| Building mechanical memory boards using origami Posted: 25 Aug 2020 08:55 AM PDT Origami can be used to create mechanical, binary switches, and researchers report the fabrication of such a paper device, using the Kresling pattern, that can act as a mechanical switch. By putting several together on a single platform, the investigators built a functioning mechanical memory board. They found that oscillating the platform up and down at a certain speed will cause it to flip, or switch, between its two stable states. |
| Vast stone monuments constructed in Arabia 7,000 years ago Posted: 25 Aug 2020 08:36 AM PDT New archaeological research in Saudi Arabia documents hundreds of stone structures interpreted as monumental sites where early pastoralists carried out rituals. |
| Plant living with only one leaf reveals fundamental genetics of plant growth Posted: 25 Aug 2020 08:07 AM PDT Clinging to the walls of tropical caves is a type of plant with a single leaf that continues to grow larger for as long as the plant survives. Researchers hope that their study of this unusual species may help inspire future genetic tools to control the size of common crop plants. |
| New study shows evolutionary breakdown of 'social' chromosome in ants Posted: 25 Aug 2020 08:07 AM PDT Scientists have found that harmful mutations accumulating in the fire ant social chromosome are causing its breakdown. |
| Life in a nutshell: New species found in the carapace of late cretaceous marine turtle Posted: 25 Aug 2020 08:07 AM PDT Scientists have identified a new ichnospecies from the shell of an extinct marine turtle fossil, the first known species coexisting on living marine vertebrates. |
| Posted: 25 Aug 2020 08:07 AM PDT Scientists measure the propulsive force of water polo players executing highly efficient 'eggbeater' kicks, paving the way to improved sports performance and new undersea transportation methods. |
| Galactic bar paradox resolved in cosmic dance Posted: 25 Aug 2020 08:07 AM PDT New light has been shed on a mysterious and long-standing conundrum at the very heart of our galaxy. The new work offers a potential solution to the so-called 'Galactic bar paradox', whereby different observations produce contradictory estimates of the motion of the central regions of the Milky Way. |
| Two major microbial groups living deep underground can't breathe Posted: 25 Aug 2020 08:06 AM PDT A new scientific study has revealed unique life strategies of two major groups of microbes that live below Earth's surface. These groups, originally thought to rely on symbiotic relationships with other organisms, may also live independently and use an ancient mode of energy production. |
| Tracing the cosmic origin of complex organic molecules with their radiofrequency footprint Posted: 25 Aug 2020 08:06 AM PDT How did organic matter reach the Earth in the first place? One way to ponder this question is by observing the distribution and abundance of complex organic molecules in interstellar gas clouds. However, detecting such molecules in the less dense regions of these gas clouds has been challenging. Now, scientists have found concluding evidence for the presence of a particular complex organic molecule in such a region for the first time. |
| Ancient star explosions revealed in deep-sea sediments Posted: 25 Aug 2020 08:06 AM PDT A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments. |
| A novel approach produces a completely new kind of dynamic light structure Posted: 24 Aug 2020 06:20 AM PDT Researchers showed how combining twisted light and frequency combs together can produce an even more novel structure of light. |
