WASHINGTON, July 11, 2023 – Compared to artificial tears, or eye drops, human tears are significantly more complex liquids, with a wide range of components including lipids, carbohydrates, proteins, water, and salt. It is this complex mixture that gives tears the perfect thickness and ability to moisturize the eye, a design that is hard to replicate with fewer ingredients. In Physics of Fluids, from AIP Publishing, Vega et al. researched human tears at the micron level to reveal new ways of customizing artificial tears to address individual symptoms of dry eye disease. The detailed insights they gained about the composition and behavior ...

Unborn babies use ‘greedy’ gene from dads to ‘remote-control’ mums into feeding them extra food Fetuses use a copy of a gene inherited from their dad to force their mum to release as much nutrients as possible during pregnancy, Cambridge scientists have discovered. The unborn baby ‘remote controls’ its mother’s metabolism so the two are in a nutritional tug of war. The mother’s body wants the baby to survive but needs to keep enough glucose and fats circulating in her system for her own health, to be able to deliver ...

WASHINGTON, July 11, 2023 – Inspired by the need to safeguard marine animals and promote sustainable solutions within marine environments, an interdisciplinary team of researchers from King Abdullah University of Science and Technology in Saudi Arabia and Sofia University in Bulgaria are delving into the hydrodynamics of buoyant objects at the air-water interface.

Children who experience racial discrimination are more likely to later have a higher body mass index (BMI) and larger waistline, according to a new study published in JAMA Network Open. The findings illustrate that racial discrimination may be a risk factor for young people developing obesity—above and beyond other socioeconomic factors such as family income.   “Exposure to racial discrimination must be acknowledged as both a social determinant of obesity and a significant contributor to obesity disparities among children and adolescents,” said Adolfo Cuevas, assistant professor of social and behavioral sciences at the NYU School of Global Public Health and the study’s ...

BOSTON – The first large-scale U.S. clinical trial of cytisinicline, led by a Massachusetts General Hospital (MGH) investigator, found the smoking cessation medication to be effective and well tolerated in adults who wished to break their nicotine dependence. In the Phase 3 study published in JAMA, researchers reported that cytisinicline could offer adults who smoke a potential new treatment option. “Cigarette smoking remains the leading preventable cause of death worldwide, yet no new smoking cessation medication has been approved by the U.S. Food and Drug Administration for nearly two decades,” says Nancy Rigotti, MD, director of MGH’s ...

BINGHAMTON, N.Y. -- A strange mystic swings a pocket watch back and forth, repeating the phrase “You’re getting sleepy, very sleepy,” giving them absolute command over their subject. That’s not how hypnotism really works, but it’s the way it’s often depicted in pop culture. Even some clinicians and hypnosis educators propagate harmful myths about hypnosis. Steven Jay Lynn, a professor of psychology at Binghamton University, State University of New York, is an expert on hypnosis who has made major contributions to the judicial system ...

(WASHINGTON, July 11, 2023) – As the United States faces a growing obesity epidemic, scientists are taking a closer look at how body weight can affect health outcomes. New research published in Blood Advances highlights the potential association of elevated body mass index (BMI) with inferior outcomes to treatment for acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYAs). This study sheds light on the impact of weight on treatment toxicities and outcomes and calls for further study of the impact of weight on response to different ALL chemotherapy regimens. Obesity is a growing public health threat in the United States, affecting approximately ...

OAK BROOK, Ill. – New CT technology allows for a comprehensive, simultaneous evaluation of lung structure and function, something not possible with standard CT, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA). Chest CT is the imaging method of choice for analyzing lung disease and tracking changes over time. However, CT studies of lung function and perfusion, or blood flow, require dedicated protocols that cannot be combined. Researchers in Germany and the Netherlands developed a chest imaging protocol that yields ...

Moral values such as purity and loyalty are often linked with hateful language, according to a study. Scholars in the field of Natural Language Processing (NLP) have in recent years focused on improving the automated detection of hate speech so such language can be removed from online spaces. But some scholars have argued that mere detection is not a real solution—that NLP can and should be used to investigate the roots of hateful language. Morteza Dehghani and colleagues conducted three studies of hateful language, looking at speeches and texts written by leaders of the Nazi party between 1933 and 1945, hateful slurs ...

An experimental study explores the visible impact flash created by high velocity impacts. Impacts by debris and meteoroids pose a significant threat to satellites, space probes, and hypersonic craft. Such high-velocity impacts create a brief, intense burst of light, known as an impact flash, which contains information about both the target and the impactor. Gary Simpson, K.T. Ramesh, and colleagues explored the impact flash by shooting stainless steel spheres into an aluminum alloy plate, at a speed of three kilometers per second — about 6,700 miles per hour, or more than nine times the speed of sound. The resulting impact flashes were photographed ...

The Xerces Blue butterfly (Glaucopsyche xerces) was native to the coastal dunes of San Francisco, in the United States. As the city grew, much of the butterfly’s habitat was destroyed and its population was relegated to Golden Gate National Park. Its wings were a deep iridescent blue, with characteristic white spots on the ventral side. The last surviving specimens of the species were found in 1941, by entomologist W. Harry Lange. It is considered the first insect species to have become extinct in historical times. Its disappearance has made it a global icon of anthropogenic extinction, to ...

Biologists attempting to conserve and restore denuded environments are limited by their scant knowledge of what those environments looked like before the arrival of humans. This is especially true of coastal ecosystems, many of which had already been drastically altered by pollution and overharvesting hundreds of years before scientists began monitoring them. According to a new study published in the journal PeerJ, a faithful analogue of modern marine ecosystems lies just beneath the surface. Building on more than 20 years of conservation paleobiology, the results suggest that fossils of various marine groups — including worms, mollusks, crabs and sea urchins — are ...

There is a “silent hazard” lurking underneath our major global cities, and our buildings were not designed to handle it. A new Northwestern University study has, for the first time, linked underground climate change to the shifting ground beneath urban areas. As the ground heats up, it also deforms. This phenomenon causes building foundations and the surrounding ground to move excessively (due to expansions and contractions) and even crack, which ultimately affects structures’ long-term operational performance and durability. Researchers also report that past building damage ...

A team led by the Hong Kong University of Science and Technology (HKUST) has developed a technique to study how different fish species interact with each other in a coastal region, a breakthrough that helps explain the complex relationships among marine species and how global warming impacts fish populations.
