With the advancement of technology, the development of telecommunication industries, the construction of new electrical devices, and the increasing use of electromagnetic field generators in modern industrial societies, the study of the biological effects of these waves on the growth and development of living organisms are of interest to many societies. The scientific world is placed. Today, one of the ecological problems is electromagnetic pollution in the environment. The use of mobile phones has increased in the world in recent years, which in turn adds to this pollution. Some bee species worldwide are becoming extinct, called the CCD phenomenon. Our goal in this article is to investigate the effect of electromagnetic waves and their relationship with the new phenomenon of CCD and to offer a proposal to guide bees to return to the hive by fluorescent blue light.

Although cancer is a recognized disorder worldwide, its treatment is a great challenge; and new and effective treatment methods become one of the fundamental demands. However, one of the new treatment approaches for cancer is hyperthermia, which is considered an assistant to surgery, chemotherapy, and radiotherapy. Despite the proven effectiveness of the method, there are numerous challenges in applying it that require recognizing the effective parameters and optimizing them to achieve better and more effective performance. Considering this, the review paper aims to study the optimization of antennas utilized in the cancerous tissue treatment by hyperthermia. However, four different antennas with different purposes are studied and optimized for this purpose. Furthermore, studies show that recognizing and optimizing the design parameters of hyperthermia antennas is likely to greatly improve the performance of the method.

Today, one of the biological problems is electromagnetic pollution in the environment. The intensity of electromagnetic radiation is so pervasive that it is now known as a form of latent and silent pollution. The study of the biological effects of these waves on the growth and development of living insects - such as bees - are considered by many scientific communities around the world. However, the response of honey/wild bees to traps designed to selectively stimulate bee light receptors by fluorescent light indicated that selective arousal of the blue light receptor type was highly attractive. In this paper, to selectively stimulate the blue light receiver in bee species in order to guide the bee navigation system to return to its hive and prevent the colony collapse disorder (CCD) phenomenon, high-efficiency continuous laser emission by second-harmonic line width of 456 nm Nd:GdVO4 laser is proposed.

Rapid progress in various fields of science and technology in recent years has caused various adverse and predictable negative effects on the environment. Today, one of the most important biological problems is environmental electromagnetic pollution. The intensity of its electromagnetic radiation has become so widespread that it is currently known as one of the hidden and silent forms of pollution. One means of communication that is an inseparable part of daily life is the mobile phone. Research and surveys show that mobile phone waves have a negative effect on the human body. Our goal in this article is to study the effects of mobile phone electromagnetic waves on the human eye. In order to check the effect of these waves, the specific absorption rate (SAR) criterion is used. Because the rate of specific absorption in the eye is determined according to the absorption of energy in the eye tissues and the conversion of this absorbed energy into thermal energy, they increase the temperature of the eye tissues. In other words, the temperature distribution in the eye directly correlates with the rate of specific absorption. The results have shown that the tissue of the eye is susceptible. When the eye is exposed to waves, the eye’s temperature increases, and the antenna angle relative to the eye is effective in the rate of specific absorption. According to studies, the conclusion of this research indicates that without observing safety points, including maintaining distance, they can cause dangerous bodily complications.
