A new three-dimensional map of part of the universe, created by a massive international team of researchers, is refuting the idea that Einstein’s theory of general relativity could be breaking down in the faraway universe, according to a new report in the Publications of the Astronomical Society of Japan.

“We tested the theory of general relativity further than anyone else ever has. It’s a privilege to be able to publish our results 100 years after Einstein proposed his theory,” study author Teppei Okumura, an astrophysicist from The University of Tokyo, said in a news release.

Very promising. I hope within the next 10 years that Glioblastoma is eradicated.

A team from the International School for Advanced Studies (SISSA) in Trieste has obtained very promising results by applying gene therapy to glioblastoma. Tests in vitro and in vivo on mice provided very clear-cut results, and modelling demonstrates that the treatment targets at least six different points of tumour metabolism. Gene therapy, a technique that selectively attacks a tumour, might provide hope in the fight against this type of deadly cancer, for which surgery is practically impossible and chemo- and radiotherapy are ineffective against very aggressive recurrences. The study was published in the journal Oncotarget.

Only a few days ago, the press (especially in English-speaking countries) enthusiastically announced the publication of a study that described in great detail the genetics of breast cancer, a discovery that according to many marks a breakthrough in the battle against this cancer. This kind of news confirms the impression that in the near future the war against cancer will be fought on the battlefields of genetics. Italy too, is working on this front. At SISSA, for example, where Antonello Mallamaci and his group have just published highly promising results on the application of gene therapy against glioblastomas, a family of brain tumours among the most common and aggressive. A diagnosis of glioblastoma is literally equal to a very imminent death sentence: “surgery is rarely curative, as these tumours insinuate themselves in healthy tissues, and also chemo- and radiotherapy have little effectiveness.

Quantum future discussed at London’s Royal Society Conference.

By Tushna Commissariat

Not a week goes by here at Physics World that we don’t cover some advance in quantum mechanics – be it another step towards quantum computing or error correction, or a new type of quantum sensor, or another basic principle being verified and tested at new scales. While each advance may not always be a breakthrough, it is fair to say that the field has grown by leaps and bound in the last 20 years or so. Indeed, it has seen at least two “revolutions” since it first began and is now poised on the brink of a third, as scientific groups and companies around the world race to build the first quantum computer.

The precise measurement of position has a distinguished place in physics; about a 100 years ago, debate surrounding the atomic hypothesis was settled by the careful observation of Brownian motion. Today, researchers in the field of cavity quantum optomechanics hope to settle similar fundamental questions.

Singaporean scientists have developed a method for generating stem cells that only requires a single drop of blood.

For my Precision Medicine partners — nice.

Despite eclectic ways of delivering insulin to control blood glucose level in people with type 1 diabetes (T1D), no approach precisely replicates what happens in the body. Gene therapy may hold the answer.

T1D is usually autoimmune, with inherited risk factors such as certain HLA haplotypes contributing to, but not directly causing, the condition. A clever use of gene therapy is to commandeer liver cells to step in for the pancreatic beta cells that autoimmunity destroys.

It is fascinating to think that in 100 billion years a new civilization might look into the sky and have all the evidence to think their galaxy is the entire universe.

Even with a perfect understanding of science and a perfect execution of technologies, there are some things we’ll never reach.

Imagine this: you accidentally swallowed a battery (!), and to get it out, you need to take a pill that turns into a robot. Researchers from MIT, the University of Sheffield and the Tokyo Institute of Technology have developed a new kind of origami robot that transforms into a microsurgeon inside your stomach. They squished the accordion-like robot made of dried pig intestine inside a pill, which the stomach acid dissolves. A magnet embedded in the middle allows you or a medical practitioner to control the microsurgeon from the outside using another magnet. It also picks up the battery or other objects stuck inside your stomach.

This new design is a follow up to an older origami robot also developed by a team headed by MIT CSAIL director Daniela Rus. It has a completely different design and propels itself by using its corners that can stick to the stomach’s surface. The team decided to focus on battery retrieval, because people swallow 3,500 button batteries in the US alone. While they can be digested normally, they sometimes burn people’s stomach and esophagus linings. This robot can easily fish them out of one’s organs before that happens. Besides origami surgeons, Rus-led teams created a plethora of other cool stuff in the past, including robots that can assemble themselves in the oven.
