Nanoparticles carry drug duo into the brain to fight cancer

Posted by in categories: biotech/medical, nanotechnology, neuroscience

Glioblastoma is one of the most deadly forms of cancer. Affecting the brain, those unlucky enough to receive a diagnosis don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors.

The MIT nanoparticles are liposomes, fatty droplets that can carry one drug on the inside and another in the outer layer. On the inside, the particles were loaded with a common chemotherapy drug called temozolomide, while the outer shell contained a more experimental substance known as JQ-1.

Exoskeleton Technologies

Posted by in category: cyborgs

Exoskeleton technologies can bring new capabilities to fighting forces and improve endurance and safety in industrial settings. Lockheed Martin continues refinement of next-generation industrial products with primary focus on powered exoskeletons. Lockheed Martin’s new lower-body exoskeleton has demonstrated to increase mobility. By reducing the effort in walking and climbing this technology can literally help soldiers and first responders go the extra mile while carrying mission-essential equipment.

Here’s how China is challenging the U.S. and European brain initiatives

Posted by in categories: government, neuroscience

The nascent China Brain Project took another step toward reality last week with the launch of the Shanghai Research Center for Brain Science and Brain-Inspired Intelligence. The new center and its Beijing counterpart, launched 2 months ago, are expected to become part of an ambitious national effort to bring China to the forefront of neuroscience. But details of that 15-year project—expected to rival similar U.S. and EU efforts in scale and ambition—are still being worked out, 2 years after the government made it a priority.

New research centers move 15-year project closer to reality.

Measles makes alarming return to Europe and the Americas

Posted by in categories: biotech/medical, economics, health, neuroscience

Why it matters: Measles is a killer disease. It’s estimated that more than 2 million children a year died from measles in the 1980s, but due to global vaccine programs (including Gavi, the Vaccine Alliance launched in 2000), that number has been brought under 70,000 cases. The return of measles to Europe and the Americas could suggest that some of our vaccine successes could be reversing or unraveling. In the case of Venezuela, measles outbreaks are mostly due to the effect of broad economic problems on its health care system, but for Europe and the U.S. measles outbreaks show the effects of powerful and well-organized anti-vaccine movements.

What’s next: Vaccines do not cause autism, but more advocacy is needed to counteract the false claims of anti-vaccine groups. In April 2018, the European Commission proposed activities to strengthen the EU’s capacity to vaccinate its population and address what some call “vaccine hesitancy.” In the U.S., however, there are still 18 states that allow non-medical vaccine exemptions linked to personal or philosophical beliefs.

Peter Hotez is a professor and dean of the National School of Tropical Medicine at Baylor College of Medicine, where he is also director of the Texas Children’s Hospital Center for Vaccine Development, and the author of “Vaccines Did Not Cause Rachel’s Autism.”

Swallowable ‘bacteria on a chip’ could help diagnose colon cancer, bowel disorders and gut ulcers

Posted by in categories: biotech/medical, computing, genetics, health

Unlike other ingestible chips, this new version by MIT contains millions of genetically engineered living cells to act as sensors, designed to light up when they detect bleeding.

It’s the latest advance in a growing field of sensors that can be swallowed or worn to monitor our health.

Pills equipped with cameras, thermometers and acidity gauges already look for disease and track digestion.

Does a black hole ever die?

Posted by in categories: cosmology, futurism

Astronomer Misty Bentz would like you to know that black holes don’t suck. “They’re not cosmic vacuum cleaners going around and sucking everything in,” she says. “They just use gravity the same way everything else does.”

Instead of a cosmic drinking straw, a black hole is a place in the universe that is so massive and dense that anything caught in its significant gravitational pull is unable to escape.

Black holes have been in the news a lot lately, from the swarm found near the supermassive black hole at the center of our galaxy, to the fastest-growing black hole ever observed, which ingests the equivalent of the mass of our Sun every two days, to the most distant black hole ever detected, dating to the dawn of the universe. From their inception to their potential demise far in the future, black holes are a fascinating part of our universe. Here’s their story as we understand it now, from start to finish.

Self-Driving Cars Have a Big Problem: Americans Don’t Trust Them

Posted by in categories: Elon Musk, robotics/AI

Self-driving cars have plenty of benefits — but the American public still doesn’t trust them. A report from the American Automobile Association released Tuesday shows that 73 percent of drivers would be too afraid to ride in a self-driving car, a marked jump from the 63 percent reported late last year, with millennial distrust jumping from 49 percent to 64 percent over the same period.

The results of the survey come despite autonomous-vehicle makers reporting strong signs of progress. Waymo, which started life as Google’s self-driving car project, announced in March that it’s accumulated over 5 billion miles in virtual driving and 5 million miles in real-world driving, after opening its autonomous minivan service to the public last year. Tesla CEO Elon Musk, who said in February he’s “pretty excited about how much progress we’re making on the neural net front,” has predicted autonomous driving for existing vehicles could surface in a matter of months. Companies like Aurora are predicting their systems could hit the markets in 2021.

Using the K computer, scientists predict exotic “di-Omega” particle

Posted by in categories: computing, cosmology, mathematics, particle physics, quantum physics

Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based Science and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program, together with colleagues from a number of universities, have predicted a new type of “dibaryon”—a particle that contains six quarks instead of the usual three. Studying how these elements form could help scientists understand the interactions among elementary particles in extreme environments such as the interiors of neutron stars or the early universe moments after the Big Bang.

Particles known as “baryons”—principally protons and neutrons—are composed of three quarks bound tightly together, with their charge depending on the “color” of the quarks that make them up. A dibaryon is essentially a system with two baryons. There is one known dibaryon in nature—deuteron, a deuterium (or heavy-hydrogen) nucleus that contains a proton and a that are very lightly bound. Scientists have long wondered whether there could be other types of dibaryons. Despite searches, no other dibaryon has been found.

The group, in work published in Physical Review Letters, has now used powerful theoretical and computational tools to predict the existence of a “most strange” dibaryon, made up of two “Omega baryons” that contain three strange quarks each. They named it “di-Omega”. The group also suggested a way to look for these strange through experiments with heavy ion collisions planned in Europe and Japan.
