In the mid-1960s the Elizabethan morality play space western known as "Star Trek" debuted and series creator Gene Roddenberry was cagey about when exactly it took place (thus the reason to use 'star dates'), but it had to have been in the 23rd century if later writers were getting their information relayed correctly.  Regardless of the exact dates of their five year mission, the public was energized by the future - and the gadgets it contained.

Portable computers were completely believable and wireless communications already existed. A fax machine was clearly on the horizon, since the teletype had already existed since 1915 and a fax just required a phone line - but medical diagnosis was not even close to "Star Trek"'s future yet.

According to some papers, human echolocation is another "sense," working in tandem with hearing and touch to deliver information to people with visual impairment.

A new paper adds evidence for the vision-like qualities of echolocation in blind echolocators - by wrongly judging how heavy objects of different sizes felt.

The experiment, conducted by psychologist Gavin Buckingham of Heriot-Watt University in Scotland and colleagues at the Brain and Mind Institute at Western University in Canada, demonstrated that echolocators experience a "size-weight illusion" when they use their echolocation to get a sense of how big objects are, in just the same way as sighted people do when using their normal vision.

The "Basel-Gasfabrik" Celtic settlement, at the present day site of Novartis, was inhabited around 100 B.C. and is one of the most significant Celtic sites in Central Europe.

A team recently examined samples from the backfill of 2000 year-old storage and cellar pits from the Iron Age and found the durable eggs of intestinal parasites like roundworms (Ascaris sp.), whipworms, (Trichuris sp.) and liver flukes (Fasciola sp.).

Women frequently experience more severe allergic reactions than men but it has been unclear why. Yet that disparity is more reason why gender balance in studies and trials makes sense.

Anaphylaxis is an allergic reaction triggered by food, medication or insect stings and bites. Immune cells, particularly mast cells, release enzymes that cause tissues to swell and blood vessels to widen. As a result, skin may flush or develop a rash, and in extreme cases, breathing difficulties, shock or heart attack may occur. Clinical studies have shown that women tend to experience anaphylaxis more frequently than men, but why this difference exists is unclear.

When people spend time interacting with their smartphones, it is changing the way their thumbs and brains work together, according to a report in Current Biology.

More touchscreen use in the recent past translates directly into greater brain activity when the thumbs and other fingertips are touched, the study found. And smartphones have become a good way to explore the everyday plasticity of the human brain.

Not only are people suddenly using their fingertips, and especially their thumbs, in a new way, but many are doing it an awful lot, day after day. Our phones are also keeping track of our digital histories to provide a readymade source of data on those behaviors. 

10 percent of the world's ants are close relatives, belong to just one genus out of 323. That genus is  called Pheidole. Pheidole fill niches in ecosystems ranging from rainforests to deserts.
