Self-Assembling Microrobots Can Be Programmed To Form A Tiny Car

Posted by in category: transportation

Researchers at Germany’s Max Planck Institute for Intelligent Systems have developed a new type of self-assembling mobile micromachine that can be programmed to assemble into different formations — ranging from a tiny car to a miniature rocket. Here’s what’s next for the project.

Sirtuins can be activated by a lack of amino acids or of sugar, or through an increase in NAD. — David Sinclair If you have not heard of #davidsinclair then it is time you have. he is at the forefront of anti aging research and one of my heroes. While we wait for the miracle pills there are alot of thing we can do to help us age better already. #biohacking #biohacker

Researchers develop a lab-grown blood vessel graft from natural polymers with regenerative properties

Posted by in category: biotech/medical

Researchers may be closer to improving the lives of people with coronary artery disease and children born with pediatric congenital cardiovascular defects through the development of a new vascular graft created by Johns Hopkins engineers that takes less than one week to make and has regenerative properties.

Coronary artery disease, or CAD, is the leading cause of death worldwide and people with the disease often require surgery to repair damaged cardiovascular . Bypass surgery, another common intervention, requires removing the damaged tissue and replacing it with from another part of the body, such as the saphenous vein, which runs the length of the leg and is the longest vein in the body. This method puts substantial stress on the body and has other risk factors: it requires patients to have multiple surgical sites, and those in need of the surgery because of plaque build-up may also have plaque accumulation in the grafted vein, causing further complications.

Congenital cardiovascular defects, or CCD, occurs in 1% of live births worldwide, and children born with the condition often undergo repeated surgical reconstruction as they grow. But repeated surgeries reduce the amount of usable vascular tissue for reconstruction and synthetic grafts do not grow as the child grows.

Einstein, Symmetry and the Future of Physics

Posted by in categories: futurism, particle physics

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

Facebook’s digital currency may force central banks to create their own

Posted by in categories: bitcoin, cryptocurrencies, finance

Just a few months ago, Augustín Carstens, the general manager for the Bank for International Settlements (BIS), the so-called central bank for central banks, said his organization saw no value in the potential of central-bank-issued digital currencies. Well, he’s apparently had a change of heart, and the entrance of Facebook and other “big techs” into financial services appears to be the reason.

The news: Carstens told the Financial Times that the BIS is supporting the “many” central banks currently developing or researching digital currencies. “And it might be that it is sooner than we think that there is a market and we need to be able to provide central bank digital currencies,” he said.

The context: Many other central bankers have dismissed cryptocurrencies like Bitcoin, which tend to be volatile and whose most popular use has been speculation. But Facebook’s proposed digital currency, Libra, will be backed by fiat money and designed to maintain a stable value.

Cancer cell’s ‘self eating’ tactic may be its weakness

Posted by in categories: biotech/medical, education, food

Cancer cells use a bizarre strategy to reproduce in a tumor’s low-energy environment; they mutilate their own mitochondria! Researchers at Cold Spring Harbor Laboratory (CSHL) also know how this occurs, offering a promising new target for pancreatic cancer therapies.

Why would a cell want to destroy its own functioning mitochondria? “It may seem pretty counterintuitive,” admits M.D.-Ph. D. student Brinda Alagesan, a member of Dr. David Tuveson’s lab at CSHL.

It’s Hard to Kill Blood Stem Cells—Now We Know Why

Posted by in categories: biotech/medical, life extension

For most of their lives, our hematopoietic stem cells (HSCs)—which produce all of our blood and immune cells—are quiet and inactive. But they also are the toughest cells in the blood system, able to survive exposure to levels of radiation or viral infections that kill most other blood cells.

A new study from researchers in Columbia’s Stem Cell Initiative has discovered how HSCs cheat death, which could lead to new therapies for blood cancers and other diseases related to aging and improve stem cell transplantation.
