For video-on-demand platforms, release strategy matters: streaming episodes gradually boosts consumers’ searches, subscription rates
2025-09-08
The market for video-on-demand platforms has grown rapidly in the last decade, with nearly 90% of U.S. households subscribing to a service, and most subscribers having four or more platforms. In this context, and as more than a third of U.S. subscribers cancel their subscriptions within short periods, retaining subscribers and maximizing engagement have become crucial to the industry.
In a new study, researchers examined how the release strategy of shows—gradually or all at once—influences users’ engagement and subscription rates at a video-on-demand platform. The study found that each approach has its merits, but that gradually releasing shows boosts consumers’ ...
Sleep strengthens muscle and bone by boosting growth hormone levels. Here's how
2025-09-08
As every bodybuilder knows, a deep, restful sleep boosts levels of growth hormone to build strong muscle and bone and burn fat. And as every teenager should know, they won't reach their full height potential without adequate growth hormone from a full night's sleep.
But why lack of sleep — in particular the early, deep phase called non-REM sleep — lowers levels of growth hormone has been a mystery.
In a study published in the current issue of the journal Cell, researchers from University ...

Children receiving biofeedback speech therapy improved faster than with traditional methods
2025-09-08
Run. Red. World. Pronouncing the “r” sound in these words requires precise control of the tongue. For most children, this happens naturally, but many children struggle with residual speech sound disorder (RSSD) in which speech errors persist past the age of eight.
In a large-scale study, researchers in speech pathology tested a promising treatment approach that incorporates biofeedback—a method that uses technology to provide visual feedback to improve speech. They found that children’s ability to say the “r” sound improved at a ...
Scientists discover why the flu is more deadly for older people
2025-09-08
Scientists have discovered why older people are more likely to suffer severely from the flu, and can now use their findings to address this risk.
In a new study, which is published in PNAS, experts discovered that older people produce a glycosylated protein called apoplipoprotein D (ApoD), which is involved in lipid metabolism and inflammation, at much higher levels than in younger people. This has the effect of reducing the patient’s ability to resist virus infection, resulting in a more serious disease outcome.
The team established that highly elevated ApoD production ...
The salmon superfood you’ve never heard of
2025-09-08
In northern California, salmon are more than just fish—they’re a cornerstone of tribal traditions, a driver of tourism and a sign of healthy rivers. So it may not come as a surprise that NAU and University of California Berkeley scientists working along the region’s Eel River have discovered a micro-scale nutrient factory that keeps rivers healthy and allows salmon to thrive.
The scientists’ new study in Proceedings of the National Academy of Sciences (PNAS) reveals how a partnership ...
How does chemotherapy disrupt circadian rhythms?
2025-09-08
During and after chemotherapy, nearly half of cancer patients endure circadian rhythm disruptions, which worsens treatment side effects. Because the body’s primary rhythm pacemaker is in the brain, this suggests that perhaps chemotherapeutics target the brain to disrupt circadian rhythms. However, research shows that cancer treatments do not penetrate the brain well. To shed light on this discrepancy, researchers led by Leah Pyter at Ohio State University explored whether paclitaxel, a frequently used breast cancer treatment, disrupts the biological clock in the brain to impair circadian rhythms.
In their eNeuro paper, the researchers used a paclitaxel treatment regimen ...
A new bystander effect? Aggression can be contagious when observing it in peers.
2025-09-08
People who repeatedly observe aggression have a higher likelihood of engaging in violent behavior later in life. In a new JNeurosci paper, Jacob Nordman and colleagues, from Southern University of Illinois School of Medicine, used mice to explore the environmental factors and neural mechanisms that lead to the aggression that witnesses later acquire.
In a behavioral paradigm created by this research group, mice observed known peers or unfamiliar strangers attack intruder mice. Only male witnesses later displayed increased aggression themselves, and this happened only after watching familiar peers attack intruders.
What neural mechanism might be driving ...
Do you see what I see? People share brain responses for colors.
2025-09-08
Do colors trigger unique brain responses? And do different people have the same brain responses to colors? In a new JNeurosci paper, Michael Bannert and Andreas Bartels, from the University of Tübingen, explored color representation in the human brain to address these questions.
The researchers measured color-induced brain responses from one set of participants. Next, they predicted what colors other participants were observing by comparing each individual’s brain activity to color-induced responses of the first set of observers. Bannert and Bartels found that ...
Blood test could streamline early Alzheimer's detection
2025-09-08
In a landmark study of Hispanic and Latino adults, researchers at University of California San Diego School of Medicine have identified a link between self-reported cognitive decline and blood-based biomarkers, which could pave the way for a simple blood test to help diagnose Alzheimer’s disease and related dementias. This approach could be faster, less-invasive and more affordable than existing screening tools. The results are published in JAMA Network Open.
“We need ways to identify underlying neurodegenerative ...

