Most premature deaths in Mumbai and Delhi over two decades were caused by stroke (a medical condition that occurs when blood supply to the brain is cut off), due to inhalation of ultrafine suspended particles, revealed a study by the Indian Institute of Technology – Bombay (IITB).

The three-member IITB team attributed 35.3% premature deaths to cerebrovascular disease – arteries supplying blood to the brain is affected – as a result of being exposed to high levels of particulate matter of size less than 2.5 microns in diameter (PM2.5) between 1991 and 2015. Additionally, premature deaths due to ischemic heart disease (it falls under the group of cardiovascular diseases) and chronic obstructive pulmonary disease (COPD) stood at 33.3% and 22.9% during the same period.

A dangerous pollutant, PM2.5 can lodge deep into the lungs and cardiovascular system, giving rise to a host of problems from damage to lung tissue, sneezing, asthma attacks, migraines, headaches to even cancer and heart attacks. The elderly, children, and those with chronic lung disease, influenza, or asthma, are especially sensitive to the effects of PM2.5.

It underscores the fact that not all minds that wander are lost. University of British Columbia philosopher Evan Thompson, author of Waking, Dreaming, Being: Self and Consciousness in Neuroscience, Meditation, and Philosophy, says the DMN’s mental meanderings are “the baseline state of you as a cognitive system.” It’s tremendously pragmatic: being able to remember the past, plan for the future, and happen upon creative insights are all essential tools for navigating life. While he was hesitant to mix the word “suffering,” which is so loaded in ancient Asian religious traditions, with the “default mode,” which is of a contemporary neural vintage, the two connect in the way that suffering arises when people concretize the fleeting swirls of thought, especially around conceptions of self. Still, he says, there’s “particular kind of stickiness” that can come when DMN activity grows overly self-centered.

Default-mode content involves an image of self, one that’s easy to become attached to. These self-conceptions are “affectively charged,” he says; they carry lots of emotional weight. “We constantly think that it’s not just another thought, that [the image of self] is something real, not just an mental image.”

Precise memory, rather than general memory, is critical for knowing details such as the specific color, shape and location of a building you are looking for, rather than simply knowing the part of town it’s in. This type of memory is crucial for normal functioning, and it is often lost in people with serious memory disorders.

“We show that it is possible to target the portion of the brain responsible for this type of memory and to improve it,” said lead author Joel Voss, assistant professor of medical social sciences at Northwestern University Feinberg School of Medicine. “People with brain injuries have problems with precise memory as do individuals with dementia, and so our findings could be useful in developing new treatments for these conditions.”

By stimulating the brain network responsible for spatial memory with powerful electromagnets, scientists improved the precision of people’s memory for identifying locations. This benefit lasted a full 24 hours after receiving stimulation and corresponded to changes in brain activity.

Hoverboards and certain cell phones powered by lithium-ion batteries occasionally go up in flames. Scientists now have a new plan for squelching these fires before they flare out of control: incorporating a flame retardant in the battery that’s released if temperatures get too toasty.

Within lithium-ion batteries, ions travel between positive and negative electrodes through a liquid called an electrolyte. But commonly used electrolytes are highly flammable. And if a short circuit in the battery produces enough heat, the electrolyte can ignite.

Can’t wait to see it.

Troops in remote regions around the world often struggle to operate with limited networks for data sharing and communication—an encumbrance that is amplified when U.S. troops need to share classified or otherwise secure data with each other and coalition partners. The usual process for sharing such information requires an end-to-end connection to secure servers via a dedicated digital “pipe” approved for the specific security level of data being transmitted. If that tactical network is overloaded or if a glitch causes a break in the digital chain, the message or data is typically lost and the process must be repeated until a connection is completed, potentially hindering the mission in fast-moving tactical situations. Additionally, the current computers and infrastructure needed to manage multiple levels of U.S. classified and coalition information are too bulky for tactical use in the field and can take months or longer to deploy.

To overcome this challenge, DARPA announced its Secure Handhelds on Assured Resilient networks at the tactical Edge (SHARE) program. SHARE aims to create a system where information at multiple levels of security classification could be processed on a single handheld device using a resilient secure network that links devices without needing to route traffic through secure data centers. This capability would be able to operate over existing commercial and military networks while maintaining the security of sensitive information and safety of operations.

“Troops forward deployed today have to have multiple laptops or devices that are approved to communicate at various levels of classification,” said Joe Evans, DARPA program manager.

Smart dust; himm I see many uses for this some good and some truly bad when in the wrong hands.

Pedro Aquila, Staff Writer Waking Times

Smart dust is a name given to extremely small computing particles, RFID chips, or other very small technologies.

A popular article from Extreme Tech describes it in the headline: “Smart dust: A complete computer that’s smaller than a grain of sand.” An article from War is Boring is titled “Future Military Sensors Could Be Tiny Specks of ‘Smart Dust’ New technologies allow for extremely small—and ubiquitous—military sensors.” A paper from University of California, San Diego describes smart dust:
