Japan’s “soft” but not ineffective approach to public health during the COVID-19 pandemic

Researchers from Osaka University found that Japan's state of emergency declarations led to increased hygienic behaviors and risk perception, which persisted even after the policy was lifted. However, older people became less fearful of COVID-19 and were less likely to wear masks.

SNU researchers apply the principles of mantis shrimp and fleas to create soft robots with powerful movements

Researchers created a 'Hyperelastic Torque Reversal Mechanism' that enables fast and powerful movements in soft robots made from rubber-like materials. The mechanism leverages the characteristics of soft hyperelastic materials to rapidly stiffen as they compress, allowing for rapid and efficient movement.

A less ‘clumpy,’ more complex universe?

Combining data from two major surveys of the universe's evolutionary history reveals a small discrepancy between expected clumpiness and observed matter distribution. This deviation could suggest unaccounted-for physics influencing cosmic structure formation, such as dark energy.

In HER2+ colorectal cancer, anti-HER2 therapy may be less toxic alternative

A phase 2 clinical trial found that a combination of two HER2 inhibitors was more effective and better tolerated than standard EGFR inhibitor-based therapy for patients with HER2-positive metastatic colorectal cancer. The study showed that the level of HER2 amplification in tumors played a key role in determining treatment outcomes.

Scientists discover a genetic lifeline for the endangered shortfin mako shark

A new study reveals that despite decades of overfishing, Atlantic shortfin mako sharks still exhibit a relatively high level of genetic diversity. This means they have the potential to adapt to environmental changes and survive as our climate shifts. The research provides urgency to halt overfishing and protect this species.

Chiropractic associated with reduction in opioid-related adverse drug events: new study

A new study found that adults with newly diagnosed sciatica who received chiropractic spinal manipulation experienced significantly lower rates of opioid-related adverse drug events compared to those receiving usual medical care. The study highlights the potential benefits of non-pharmacological approaches in managing pain.

Turning farm waste into sustainable roads

Researchers led by Xianming Shi are exploring the use of agricultural waste to build roadways, aiming to reduce carbon emissions from asphalt production. Biochar, a CO2-negative material produced through pyrolysis, can sequester carbon in asphalt pavement and potentially extend its lifespan.

Young people support the idea of a smokefree generation, according to a new study

A new study finds that young people in England broadly welcome the smokefree generation policy, seeing it as a chance to free their generation from harmful addiction. The study, led by the University of Nottingham, involved focus groups with participants aged between 12 and 21, who expressed support for the policy's implementation.

How group size affects cooperation: Insights from brain science

A recent study by Rei Akaishi at RIKEN CBS found that larger groups can actually promote greater cooperation. Participants in the 'prisoner's dilemma' game cooperated more frequently as group size grew, with brain scans showing increased activity in regions involved in prosocial behavior and memory processing. This challenges conventio...
