Oakland is now first in the US to have a 100% electric school bus fleet — and it’s V2G

Posted by in categories: education, robotics/AI, sustainability, transportation

An Oakland, California, school district is the first in the US to transition to a 100% electric school bus system with vehicle-to-grid (V2G) technology.

Modern student transportation platform Zum has provided Oakland Unified School District with a fleet of 74 electric school buses and bidirectional chargers. Utility Pacific Gas and Electric (PG&E) supplied 2.7 megawatts (MW) of load to Zum’s Oakland EV-ready facility. The fleet will be managed through Zum’s AI-enabled technology platform.

“Oakland becoming the first in the nation to have a 100% electric school bus fleet is a huge win for the Oakland community and the nation as a whole,” said Kim Raney, executive director of transportation at Oakland Unified School District. “The families of Oakland are disproportionately disadvantaged and affected by high rates of asthma and exposure to air pollution from diesel fuels.”

The New ‘Dream Chaser’ Spacecraft Prepares to Visit the International Space Station

Posted by in categories: food, space

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.

Frozen brain tissue brought back to life in major breakthrough

Posted by in categories: innovation, neuroscience


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.

Quantum spherical codes

Posted by in categories: computing, quantum physics

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.

Revolutionizing Renewable Energy: Scientists Develop New Low-Cost Battery With Over 8000 Uses

Posted by in categories: business, solar power, sustainability

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.

From Light to Insight: Columbia Researchers Illuminate the Mysteries of Visual Perception

Posted by in category: neuroscience

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.

Spontaneous Persistent Inactivity — Scientists Discover New Type of Memory State

Posted by in categories: biotech/medical, health, 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.
