Semaglutide was linked to greater weight loss and a 15% lower fracture risk in people with type 2 diabetes, raising the possibility of an unexpected bone health benefit. People with type 2 diabetes who took semaglutide experienced greater weight loss and a lower risk of bone fractures than those using several other weight-loss medications, according [...]
People taking popular GLP-1 weight-loss drugs like Ozempic, Wegovy, Mounjaro, and Zepbound may be shedding pounds, but a new study suggests they are also moving less. People with obesity who lost weight while taking popular medications such as Ozempic, Wegovy, Zepbound, and similar drugs became significantly less physically active, according to research presented at ENDO [...]
A surprising study found that cutting out sugar completely may disrupt the gut microbiome and worsen metabolic health. Cutting sugar out of your diet entirely may not be as beneficial as many people assume. New research in mice suggests that completely eliminating sucrose could have unintended effects on gut health and metabolism. The findings were [...]Researchers have identified a potential biological signature of sleep loss in saliva, bringing scientists closer to an objective test for detecting dangerous fatigue. A driver who has been awake for an entire day can be as impaired as someone who is legally intoxicated. Yet unlike alcohol, there is no roadside test that can objectively determine [...]When Victoria Glynn was a teen living in Honduras, she enjoyed making art. But that wasn’t her only interest. “Growing up in Central America, I was just surrounded by all of this amazing biodiversity,” she says. So, when it came to college, Glynn opted to study environmental science.
For undergrad studies, Glynn moved to the United States to attend the University of California, Berkeley. While there, she worked in a lab that genetically engineered yeast to produce biofuel. But she had a problem: Glynn was struggling to find diagrams to accompany talks about her research. Her mom suggested that she use her skills in art and make her own. “At the time, I wasn’t seeing other people doing that,” Glynn says. “It felt like science was in one corner, and all the arts and humanities were in the other.”
Glynn soon found other ways to bridge science and art. As an undergrad, she taught refugees and children who had recently arrived in the United States. She sometimes worked in classrooms where the students spoke many different languages. Art became a “common language for all of us to be on the same page,” she says.
Now as a visiting researcher at the University of Connecticut, Avery Point, Glynn studies how plankton are adapting to high temperatures. In this interview, she shares her experiences and advice with Science News Explores. (This interview has been edited for content and readability.)
I think what really inspired me was an undergrad class at Berkeley. One of my best friends recommended that I take this particular genetics course. I was unsure since the course wasn’t a requirement for my degree. The class seemed very removed from my interests at the time, but I still decided to enroll. I felt college was a time to explore and learn from various fields.
I remember something just clicking in my brain during one of the first lectures. Genetics and DNA felt so powerful. All organisms have DNA, which means you can track it and directly measure how it’s changing over time. Essentially, how it is evolving and mutating. After this class, I really wanted to dive into this topic more deeply.
I didn’t do a lot of marine biology work until I was in my PhD. The lab I joined for my PhD at McGill University in Montreal, Canada, was looking for someone who did genetics work, preferably in marine invertebrates. I happened to fit the bill and was interested in the project. We would take corals from their home environment and bring them onto a boat to conduct temperature stress experiments. We were interested in seeing how they build up resistance to bleaching.
Corals are beautiful animals, but they’re very hard to rear in the lab. They’re very delicate animals that do not like being in tanks. They even struggle out on the reef. That unpredictability makes experiments very difficult.
For my post-doc, I switched to studying plankton to better understand how marine organisms are being affected by warming oceans. I needed an animal that could evolve quickly over multiple generations. Plankton are much easier to grow. In as little as 11 days, you can have adult plankton that lay eggs. Compare that to corals. Some species are so long-lived that they will not reproduce within our lifetime.
I loved being an environmental science major, but I often missed that human connection when spending time in the lab. I also felt that sometimes the best researchers were not always the best at communicating their work with the general public. I wanted to share what I was learning with those who are the most affected.
Improved science communication leads to better science. In turn, embracing different backgrounds improves science education. It allows more people who are taking these courses to feel empowered and actually pursue STEM degrees. [STEM stands for science, technology, engineering and math.]
Both of my parents are divers. When I was younger, they would always talk about it. Honduras is also one of the most affordable places to get dive certified. So when I turned 12, I decided to go for it.
As I was applying for my PhD, my mother suggested that I add diving onto my CV. [A CV, or curriculum vitae, is the academic version of a resume.] I doubted whether people were going to care but added it anyway. That was the one line out of my entire CV that my future PhD advisor picked out during our interview. He was looking for someone who could handle both diving in the field and doing molecular work in the lab.
That taught me that the experiences you may not see as valuable in professional settings may be what sets you apart. You don’t know where these experiences are going to lead.
Oftentimes, you find the most unlikely mentors outside of your direct field of study. I think those can be the most important. Sometimes, those people gave me more powerful personal advice than my formal supervisors did. STEM degrees are difficult. But with a good support system, anything is possible.
As temperatures rise, it is the poor who suffer most. The coping strategies of those living in informal settlements may hold lessons for cities of the future.
Experts say increased use of crops for fuel is ‘dangerous game’ that could send food price inflation soaring
Demand for biofuels is likely to leap by nearly a third this year, which could send food price inflation soaring further and push the world closer to a global food crisis.
More countries are opting to increase biofuel use as the price of oil has jumped to nearly $100 a barrel after the US-Israeli attacks on Iran and the closure of the strait of Hormuz.

Some will question its credibility – but the alternative future to the one imagined in the Global Justice Report is far more bleak
‘An equal and habitable world is possible’: academics set out sweeping vision for planetary survival
In our increasingly dystopian world, who wouldn’t want to at least be open to a utopian antidote? The Global Justice Report, published on Thursday, outlines how to build a prosperous, equitable world within safe planetary boundaries. It’s a push from the modern eco-socialist left in a global battle for ideas that will shape the future.
Based on past social achievements and future energy transformation, it indicates that the overwhelming majority of people on the planet could, by the end of the century, work less and earn more – while keeping temperatures down and avoiding much of the current destruction of nature. It is an ambitious, comprehensive and upbeat plan, and a stronger argument around which to build a political campaign than abstract goals of net zero or decarbonisation.
