You might think that prey would invariably flee in terror from a predator. But what if an animal was apathetic in the face of danger?
A new study in Frontiers in Ecology and Evolution investigates why some moths are more relaxed fliers in the face of bat attacks. The research reveals that less appetizing moths are more nonchalant when attacked by bats, whereas more palatable moths tend to employ evasive maneuvers.
Black teenagers experience daily racial discrimination, most frequently online, which can lead to negative mental health effects, according to a Rutgers researcher.
The study, published in the Journal of Applied Developmental Psychology, examined how often black teens experience racial discrimination each day - either personally or vicariously and online or offline.
Some of the most well-known literary works were left unfinished when the authors died, masterpieces like The Trial by Franz Kafka, Maria or The Wrongs of Woman by Mary Wollstonecraft and The Canterbury Tales by Geoffrey Chaucer.
By tracking the motions of cold atom clouds, astronomers can learn much about the physical processes which play out in the depths of space. To make these measurements, researchers currently use instruments named 'cold atom inertial sensors' which, so far, have largely been operated inside the lab. In new work published in EPJ D, a team of physicists at Muquans and LNE-SYRTE (the French national metrology laboratory for time, frequency and gravimetry) present an innovative prototype for a new industrial laser system.
The fragmentation of natural habitats by fences and human settlements is threatening the survival of the white rhinoceros. It prevents dispersal from the family group and leads to mating among close relatives. Additionally female rhinoceros favour individual males for mating over others and sire several offspring with the same partner over consecutive breeding periods. These factors lead to a high degree of inbreeding. The results come from the largest scientific study to date on the sexual preferences of white rhinos, published in the journal "Evolutionary Applications".
WASHINGTON, Dec. 16, 2019 -- Are bananas actually that slippery? Could spinach give you superhuman strength? And what the heck is Toon Acid? This week, watch some cartoons alongside our writer and host, Sam Jones, and learn whether their chemistry checks out: https://youtu.be/AiEgZOrRJg4.
SAN ANTONIO -- Mayo Clinic researchers will present findings at the San Antonio Breast Cancer Symposium Dec. 10-14 in San Antonio.
New Mayo Clinic studies to be presented include:
"Women at Elevated Risk of Developing Breast Cancer May Benefit From Taking Anti-inflammatory Drugs"
Embargoed until Friday, Dec. 13, at 6 p.m. EST
Research from Mayo Clinic investigators suggest that some women with an elevated risk of developing breast cancer may benefit from taking anti-inflammatory medications.
The matrix shell of the HIV-1 virus may have a different shape than previously thought, and a newly proposed model has significant implications for understanding how the virus functions, according to a new study by University of Alberta scientists.
The research suggests that the HIV-1 virus is housed within a spherical matrix shell. When it infects a healthy cell, the shell fuses to the outside of the target cell and then releases the viral capsid inside where it attacks the cell.
A novel technological approach developed by researchers at Baylor College of Medicine expands from two to six the number of molecular pathways that can be studied simultaneously in a cell sample with the dual luciferase assay, a type of testing method commonly used across biomedical fields.
Described as "living rocks", giant land tortoises are lumbering beasts with a reputation for being sluggish in both speed and brainpower. But new research carried out by scientists from the Okinawa Institute of Science and Technology (OIST) suggests we have greatly underestimated the intelligence of these creatures, who can not only be trained but also have amazing powers of long-term recall.
A new study found that people who presented to California emergency departments with deliberate self-harm had a suicide rate in the year after their visit 56.8 times higher than those of demographically similar Californians. People who presented with suicidal ideation had suicide rates 31.4 times higher than those of demographically similar Californians in the year after discharge. The findings, published in JAMA Network Open, reinforce the importance of universal screening for suicide risk in emergency departments and the need for follow-up care.
PROVIDENCE, R.I. [Brown University] -- A team of Brown University researchers has used a brain-computer interface to reconstruct English words from neural signals recorded in the brains of nonhuman primates. The research, published in the journal Nature Communications Biology, could be a step toward developing brain implants that may help people with hearing loss, the researchers say.
The recovery of pine marten in Ireland and Britain is reversing native red squirrel replacement by invasive grey squirrels, according to new research presented at the British Ecological Society's annual meeting in Belfast today.
Researchers at Queens University, Belfast and National Museums Northern Ireland have found red squirrels are responding positively to the increased presence of pine martens across Northern Ireland. So, where pine martens occur, it increases the chances of red squirrels occurring, simultaneously reducing the likelihood of grey squirrels being present.
Lancaster University researchers have shed light on how the parasite which causes sleeping sickness multiples inside its host.
Human African Trypanosomiasis or sleeping sickness, only occurs in Sub-Saharan Africa where an estimated 60 million people in 36 countries are at risk.
WASHINGTON--While older adults with hypothyroidism face an elevated risk of death, individuals with subclinical hypothyroidism, a milder form of underactive thyroid, did not face the same risk, according to new research published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
