Speech recognition using artificial neural networks and artificial bee colony optimization

  Block diagram of proposed model. Credit: Shukla & Jain. Ingrid Fadelli , Tech Xplore Over the past decade or so, advances in machine learning have paved the way for the development of increasingly advanced speech recognition tools. By analyzing audio files of human speech, these tools can learn to identify words and phrases in […]

When stuck in water, bees create a wave and hydrofoil atop it, study finds

  Close study of bees in water revealed that they generate asymmetric waves, which they use to propel themselves forward.

When Beekeeping clashes with Soy Farming in Mexico

An article with superb pictures by Nadia Shira Cohen which can be found via: https://wepresent.wetransfer.com/story/nadia-shira-cohen-world-press-photo-2019/ For centuries, the Mayan beekeepers of the Yucatan Peninsula have been one of the largest producers of honey in the world. But in 2011, the Mexican government started encouraging farmers to grow soy beans, offering generous subsidies to those who did. […]

The value of Lactic Acid Bacteria in Bees’s stomachs and honey for human medicine

Picture: Lactic Acid Bacteria For centuries honey has been used as a folk medicine for the treatment of upper respiratory tract and wound infections, and even in modern hospitals, where honey is used on wound dressings. Many of its antimicrobial characteristics have been recognised but there are still unknown substances that contribute to this activity. […]

Stronger pesticide regulations likely needed to protect all bee species, say studies

Picture: Wild Bee (Credit: Nigel Raine) esticide regulations designed to protect honeybees fail to account for potential health threats posed by agrochemicals to the full diversity of bee species that are even more important pollinators of food crops and other plants, say three new international papers co-authored by University of Guelph biologists. As the global […]

A new class of insecticide—’can have a negative impact on the reproductive output of bumblebee colonies’

A new class of pesticides positioned to replace neonicotinoids may be just as harmful to crop-pollinating bees, researchers cautioned Wednesday. In experiments, the ability of bumblebees to reproduce, and the rate at which their colonies grow, were both compromised by the new sulfoximine-based insecticides, they reported in the journal Nature. Colonies exposed to low doses of […]
