This 3D-Printed Bone Implant Dissolves In Body

In a major step towards improving surgeries after head or face injuries, scientists have developed a new type of 3D-printed polymeric bone implants that can survive in the body for long periods and be subsequently replaced with natural bone tissue in the body. The implant is coarctate and thus shielded from the mechanical impact of surgery, and it ‘unfolds’ at a certain temperature during the surgery. Researcher said that the implant could be 3D printed at the selected dimensions, compressed twice in protective, biodegradable shelling, heated during the surgery and eventually fix into the renovated area of bone tissue without using blocking devices and fasteners used in transplantology. Researcher has applied the shape memory effect in a polymeric composite material based on polylactide. Researcher have developed a technology stacking multi-potent mesenchymal stromal cells, a bioengineering structure isolated from a patient’s bone marrow, which stimulates the formation of blood vessels and tissue inside the implant, thus optimizing the process of survival and increasing the efficiency of transplantation.

Soon, Screens That Remotely Charge Phone

A flat screen panel that resembles a TV on your living room wall could one day remotely charge smartphones and tablets within its line of sight, making dead batteries a thing of the past, according to new research. Scientists said that the technology already exists to build such a system. There is an enormous demand for alternatives to today’s clunky charging pads and cumbersome cables, which restrict the mobility of a smartphone or a mobility of a smartphone or a tablet. The ability of safely direct focused beams of microwave energy to charge specific devices, while avoiding unwanted exposure to people, pets and other objects, is a game changer for wireless power.

Baby Is 'Born' Twice After Miracle Surgery In US

A baby girl in the US was successfully ‘born’ for the second time, after being taken out of her mother’s womb for 20 minutes at 23 weeks of pregnancy for a groundbreaking surgery to save her life. The baby was delivered by C section after 12 weeks. Margaret Boemer, from the US, was 16 weeks pregnant when she was told that her baby had a sacrococcygeal teratoma – a tumour grows from the baby’s tailbone before birth. This is the most common tumour doctors see in a newborn. Even though it’s the most common they see, it was still a pretty rare. According to doctor, the tumour feeds on blood flow from the baby, competing with the baby as they both are trying to grow. In some instances, the tumour wins and the heart just can’t keep up and the heart goes into failure and the baby dies. At 23 weeks, the tumour was shutting her heart down and causing her to go into cardiac failure, so it was a choice of allowing the tumour to take over her body or giving her a chance at life. An emergency surgery was performed at 23 weeks and 5 days of pregnancy, when the tumour was nearly larger than the foetus. The tumour was so large a huge incision was needed to reach it, so the baby had to be taken out of the womb. The team successfully removed the bulk of the tumour. When they finished their operation, the surgeon placed the baby back inside the womb and sewed her mother’s uterus shut. After another 12 weeks Lynlee Hope was born for the second time via C-section in June this year.

Self-Driving Truck Makes First Delivery: 45,000 Cans Of Beer

In the first real-world commercial use of autonomous trucking, some 45,000 cans of Budweiser beer arrived late last week of October to a warehouse after travelling over 120 highways miles (193 km) in a self-driving truck with no driver at the wheel, executives from Uber and Anheuser Busch said. Otto, the self-driving truck subsidiary of Uber, shipped a truckload of Budweiser from Fort Collins, Colorado Springs on 20 October with the driver monitoring from the truck’s sleeper berth for entire two hour journey, Otto’s co-founder Lior Ron and Anheuser-Busch’s senior director of logistics strategy, James Sembrot, said. The truck made the trip using only its panoply of cameras, radar and sensor to read the road. The early morning drive at an average speed of 55 mph (89kmph) marks what the two executives said was the first revenue generating load transported via autonomous truck. Otto was paid the market rate of $470 for the job using one of its trucks outfitted with the new technology. Otto and Anheuser-Busch enlisted the support of the state of Colorado before the drive, and the state patrol monitored it, although Colorado and most other US state do not expressly prohibit self driving trucks. The only time the truck driver delivering the beer took to the wheel was while driving on and off the highway ramp. Transportation experts predict the earliest applications of autonomous technology will be in self-driving trucks, not cars. The technology is best suited to the relative predictability of long hauls on highways, rather than busy city streets with many distractions. Another Silicon Valley company, Peloton Technology, is testing driver assisted “platooning” in which trucks communicate, travelling in close formation to reduce drag and save on fuel, while increasing safety. Otto, co-founder by Google car and map project veterans Anthony Levandowski and Ron, was acquired in August by Uber, which is trying to advance self-driving technology in its ride services business. Ron told Reuters that Otto plans to involve more commercial partners and independent drivers who will use the technology, designed to increase safety and decrease costs as the truck is able to be operated 24 hours a day and 7 days a week. The biggest cost savings for the trucking industry will eventually come from eliminating the driver entirely, but Ron said drivers would remain inside the trucks “for the foreseeable future.”

A Robot Tutor That Encourages Bored Students To Learn

Scientists have developed a new robot teacher that can detect whether children are distracted in class and accordingly respond to encourage them. Researchers at the Department of Artificial Intelligence in Madrid have developed an integrated computational architecture (Artie) for use with software applications in schools. The main goal of this work was to design a system that can detect the emotional state of primary school children interacting with educational software and make pedagogic interventions with a robot tutor that can ultimately improve the learning experience. Rather than focusing on specific emotions, the researchers first identified three cognitive states (concentrating, distracted and inactive) known to influence the course of learning. Keyboard strokes and mouse actions of children using educational software were used to predict which of these cognitive states the child is experiencing and subsequently linked to an algorithm that chooses the correct form of pedagogic intervention. These could be words and gestures of encouragement or attempts to raise interest and motivation for a specific learning objective, all of which can be delivered by a robot tutor.

A Way To Spot False FB Posts, Tweets

Scientists have developed a new method for spotting people who post false reviews or tweets from multiple social media accounts to espouse opinions. Researchers from the University of Texas have devised a statistical method that analyses multiple writing samples – a practice known as “astroturfing”. They found that it was challenging for authors to completely conceal their writing style in their text. Based on word choice, punctuation and context, the method was able to detect whether one person or multiple people were responsible for the samples. Researchers used writhing samples from online commenter’s on news websites and discovered that many people espousing their opinions online were all linked to a few singular writers with multiple accounts. Astroturfing is legal, but it is questionable ethically. The practice has been used by businesses to manipulate social media users by having one paid associate posts false reviews on sites about products for sale. Politicians have also been accused of astroturfing to create the illusion of public support for a campaign. Former US President George Bush, Hillary Clinton and Donald Trump have been accused of astroturfing.

Onion Compound May Treat Ovarian Cancer

A natural compound isolated from onions may help ovarian cancer, a new study has claimed. Researchers from Kumamoto University in Japan studied the effects of onionin A (ONA) on a preclinical model of epithelial ovarian cancer (EOC) both in vivo and in vitro. Previously, researchers found that ONA suppressed pro-tumour activation of host myeloid cells. According to WHO, EOC is the most common type ovarian cancer and has a five year survival rate of about 40%. The group’s in vitro experiments showed that EOCs which usually proliferate in the presence of pro tumour M2 macrophages, showed inhibited growth after introduction of ONA. This was thought to be due to ONA influence of STAT3, a transcription factor known to be involved in both M2 polarization and cancer cell proliferation. The team also found that ONA inhibited the pro-tumour function of myeloid-derived suppressor cells, which are associated with the suppression of the anti-tumour immune response of host lymphocytes, by using preclinical sarcoma model. ONA was also found to enhance the effects of anti-cancer drugs by strengthening their anti-proliferation capabilities.
