Rich medieval Christians bought graves 'closer to God' despite leprosy stigma, archaeologists find‎

Medieval Christians in Denmark showed off their wealth in death by buying prestigious graves: the closer to the church, the higher the price. Researchers used these gravesites to investigate social exclusion based on illness, by studying whether people with leprosy—a highly stigmatized disease culturally associated with sin—or tuberculosis were kept out of the higher-status areas.

Climate anxiety: Misconceptions and advice‎

Many people feel anxious about climate change and other trends in the world around us. However, there are constructive ways to cope with one's emotions. In step with the incorporation of the word "klimatångest" (climate anxiety) in the Swedish vocabulary, more and more researchers have become interested in the concept. One of them is Marlis Wullenkord, associate senior lecturer in environmental psychology at Lund University.

'Gaybourhoods' boost LGB voter turnout‎

Living near other lesbian, gay, and bisexual (LGB) people makes LGB people significantly more likely to vote, according to new research published in The Journal of Politics. When the share of LGB residents in a neighborhood increases by just one percentage point, LGB residents become 1.56 percentage points more likely to vote compared to heterosexual neighbors, according to the study.

Antarctic magnetic anomaly is a trace of an ancient continental collision, scientists find‎

Geologists from St. Petersburg State University, as part of an international scientific team, have analyzed rock data from East Antarctica and determined that the magnetic anomaly in this region resulted from the convergence of continents and the birth of the supercontinent Rodinia approximately 1 billion years ago. The research is published in the journal Polar Science.

Assessment quantifies nitrogen retention and carbon sequestration in China's forests‎

A research team from the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences has clarified how deposited nitrogen is retained in forest ecosystems and how this process contributes to carbon sequestration across China. The findings were published in Global Change Biology on January 30.

Sleek, lithe and extremely rare: This elusive California fox has finally been GPS-collared‎

The stunning Sierra Nevada red fox is one of the nation's rarest and most critically threatened mammals, with fewer than 50 believed to remain in the Sierra. And now, for the first time, a specimen has been successfully GPS-collared and released back into the region—marking a major victory for conservation efforts to protect the elusive vulpine.

Rocket science? 3D printing soft matter in zero gravity‎

What happens to soft matter when gravity disappears? To answer this, UvA physicists launched a fluid dynamics experiment on a sounding rocket. The suborbital rocket reached an altitude of 267 km before falling back to Earth, providing six minutes of weightlessness.

Valentine's day: Can 36 questions really change your love life?‎

About a decade ago, author Mandy Len Catron wrote an essay for the New York Times about "36 questions that lead to love." The idea suggests that two people can grow closer—and even fall in love—by answering a series of increasingly intimate questions.

Unseen planet or brown dwarf may have hidden 'rare' fading star‎

One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, astronomers say. For decades, the star—which sits 3,200 light-years from Earth and is about twice as big as our sun—had been observed as stable, but at the end of 2024 it faded dramatically.

New model tracks antimicrobial resistance genes across gut, wastewater, soil and air‎

A multinational research team led by Professor Tong Zhang from the Department of Civil Engineering, Faculty of Engineering at the University of Hong Kong (HKU Engineering), in collaboration with an international team, has developed a new framework to assess and track antimicrobial resistance (AMR) connectivity across human, animal, and environmental sectors. The study systematically examines the connectivity of AMR and proposes an assessment framework along with mitigation strategies.
