Study from School of Neuroscience urges more research into sex differences in depression

Study from School of Neuroscience urges more research into sex differences in depression
2023-08-01
In 2016, recognizing that lack of research in female animals was hampering the success of treatments for mood disorders, the National Institutes of Health (NIH) changed its policy for basic research to include sex as a biological variable for basic research, a move that triggered an explosion of research into sex differences. “Building a strong unbiased foundation of literature will help uncover more effective and sex-specific biomarkers for depression onset and target better treatment,” said Georgia Hodes, assistant professor in the School of Neuroscience, part of the Virginia Tech College of Science. Hodes and co-author Dawson Kropp, a Ph.D. ...

Texas A&M chemists, geologists bond over NSF-funded study of clumped isotopes

Texas A&M chemists, geologists bond over NSF-funded study of clumped isotopes
2023-08-01
Carbon dioxide levels in Earth’s atmosphere — and, consequently, ocean temperatures — are rising. How high and how fast ocean temperatures can rise can be learned from temperature measurements of ancient oceans. At the same time, energy exploration also relies on knowing the thermal history of oil and gas source rocks, which is often difficult to determine. One of the most promising techniques for measuring ancient ocean temperatures and basin thermal histories relies on the co-enrichment of rare heavy oxygen and heavy carbon ...

Minds & eyes: Study shows dementia more common in older adults with vision issues

2023-08-01
Losing the ability to see clearly, and losing the ability to think or remember clearly, are two of the most dreaded, and preventable, health issues associated with getting older. Now, a new study lends further weight to the idea that vision problems and dementia are linked.  In a sample of nearly 3,000 older adults who took vision tests and cognitive tests during home visits, the risk of dementia was much higher among those with eyesight problems – including those who weren’t able ...

North Atlantic Oscillation contributes to ‘cold blob' in Atlantic Ocean

2023-08-01
UNIVERSITY PARK, Pa. — A patch of ocean in the North Atlantic is stubbornly cooling while much of the planet warms. This anomaly — dubbed the "cold blob" — has been linked to changes in ocean circulation, but a new study found changes in large-scale atmospheric patterns may play an equally important role, according to an international research team led by Penn State. “People often think the atmosphere has a very short memory, but here we provide evidence that atmospheric circulation change is significant enough to induce some long-term impact on the climate system,” ...

Multiclonality of estrogen receptor expression in ductal carcinoma in situ (DCIS)

Multiclonality of estrogen receptor expression in ductal carcinoma in situ (DCIS)
2023-08-01
“We have discussed in detail the clinical implications of ER in avoiding overtreatment and undertreatment in DCIS.” BUFFALO, NY- August 1, 2023 – A new editorial paper was published in Oncotarget's Volume 14 on July 20, 2023, entitled, “Multiclonality of ER expression in DCIS – Implications for clinical practice and future research.” Estrogen receptor (ER) expression is not routinely evaluated in ductal carcinoma in situ (DCIS). This may be because the prognostic role of ER in DCIS was unclear until the UK/ ANZ DCIS trial in 2021 showed that lack of ER expression in DCIS was associated with a greater than 3-fold risk of ipsilateral recurrence. This ...

Score, then rank: Researchers propose an integrated approach to grant review assessments

2023-08-01
The public funding of science is responsible for many of the biomedical and other scientific breakthroughs on which our lives depend. However, the process through which funding decisions are made, the peer review of grant proposals, has been historically understudied, and current approaches can lead to undesirable outcomes. Writing in Research Integrity and Peer Review, Stephen A. Gallo, then affiliated with the American Institute of Biological Sciences, and Michael Pearce, Carole J. Lee, and Elena A. Erosheva from the University of ...

A floating sponge could help remove harmful algal blooms

A floating sponge could help remove harmful algal blooms
2023-08-01
In the peak heat of summer, beachgoers don’t want their plans thwarted by harmful algal blooms (HABs). But current methods to remove or kill toxin-producing algae and cyanobacteria aren’t efficient or practical for direct applications in waterways. Now, researchers reporting in ACS ES&T Water have coated a floating sponge in a charcoal-like powder, and when paired with an oxidizing agent, the technique destroyed over 85% of algal cells from lake and river water samples. Swaths of electric green and bright orange-red HABs, or the less brilliantly colored cyanobacteria Microcystis aeruginosa, can produce toxins that can sicken humans ...

Early-life lead exposure linked to higher risk of criminal behavior in adulthood

2023-08-01
An evaluation of 17 previously published studies suggests that exposure to lead in the womb or in childhood is associated with an increased risk of engaging in criminal behavior in adulthood—but more evidence is needed to strengthen understanding. Maria Jose Talayero Schettino of the George Washington University, U.S., and colleagues present these findings in the open-access journal PLOS Global Public Health. Lead exposure can cause a variety of health challenges, such as cardiac issues, kidney ...

