Matter 1.3 Specification Adds Energy Reporting, Electric Vehicle Charging, Water Management Support and More

[ad_1]

The Connectivity Standards Alliance (CSA) today announced the debut of a new Matter 1.3 specification that’s available for device makers and platforms. Matter is a smart home protocol that allows smart devices to work across multiple platforms, including HomeKit.

matter iot standard
Matter 1.3 adds support for a range of new device types and features, including water management devices, electric vehicle chargers, kitchen and laundry appliances, and TVs.

For smart plugs and other devices, the update includes energy management reporting, allowing users to see actual and estimated measurements of power, voltage, and current, both in-real time and over time. EV Charging manufacturers are able to include Matter-based features such as manually starting and stopping charging, adjusting charging rate, and optimizing charging times.

Water management devices like leak and freeze detectors, rain sensors, and controllable water valves are supported in Matter 1.3, as are several new appliance types including microwave ovens, ovens, cooktops, extractor hoods, and dryers.

For TVs, Matter 1.3 improves casting initialization and search, plus it adds support for push messages and dialog for ambient experiences, expanded interactivity for TV apps, and better interaction with other home devices.

Scenes are supported with the new specification, allowing product makers and platforms to set, read, and activate scenes on devices. Scenes for Matter work like ‌HomeKit‌ scenes, letting users set a desired state for rooms and devices with one command. Matter controllers are also now able to batch multiple commands into a single message when communicating with Matter devices for less delay between command execution.

Matter 1.3 devices and improvements will likely be available on the market later this year, with more information available on the CSA website.

Dark energy is tearing the Universe apart. What if the force is weakening?

[ad_1]

The fate of the Universe might not be as dark and empty as cosmologists have long suspected. That’s one potential implication emerging from an innovative project that has produced some of the biggest maps ever made of the Universe.

At a meeting of the American Physical Society in Sacramento, California, in early April, researchers released initial results from the Dark Energy Spectroscopic Instrument (DESI), based at the Kitt Peak National Observatory near Tucson, Arizona. DESI started mapping the Universe in 3D in 2020 and was designed to measure the elusive force, known as dark energy, that is pushing galaxies apart.

The surprising early results suggest that dark energy could be weakening over time.

“That’s really a hint that something could be happening,” says cosmologist Nathalie Palanque-Delabrouille at Lawrence Berkeley National Laboratory in California, who is DESI’s spokesperson.

Although the study was based on only the first of the five years planned for data collection, it is already one of the largest maps ever made of the Universe, and it reveals the effects of dark energy across an unprecedented 11 billion years of cosmic history (DESI collaboration. Preprint at arXiv https://doi.org/mtqw; 2024).

If confirmed, the hints that dark energy might be weakening would bring the first substantial change in decades to the generally accepted theoretical model of the Universe. And if dark energy is not constant, that would hold implications for theories of how the Universe has evolved and for what its future might hold.

But researchers say that the evidence for changes in dark energy is still very uncertain. That was the overwhelming sentiment at a gathering of cosmologists on 15–16 April at the Royal Society in London. The standard cosmological model remains strong, most cosmologists agree — and has been working better and better as the years go by.

Wendy Freedman, an astronomer at the University of Chicago in Illinois, calls the hints of a weakening “tantalizing”, but says it will require a lot more data to see if they pan out. “Time will tell if they stand the test of time.”

Opposites attract

At the largest scales, the cosmos is ruled by gravity, and Einstein’s general theory of relativity allows for gravity to be repulsive as well as attractive. Whereas ordinary forms of energy — which includes the mass of matter — result in an attractive force, general relativity also predicts that some more-exotic forms of energy could produce repulsive gravity.

Dark energy was discovered in 1998, when two teams of astronomers used supernova explosions in distant galaxies to measure how the rate of cosmic expansion has changed. Their results indicated that the rate has accelerated over time, pushed by some unseen repulsive force that would later be dubbed dark energy. The name was intended to echo the equally mysterious entity known as dark matter — which is invisible but can be measured by its gravitational influence on galaxies.

The 1998 data that led to the discovery of dark energy had large error bars, and they were consistent with the simplest possible assumption: that dark energy is spread uniformly across space, earning it the name cosmological constant, or Λ. A consensus emerged around a theory called Λ cold dark matter (ΛCDM), in which cosmic history is largely the result of a struggle between the pull of dark matter and the push of dark energy.

