Human stem cells give monkey hearts a boost after heart attacks, study says

Posted by in categories: biotech/medical, life extension

Following heart attacks, a handful of monkeys regained some of the pumping ability their hearts had lost after being given human embryonic stem cells, according to a study published Monday in Nature Biotechnology.

Scientists have tried for years to develop a stem cell treatment for heart disease caused by lack of blood flow, which contributed to more than 9.4 million deaths worldwide in 2016, according to the World Health Organization.

“We’re talking about the number one cause of death in the world [for humans],” said study author Dr. Charles Murry, director of the Institute for Stem Cell and Regenerative Medicine at the University of Washington. “And at the moment all of our treatments are … dancing around the root problem, which is that you don’t have enough muscle cells.”

Most highly paid programmers know Python. You can learn it via an online course for just $44

Posted by in category: information science

Contrary to what Silicon Valley portrays, you’ll need more than drive and intelligence to land a high-paying job in the tech world. You’ll need to be well versed in one of the most popular and fastest growing programming languages: Python.

Python made its debut in 1990, and since then it’s been focused and refined by some of the brightest programmers in the industry. That’s resulted in its current status as a multi-faceted, yet beautifully simple language with a wide variety of applications, from interfacing with SQL databases to building websites.

A massive object devastated Uranus a long time ago and it never fully recovered

Posted by in category: cosmology

Our Solar System is a pretty calm place these days, all things considered, but that wasn’t always the case. In the period when the planets were still forming, collisions between various large bodies were common, and they ultimately helped shape the system that we see today. New research shows that Uranus, a chilly, hostile planet with a number of peculiar features, was the victim of a devastating impact during those early years, and it might explain some of the planet’s strange personality.

Uranus moves much differently than the other planets in our Solar System, spinning on its side in comparison to the rest of the worlds in our neighborhood. Astronomers have often wondered just how this happened, but simulations performed by scientists at Durham University’s Institute for Computational Cosmology might have finally produced the answer.

How to See Who’s On Your Wi-Fi

Posted by in categories: cybercrime/malcode, internet

Is your internet moving a little slower than usual? Are you seeing hints of devices you don’t recognize in Windows Explorer, or when you cast media to your TV? If you suspect a neighbor is stealing your Wi-Fi, here’s how to check (and boot them off).

“So someone’s watching Netflix on my internet,” you may say. “What’s the big deal?” Even if you have a little bandwidth to spare, you probably don’t want other people on your network, especially if it’s unsecured. If someone has access to your network, they have access to all the computers on that network, and that’s dangerous. They could access files you’re unknowingly sharing, they could infect you with malware, and in certain situations they could even steal your passwords and other personal information.

As a result, you should take care to make sure each device connected to your network is one you can trust. Thankfully, there are free tools that’ll help you see everyone on your Wi-Fi right now.

Why Particle Physicists Are Excited About This Mysterious Inconsistency

Posted by in categories: mathematics, particle physics

Scientists haven’t conclusively spotted any new particles since the Higgs boson, and that’s got some people worried—there are a ton of other physics puzzles remaining, many of which would require the presence of a new particle to resolve. But recently, there have been some tantalizing clues of new physics, perhaps a new particle, that many scientists are excited about.

There’s a discrepancy between theoretical and experimental calculations of the “muon magnetic moment,” or how strongly the electron’s heavier cousin behaves in a magnetic field. A newer mathematical calculation has made things even more interesting, and some particle physicists are eagerly awaiting the new results from an experiment here in the United States.

Can the gene and cell therapy revolution scale up?

Posted by in categories: biotech/medical, genetics

“I believe gene therapy will become a mainstay in treating, and maybe curing, many of our most devastating and intractable illnesses,” said FDA commissioner Dr Scott Gottlieb after Luxturna’s approval.

As innovative gene and cell therapies continue to make the transition from the laboratory to the clinic, they are bringing with them the promise of truly personalised medicine. The last few years have seen the regulatory approval of the first gene therapies that take a patient’s own immune cells and genetically engineer them to target cancer cells more effectively.

These chimeric antigen receptor T-cell (CAR-T) therapies now represent a rapidly growing field, with Novartis’s Kymriah, the first CAR-T therapy approved by the US Food and Drug Administration (FDA) in August 2017 for the treatment of a rare blood cancer, seen as the tip of the iceberg for this treatment class’ potential. Approval of Kite Pharma’s Yescarta, a CAR-T treatment for certain forms of non-Hodgkin lymphoma, followed just a few months later.

Drug gets body cells to ‘eat’ cancer

Posted by in categories: biotech/medical, engineering

Scientists have designed a special type of drug that helps the body eat and destroy cancerous cells.

The treatment boosts the action of white blood cells, called macrophages, that the immune system uses to gobble up unwanted invaders.

Tests in mice showed the therapy worked for aggressive breast and skin tumours, Nature Biomedical Engineering journal reports.
