Here we are, yet again at your doorstep with the latest scientific discoveries
1. Mosquito’s vision changes: study says they see red
According to a study conducted by the University of Washington, your clothing could help you battle a mosquito this summer. How? Mosquitoes use odor to discriminate between neighboring hosts. When they detect carbon dioxide chemicals in our breath, their eyes search for specific colors and patterns linked with the host and move towards them. Mosquitoes’ responses to visual signals are influenced by their sense of smell [olfaction]. They are drawn to the color red, as well as your breath, sweat, and skin warmth. Humans and other animals are unable to detect CO2, but mosquitos can, and the scent of CO2 stimulates female mosquitos to seek out a host, similar to what happens when humans smell good food.
2.Climate change has started to affect fisheries
Before they start touching us, certain conversations are dismissed as myths or fables. Climate change has been a long-discussed topic, and its effects are now beginning to be seen. According to research, by 2080, about 70% of the world’s seas will be experiencing an oxygen shortage, which will have a significant impact on our marine life. According to new research, fisheries in the mid-ocean depths are already losing oxygen at an alarming rate. Water, like the air, contains dissolved oxygen, which is absorbed by people and animals. Despite scientists’ warnings about the devastating effects of climate change, it appears that it now has to be handled as a serious matter. Deoxygenation in 2021 is affecting the middle-depths of the oceans, which is likely to affect all ocean zones by 2080.
3.Netherlands report a new and highly damaging variant of H.I.V
The ongoing COVID-19 pandemic has heightened global awareness of how devastating virus mutations can be and how they can effectively shut down human existence. The HIV-1 virus continues to affect 38 million people worldwide and has claimed the lives of 33 million people. The University of Oxford researchers have now rung an alert to the rest of the globe, urging everyone to pay attention to and recognize this new H.I.V strain that has now been detected in the Netherlands. When compared to people infected with previous HIV variants, the novel variety known as the ‘VB’ variant exhibited differences before antiretroviral treatment. The patients’ viral loads are believed to be between 3.5 and 5.5 percent higher, and the danger of transmission is also increased when diagnosed with this new variant.
4.Lack of sleep can triple the risk of heart diseases
Sleep deprivation is becoming more common among teenagers, who have so many things to keep them occupied that they end up waking up all night. However, not getting enough sleep might be dangerous to one’s heart. The sleep data of 6,820 U.S. individuals with an average age of 53 who self-reported their sleep characteristics and heart disease history were analyzed in a study sponsored by the University of South Florida. Researchers looked at a variety of sleep-related factors, including regularity, contentment, and attentiveness during waking hours. Each extra rise in self-reported sleep health problems was linked to a 54 percent increased risk of heart disease, according to the researchers. For those who provided care, the predicted risk of heart disease, related to an increase in sleep health problems was substantially higher. The estimated risk of heart disease associated with an increase in sleep health problems was much higher for those who provided sleep data by both self-report and the research device.