Save for small deviations that remain unexplained, all of the evidence cosmologists have collected so far has strengthened this ΛCDM model. The gold standard was set in 2013 by the Planck space mission of the European Space Agency (ESA), which mapped the relic radiation from the early Universe, called the cosmic microwave background. The data from that mission are in “exquisite” agreement with the model, says senior Planck researcher George Efstathiou, a cosmologist at the University of Cambridge, UK. The current Universe, Planck found, is about 70% dark energy, 25% dark matter and 5% ordinary matter — the stuff of stars, planets and people.

Many fates

The standard assumption of ΛCDM is that the expansion of the Universe will continue to accelerate, and that most galaxies would ultimately disappear from view. But theorists have developed hundreds of other models of dark energy; many posit that dark energy could be getting slowly diluted, and the Universe’s expansion will start to slow down. Another possibility is that dark energy is getting stronger and will ultimately rip galaxies apart.

For a long time, the hints from observations were too vague to answer even the most basic questions about dark energy: exactly how strong is it, and is it constant or slowly changing? DESI is the first in a new generation of experiments aimed at providing some answers. Others include ESA’s Euclid mission, which launched into space last year; the massive, 8-metre telescope of the Vera C. Rubin Observatory nearing completion in the Chilean Andes; and NASA’s Nancy Grace Roman Space Telescope, scheduled to launch in 2027. Another telescope, called eROSITA, part of a Russian–German space mission, has mapped the Universe in the X-ray spectrum.

“There’s a whole slew of projects that are about to start taking data or have just started,” Palanque-Delabrouille said at the Royal Society meeting. “This is really unique in the history of cosmology.”

All of these efforts rely on mapping the distribution of matter in the Universe over vast distances, which — because of the time that light takes to reach Earth — also means over vast stretches of time. DESI does not take pictures of the sky in the way that an ordinary telescope camera does, but instead collects light from selected locations in its field of view. It does so by pointing optical fibres at objects — typically galaxies or quasars — with its 5,000 robotic arms, and routing that light to sensitive spectrographs. The spectrum of each object reveals its distance, because the farther away the object is, the faster it moves away, and the more its spectrum has ‘redshifted’ towards longer wavelengths.

To reconstruct the history of cosmic expansion from its 3D data, the DESI team uses one of the most well-established techniques in cosmology. It looks at the relic of what used to be sound waves in the primordial Universe.

As space expanded and matter cooled over time, the waves became frozen in the distribution of protons and neutrons (known collectively as baryons) across the Universe. That imprint, called baryon acoustic oscillations, or BAO, is still detectable today in how galaxies are scattered across space.

The BAO features are the largest structures in the Universe. “If we could see them individually, we would see a shell,” Palanque-Delabrouille explains. “It’s like when you throw pebbles in a lake. If you throw just one pebble, you can see its waves expanding out,” she says. “If you throw too many pebbles at once, all the ripples they produce will overlap with one another.”

Immense scope

DESI doesn’t just see the BAOs in the current Universe. Its 3D map stretches back in time, and by measuring how the average size of the features has grown over time, cosmologists can reconstruct the rate of expansion — and from that, the strength of dark energy. The instrument’s results are in principle still compatible with all the options — a dark energy that is constant, weakening or even strengthening.

At the most basic level, the DESI results provide solid confirmation of the original discovery, says Ofer Lahav, a cosmologist at University College London who is part of the DESI collaboration. “To me, it’s spectacular that you can confirm that the Universe is accelerating, and more or less get the same value people have claimed 25 years ago,” he says.

“The instruments, data and measurements are spectacular,” says Marc Kamionkowski, a theoretical cosmologist at Johns Hopkins University in Baltimore, Maryland.

Kamionkowski says that he is cautious about interpreting the results as indicating that dark energy is weakening. He says that they could be an effect of the particular type of analysis the team did. Pedro Ferreira, a theoretical physicist at the University of Oxford, UK, agrees, pointing to a study he published last year with his colleague William Wolf, which called for cosmologists to change how they interpret dark-energy data (W. J. Wolf and P. G. Ferreira Phys. Rev. D 108, 103519; 2023). Ferreira adds that he is pessimistic that even the coming high-powered studies together will be able to pin down a theoretical model for dark energy.

But researchers hold out hope that the extra data will point in new directions.

