Authorities have identified the faculty member killed in Monday’s shooting at the University of North Carolina at Chapel Hill. UNC PhD student Tailei Qi, 34, has been charged with first-degree murder in connection with the killing of Zijie Yan, an associate professor in the Department of Applied Physical Sciences and a researcher. Mr Yan was listed as his alleged killer’s academic advisor on Mr Qi’s UNC profile, which has since been removed from the university’s website. Yan joined UNC in 2019. Before that, he was an assistant professor at Clarkson University in New York and received postdoctoral training at the University of Chicago. Mr Qi and Yan co-authored several research papers focusing on nanoscience technology. But in tweets from an account believed to belong to Mr Qi, the alleged shooter complained about “bullies and his “PI” – referring to his unnamed head of lab – being unable to handle “these girls and tattletales”. “Just have a talk with my PI and get his promise. He should have more experience to handle with these girls and tattletales,” he wrote in August 2022. Two months later in October, he referred to his PI again: “Both the group of people to say I am lazy and that to prove me working hard instead of telling me that are trying to consume my privacy. I judge their motivation is only to tell my PI then control me by taletelling.” “But it’s weird when I talked about it with my PI, he said no people spoke to him about that. so it’s nothing but some voyeurism for these people?” Yan studied undergrad at the Hauzhong University of Science and Technology, where he obtained his bachelor’s in material science and engineering and computer science in 2005. The Rensselaer Polytechnic Institute, where Yan got his master’s in physics electronics, posted a tribute on Tuesday. “He is remembered fondly by many of us that met him in the classroom, lab, or in the hallway of MRC,” a Facebook post read. “Among other things, he distinguished himself with publishing 17 journal articles in the course of his PhD study...” UNC at Chapel Hill Chancellor Kevin M Guskiewicz said in a statement on Tuesday that he has met with Yan’s family. “My leadership team and I have met with his colleagues and family to express our condolences on behalf of our campus,” the statement read. “Please join me in thinking and praying for his family and loved ones during this difficult time.” UNC police said during a press conference on Monday that a motive was not immediately evident. Mr Qi, a second-year PhD student majoring in applied physical sciences, graduated from Wuhan University in 2015 and also received a master’s in material science from Lousiana State University in 2021. The suspect joined UNC at Chapel Hill’s Yan Lab in 2022. UNC graduate student Aiden Scott, a former classmate of Mr Qi, described him as “very quiet” but “nice.” “I would have never guessed that he would be the kind of person who could possibly be capable of this kind of thing,” Mr Scott told WRAL. “Every single time he would talk to me, he seemed very nice... when I saw his face in the reports online, I was beyond shocked,” UNC has cancelled all classes on Tuesday as an investigation remains ongoing. Mr Qi is expected to appear in court later today.

What do you reckon the chattiest vegetable is? The answer may be mushrooms, as according to a new study from scientists in Japan, rain may prompt some fungi to communicate using underground electrical signals. In a study published in Fungal Ecology , researchers monitored small, tan mushrooms known as bicoloured deceivers in the mixed forest at the Kawatabi Field Science Center of Tohoku University in Japandorm. They looked at the 'shrooms electrical potential, measured in megavolts (mV), for about two days in late September and early October 2021. The study site was initially sunny and dry, and the second was during rain - at which point the mushrooms showed some electrical potential and signal transport between each other. Microbial ecologist Yu Fukasawa of Tohoku University said: "Our results confirm the need for further studies on fungal electrical potentials under a true ecological context."

These sheaths are made of hyphae and when they link underground they form interconnected systems known as mycorrhizal networks that allow forests communicate via chemical signals down tree roots and mycorrhizal fungi. And a 2022 study found patterns of nerve-like electrical activity in some fungi that seem comparable to the structure of human speech. The study identified up to 50 different "words," or groups of spikes in electrical activity, generated by fungal networks. Earlier research has also found that plants can send secret electrical signals underground, possibly even without help from mycorrhizal fungi. Who knew mushrooms had so much to say?
