Phys.org / Greenwashing firms are scrutinized less if they are in politicians' pockets, study finds
Companies with strong political connections are more likely to escape scrutiny over greenwashing, according to new research from Durham University Business School. Greenwashing occurs when organizations overstate or misrepresent ...
Phys.org / An echo of Einstein: An unexpected link between whale calls and special relativity
Standing on the sandy, windswept shores of Provincetown, Massachusetts, people may find themselves squinting at the horizon, waiting for a whale to make its grand entrance with a spectacular breach.
Phys.org / Volcano myths unravel, from 'smoke' plumes to Yellowstone catastrophe claims
Volcanoes emit smoke. Beneath a volcano lies a huge chamber filled with liquid magma. A series of earthquakes means an eruption is imminent. And if a "supervolcano" like Yellowstone were to awaken, a global catastrophe would ...
Tech Xplore / Inexpensive reflective tiles pave the way for millimeter wave wireless communications
Unlike Wi-Fi or cellular signals, millimeter-wave wireless communication channels are unable to pass through walls, furniture or other objects. This reality is part of what is holding back the implementation of millimeter-wave ...
Medical Xpress / Cell-preservation technique could make CAR-T cell therapy more accessible
Immune cells that are engineered to attack cancer cells, known as CAR-T cells, are used to treat some types of blood cancer. However, only about 5% of hospitals in the United States can generate and deliver CAR-T cells to ...
Phys.org / Why many birds add fresh plants to their nests remains unclear despite signs of healthier offspring
As they build their nests, many birds are known to interweave dried grasses and other materials with green plants, such as fresh leaves, grass stems, herbs and aromatic leaves. While this behavior is well documented, why ...
Phys.org / Italian scientists bet on octopus to fight crab invasion
From a fishing trawler in the Adriatic, Italian scientists gently release thousands of tiny octopuses in the hope of fighting an invasive crab species that has devastated local fisheries.
Phys.org / What if our cities were designed for wildlife as well as people?
On a warm evening in May, swifts scream over rooftops, chasing insects above the traffic. A fox slips along a garden wall while gulls squabble on a supermarket roof. We tend to treat these animals as visitors. But they're ...
Tech Xplore / 'Oxygen tunnel' structure could solve 3D memory reliability problem to boost AI chip performance
As AI systems become more advanced, memory is required to transfer larger amounts of data at higher speeds. But conventional planar semiconductor scaling is running out of room. A KAIST research team has now addressed a key ...
Phys.org / Jellyfish reveal how rapid cell turnover may suppress early cancer growth
Although increased cell proliferation is a hallmark of cancerous tissues, in some cases it may actually protect against tumor growth, according to a new study by Caltech researchers. Using mathematical models, the work suggests ...
Phys.org / Peru's highest mountain confirms tropics were a major methane source before the industrial era
A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.
Medical Xpress / Gut bacteria may transform spinach, beets and plant iron into protective compounds
Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