Young children are not the main drivers of language change
2025-09-08
Theoretical study by Limor Raviv, Damian Blasi and Vera Kempe, argues that children are not likely to be the main force behind linguistic innovation.
For more than a century, scholars have repeated a powerful idea: that the mistakes children make when learning to speak are the seeds of language change. From 19th-century linguist Henry Sweet’s famous claim that “if languages were learnt perfectly by the children of each generation, then languages would not change,” to contemporary studies, the notion that children drive language evolution has been ...

Ocean warming puts vital marine microbe Prochlorococcus at risk
2025-09-08
Among the tiniest living things in the ocean are a group of single celled microbes called Prochlorococcus. They are cyanobacteria, also known as blue-green algae, and they supply nutrients for animals all the way up the food chain. Over 75% of surface waters teem with Prochlorococcus, but as ocean temperatures rise, researchers fear that the water might be getting too warm to support the population.
Prochlorococcus is the most abundant photosynthesizing organism in the ocean, accounting for 5% of global photosynthesis. Because Prochlorococcus thrive in the tropics, researchers predicted that they would adapt ...
Nicotine pouches may offer path to reduced tobacco harm, Rutgers study finds
2025-09-08
As lawmakers and public health experts debate the safety of nicotine pouches, researchers from Rutgers Health found that for now, most adults that use these products also have a history of tobacco use and may be choosing these products as a possible step toward reducing or quitting more dangerous forms of nicotine delivery.
The findings – believed to be the first national estimates of daily nicotine pouch use in the U.S. – were published in JAMA Network Open.
Faced with declining cigarette sales, tobacco manufacturers in the U.S. are turning to tobacco-free nicotine ...
Duke-NUS study reveals how dengue rewires the immune system, reshaping vaccine response
2025-09-08
SINGAPORE, 8 SEPTEMBER 2025—Just as a computer’s operating system can be rewritten after a major update, dengue infection can ‘re-programme’ the body’s immune system, leaving a long-lasting genetic imprint that influences how people respond to future infections—an effect not seen with vaccination.
These novel insights from a recent study shed light on the mechanics of dengue disease progression and vaccine action, filling an important knowledge gap on how even imperfect vaccines can be used safely. It also paves the way for the future development of safer and ...

Seaweed snare: Sargassum stops sea turtle hatchlings in their tracks
2025-09-08
Every year, sea turtles hatch on Florida’s beaches and make their way from the sand to the ocean – a critical journey that determines their chances of survival. As these hatchlings navigate obstacles such as artificial lights, beach debris and predators like birds and crabs, a new hazard looms. Sargassum seaweed washing up on Florida’s shores in record amounts is more than just a nuisance for beachgoers – it’s becoming a serious threat to vulnerable sea turtle hatchlings.
While it’s long been known that obstacles on the beach can slow down hatchlings and put ...
Scientists uncover key to decoupling economic growth from pollution in developing countries
2025-09-08
Balancing environmental conservation with economic progress is one of the most pressing challenges of our time. This is particularly difficult for many developing countries, which urgently need to lift their populations out of poverty while grappling with the increasing degradation of their environment. Unfortunately, a common belief is that these nations have to choose between economic growth and a clean environment—a situation made more complex by their reliance on foreign aid.
While the United Nations Sustainable Development Goals provide a global roadmap for tackling such issues, ...
