The invisible and the non-existent look very much alike
The US Department of Homeland Security is developing a system designed to detect "hostile thoughts" in people walking through border posts, airports and public places. The DHS says recent tests prove it works.'Pre-crime' detector shows promise
A 2005 DARPA report... proposes to "image through multiple walls and even penetrate whole buildings using distributed sensors on or around buildings," with UAVs assisting ground forces. A 2007 Army Research Lab study explores the ability of ground sensors, working with UAVs, to capture "images from different angles," thereby providing "intelligence on the configuration, content, and human presence inside enclosed areas (buildings)."Nowhere To Hide - Killer drones that can see through walls

Phagocytosis is the cellular process of engulfing solid particles by the cell membrane... in the immune system it is a major mechanism used to remove pathogens and cell debris.

Chemotaxis is the phenomenon in which bodily cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.

MEDUSA (Mob Excess Deterrent Using Silent Audio)
The device – dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) – exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognisable sounds...Microwave ray gun controls crowds with noise
MEDUSA involves a microwave auditory effect "loud" enough to cause discomfort or even incapacitation. Sadovnik says that normal audio safety limits do not apply since the sound does not enter through the eardrums.

An Elephant Crackup
The elephants of decimated herds, especially orphans who’ve watched the death of their parents and elders from poaching and culling, exhibit behavior typically associated with post-traumatic stress disorder and other trauma-related disorders in humans: abnormal startle response, unpredictable asocial behavior, inattentive mothering and hyperaggression...In July of last year, officials in Pilanesberg shot three young male elephants who were responsible for the killings of 63 rhinos, as well as attacks on people in safari vehicles. In Addo Elephant National Park, also in South Africa, up to 90 percent of male elephant deaths are now attributable to other male elephants, compared with a rate of 6 percent in more stable elephant communities.An Elephant Crackup?

4.6 Billion Years of Love
If the Great Filter is ahead of us, we have still to confront it. If it is true that almost all intelligent species go extinct before they master the technology for space colonization, then we must expect that our own species will, too, since we have no reason to think that we will be any luckier than other species. If the Great Filter is ahead of us, we must relinquish all hope of ever colonizing the galaxy, and we must fear that our adventure will end soon--or, at any rate, prematurely. Therefore, we had better hope that the Great Filter is behind us.Where are they?

Neural Predictors

By watching how different neural circuits light up or go dark during the buying process, the researchers found they could predict whether a person would end up purchasing a product or passing it up. They concluded, after further analysis of the results, that "the ability of brain activation to predict purchasing would generalise to other purchasing scenarios".Neuromarketing could make mind reading the ad-man's ultimate tool

Was I going nuts? Nope. I had simply encountered a new advertising medium: hypersonic sound. It broadcasts audio in a focused beam, so that only a person standing directly in its path hears the message.

We're not gonna make it, are we? People, I mean.
ALICE: Who created you?
Jabberwacky: My mother gave birth to me. Is that what you mean?
A: Jabberwacky, I meant exactly what I said.
J: Do you believe in God?
A: Of course I believe in God.
J: Why do you believe in God?
A: The Bible tells us to believe in God.
J: That’s circular reasoning.
A: I’m glad we have that all cleared up.

Baka wa shinanakya naoranai

Haishaku, a critter found in the upper lungs, has a nose that opens directly into its chest. People infected with Haishaku hate pleasant smells and foul smells, but are fond of strong, fishy smells. Other symptoms include extreme sadness and a craving for spicy food.Mythical 16th-century disease critters

Fish

Electrodes sense "bioelectronic signals" emitted whenever the fish inhale through their gills. The information is fed into a computer programmed to recognise their normal respiration rates.
A screen displays the information. If the computer ever detects that at least five fish - a majority of those on guard - are breathing abnormally and are in distress, it will automatically trigger an alarm and order gates to close, shutting off the flow in canals carrying water to Sydney.
