We talked to Keith Thomas, the first paralysis patient to receive a movement and feeling-restoring double neural bypass surgery.
A recent Science Immunology Review suggests combining inhibitory strategies, such as ICI, alongside radiotherapy may counteract the creation of immunosuppressive adenosine during Cancer immunotherapy.

How reliable is your memory? Can you remember what you were doing on this day ten years ago? Or do you struggle to remember what you ate for lunch yesterday? Regardless of how well you think you remember things, all of our brains are full of memories of events that never happened – so-called false memories. And that, according to science, isn’t necessarily something to worry about.
To explain this strange phenomenon and much more, we talked to Dr Julia Shaw, a research associate at University College London and expert on criminal psychology.
Memories are essentially networks of neurons. And autobiographical memories – memories of our lives – involve connecting different parts of the brain. These memories don’t just live in one little piece.
Current Biology. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.
No bigger than a fingernail, these seemingly simple jellies have a complex visual system with 24 eyes embedded in their bell-like body. Living in mangrove swamps, the animal uses its vision to steer through murky waters and swerve around underwater tree roots to snare prey. Scientists demonstrated that the jellies could acquire the ability to avoid obstacles through associative learning, a process through which organisms form mental connections between sensory stimulations and behaviors.

In this video, we explore the biggest construction sites of the future — the ones that will one day provide us with real megastructures of all kinds and purposes.
From space elevators and Dyson spheres, to enormous ships and gargantuan space stations to live in. But we won’t just marvel at their scale — the real questions are: could we really build all these in the near future, what tech do we need to get the job done, and ultimately, will it work as intended, or these megastructures will turn out to be megagraves?
In our analysis we well use real engineering projects, as well as top sci-fi examples from books, movies and also from the unique world of massive multiplayer online game EVE Online.
In the 1950s, geologist Marie Tharp turned depth measurements into detailed maps of the ocean floor. It led to her discovery of the Mid-Atlantic rift.
There is a largely untapped energy source along the world’s coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate power.
A team of researchers at the University of Illinois Urbana-Champaign has reported a design for a nanofluidic device capable of converting ionic flow into usable electric power in the journal Nano Energy. The team believes that their device could be used to extract power from the natural ionic flows at seawater-freshwater boundaries.
“While our design is still a concept at this stage, it is quite versatile and already shows strong potential for energy applications,” said Jean-Pierre Leburton, a U. of I. professor of electrical & computer engineering and the project lead. “It began with an academic question—’Can a nanoscale solid-state device extract energy from ionic flow?’—but our design exceeded our expectations and surprised us in many ways.”
In a dramatic 13-minute plunge back to Earth, the OSIRIS-REx sample return capsule safely landed in Utah after seven years in space.
