Sierra Space’s Dream Chaser is set to make its inaugural trip to orbit to deliver supplies to the International Space Station.

By Sarah Scoles

With its perpetually upturned pectoral fins, and blunt nose, the Dream Chaser looks more like a killer whale than a spacecraft. But unlike an orca, the Dream Chaser will soon be going to orbit: it’s set to take food and supplies to the International Space Station (ISS) later this year when it travels to space for the first time.

*BREAKTHROUGH!!*

Scientists may one day be able to freeze brains and bring them back to life following a major breakthrough in cryogenics.

Researchers in China have successfully frozen and thawed human brain tissue, after which it regained normal function.

A new concept called quantum spherical codes could make the notoriously fragile information in a photon-based quantum computer less susceptible to errors.

Many recent experiments have stored quantum information in bosonic modes, such as photons in resonators or optical fibres. Now an adaptation of the classical spherical codes provides a framework for designing quantum error correcting codes for these platforms.

Researchers at Linköping University in Sweden have developed a battery constructed from zinc and lignin that can be recharged over 8,000 times. This innovation aims to offer an affordable and eco-friendly battery alternative, especially for regions with limited electricity access. The findings are detailed in the journal Energy & Environmental Materials.

“Solar panels have become relatively inexpensive, and many people in low-income countries have adopted them. However, near the equator, the sun sets at around 6 PM, leaving households and businesses without electricity. The hope is that this battery technology, even with lower performance than the expensive Li-ion batteries, will eventually offer a solution for these situations,” says Reverant Crispin, professor of organic electronics at Linköping University.

Fruit fly study reveals brain-cell circuitry that could underlie how creatures large and small see wavelengths of light as information-rich hues.

Perceiving something – anything – in your environment means becoming aware of what your senses are detecting. Today, for the first time, Columbia University neuroscientists identify brain-cell circuitry in fruit flies that converts raw sensory signals into color perceptions that can guide behavior.

Their findings are published today (May 16) in the journal Nature Neuroscience.

UCLA Health researchers have identified a process that memories while reducing metabolic costs, even during sleep. This efficient memory is found in a brain region essential for learning and memory, which is also where Alzheimer’s disease originates.

The discovery is published in the journal Nature Communications.

Does this sound familiar: You go to the kitchen to fetch something, but when you get there, you forget what you wanted. This is your working memory failing. Working memory is defined as remembering some information for a short period while you go about doing other things. We use working memory virtually all the time. Alzheimer’s and dementia patients have working memory deficits and it also shows up in mild cognitive impairment (MCI). Hence, considerable effort has been devoted to understanding the mechanisms by which the vast networks of neurons in the brain create working memory.

Solid-state batteries store and release electric charge by moving ions back and forth between two electrodes. From our typical perspective, the ions flow through the battery’s solid electrolyte like a gentle stream.

But when seen on an atomic scale, that smooth flow is an illusion: Individual ions hop erratically from one open space to another within the electrolyte’s roomy atomic lattice, nudged in the direction of an electrode by a steady voltage. Those hops are hard to predict and a challenge to trigger and detect.

Now, in the first study of its kind, researchers gave the hopping ions a jolt of voltage by hitting them with a pulse of laser light. To their surprise, most of the ions briefly reversed direction and returned to their previous positions before resuming their usual, more random travels. It was the first indication that the ions remembered, in a sense, where they had just been.
