Plants may emit high frequency 'screams' when in distress
Researchers at the Tel Aviv University in Israel conducted experiments on tobacco and tomato plants, creating two different kinds of distressing situations: one in which they were deprived of water, another when their stem was cut. They placed highly sensitive audio recorders near the plants and found that the plants not only emitted ultrasonic sounds when distressed, but also emitted different sounds for different kinds of situations.

Pool, Chlorine and COVID-19
"There's nothing about a pool that would eliminate the need for social distancing, avoiding contaminated surfaces, or not breathing air from somebody who's close by," Purdue University's Ernest Blatchley said . Currently, there's no data exploring how common water disinfectants affect the Covid-19 virus specifically. It's possible that the virus may be more sensitive to chlorine and other common water disinfectants than other viruses because it has an envelope structure.

Scientists have found a way to turn solar energy into hydrogen for fuel cells
For the first time ever, scientists have been able to develop a single molecule that can turn photons in solar rays into hydrogen. This hydrogen could then be used to power fuel cells, giving us a new more efficient way to produce clean energy. Scientists still have to figure out a way to make this process and cheaper and more widely available.

Scientists say the moon might help explain origins of life on Earth
Since the moon has long been considered an area extremely inhospitable for life, scientists at the Southwest Research Institute in Boulder, Colorado have recommended that NASA should remove some restrictions designed to protect the moon from organic contamination, with the exception of the lunar south pole, where evidence of water ice still suggests its potential for explaining how life may have started on Earth.

Trump's border wall may lead to extinction of some fish species
Trump's border wall with Mexico is still under construction and requires the extraction of a large amount of groundwater. The water being taken for the wall is also the source of water that fuels the habitats of the endangered freshwater Río Yaqui fish. The water levels in this arid region are quickly decreasing and may not be enough to sustain these fish.
