With up to a million X-ray flashes a second, the laser will help study mechanisms in physics, chemistry, and biology.

The US Department of Energy’s (DOE) SLAC National Accelerator Laboratory has fired the first X-rays using the upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL), a press release said. The upgraded version, dubbed LCLS-II, was built for $1.1 billion.

Summary: The revolutionary field of bio-computing is making waves as DishBrain, a neural system combining 800,000 living brain cells, learns to play Pong. Recognizing the pressing need for ethical guidelines in this emerging domain, the pioneers behind DishBrain have joined forces with bioethicists in a study.

The research explores the moral considerations around biological computing systems and their potential consciousness. Beyond its innovation, the technology offers vast environmental benefits, potentially transforming the energy-consuming IT industry.

Penn State researchers have recently harnessed the biological concept for application in artificial intelligence to develop the first artificial, multisensory integrated neuron, which may forever change the world of AI and robotics.

Associate professor of engineering science and mechanics at Penn State Saptarshi Das explains: “Robots make decisions based on the environment they are in, but their sensors do not generally talk to each other. A collective decision can be made through a sensor processing unit, but is that the most efficient or effective method? In the human brain, one sense can influence another and allow the person to better judge a situation.”

Pigs with human kidneys? Brain-powered computer chips? Science is creating new kinds of living things – and our moral understanding needs to catch up fast.

The behaviors, physiology and existence of living organisms is supported by countless biological processes, which entail the communication between cells and other molecular components. These molecular components are known to transmit information to each other in various ways, for instance via processes know as diffusion and electrical depolarization or by exchanging mechanical waves.

Researchers at Yale University recently carried out a study aimed at calculating the energetic cost of this transfer of information between cells and molecular components. Their paper, published in Physical Review Letters, introduces a new tool that could be used to study cellular networks and better understand their function.

“We have been thinking about this project for a while now in one form or another,” Benjamin B. Machta, one of the researchers who carried out the study, told Phys.org.

Serious vision loss affects millions of Americans each year, and biological strategies are still decades away from restoring eyesight lost to macular degeneration. But University of Oregon researchers are looking to create an electronic solution — a bionic eye — that could restore people’s sight. They’re tapping into the world of fractal structures that will allow a retinal implant and a human brain to communicate with each other.

Scientists performed detailed 3D reconstructions of fossils discovered in Scotland.

Cyanobacteria, commonly known as blue-green algae, are the earliest known life forms on Earth. They are responsible for the Earth’s transition from a carbon dioxide-rich atmosphere to the present relatively oxygen-rich atmosphere due to oxygenic photosynthesis.

Ubiquitously found in ponds, lakes, water streams, rivers, and wetlands, they have played a significant role in shaping life.

The organism fared better at converting organic waste to electricity than even some famous and exotic electricity producing microbes.

Scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have successfully engineered E.coli.

Escherichia coli, commonly known as E.coli, is a rod-shaped bacterium commonly found in the lower gut of organisms. However, it has become a favorite of microbial researchers worldwide for the ease with which its genetic structure can be manipulated. It has, therefore, become an indispensable part of research and industrial projects.

Male fruit flies don’t usually like each other. Socially, they reject their fellow males and zero in on the females they discern via chemical receptors—or so scientists thought.

New research from Cornell University biologists suggests the fruit fly’s visual system, not just chemical receptors, are deeply involved with their social behaviors. The work sheds light on the possible origin of differences in human social behaviors, such as those seen in people with bipolar disorder and autism.

The paper is published in Current Biology.
