Metals aren’t known to “heal” themselves on their own; once they break, it’s assumed the materials remain broken unless outside forces reform them. But new research into metallic properties indicates this isn’t always the case. In fact, some metals appear to naturally mend of their own accord—a discovery that could one day change engineering designs here on Earth and beyond.

According to a study published last week in Nature, materials scientists from Sandia National Laboratories in Albuquerque, New Mexico, and Texas A&M University discovered at least some metals—in this case copper and platinum—can “undergo intrinsic self-healing.” As Live Science recently noted, the team’s observations came completely by accident while observing the two materials at a nanoscale level.

An international team of space scientists has found evidence that hydrogen peroxide on Ganymede, Jupiter’s largest moon, exists only on its higher latitudes. For their research, reported in the journal Science Advances, the group studied data from the James Webb Space Telescope (JWST).

For many years, researchers theorized that hydrogen peroxide existed on Ganymede, but it took a prior team studying data from the JWST to find it. In this new effort, the research team analyzed new data sent back by the telescope to learn more about the surface of the moon and its hydrogen peroxide.

Ganymede is the largest moon in the solar system, but it has not received nearly the attention given to another of Jupiter’s moons, Europa, whose features and characteristics make it far more likely to have harbored life at some point in time. But prior research has shown that the influence of Jupiter’s magnetic field on many of its moons could indicate a strong probability of hydrogen peroxide on Ganymede. This is because of its likely impact on the water-ice irradiation process on its surface.

SpaceX has shared a stunning shot (above) of its next-generation Super Heavy booster on the launchpad.

The image shows the most powerful rocket in the world under a starlit sky at SpaceX’s Starbase site in Boca Chica, Texas. At the bottom of the booster, we can see some of the Super Heavy’s 33 Raptor engines that will blast the rocket to orbit.

With the launch of the Mac Pro and M2 Ultra chip at WWDC in June, all eyes are now on the next phase of Apple silicon and the highly anticipated M3 processor. And according to a new report, every Mac in Apple’s lineup will be getting in on the action.

In his latest Power On newsletter, Mark Gurman reports that an M3 Mac mini is “a sure thing,” as is a new MacBook Pro with M3 Pro and M3 Max processors. The Mac mini has previously gone years between updates, so it’s notable that Apple plans to refresh it so soon after the release of the M2 model.

Gurman previously reported that Apple is planning to launch the M3 chip alongside three new Macs: the 13-inch MacBook Air, the 13-inch MacBook Pro, and the 24-inch iMac. We can also expect to see an M3 version of the 15-inch Air, if not at the same time then within a few months of the announcement.

An anomaly known as the geoid low has long puzzled geologists. One team has found what it believes is a credible explanation, and it’s coming from deep inside Earth.

Resistance to current cancer treatments is an important problem that arises through various mechanisms, but one that stands out involves an overexpression of several factors associated with DNA repair. To counteract this type of resistance, different drugs have been developed to affect one or more DNA repair pathways, therefore, to test different compounds of natural origin that have been shown to induce cell death in cancer cells is paramount. Since natural compounds target components of the DNA repair pathways, they have been shown to promote cancer cells to be resensitized to current treatments. For this and other reasons, natural compounds have aroused great curiosity and several research projects are being developed around the world to establish combined treatments between them and radio or chemotherapy. In this work, we summarize the effects of different natural compounds on the DNA repair mechanisms of cancer cells and emphasize their possible application to re-sensitize these cells.

Day by day we are exposed to chemical carcinogens in the environment, ultraviolet (UV) radiation, ionizing radiation, and also those substances produced in our body during cellular metabolism that attack and produce a variety of DNA injuries. Each lesion favors the development of alterations in DNA and chromosomes, which favors oncogenic transformation and tumor progression. In order to reduce the number of changes in the genome and its instability, cells have several pathways of response to damage and DNA repair proteins that eliminate these lesions. DNA adducts, such as those created by alkylating agents, can be cleaved and repaired by base excision repair (BER) or by nucleotide excision repair (NER), depending on whether it is necessary to remove only a nitrogenous base or a nucleotide. Also, O-6-methylguanine-DNA methyltransferase (MGMT), an alkyltransferase, eliminates alkylations.
