(Press-News.org) Flexible electronics—including wearable devices, stretchable sensors, and soft robotics—require materials that integrate mechanical flexibility, stretchability, and durability with additional attributes like electrical conductivity. A review in the journal Small considers the potential of natural rubber as a sustainable resource to minimize the carbon footprint of flexible electronics.
The authors examine how natural rubber might be used in different types of flexible sensors, self-powered systems, and energy harvesting devices, and they consider possible modifications that might enhance natural rubber’s electrical and mechanical properties. The review also discusses challenges and opportunities associated with natural rubber–based flexible electronics, offering insights into future research and plausible commercial applications.
"For years, my research team has been working on the possibilities of using natural rubber and its derivatives for flexible sensors and triboelectric nanogenerators, and we have seen that the inherent properties of gum material can be tuned to generate a new class of sustainable material-based flexible electronics,” said corresponding author Titash Mondal, PhD, of the Indian Institute of Kharagpur. “We are working towards understanding further fundamentals associated with such a system and are making efforts to have an effective lab-to-market transition through appropriate partners.”

Could the timing of food assistance payments affect crime rates?
2025-08-06
Based on more than a decade’s worth of data across 36 U.S. states, a study in Contemporary Economic Policy finds that spreading out food assistance payments over more days reduces financially motivated crimes—especially robberies.
Compared with a single-day lump-sum monthly distribution through the Supplemental Nutrition Assistance Program (SNAP), a disbursement schedule consisting of 15 or more distribution days was associated with a decline of 0.03 robbery incidents per 100,000 population. Similarly, when SNAP distribution was staggered across 15 or more days, the incidence of robbery ...
Pollination behavior has huge role in plant evolution
2025-08-06
A new paper in Annals of Botany, published by Oxford University Press, indicates that pollination can have a dramatic effect on how plants grow and change. The study shows that when plants and pollinators become uncoordinated (even for a brief time) it can change who reproduces best and change plant diversity. The paper offers new insights into how evolution works in real time.
Pressures on pollination behavior can fluctuate over reproductive seasons, influencing which plants animals pollinate. Changes in the interaction between plants ...
Predicting respiratory disorder mortality in dogs
2025-08-06
Respiratory disorders in dogs can quickly become critical and are reported to be the second leading cause of cardiac arrest in canines. Therefore, it is necessary to take appropriate measures according to each patient’s condition. This, however, requires rapid and accurate disease severity assessments. In human medicine, scoring systems that incorporate physical examinations and blood tests results with respiratory function assessments exist, and enable more accurate severity assessments. In contrast, there are only a few reports on severity assessments that use tests other than respiratory function evaluations in veterinary medicine. Further, these evaluations usability ...
Living in hurricane affected areas could increase mortality of older people by 9% years after disaster
2025-08-06
Hurricanes and related natural catastrophes like flooding are becoming more severe and more frequent around the world. Older people are especially at risk, but relatively little is known about long-term health effects. In 2012, the north-east US was hit by Hurricane Sandy, which resulted in unusable transportation systems, destruction of homes, power loss, and more than 100 casualties.
But what about the people who continue living in hurricane-mangled areas? Now, researchers in the US have investigated if ...
New risk calculator can better predict stroke to direct the best prevention
2025-08-06
BURLINGTON—Researchers at the University of Vermont have developed a more precise way to assess stroke risk in people with atrial fibrillation (A-Fib), a condition that affects 10.5 million Americans and is a leading cause of stroke.
Their findings, published August 6 in the Journal of Thrombosis and Haemostasis, show that adding simple blood tests to an existing risk calculator can help physicians better determine who truly needs anticoagulant medications—powerful drugs that prevent strokes but ...
Social media boosts news diversity amid traditional media decline
2025-08-06
New research by the University of South Australia finds a silver lining to the struggling media landscape in the face of the digital age, revealing that social media is enhancing the diversity of news the community receives.
The study found that Australian news is more diverse on social media, as the traditional media landscape – particularly quality local journalism – has become increasingly unsustainable.
Social media is the most popular way for Australians to find and consume news, ...
HOXB13 in cancer development: molecular mechanisms and clinical implications
2025-08-06
HOXB13, a B-class homeobox transcription factor, sits at the hub of developmental gene networks yet has emerged as a double-edged sword in human cancer. While indispensable for embryonic patterning and androgen-dependent organogenesis, its expression is frequently hijacked or extinguished by epigenetic, mutational and post-translational events that drive tumour initiation, progression and therapy resistance. Across more than twenty malignancies, the protein acts as either oncogene or tumour suppressor, depending on tissue context, interacting partners and mutational ...
Research shows Alaska early quake warning system could provide critical seconds
2025-08-06
A proposed earthquake early warning system could have provided several communities an alert of 10 seconds or more ahead of strong shaking from the magnitude 7.3 quake that occurred south of Sand Point near the tip of the Alaska Peninsula in mid-July.
That analysis is provided by Alex Fozkos of the Alaska Earthquake Center’s systems team at the University of Alaska Fairbanks Geophysical Institute.
“Individuals in Sand Point could have expected approximately 10 seconds of warning time before ...
Researchers discover universal laws of quantum entanglement across all dimensions
2025-08-06
A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online on August 5, in Physical Review Letters as an Editors’ Suggestion.
“This study is the first example of applying thermal effective theory to quantum information. The results of this study demonstrate the usefulness of this approach, and we hope to further develop this approach to gain a deeper understanding of quantum entanglement structures,” ...
Emeishan mantle plume created 400 km gas-rich carbonate belt in Sichuan Basin
2025-08-06
Beneath the modern Sichuan Basin lies a geological masterpiece orchestrated by the Emeishan mantle plume 262 million year ago. A landmark study published in the Journal of Palaeogeography (Chinese Edition) uncovers how plume-driven tectonics shattered a Permian carbonate ramp into a complex platform system, creating a 400-kilometer-long dolostone hydrocarbon reservoir belt now pivotal to China’s energy exploration. Led by Prof. Yuan Haifeng (Chengdu University of Technology) and Dr. Zhang Benjian (PetroChina Southwest ...
