The James Webb Space Telescope has spotted six likely rogue worlds — objects with planet-like masses but untethered from any star’s gravity — including the lightest ever identified with a dusty disk around it.

The elusive objects offer new evidence that the same cosmic processes that give birth to stars may also play a common role in making objects only slightly bigger than Jupiter.

The Overview Effect, the profound shift in human perception that occurs when one sees Earth from the outside, has the power to foster peace and global brotherhood. This underscores the urgent need for an increasing number of people, not just machines, to venture into space.

The concept encapsulated in the title above is the culmination of a two-day discussion held in New York under the auspices of the Summit of the Future. The Space Renaissance International and its 102 allied organizations, the Space 18th SDG Coalition, played a pivotal role in organizing these two events.

At the International Conference on High-Energy Physics in Prague in July, the LHCb collaboration presented an updated measurement of the weak mixing angle using the data collected at the experiment between 2016 and 2018. The measurement benefits from the unique forward coverage of the LHCb detector.

The success of electroweak theory in describing a wide range of measurements at different experiments is one of the crowning achievements of the Standard Model ℠ of particle physics. It explains electroweak phenomena using a small number of free parameters, allowing precise measurements of different quantities to be compared to each other. This facilitates powerful indirect searches for beyond-the-SM physics. Discrepancies between measurements might imply that new physics influences one process but not another, and global analyses of high-precision electroweak measurements are sensitive to the presence of new particles at multi-TeV scales. In 2022 the entire field was excited by a measurement of the W-boson mass that is significantly larger than the value predicted within these global analyses by the CDF collaboration, heightening interest in electroweak measurements.

The weak mixing angle is at the centre of electroweak physics. It describes the mixing of the U and SU fields, determines couplings of the Z boson, and can also be directly related to the ratio of the W and Z boson masses. Excitingly, the two most precise measurements to date, from LEP and SLD, are in significant tension. This raises the prospect of non-SM particles potentially influencing one of these measurements, since the weak mixing angle, as a fundamental parameter of nature, should otherwise be the same no matter how it is measured. There is therefore a major programme measuring the weak mixing angle at hadron colliders, with important contributions from CDF, D 0, ATLAS, CMS and LHCb.

While most of us are still struggling to find SSDs with greater capacities than 4TB, Samsung is working on creating the world’s first petabyte SSD. At least, that’s their plan. Last year, reports suggested that the company was about a decade away. Now, they seem much closer.

As the world’s largest manufacturer of 3D NAND storage, they’re certainly one of the most likely to do it. Samsung has revealed more information about its planes, and how it’s working to get to that 1,000-layer NAND required for such high capacities.

Samsung has long been a leader in large capacity solid state drives. And while they’re not readily available to the average consumer due to their (still) prohibitively expensive prices, Samsung announced a 16TB SSD way back in 2015.

GC Therapeutics’ plug-and-play stem cell programming platform aims to reduce cell therapy development time by up to 100 times.

Cell therapies have revolutionized the treatment of certain disease areas; however, challenges in scaling these therapies…

Cell therapy startup GC Therapeutics (GCTx) has emerged from the lab of renowned geneticist George Church, securing a $65 million Series A funding round that brings the total raised by the company to a cool $75 million. The company is on a mission to enable the next generation of cell therapies through its proprietary TFome platform, which GCTx claims is the first plug-and-play induced pluripotent stem cell (iPSC) cellular programming platform.

KINGSTON, N.Y. (AP) — On a tributary of the Hudson River, a tugboat powered by ammonia eased away from the shipyard dock and sailed for the first time to show how the maritime industry can slash planet-warming carbon dioxide emissions.

The tugboat used to run on diesel fuel. The New York-based startup company Amogy bought the 67-year-old ship to switch it to cleanly-made ammonia, a new, carbon-free fuel.

The tugboat’s first sail on Sunday night is a milestone in a race to develop zero-emissions propulsion using renewable fuel. Emissions from shipping have increased over the last decade — to about 3% of the global total according to the United Nations — as vessels have gotten much bigger, delivering more cargo per trip and using immense amounts of fuel oil.

A neutron star is the remnant of a massive star (bigger than 10 Suns) that has run out of fuel, collapsed, exploded, and collapsed some more. Its protons and electrons have fused together to create neutrons under the pressure of the collapse. The only thing keeping the neutrons from collapsing further is “neutron degeneracy pressure,” which prevents two neutrons from being in the same place at the same time.

Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun’s mass. But all that matter has been compressed to an object about 10 miles (16 kilometers) across. A normal star of that mass would be more than 1 million miles (1.6 million km) across.

A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) — the weight of an old laptop. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) — the weight of Mount Everest. So while you could lift a spoonful of Sun, you can’t lift a spoonful of neutron star.
