‘Antarctica could transform from Earth’s refrigerator to a radiator’ as Earth is losing sea-ice that helps maintain balance in the planet’s temperature.

Recently, satellite data depicted that the sea ice in and around the Antarctica region reached record-low levels during winter.

This is a concerning development, given Antarctica’s historical resistance to global warming, BBC reported on Sunday (September 17). Scientists caution against unstable consequences of climate change in the polar regions.

Living things act with purpose. But where does purpose come from? How do humans make sense of their relation to the world and realize their ability to effect change? These fundamental questions of “agency”—acting with purpose—have perplexed some of the greatest minds in history including Sir Isaac Newton, Charles Darwin, Erwin Schrödinger and Niels Bohr.

A Florida Atlantic University (FAU) study reveals groundbreaking insight into the origins of agency using an unusual and largely untapped source— human babies. Since goal-directed action appears in the first months of human life, the FAU research team used young infants as a test field to understand how spontaneous movement transforms into purposeful action.

We’ve highlighted a lot of bright innovators over the years, usually before they become household names. Sergey Brin of Google was on the list in 2002. JB Straubel was honored in 2008 when he was CTO of Tesla. That year also saw Andrew Ng make the list (he’s one of the biggest names in AI right now, and he came back this year to write an intro essay, which I highly recommend.)

As I looked through the folks who made the list in the climate and energy category in 2023, I noticed a few trends. In particular, there was a concentration in two areas I think a lot about: batteries and fuels. So let’s take a closer look at a few of this year’s innovators and consider what their work could mean for the future of climate action.

The problem of space debris would worsen even if we sent nothing else into orbit.

ESA’s Space Environment report 2023 was published last August and highlighted a key problem: space debris. “Our planet is surrounded by spacecraft carrying out important work to study our changing climate, deliver global communication and navigation services and help us answer important scientific questions,” noted the report.

“But some of their orbits are getting crowded and increasingly churning with deadly, fast-moving pieces of defunct satellites and rockets that threaten our future in space.”

“Lightning” system connects photons to the electronic components of computers using a novel abstraction, creating the first photonic computing prototype to serve real-time machine-learning inference requests.

Computing is at an inflection point. Moore’s Law, which predicts that the number of transistors on an electronic chip will double each year, is slowing down due to the physical limits of fitting more transistors on affordable microchips. These increases in computer power are slowing down as the demand grows for high-performance computers that can support increasingly complex artificial intelligence models. This inconvenience has led engineers to explore new methods for expanding the computational capabilities of their machines, but a solution remains unclear.

Potential of Photonic Computing.

Apple unveiled its new iPhone lineup on Tuesday, with its Lightning charger ports replaced on the newest models by a universal charger after a tussle with the European Union.

The European bloc is insisting that all phones and other small devices must be compatible with the USB-C charging cables from the end of next year, a move it says will reduce waste and save money for consumers.

The firm had long argued that its cable was more secure than USB-C chargers, which are already deployed by Apple on other devices and widely used by rivals including the world’s biggest smartphone maker Samsung.

Hurricane Lee is bringing dangerous rip currents and huge waves to the East Coast.

Reconstructed ancient plant protein should help crops counter the ongoing rise in global temperatures, says Cornell University plant biologist.

MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances.

This technique, which the researchers began developing several years ago, uses about one-millionth the power that existing underwater communication methods use. By expanding their battery-free system’s communication range, the researchers have made the technology more feasible for applications such as aquaculture, coastal hurricane prediction, and climate change modeling.

“What started as a very exciting intellectual idea a few years ago—underwater communication with a million times lower power—is now practical and realistic. There are still a few interesting technical challenges to address, but there is a clear path from where we are now to deployment,” says Fadel Adib, associate professor in the Department of Electrical Engineering and Computer Science and director of the Signal Kinetics group in the MIT Media Lab.
