In mid-March, a one minute video of Ukraine’s president Volodymyr Zelenskiy appeared first on social media and later on a Ukrainian news website. In it, Zelenskiy told Ukrainian soldiers to lay down their arms and surrender to Russian troops.

But the video turned out to be a deepfake, a piece of synthetic media created by machine learning. Some scientists are now concerned that similar technology could be used to commit research fraud by creating fake images of spectra or biological specimen.

‘I’ve been worried very much about these types of technologies,’ says microbiologist and science integrity expert Elisabeth Bik. ‘I think this is already happening – creating deepfake images and publishing [them].’

She suspects that the images in the over 600 completely fabricated studies that she helped uncover, which likely came from the same paper mill, may have been AI-generated.

A historic drought calls for new ideas.

California and the rest of the American West are facing the worst drought in over 1,200 years.

This drought is devastating the agricultural industry and creating conditions that lead to massive wildfires. According to the IPCC, climate change makes it likely that droughts will only continue to get worse.

To maintain an adequate supply of fresh water, the region needs to develop technological solutions to dwindling water levels.

Fortunately, a decent chunk of California is on the coast, meaning one solution to the drought is utilizing desalination technologies to turn seawater into fresh water. However, large desalination plants take years to become operational and are expensive to operate (nearly $3,000 per acre-foot of seawater).

Additionally, many places experiencing drought in the West, such as Arizona and New Mexico, are not on the coast. But desalination isn’t just an option for freshening up seawater, says Brent Haddad, a professor of environmental studies at the University of California, Santa Cruz.

“[Desalination] can improve not just brackish groundwater but also agricultural groundwater that’s been harmed by chemicals and even some industrial wastes,” Haddad says.
