What molluscs are able to hide from predators by moving on land?

Some species of octopuses are able to leave the water for a while and move on land, pushing off with their tentacles. The purpose of their exit from their native element can be both to search for prey in small puddles that remain after the sea ebb, and to escape from larger predators.

Why was Socrates sentenced to death?

Socrates (470-399 BC), one of the greatest ancient Greek philosophers, who became for subsequent generations the embodiment of the ideal of the sage, was sentenced to death by the Athenian authorities and took hemlock poison.

It all started with the fact that Melitus, who was known as a poet in Athens, accused Socrates of allegedly breaking the law, trying to explore what is under the earth and what is in heaven, "passing off lies for truth and teaching the same to others." Socrates was accused of violating piety, and of denying the gods recognized by the Athenians and introducing new ones, and even of accepting demonic signs. This was said publicly.

The hidden motive of the accusations was different: Socrates' clever, sharp and ironic statements undermined the Athenian slave-owning democracy. This proves the course of voting in court. When the judges first decided on the guilt of Socrates, only a small number of votes were cast against him. However, the second speech of Socrates - on the measure of punishment, full of mockery of the traditions of the Athenians and not expressing remorse - led the judges into indignation. Socrates was sentenced to death by an overwhelming majority.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Flexible Solar Panel for Boats 19.02.2023

Lightleaf has developed a new 110W carbon fiber PV module for boats.

"Our latest product is designed for the offshore market focused on sailing and powerboats with limited space, where weight, functionality and appearance are important," a company spokesperson said. "We have designed the seaLeaf panel with built-in hardware, but there are also panels with interchangeable mounting kits designed to work in the marine environment."

The Canadian solar manufacturer said the SeaLeaf has a rigid carbon fiber foam base instead of glass. Its dimensions are 1073 x 575 mm, thickness 9 mm and weight 2,5 kg. The curved solar panel includes two quick-release clamps mounted 50cm apart. They're supposed to be able to attach to any one-inch rail and go back 180 degrees to track the movement of the sun.

The new module has an open circuit voltage of 22,9 V and a short circuit current of 6,35 A. It uses 32 SunPower Maxeon GIII Premium ME3 monocrystalline solar cells with an efficiency of 25,1%. The junction box is sealed, uses two shunt Schottky diodes and is IP67 rated. The unit includes a 3 AWG 14 AWG marine grade round cable with a XNUMX meter spigot end for easy installation of the bulkhead gland.

The SeaLeaf costs $650 and comes with a three-year manufacturing warranty and a five-year power output warranty. Leightleaf has previously developed carbon fiber solar panels for the RV market, but has mainly targeted small trailers with limited space.

The feature of the panels allows them to be installed during transportation and removed/deployed during parking.
