James Webb Unveils a Mysterious Planet Unlike Anything in Our Solar System

The James Webb Space Telescope.

The James Webb Space Telescope (JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope. It covers longer wavelengths of light, with greatly improved sensitivity, allowing it to see inside dust clouds where stars and planetary systems are forming today as well as looking further back in time to observe the first galaxies that formed in the early universe.

Newly discovered group hosts two optically dark star-forming galaxies

An international team of astronomers reports the discovery of a new compact galaxy group using the Atacama Large Millimeter/submillimeter Array (ALMA). The new group, designated CGG-z4, hosts two optically dark star-forming galaxies. The finding was detailed in a research paper published Jan. 9 on the pre-print server arXiv.

Galaxy groups are the smallest aggregates of galaxies, typically containing up to 50 members. For astronomers, overdense structures like protoclusters or are prime targets to help them investigate the growth of massive galaxies.

Recent observations performed by a group of astronomers led by Malte Brinch of the Technical University of Denmark, have uncovered the presence of a new galaxy group. They identified the new group with ALMA in the Cosmic Evolution Survey (COSMOS) field.

Stronger, Smarter, and More Selective: Armor-Like MOF Membrane Sets New Standard for Chemical Separations

Posted by in categories: chemistry, energy

Researchers developed a durable, bioinspired ZIF-67 MOF membrane that efficiently separates propylene from propane, offering high performance, long-term stability, and industrial scalability.

Polymer-grade propylene (99.5%) is a vital raw material in the chemical industry. Its production inevitably generates propane as a byproduct in the product stream. A critical step in producing polymer-grade propylene is the separation of propylene from propane—a challenging and energy-intensive process due to the molecules’ nearly identical physical and chemical properties.

Molecular sieve membranes offer an energy-efficient and effective solution for this separation. Metal-organic frameworks (MOFs.

In Disney’s ‘Moana,’ the Characters Navigate using the Stars—an Astronomer explains how these methods work

Posted by in category: education

If you have visited an island like one of the Hawaiian Islands, Tahiti or Easter Island, also known as Rapa Nui, you may have noticed how small these land masses appear against the vast Pacific Ocean. If you’re on Hawaii, the nearest island to you is more than 1,000 miles (1,600 kilometers) away, and the coast of the continental United States is more than 2,000 miles (3,200 kilometers) away. To say these islands are secluded is an understatement.

For me, watching the movie “Moana” in 2016 was eye-opening. I knew that Polynesian people traveled between a number of Pacific islands, but seeing Moana set sail on a canoe made me realize exactly how small those boats are compared with what must have seemed like an endless ocean. Yet our fictional hero went on this journey anyway, like the countless real-life Polynesian voyagers upon which she is based.

As an astronomer, I have been teaching college students and visitors to our planetarium how to find stars in our sky for more than 20 years. As part of teaching appreciation for the beauty of the sky and the stars, I want to help people understand that if you know the stars well, you can never get lost.

Eating Red Meat may Increase your Risk of Type 2 Diabetes—not a lot of people know that

Posted by in category: biotech/medical

Red meat has been a part of diets worldwide since early man. It is an excellent source of protein, vitamins (such as B vitamins) and minerals (such as iron and zinc). However, red meat has long been associated with increasing the risk of heart disease, cancer and early death. What may not be so well known is the link between red meat consumption and type 2 diabetes.

A paper published in The Lancet in September 2024 highlighted this link to type 2 diabetes using data from the Americas, the Mediterranean, Europe, south-east Asia and the Western Pacific (20 countries included).

This recent study, with nearly 2 million participants, found that high consumption of unprocessed red meat, such as beef, lamb and pork, and processed meat, such as bacon, salami and chorizo, increased the incidence of type 2 diabetes.

Synthesis of pillar-layered metal–organic frameworks with variable backbones through sequence control

Posted by in category: materials

Zoom

The tailoring of reticular materials is key for enhancing the complexity and diversity of their structure and function. Now, a series of isomeric pillar-layered metal–organic frameworks with tunable topologies have been prepared through altering the layer stacking, which enables variability on the backbone structure, pillar spatial arrangements and pore structure.

Brain-controlled interface experiment provides empirical support for one-way neural activity paths

Posted by in categories: physics, robotics/AI

Neural network models that are able to make decisions or store memories have long captured scientists’ imaginations. In these models, a hallmark of the computation being performed by the network is the presence of stereotyped sequences of activity, akin to one-way paths. This idea was pioneered by John Hopfield, who was notably co-awarded the 2024 Nobel Prize in Physics. Whether one-way activity paths are used in the brain, however, has been unknown.

A collaborative team of researchers from Carnegie Mellon University and the University of Pittsburgh designed a clever experiment to perform a causal test of this question using a (BCI). Their findings provide empirical support of one-way activity paths in the brain and the computational principles long hypothesized by neural network models.
