Read this aloud and your inner ear, by itself, will be carrying out at least the equivalent of a billion floating-point operations per second, about the workload of a typical game console. The inner ear together with the brain can distinguish sounds that have intensities ranging over 120 decibels, from the roar of a jet engine to the rustle of a leaf, and it can pick out one conversation from among dozens in a crowded room. It is a feat no artificial system comes close to matching.

Waiting for Superbatteries

They are still a long way from matching the energy density of liquid fuel

A man dressed in black is seen from above at the right-hand side of a white table divided into six rectangles, their longer sides running left and right of the man—that is, up and down, from the reader’s point of view. A narrow arm, framed in orange, extends from left to right down the middle of the table, crossing the rectangles; the man is working on the right-hand side of the arm, which contains electrical apparatus.

If grain must be dragged to market on an oxcart, how far can it go before the oxen eat up all the cargo? This, in brief, is the problem faced by any transportation system in which the vehicle must carry its own fuel. The key value is the density of energy, expressed with respect to either mass or volume.

The era of large steam-powered ocean liners began during the latter half of the 19th century, when wood was still the world’s dominant fuel. But no liners fired their boilers with wood: There would have been too little space left for passengers and cargo. Soft wood, such as spruce or pine, packs less than 10 megajoules per liter, whereas bituminous coal has 2.5 times as much energy by volume and at least twice as much by mass. By comparison, gasoline has 34 MJ/L and diesel about 38 MJ/L.

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. The answer is a nuanced “perhaps.” It depends on several factors, including the speed of grid-component modernization, the volume of EV sales, where they occur and when, what kinds of EV charging are being done and when, regulator and political decisions, and critically, economics.

The city of Palo Alto, Calif. is a microcosm of many of the issues involved. Palo Alto boasts the highest adoption rate of EVs in the United States: In 2020, one in six of the town’s 25,000 households owned an EV. Of the 52,000 registered vehicles in the city, 4,500 are EVs, and on workdays, commuters drive another 3,000 to 5,000 EVs to enter the city. Residents can access about 1,000 charging ports spread over 277 public charging stations, with another 3,500 or so charging ports located at residences.

NYU Biomedical Engineering Speeds Research from Lab Bench to Bedside

Intensive clinical collaboration is fueling growth of NYU Tandon’s biomedical engineering program

This optical tomography device that can be used to recognize and track breast cancer, without the negative effects of previous imaging technology. It uses near-infrared light to shine into breast tissue and measure light attenuation that is caused by the propagation through the affected tissue.

When Andreas H. Hielscher, the chair of the biomedical engineering (BME) department at NYU’s Tandon School of Engineering, arrived at his new position, he saw raw potential. NYU Tandon had undergone a meteoric rise in its U.S. News & World Report graduate ranking in recent years, skyrocketing 47 spots since 2009. At the same time, the NYU Grossman School of Medicine had shot from the thirties to the #2 spot in the country for research. The two scientific powerhouses, sitting on opposite banks of the East River, offered Hielscher a unique opportunity: to work at the intersection of engineering and healthcare research, with the unmet clinical needs and clinician feedback from NYU’s world-renowned medical program directly informing new areas of development, exploration, and testing.
