Exploration of polymer cononsolvency mechanism through soft X-ray absorption spectroscopy
2024-05-17
This study investigates the cononsolvency mechanism of poly(N-isopropylacrylamide) (PNIPAM), which is soluble in pure methanol (MeOH) and water but insoluble in aqueous MeOH solutions. Combining oxygen K-edge X-ray absorption spectroscopy (XAS) with theoretical calculations executed in molecular dynamics (MD) simulations and inner-shell calculations, it was found that hydrophobic interactions between PNIPAM and MeOH clusters play a key role in PNIPAM aggregation and cononsolvency emergence.
PNIPAM is ...

USC researcher awarded $3.1 million to study early brain development of babies born to mothers with diabetes in pregnancy
2024-05-17
It has long been understood that pregnant women with diabetes are more likely to have children with obesity than women who do not have diabetes during pregnancy. But scientists have not fully understood the cause or why babies born to mothers with diabetes are also more likely to develop obesity and associated metabolic disorders later in life.
To help find answers, Keck School of Medicine of USC researcher Shan Luo, PhD, has been awarded $3.1 million in funding from the National Institutes of Health and the National Institute of Diabetes ...
Men at greater risk of major health effects of diabetes than women
2024-05-17
Men are at greater risk than women of the major health effects of diabetes (types 1 and 2), suggests a long term study published online in the Journal of Epidemiology & Community Health.
Rates of cardiovascular disease, leg, foot, and kidney complications, and the sight-threatening eye disease diabetic retinopathy are all higher in men, regardless of whether they had diabetes for more or less than 10 years, the findings show.
The global prevalence of diabetes is similar in men and women, and is projected to rise to 783 million by 2045, note the researchers.
But ...
Likelihood of kids and young people smoking and vaping linked to social media use
2024-05-17
The more time spent on social media, the greater the likelihood that children and young people will both smoke and/or vape, suggests research published online in the respiratory journal Thorax.
Clocking up a weekday tally of 7 or more hours was associated with a more than a doubling in risk among 10 to 25 year olds, the findings indicate, reinforcing concerns about the marketing clout of these platforms, say the researchers.
The existing body of research on social media use and smoking and ...

A new ‘rule of biology’ may have come to light, expanding insight into evolution and aging
2024-05-17
By Darrin S. Joy
A molecular biologist at the USC Dornsife College of Letters, Arts and Sciences may have found a new “rule of biology.”
A rule of biology, sometimes called a biological law, describes a recognized pattern or truism among living organisms. Allen’s rule, for example, states that among warm-blooded animals, those found in colder areas have shorter, thicker limbs (to conserve body heat) than those in hotter regions, which need more body surface area to dissipate heat.
Zoologist Joel Allen formulated this idea in 1877, and though he wasn’t the first or the last to present a rule of biology, his ...
Scripps Research chemists develop new method for making gamma chiral centers on simple carboxylic acids
2024-05-17
LA JOLLA, CA—Scripps Research chemists have accomplished a long elusive feat in synthetic chemistry: the invention of a broadly useful method for constructing “gamma chiral centers” on simple starting compounds called carboxylic acids. The method, published on May 16, 2024 in Science, significantly extends the ability of chemists to build and modify complex pharmaceutical molecules and other valuable chemical products.
The term chiral refers to a type of asymmetry that allows some chemical compounds to exist in left-handed and right-handed forms. Often, only one of these forms has the ...

Detecting influence campaigns on X with AI and network science
2024-05-16
In the age of generative-AI and large language models (LLMs), massive amounts of inauthentic content can be rapidly broadcasted on social media platforms. As a result, malicious actors are becoming more sophisticated, hijacking hashtags, artificially amplifying misleading content, and mass resharing propaganda.
These actions are often orchestrated by state-sponsored information operations (IOs), which attempt to sway public opinion during major geopolitical events such as the US elections, the Covid-19 pandemic, and more.

Offering both colonoscopy and at-home tests doubled colorectal cancer screening
2024-05-16
The rate of colorectal cancer screenings more than doubled when patients were given a choice between which type of screening they wanted—a take-home kit or colonoscopy—compared to those who were only offered the colonoscopy, according to new research led by the Perelman School of Medicine at the University of Pennsylvania. Facilitated through a community health center in which about half of patients had Medicaid insurance, the study—published in Clinical Gastroenterology and Hepatology—provides insights about how to boost screenings among groups ...
A powerful tool speeds success in achieving highly efficient thermoelectric materials
2024-05-16
HOUSTON, May 16, 2024 – Thermoelectric materials could play an important role in the clean energy transition, as they can produce electricity from sources of heat that would otherwise go to waste without generating additional greenhouse gases or requiring large up-front investment. But their promise has been slowed by the fact that most current thermoelectric materials don’t efficiently produce enough power to be useful for many practical applications.
The search for new, more efficient materials involving complex chemical ...

Normothermic perfusion system extends life of organs waiting for transplant
2024-05-16
In the United States, about 30-40% of donor hearts aren't considered for transplant due to inadequate function in the donor.
This creates a drop in the number of donated hearts that are available to be matched with someone who needs a heart transplant.
A team at University of Michigan Health led by Alvaro Rojas-Pena, M.D., a research investigator with the section of transplantation surgery at University of Michigan Health has spent the past eight years looking at better ways to transport organs for donation, specifically hearts, to improve the number of organs ...
Study: Large language models can’t effectively recognize users’ motivation, but can support behavior change for those ready to act
2024-05-16
CHAMPAIGN, Ill. — Large language model-based chatbots have the potential to promote healthy changes in behavior. But researchers from the ACTION Lab at the University of Illinois Urbana-Champaign have found that the artificial intelligence tools don’t effectively recognize certain motivational states of users and therefore don’t provide them with appropriate information.
Michelle Bak, a doctoral student in information sciences, and information sciences professor Jessie Chin reported their research in the Journal of the American Medical Informatics Association.
Large language model-based chatbots — also known as generative conversational agents ...
In September, securities watchdogs bark more, bite less
2024-05-16
AUSTIN, Texas -- The Securities and Exchange Commission acts as Wall Street’s traffic cop, fining companies for such infractions as securities fraud and insider trading. New research from Texas McCombs finds another parallel between the SEC and traffic enforcement: pressure to meet self-imposed quotas.
Assistant accounting professors Matthew Kubic and Sara Toynbee find that the agency files twice as many enforcement cases in September as in other months, a phenomenon they call the September spike. They also link the increase in cases to smaller fines that reduce what the government takes in from violators.
The reason for the ...

Under stress, an observer is more likely to help the victim than to punish the perpetrator
2024-05-16
Being stressed while witnessing injustice may push your brain towards altruism, according to a study published on May 14th in the open-access journal PLOS Biology by Huagen Wang from Beijing Normal University, China, and colleagues.
It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender. This aligns with theories proposing that distinct brain networks drive intuitive, fast decisions and deliberate, slow decisions, ...
