Study preserves memory in mice, offering promising new basis for active immunization against Alzheimer’s disease
During experiments in animal models, researchers at the University of Kansas have discovered a possible new approach to immunization against Alzheimer’s disease (AD). Their method uses a recombinant methionine (Met)-rich protein derived from corn that was then oxidized in vitro to produce the antigen: methionine sulfoxide (MetO)-rich protein. This antigen, when injected to the body, […]
New study reveals brain circuit responsible for cocaine withdrawal-induced anxiety and relapse-related behavior
New research from the University of California, Irvine, finds that drug withdrawal-induced anxiety and reinstatement of drug seeking behaviors are controlled by a single pathway in the brain and centered around dopamine cells. The study, “An extended amygdala-midbrain circuit controlling cocaine withdrawal-induced anxiety and reinstatement,” was published today in Cell Reports. Addiction occurs in phases: […]
How can mental health professionals open their minds to psychosis?
Effective clinical care for patients with psychosis means understanding the “lived experience” of their delusions, say researchers at the Universities of Birmingham, York and Melbourne. By understanding the intricacies of feelings, attitudes, and experiences that are interlinked with delusions, clinicians will be better able to build trust and genuine engagement with patients. In a new […]
NASA’s Mars Helicopter scouts ridgeline for Perseverance science team
NASA’s Ingenuity Mars Helicopter recently surveyed an intriguing ridgeline near the ancient river delta in Jezero Crater. The images—captured on April 23, during the tiny helicopter’s 27th flight—were taken at the request of the Perseverance Mars rover science team, which wanted a closer look at the sloping outcrop. “Ingenuity not only provides imagery from an […]
In poplars, two plant hormones boost each other in defense against pathogenic fungi
In contrast to previous assumptions, the defense hormones salicylic acid and jasmonic acid do not always suppress each other in regulating plant chemical defenses against pests and pathogens. In trees, the interplay of both hormones can actually increase plant resistance. This is the conclusion researchers from the Max Planck Institute for Chemical Ecology draw in […]
Studying wealth inequality in animals can reveal clues about how their societies evolved
Wealth inequality is a research topic typically reserved for humans. Now, research from the Max Planck Institute of Animal Behavior and the University of Nebraska-Lincoln suggests that studying wealth inequality in animals can help shed light on social evolution. Adapting approaches from the study of wealth inequality in humans, the researchers show how wealth—in the […]
Experiments measure freezing point of extraterrestrial oceans to aid search for life
Researchers from the University of Washington and the University of California, Berkeley have conducted experiments that measured the physical limits for the existence of liquid water in icy extraterrestrial worlds. This blend of geoscience and engineering was done to aid in the search for extraterrestrial life and the upcoming robotic exploration of oceans on moons […]
Most Vegetarian Children Are Just As Well Nourished As Meat Eaters
Children raised on vegetarian diets tend to receive similar levels of key nutrients to those who eat meat, according to a new study in the journal Pediatrics. However, the researchers found that veggie kids have a slightly higher risk of being underweight, highlighting the need for careful consideration and planning when it comes to feeding […]
Cannabis Smoking Linked To Heart Attacks, But Soy Compound Reverses Risk
Regular stoners may have a higher risk of developing heart disease or having a heart attack, according to a new study in the journal Cell. The researchers found that smoking a joint triggers a rapid increase in pro-inflammatory compounds that can harm blood vessels – but a molecule from soy may help to alleviate this […]
Is Intermittent Fasting Good For Dogs? Massive Study Weighs In On Possible Benefits
The voracious appetites of dogs seemingly know no bounds, so as guardians it’s down to humans to work out the best type and volume of food to feed domestic canines. Recent research claimed there were benefits to a vegan diet, and now a new paper has suggested that just one meal a day could be […]
