RAINY DAY WOMEN.
In the United States, as reproductive health care access faces threats, more women are stocking up on abortion medications for future use. A study led by Abigail Aiken of the University of Texas at Austin analyzed 48,404 requests to Aid Access, an Austria-based nonprofit, for such “advance provision” abortion pills between September 2021 and April 2023. This trend is rising as telehealth services begin offering the option to prepare for potential abortion access restrictions. The study found that demand for these pills, not yet needed for immediate use, spiked during periods when reproductive freedoms seemed threatened. Notably, requests surged following the leak of the Dobbs decision in May 2022, which indicated the potential overturning of Roe v. Wade. Demand increased again with conflicting court decisions in April 2023 about access to mifepristone, a key abortion drug. However, the study also reveals a demographic gap in who accesses advance provision. Compared to those seeking immediate abortion pills, those stockpiling tend to be older, live in lower-poverty areas, are less likely to have children, and are predominantly Caucasian. This highlights a need for greater outreach to ensure equitable access, especially for people of color and those in financial hardship. The study suggests that as barriers to reproductive health care rise, so will the demand for advance provision of abortion medications. (Wired)
A BRAVE NEW WORLD.
Quantum machine learning combines machine learning with quantum computing, a rapidly advancing field. While quantum computers offer the promise of solving problems more efficiently than traditional computers, their applicability to machine learning is still uncertain. Major tech companies and academic institutions are exploring this potential, yet it remains unclear if quantum machine learning surpasses classical methods. Quantum algorithms theoretically could enhance machine learning efficiency, as shown in some studies. However, integrating classical data with quantum processes is challenging and the benefits are not always clear. Some researchers are focusing on quantum phenomena, where quantum machine learning might identify patterns undetectable by classical methods. Quantum sensing, using quantum tools for data collection and analysis, has shown potential, especially in fields like particle physics and astronomy. The true effectiveness of quantum machine learning will be determined through experimentation, rather than solely theoretical analysis. Despite uncertainties and challenges, the field is considered promising and worthy of further exploration. (Nature)

MAPPING THE IMMUNE SYSTEM.
The Human Immunome Project (HIP), commencing this year, aims to establish the most extensive immunological database globally. Spearheaded by an international consortium, HIP seeks to analyze thousands of immune variables in samples from hundreds of thousands of volunteers worldwide. This initiative, estimated to cost between $1 billion to $3 billion over ten years, expands upon previous research, like Amy Huei-Yi Lee’s work, which identified predictors of hepatitis B vaccine response. HIP will address the lack of diversity in immunological studies by collecting baseline data from various global populations. It plans to operate across 300 collection sites, examining a wide range of individuals across different ages and health conditions. The first phase will involve detailed analysis at several clinical research centers. HIP also aims to develop AI models to predict immune responses, aiding in drug development and healthcare management. However, this aspect faces skepticism over its potential impact on understanding the immune system. Challenges include securing funding, standardizing procedures across sites, and addressing the historical mistrust among nonwhite communities towards scientific research. If successful, HIP could significantly enhance our knowledge of human immune systems. (Science)
THE GREAT DINO-DEBATE.
Five years ago, fossil hunters in eastern Montana unearthed a dinosaur with features akin to a Tyrannosaurus rex, but only the size of a pickup truck, sparking debate among paleontologists. This specimen, nicknamed Chomper and now for sale in London for $20 million, raises the question: is it a young T. rex or a different species, Nanotyrannus? The controversy has polarized scientists and spilled into auction houses, where T. rex’s name could command higher prices. The David Aaron gallery labels it a “rare juvenile Tyrannosaurus rex skeleton,” based on a 2020 study analyzing bone growth rings. However, Pete Larson, a renowned fossil expert, argues Chomper is a Nanotyrannus, citing specific physical traits. This debate extends back to 1942 with the discovery of a small dinosaur skull, initially identified as Gorgosaurus but later contested as a juvenile T. rex or Nanotyrannus. The ongoing debate involves multiple specimens, including Jane, a 21-foot-long dinosaur displayed in Illinois. The sale of dinosaur fossils, like the $32 million T. rex Stan, concerns scientists who fear losing access to crucial specimens for research. The resolution to this debate hinges on more specimen studies, but the rising commercial value of dinosaur fossils poses a challenge to academic research. (New York Times)
MOTHER KNOWS BEST?
A group of researchers, led by Syracuse University’s Kristy Buzard, conducted a study titled “Who You Gonna Call?” published in the SSRN Electronic Journal, addressing a common frustration among working mothers: schools predominantly contacting them instead of fathers for child-related issues. This study, focusing on heterosexual parents, revealed a persistent bias where schools default to contacting mothers, even when both parents wish to share responsibilities equally. Through experiments involving emails sent to U.S. school principals, the research found mothers were contacted 1.4 times more than fathers. This trend remained unchanged regardless of the parents’ indicated availability or joint decision-making requests. The findings suggest that schools perceive mothers as more likely to respond or more suited for handling these issues, potentially due to social norms or communication ease. This bias contributes to broader societal issues, such as the gender wage gap, as it influences mothers’ career choices. The researchers advocate for more adaptable school systems and improved information management to distribute parental responsibilities more equitably and efficiently. (CBC)
DESERT KITES DECIPHERED.
Aerial photographs in the 1920s revealed over 6,000 ancient stone wall structures, known as “desert kites,” in Asia and the Middle East, believed to be used for herding and trapping wild animals. Recent research, published in PLoS ONE, has uncovered two stone engravings in Jordan and Saudi Arabia, representing the oldest known plans for these kites, dating back 7,000-8,000 years. These engravings demonstrate sophisticated spatial understanding and planning skills, as they accurately depict the kite structures in scale. The Jordanian engraving features driving lines leading to a star-shaped enclosure with pit traps, while the Saudi Arabian engraving shows similar patterns. These findings suggest that ancient builders had a profound mastery of three-dimensional space and were capable of translating it into scaled two-dimensional representations. The purpose of these engravings could have been for planning hunting strategies or symbolic communication. This discovery highlights a significant advancement in human cognitive and communicative abilities in ancient times. (Ars Technica)
HE’S BIG AND HE’S STRONG.
The Cerne Abbas Giant, a 180-foot figure in Dorset, England, has been a subject of historical mystery. Recent research suggests it represents Hercules, dating from 700 to 1100 C.E., challenging earlier beliefs of a prehistoric origin. This new theory, published in the journal “Speculum,” proposes the Giant as a symbol against Viking invasions, possibly serving as a rallying point for West Saxon armies. The figure’s distinct club and its location near major roads support this interpretation. The study, led by Thomas Morcom and Helen Gittos, also explores the Giant’s cultural evolution, noting how 11th-century monks adapted its pagan image to fit Christian narratives. Today, the Giant remains a significant cultural icon, inspiring new traditions and community identity. This research provides a more integrated understanding of the Giant’s historical and cultural significance, placing it firmly within the context of local history and community life. (Smithsonian)
