- 20/3/25 21:11
Students who used immersive virtual reality (VR) did not learn significantly better than those who used two more traditional forms of learning, but they vastly preferred the VR to computer-simulated and hands-on methods, a new study has found.
Solving a 50-year-old puzzle in signal processing
- ScienceDaily
- 20/3/25 21:11
The same engineers, who announced the solution to a 50-year-old puzzle in signal processing last fall, have followed up with more research results. The engineers say their new algorithm is more useful and just as fast as the one previously used.
An aspirin a day does not keep dementia at bay
- ScienceDaily
- 20/3/25 21:11
Taking a low-dose aspirin once a day does not reduce the risk of thinking and memory problems caused by mild cognitive impairment or probable Alzheimer's disease, nor does it slow the rate of cognitive decline, according to a large study.
A small forage fish should command greater notice, researchers say
- ScienceDaily
- 20/3/25 20:41
A slender little fish called the sand lance plays a big role as 'a quintessential forage fish' for puffins, terns and other seabirds, humpback whales and other marine mammals, and even bigger fish such as Atlantic sturgeon, cod and bluefin tuna in the Gulf of Maine and northwest Atlantic Ocean. But scientists say right now they know far too little about its biology and populations to inform...

Researchers find that a motorized device that attaches around the ankle and foot can drastically reduce the energy cost of running.
Bats depend on conspecifics when hunting above farmland
- ScienceDaily
- 20/3/25 20:40
Common noctules -- one of the largest bat species native to Germany -- are searching for their fellows during their hunt for insects above farmland. Scientists show that bats forage on their own in insect-rich forests, but hunt collectively in groups over insect-poor farmland.

Researchers have discovered that rocaglate compounds are capable of killing Candida auris. The study offers hope of finding a treatment for this troubling, emerging pathogen.
Eclectic rocks influence earthquake types
- ScienceDaily
- 20/3/25 20:40
New Zealand's largest fault is a jumble of mixed-up rocks of all shapes, sizes, compositions and origins. According to research from a global team of scientists, this motley mixture could help explain why the fault generates slow-motion earthquakes known as 'slow slip events' as well as destructive, tsunami-generating tremors.
Ultrasound solves an important clinical problem in diagnosing arrhythmia
- ScienceDaily
- 20/3/25 19:38
Researchers have used an ultrasound technique they pioneered a decade ago -- electromechanical wave imaging (EWI) -- to accurately localize atrial and ventricular cardiac arrhythmias in adult patients in a double-blinded clinical study. They evaluated the accuracy of EWI for localization of various arrhythmias in all four chambers of the heart prior to catheter ablation: the results showed that...

A new study found no virus in tears of COVID-19 infected patients.
Making 3D cameras easier to use
- ScienceDaily
- 20/3/25 19:38
Mechanical engineers are working to compress 3D camera files and automate focus and exposure settings.
Computational human cell reveals new insight on genetic information processing
- ScienceDaily
- 20/3/25 19:38
Researchers have developed the first computational model of a human cell and simulated its behavior for 15 minutes -- the longest time achieved for a biological system of this complexity. In a new study, simulations reveal the effects of spatial organization within cells on some of the genetic processes that control the regulation and development of human traits and some human diseases.
Too much salt weakens the immune system
- ScienceDaily
- 20/3/25 19:38
A high-salt diet is not only bad for one's blood pressure, but also for the immune system. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human volunteers who consumed additional six grams of salt per day also showed pronounced immune deficiencies. This amount corresponds to the salt content of two fast food meals.
Heat takes its toll on mental health
- ScienceDaily
- 20/3/25 19:38
Hot days increase the probability that an average adult in the US will report bad mental health, according to a new study.
Diet, nutrition have profound effects on gut microbiome
- ScienceDaily
- 20/3/25 18:15
A new literature review suggests that nutrition and diet have a profound impact on the microbial composition of the gut.
Here be dragons: Analysis reveals new species in 'Smaug' lizard group
- ScienceDaily
- 20/3/25 18:15
Smaug, the deadly dragon in J.R.R Tolkien's 'The Hobbit,' has a newly discovered living relative. With dense, alligator-like armor, this small, real-life dragon lizard, Smaug swazicus, is a rock-crevice recluse confined to mountaintops in southern Africa.
Analysis predicts purified fish oil could prevent thousands of cardiovascular events
- ScienceDaily
- 20/3/25 18:15
Researchers have conducted a statistical analysis that predicts more than 70,000 heart attacks, strokes and other adverse cardiovascular events could be prevented each year in the U.S. through the use of a highly purified fish oil therapy.
Printing complex cellulose-based objects
- ScienceDaily
- 20/3/25 18:07
Researchers have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-based parts. To achieve this, they used a clever trick.
To stay positive, live in the moment -- but plan ahead

A recent study finds that people who balance living in the moment with planning for the future are best able to weather daily stress without succumbing to negative moods.
Ultrafast repeated staining and destaining of cell samples for tumor diagnostics
- ScienceDaily
- 20/3/25 17:08
In the treatment of tumors, microenvironment plays an important role. It often contains immune cells that are so changed that they promote tumor growth. Scientists have introduced a method by which cell samples from tumors and their surroundings can rapidly (under 1 hour) be cycled through staining, destaining, and then restaining with fluorescent antibodies -- through attachment of a ''black hole...

Researchers have developed a nanodevice that operates more than 10 times faster than today's fastest transistors. It enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications. The high-power picosecond operation of these device...
International ozone treaty stops changes in Southern Hemisphere winds
- ScienceDaily
- 20/3/25 17:08
The Montreal Protocol of 1987 phased out production of ozone-destroying substances such as chlorofluorocarbons (CFCs). Beginning around 2000, concentrations of those chemicals in the stratosphere started to decline and the ozone hole began to recover. In this study, researchers have shown that around the year 2000, the circulation of the Southern Hemisphere also stopped expanding polewards -- a...
Mother/infant skin-to-skin touch boosts baby's brain development and function
- ScienceDaily
- 20/3/25 16:09
As the world prioritizes social distancing due to COVID-19, research shows that extended use of Kangaroo Care, a skin-to-skin, chest-to-chest method of caring for a baby, can positively benefit full-term infants and their mothers, with important implications for post-partum depression. The study provides evidence that the physiology of mothers and their full-term infants is influenced by Kangaroo...
