Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations

A team of scientists from Waseda University and Tokyo Institute of Technology have successfully demonstrated large-angle photothermally resonated high-speed bending induced by pulsed UV irradiation. They used 2,4-dinitroanisole β-phase crystals to achieve a fast natural vibration at 390 Hz with a large photothermal bending angle.

Even worms get the munchies

A study by University of Oregon researchers found that worms become even more attracted to high-quality food when exposed to anandamide, a molecule in marijuana. This phenomenon is similar to human 'hedonic feeding' behavior, where people crave certain foods after consuming cannabis.

How bee-friendly is the forest?

Researchers found that honeybees use forests less than expected, with colonies traveling long distances to find food due to limited tree species diversity. A more diverse forest with insect-pollinated trees and shrubs can provide a balanced food supply throughout the season.

New lung immuno-oncology therapeutic strategy identified

Researchers at Mount Sinai have discovered a new therapeutic approach to treating non-small-cell lung cancer by inhibiting immune system molecule TREM2 and enhancing natural killer cells. The strategy, which involves blocking TREM2 activity using an antibody, has been shown to significantly reduce lung tumor growth in mice.

Ultra-miniaturized non-classical light sources for quantum devices

The researchers developed a method to create ultracompact photonic crystal cavities that can generate entangled photons. The discovery is crucial for the development of quantum computing and sensing applications. By controlling the cavity's properties, they can efficiently convert pump power into coherent light.

African penguins: climate refugees from a distant past?

The study reveals that the African penguin's geographical range has shrunk significantly over the past 22,000 years due to rising sea levels, leaving only a few small islands as suitable nesting habitats. This decline has been exacerbated by human pressures such as climate change, habitat destruction, and competition for food.

‘Antibiotic culture’ permeates US hospital ICUs

A study by Florida Atlantic University researchers found a significant 'antibiotic culture' in US hospital ICUs, with up to 70% of patients receiving unnecessary antibiotics. The preference for antibiotics is driven by urgency, hierarchy, and uncertainty, leading to increased use despite antimicrobial stewardship guidelines.

A myth no more: Cranberry products can prevent urinary tract infections for women

A global study published in Cochrane Reviews found that consuming cranberry products reduces the risk of repeat symptomatic UTIs in women by more than a quarter. The review also showed benefits for children and people susceptible to UTIs following medical interventions, with minimal side effects reported.

Dr. Dae Kim to be honored with the 2023 Thomas and Catherine Yoshikawa Outstanding Scientific Achievement in Clinical Investigation Award at #AGS23

Dae Kim, MD, MPH, ScD, will receive the 2023 Thomas and Catherine Yoshikawa Outstanding Scientific Achievement in Clinical Investigation Award for his work on frailty research. His contributions have significantly impacted clinical care, particularly in primary care groups using the claims-based frailty index to risk stratify patients.

Study shows human tendency to help others is universal

A new study found that people of diverse cultures, including those from England, Italy, Poland, and Russia, tend to help others in everyday life. The researchers analyzed video recordings of social interactions in 350 individuals from eight languages and cultures and found that the human tendency to help others is a universal principle.

THE LANCET: Minimum unit pricing for alcohol associated with a 13% decrease in deaths from alcohol consumption in Scotland, study suggests

A new study published in The Lancet finds that minimum unit pricing for alcohol is associated with a 13% decrease in deaths from alcohol consumption in Scotland. The policy has also led to significant reductions in alcohol-specific hospitalisations and long-term conditions, such as alcoholic liver disease and alcohol dependence syndrome.
