Selective memory

Researchers developed a new cache-management scheme that improves the data rate of in-package DRAM caches, reducing metadata transfer and increasing bandwidth. The 'Banshee' system adds three bits of data to each entry, enabling efficient storage and retrieval of frequently used data.

Introduction of a novel system for in vitro analyses of zebrafish oligodendrocyte progenitor cells

Researchers have developed a novel in vitro platform to analyze zebrafish oligodendrocyte progenitor cells, which could lead to improved spinal cord repair in humans. The system allows for efficient and controlled analysis of these cells, enabling the study of their differentiation into mature oligodendrocytes.

Rhythm of memory

A study by Prof. Dr. Marlene Bartos and her team found that inhibiting circuits in the hippocampus create high-frequency brainwaves that support parallel processing and storage of information, a key mechanism for laying initial traces of memory.

Activation of immune T cells leads to behavioral changes

Scientists have discovered that T cell activation leads to a depletion of amino acids in the blood, which in turn affects neurotransmitters serotonin and dopamine, causing anxiety and fear responses. In mice without PD-1 receptor, they found behavioral changes dominated by anxiety and exacerbated fear responses.

Crops evolving 10 millennia before experts thought

Research reveals that humans systemically affected crop evolution up to 30,000 years ago, triggering domestication of rice, wheat, and barley. This discovery proves the existence of dense populations and challenges previous understanding of agriculture's origins.

How hospitals respond when it's uncertain if the newborn is a boy or a girl

A new study found substantial variability across US medical centers in diagnosing and treating disorders of sex development (DSD), with some institutions lacking specialist teams. Families often face difficult decisions about irreversible procedures, highlighting the need for improved guidelines and collaboration among providers.

Novel therapies for multidrug-resistant bacteria

Researchers have developed novel antimicrobial compounds that can treat multidrug-resistant bacteria, enhancing the effectiveness of traditional antibiotics. The combination of colistin and a manganese tricarbonyl complex showed significant antibacterial activity in killing multidrug-resistant bacteria.

Solution to mysterious behavior of supercooled water

The study reveals that anomalous molecular motions in supercooled water lead to the breakdown of Stokes-Einstein behavior, with regions forming hydrogen bonds heterogeneously. The findings provide insights into the physical implications of this anomaly, which could help explain dynamic behaviors in glassy materials.

IUPUI receives NSF grant to enhance geosciences education, expand community engagement

IUPUI has received a $428,000 NSF grant to develop a novel educational program that enhances geosciences education and inspires students to address community problems. The program will engage undergraduates from underrepresented groups and provide opportunities for them to explore environmental justice through a themed learning community.

Better sleep, less fear

A study by Itamar Lerner and colleagues found that higher quality sleep patterns are associated with reduced activity in brain regions involved in fear learning. The researchers suggest that baseline sleep quality may be a useful predictor of susceptibility to post-traumatic stress disorder (PTSD).

NUS researchers discover pathway by which blood cells release a potent signalling factor

Researchers at the National University of Singapore have discovered a critical molecular target for sphingosine-1-phosphate production, paving the way for regulating its signalling in circulation. Low levels of S1P have been linked to various immune and vascular diseases, including multiple sclerosis and cardiovascular complications.
