Dolphins’ “Smile” Reveals Playful Intentions

Bottlenose dolphins use an "open mouth" expression, similar to a smile, during playful interactions with other dolphins. This expression is a signal of fun and playfulness, preventing misunderstandings as aggression.

New Therapy Improves Depression in Fathers

A new study shows that a group parenting intervention significantly reduces male postpartum depression (PPD) in Pakistani fathers, with over 70% of participants experiencing full remission of symptoms. The program, "Learning Through Play Plus Dads," also improved child development and strengthened relationships within families.

Cannabis Pill Reduces Agitation in Alzheimer’s Patients by 30%

A new study reveals that dronabinol, a synthetic form of THC, can reduce agitation in Alzheimer’s patients by 30%. Unlike current medications, dronabinol showed fewer side effects, such as delirium or seizures, making it a safer alternative.

Neurology News Articles

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Personalized Immune Therapy Offers Hope for MS Patients

A new study explores the use of tolerogenic dendritic cells (tolDCs) to restore immune balance in multiple sclerosis (MS) patients without compromising their immune system. The research reveals that MS patients’ immune cells have a pro-inflammatory signature, even after being modified for therapy.

Time of Day Affects Key Biomarkers for Alzheimer’s Diagnosis

New research shows that the time of day when blood samples are taken significantly impacts the levels of Alzheimer's biomarkers, including p-tau217, which is crucial for early diagnosis. Biomarker levels were found to be lowest in the morning and highest in the evening, indicating that timing could affect dementia diagnosis and monitoring.

MRI-Guided Radiation Shows Promise for Glioblastoma

MRI-guided radiation, or MRI-linac, can monitor glioblastoma tumor changes in real-time during radiation therapy. Researchers found that daily MRI scans accurately matched tumor changes detected by standard imaging 74% of the time and predicted growth earlier in 26% of cases.

AI News Articles

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

ChatGPT Matches Radiologists in Brain Tumor Diagnosis Accuracy

Researchers compared the diagnostic accuracy of GPT-4 based ChatGPT and radiologists using 150 brain tumor MRI reports. ChatGPT achieved 73% accuracy, slightly outperforming neuroradiologists (72%) and general radiologists (68%).

AI Reveals How Infants Learn to Interact with Environment

Researchers used artificial intelligence (AI) to study how infants transition from random movements to purposeful actions. By tracking infant movements in a baby-mobile experiment, AI models like 2D-CapsNet accurately classified these movements and identified significant changes in foot movements as infants learned to interact with their environment.

AI Detects Depression Through Eyes and Facial Cues

Researchers are developing AI-driven smartphone applications to detect signs of depression non-invasively. One system, PupilSense, monitors pupillary reflexes to identify potential depressive episodes with 76% accuracy. Another tool, FacePsy, analyzes facial expressions and head movements to detect subtle mood shifts, with unexpected findings like increased smiling potentially linked to depression. These tools offer a privacy-protective, accessible way to identify depression early, leveraging everyday smartphone use.

Psychology News Articles

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Humans Slow Speech to Help Dogs Understand

A new study reveals that humans naturally slow their speech when talking to dogs, which helps dogs better understand commands. Researchers analyzed speech rates and brain responses in 30 dogs and 27 humans across five languages, finding that humans speak at around three syllables per second to their pets, compared to four syllables when talking to other humans.

Reduced Brain Response to Visual Cues Linked to Psychosis in Parkinson’s

People with Parkinson's disease (PD) who experience visual hallucinations have reduced brain responses to unexpected visual changes, a marker known as visual mismatch negativity (vMMN). Using EEG, researchers compared brain activity in PD patients with and without hallucinations and discovered that those with hallucinations showed weaker vMMN signals.

Wildlife Tagging Alters Behavior for Days

A new study reveals that the stress of capturing and tagging wildlife affects their behavior for several days, altering their activity levels and movement patterns. By tracking 1,585 individuals from 42 species fitted with GPS collars, researchers found that predators tended to reduce their activity while herbivores often increased movement post-release.

Gut Microbiome and Aspirin May Reverse Hormonal Issues

Researchers found that mutations in the Sox3 gene cause hypopituitarism, a condition where the pituitary gland produces insufficient hormones, leading to growth issues and infertility. In a study on mice, they discovered that Sox3 mutations affect brain cells called NG2 glia, which are essential for hormone production.

Cadmium Exposure Linked to Memory Issues

A recent study explored the link between cadmium exposure and cognitive decline, finding that higher cadmium levels may be associated with thinking and memory problems in white people. The study followed 2,172 people over 10 years, with results showing no association overall but revealing a possible link when analyzing Black and white participants separately.

Study Supports Quantum Basis of Consciousness in the Brain

A new study suggests that consciousness may be rooted in quantum processes, as researchers found that a drug binding to microtubules delayed unconsciousness in rats under anesthesia. This discovery supports the idea that anesthesia acts on microtubules, potentially lending weight to the quantum theory of consciousness. The research challenges classical models of brain activity, suggesting that consciousness could be a collective quantum vibration within neurons. These findings could reshape our understanding of consciousness, with implications for anesthesia, brain disorders, and consciousness in non-human animals.

Manipulating Brain Waves During Sleep With Sound

Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions. The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients' lives.

Anti-inflammatory Drug Boosts Motivation in Depression

A new study reveals that infliximab, an anti-inflammatory drug, can improve motivation in patients with depression and high inflammation. Researchers found that patients receiving infliximab showed greater effort in reward-based tasks, correlating with changes in brain activity in key motivation regions.
