Water is scarce on Mars and it costs $2 million to send a single brick to the Red Planet, according to estimates. But astronauts can simply make their own concrete on-site using Martian dust and their own blood, according to findings published this month in the journal Materials Today Bio...
The blood-and-dust mixture alone is equivalent to concrete, but researchers say it becomes even stronger when human urea is added to the mix...
Roberts and his team say that animal blood could eventually replace human blood in Martian construction projects, but that would only happen after we send cows to Mars.

This invention relates to new and useful improvements in breast supporters for women and aims to provide simple, inexpensive and efficient means whereby large and flabby breasts of women, especially of the buxom type, may be so supported as to assume a firm and solid condition. Furthermore, the use of my present device will prevent the flapping of the breasts while walking, which always is an undesired feature in women afflicted with breasts of unusual proportions.

Schiffman says he was surprised to discover that television improved the drivers' concentration. He believed the moving and talking images enticed the drivers to keep their eyes on the road as they peeked at the projections in front of them.

In addition, the images kept the drivers alert, he said, stimulating their sympathetic nervous system, or fight-or-flight response.

Generally, the banana shaped writing device is a pencil that resembled a banana wherein the banana is peeled to reveal the lead. The banana shaped writing device allows the users to access additional lead when it gets too short or dull by peeling the banana layers. It enables children and even adults to stand out by using such a unique pencil. The device includes a cushioned inside that provides comfort to users, especially left-handed users. The present invention assists children that are beginning to learn how to write remember correct finger position.

Man has understood the vital interest he had in developing the means to go fast, long and far; for this purpose, he enslaved animals to his use, he acquired science, in particular mechanical science, and he used it to employ at his pleasure, or almost, some of the different forms of energy , like heat, electricity, chemical affinity.

Quite recently (less than 50 years ago), understanding the imperfection of his own limbs, he endowed them with mobile mechanisms, he put cycles, devices formed of 2 or 3 wheels between the legs. and of a few light and simple organs, with which he has prodigiously increased the extent of his movements without the help of external energy.

He thus achieved 370 kilometers in 12 hours (cyclist Cadolle), and even 45,764 kilometers (record of cyclist Bouhours), while excellent athletes, on their limbs, did not achieve, at most, at the same time of 12 hours than the already very high distances of 113 kilometers (walker 5o Hibbird) or ikh kilometers (rowell runner)....

What man did for himself he can do it for animals, or at least for some of them; There is a way to increase the efficiency of their limbs by the intercalation, between these limbs and the field of motion, of mechanical devices receiving the reciprocating motion of the limbs, transforming it into continuous rotary motion, and ending in rotating parts; and the result obtained can be used to make animals move man faster and farther than has hitherto been done by using them.

A vehicle equipped with square wheels of the type contemplated by my invention gives better traction and a smoother ride when used on rough terrain than one having circular wheels. Following are the reasons: the sides of a square wheel constitute large flat surfaces for bridging ruts and cavities in the ground whereas a circular wheel follows the surface of the ground and enters many ruts; and the sides of a square wheel provide a large contacting area with the ground when they lie parallel thereto, and, hence, afford better pushing effect, whereas a round wheel affords only a small pushing area, which often results in causing a digging effect.
