But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter?

Key Points: 
  • But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter?
  • I first learned of this area of research as a graduate student in physical chemistry.
  • Before understanding why attosecond research resulted in the most prestigious award in the sciences, it helps to understand what an attosecond pulse of light is.
  • So a flash of light lasting an attosecond, or 0.000000000000000001 of a second, is an extremely short pulse of light.

SEATTLE, Sept. 26, 2023 /PRNewswire/ -- A complete map of all the connections in an entire mammalian brain may be in sight. Allen Institute researchers have just launched three new projects to construct large, detailed maps of neuronal connections in sections of the mouse and macaque brains, with an eye toward creating full wiring diagrams of these animals' brains in the future. These projects are funded by the National Institutes of Health's Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative.

Key Points: 
  • SEATTLE, Sept. 26, 2023 /PRNewswire/ -- A complete map of all the connections in an entire mammalian brain may be in sight.
  • These projects are funded by the National Institutes of Health's Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative .
  • The goal will be to use this pipeline to image an entire hemisphere of a mouse brain at 120 nanometer resolution and the cortical basal ganglia thalamic loop (up to 10 mm3) in very fine detail to better understand how the mouse brain functions.
  • "We can actually map the whole macaque brain in a few years instead of 100 years.

Lithium-ion battery fires are a growing public safety concern − here's how to reduce the risk

Compared with the lead-acid versions that have dominated the battery market for decades, lithium-ion batteries can charge faster and store more energy for the same amount of weight.

Key Points: 
  • Compared with the lead-acid versions that have dominated the battery market for decades, lithium-ion batteries can charge faster and store more energy for the same amount of weight.
  • These devices make our electronic gadgets and electric cars lighter and longer-lasting – but they also have disadvantages.

A new fire hazard

    • As concerns grow in cities around the world about climate change and air quality, electric vehicles have taken center stage.
    • At the same time, e-bikes and electric scooters are transforming urban transit by providing convenient, low-carbon ways to navigate crowded streets and reduce traffic congestion.
    • Fire departments in New York City and San Francisco report handling more than 660 fires involving lithium-ion batteries since 2019.
    • Clearly, there is a need for safer handling and charging practices, as well as technical improvements to batteries.

Many batteries in an EV

    • A battery holds chemicals that contain energy, with a separator between its positive and negative electrodes.
    • Depending on its design, an EV may contain dozens to thousands of single batteries, which are known as cells.
    • A standard EV will contain one large battery pack with many cells inside it.

What causes battery fires

    • Typically, a battery fire starts in a single cell inside a larger battery pack.
    • Battery short circuits may be caused by faulty external handling or unwanted chemical reactions within the battery cell.
    • Another factor that makes lithium-ion battery fires challenging to handle is oxygen generation.
    • Fires need oxygen to burn, so a battery that can create oxygen can sustain a fire.

Managing the thermal runaway problem

    • However, these mechanisms make the battery larger and heavier, which can reduce the performance of the device it powers.
    • And they may not be reliable under extreme temperatures or pressures, such as those produced in a car crash.
    • Making a thermal runaway in a battery pack less intense requires a mix of software and hardware improvements.
    • Park the vehicle away from extremely hot or cold surroundings – for example, park in shade during heat waves – to prevent thermal stress on the battery.
