An inventor, molecular biologist, and diagnostic scientist, Dr. Todd cofounded SpeeDx, which serves communities worldwide. And that’s just the beginning.
While the chemistry is different from traditional lithium-ion batteries, it’s part of a power pack with big advantages, including greater energy storage (estimated at up to 15 times that of lithium-ion) in relation to mass, a metric referred to as energy density.
Other perks include easy recyclability, being planet-friendly, and being cost-effective, per the ET report, which was written with benefits to the Indian market in mind.
“It is a long-range, budget-friendly, lightweight, and recyclable source of energy that can arguably be a saviour in the EV market,” Kriti Saraiya wrote for ET.

Graphene’s atomically thin structure makes it impenetrable to a variety of elements, including protons. However, graphene’s edges, flaws, and functionalization can open up channels for proton diffusion. Temperature, humidity, and the existence of functional groups are some of the variables that affect the flow of protons in graphene.
AI is already transforming the way we search, gather information, create, code, decipher data and more, and now it may democratize the process of building an app, too. A new AI-powered startup called Sutro promises the ability to build entire production-ready apps — including those for web, iOS and Android — in a matter of minutes, with no coding experience required.
The idea is to allow founders to focus on their unique ideas by leaning on Sutro to automate other aspects of app building, including the necessary AI expertise, product management and design, hosting, use of domain-specific languages, compiling and scaling.
The company was founded in late 2021 by Tomas Halgas, who sold his previous startup, the group chat app Sphere, to Twitter, alongside former Google and Facebook Product Manager Owen Campbell-Moore. The two have taken turns running the company, with Campbell-Moore at the head while Halgas worked at Twitter in its chaotic days leading up to Elon Musk’s takeover. Now, with Halgas having departed Twitter, he’s acting as CEO as Campbell-Moore has shifted to a day job at OpenAI.

What if the song “Baby Shark” stopped after just two stanzas?
For non-fans of the catchy tune, that might sound like a dream. For a real-life Mommy Shark in Illinois, it’s reality: She produced a baby without a Daddy Shark.

But the catastrophe will not be limited to those two belligerents and their allies.
The long-term regional and global effects of nuclear explosions have been overshadowed in public discussions by the horrific, obvious, local consequences of nuclear explosions. Military planners have also focused on the short-term effects of nuclear explosions because they are tasked with estimating the capabilities of nuclear forces on civilian and military targets. Blast, local radiation fallout, and electromagnetic pulse (an intense burst of radio waves that can damage electronic equipment) are all desired outcomes of the use of nuclear weapons—from a military perspective.
But widespread fires and other global climatic changes resulting from many nuclear explosions may not be accounted for in war plans and nuclear doctrines. These collateral effects are difficult to predict; assessing them requires scientific knowledge that most military planners don’t possess or take into account. Yet, in the few years following a nuclear war, such collateral damage may be responsible for the death of more than half of the human population on Earth.

Announced on the DARPA website on the 1st of November 2023, the chosen few will design and build a prototype vertical takeoff and landing aircraft (VTOL) “to demonstrate the key technologies and integrated concepts that enable a transformational combination of aircraft speed and runway independence.”
ChargePoint announced today the first large-scale deployment of its all-new Express Plus Power Link 2000 DC fast charging platform, which is capable of delivering charging speeds up to 500 kilowatts.
The hardware and associated software of the Power Link system debuted today at the all-new Mercedes-Benz HPC NA fast charging network, which due to the high power output, is being called “the fastest public charging network in North America.”
Let’s recall that the Mercedes-Benz HPC NA will be a premium DC fast charging network for all EVs, consisting of up to 400 sites (and over 2,500 chargers) by 2030. Some of the stations will be installed at Simon Property Group’s locations (at least 55) and Buc-ee’s chain of travel centers (about 30 sites).
Lithium metal, chosen for battery anodes due to its superior energy density compared to other materials, is a smart choice. Yet, challenges arise at the interface between the electrode and the electrolyte, presenting opportunities for enhancement to achieve safer and more efficient performance in future applications.
Researchers from Tsinghua University are keen on replacing the graphite anode with a lithium metal anode to construct a battery system with higher energy density. However, the Li metal anode is unstable and readily reacts with electrolytes to form a solid-electrolyte interphase (SEI). Unfortunately, the natural SEI is brittle and fragile, resulting in poor lifespan and performance.
Here, the researchers have looked into a substitute for natural SEI, which could effectively mitigate the side reactions within the battery system. The answer is ASEI: artificial solid electrolyte interphase. ASEI corrects some of the issues plaguing the bare lithium metal anode to make a safer, more reliable, and even more powerful source of power that can be used with more confidence in electric vehicles and other similar applications.