The standard model was created as the simplest possible theory for the Universe, but the actual physics of its contents is probably more complicated, says Eleonora Di Valentino, a cosmologist at the University of Sheffield, UK. “I don’t believe that ΛCDM can be the final answer,” she says.

Cosmologist James Peebles — a chief architect of the standard model that helped to earn him a Nobel Prize in 2019 — agrees. “I find it very difficult to imagine that ΛCDM is the end of the story,” says Peebles, who is at Princeton University in New Jersey. “It’s too simple.”

Support communities that will lose out in the energy transition

[ad_1]

With many places around the world heavily reliant on fossil-fuel production for jobs, there is a need for more global studies to assess the impact of decarbonization on affected communities.Credit: Madeleine Jettre/Alamy

Thirty million new jobs. According to the International Energy Agency, that’s what the clean-energy sector will need by 2030 if the world follows a path towards net-zero greenhouse-gas emissions by 2050, limiting global warming to 1.5 °C above pre-industrial levels. It compares with the 13 million jobs at risk in the fossil-fuel sector under the same scenario. On the basis of the bare numbers, it’s a trade-off worth making. But every job lost affects someone, and new jobs won’t necessarily be located where the old ones are lost.

As the world transitions away from fossil fuels, communities, states and countries that rely on fossil energy could see their economies falter and their tax bases shrink. Public discontent and backlash from climate policies is increasing in the Americas, Europe and elsewhere. Political leaders are rightly moving to protect the world from the effects of global warming, but more must be done to ensure that those who depend on fossil fuels for their livelihoods are not casualties of the clean-energy transition.

The United States is showing signs of understanding the problem on, or close to, the required scale. The administration of President Joe Biden, working with Congress, has secured around US$1 trillion in climate spending for the decade to 2032. Billions of these dollars will flow to communities that are dependent on coal, oil and gas for jobs and tax revenues. The spending will cover areas such as environmental remediation and worker reskilling, as well as incentives for businesses to invest in hydrogen energy and carbon capture.

But as such programmes are rolled out, there’s an increasing need to assess whether they are achieving the desired objective of bringing about an equitable transition to clean energy. The US-based Resilient Energy Economies (REE) initiative is one project trying to do just that. With a modest sum of almost $2 million in seed money from the Bezos Earth Fund, it is seeking to better understand the economic risks and opportunities for fossil-fuel-dependent communities. Projects already funded include evaluations of recent federal programmes intended to help at-risk communities; efforts to understand the risks and opportunities of decarbonization for members of Indigenous American communities who have worked in the oil and gas industries; and schemes to assess the impact of closure or threatened closure of fossil-fuel power plants on various communities. The REE is also looking to fund new proposals. It is US-focused, but this type of research is in fact needed globally.

There is a precedent for understanding such large-scale economic transitions: researchers have previously studied the loss of industrial jobs in high-income countries as a result of the manufacturing boom in low- and middle-income countries. Work led by David Autor, an economist at the Massachusetts Institute of Technology in Cambridge, has shown how US factory closures associated with a rise in imports from China, particularly after China’s entry into the World Trade Organization in 2001, led to economic stagnation in communities across the United States. Between 1999 and 2011, the United States is estimated to have lost up to 2.4 million jobs to this ‘China shock’ (see go.nature.com/3uhk5cs). By mapping out where these jobs were lost, and comparing this information with district-by-district voting trends, the authors suggest that this shock is associated with the increased political polarization the country is seeing1.

At the same time, there’s evidence that appropriate, targeted support for those affected by the clean-energy transition could build popular support for climate action. A polling study2 published earlier this year by political scientist Alexander Gazmararian at Princeton University in New Jersey, for instance, found that most people in coal-dependent communities in the Appalachian region of the United States would be more likely to support climate policies if these were coupled with economic assistance to make the transition less painful. This also holds in Spain, according to a study by Diane Bolet at the University of Essex in Colchester, UK, and her colleagues3.

Environmental economists, pro-climate politicians and campaigners have understandably focused their research and policymaking on the positive aspects of the clean-energy transition, making the case that a green transition creates benefits such as new jobs, cleaner air and more secure food supplies. But there must also be a focus on those who will bear the economic burden of decarbonization.

At last year’s COP28 climate conference in Dubai, world leaders pledged to transition energy systems away from fossil fuels. They also committed to doing so in a “just, orderly and equitable manner”. This is not just the right thing to do; it might also be our only hope of building the viable political coalition that is needed to get the work done, for the good of people and communities everywhere.
