Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.
When small hierarchical groups bond, neural activity between leaders and followers aligns, promoting quicker and more frequent communication, according to a new study.
Men and women with lower income or education levels are more likely to develop medical conditions related to alcohol abuse compared to similar individuals with a higher socioeconomic status, according to a new study.
Claims that climate change is natural are inconsistent with new oceanic temperature trends.
A new study has shown that food-seeking cells exist in a part of a mouse's brain usually associated with panic -- but not with feeding. Activating a selective cluster of these cells kicked mice into 'hot pursuit' of live and non-prey food, and showed a craving for fatty foods intense enough that the mice endured foot shocks to get them, something full mice normally would not do. If true in humans, who also carry these cells, the findings could help address the circuit that can circumvent the normal hunger pressures of 'how, what and when to eat.'
A study of 130 Global South nations has found that their greenhouse gas emissions were linked with IMF lending policies. The constraints of IMF's structural loans imposed coercive lending conditions that prompted borrowers to focus on increasing their exports, indirectly raising their greenhouse gas emissions through greater agricultural or manufacturing activities. GHG emissions increased within several years of countries' first structural loan, and increased almost immediately with subsequent loans, regardless of the lending conditions, the study found.
A new study shows the keto diet prevents early memory decline in mice. A molecule in the diet plays a key role in slowing Alzheimer's disease.
Scientists advocate for change to promote standardized practices in the field -- a practice that has been missing from the science.
A new study suggests anyone looking to shake off the winter blues by planning the perfect getaway should turn to ChatGPT.
Astronauts have been able to track their muscle health in spaceflight for the first time using a handheld device, revealing which muscles are most at risk of weakening in low gravity conditions. Researchers monitored the muscle health of twelve astronauts before, during and after a stay on the International Space Station.
Treating anxiety and depression significantly reduced hospital readmission and emergency room visits in people with heart disease.This may be the first study to show that treating anxiety and depression with medication or psychotherapy has a significant impact on heart disease outcomes.
A mobile app that uses artificial intelligence, AI, to analyze images of suspected skin lesions can diagnose melanoma with very high precision, according to a new study.
Scientists found that farmed salmon production leads to an overall loss of essential dietary nutrients. They say that eating more wild 'feed' species directly could benefit our health while reducing aquaculture demand for finite marine resources.
Researchers have called for a more considered approach when embedding ethical principles in the development and governance of AI for children.
Biologists have published a chromosomally assembled reference genome for the European brown hare. The genome consists of 2.9 billion base pairs, which form 23 autosomal chromosomes, and X and Y sex chromosomes. The timing of the genome release is very appropriate as the brown hare also represents the original Easter Bunny familiar from European folklore.
A study of nearly 95,000 Washington state residents found that people living outside of urban areas as well as Native American and Hispanic people face longer travel distances to be seen by neurologists. The researchers said these disparities could be contributing to delayed diagnoses, which can result in higher costs of care, reduced chances of preserving cognitive function and lower quality of life for dementia patients.
Researchers have uncovered intriguing details about the origins and spread of the bottle gourd, one of the oldest domesticated crops. Their work unveils the genetic diversification and population history of this hard-shelled plant that was used to make bottles, instruments, and containers for over 10,000 years by ancient civilizations.
In a new study, researchers found that a carefully worded, short questionnaire successfully identified people who were most likely to develop chronic pain. These patients were then steered to a more detailed risk stratification and holistic services that led to better outcomes.
A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19.
Using advanced methodology, scientists have been able to reveal at the cellular level how lesions in multiple sclerosis develop.
