Nanotechnology To Make Holographic Applications More Secure And Efficient

Making Holographic Apps more secured and efficient.


Since its birth, holograms have been extensively used to serve security systems and related purposes. The making of a hologram, dissecting it to pieces and again rejoining the blocks involves a steady orientation of lenses which encodes the information with depth perception that could be deciphered later according to requirement.

It’s hard to imagine a 21st century city running smooth without an immense use of holograms, small or big sized 2D cards with 3D engraved pictures that are present in credit cards, grocery objects, books, biomedical devices and in other objects requiring retrievable information to be stored.

In terms of concealing product information, these sticker based fancy stuffs were up to the mark, until technology escalated beyond imagination. Even a previously measured safe encryption suffered from threat and these tools became fragile. Researchers initialized various approaches to hit the safest and complex path, among which nanotechnology had an answer in store for them. A research team from the Harvard John A. Paulson School of Engineering and Applied Sciences had recently forced polarization to concise holograms, comprising of tiny light-polarization sensitive nanostructures to generate numerous ones depending upon the polarization configuration of light.

Team discovers new HIV vaccine target

A team led by scientists at the National Institutes of Health (NIH) has reported a research trifecta. They discovered a new vulnerable site on HIV for a vaccine to target, a broadly neutralizing antibody that binds to that target site, and how the antibody stops the virus from infecting a cell. The study was led by scientists at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases, part of NIH.

The new target is a part of HIV called the fusion peptide, a string of eight amino acids that helps the virus fuse with a cell to infect it. The fusion peptide has a much simpler structure than other sites on the virus that HIV vaccine scientists have studied.

The scientists first examined the blood of an HIV-infected person to explore its ability to stop the virus from infecting cells. The blood was good at neutralizing HIV but did not target any of the vulnerable spots on the virus where broadly neutralizing HIV antibodies (bnAbs) were known to bind.

Scientists have discovered a cell that does something they thought was impossible

Interesting…

Odd, but definitely interesting.


For a long time it has been thought that all eukaryotes — organisms in which the DNA is enclosed in a membrane including almost all life we can see — had to contain mitochondria.

Known as the “power house” of the cell, these little subunits within the cell provide the organisms with energy and were thus thought to be essential.

But it now seems that actually they might not be that essential, as researchers describe the first eukaryote known that lacks mitochondria.

Head transplant ops ‘will work’, say experts… but the side effects could be the worst form of insanity ever experienced by a human

A RUSSIAN man who has a debilitating illness has volunteered to become the first person to undergo a head transplant – but experts say the side effects of the procedure could be worse than death.

Valery Spiridonov, 30, suffers from Werdnig-Hoffmann disease, a rare form of spinal muscular atrophy.

The controversial operation will involve cooling his head to around 12 degrees Celsius, cutting it from his body and connecting it to the donated body of a brain-dead person.

Scientific Research Needs a Trustless Blockchain Architecture to Be Trusted

Dr. Greg Irving, a Clinical Lecturer from the University of Cambridge, recently authored a research project on the potential impact of blockchain technology on scientific research. While the use is not novel in principle, it underscores the very reason blockchain was created.

Why Scientific Research?

Irving, and rightfully so, says that in order to truly trust scientific research the reader’s must know that the content and subsequent conclusions of the research has maintained its integrity throughout editing and publishing. The author references “outcome switching, data dredging, and selective publication” as just a some of the potential pitfalls that can result in bastardized research. How then can researchers increase the trust that their research is has not been tampered with? In response Irving writes.

Nanotechnology improves holographic capabilities

Holograms are a ubiquitous part of our lives. They are in our wallets—protecting credit cards, cash and driver’s licenses from fraud—in grocery store scanners and biomedical devices.

Even though holographic technology has been around for decades, researchers still struggle to make compact holograms more efficient, complex and secure.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have programmed into compact holograms. These holograms use nanostructures that are sensitive to polarization (the direction in which light vibrates) to produce different images depending on the polarization of . This advancement, which works across the spectrum of light, may improvement anti-fraud holograms as well as those used in entertainment displays.

We’re Closer Than Ever to Bringing the Dead Back to Life

The use of cryogenics, for now, borders on science fiction—but that hasn’t stopped scientists and wealthy enthusiasts from trying to make it a reality.

Humai, an L.A.-based robotics company, hopes to freeze human brains after death with the expectation that technology will soon catch up—allowing the brain to be resurrected in an artificial body. Neuroscientists have excessively cautioned about lending cryogenics credence, but scientific research has blurred the definition of death and the consensus on when it occurs.

For centuries, death was called at the moment the heart stopped beating. However, medicine has evolved to the point that cardiopulmonary resuscitation (CPR) is now a common life-saving technique incorporated in basic first aid training, along with more advanced forms of resuscitation—like defibrillators—that can restart the heart. Several cases have been cited where a person under cardiac arrest has been brought back to life hours after they’ve technically died, when cooling processes and correct resuscitation procedures are implemented. According to a 2012 study published in Nature, skeletal muscle stem cells can retain their ability to regenerate for up to 17 days after death, redefining death as occurring in steps rather than at one single moment.

The Major Mouse Testing Program AMA on Reddit!

Monday May 16th 17:00 GMT 13:00 EST 10:00 PST r/futurology.


The Major Mouse Testing Program is an ambitious project of the International Longevity Alliance, seeking to speed up scientific progress in the field of regenerative medicine and bio-gerontology. After ILA experts conducted an analysis of bottlenecks preventing the development of life extension technologies, it was revealed that one of these bottlenecks is the deficiency of robust animal data for the potential of different compounds to promote health and extend maximum lifespan. Without this data promising interventions cannot enter clinical trials and become available to the general public.

The ILA decided to initiate a fundraising program to fund a series of these high-risk studies: Major Mouse Testing Program. We are currently running a crowdfunding campaign for the first experiment to test a combination of Senolytics. They have been shown to help seek out and destroy senescent “death resistant” cells and improve various aspects of health. We wish to see if Senolytics are able increase maximum lifespan in addition to healthspan promotion. We have big plans for the future with combination testing of senolytics, stem cells and more to help speed up scientific progress. So go ahead ASK US ANYTHING!
