In Reply to Modern Einstein,Next Stephen Hawking and Freud-With Reply of Howard Bloom

Posted by in category: journalism

Dear Mr Howard Bloom-The modern Einstein,next Stephen Hawking and Freud,

Its an honor to be known by you. Your work on Space Sciences are revolutionary Sir. Your association and projects with CalTech and other scientific organizations will change the world we live in.I also have great passion in Space and Astronomy Sciences and that led me attending multiple workshops of NASA apart from attending its three credit course and organizing its prestigious essay contest in Indian schools in India and Abroad. I have searched NASA websites for close to 16 years and have found that it stores trillions of pages of materials where you can learn and research without help of any other source. I also have written my fundamental concept called The Cosmic Mask which I have sent to National Research Council and The American Astronomical Society for their review. I plan to publish it on AAS website.My two books–The Cosmic Mask(Not the Fundamental Concept) and NASA-The Story of Manned and Unmanned Missions is dedicated to youths of this world for their love and passion in Space and Astronomy Sciences.

I want to know how you can associate me with National Space Society and other organizations you are associated with.

You asked me few things and here is what I think.

Novel optics for ultrafast cameras create new possibilities for imaging

Posted by in category: electronics

MIT researchers have developed novel photography optics that capture images based on the timing of reflecting light inside the optics, instead of the traditional approach that relies on the arrangement of optical components. These new principles, the researchers say, open doors to new capabilities for time- or depth-sensitive cameras, which are not possible with conventional photography optics.

Specifically, the researchers designed new optics for an ultrafast sensor called a streak that resolves images from ultrashort pulses of light. Streak cameras and other ultrafast cameras have been used to make a trillion-frame-per-second video, scan through closed books, and provide depth map of a 3D scene, among other applications. Such cameras have relied on conventional optics, which have various design constraints. For example, a with a given , measured in millimeters or centimeters, has to sit at a distance from an imaging sensor equal to or greater than that focal length to capture an image. This basically means the lenses must be very long.

Printed electronics breakthrough could lead to flexible electronics revolution

Posted by in categories: biotech/medical, cyborgs, health, nanotechnology

A new form of electronics manufacturing which embeds silicon nanowires into flexible surfaces could lead to radical new forms of bendable electronics, scientists say.

In a new paper published today in the journal Microsystems and Nanoengineering, engineers from the University of Glasgow describe how they have for the first time been able to affordably ‘print’ high-mobility semiconductor onto flexible surfaces to develop high-performance ultra-thin electronic layers.

Those surfaces, which can be bent, flexed and twisted, could lay the foundations for a wide range of applications including video screens, improved health monitoring devices, implantable devices and synthetic skin for prosthetics.

Terahertz technology creates new insight into how semiconductor lasers work

Posted by in categories: energy, futurism

Lasers are widely used as high power sources of light operating at a specific frequency. But how does this frequency get selected when a laser is turned on, and how quickly?

Pioneering engineers working with technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made.

The development of specific terahertz equipment has allowed them to investigate this process for the first time. Their results, published in Nature Communications, will underpin the future development of semiconductor lasers, including those used in public and private sector-owned telecommunications systems.

The behavior of water—scientists find new properties of H2O

Posted by in category: energy

A team of scientists has uncovered new molecular properties of water—a discovery of a phenomenon that had previously gone unnoticed.

Liquid water is known to be an excellent transporter of its own autoionization products; that is, the charged species obtained when a water molecule (H2O) is split into protons (H+) and hydroxide ions (OH). This remarkable property of water makes it a critical component in emerging electrochemical energy production and storage technologies such as fuel cells; indeed, life itself would not be possible if water did not possess this characteristic.

Water is known to consist an intricate network of weak, directional interactions known as . For nearly a century, it was thought that the mechanisms by which water transports the H+ and OH ions were mirror images of each other – identical in all ways except for directions of the hydrogen bonds involved in the process.

3D printed biomaterials for bone tissue engineering

Posted by in categories: 3D printing, bioengineering, bioprinting, biotech/medical, life extension

When skeletal defects are unable to heal on their own, bone tissue engineering (BTE), a developing field in orthopedics can combine materials science, tissue engineering and regenerative medicine to facilitate bone repair. Materials scientists aim to engineer an ideal biomaterial that can mimic natural bone with cost-effective manufacturing techniques to provide a framework that offers support and biodegrades as new bone forms. Since applications in BTE to restore large bone defects are yet to cross over from the laboratory bench to clinical practice, the field is active with burgeoning research efforts and pioneering technology.

Cost-effective three-dimensional (3D) printing (additive manufacturing) combines economical techniques to create scaffolds with bioinks. Bioengineers at the Pennsylvania State University recently developed a composite ink made of three materials to 3D print porous, -like constructs. The core materials, polycaprolactone (PCL) and poly (D, L-lactic-co-glycolide) acid (PLGA), are two of the most commonly used synthetic, biocompatible biomaterials in BTE. Now published in the Journal of Materials Research, the materials showed biologically favorable interactions in the laboratory, followed by positive outcomes of in an animal model in vivo.

Since bone is a complex structure, Moncal et al. developed a bioink made of biocompatible PCL, PLGA and hydroxyapatite (HAps) particles, combining the properties of bone-like mechanical strength, biodegradation and guided reparative growth (osteoconduction) for assisted natural bone repair. They then engineered a new custom-designed mechanical extrusion system, which was mounted on the Multi-Arm Bioprinter (MABP), previously developed by the same group, to manufacture the 3D constructs.
