- 23/6/20 23:45
Engineers are placing low-powered sensors in the reflective raised pavement markers that are already used to help drivers identify lanes. Microchips inside the markers transmit information to passing cars about the road shape to help autonomous driving features function even when vehicle cameras or remote laser sensing, called LiDAR, are unreliable because of fog, snow, glare or other...

Anything with three hearts, blue blood and skin that can change colors like a display in Times Square is likely to turn heads. Meet Sepia bandensis, known more descriptively as the camouflaging dwarf cuttlefish. Over the past three years, neuroscientists have put together a brain atlas of this captivating cephalopod: a neuroanatomical roadmap depicting for the first time the brain's overall...

Insulin resistance is usually associated with type 2 diabetes. Now researchers have found it in cancer patients and learned that it can cause cancer to spread faster.
Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate
- ScienceDaily
- 23/6/20 23:44
A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and...
Scientists discover new embryonic cell type that self-destructs to protect the developing embryo

Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Environmental risks and opportunities of orphaned oil and gas wells
- ScienceDaily
- 23/6/20 23:44
Researchers are leading an international team whose goal is to create a framework to help governments in the U.S. and around the world assess and prioritize remediation strategies for orphaned oil and gas wells. These inactive wells represent environmental risks since they have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants that are...
Directly imaging quantum states in two-dimensional materials
When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found in other materials. However, these states are short lived and can change from one to another very quickly.
Scientists describe a novel way to manipulate exotic materials
An advance in a topological insulator material—whose interior behaves like an electrical insulator but whose surface behaves like a conductor—could revolutionize the fields of next-generation electronics and quantum computing, according to scientists at Oak Ridge National Laboratory.
Research identifies factors that make correcting misinformation about science more successful
In an article titled "A Meta-analysis of Correction Effects in Science-Relevant Misinformation" published in the journal Nature Human Behaviour, University of Pennsylvania social psychologists and communication scholars Man-pui Sally Chan and Dolores Albarracín explain the circumstances under which corrections of misinformation about science are most likely to work or fail, as well as the...
Topological bulk BICs enable compact, single-mode and beam-engineered QCLs
Electrically pumped semiconductor lasers are among the most important sources, owing to their high efficiency, compactness, and solid-state stability. For mid-infrared and terahertz radiation, quantum cascade lasers (QCLs) are the most important light sources operating via electrical pumping. To demonstrate single-mode laser emission, artificially designed distributed-feedback (DFB) gratings can...
Study: Microtargeting works, just not the way people think
Recent U.S. elections have raised the question of whether "microtargeting," the use of extensive online data to tailor persuasive messages to voters, has altered the playing field of politics.
A new adsorbent for removing radioactive cesium ions from nuclear wastewater
Nuclear power is typically considered a cleaner way of generating power compared to fossil fuels. It does not release air pollutants and greenhouse gasses like carbon dioxide as by-products. However, it creates radiotoxic waste that needs proper treatment to prevent adverse environmental and health conditions.
Media coverage of climate change research does not inspire action, say scientists
The planet is warming because of human activities and the consequences will be devastating for all living beings, including humans. At present, everyone is potentially exposed this information in the media. But how do scientific journals and the media relay research related to these issues? Is the scientific focus of climate warming research reflected in what the media decided to present?
Smart farming platform improves crop yields, minimizes pollution
A new farming system developed by researchers at The University of Texas at Austin aims to solve one of the biggest problems in modern agriculture: the overuse of fertilizers to improve crop yields and the resulting chemical runoff that pollutes the world's air and water.
Satellite captures carbon dioxide aurora from space
While the night sky, with its display of "northern lights" or auroras, has captivated the attention of scientists and sky gazers for centuries, much less is known about the aurora associated with carbon dioxide until now.
Even loyal customers distance themselves after socially unacceptable mentions of the brand on social media
Researchers from University of Arkansas and Northeastern University have published a new Journal of Marketing article that examines social media disengagement—the psychological motivation to distance oneself from a brand on social media.
Company culture shapes willingness of workers to act sustainably, research shows
Amidst rising concerns about the global climate crisis, Princeton researchers have uncovered the surprisingly large role that companies play in shaping sustainable behaviors among employees, as well as a link between eco-friendly behaviors and happier workers.
Study identifies most important factors in hotel guests' acceptance of AI technology
Over the past couple of years, artificial intelligence (AI) has greatly improved hotel operations and efficiency by automating processes such as booking and contactless check-in, allowing staff to focus on providing premium, personalized experiences to guests faster and at reasonable prices.
Brazilian fossil provides earliest evidence of evolutionary trait that enabled dinosaurs to become giants
The missing link has just been found between the earliest dinosaurs, whose size ranged from a few centimeters to at most three meters in length, and more recent giants that could be more than twice the length of a bus and have so much appeal to the popular imagination.

McGill University researchers are leading an international team whose goal is to create a framework to help governments in the U.S. and around the world assess and prioritize remediation strategies for orphaned oil and gas wells.
Computational mid-infrared photothermal imaging unveils intracellular tau aggregates
As a prominent form of amyloid protein, tau aggregates have emerged as a primary focus of research for uncovering the mechanisms underlying neurodegeneration. Various types of tau aggregates, including tau fibrils and oligomers, have been implicated in a wide range of neurodegenerative diseases. However, the formation mechanism of tau aggregates and the associated disease pathways remain poorly...
How scientific conferences are responding to abortion bans and anti-LGBTQ+ laws
When Claire Kouba heard that the American Geophysical Union’s (AGU’s) annual meeting would be held in New Orleans in 2025, she was worried. After the U.S. Supreme Court’s June 2022 decision overturning
Roe

In Montana lawsuit, a climate scientist takes the stand
Testimony ended today in a groundbreaking
climate lawsuit
being heard in a Montana state court. The suit, brought by 16 youth plaintiffs, argues that Montana’s energy policies contribute to climate change and therefore violate a right, enshrined in the state’s constitution, to “a clean and healthful environment.” It is the first youth-led climate lawsuit to be heard...
