How a Japanese far-right hate group helped popularize anti-Korean sentiment
Studies show that anti-Korean sentiment in Japan has grown steadily in the past decade, despite the growing acceptance of more visibly "foreign" Southeast Asian migrants in Japan. A University of Notre Dame researcher conducted two years of ethnographic fieldwork in a historic Korean ghetto in Osaka, Japan, to shed light on the legacy of discrimination that third- and fourth-generation Korean...

Robot mimics the powerful punch of the mantis shrimp
- ScienceDaily
- 21/8/25 21:37
Mantis shrimp pack the strongest punch of any creature in the animal kingdom. How mantis shrimp produce these deadly, ultra-fast movements has long fascinated biologists. Now, an interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these...

LED streetlights contribute to insect population declines: study
Streetlights—particularly those that use white light-emitting diodes (LEDs)—not only disrupt insect behavior but are also a culprit behind their declining numbers, a new study carried out in southern England showed Wednesday.
Underlying instincts: An appetite for survival
Microscopic roundworms may hold the key to understanding what is happening in the brain when the instinct of an animal changes in order to survive. In a newly published paper in the journal Current Biology, University of Rochester Medical Center researchers found that a signaling system in the brain changes to redirect the behavior of an animal when their survival is at risk because there is not...
The boiling crisis and how to avoid it
It's rare for a pre-teen to become enamored with thermodynamics, but those consumed by such a passion may consider themselves lucky to end up at a place like MIT. Madhumitha Ravichandran certainly does. A Ph.D. student in Nuclear Science and Engineering (NSE), Ravichandran first encountered the laws of thermodynamics as a middle school student in Chennai, India. "They made complete sense to me,"...

Men and women of Roman Herculaneum had different diets, new research shows
- ScienceDaily
- 21/8/25 20:31
Archaeologists examining the Herculaneum skeletal remains of the victims of Vesuvius say they have helped shed new light on the eating habits of ancient Romans -- with food differentiated along gender lines and revealing women ate more animal products and locally grown fruit and vegetables while the men dined on more expensive fish.
‘Nanojars’ capture dissolved carbon dioxide, toxic ions from water
- ScienceDaily
- 21/8/25 20:31
Carbon dioxide from the atmosphere dissolves in waterways, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxide later. Now, researchers have developed tiny 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so...

- ScienceDaily
- 21/8/25 20:30
A beam of light can only be seen when it hits matter particles and is scattered or reflected by them. In a vacuum, however, it is invisible. Physicists have now developed a method that allows laser beams to be visualized even under these conditions. The method makes it easier to perform the ultra-precise laser alignment required to manipulate individual atoms.

Protecting gardens and crops from insects using the ‘smell of fear’
- ScienceDaily
- 21/8/25 20:29
For home gardeners and farmers, herbivorous insects present a major threat. The predator insects that feed on these bugs emit odors that pests can sense, which changes the pests' behavior and physiology to avoid being eaten. With bugs becoming more resistant to traditional pesticides, researchers now report they have bottled the 'smell of fear' produced by predators to repel and disrupt insects...
