Consciousness rests on the brain's ability to sustain rich dynamics of neural activity

A study found that consciousness is characterized by a complex configuration of interareal coordination, deviating from anatomical connections. In contrast, unconscious states are marked by positive patterns of interareal coherence dominated by brain region anatomy. The researchers suggest that transient brain signal coordination patte...

The unexpected creates reward when listening to music

Research at McGill University found that musically unexpected events elicit reward prediction errors in the nucleus accumbens, a brain region associated with musical pleasure. This discovery establishes music as a neurobiological reward capable of motivating learning and pleasurable listening experiences.

Why too much DNA repair can injure tissue

A recent study by MIT researchers found that overactive DNA-repair enzymes can lead to cell death and severe tissue damage in photoreceptor cells, a condition that may be linked to retinal blindness. The enzyme Aag glycosylase plays a key role in this process, promoting an inflammatory response that produces toxic intermediates.

Why does bribery work?

A Carnegie Mellon University study found that bribery works because people are motivated by greed, not the desire to reciprocate. When incentives are contingent on choices, bribes distort judgment more. However, when bribes don't influence outcomes, their effectiveness is reduced.

Simple and low-cost crack-healing of ceramic-based composites

Researchers at Osaka University demonstrated a world-first room-temperature crack-healing method for ceramic-based composites. The method uses electrochemical anodization to recover the strength of the composites to their original level, overcoming previous limitations with high-temperature heat treatment and resin adhesives.

Young children who express suicidal ideation understand death better than their peers

A recent study published in JAACAP found that young children who express suicidal thoughts have a better understanding of what it means to die. Children as young as four years old who expressed suicidal ideation demonstrated a solid understanding of death concepts, including the possibility of violent causes.

Gallbladder removal operation during pregnancy associated with adverse maternal outcomes

A study found that pregnant women who underwent gallbladder removal during pregnancy had longer hospital stays, increased readmissions, and higher rates of preterm delivery compared to those who delayed the operation until after childbirth. The researchers recommend waiting as long as possible for pregnant women with symptomatic gallst...

New diagnostic technique reveals a protein biomarker that accurately differentiates bladder cancer from benign inflammation

A new diagnostic technique using infrared imaging and proteomics has identified a protein biomarker called AHNAK2 that can accurately distinguish between bladder cancer and benign inflammation. The technique has been shown to have high sensitivity and specificity in differentiating between various stages of bladder cancer.

Walking simulation games signal a new literary genre

Research from the University of Kent reveals that walking simulations are blurring art forms, creating a new genre with stories akin to reading a book. Games like Dear Esther engage players more than traditional video games, making it a fantastic way to tell a story.

Some primary care doctors not prepared to help with cancer treatment decisions

A new study found that up to one-third of primary care physicians discussed breast cancer treatment options with patients. However, many reported notable gaps in their knowledge of these topics. The research highlights the importance of educating primary care providers on cancer treatment options and supporting them in making informed ...

Ice volume calculated anew

A recent study calculates the ice thickness distribution and volume of over 215,000 glaciers worldwide, revealing that the combined ice volume currently stands at around 158,000 cubic kilometres. The largest glacier ice masses, primarily in the Arctic, account for nearly half of the global glacier ice volume.

How to pay top executives if you want them to be innovative

A recent study by Bocconi University and University of Bath found that high pay dispersion in variable pay is associated with increased innovation, whereas low pay dispersion in fixed pay hinders it. The researchers measured the innovation output of US firms from 1992 to 2006 using patent data and citations received.

Teaching self-driving cars to predict pedestrian movement

University of Michigan researchers develop a novel approach to teaching self-driving cars to recognize and predict pedestrian movements. They achieve this by analyzing humans' gait, body symmetry, and foot placement using cameras, LiDAR, and GPS data. The system can predict poses and future locations for one or several pedestrians up t...
