Sugar-coated nanotherapy dramatically improves neuron survival in Alzheimer’s model
2025-05-14
Scientists at Northwestern University have developed a new approach that directly combats the progression of neurodegenerative diseases like Alzheimer’s disease and amyotrophic lateral sclerosis (ALS).
In these devastating illnesses, proteins misfold and clump together around brain cells, which ultimately leads to cell death. The innovative new treatment effectively traps the proteins before they can aggregate into the toxic structures capable of penetrating neurons. The trapped proteins then harmlessly degrade in the body.
The “clean-up” strategy significantly ...
Uncovering compounds that tame the heat of chili peppers
2025-05-14
When biting into a chili pepper, you expect a fiery sensation on your tongue. This spiciness is detected because of capsaicinoid compounds. But for some peppers, despite high levels of capsaicinoids, the heat is mysteriously dull. Now, researchers reporting in ACS’ Journal of Agricultural and Food Chemistry have identified three compounds that lessen peppers’ pungency. These results challenge the reliability of the century-old Scoville scale, which traditionally bases its rating on two capsaicinoids.
“The discovery of natural dietary compounds that reduce pungency presents promising opportunities ...
Astronomers take a second look at twin star systems
2025-05-14
New Haven, Conn. — Apples-to-apples comparisons in the distant universe are hard to come by.
Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years searching for comparable objects and formations to study. And it is rarer still when those objects are side-by-side.
But a new Yale study offers a road map for finding “twin” planetary systems — showing whether binary stars that orbit each other, and that were born at the same time and place, tend to host similar ...

Does adapting to a warmer climate have drawbacks?
2025-05-14
Global warming is already very tough for animals in the wild, but it may be toughest for creatures like fish, whose body temperatures are controlled by the water temperatures around them.
Fish have to evolve to handle higher water temperatures, if they can’t move to areas with colder water. But what if adapting to warmer water has other unwanted consequences?
In a new publication in Nature Climate Change, researchers looked at zebrafish that they had specially bred over 7 generations to tolerate ...

Now, a multi-institutional team led by The University of Osaka has developed and provided proof-of-concept of a new technology to visualize the distribution of components within a single cell, paving the way for a much greater understanding of disease in complex biological samples.
t-SPESI (tapping-mode scanning probe electrospray ionization) is a technique that allows analysis of the spatial layout of molecules in a sample. Multiple micro-samples of different regions of ...
Autistic people communicate just as effectively as others, study finds
2025-05-14
There is no significant difference in the effectiveness of how autistic and non-autistic people communicate, according to a new study, challenging the stereotype that autistic people struggle to connect with others.
The findings suggest that social difficulties often faced by autistic people are more about differences in how autistic and non-autistic people communicate, rather than a lack of social ability in autistic individuals, experts say.
Researchers hope the results of the study will help reduce the stigma surrounding autism, and lead to more effective ...
Alaska: Ancient cave sediments provide new climate clues
2025-05-14
Paul Wilcox, a geologist at the University of Innsbruck, has discovered the first land-based evidence of meltwater pulses from the Cordilleran Ice Sheet during the last ice age about 20,000 years ago. The age of the cave sediments was constrained via optical dating techniques, which is crucial to help piece together the sequence of climate events leading to a warming planet. The results were published in the journal Nature Geoscience.
Around 20,000 years ago, the Cordilleran Ice Sheet in western North America reached its maximum extent. This was followed by warming climate conditions, causing the ice-sheet to melt. While it is generally accepted ...
Adult-onset type 1 diabetes increases risk of cardiovascular disease and death
2025-05-14
A new study in the European Heart Journal shows that people who develop type 1 diabetes in adulthood have an increased risk of cardiovascular disease and death, and that those diagnosed later in life do not have a better prognosis than those diagnosed earlier. The study, conducted by researchers at Karolinska Institutet in Sweden, points to smoking, poor glucose control and obesity as the main risk factors.
Type 1 diabetes used to be called childhood diabetes but can start at any time during life. However, research on adult-onset type 1 diabetes is limited. The researchers behind the current study wanted to investigate the ...

Chimpanzees use medicinal leaves to perform first aid
2025-05-14
Scientists studying chimpanzees in Budongo Forest, Uganda, have observed that these primates don’t just treat their own injuries, but care for others, too — information which could shed light on how our ancestors first began treating wounds and using medicines. Although chimpanzees elsewhere have been observed helping other community members with medical problems, the persistent presence of this behavior in Budongo could suggest that medical care among chimpanzees is much more widespread than we realized, and not confined ...

Manitoba Museum and ROM palaeontologists discover 506-million-year-old predator
2025-05-14
Palaeontologists at the Manitoba Museum and Royal Ontario Museum (ROM) have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. The results are announced in a paper in the journal Royal Society Open Science.
Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group known as the radiodonts, which also included the famous Anomalocaris canadensis, a meter-long predator that shared ...
Not all orangutan mothers raise their infants the same way
2025-05-14
A new study of wild Sumatran orangutans by researchers at the Max Planck Institute of Animal Behavior (MPI-AB) has found that mothers consistently differ in their maternal behaviors toward their infants, even after controlling for biological, social, and environmental factors. Mothers also consistently vary from one another in how flexibly they adjust their parenting as their infants grow. For this study, the researchers analysed data on six maternal behaviors collected over 15 years.
“Our study shows that Sumatran orangutan mothers are not all the same when it comes to parenting behaviors,” said Revathe Thillaikumar, a postdoctoral researcher at MPI-AB and ...
CT scanning helps reveal path from rotten fish to fossil
2025-05-14
Scientists have found that X-Ray scanning reveals secrets of fossil formation without disturbing the decay of buried carcasses
A new study published in Palaeontology has confirmed that X-ray computed tomography (XCT scanning) can be used to monitor decomposing organisms without altering the natural decay process – a vital step for understanding how fossils form.
A research team from the University of Birmingham entombed dead zebrafish within sediment to test whether repeatedly zapping decaying specimens with X-rays would change how they decompose. Their findings suggest this non-invasive imaging technique allows scientists to watch decay happen in real-time without disturbing ...
Physical activity + organized sports participation may ward off childhood mental ill health
2025-05-13
Physical activity in early childhood, especially taking part in organised sports,may ward off several mental health disorders in later childhood and adolescence, suggests research published online in the British Journal of Sports Medicine.
But there seem to be clear sex differences in the observed protective effects, depending on the condition, the findings indicate.
The prevalence of mental ill health among children and teens has risen sharply worldwide, with a heightened vulnerability to stress thought to partially explain the increase, note the researchers.
Physical activity ...

Recognition from colleagues helps employees cope with bad work experiences
2025-05-13
Being appreciated by colleagues can help employees cope with negative experiences at work, according to a new study involving the University of East Anglia (UEA).
Researchers found that employees experience ‘embitterment’ - an emotional response to perceived workplace injustice - on days when they are assigned more unreasonable tasks than usual.
This negative emotion not only affects their work but also spills over into their personal lives, leading to an increase in rumination, the repetitive dwelling on negative feelings and their causes. ...
