After two years of work, Martin Molin of the Swedish band Wintergatan debuted a fully custom-made machine that plays music using 2,000 marbles. The marble machine features multiple instruments including a bass guitar, cymbals, and a vibraphone all played by falling marbles. Apart from the 11 mm steel ball bearing marbles, he made all the gears powering the machine by hand.

To tap into scarce water supplies, most desert plants have extensive root systems that burrow deep or spread wide. But one desert moss has a different trick up its sleeve: a thirst-quenching structure called an awn. Awns are tiny, hairlike structures that project from the end of each leaf to capture water (above). For the first time, scientists have examined in detail how this moss (Syntrichia caninervis) pulls water right from the air using its awns. At the smallest scale, the awns are covered with grooves about 100 nanometers deep and 200 nanometers wide, the perfect size for dew to condense within them when conditions are right. Those nanogrooves lie within larger troughs that measure about 1.5 micrometers deep and 3 micrometers wide, a ...

Lysergic acid diethylamide (LSD) is a recreational, psychedelic drug that alter awareness of the surroundings, perceptions, and feelings, as well as sensations and images that seem real though they are not.

LSD works by binding primarily to the dopamine receptors and adrenal receptors in the brain. It also binds to most of the serotonin receptors. The binding process is believed to overstimulate the natural neurotransmission process, activating the receptors and altering thought and perceptions.

Though medical researchers have not scientifically proven how this process alters consciousness, they are certain about the binding process which links hallucinogenic chemicals to receptors and disrupts neurotransmission between receptors and parts of ...

Christmas Island is a unique natural habitat located in the Indian Ocean with many endemic species. The national park covers two-thirds of the island, which has been referred to as the Galapagos of the Indian Ocean.

Many people are aware of the red crabs whose mass migration to the sea has been described as one of the wonders of the natural world. Christmas Island has many other species of crabs, including the impressive robber crabs (Gecarcoidea natalis). These may be the largest land-dwelling arthropod on Earth.

Together these abundant land crabs clear the forests of leaf litter and maintain burrows that prevent soil becoming compacted, creating an open and diverse forest.

This thriving natural system, however, was disrupted by an invasive ...

Rattlesnakes are a group of venomous snakes native to the Americas known for their loud rattling tail. The tip of their tail, known as the rattle (middle), vibrates to deter predators or serves as a warning to passers-by.

The rattle is composed of a series of hollow, interlocked segments made of keratin, which are created by modifying the scales that cover the tip of the tail. The contraction of special "shaker" muscles in the tail causes these segments to vibrate against one another, making the rattling noise (which is amplified because the segments are hollow) in a behavior known as tail vibration. The muscles that cause the rattle to shake are some of the fastest known, firing 50 times per second on average, sustained for up to three hour ...

So, does stress really cause your beautiful golden locks to turn silver?

India’s tiger population has risen from 1,706 individuals to 2,226 in the past four years, officials have reported. With the global population teetering around 3,000 individuals, this kind of growth is incredible.
