As any surfer will tell you, waves pack a powerful punch. We’re now making strides toward harnessing the ocean’s relentless movements for energy, thanks to advancements in “blue energy” technology. In a study published in ACS Energy Letters, researchers discovered that by moving the electrode from the middle to the end of a liquid-filled tube—where the water’s impact is strongest—they significantly boosted the efficiency of wave energy collection.

The tube-shaped wave-energy harvesting device improved upon by the researchers is called a liquid-solid triboelectric nanogenerator (TENG). The TENG converts mechanical energy into electricity as water sloshes back and forth against the inside of the tube. One reason these devices aren’t yet practical for large-scale applications is their low energy output. Guozhang Dai, Kai Yin, Junliang Yan, and colleagues aimed to increase a liquid-solid TENG’s energy harvesting ability by optimizing the location of the energy-collecting electrode.

Voice assistants have already made significant strides in areas such as smart home integration, educational settings and business applications. However, their current capabilities are limited by a lack of robust reasoning and planning abilities.

In fact, just 7.8% of consumers believe voice technology is as smart and reliable as a real person today, according to the PYMNTS Intelligence report “ How Consumers Want to Live in the Voice Economy.”

If we can prove the concept of this technology in the two diseases we’re studying, we can then apply it to hundreds or thousands of diseases of the brain.

A MUM who couldn’t sleep due to a “funny” whirring sound in her ear realised she had been hearing symptoms of her cancer after being diagnosed with a brain tumour.

Denise Wingfield, 55, was initially told dull noise in her right ear keeping her up at night was tinnitus, having been referred to an ear, nose and throat specialist.

“The problems arising when interpreting the data from WASP-39b are well known from many other exoplanets — regardless whether they are observed with Kepler, TESS, James Webb, or the future PLATO spacecraft,” said Dr. Nadiia Kostogryz.

While there is currently a myriad of techniques used to both discover exoplanets and calculate their physical characteristics, could other methods be developed to overcome specific data errors? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers investigated how a star’s magnetic field can be used to ascertain additional data for an exoplanet, which is traditionally done using conventional exoplanet detection methods, specifically the transit detection method. This study holds the potential to help astronomers establish new methods for discovering and characterizing exoplanets throughout the cosmos.

For the transit method, an exoplanet passes in front of its parent star, causing its starlight to slightly decrease and has been instrumental in discovering and characterizing thousands of exoplanets. However, astronomers have also discovered that a star’s limb darkening, which is the observed edge of the star, causes errors in transit light curves for exoplanets, despite using state-of-the-art atmospheric models to predict observations.

For the study, the researchers focused on WASP-39b, which is a gas giant located approximately 700 light-years from Earth and has been studied in great detail using a myriad of space telescopes, and most recently with NASA’s James Webb Space Telescope (JWST). However, astronomers have discovered inconsistencies between models and observations, which this study hopes to overcome.

How much of Venus’s atmosphere is being stripped by the Sun, and what can this tell us about how the planet lost its water long ago? This is what a recent study published in Nature Astronomy hopes to address as a team of international researchers examined data obtained from a 2021 Venus flyby by the BepiColombo spacecraft, which is a joint mission between the European Space Agency (ESA) and Japan Aerospace and Exploration Agency (JAXA) currently en route to Mercury. This study holds the potential to help researchers better understand the formation and evolution of planetary atmospheres, both within our solar system and beyond.

“Characterizing the loss of heavy ions and understanding the escape mechanisms at Venus is crucial to understand how the planet’s atmosphere has evolved and how it has lost all its water,” said Dr. Dominique Delcourt, who is a CNRS researcher at the Plasma Physics Laboratory (LPP) and the Principal Investigator of the Mass Spectrum Analyzer (MSA) instrument onboard BepiColombo, and a co-author on the study.

During its journey to Mercury, BepiColombo needs to conduct several gravity assists to slow down enough to enter Mercury’s orbit, with one such gravity assist occurring at Venus on August 10, 2021. During this flyby, BepiColombo passed through Venus’s magnetosheath, which is Venus’s version of a weak magnetic field that is produced by charged particles from the Sun interacting with Venus’s upper atmosphere. Over the course of 90 minutes, BepiColombo and its powerful instruments successfully measured data on how much atmospheric loss Venus is currently experiencing, which could help researchers better understand the formation and evolution of Venus’s atmosphere, and specifically how the planet lost its water long ago.

Acetaminophen exposure during pregnancy is not linked to the risk of developing autism, ADHD, or intellectual disability, according to a new study of data from more than 2 million children in Sweden. The collaborative research effort by Swedish and American investigators, which appears in JAMA, is the largest of its kind and was funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH).

An integrated plant that will remove 50,000 tonnes of carbon dioxide every year and create new freshwater from salty seawater is planned in the Daesan Industrial Complex in South Korea. When ready, this will be the world’s first such facility.

As countries work on their promises to go carbon neutral in a few decades, there is a strong push for innovative approaches that capture and utilize carbon. Carbon capture facilities work onsite to help reduce the release of carbon into the atmosphere. In contrast, direct air capture (DAC) technology focuses on removing the released carbon dioxide from the atmosphere.
