Cells in the ear that may be crucial for balance
Mouse study reveals a strong link between a type of hair cell in the inner ear and the ability to balance and orient oneself.
2026-02-09
(Press-News.org) Led by Mathieu Beraneck, researchers at the University of Paris Cité/CNRS and the University of Barcelona explored the strength of the relationship between a type of inner hair cell in the ear and balance. Their work is published in eNeuro. Says Beraneck, “After 200 years of research on this system, still no one has demonstrated the quantity of hair cells necessary for balance, so our study is a first step in answering this long-standing question.”
Using mice, the researchers assessed how sensitive balancing and orienting abilities are to the loss of a subtype of inner hair cells. “Normal” functioning of organs that enable balance required 80% of these hair cells, whereas the presence of 50% of these hair cells supported minimal functioning of these organs.
Speaking on treatment implications, Beraneck emphasizes that this work suggests it may be possible to improve balance by restoring this hair cell population in the inner ear through interventions such as gene therapy. “A conservative target should be to restore at least 50% of inner hair cells. What remains to be seen is the specific role of another type of hair cell that we did not examine, but, in our hands, it looks like the part of the system we investigated is very dependent on the subtype we assessed and targeted.”

Hyesang Chang and colleagues, from Stanford University, explored why some children struggle to learn math compared to their peers in a new JNeurosci paper.
Children selected which numbers were bigger than others across different trials, with quantities represented as numerical symbols or as clusters of dots. The researchers created a model based on how much performance varied over time. The model suggested that children with difficulties in learning math struggled to ...

On a simple math task — indicating which of two amounts is greater — kids with math learning disability get the right answer as often as their good-at-math peers, but behind the scenes, their brains are working differently, a new Stanford Medicine study has found. The differences shed light on what causes their math struggles.
The findings, which will be published online Feb. 9 in the Journal of Neuroscience, show that children with a math learning disability are less likely to solve problems at the right speed, or to slow down after they make mistakes, particularly ...

BOSTON — Dana-Farber Cancer Institute-led research helped drive an FDA label update for axicabtagene ciloleucel (Yescarta) that removes a prior exclusion for patients with primary central nervous system lymphoma, a rare and aggressive lymphoma of the brain and spinal cord. The change is expected to expand access to commercial CAR T-cell therapy for eligible patients with relapsed or refractory disease.
The updated labeling reflects years of Dana-Farber research focused on defining whether CD19-directed CAR T-cell therapy can be delivered safely and effectively to patients with lymphoma involving the central nervous system. Most CAR T-cell trials ...

For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that idea.
A study led by SDU-biologists at the Department of Biology shows that nutrients might not be so sparse after all in the deep and that microbes have access to a hitherto unknown source of dissolved organic food.
The study shows that sinking organic particles—known as marine snow—begin to leak dissolved carbon and nitrogen when they reach depths of 2–6 kilometres, presenting microbes in the surrounding seawater with nutrients. The leakage is caused ...

About The Study: This study found that greater consumption of caffeinated coffee and tea was associated with lower risk of dementia and modestly better cognitive function, with the most pronounced association at moderate intake levels.

As glaciers around the world melt at unprecedented rates, tourism in these icy landscapes is booming, adding pressure to vulnerable regions and disrupting delicate ecosystems. A collective effort, led by UNIL and published in Nature Climate Change, points to ways of balancing tourism with conservation, awareness, and social equity.
Since the 18th century, glaciers have captivated mountaineers, scientists, and nature enthusiasts alike. In recent years, this tourist interest has surged, fueled by media coverage of their decline due to climate change. Each year, over 14 million visitors (drawn by fascination, scientific curiosity, and ecological mourning) travel to ...

Why melting glaciers are drawing more visitors and what that says about climate change
As glaciers around the world continue to shrink and disappear, they are drawing more visitors than ever, not only for their beauty but for what they have come to represent in an era of climate change. A new study co-authored by Rice University anthropologist Cymene Howe examines this phenomenon, showing how melting glaciers have become powerful destinations for tourism, sites of collective grief and symbols of political meaning even as their loss threatens the communities that depend on them.
Published in Nature Climate Change, the paper draws on global case studies to examine how glaciers now ...

Mount Sinai researchers have identified a cellular mechanism linking infections from influenza A viruses (IAVs) to cardiovascular disease, providing critical insights on how influenza can damage the heart and increase the risk of a heart attack or other major cardiovascular event.
Through its work with mouse models and human data, the team also provided evidence that a cutting-edge modified mRNA treatment that dampens an interferon signaling pathway in the heart can significantly mitigate cardiac damage following viral infection while preserving the protective antiviral response of the immune system. The study was published in the February 9 issue of Immunity.

PROVIDENCE, R.I. [Brown University] — A long-standing Medicare policy meant to manage rehabilitation services in nursing homes may keep older Americans in hospitals longer than necessary without improving patient health or saving Medicare money, new research finds.
Established in 1965, the rule was intended to manage the use of skilled nursing facilities, which provide short-term medical and rehabilitative care to Medicare beneficiaries. Known as the “three-day rule,” it requires patients to spend at least three consecutive ...
