Biology and Medicine

Japanese researchers from Nagoya University have revealed new aspects of the interaction between mast plants or mass seeding plants, i.e. plants that spread their seeds at once like Sasa bamboo and field mice. Their research reveals that mouse behavior (which varies between species, and varies according to environmental conditions and seasons) plays a crucial role in seed dispersal and ecosystem health in forests, and challenges existing theories about seed storage and consumption.

Their findings highlight the importance of understanding the needs of both plants and animals to ensure the health of local ecosystems. They also overturn a previously held belief about how mice store seeds

Satellites and drones can save the pollinating insects

  • One response
Satellites and drones can provide vital information that can contribute to the protection of nature's pollinators. New research is exploring new ways to utilize these technologies to track the availability of flowers, where this research may be combined with behavioral studies to see the world through the eyes of insects

It is definitely possible to train a dog with toys if you start very early," said the lead researcher from the University of Florida. "This is what we do with search and rescue dogs, we start very early with toys as reinforcers."

Corals from the Red Sea have invaded Israel's Mediterranean coast

  • No comments
Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before

Technion researchers have identified the mechanism leading to the formation of protein aggregates involved in the development of Alzheimer's disease

  • One response
Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the reason for the accumulation of the defective proteins was unknown
