How Many Exoplanets are Hiding in Dust?

Universe Today Feed - Wed, 04/09/2025 - 11:14pm

What can exozodiacal dust, also called exozodi, teach astronomers about identifying Earth-like exoplanets? This is what a recently submitted NASA white paper—which highlights key findings from the annual Architecture Concept Review—hopes to address as a team of researchers discussed how exozodi orbiting within a star’s habitable zone (HZ) could interfere with detecting Earth-like exoplanets. This study has the potential to help scientists better understand observational constraints of observing Earth-like exoplanets and what improvements could be made for future telescopes and instruments to overcome these constraints.

'Hidden galaxies': Key to unlocking some of universe's secrets

Space and time from Science Daily Feed - Wed, 04/09/2025 - 6:25pm
Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it would 'effectively break current models of galaxy numbers and evolution'. The possible galaxies may also provide the missing piece of the puzzle for the energy generation in the universe in infrared light. That's because their combined light would be enough to top-up the energy budget of the universe to the maximum we observe, effectively accounting for all remaining energy emission at these long wavelengths.

Why quantum computers may continue to fail a key test

New Scientist Feed - Wed, 04/09/2025 - 5:35pm
There have been several claims of quantum computers performing at a level impossible to match with a classical computer – most of which have been refuted. Could there be a mathematical reason why this keeps happening?

Bio-oils for greener industrial applications

Matter and energy from Science Daily Feed - Wed, 04/09/2025 - 2:31pm
New technology could enable more sustainable and cheaper production of bio-oils to replace petroleum-based products in electronic, construction and automotive applications. The technology, known as PYROCOTM, uses high temperatures without oxygen to convert treated sewage (biosolids) into a carbon-rich product called biochar, which can act as a catalyst to produce phenol-rich bio-oil.

3D streaming gets leaner by seeing only what matters

Matter and energy from Science Daily Feed - Wed, 04/09/2025 - 12:50pm
A new approach to streaming technology may significantly improve how users experience virtual reality and augmented reality environments, according to a new study. The research describes a method for directly predicting visible content in immersive 3D environments, potentially reducing bandwidth requirements by up to 7-fold while maintaining visual quality.

A new robotic gripper made of measuring tape is sizing up fruit and veggie picking

Matter and energy from Science Daily Feed - Wed, 04/09/2025 - 12:46pm
It's a game a lot of us played as children -- and maybe even later in life: unspooling measuring tape to see how far it would extend before bending. But to engineer, this game was an inspiration, suggesting that measuring tape could become a great material for a robotic gripper. The grippers would be a particularly good fit for agriculture applications, as their extremities are soft enough to grab fragile fruits and vegetables, researchers wrote. The devices are also low-cost and safe around humans.

A new smartphone-sized device can test for tuberculosis: Here's why that matters for children

Matter and energy from Science Daily Feed - Wed, 04/09/2025 - 12:46pm
This handheld device is the first that can detect tuberculosis in saliva, in addition to blood and sputum samples, an important breakthrough for testing children and HIV patients, who struggle to produce sputum. The device was found to deliver rapid, accurate results in under an hour, offering a cost-effective and accessible solution for diagnosing TB in resource-limited areas.

Flocks of CubeSats Can Efficiently Monitor Farms

Universe Today Feed - Wed, 04/09/2025 - 11:56am

The widespread use of low Earth orbit (LEO), especially by thousands of CubeSats, has opened up many opportunities in research and business applications. One particular field that has benefited from the data that CubeSats provide is farming. Precision agriculture (PA) is a technique that uses advanced sensors, including the remote ones on CubeSats, to determine the health and productivity of a farm. A recent review paper from Lamia Rahali and her co-authors at the Mediterranea University of Reggio Calabria's Department of Agriculture looks at how CubeSats have been changing the practice of precision agriculture - and how they may continue to do so.
