Amazon has unveiled its self-piloting Prime Air drone that the tech giant says will soon be used to fly packages directly to customers’ doors. Amazon will be conducting test delivery flights in the months ahead. NBC’s Tom Costello reports for TODAY. June 6, 2019.
NASA is going to be testing a new precision landing system designed for use on the tough terrain of the moon and Mars for the first time during an upcoming mission of Blue Origin’s New Shepard reusable suborbital rocket. The “Safe and Precise Landing – Integrated Capabilities Evolution” (SPLICE) system is made up of a number of lasers, an optical camera and a computer to take all the data collected by the sensors and process it using advanced algorithms, and it works by spotting potential hazards, and adjusting landing parameters on the fly to ensure a safe touchdown.
SPLICE will get a real-world test of three of its four primary subsystems during a New Shepard mission to be flown relatively soon. The Jeff Bezos –founded company typically returns its first-stage booster to Earth after making its trip to the very edge of space, but on this test of SPLICE, NASA’s automated landing technology will be operating on board the vehicle the same way they would when approaching the surface of the moon or Mars. The elements tested will include “terrain relative navigation,” Doppler radar and SPLICE’s descent and landing computer, while a fourth major system — lidar-based hazard detection — will be tested on future planned flights.
Currently, NASA already uses automated landing for its robotic exploration craft on the surface of other planets, including the Perseverance rover headed to Mars. But a lot of work goes into selecting a landing zone with a large area of unobstructed ground that’s free of any potential hazards in order to ensure a safe touchdown. Existing systems can make some adjustments, but they’re relatively limited in that regard.
Summary: Cortical representations for the sounds and meanings of new words learned form within an hour or two following exposure.

How much time does a brain need to learn a new word? A team of Skoltech researchers and their colleagues monitored changes in brain activity associated with learning new words and found that cortical representations of the sound and meaning of these words may form in just 1 to 2 hours after exposure without any night’s sleep consolidation, as earlier research suggested. This research has implications for diagnosing speech disorders and improving the efficiency of learning. The paper was published in the journal Frontiers in Neuroscience.

Ira Pastor Comments:
Getting blood drawn is not a fun activity for many. It can be scary for some (especially if you have children); it can be painful for others (especially where frequent blood draws are required).
Studies show that a remarkable 20% of the population has some degree of fear of needles or injections, and 10% within that number suffer from what is known as Trypanophobia (a psychological term for people with an extreme fear of medical procedures involving injections or hypodermic needles), who on top of their anxiety, completely avoid necessary tests and treatment.
In addition to this, it is estimated that needles injure healthcare workers more than 2 million times a year in accidents, with potentially dangerous and deadly outcomes.
Drawing blood is likely the most common invasive medical procedure, with an estimated half a billion a year conducted in U.S. hospitals alone, and two to three times this number across all hospitals worldwide annually.
