Nice.

In a pair of firsts, researchers at Case Western Reserve University and Massachusetts Institute of Technology have shown that the drug candidate phenanthriplatin can be more effective than an approved drug in vivo, and that a plant-virus-based carrier successfully delivers a drug in vivo.

Triple-negative breast cancer tumors of mice treated with the phenanthriplatin –carrying nanoparticles were four times smaller than those treated either with cisplatin, a common and related chemotherapy drug, or free phenanthriplatin injected intravenously into circulation.

Scientists can now identify the exact location of a single atom in a silicon crystal, a discovery that is key for greater accuracy in tomorrow’s silicon based quantum computers.

It’s now possible to track and see individual phosphorus atoms in a silicon crystal allowing confirmation of quantum computing capability, but which also has use in nano detection devices.

How do organisms without brains make decisions? Most of life is brainless and the vast majority of organisms on Earth lack neurons altogether. Plants, fungi and bacteria must all cope with the same problem as humans — to make the best choices in a complex and ever-changing world or risk dying — without the help of a simple nervous system in many cases.

A team of researchers from New Jersey Institute of Technology (NJIT), the University of Sydney, the University of Sheffield and the University of Leeds recently studied this problem in the unicellular slime mold, Physarum polycephalum, a single-cell organism that can grow to several square meters in size. This giant cell, which typically lives in shady, cool and moist areas of temperate forests, spreads out to search its environment like an amoeba, extending oozy tendrils along the forest floor in search of its prey of fungi, bacteria and decaying vegetable matter.

Neither plant, animal nor fungus, P. polycephalum has become an unlikely candidate for studies of cognition, due to its spectacular problem-solving abilities. In recent studies, Physarum has been shown to solve labyrinth mazes, make complicated trade-offs, anticipate periodic events, remember where it has been, construct transport networks that have similar efficiency to those designed by human engineers and even make irrational decisions — a capability that has long been viewed as a by-product of brain circuitry.

Very nice; researchers have now discovered a method for viewing deep brain imaging through using NIR light at wavelengths of 1600–1870nm Very big deal especially for patients with things like Giloblastoma Multiforme (GBM), and other neuro disorders and diseases.

I remember when my two aunts suffered from GBM, and many doctors could not get iimaging view in some areas of my aunts brains which would have been beneficial in understanding how ingrain the GBM was in their brain cells. So, hopefully this finding will help others in getting better answers to diseases like GBM and in turn better treatment as well developed.

Near-IR light at wavelengths of 1600–1870nm offers the best transmittance for deep brain imaging.

Seokheun “Sean” Choi, assistant professor of computer and electrical engineering at Binghamton University, along with two of his students, developed the device, a microbial fuel cell that runs on the bacteria available in a few drops of dirty water. They report on their invention in a new paper published online in the journal Biosensors and Bioelectronics (“A disposable power source in resource-limited environments: A paper-based biobattery generating electricity from wastewater”).

A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions.

Robotic exoskeletons, long a staple of sci-fi novels, comic books, and movies, are now part of the real world—and they’ve mostly followed the sci-fi model. That is, exoskeletons are wearable robots. All metal, all the time. But metal suits are heavy and power hungry, and the human body isn’t metal. If you actually plan to use an exoskeleton for an extended period of time, this can be a bit of a design flaw.

That’s where a new exosuit developed by SRI International is looking to flip the script. Instead of working to build exoskeletons—which are rigid like their namesake—SRI is using soft robotics to make lightweight, wearable “exomuscles” and “exotendons.”

Instead of a human-shaped heavy metal frame, SRI’s exosuit is soft, pliable, and intelligent. The suit learns and adapts to its wearer’s movements to give them a boost when needed. It’s quick to put on and relatively energy efficient.

(Bloomberg) — China is speeding up efforts to design and build a manned deep-sea platform to help it hunt for minerals in the South China Sea, one that may also serve a military purpose in the disputed waters.

Such an oceanic “space station” would be located as much as 3,000 meters (9,800 feet) below the surface, according to a recent Science Ministry presentation viewed by Bloomberg. The project was mentioned in China’s current five-year economic plan released in March and ranked number two on a list of the top 100 science and technology priorities.

Authorities recently examined the implementation of the project and decided to accelerate the process, according to the presentation.

Getting a handle on cloud-based virtual operations is no easy task. Next month researchers from the Intelligence Advance Research Projects Activity (IARPA) will introduce a new program that looks to address that management concern by developing better technology to manage and secure Virtual Desktop Infrastructure (VDI) environments.

+More on Network World: Intelligence agency wants computer scientists to develop brain-like computers +

IARPA, the radical research arm of the of the Office of the Director of National Intelligence will introduce the Virtuous User Environment (VirtUE) which it says aims to “creatively define and develop user environments that are more dynamic, secure, auditable, transferrable, and efficient than the current offerings provided by traditional physical workstations and commercial VDI; develop innovative, dynamic analytics and infrastructures that can leverage these newly developed user environments to both automatically detect and deter security threats that IC user environments will be subject to in the new cloud infrastructure.”

According to Einstein’s theory of general relativity (GR), black holes are ferocious beasts able to swallow and destroy everything within their reach. Their strong gravitational pull deforms the space-time causal structure in such a way that nothing can get out of them once their event horizon is crossed. The fate of those incautious observers curious enough to cross this border is to suffer a painful spaghettification process due to the strong tidal forces before being destroyed at the center of the black hole.
