Venture debt acts as a bridge between funding stages for tech startups, global study finds

Heriot-Watt University
Peer-Reviewed Publication

Research across 59 countries shows venture debt reshapes startup finance by reducing early-stage equity, increasing late-stage investment, and expanding the total pool of capital

A new international study has found that venture debt is reshaping how capital moves through technology startup ecosystems around the world. Analysing data from 59 countries between 2015 and 2024, the researchers show that greater venture debt availability is associated with lower early-stage equity funding, higher late-stage equity funding and a positive overall effect on the total capital available to startups.

Published in International Review of Economics and Finance by researchers from the Edinburgh Business School based at Heriot-Watt University, the study is the first to provide an international comparison of venture debt and its influence on equity funding. The research argues that venture debt should not be seen as a passive supplement to equity, but as a strategic financial instrument that can reshape innovation pathways.

Wet coffee grounds turned into high-grade solid fuel in just 90 seconds

National Research Council of Science & Technology
Peer-Reviewed Publication

A Researcher team at the Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed a technology that converts wet spent coffee grounds directly into high-quality biochar in just 90 seconds, no drying or oil removal required. The breakthrough offers a fast, energy-efficient path to turning high-moisture organic waste into valuable fuel and carbon materials.

The study, led by Dr. Taejun Park in collaboration with GodTech Co., Ltd., was published in the Chemical Engineering Journal (Elsevier), one of the world's leading journals in chemical engineering.

Electrically tunable “super-lasers”

University of Warsaw, Faculty of Physics
Peer-Reviewed Publication

A team of physicists from the University of Southampton (UK), University of Warsaw (PL), Military University of Technology (PL), Institut Pascal, Université Clermont Auvergne, CNRS (FR), and CNR (IT) has developed a new class of tunable photonic devices in which multiple tiny laser beams spontaneously synchronize and behave as a unified, spatially extended, and coherent light source. Remarkably, this effect is achieved at room temperature using a simple system based on liquid crystals and organic dye molecules, opening new possibilities for low-cost and reconfigurable optical technologies.

Oil palm, coconut and soybean cause more species extinction than thought

ETH Zurich
Peer-Reviewed Publication

Oil crops cause a loss of around 1.5 percent of animal and plant species. This is the conclusion of a new study. According to the study, the biodiversity loss caused by oil crops has increased by around 80 percent since 1995. The key driver is per-capita consumption and not global population growth.

A light-color-programmed artificial synapse for brain-like balanced learning

Sungkyunkwan University External Affairs Division (PR team)
Peer-Reviewed Publication

The human brain actively keeps “learning” in balance, by holding on to what matters and letting go of what does not. Researchers in Korea have now reproduced this ability in a semiconductor device, using the color of light to strengthen (remember) or weaken (forget) an artificial synapse's memory.
