4 . A team of researchers from the Universities of Washington and Toronto have developed an app, FeverPhone, suitable for diagnosing (诊断) a patient’s fever.
“As an undergraduate, I was doing research in a lab where we showed that you could use the temperature sensor in a smartphone to measure air temperature,” says lead author Joseph Breda. “When I came to the UW, my adviser and I wondered how we could apply a similar technique for health. We decided to measure fever in an accessible way. The primary concern with temperature isn’t that it’s a difficult signal to measure; it’s just that people don’t have thermometers (体温计).”
“In a wave of flu, for instance, people running to the emergency room can take a week sometimes. So if people were to share fever results with public health agencies through the app, this earlier sign could help us take action sooner,” adds Mastafa Springston, co-author of the study.
The trick is to use the temperature sensor already present in a smartphone. A patient holds the smartphone’s display against their forehead for 90 seconds, and the rise in temperature is compared against the surrounding temperature to determine their core body temperature — using a machine learning model trained on a number of test cases to calibrate the results.
It may sound like a crazy approach, but in testing, the FeverPhone app was able to estimate the core body temperature of 37 patients in a real emergency department with an average error of 0.23℃ — around half the 0.5℃ error range required for clinical use.
“We started with smartphones since they’re easy to get data from,” Breda says. “I am already working on seeing if we can get a similar signal with wearables like smartwatches. What’s nice, because watches are much smaller, is their temperature will change more quickly. So you could imagine having a user put a Fitbit to their forehead and measure in 10 seconds whether they have a fever or not.”

5 . If there’s one thing I’ve realized since becoming a male college student, it’s that finding a summer job is nearly impossible. I’ve applied to so many places and I’ve experienced so many interviews, but I always either get straight-up refusal or never hear from the company again.
One time, I even called one of the companies multiple times, but the manager avoided me. I was close to giving up. I felt like I was the only one struggling hard. I had a pretty good resume, and I always dressed nicely for my interviews, so why couldn’t I get a job?
Well, the reason is actually right in front of me—I am a student. Companies generally want students who can work all year long, but most of them aren’t willing to be flexible with schedules. I couldn’t tell you how many times interviewers told me that they were looking for someone permanent.
I tried looking for jobs marked as temporary ones. And I even once tried to apply through a temporary agency. But it didn’t work. Even if I wanted to work during the school year, none of the companies wanted to hire me because of my limited weekday availability. And despite not knowing if I could juggle (尽量兼顾) both school and a job, I even started to tell interviewers that I would like to work during the school year and give up my weekends. But I had no luck.
I’m not sure if there are others like me out there. But if you are going through something similar, what I want to tell you is to keep on trying. Despite being rejected so many times, I still applied for any job that I was qualified for. I even started my job search before the semester ended to get ahead. Eventually, I got my ideal summer job.
I know it’s frustrating, and you may feel like you’ve tried everything—that’s how I’ve felt for a long time. And now, with companies requiring years of experience, it’s even harder to get a job if you’re someone like me. But don’t give up. Keep searching and applying, sign up for sites that send you job offers and look on the university’s website for on-campus jobs.

When Mary entered the south Pole Penguin Research Lab, she saw her friend Tom gently stroking (轻抚) a penguin in his arms. As children of the lab scientists, Mary and Tom often observed the emperor penguins that were studied to understand how they adapted to extreme temperatures —insights that could aid human survival.
“We’re thirteen, Tom. It’s time to grow up and stop playing with the lab penguins,” said Mary as she started cleaning. “They’re research animals, not pets.”
“But the birds listen to me1” insisted Tom, his breath forming a cloud in the freezing air. “You’re just trying to be a penguin whisperer again,” Mary replied, shaking her head with a gentle smile. The penguins seemed playful as they walked, dove, swam and chased their live fish for sport before eating.
Suddenly , an alarm rang out and red lights flashed , signaling a problem. The kids rushed over to look into it. “It’s colder than before —there’s ice forming on the water,” noted Tom. Though always cold, Mary had never seen ice here before. She checked the habitat monitor and found that the temperature had gone down a lot. “The heater must be broken!”
Mary quickly sent a message to their parents’ research team, who were conducting outdoor studies. With the adults away, the kids would have to deal with the freezing conditions until help arrived.
Time dragged as Mary and Tom anxiously waited. The increasing cold caused them to shake. “I wonder what emperor penguins do in extreme cold, since they stay in the Pole all winter instead of going somewhere warmer,” asked Mary. “They huddle (挤作一团), ” Tom answered. “They huddle together tightly so that the birds in the middle will be warm enough.” “What about the ones on the edge?” Mary asked. “They push their way towards the center, and then move back out to the edge, and struggle back again. Scientists in the early 21st century recorded it.” He replied as he stared at the large crowd of the penguins in the lab.
