Research found that subordinate fish go on a diet to avoid provoking fights, maintaining social hierarchy in coral reef groups. This discovery challenges traditional views on dominant individuals retaining their position through size and intimidation.
A new study has found that men are more likely to crave alcohol when they feel negative emotions, such as sadness and anxiety. Women tend to ruminate on these feelings, while men may distract themselves by using alcohol as a coping mechanism.
A randomized controlled trial evaluated the effectiveness of naltrexone alone and in combination with sertraline among Alaskans living in rural settings. The study found that naltrexone significantly improved abstinence rates compared to placebo, with 35% of participants remaining abstinent for the entire 16-week treatment.
A recent study found that binge drinkers, even when legally intoxicated, believe they have adequate driving abilities. However, their performance on a simulated driving task was poor. The researchers propose that lack of internal sedation cue and variable drinking habits may be responsible for this disconnect.
Researchers at Melbourne's Walter and Eliza Hall Institute have discovered a key step in the 'puncture' mechanism of cell death, which drives apoptosis. The discovery has important implications for the development of drugs that can regulate cell death, with potential applications in cancer and degenerative disease treatments.
A mutated gene has been discovered as the key behind epilepsy and mental retardation specific to women, thanks to new research at the University of Adelaide. The study found that women carry both a 'good' and 'bad' gene, while men only carry the bad gene, leading to the condition affecting only females.
Researchers at Beth Israel Deaconess Medical Center have identified a new gene trigger for preeclampsia, a dangerous pregnancy disorder affecting 5% of pregnancies worldwide. A steroid molecule, 2-ME, may serve as both a diagnostic marker and therapeutic supplement for the treatment of preeclampsia.
A new study reveals that female concave-eared torrent frogs emit high-pitched chirps spanning audible and ultrasonic frequencies to signal their interest. Males respond instantaneously, with impressive accuracy in localizing the sound, a feat shared only by elephants, humans, barn owls, and dolphins.
Researchers at Columbia University Irving Medical Center have discovered a previously unknown alteration in microRNA production linked to schizophrenia. By modeling mice with the same chromosome 22q11.2 deletion as humans with schizophrenia, they found that abnormalities in microRNAs can lead to synaptic and behavioral deficits.
A study funded by the Economic and Social Research Council found that British adult children help their elderly parents according to their needs, rather than past behavior. Parents with health problems are 75% more likely to receive help from their children.
Researchers have identified a key human aging gene in fruit flies, revealing its role in DNA instability and genome rearrangement. This breakthrough enables the use of fruit flies as a powerful model system to study the effects of aging on human health.
Researchers have discovered a timing mechanism in the brain of fruit fly larvae that controls their avoidance of food and could lead to new pain relief methods. This mechanism has counterparts in mammalian models involved in psychological processes such as food response, anxiety suppression, and pain perception.
