Next Generation Spacesuit Gets Tested in Weightlessness

Posted by in category: space

Considerable effort goes into the design of space suits and space agencies across the world are always working on improvements to enhance safety and mobility of the designs. NASA is now working with Collins Aerospace to develop their next generation spacesuit for the International Space Station. The new designs are tested extensively and recently, the new design was subjected to a ZeroG flight on board a diving aircraft.

Collins Aerospace are an American technology company based in Charlotte in North Carolina. They were selected to develop the new suit as a replacement to the existing garments used by NASA. The official name of the suits are extravehicular mobility units and they have been worn for over two decades.

Once a prototype for the new suit was developed the project entered its test phase with one of the key elements, the microgravity or ZeroG test. To simulate ZeroG aircraft are taken on a parabolic flight. The pilot takes the plane to an altitude of around 24,000 feet and then pulls up increasing the climb angle to 45 degrees. Reaching an altitude of about 32,000 feet the plane is then put into a dive where the plane and its occupants experience ZeroG. For those inside, they will float around for between 20 and 30 seconds.

Case study features successful treatment of the oldest patient to achieve remission for leukemia and HIV

Posted by in categories: biotech/medical, genetics

City of Hope, one of the largest cancer research and treatment organizations in the United States, treated the oldest person to be cured of a blood cancer and then achieve remission for HIV after receiving a blood stem cell transplant from a donor with a rare genetic mutation. Research published in the New England Journal of Medicine today demonstrates that older adults with blood cancers who receive reduced intensity chemotherapy before a stem cell transplant with donor cells that are resistant to HIV may be cured of HIV infection.

Paul Edmonds, 68, of Desert Springs, California, is the fifth person in the world to achieve remission for and HIV after receiving stem cells with a rare genetic mutation, homozygous CCR5 Delta 32. That mutation makes people who have it resistant to acquiring HIV. Edmonds is also the person who had HIV the longest—for over 31 years—among these five patients.

Can Quantum Computers be Beaten by Classical Computers?

Posted by in categories: computing, information science, quantum physics

This post is also available in: he עברית (Hebrew)

Researchers from NYU discovered that classical computers could keep up with or even surpass quantum computers in certain circumstances. Classical computers can get a boost in speed and accuracy by adopting a new innovative algorithmic method, which could mean that they still have a future in a world of quantum computers.

Many experts believe that quantum computing is the future, and that we are veering away from classical computing, primarily because classical computers are significantly slower and weaker than their quantum-based counterparts. However, turns out that quantum computers are delicate and prone to information loss, and even if information is preserved it is difficult to convert it to classical information necessary for practical computation.

A new optical metamaterial makes true one-way glass possible

Posted by in category: materials

A new approach has allowed researchers at Aalto University to create a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific electromagnetic properties, which means scientists can create materials with features desirable for industrial applications.

The new metamaterial takes advantage of the nonreciprocal magnetoelectric (NME) effect. The NME effect implies a link between specific properties of the material (its magnetization and polarization) and the different field components of light or other . The NME effect is negligible in , but scientists have been trying to enhance it using metamaterials and metasurfaces because of the technological potential this would unlock.

The work is published in the journal Nature Communications.

Experimental implant could end the need for insulin injections

Posted by in categories: biotech/medical, health

A new kind of implant could one day make it far easier for people with type 1 diabetes to manage their disease. The insulin-making implant is a mixture of transplanted islets cells and medical technology, inserted just below the skin in a person’s arm, and if it perform well in clinical trials, it could potentially last for years.

The challenge: Insulin is a hormone that our bodies use to convert sugar in our blood into energy. People with type 1 diabetes don’t produce enough (or any) insulin — if left untreated, this causes dangerously high blood sugar levels, leading to serious health issues or even death.

Regularly checking blood sugar levels and injecting synthetic insulin when they’re high is the most common way to treat type 1 diabetes, but it isn’t the only way.
