Naftalina viabiliza computador quântico a temperatura ambiente

Posted by in category: materials

Computadores qu nticos a temperatura ambiente.

É aí que entra a naftalina — mais especificamente, o material resultante da queima do naftaleno. A combustão gera um material à base de carbono, um pó fino que pode ser disperso em solventes como água ou etanol e depositado diretamente sobre uma pastilha de silício — depois de seco e visto ao microscópio o material se transforma em uma série de nanoesferas.

Bálint Náfrádi, da Universidade Politécnica Federal de Lausane, na Suíça, juntamente com colegas da Austrália e da Alemanha, descobriu que esse material consegue manter estáveis os spins dos elétrons em seu interior por até 175 nanossegundos — considera-se que a computação qu ntica pode se tornar prática a temperatura ambiente com qubits que sejam estáveis por mais do que 100 nanossegundos.

Matching Fund Donors Sought for SENS Universal Cancer Therapy Crowdfunding

Posted by in categories: biotech/medical, life extension

SENS has a fund match for its current campaign on lifespan.io, if you are concerned about cancer like me and you want to help directly fund a lab working on solutions please think about donating. smile


There is a month left to go in the SENS crowdfunding campaign that aims to accelerate development of an important component of a universal cancer therapy, a way to block the mechanisms of telomere lengthening that every type of cancer depends upon. The SENS Research Foundation and Lifespan.io volunteers are looking for donors to put up matching funds of a few thousand dollars or more, in order to take that news and that inducement to a number of conferences and other events over the next few weeks. More than 150 people have donated to the campaign to date, and we’d like to triple that number in the next 30 days.

To start things off, I’ll offer up $2,000 of my own funds: the next $2,000 in donations to this SENS cancer research initiative will be matched dollar for dollar. That is a start, and if you can join in to help out, please contact me to let me know. Can you help to make a difference here?

Glow-in-the-Dark ‘Smart Highways’ Replace Street Lights in the Netherlands

Posted by in category: transportation

Light-absorbing glow-in-the-dark road markings have replaced standard street lighting on a 500 meter stretch of highway in The Netherlands. This project is the first stage of a concept first unveiled back in 2012 by designer and innovator Daan Roosegaarde, who presented his ‘Smart Highway’ plans during Dutch Design Week. Roosegaarde’s design took top honors in the 2013 INDEX: Awards, and we’re excited to see it finally hit the streets!

‘Living hip’ grown in lab genetically engineered to stop arthritis

Posted by in categories: bioengineering, biotech/medical, genetics

Arthritis sufferers have been offered new hope after scientists grew a ‘living hip’ in the lab which not only replaces worn cartilage but stops painful joints returning.

Researchers in the US have used stem cells to grow cartilage in the exact shape of a hip joint while also genetically engineering the tissue to release anti-inflammatory molecules to fend off the return of arthritis.

The idea is to implant the perfectly shaped cartilage around the joint to extend its life before arthritis has caused too much damage to the bone.

Why the Cost of Living Is Poised to Plummet in the Next 20 Years

Posted by in categories: economics, education, employment, food, government, habitats, health, robotics/AI, transportation

Powered by developments in exponential technologies, the cost of housing, transportation, food, health care, entertainment, clothing, education and so on will fall, eventually approaching, believe it or not, zero.


People are concerned about how AI and robotics are taking jobs, destroying livelihoods, reducing our earning capacity, and subsequently destroying the economy.

In anticipation, countries like Canada, India and Finland are running experiments to pilot the idea of “universal basic income” — the unconditional provision of a regular sum of money from the government to support livelihood independent of employment.

Scientists develop way to upsize nanostructures into light, flexible 3D printed materials

Posted by in categories: 3D printing, energy, engineering, nanotechnology

For years, scientists and engineers have synthesized materials at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted in diminished performance and structural integrity.

Now, researchers led by Xiaoyu “Rayne” Zheng, an assistant professor of mechanical engineering at Virginia Tech have published a study in the journal Nature Materials that describes a new process to create lightweight, strong and super elastic 3D printed metallic nanostructured with unprecedented scalability, a full seven orders of magnitude control of arbitrary 3D architectures.

Strikingly, these multiscale metallic materials have displayed super elasticity because of their designed hierarchical 3D architectural arrangement and nanoscale hollow tubes, resulting in more than a 400 percent increase of tensile elasticity over conventional lightweight metals and ceramic foams.

Stanford Researchers ‘Trick’ Human Stem Cells To Regenerate Faster

Posted by in categories: biotech/medical, life extension

Researchers at the Stanford University School of Medicine found a way to trick human embryonic stem cells to become pure populations of any of 12 cell types, including bone, heart muscle and cartilage within days.

Scientists at the Stanford University School of Medicine have identified the sets of biological and chemical signals necessary to quickly and efficiently direct human embryonic stem cells. If successful, researchers could grow pure populations of any of 12 cell types, including bone, heart muscle and cartilage within days rather than the weeks or months previously required.

This is key toward clinically useful regenerative medicine – potentially allowing researchers to generate new beating heart cells to repair damage after a heart attack or to create cartilage or bone to reinvigorate creaky joints or heal from trauma.
