Corporate social responsibility acts as an insurance policy when companies cut jobs and benefits during the times of crisis

Research found that companies with strong corporate social responsibility are more likely to be forgiven by employees for breaches, as they are seen as conscientious and socially responsible. This can help mitigate the negative consequences of psychological contract breach during times of crisis.

New sensor sniffs out look-alike molecules in the air

Researchers developed a new type of gas sensor that can identify different types of air components by recognizing tiny structural differences in common volatile compounds. The sensor, which uses custom-built sugar-based receptors, shows promise for future non-invasive medical diagnostics, environmental monitoring, and quality control.

Caribbean rainfall driven by shifting long-term patterns in the Atlantic high-pressure system, study finds

A new study challenges long-standing climate science paradigms, finding that the Caribbean often experiences drought during intensified summer insolation due to the strengthening and westward expansion of the North Atlantic Subtropical High. This high-pressure system suppresses convection and reduces rainfall across the region.

What is that dog taking? CBD supplements could make dogs less aggressive over time, study finds

A recent study found that dogs given CBD supplements show below-average levels of aggression over time, with the most aggressive changes observed in male dogs. The study, which used data from almost 50,000 dog owners, also found a link between CBD use and health conditions such as dementia and osteoarthritis.

Reducing human effort in rating software

Researchers found that Large Language Models (LLMs) can replace human effort in low-context, deductive labelling tasks with high accuracy. However, for high-context tasks, LLMs are unreliable due to a lack of deep situational awareness. The study suggests using LLMs for selective samples and providing them with 'few-shot' prompts to in...

Collaborating for improved governance

The study explores how to nurture and manage collaborative networks to improve community-level outcomes, particularly in food systems, regional economic development, and renewable energy innovation. It focuses on the characteristics of collaborative processes, such as network density, diversity, inclusion, and participation.

Leading global tax research from Singapore: The strategic partnership between SMU and the Tax Academy of Singapore

The Strategic Partnership between SMU and the Tax Academy of Singapore aims to boost ongoing discourse on global taxation issues through in-depth analyses of major developments. The partnership seeks to equip decision-makers with full background information necessary to make good tax decisions, contributing to the global tax academic c...

Air pollution may reduce health benefits of exercise

A new study found that long-term exposure to toxic air can weaken the health benefits of regular exercise. The study analyzed data from over 1.5 million adults and found that people living in high pollution areas had a reduced risk of dying, but not eliminated, despite exercising regularly. Clean air can still enhance health gains, wit...

Platform-independent experiment shows tweaking X’s feed can alter political attitudes

A new study using an AI-powered browser extension reveals that even small changes in exposure to hostile political content on X (formerly Twitter) can measurably influence feelings toward opposing political parties. The findings provide direct causal evidence of the impact of algorithmically controlled post ranking on a user's social m...

Study: New protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications

A new protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications, boosting survival rates while preserving anti-cancer immunity. The protocol, led by Robert Levy, uses TL1A-Ig fusion protein and low-dose IL-2 to stimulate specific receptors on Tregs, promoting a safer environment for stem cell transplants.

Hematological and biochemical serum markers in breast cancer: Diagnostic, therapeutic, and prognostic significance

Serum markers such as NLR, PLR, ESR, LDH, ALP, creatine kinase-BB, SUA, CRP, and CA 15-3/27.29 have been linked to breast cancer diagnosis, prognosis, and therapeutic monitoring. These biomarkers offer affordable, non-invasive, and accessible diagnostic strategies for bridging the diagnostic gap in low-resource settings.

The Lancet Respiratory Medicine: Monthly injection may help severe asthma patients safely reduce or stop daily oral steroid use

A new phase 3b clinical trial found that nearly 90% of severe asthma patients were able to reduce their steroid dose to a low dose after one year of treatment with the biologic medication Tezepelumab. The treatment also significantly improved asthma symptoms, lung function, and overall quality of life, while minimizing steroid use.
