About 20,000 years ago, the cave was home to generations of owls, regularly spitting out pellets containing the bones of their prey. Those discarded bones later became an unexpected resource for another group of animals. According to a new study published in Royal Society Open ScienceAncient bees used the empty tooth sockets of their fossilized jaws as small nests for their offspring. The discovery provides the first known evidence that honey bees use animal bones as a place to lay eggs, revealing an unusual nesting strategy never before documented. A cave rich in fossils that preserves an ancient ecosystem The…

Researchers have discovered hidden features beneath the Pacific Ocean that help explain why Japan’s devastating 2011 earthquake and tsunami were so destructive. The discovery also provides new clues that could improve predictions of future large earthquakes and tsunamis. A new study finds that a thin layer of soft, clay-rich sediment beneath the Japan Trench played a key role in the disaster. This unusually weak layer, located just below the ocean floor, allowed the fault to rupture all the way to the ocean trench during the 2011 “megaquake” earthquake. As a result, the ocean floor moved abnormally by 130 to 200…

A recent study found that athletic appearance was associated with young Afghan refugee men being more likely to form romantic relationships with women who had higher educational or legal status in Germany. This finding suggests that physical characteristics may serve as exchangeable assets for new arrivals as they navigate legal and social insecurities in their new societies. The study was published in the Journal of Wedding and Family. In 2015 and 2016, Germany experienced a large influx of asylum seekers from the Middle East and Central Asia. Due to the dangerous nature of the migration routes, many of these arrivals…

For much of the early 20th century, quantum mechanics was one of the most puzzling ideas in science. The theory challenged conventional thinking, and even leading physicists struggled to make sense of it. A century later, it is the basis for technologies that impact our daily lives, including lasers, microchips, secure communications, and emerging quantum computers. In the New Perspective article published in scienceDr. Marlan Scully of Texas A&M University reflects on the remarkable evolution of quantum mechanics, from an abstract theory of tiny particles to a powerful framework that helps researchers tackle some of science’s most difficult problems. “Quantum…

A new study published in Applied Economics Letters suggests that deep-rooted cultural beliefs about class and gender roles can prevent highly educated women from fully participating in the workforce. The findings show that in societies that value rigid social hierarchies, even advanced education for women does not help close the economic gender gap. These cultural barriers tend to overwhelm the normal career benefits of a good education. Scholars continue to document that gender inequality in the workplace remains a persistent global problem. According to a United Nations report cited in the study, no country has achieved full gender equality, and…

An engineered three-phase biomaterial scaffold successfully recreated the cranial suture stem cell niche lost in craniosynostosis, a condition that causes premature fusion of the skull bones. Using a pore size-dependent “bone-suture-bone” design, this scaffold maintained skeletal stem cells while supporting surrounding bone formation. In mouse models, this construct prevented refusion, restored craniofacial growth, and improved skull morphology. This discovery could advance regenerative therapies that directly address the underlying causes of pediatric craniofacial disorders. Craniosynostosis is a congenital disorder in which one or more fibrous joints between the skulls fuse together prematurely during development. The disease, which affects 1 in 2,500…

A new Europe-wide survey launched during the 42nd European Society of Human Reproduction and Embryology (ESHRE) Annual Meeting suggests broad public support for several areas of infertility treatment and reproductive research, and highlights key areas where public understanding and opinion continues to develop. The report states:Fertility, embryo research, and genome editing: public attitudes in Europewas commissioned by the charity Progress Education Trust (PET) and carried out by Ipsos with support from ESHRE. We investigated public attitudes towards infertility treatment, embryo research, genome editing, surrogacy and related topics in the UK, Netherlands, Spain and Italy. The survey involved 8,688 people aged…

As the oldest baby boomers turn 80, the nation’s nursing homes are bracing for the expected increase. The number of people with dementia, disabilities, and needing assistance with activities of daily living is increasing while the number of nursing home beds is decreasing. Nearly 10% of U.S. nursing homes closed between 2011 and 2021. Additionally, direct care providers are exiting the industry in droves. In an opinion published July 4 in the New England Journal of Medicine, Dr. Mark A. Unruh and Dr. Hyeyoung Jeong, associate professors of population health sciences at Weill Cornell Medical College, along with Dr. Vincent…

Artificial intelligence companions are becoming very good at imitating human conversations and providing support. However, relying on them may not actually alleviate feelings of loneliness. A new study published in the Journal of Experimental Social Psychology found that texting a random human co-worker every day was successful in reducing feelings of loneliness over time, but chatting with a highly cooperative artificial intelligence program did not. This finding suggests that building real social connections requires more than just receiving pseudo-empathy. The debate about whether humans can truly connect with machines is not entirely new. About 60 years ago, a computer scientist…

Recent research published in Sex & Couple Therapy Journal More than half of adults worry about their sex drive, suggesting that most of their worries center around feeling like their sex drive is too low or doesn’t match their partner’s level of desire. The findings provide evidence that everyday stressors, mental health challenges, and relationship dynamics play a major role in how people perceive their sexual desires. This research helps explain the different ways in which individuals experience and interpret changes in sexual motivation. Sexual desire is generally understood as a person’s internal motivation for seeking sexual experience and pleasure.…
