Researchers at Massachusetts Institute of Technology (MIT) have developed what is being called a “snake robot” that’s designed to crawl through the blood vessels in your brain to cure disease.
Scientists at MIT are still testing this method but plan on using this magnetically controlled threadlike robot to surf through the complex vasculature of the human brain in order to deliver clot-reducing therapies to patients who have suffered from aneurysms or strokes.
The team has demonstrated how the robotic thread can be controlled through a life-size silicone replica of the brain’s blood vessels showing how the robot can be controlled just like guiding a thread through the eye of a needle.
Over the past few years, the team has built up expertise in both hydrogels — biocompatible materials made mostly of water — and 3-D-printed magnetically-actuated materials that can be designed to crawl, jump, and even catch a ball, simply by following the direction of a magnet.
“Stroke is the number five cause of death and a leading cause of disability in the United States,” Xuanhe Zhao, an associate professor of mechanical engineering at MIT, said in a statement.
“If acute stroke can be treated within the first 90 minutes or so, patients’ survival rates could increase significantly. If we could design a device to reverse blood vessel blockage within this ‘golden hour,’ we could potentially avoid permanent brain damage. That’s our hope.”
The researchers said they plan in the near future that endovascular surgeries that incorporate existing magnetic technologies, such as pairs of large magnets, the directions of which doctors can manipulate from just outside the operating room, away from the fluoroscope imaging the patient’s brain, or even in an entirely different location.
To say that UC San Diego archaeologist Geoffrey Braswell was surprised to discover a precious jewel in Nim Li Punit in southern Belize is something of an understatement.
“It was like finding the Hope Diamond in Peoria instead of New York,” said Braswell, who led the dig that uncovered a large piece of carved jade once belonging to an ancient Maya king. “We would expect something like it in one of the big cities of the Maya world. Instead, here it was, far from the center,” he said. (more…)
A newly discovered trove of 16 engraved and otherwise modified limestone blocks, created 38,000 years ago, confirms the ancient origins of the pointillist techniques later adopted by 19th and 20th century artists such as Georges Seurat, Vincent Van Gogh, Camille Pissarro, and Roy Lichtenstein.
Archaeologists from Israel’s Hebrew University have declared they found “one of the most exciting archaeological discoveries in 60 years.”
Lying in the old Judean desert just down the dusty cliff side, a cave was discovered with broken ancient storage jars, fragments of a scroll wrapping, and a leather tying string. It is being dubbed the 12th cave that once housed Dead Sea Scrolls. (more…)
Researchers from Arizona State University (ASU) have found that the Southwest Native Americans had advanced geometry skills that enabled them to build sophisticated architectural complexes. They were so good in fact, they could be called Pythagoreans.
These findings represent the first potential quantitative evidence of knowledge of advanced geometrical constructs in a prehistoric North American society, which is particularly remarkable given that the ancestral Pueblo peoples had no written language or number system.
Over the last decade, there have been many people around the world who have been reporting and documenting what are known as chemtrails. These chemtrails are said to be manmade clouds from planes that look like contrails initially, but they are poisonous chemicals being sprayed in the air that are much thicker, extend across the sky and are often laid down in varying patterns of Xs, tick-tack-toe grids etc.
A recent international survey of 3015 people had shown that 17% of people believe in the existence of a secret large-scale government chemtrail program to be true or partly true. (more…)
There is a growing and disturbing trend of anti-intellectual elitism in American culture. It’s the dismissal of science, the arts, and humanities and their replacement by entertainment, self-righteousness, ignorance, and deliberate gullibility.
Susan Jacoby, author of The Age of American Unreason, says in an article in theWashington Post, “Dumbness, to paraphrase the late senator Daniel Patrick Moynihan, has been steadily defined downward for several decades, by a combination of heretofore irresistible forces. These include the triumph of video culture over print culture; a disjunction between Americans’ rising level of formal education and their shaky grasp of basic geography, science and history; and the fusion of anti-rationalism with anti-intellectualism.” (more…)
In a 1962 address at Rice University, Houston, Texas, former United States President John F. Kennedy addressed the nation’s efforts in space exploration. In his speech the President famously stated, “We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard.”
A man has not touched the moon since 1972. However, today manned missions to the moon are the talk of the science community and missions are being planned by an international team of scientists who are planning a permanent moon colony in the next five to seven years — for just $10 billion. (more…)
There is a tremendous amount of interest in Nefertiti, who died in the 14th Century B.C., and was known as the Ruler of the Nile and Daughter of Gods. She was an Egyptian queen and the Great Royal Wife of Akhenaten, an Egyptian Pharaoh.
Nefertiti and her husband were known for a religious revolution, in which they worshiped one god only, Aten, or the sun disc. She is also thought thought to be Tutankhamun‘s stepmother.
Nefertiti is well known for her elegant beauty. Her image, and bust have been an icon for many women and for many modern cosmetic lines.
This past October, a pair of artists, Al-Badri and Nelles, secretly scanned the head of Queen Nefertiti at the Neues Museum in Berlin without permission of the Museum. (more…)
