E. Coli calculus: Bacteria find the derivative optimally

Scientists from the Graduate School of Information Science and Technology at The University of Tokyo calculated the efficiency of the sensory network that bacteria use to move towards food and found it to be optimal from an information theory standpoint. This work may lead to a better understanding of bacterial behavior and their sensory networks.

Searching for hints of new physics in the subatomic world

Peer deeper into the heart of the atom than any microscope allows and scientists hypothesize that you will find a rich world of particles popping in and out of the vacuum, decaying into other particles, and adding to the weirdness of the visible world. These subatomic particles are governed by the quantum nature of the Universe and find tangible, physical form in experimental results.

New machine learning tool diagnoses electron beams in an efficient, non-invasive way

Beams of accelerated electrons power electron microscopes, X-ray lasers, medical accelerators and other devices. To optimize the performance of these applications, operators must be able to analyze the quality of the beams and adjust them as needed.

Effective Field Theories and the nature of the universe

What is the world made of? This question, which goes back millennia, was revisited by theoretical physicist Steven Weinberg from the University of Texas in Austin, TX, USA in the first of an international seminar series, 'All Things EFT.' Weinberg's seminar has now been published as an article in the journal EPJ H.

Astronomy and Space news

Astronomers discover four new 'hot Jupiters'

An international team of astronomers has detected four new "hot Jupiter" exoplanets as part of the Next Generation Transit Survey (NGTS). The newly found alien worlds are at least 10% larger than Jupiter but less massive than the solar system's biggest planet. The finding is reported in a paper published March 18 on arXiv.org.

Astronomers image magnetic fields at the edge of M87's black hole

The Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole, has today revealed a new view of the massive object at the center of the Messier 87 (M87) galaxy: How it looks in polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.

Study finds new inroads in fast charging for lithium-ion batteries

Perhaps the most frustrating limitation of owning an all-electric car is how long it takes to fully charge the battery. For a Tesla, for example, it takes about 40 minutes to charge it to 80% capacity using the most powerful charging station.

Mixed reality gets a machine learning upgrade

Scientists from the Division of Sustainable Energy and Environmental Engineering at Osaka University employed deep learning artificial intelligence to improve mobile mixed reality generation.

This work may lead to a revolution in green architecture and city revitalization.

Dow-like index for energy prices might help smooth transition to clean power

Since the early industrial revolution in the mid-1700s, fossil fuels have acquired an ever-growing footprint in energy production. However, the environmental concerns of fossil fuels use and their inevitable depletion have led to a global shift toward renewable energy sources. These transitions, however, raise questions about the best choice of renewables and the impact of investing in these resources on consumer cost.

Knitting roads: Digitalized road construction uses no concrete

A robotic arm lays out a string in a mandala-like pattern on a bed of gravel. What appears to be a contemporary art performance is basic research that explores new ways in road construction. On the one hand, robot-assisted construction techniques for road building are being tested that have so far only been used in structural engineering. On the other hand, a new type of mechanical reinforcement is intended to change the typical structure of the road surface and thus to help save valuable resources in future or even to recycle road surfaces altogether.

Spotting and stopping online abuse

Social media has brought huge benefits to many of those around the world with the resources to access its apps and websites. Indeed, there are billions of people using the popular platforms every month in almost, if not, every country of the world.

New fire-simulating tool could improve in-flight fire safety

Some of the most dangerous fires are the ones you don't see coming. That goes not only for fires in buildings but for those kilometers off the ground, aboard commercial airliners. Many aircraft have systems to detect fires early on, but fires that spark in their attics, or overhead compartments—spaces with curved ceilings, filled with air ducts, electrical wiring and structural elements—could potentially sneak past them.

Support system to help the visually impaired navigate tactile paving

Sight is by far the sense that we humans use the most when navigating an environment. When those who are blind or visually impaired walk alone, they put themselves at great risk of falling or colliding with obstacles, especially when traversing new places. Unfortunately, the number of visually impaired people throughout the world is likely to increase in the near future because of the rapidly aging population. Thus, there is an urgent need for innovative and cost-effective solutions to help visually impaired people navigate safely.
