ABORTION DEBATE INTENSIFIES, SHAPING VOTERS AND POLICY Since the Supreme Court overturned Roe v. Wade, public discourse around abortion has intensified, emphasizing its complex implications on health care. The focus has expanded from the availability of abortions to critical issues faced during pregnancy complications under restrictive laws. The narrative has shifted, highlighting the real-life consequences of abortion bans, such as women being forced to cross state lines for necessary medical procedures. This has influenced public opinion, with a significant rise in Americans, especially amon ..read more

7h ago
A new study led by Dr. Shir Atzil and her team from the Department of Psychology at the Hebrew University unveils intriguing insights into the mechanisms of romantic bonding, focusing particularly on physiological synchrony—the alignment of physiological responses between individuals—and its impact on perceived romantic attraction. Physiological synchrony refers to the alignment of physiological responses between individuals. This can include parameters like heart rate, respiration, and skin conductance. When two people are physiologically in sync, their bodily functions align in a w ..read more

10h ago
A study published today in the journal BioScience sheds light on the importance of gray wolves in western United States. Led by William Ripple, a scientist at Oregon State University and the Conservation Biology Institute, the research delves into the implications of large predator absence on plant and animal communities, and ecosystem functions. It calls attention to “shifting baselines” wherein increasingly degraded conditions are viewed as reflecting the historical state of a system. “By the 1930s, wolves were largely absent from the American West, including its national parks.

by scientificinquirer
15h ago
Between July and October 2023, highly pathogenic avian influenza (HPAI) A(H5N1) was detected in animals on 27 fur farms in Finland. The outbreak, traced to wild birds, revealed significant virus adaptation to mammals. The virus caused severe inflammation in animals’ lungs, brains, and livers. Further genetic analyses identified three viral clusters, with mutations facilitating mammalian adaptation. Epidemiological Investigation The outbreak likely originated from extensive exposure of fur animals to infected wild birds, given the high number of wild bird deaths in the surrounding areas. The vi ..read more

A team of international scientists led by the University of Ottawa have gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states. Professor Jean-Michel Ménard, leader of the Ultrafast Terahertz Spectroscopy group at the Faculty of Science, coordinated with Dr. Claudiu Genes at the Max Planck Institute for the Science of Light (Germany), and with Iridian Spectral Technologies (Ottawa) to design a device which can efficiently modify properties of materials using the quantum superposition with light. The team d ..read more

Sunlight and Plastic: A Hazardous Mix for Bottled Water Safety
Scientific Inquirer

18h ago
A new study delves into the potential health risks posed by the release of volatile organic compounds (VOCs) from plastic water bottles when exposed to sunlight. The research, which systematically examined the composition and toxicity of VOCs emitted under ultraviolet-A (UV-A)  and solar irradiation, underscores the need for safer storage practices to ensure drinking water safety. Plastic water bottles are ubiquitous due to their convenience, yet they harbor potential risks. Sunlight exposure can lead these containers to degrade and emit volatile organic compounds (VOCs), which are potent ..read more

21h ago
Insecticide use is a major factor causing a decrease in the size and diversity of butterfly populations across the US Midwest, reports Braeden Van Deynze of the Washington Department of Fish and Wildlife and colleagues in a new study published June 20 in the open-access journal PLOS ONE. Like many insects, butterfly populations worldwide are in decline. Experts have pointed to habitat loss, climate change and pesticides as likely factors contributing to the problem, but the primary drivers of this troubling trend remain murky. In the new study, researchers analyzed 17 years of data on lan ..read more

Early Solar System Resembled a Doughnut, Iron Meteorites Reveal
Scientific Inquirer

1d ago
Four and a half billion years ago, our solar system was a cloud of gas and dust swirling around the sun, until gas began to condense and accrete along with dust to form asteroids and planets. What did this cosmic nursery, known as a protoplanetary disk, look like, and how was it structured? Astronomers can use telescopes to “see” protoplanetary disks far away from our much more mature solar system, but it is impossible to observe what ours might have looked like in its infancy — only an alien billions of light years away would be able to see it as it once was. Fortunately, space has dropped a ..read more

Controlling electronics with light: the magnetite breakthrough
Scientific Inquirer

2d ago
“Some time ago, we showed that it is possible to induce an inverse phase transition in magnetite,” says physicist Fabrizio Carbone at EPFL. “It’s as if you took water and you could turn it into ice by putting energy into it with a laser. This is counterintuitive as normally to freeze water you cool it down, i.e. remove energy from it.” Now, Carbone has led a research project to elucidate and control the microscopic structural properties of magnetite during such light-induced phase transitions. The study discovered that using specific light wavelengths for photoexcitation the sys ..read more

After ISIS bombs, an urgent call to preserve an ancient Syrian temple
Scientific Inquirer

2d ago
The Temple of Bel stands in the ancient Syrian city of Palmyra, adjoining a desert oasis with palm trees and bountiful water. Constructed in the first two centuries of the Common Era, the temple served for nearly two thousand years as a sanctuary for locals and as a site of significant archaeological interest. In 2015, the temple was destroyed by ISIS explosives. In “The Future of the Temple of Bel in Palmyra after its Destruction,” a new paper from the Bulletin of ASOR, authors Maamoun Abdulkarim and Jacques Seigne argue for the urgent need to intervene in the restoration of the temple ..read more
