Weighing in on a Mars water debate

Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet's crust is still unclear, according to a new analysis.

TOI-1453: Sub-Neptune in system of two exoplanets

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future atmospheric studies to better understand these types of planets.

Spinning, twisted light could power next-generation electronics

Researchers have advanced a decades-old challenge in the field of organic semiconductors, opening new possibilities for the future of electronics. The researchers have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such as spintronics and quantum computing.

Black holes: not endings, but beginnings? New research could revolutionize our understanding of the universe

New research suggests black holes may transition into 'white holes', ejecting matter and potentially even time back into the universe, defying our current understanding of these cosmic giants.

Small, faint and 'unexpected in a lot of different ways': Astronomers make galactic discovery

The discovery of the dwarf galaxy Andromeda XXXV --located roughly 3 million light-years away and the smallest yet found in the Andromeda system -- is forcing astronomers to rethink how galaxies evolve in different cosmic environments and survive different epochs of the universe.

How climate change affects rain and floods

Climate change may lead to more precipitation and more intense floods. A new study shows that to understand the details of this relationship, it is important to distinguish between different types of rainfall and flood events -- namely, between short-term events that occur on a time scale of hours, and longer-term events that last several days. In each case, climate change has a different impact.

technique to manipulate water waves to precisely control floating objects

Where there's water, there are waves. But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to produce complex patterns, such as twisting loops and swirling vortices. Some patterns acted like tweezers or a 'tractor beam' to hold a floating ball in place. Other patterns made the ball spin and move precisely in a circular path. In the future, the technique could be scaled down to precisely move particles the size of cells for experiments, or scaled up to guide boats along a desired path on the water.
