A robot in China performed dental surgery on a living person

Going to the dentist is a scary experience for many, but obviously not for the brave person who volunteered to undergo oral surgery performed by a robot. The procedure took place in China, where the robotic dentist successfully implanted a pair of teeth into patient's mouth. No human took an active role in the surgery, according to a local report.

Columbia Engineering researchers make soft robotics breakthrough with new artificial muscle

Researchers at Columbia Engineering have made a breakthrough in soft robotics that is said to have solved a long standing issue in creating untethered soft robots. The goal of these soft robots is to mimic the action and movements of natural biological systems. The research team was led by Hod Lipson, a professor of mechanical engineering. The team developed a 3D printable synthetic soft muscle.

Neanderthal remains of 8-year-old boy reveal secrets of the large brain

Neanderthal remains of 8-year-old boy reveal secrets of the large brain

The remains of a young Neanderthal boy are helping shed light on how Neanderthals developed such large brains (larger than that of modern humans, in fact). According to the study, these larger brains were likely due to longer growth periods. Such a conclusion was made by analyzing the largely complete and well-preserved skeletal remains of a Neanderthal child estimated to have been 7 or 8 at the time of death.

Scientists edit DNA in human embryos to aid the infertile

Scientists edit DNA in human embryos to aid the infertile

A team of scientists have announced that they have successfully edited DNA in human embryos and that editing has allowed them to make what they call a fundamental discovery about the earliest days of human development. The researchers modified a key gene in very early-stage embryos that is said to be crucial to allowing the embryo to develop normally.

This ancient giant frog had powerful jaws and ate small dinosaurs

This ancient giant frog had powerful jaws and ate small dinosaurs

The ancient (and now extinct) frog known as the Beelzebufo had powerful jaws, ones far more powerful than ordinary frogs that exist today, and it feasted on creatures that included small dinosaurs and crocodiles. Such information comes from a new study analyzing the jaw strength of this extinct frog, which lived about 68 million years ago.

Ocean exposed by Larsen C ice shelf is now a protected area

Ocean exposed by Larsen C ice shelf is now a protected area

Remember the huge chunk of ice that finally broke free in Antarctica? The British Antarctic Survey has just announced a new international agreement that is lending protection to the part of the ocean left exposed by the calving event. According to the research council, the agreement is now in place and will help ensure that researchers are able to research the marine conditions exposed for the first time in about 120,000 years.

AI and non-invasive MRI can diagnose Alzheimer’s disease long before doctors can

AI and non-invasive MRI can diagnose Alzheimer’s disease long before doctors can

A pair of researchers from the University of Bari in Italy called Nicola Amoroso and Marianna La Rocca and a team of colleagues have developed a new machine-learning algorithm that is able to help diagnose Alzheimer's disease up to nine years before doctors can diagnose the condition. The system the researchers have developed is also able to discern structural changes in the brain that are caused by Alzheimer's.

Bacteria caught eating chemo drugs meant for cancerous tumors

Bacteria caught eating chemo drugs meant for cancerous tumors

Bacteria has been spotted 'eating' chemotherapy drugs intended for treating cancerous tumors, potentially opening the door for more effective cancer treatments in the future. According to a new study, certain types of bacteria may exist in the vicinity of cancer cells, devouring the chemo drugs that would otherwise combat the cancerous tumors that result. This prevents adequate levels of these drugs from reaching the cancerous cells, resulting in a sort of chemo-resistant cancer.

Three Occultations, all today (with and without the magic)

Three Occultations, all today (with and without the magic)

This week we're set to witness one real celestial event while another is said to be beginning to "end the world as we know it." Of course one of these events is real, while the other is complete nonsense. The first event begins today, and it has to do with the position of our Moon and three other planets within our Solar System. This event is a triple-occultation.

MIT invents fabrication method that allows one vaccine injection to carry multiple doses

MIT invents fabrication method that allows one vaccine injection to carry multiple doses

Engineers from MIT have created a new 3D fabrication method that is able to generate a new type of drug carrying particle that could allow the delivery of medical vaccines that can deliver more than one dose. That means the potential for vaccines that people normally have to come in for a second dose, meaning another shot, could be delivered with a single injection.

Mars isolation test will end this weekend after 8 months

Mars isolation test will end this weekend after 8 months

Back in January, we reported that a crew was going to spend 8 months living in isolation in a location that simulated the Mars environment. This isolation is a test ahead of future missions to Mars, where humans will spend large amounts of time in cramped quarters with a small group of other people. This crew is scheduled to exit their accommodations this upcoming Sunday.

Micro-needle skin patch is a futuristic treatment for diabetes and obesity

Micro-needle skin patch is a futuristic treatment for diabetes and obesity

Researchers have detailed a new potential treatment option for diabetes and obesity, one that requires wearing a patch containing 'microneedles.' These micro-needles are exactly they sound like -- very small needles that pierce the skin to deliver medication to the patient. The patch was created by researchers with the University of North Carolina and Columbia University Medical Center.
