Found in space: Complex carbon-based molecules

Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons (PAHs). Since the 1980s, circumstantial evidence has indicated that these molecules are abundant in space, but they have not been directly observed.

Powerful stratospheric winds measured on Jupiter for the first time

Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, a team of astronomers has directly measured winds in Jupiter's middle atmosphere for the first time. By analyzing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful winds, with speeds of up to 1450 kilometers an hour, near Jupiter's poles. They could represent what the team have described as a "unique meteorological beast in our solar system."

Study finds that wind energy output increases when people need heat the most

In response to the recent freeze-inspired power outages in Texas, some politicians blamed the historic blackouts on wind turbines. The dubious, and largely dismissed, claims nevertheless spotlighted an intriguing fact: Texas, the land made famous by oil derricks and wildcatters, now gets a significant portion of its electricity from clean, renewable sources, most notably wind, but also from water and solar—a troika of sustainability known collectively as WWS.

New perovskite fabrication method for solar cells paves way to large-scale production

A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade.

What the drive for open science data can learn from the evolving history of open government data

Nineteen years ago, a group of international researchers met in Budapest to discuss a persistent problem. While experts published an enormous amount of scientific and scholarly material, few of these works were accessible. New research remained locked behind paywalls run by academic journals. The result was researchers struggled to learn from one another. They could not build on one another's findings to achieve new insights. In response to these problems, the group developed the Budapest Open Access Initiative, a declaration calling for free and unrestricted access to scholarly journal literature in all academic fields.

Textnets: Software to make large amounts of text visually comprehensible

Software development is probably not the first thing that comes to mind when you think of a sociologist. Three years ago, John Boy began developing his software package Textnets. Because of COVID, he was less able to concentrate on writing scientific research and also setting up the online courses required a lot of energy. However, the one thing he could really focus on during the lockdown was programming. And so, during some of the few hours at his desk, Boy worked on Textnets, an open source program for analyzing large amounts of text documents and making them visually comprehensible.

Safety concerns determine level of public support for driverless vehicles, finds study

When it comes to the use of driverless vehicles, an individual's support for their adoption hinges on how safe they are, rather than their economic impact or privacy concerns stemming from the data they might collect, a Nanyang Technological University, Singapore (NTU Singapore) study of 1,006 Singaporeans has found.

Using ships themselves to monitor and predict waves

Shipping provides the very foundation for world trade, by moving an estimated 11 billion tons of goods a year from where they are produced to where they will be used. From TVs to toasters, soap to sugar—much of it moves over the waves.

AI developers often ignore safety in pursuit of breakthrough—so how do we regulate them without blocking progress?

Researchers have been exploring the approach for harnessing ocean energy to solve the world energy crisis and pollution problems caused by thermal power generation. The nanogenerator, including piezoelectric, triboelectric, and pyroelectric nanogenerators, is one of the key technologies for mechanical energy conversion. The triboelectric nanogenerator (TENG) makes use of the triboelectric effect and electrostatic induction to harvest mechanical energy based on contact or sliding electrification.
