Quantum holograms as atomic scale memory keepsake

Researchers from St. Petersburg State University developed a theoretical model for quantum memory in light, adapting classical hologram concepts to a quantum system. They demonstrated the possibility of retrieving specific portions of stored quantized light signals with precise control over space and time.

Flu vaccine may hold key to preventing heart disease

A new study reveals how flu vaccines prevent heart attacks by stimulating the immune system to produce antibodies that protect the heart. The research identifies a protein called BKB2R as the key mechanism behind this protective effect, and suggests it could be harnessed to develop a vaccine against heart disease.

Less-numerate investors swayed by corporate report presentation effects

New research finds that less-numerate investors are more susceptible to style and presentation effects of social responsibility reports, potentially leading to unintended judgments. Companies can design CSR reports with a uniform approach to project strategy, aligning text and graphics to convey information effectively.

Kung fu stegosaur

Paleontologists uncover fatal stab wound in allosaur's pubis bone, suggesting stegosaurs wielded their tails as deadly weapons. The discovery challenges conventional views of stegosaurs as lumbering plant-eaters, highlighting their impressive dexterity and fighting skills.

Reading a biological clock in the dark

A new study published in Cell reveals that our biological clocks work in tandem with the populations of bacteria residing in our intestines. The findings show that mice and humans with disrupted daily wake-sleep patterns exhibit changes in gut bacteria composition and function, increasing their risk for obesity and glucose intolerance.

Towards controlled dislocations

A group of scientists from the US used atomic-resolution Z-contrast imaging and X-ray spectroscopy to analyze two types of dislocations in CdTe, a binary II-VI semiconductor. The study could lead to improved conversion efficiency in CdTe solar cells and advance understanding of crystal structure defects.

Siblings of children with autism can show signs at 18 months

A new study by Yale School of Medicine researchers has found that about 20% of younger siblings of children with Autism Spectrum Disorder (ASD) will develop the condition by age 3. The study identified specific social-communicative behaviors at 18 months that distinguish infants with ASD from their peers.

Interleukin-27: Can a cytokine with both pro & anti-inflammatory activity make a good drug target?

A new Review article explores the potential to target IL-27-activated mechanisms in diseases such as multiple sclerosis and Crohn's disease. The cytokine's dual anti-inflammatory and proinflammatory activities suggest it could be a significant determinant of inflammatory responses.

Scientists create possible precursor to life

Researchers from the University of Southern Denmark discover information strings with peculiar properties that can replicate quickly and efficiently, leading to a self-organizing autocatalytic network. This mechanism has potential value for developing technology based on living processes, such as self-healing devices.

Physicists build reversible laser tractor beam

Researchers created a reversible laser tractor beam that can repel and attract particles, moving them up to 20 centimeters with a single laser beam. The technique uses energy heating and polarization control to manipulate particles, offering new possibilities for atmospheric pollution control and tiny particle retrieval.

Why sign rights treaties?

A new study finds that autocratic leaders who sign human-rights treaties do so for domestic political maneuvering rather than economic gains. The researchers analyzed four core treaties and found no evidence of tangible material rewards for ratification.
