Congress held a meeting today on what NASA’s overall purpose should look like under the next few presidents. But agreement on just what that purpose might be—as witnesses discussed everything from the planned Mars trip to a proposal for a space station hotel—seemed far away.

“If we treated the Air Force like we do NASA, we’d have no flying aircraft. We cannot decide every few years what we want the purpose of the space program to be,” said former NASA administrator Mike Griffin to the House Committee on Science, Space, and Technology this morning.

The Mars mission was a topic of heavy discussion. At one point, Congressman Ed Perlmutter (D-CO) waved a MARS 2033 bumpersticker over his head (whether he brought it with him to the meeting for that specific purpose, or simply has it on him at all times was unclear)—only to have his colleague Congressman Jim Bridenstine (R-OK) snap that perhaps Republicans should print their own Mars 2032 bumper stickers.

In June, a team of programmers will release a ground-breaking new video game called No Man’s Sky, which uses artificial intelligence and procedural generation to self-create an entire cosmos full of planets. Running off 600,000 lines of code, the game creates an artificial galaxy populated by 18,446,744,073,709,551,616 unique planets that you can travel to and explore.

Though this artificial universe is realistic down to the dimensions of a blade of grass, faster than light-speed travel is available in order for players to bridge the unfathomable distances between stars.

Chief architect Sean Murray says No Man’s Sky is different than most games because the landscapes and distances aren’t faked. While most space-based games utilize a skybox that simply rotates between different modalities, No Man’s Sky is virtually limitless and employs real physics.

The quantum world and our world of perception obey different natural laws. Leiden physicists search for the border between both worlds. Now they suggest an upper limit in a study reported in Physical Review Letters.

The laws of the quantum domain do not apply to our everyday lives. We are used to assigning an exact location and time to objects. But fundamental particles can only be described by probability distributions—imagine receiving a traffic ticket for speeding 30 to 250 km/h somewhere between Paris and Berlin, with a probability peak for 140 km/h in Frankfurt.

Boundary

Because the laws are completely different in both worlds, a clear boundary might exist between them. Size and mass could then be used to determine whether an object obeys quantum or macroscopic laws, but the edge of this boundary is elusive. Leiden physicist Tjerk Oosterkamp and his research group have now established established an upper limit for quantum phenomena, closing in on the answer.

Quantum mechanics is littered with different interpretations, but at the core of the entire school of thought is the question of whether there are multiple universes of not. At the core of this idea is the thought, explicated by quantum mechanics, that everything we observe is simply the collapse of all probable scenarios into one specific outcome. Reality, viewed from that perspective, has a very cluttered cutting room floor. But are the things removed from the reel scraps or alternative narratives? There’s the big question.

To answer that question, we need to dive a bit into the mechanisms of the thing. Quantum mechanics says that all particles in the universe can be represented by what are called “wave functions.” A single wave function basically illustrates all the information about a specific system (i.e. a particle), detailing everything from position to velocity. The wave function itself also outlines all the probable outcomes of that system as well.

In other words, the wave function says what a particle is, and — more importantly — what it might being doing any any given time. It represents all possible futures of that particle.

Stunning, truly.

A spectacular new image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from the southern hemisphere at submillimetre wavelengths — between infrared light and radio waves. This is the sharpest such map yet made, and complements those from recent space-based surveys. The pioneering 12-metre APEX telescope allows astronomers to study the cold Universe: gas and dust only a few tens of degrees above absolute zero.

APEX, the Atacama Pathfinder EXperiment telescope, is located at 5100 metres above sea level on the Chajnantor Plateau in Chile’s Atacama region. The ATLASGAL survey took advantage of the unique characteristics of the telescope to provide a detailed view of the distribution of cold dense gas along the plane of the Milky Way galaxy [1]. The new image includes most of the regions of star formation in the southern Milky Way [2].

The new ATLASGAL maps cover an area of sky 140 degrees long and 3 degrees wide, more than four times larger than the first ATLASGAL release [3]. The new maps are also of higher quality, as some areas were re-observed to obtain a more uniform data quality over the whole survey area.

Recent advances in lasers suggest that we may see rockets propelled by light earlier than we had imagined. NASA scientist Philip Lubin and his team are working on a system that would use Earth-based lasers to allow space travel to far-away places in just a fraction of the time needed with current technology.

photonic_propulsion

Using earth based lasers to push along a spacecraft instead of on board hydrocarbon-based fuel could dramatically reduce travel time to Mars, within our lifetime. Currently, it takes five months for a space craft to reach Mars. But, with photonic propulsion, it is likely that small crafts filled with experiments will reach Mars in just 3 days. Large spaceships with astronauts and life support systems will take only one month, which is about 20% of the duration of a current trip.

What’s next? Lubin believes that we may be able to send small crafts with scientific experiments to exoplanets as fast as 5% light speed in, perhaps, 30 years. Eventually, he claims that the technology will carry humans at speeds up to 20% light speed.

How our brains view beauty is also from heredity.

British neurobiologist Semir Zeki says human brains work alike and we have a shared inheritance in the way we perceive beauty Who do you think is beautiful? Apparently all our votes would more or less go to the same person. Wherever we are from in the world, man or woman, Indian or South American, the way we experience beauty is pretty much the same. Because our brains work similarly, and as humans, we have a shared inheritance. Listening to British neurobiologist Semir Zeki is sure to leave one mesmerised about our understanding of the way our brains work.

Zeki, a frontrunner in the fairly nascent field of neuro-aesthetics, was in Bengaluru recently for the British Council’s lecture series “Science and Beyond”. A professor of neuro-aesthetics at the University College London, Zeki specialises in studying the primate visual brain, neural correlates of the experience of love, desire, beauty, within the field of neuro-aesthetics. In his award-winning study conducted across people of various races and cultures, the question he addressed was ‘What are the neural mechanisms that are engaged when you experience beauty?’. “I have not asked anything about the concept of beauty, the nature of beauty or anything like that. All I can tell you is that when you experience beauty, regardless of the source – whether it is visual, musical or mathematical, its correlated activity is in the same part of the brain.

What happens when a patient is in X-Ray and the X-Ray machine blows up like a bomb killing the patient and staff in the room? Well, a new report shows that it can happen where machines are connected to any network (including the net) because a team of hackers showed in their report how they were they hacked several D.C. and Maryland Hospitals medical devices and numerous machines including life support, X-Rays, etc.

Area hospitals are riddled with cybersecurity flaws that could allow attackers to hack into medical devices and kill patients, a team of Baltimore-based researchers has concluded after a two-year investigation.

Hackers at Independent Security Evaluators say they broke into one hospital’s systems remotely to take control of several patient monitors, which would let an attacker disable alarms or display false information.

The team says it strolled into one hospital’s lobby and used an easily accessible kiosk to commandeer computer systems that track medicine delivery and bloodwork requests — more opportunities for malicious hackers to create mayhem.
