Brain signal shows when you understand what you hear

Posted by in category: neuroscience

Researchers have identified a brain signal that indicates whether a person is comprehending what others are saying. The researchers have shown that they can track the signal using relatively inexpensive EEG (electroencephalography) readings taken on a person’s scalp.

During everyday interactions, people routinely speak at rates of 120 to 200 words per minute. For a listener to understand speech at these rates—and not lose track of the conversation—the brain must comprehend the meaning of each of these words very rapidly.

Daily Pill Shows Promise For Alleviating Life-Threatening Peanut Allergies

Posted by in categories: biotech/medical, food, health

Imagine constantly worrying that something you eat is going to cause your throat to swell shut or your heart to stop beating. That’s the reality people with severe peanut allergies must live with every day, because their bodies launch out-of-control immune responses against even a trace of peanut protein.

But now, relief may be on the horizon. A phase 3 clinical trial by pharmaceutical company Aimmune Therapeutics shows that gradual and methodical exposure to purified peanut protein can train the body to drastically tone down the reaction. After one year of daily treatment with the company’s peanut protein-filled capsules, currently called AR101, study participants could safely tolerate 30 times more allergen than they could before the trial began.

The trial included 496 children aged 4 to 17 with allergies so severe that they could not ingest more than 30 milligrams of peanut protein without experiencing moderate to highly dangerous effects. For reference, one peanut contains 250 to 350 milligrams of peanut protein.

Chinese Doctors Are Using Modified T-Cells to Treat Advanced Forms of Cancer

Posted by in categories: biotech/medical, genetics

According to China’s National Central Cancer Registry, Esophageal cancer is one of the most common forms of cancer in China. Like many other types, cancer of the esophagus can be treated with chemotherapy. But, as is also true of other forms of cancer, chemotherapy isn’t always successful. In China, and around the world, there’s a great need for the development of new treatments.

Dr. Shixiu Wu, president of the Hangzhou Cancer Hospital, has tested a somewhat new treatment that takes a patient’s T-cells from the body, genetically edits them to target cancerous cells, then puts the altered cells back. If the process sounds at all familiar, it’s probably because using T-cells in this manner was approved by the U.S. Food and Drug Administration back in August 2017.

The Ongoing Battle Between Quantum and Classical Computers

Posted by in categories: computing, information science, quantum physics

The quest for “quantum supremacy”—unambiguous proof that a quantum computer does something faster than an ordinary computer—has paradoxically led to a boom in quasi-quantum classical algorithms.

GPS Isn’t Very Secure. Here’s Why We Need A Backup

Posted by in categories: cybercrime/malcode, drones, military, mobile phones, satellites

That’s not a lot to you. If your watch is off by 13.7 microseconds, you’ll make it to your important meeting just fine. But it wasn’t so nice for the first-responders in Arizona, Pennsylvania, Connecticut, and Louisiana, whose GPS devices wouldn’t lock with satellites. Nor for the FAA ground transceivers that got fault reports. Nor the Spanish digital TV networks that had receiver issues. Nor the BBC digital radio listeners, whose British broadcast got disrupted. It caused about 12 hours of problems—none too huge, all annoying. But it was a solid case study for what can happen when GPS messes up.

The 24 satellites that keep GPS services running in the US aren’t especially secure; they’re vulnerable to screw-ups, or attacks of the cyber or corporeal kind. And as more countries get closer to having their own fully functional GPS networks, the threat to our own increases. Plus, GPS satellites don’t just enable location and navigation services: They also give ultra-accurate timing measurements to utility grid operators, stock exchanges, data centers, and cell networks. To mess them up is to mess those up. So private companies and the military are coming to terms with the consequences of a malfunction—and they’re working on backups.

The 2016 event was an accidental glitch with an easily identifiable cause—an oops. Harder to deal with are the gotchas. Jamming and spoofing, on a small scale, are both pretty cheap and easy. You can find YouTube videos of mischievous boys jamming drones, and when Pokemon GO users wanted to stay in their parents’ basements, they sent their own phones fake signals saying they were at the Paris mall. Which means countries, and organized hacking groups, definitely can mess with things on a larger scale. Someone can jam a GPS signal, blocking, say, a ship from receiving information from satellites. Or they can spoof a signal, sending a broadcast that looks like a legit hello from a GPS satellite but is actually a haha from the hacker next-door.
