Over 300 Brazilian teens: early bullying linked to worse self-view a year later
Without the MTCH2 protein, only 5% to 10% of mouse precursor cells became fat cells
John Korir needs to cut 2:24 from his best to run a sub-two marathon in Valencia

1In mouse cells, switching off one protein stopped most fat cells forming
What happened. In mouse cells and human cells grown in a lab, researchers at the Weizmann Institute of Science switched off a protein called MTCH2, nicknamed Mitch. The human cells then burned more fuel, including fat. Within 6 days, 80% to 90% of normal mouse precursor cells became mature fat cells, against only 5% to 10% without MTCH2. Both studies were published in 2025.
“In other words, we showed that Mitch determines the fate of fat in human cells.”
Professor Atan Gross, Weizmann Institute of Science
Why it matters. The work helps explain how cells decide whether to burn or store fuel. It does not show that blocking this protein is safe or useful in people, and the protein has other jobs in the body.
2Bullying in one school year linked to a harsher teen self-view later
What happened. Jonathan Santo, a psychology professor at the University of Nebraska at Omaha, and his team followed more than 300 teenagers in Curitiba, Brazil, for two school years. Teasing and insults from peers reported in the first year were linked to a more negative self-view over a year later. Bullying that kept going over time explained this link.
“Our study couldn't disentangle causes from effects.”
Jonathan Santo, professor of psychology, University of Nebraska at Omaha
Why it matters. Most teens in the study, 64.8%, felt positive about themselves. Ongoing teasing and a harsh self-view tend to go together, so repeated teasing is worth noticing early, even though the study cannot say which comes first.
Self-reports from one Brazilian sample; cannot show cause, and the link may run both ways
3Follow-up questions can turn small talk into deeper talk, a doctor argues
What happened. Manu Sidhu, a mental health doctor writing in Psychology Today, argues that small talk can open the way to deeper conversation rather than block it. Light questions help a person spot what matters to the other. The piece points to a 2017 study series in which people who asked more follow-up questions were better liked.
Why it matters. The pressure moves off the perfect opening line. Listening for what matters to the other person, then asking one good next question, may matter more. Sometimes a light chat is enough.

4A psychologist argues good communication starts with the other person
What happened. Howard J. Rankin, a psychologist and author, writes in Psychology Today that people talk and persuade better when they first learn what matters to the listener. He says no one in his training ever taught communication, a gap he noticed after more than a decade in practice.
Why it matters. Rankin notes that one of the biggest reasons patients change doctors is feeling that the doctor does not understand them. Asking what matters to the other person may help a message land, in a clinic or a sales meeting.

5Two-time Boston winner John Korir hopes to run under 2 hours in Valencia
What happened. Kenyan runner John Korir, who has won three World Marathon Majors, has signed a sponsorship deal that runs to the 2028 Los Angeles Olympics. He has never raced an Olympics or world championships for Kenya. On 6 December he defends his Valencia title, hoping to run under 2 hours, which means cutting 2:24 from his official best of 2:02:24.
“Any time I get in Valencia I will be happy with, but my prayer is to run sub-two hours”
John Korir, two-time Boston Marathon champion
Why it matters. Only three men per country can start an Olympic marathon, so his place is not certain. His path shows how steady progress can build over many years.
