Microscopic evidence of malaria in the Medici era
Malaria was common in Renaissance Italy. The disease was known as "Febbre terzana" at the time as an onset of the fever occurred in intervals of two to three days. A research team led by Eurac Research has now microscopically detected the parasite Pl.....»»
Bonobo evidence suggests ancient origin of the "common enemy effect"
In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer to their own. Now an international team led by Kyoto University has shown that even our more peaceful cousins, bonobos—who have never been ob.....»»
The real price of the "zero-price effect": Study presents evidence from online classified real estate service
Researchers from Tel Aviv University found that there may be a cost to the zero-price effect: statistically identical homes that were published in free service ads on the Israeli "Yad2" online classified service received fewer clicks, sold more slowl.....»»
Mosquitoes use gut bacteria to fight the malaria they transmit—scientists are exploring how to use this
The months of September to May are an unfortunate season in South Africa: malaria season. The mosquito-borne disease is found in the north-eastern districts of KwaZulu-Natal, Mpumalanga and Limpopo provinces......»»
First spatial map of malaria infection in the liver opens new possibilities for more effective treatments
For the malaria parasite to reach the blood of its human host, it must first enter the liver, where only a small number of parasites differentiate and replicate for upward of seven days, making it a bottleneck in the parasite's lifecycle. This bottle.....»»
New forensics technique measures individual DNA shedding to aid criminal investigations
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect's individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes......»»
Ancient tree resin artifacts provide earliest-known evidence of humans dispersing through the Pacific
Exactly when and how humans dispersed into and through the Pacific remains an intensely debated topic. Previous studies have been hampered by imprecise chronometric dating, making the exact timing and movement of people into the Pacific difficult to.....»»
Morphable materials: Researchers coax nanoparticles to reconfigure themselves
A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, a.....»»
Scientists uncover exciton behavior in van der Waals magnets
A research group led by scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has uncovered details about the formation and behavior of mobile, microscopic, particle-like objects called "excitons" in a class of materials.....»»
Evidence stacks up for poisonous books containing toxic dyes
If you come across brightly colored, cloth-bound books from the Victorian era, you might want to handle them gently, or even steer clear altogether. Some of their attractive hues come from dyes that could pose a health risk to readers, collectors or.....»»
How some states help residents avoid costly debt during hard times
A new national study provides the best evidence to date that generous unemployment insurance benefits during the COVID-19 pandemic helped reduce reliance on high-cost credit use......»»
DNA study challenges thinking on ancestry of people in Japan
A genetic study led by researchers from RIKEN's Center for Integrative Medical Sciences has uncovered evidence that people in Japan descend from three ancestral groups......»»
Trojan horse method gives malaria parasites a taste of their own medicine
More than a quarter of Australians over the age of 50 take cholesterol-lowering drugs to prevent heart disease and strokes, but our bodies also need cholesterol to survive. Now, scientists from The Australian National University (ANU) say its role as.....»»
Earth"s oldest, tiniest creatures are poised to be climate change winners—and the repercussions could be huge
The world's oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as "prokaryotes," comprise 30% of life in the world's oceans......»»
Rocks collected on Mars hold key to water and perhaps life on the planet: Researchers urge bringing them back to Earth
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the red planet and even contain evidence for past life on Mars......»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
Opinion: Australian gambling industry is pulling out all the stops to prevent an ad ban, but the evidence is against it
With parliament sitting this week, the federal government is trying to finalize its proposed laws to limit gambling advertising......»»
New evidence from West Papua offers fresh clues about how and when humans first moved into the Pacific
In the deep human past, highly skilled seafarers made daring crossings from Asia to the Pacific Islands. It was a migration of global importance that shaped the distribution of our species—Homo sapiens—across the planet......»»
Starvation and adhesion drive formation of keratinocyte patterns in skin, research reveals
Fingerprints are one of the best-recognized examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors aff.....»»
Researchers find climate efficiency of farming has been leveling off
An international team of environmental scientists has found evidence that climate efficiency involving farming has been leveling off in recent years. For their study published in the Proceedings of the National Academy of Sciences, the group studied.....»»
Scientists find oceans of water on Mars. It"s just too deep to tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet's surface......»»
