A new analysis of funnel web spiders shows that factors such as heart rate and defense can impact the rate at which chemicals are distributed across the tips of their venom-producing fangs. Science Alert reports that funnel web spider venoms are complex mixtures , with many potential applications as natural insecticides and pharmaceuticals. In addition, funnel web spiders’ antivenom is used to treat deadly bites caused by them. Therefore, understanding how funnel web spiders make these mixtures will aid in more efficient extraction and use of venom, and help scientists figure out their venom function.

More than half of the world’s major lakes and reservoirs have shrunk since the early 1990s, mainly due to climate change. This situation raises concerns about the lack of water for agricultural, hydroelectric and human use. This is information given in a study published on May 18. An international team of researchers assesses that some of the world’s most important freshwater sources – from the Caspian Sea between Europe and Asia to South America’s Lake Titicaca – have been dehydrated at a cumulative rate of about 22 gigatons. every year for nearly three decades. This amount of water is equivalent to 17 times…
Satellite images taken over the past few weeks show a strong resurgence of Lake Tulare in California, USA . The reappearance of the ghost lake Satellite images taken over the past few weeks show a dramatic resurgence of Lake Tulare in California’s Central Valley and forecast that flooding could persist for the next 2 years on this arid farmland. . Although Lake Tulare is usually dry, it reappears from time to time due to floods and unusually high rainfall , hence the name “ghost lake” . Satellite images provided by Planet Labs show the transition from an arid basin to a wide, deep lake that runs about…
A new study suggests that within a month of the Big Bang, a second explosion may have given the universe invisible dark matter. Cosmologists have suggested in a new study that the Big Bang may have been accompanied by a shadow, the Big Bang that filled our universe with mysterious dark matter . And we can see evidence for that by studying the ripples in the fabric of space-time. This Hubble Telescope image of the galaxy cluster Cl0024+1654, shows small red dots of stars above a blue dark matter field. After the Big Bang , most cosmologists assumed that the universe went through a period of rapid…
