Should fathers be screened for postpartum depression?
Dads can suffer from postpartum depression, and a new pilot study at the University of Illinois Chicago suggests they can and should be screened for the condition. Given the intertwined effects of mothers' and fathers' physical and mental health, addressing the health of fathers may be a powerful untapped tool in improving the nation's ongoing maternal health crisis.

New strategy for eye condition could replace injections with eyedrops
A new compound developed at the University of Illinois Chicago potentially could offer an alternative to injections for the millions of people who suffer from an eye condition that causes blindness. Wet age-related macular degeneration causes vision loss due to the uncontrolled growth and leakage of blood vessels in the back of the eye.

Hispanics killed by firearms at twice the rate of whites
U-M analysis of data from 38 states shows significant disparities in firearm injury, death rates among Hispanic populations Study: Firearm homicides among Hispanics and white non-Hispanics: Measuring disparities The rate of firearm homicide among Hispanic populations in the United States was more than two times higher than that of white Americans in 2021, the largest disparity in more than a decade, according to new research led by the University of Michigan.

How a single neuron’s parallel outputs can coordinate many aspects of behavior
Study finds that in worms, the HSN neuron uses multiple chemicals and connections to orchestrate egg-laying and locomotion over the course of several minutes. A new MIT study that focuses on a single cell in one of nature's simplest nervous systems provides an in-depth illustration of how individual neurons can use multiple means to drive complex behaviors.

By genetically testing nearly 1,000 embryos, scientists have provided the most-detailed analysis of embryo fate following human in vitro fertilization. Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development-a revealing insight that suggests more IVF babies could come to term with changes in the fertility treatment process.
Incoming Undergrad Is Published in PRL
Amith Varambally of Vestavia Hills, Alabama, comes to Caltech as a first-year undergraduate student in fall 2023 already a co-author of a journal article related to his work as a high school intern at MIT in summer 2022. It is uncommon for undergraduates to publish in STEM journals. Still less common is to see a high school student appearing as a co-author in the pages of an esteemed physics journal.

Metaphors for human fertilization are evolving
While the metaphor of an active sperm and a passive egg has long been used to describe fertilization, a more gender-egalitarian approach is circulating. In a common metaphor used to describe human fertilization, sperm cells are competitors racing to penetrate a passive egg. But as critics have noted, the description is also a -fairy tale- rooted in cultural beliefs about masculinity and femininity.

By focusing on causal relationships in genome regulation, a new AI method could help scientists identify new immunotherapy techniques or regenerative therapies. A strategy for cellular reprogramming involves using targeted genetic interventions to engineer a cell into a new state. The technique holds great promise in immunotherapy, for instance, where researchers could reprogram a patient's T-cells so they are more potent cancer killers.
Is AI in the eye of the beholder?
Study shows users can be primed to believe certain things about an AI chatbot's motives, which influences their interactions with the chatbot. Someone's prior beliefs about an artificial intelligence agent, like a chatbot, have a significant effect on their interactions with that agent and their perception of its trustworthiness, empathy, and effectiveness, according to a new study.

Researchers have developed a scalable AI-based approach that makes use of genetic studies that include people of different ethnic backgrounds and could one day help address health disparities For many diseases and chronic conditions, an individual's genes play a role in their likelihood of developing the disease.
NASA’s Perseverance Captures Dust-Filled Martian Whirlwind
The six-wheeled geologist spotted the twister as part of an atmospheric exploration of Jezero Crater. The lower portion of a Martian dust devil was captured moving along the western rim of Mars' Jezero Crater by NASA's Perseverance rover on Aug. 30, 2023, the 899th Martian day, or sol, of the mission.

Learning critical Black history can change white perspectives on racism in health care
Health + Behavior UCLA study shows it can also spur support for policies aimed at equity Elizabeth Kivowitz September 28, 2023 Key takeaways Two-thirds of white Americans believe that Black Americans do not experience racism or racial inequities in health care. UCLA psychologists exposed white study participants to the well-documented history of medical-related mistreatment of Black Americans.

Accelerating Sustainable Semiconductors With ’Multielement Ink’
Key Takeaways Scientists have developed "multielement ink" - the first "high-entropy" semiconductor that can be processed at low temperature or room temperature. Multielement ink could enable cost-effective and energy-efficient semiconductor manufacturing. The new semiconducting material could accelerate the sustainable production of next-gen microelectronics, photovoltaics, solid state lighting, and display devices.

Addressing Copyright, Compensation Issues in Generative AI
A team in the School of Computer Science's Generative Intelligence Lab collaborated with Adobe Research and the University of California, Berkeley, to develop two algorithms to help generative AI models take important steps on these issues. The first algorithm prevents these models from generating copyrighted materials, while the second develops a way to compensate human creators when models use their work to generate an image.

A research team led by a Yale astronomer has some advice for our next close encounter with a wandering, interstellar object. Check its X-rays on the way out. Since 2017, when a mysterious space rock known as -Oumuamua was spotted passing through Earth's solar system, researchers have become increasingly aware of the likelihood that interstellar objects cross through the solar system with some regularity.
Decoding the complexity of Alzheimer’s disease
By analyzing epigenomic and gene expression changes that occur in Alzheimer's disease, researchers identify cellular pathways that could become new drug targets. Alzheimer's disease affects more than 6 million people in the United States, and there are very few FDA-approved treatments that can slow the progression of the disease.

The sex hormone commonly known as estrogen plays an important role in multiple aspects of women's health and fertility. High levels of estrogen in the body are associated with breast and ovarian cancers, while low levels of estradiol can result in osteoporosis, heart disease, and even depression.
Cosmic Web Lights Up in the Darkness of Space
Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While astronomers have known about the cosmic web for decades, and even glimpsed the glow of its filaments around bright cosmic objects called quasars, they have not directly Galaxies in our universe condense out of swirling clouds of gas.

Improving US air quality, equitably
Study finds climate policy alone cannot meaningfully reduce racial/economic disparities in air pollution exposure. Decarbonization of national economies will be key to achieving global net-zero emissions by 2050, a major stepping stone to the Paris Agreement 's long-term goal of keeping global warming well below 2 degrees Celsius (and ideally 1.

First experimental study to propose a therapy to correct memory deficit caused by disorders in the fetal alcohol spectrum
Research conducted in a mouse model identifies the neurobiological mechanism responsible for alterations in the memory of young individuals exposed to alcohol during pregnancy and lactation. This study proposes a therapy that can reverse the deficit, paving the way for treating a disorder that is underdiagnosed in humans.
