Which parasitic plant searches for a prey plant by smell?

Dodder is a parasitic plant that does not have roots and leaves and feeds only on the juices of the host, the stem of which it wraps around. When a dodder sprout emerges from the ground, it searches for the victim's stalk by smell and purposefully grows in its direction. Volatile organic substances from some plants like dodder more than from others, and the most favorite host for her is the tomato. The fact that the smell is the main chemical irritant for the parasite is proved by the fact that the sprout also reaches for an artificial source of volatile substances that are attractive to it.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Mussel paste 03.12.2015

The incredible ability of mussels to stick to underwater surfaces has long attracted the attention of scientists. A few years ago, researchers at the University of North Carolina (USA) tried to isolate and dissolve the proteins that "glue" mollusks, and then use the protein solution to seal wounds using piezoelectric technology, which is used in inkjet printers. And last year, scientists at the Massachusetts Institute of Technology made a waterproof adhesive based on the same proteins with the addition of fibrillar proteins isolated from the bacterium E. coli.

This year turned out to be especially successful for the clam paste. In the summer, researchers from the Pohang University of Science and Technology (South Korea) found that when shellfish proteins containing the amino acid tyrosine are irradiated with blue light, a photochemical reaction occurs, as a result of which a stable structure is formed, similar to the wings of a dragonfly, but also sticky. More recently, scientists from the University of California at Santa Barbara (USA) have received an ultra-thin synthetic material that is ten times more effective than previous waterproof developments.

The amino acid levodopa was used as a sample, which provides underwater bonding and also promotes wound healing. This is due to the catechol, which forms hydrogen bonds, which prevents the byssus, the protein filaments secreted from the legs of mussels, from contacting water. The researchers managed to create a molecule that, like proteins, forms ultra-thin adhesive layers that are able to hold two surfaces together under water. In addition to adhesive properties, the material can be useful in the production of electronic components: its ultra-thin layers can serve as a substrate for microcircuits.
