Gift givers hope that their gift will appropriately communicate their feelings and bring the recipient joy. But that's not always the reality. Gifts can be tricky and rife with hidden hazards. Relationships can even be ruined when the mismatch between the giver's intention and the recipient's perceptions of it is too vast. As sociologists, we use techniques such as in-depth interviews to study the experiences, feelings and motivations of specific groups of people. I focus on restaurant workers and my colleague on migrants and minorities. But in 2021, we were both diagnosed with cancer in our early 30s ' breast cancer for me and endometrial cancer for her. This encouraged us to explore the experiences of other young women dealing with cancer. By 2023, we had interviewed 50 millennial women diagnosed with cancer about a plethora of social and emotional topics related to their illness. Our own bouts with cancer revealed curious patterns in the gifts we very gratefully received from family and friends. So, we included a few questions about gifts in our research....

In case there was any doubt before, it's now undeniable that Robert F. Kennedy Jr.'s allies are in charge of the country's vaccine policy. The latest evidence: His handpicked vaccine advisory committee voted today to scrap the decades-old guidance that all babies receive the hepatitis-B vaccine shortly after birth. Now the panel recommends that only children born to mothers who test positive for the infection or have unknown status automatically receive a shot at birth. Everyone else has the option of a shot at birth or'as the committee recommends'waiting until at least two months after birth. Those who favor the change argue that other countries, such as Denmark and Finland, vaccinate only newborns of mothers who test positive, and that rates of infection are relatively low in the United States. All of this is true. But in the U.S., many expectant mothers don't get tested for hepatitis B, and even if they do, those tests sometimes fail to pick up the virus. The rationale for giving the vaccine right away is to wipe out an infection that will afflict the majority of people who contract it as babies for the rest of their life (and, for as many as a quarter of those chronically infected, result in their death from cirrhosis or liver cancer). The World Health Organization and the American Academy of Pediatrics both endorse the universal birth dose. 'When you remove that foundation, you essentially cause the whole prevention process to collapse,' Noele Nelson, a former CDC researcher who has published multiple papers on hepatitis B, told me....

Paula Hammond '84, PhD '93, an Institute Professor and MIT's executive vice provost, has been named dean of MIT's School of Engineering, effective Jan. 16. She will succeed Anantha Chandrakasan, the Vannevar Bush Professor of Electrical Engineering and Computer Science, who was appointed MIT's provost in July. Hammond, who was head of the Department of Chemical Engineering from 2015 to 2023, has also served as MIT's vice provost for faculty. She will be the first woman to hold the role of dean of MIT's School of Engineering. 'From the rigor and creativity of her scientific work to her outstanding record of service to the Institute, Paula Hammond represents the very best of MIT,' says MIT President Sally Kornbluth. 'Wise, thoughtful, down-to-earth, deeply curious, and steeped in MIT's culture and values, Paula will be a highly effective leader for the School of Engineering. I'm delighted she accepted this new challenge.' Hammond, who is also a member of MIT's Koch Institute for Integrative Cancer Research, has earned many accolades for her work developing polymers and nanomaterials that can be used for applications including drug delivery, regenerative medicine, noninvasive imaging, and battery technology....

Those are some of the offerings startups funded in the past few quarters are working to scale. A sizable cohort is also raising capital for treatment of serious pet ailments, including regenerative therapies, cancer immunotherapies and drugs for feline neurodegeneration. Overall, an analysis of Crunchbase data for pet-related startup funding shows that the space remains a lively area. So far in 2025, venture and strategic investors have poured more than $660 million into pet- and veterinary-related startup categories globally, which is roughly flat with last year. Even so, investment remains well below peaks hit a few years ago. Per Felix (and your author's observation), pet owners are increasingly treating their pets as kids. Today, there are almost twice as many U.S. households with pets than those with children, the firm reports. And among them, more than half say they would give up buying something for themselves in order to buy something for their pets. All this adds up to considerable and rising pet-related expenditures. In the U.S. alone, consumers are projected to spend $157 billion on their pets in 2025, per the American Pet Products Association, up from $152 billion last year....