Organoids revolutionize research on respiratory infections

Organoids revolutionize research on respiratory infections
2023-08-01
Biofilms are highly resistant communities of bacteria that pose a major challenge in the treatment of infections. While studying biofilm formation in laboratory conditions has been extensively conducted, understanding their development in the complex environment of the human respiratory tract has remained elusive. A team of researchers led by Alexandre Persat at EPFL have now cracked the problem by successfully developing organoids called AirGels. Organoids are miniature, self-organized 3D tissues grown from stem cells to mimic actual body tissues and organs in the human body. They represent ...

The key to battling a pathogen hides in its genome

2023-08-01
Many of the answers for effectively responding to a pathogen lie in its genome. Understanding the genetic code of a pathogen like Ebola or the virus that causes COVID-19 allows scientists to track its movement, predict future behavior, identify the source of the outbreak and, most importantly, develop effective vaccines and treatments. This technology was critical during the pandemic, and it will be even more so with future outbreaks.  That makes the continued development of genomic sequencing one of the most ...

Sex pheromone of moths is a precise mix of ingredients

2023-08-01
Researchers from the UvA and North Carolina State University have identified the specific mixture of pheromone chemicals that male moths use during courtship. The findings provide more detail about the complex blend of chemicals that males and females of this group of moths use in fundamental short-range communication. The publication in the scientific journal Current Biology appeared on 1 August. Scent compounds are essential for male moths to entice female conspecifics to mate. Both partners need to find and recognize each other in the dark. This is done by sex pheromones secreted by the female. Then it is up to the male to convince the female ...

Study characterizes unique immune response in patients who experience inflammatory arthritis as side effect of cancer therapies

2023-08-01
Immune checkpoint inhibitor (ICI) therapies used to treat cancer come with the risk of adverse autoimmune responses, including arthritis that can persist for years and require joint replacement surgery. Little is known about the specific cells responsible for these events. Researchers at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, and collaborators led a study to investigate these immune adverse events and identified a specific type of CD8 T cell that characterizes inflammatory arthritis induced by ICI therapies. Researchers ...

Immigrant nurses in long-term care facilities often have more “human capital” compared to American-born nurses, MU researcher finds

Immigrant nurses in long-term care facilities often have more “human capital” compared to American-born nurses, MU researcher finds
2023-08-01
COLUMBIA, Mo. -- When assessing the skills and competencies or “human capital” of long-term care registered nurses in the United States, studies often focus solely on years of experience and traditional educational backgrounds. However, a new study conducted by a nurse scientist now at University of Missouri found that by incorporating additional criteria, such as ability to speak multiple languages, additional certificates or trainings and licenses to practice in multiple states, immigrant nurses often represent far more human capital than their American-born counterparts. Roy Thompson, a postdoctoral fellow in the MU Sinclair School of Nursing ...

2023-08-01
In a new study published on 21 July 2023 by the journal Bone Research, a team of researchers from Johns Hopkins University, using a combination of lineage tracing and single-cell RNA sequencing (scRNA-seq), delved into the contribution of synovial/tendon sheath progenitor cells to heterotopic bone formation. The researchers identified a distinct population of Tppp3+ tendon progenitor cells that actively participated in the formation of ectopic bone in vivo. Their findings provide new insights into the intricate cellular processes driving heterotopic ossification and offer potential therapeutic targets to prevent and ...

Where Black adolescents live affects their mental health

2023-08-01
It’s easy to imagine that growing up in a neighborhood with safe and clean parks, little to no discrimination, and where people are not struggling financially makes for a lower-stress childhood. In contrast, neighborhoods with few community spaces, violence, and poverty create a higher-stress environment for a child to live in. Unfortunately, systemic and structural issues such as wealth inequality, residential segregation, barriers to home ownership, and environmental injustice in neighborhoods where Black American adolescents disproportionately reside make ...

Irvine, Calif., Aug. 1, 2023 — When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study by University of California, Irvine neuroscientists reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.   The team’s study appears in Frontiers in Neuroscience. ...

Links between attention and conscious perception highlighted in frontoparietal networks

Links between attention and conscious perception highlighted in frontoparietal networks
2023-08-01
Almost half of patients who experienced a stroke in the right cerebral hemisphere later develop a very unusual symptom: they lose the ability to perceive what is happening in the left side of space. As a result, they tend to eat only the right side of their plate, ignore people on their left, and have great difficulty finding their way around. This disorder, known as hemispatial neglect, does not involve basic visual abilities, which remain intact. “These patients see very well. The problem ...
