| Underground carnivore: the first species of pitcher plant to dine on subterranean prey Posted: 29 Jun 2022 09:12 AM PDT A remarkable new species of carnivorous plant was discovered in a remote part of Borneo. It is the first pitcher plant known to produce functional underground traps, and the first for which capture of subterranean prey has been observed. While the traps themselves are often a rich maroon colour, they are produced on shoots that are entirely white, owing to their lack of chlorophyll. |
| Falling stardust, wobbly jets explain blinking gamma ray bursts Posted: 29 Jun 2022 09:11 AM PDT Astrophysicists have developed the first 3D simulation of the entire evolution of a jet -- from its birth by a rotating black hole to its emission far from the collapsing star. Simulation shows that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the jet, which wobbles as it struggles to return to its original trajectory. The wobbling jet explains the longstanding mystery of why gamma ray bursts blink and shows that these bursts are even rarer than previously thought. |
| The emergence of form: New study expands horizons for DNA nanotechnology Posted: 29 Jun 2022 09:10 AM PDT Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form elaborate, self-assembling crystal lattices at the nanometer scale, (or roughly 1/75,000th the width of a human hair). |
| Robot overcomes uncertainty to retrieve buried objects Posted: 28 Jun 2022 02:01 PM PDT FuseBot is a new robotic system that fuses visual information and radio-frequency signals to efficiently find hidden items buried under a pile of objects, whether or not the targeted item has an RFID tag. |
| Is there a right-handed version of our left-handed universe? Posted: 28 Jun 2022 02:01 PM PDT To solve a long-standing puzzle about how long a neutron can 'live' outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment to try to detect a particle that has been speculated but not spotted. If found, the theorized 'mirror neutron' -- a dark-matter twin to the neutron -- could explain a discrepancy between answers from two types of neutron lifetime experiments and provide the first observation of dark matter. |
