Taking greater investment risks with technologies and new lines of business can help lower emissions from the aviation industry, one of the world’s fastest-growing sources of climate pollution, shows new research from UCD Michael Smurfit Graduate Business School.
The full article, “Mobilizing Capital and Technology for a Clean Aviation Industry,” was first published in Science, one of the world’s top academic journals.
Cutting planet-warming pollution to near-zero will take more than inventing new clean technologies; it will require changing how the world invests in them. That’s especially true for industries like aviation, where developing and adopting greener solutions is risky and expensive.
The new paper reveals that smarter ways of managing investment risk could help speed up the shift toward cleaner air travel and other hard-to-decarbonise sectors.
Dr Thomas Conlon, Professor of Finance from UCD Smurfit School, and co-authors propose a tool called an Aviation Sustainability Index (ASI); a quantitative method to assess how different technologies or investments could help decouple emissions from growth in air travel. The approach is designed to help investors distinguish between projects that only modestly improve efficiency and those that could significantly transform the sector’s climate impact.
While roughly $1 trillion is expected to flow into aviation over the next decade, most of that money will simply make aircraft slightly more efficient. Few investors have clear incentives to back the kind of breakthrough technologies, such as hydrogen propulsion, advanced aircraft designs, or large-scale sustainable fuel systems, that could substantially reduce emissions.
“Cleaner flight is possible, but it requires changing how we think about both risk and return,” says co-author David G. Victor, Professor of Innovation and Public Policy from the UC San Diego School of Global Policy and Strategy, and a leading voice in climate policy. “We need new institutions, incentives, and partnerships that reward innovation, not just incrementalism.”
“The technology to support clean aviation exists, but it requires a new way of framing the relationship between risk, return and sustainability,” says Dr Conlon. “Capital needs to flow towards risky innovations that will really move the dial in terms of deep decarbonisation. The proposed ASI provides a greenwashing resistant way to underpin sustainability linked financing to the sector, allowing investors to identify innovations will truly move the dial.”
The researchers also highlight a broader lesson for climate policy. Global decarbonisation goals such as “net zero by 2050” sound bold and ambitious, but when it becomes clear that they can’t be met, these goals make it harder to focus on the practical steps needed today to drive change in real-world markets.
By developing better tools to evaluate climate-friendly investments and by rewarding companies willing to take calculated risks on breakthrough technologies, governments, investors and industry leaders can accelerate real progress toward decarbonisation.
The paper was co-authored by Philipp Goedeking from Johannes Gutenberg University of Mainz (Germany) and Andreas W. Schäfer from University College London.

WASHINGTON, Oct. 21, 2025 — Measuring how well blood flows to the brain is crucial for understanding a wide range of neurological issues, from strokes to migraines to traumatic brain injuries. Obtaining such measurements noninvasively, however, remains a challenge. The scalp and skull not only obstruct viewing the brain directly but also have their own blood supply, further complicating cerebral blood flow measurements.

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, including magnetic resonance imaging and computed tomography, are expensive and therefore not widely available.
Researchers from the USC Neurorestoration Center and the California Institute of Technology (Caltech) have built a simple, noninvasive alternative. The device takes a technique currently used in animal studies known as speckle contrast optical ...

WASHINGTON, Oct. 21, 2025 — Seaweed is found around the world. In fact, the name “seaweed” comprises a diverse range of species, from microscopic phytoplankton to the giant forests found in various bodies of water.
Seaweed species aren’t just crucial parts of marine ecosystems, though; they also provide numerous health benefits for humans and have been dubbed a superfood by marketing companies, a term used to encompass healthy, nutrient-rich foods.

PROVIDENCE, R.I. [Brown University] — As more people turn to ChatGPT and other large language models (LLMs) for mental health advice, a new study details how these chatbots — even when prompted to use evidence-based psychotherapy techniques — systematically violate ethical standards of practice established by organizations like the American Psychological Association.
The research, led by Brown University computer scientists working side-by-side with mental health practitioners, showed that chatbots are prone to a variety of ethical violations. Those include inappropriately navigating crisis situations, ...

People who use both cannabis and tobacco show distinct brain changes compared to those who use cannabis alone, according to a new study led by McGill University researchers at the Douglas Research Centre.
The finding may help explain why people who use both cannabis and tobacco often report increased depression and anxiety, and why quitting cannabis is harder for them than for people only using cannabis
“This is the first evidence in humans of a molecular mechanism that may underlie why people who use both cannabis and tobacco experience worse outcomes,” said lead author Rachel Rabin, Associate Professor in McGill’s Department of Psychiatry ...

The ability of immune cells—particularly CD8+ T cells—to launch a rapid burst of proliferation inside tumors is key to the success of modern day cancer immunotherapies. However, the factors and mechanisms that drive this burst in proliferation remain poorly understood, making it difficult to predict which patients will benefit from treatment. A deeper understanding of this T cell burst could also guide the development of new therapies that enhance T cell proliferation and improve treatment outcomes.
To tackle this challenge, an international team of researchers led by Associate Professor Satoshi Ueha and Professor Kouji Matsushima from the Research ...

(WASHINGTON — October 21, 2025) – In pregnant women with sickle cell disease, the risk of developing early-onset preeclampsia can be determined by measuring levels of a protein associated with placental function and development. These findings provide insight that may help clinicians to anticipate and mitigate adverse pregnancy outcomes and were published in the journal Blood Advances.
“Patients with sickle cell disease are at high risk for developing preeclampsia, but the challenge is that these patients ...

Engineers at the University of California San Diego have created a new method to make large language models (LLMs) — such as the ones that power chatbots and protein sequencing tools — learn new tasks using significantly less data and computing power.
LLMs are made up of billions of parameters that determine how they process information. Traditional fine-tuning methods adjust all of these parameters, which can be costly and prone to overfitting — when a model memorizes patterns instead of truly understanding them, causing it to perform poorly on new examples.
The new method developed by UC San Diego engineers takes a smarter approach. ...
