, genetics, nanotechnology

Knowledge of how DNA folds and bends could offer new perspective on how it is handled within cells while also aiding in the design of DNA-based nano-scale devices, says a biomedical engineer at Texas A&M University whose new motion-based analysis of DNA is providing an accurate representation of the molecule’s flexibility.

The model, which is shedding new light on the physical properties of DNA, was developed by Wonmuk Hwang, associate professor in the university’s Department of Biomedical Engineering, and his Ph.D. student Xiaojing Teng. Hwang uses computer simulation and theoretical analysis to study biomolecules such as DNA that carry out essential functions in the human body. His latest model, which provides a motion-based analysis of DNA is detailed in the scientific journal ACS Nano. The full article can be accessed at

In addition to housing the genetic information needed to build and maintain an organism, DNA has some incredibly interesting physical properties that make it ideal for the construction of nanodevices, Hwang notes. For example, the DNA encompassed within the nucleus of one human cell can extend to four feet when stretched out, but thanks to a number of folds, bends and twists, it remains in a space no bigger than one micron – a fraction of the width of a human hair. DNA also is capable of being programmed for self-assembly and disassembly, making it usable for building nano-mechanical devices.

New ‘meta-skin’ to cloak objects from radars

Posted by in category: materials

New skin for keeping you under the radar.

Because the meta-skin is stretchable, it can be pulled tight to augment the range of radar frequencies trapped by the resonators.

The project set out to prove that that electromagnetic waves — “perhaps even the shorter wavelengths of visible light” — can be adequately suppressed with flexible, tunable liquid-metal technologies. The material is made up of rows of rings, with a radius of 0.1 inches (2.5mm) and gaps of 0.04 inches (1mm). They’re filled with galinstan, a metal alloy that remains liquid at room temperatures and is less toxic than metals who share this property, such as mercury. Each resonator acts like a small curved piece of liquid wire.
