Artificial intelligence improves personalized cancer treatment

Computers and Math from Science Daily Feed - Thu, 01/30/2025 - 10:56am
Personalized medicine aims to tailor treatments to individual patients. Until now, this has been done using a small number of parameters to predict the course of a disease. However, these few parameters are often not enough to understand the complexity of diseases such as cancer. A team of researchers has developed a new approach to this problem using artificial intelligence (AI).

New insights on radical trapping in 12-phosphatetraphene uncovered

Matter and energy from Science Daily Feed - Thu, 01/30/2025 - 10:56am
Muon spin rotation ( SR) spectroscopy is a powerful technique used to study the behavior of materials at the atomic level. In this study, researchers employed SR to examine phosphorus-containing 12-phosphatetraphene 1 molecule (muoniated radical). Their findings provide new insights into the radical's structure and behavior, advancing understanding of reactive species and radical behavior.

Your fridge uses tech from the 50's, but scientists have an update

Matter and energy from Science Daily Feed - Thu, 01/30/2025 - 10:55am
Researchers report that a more efficient and environmentally friendly form of refrigeration might be on the horizon. The new technology is based on thermogalvanic cells that produce a cooling effect by way of a reversible electrochemical reaction. Thermogalvanic refrigeration is cheaper and more environmentally friendly than other cooling methods because it requires a far lower energy input, and its scalability means that it could be used for various applications -- from wearable cooling devices to industrial-grade scenarios.

Generating electricity from tacky tape

Matter and energy from Science Daily Feed - Thu, 01/30/2025 - 10:54am
Zaps of static electricity might be a wintertime annoyance, but to certain scientists, they represent an untapped source of energy. Using a device called a triboelectric nanogenerator (TENG), mechanical energy can be converted into electrical energy using triboelectric effect static. Many TENGs contain expensive, specially fabricated materials, but one team has instead used inexpensive store-bought tape, plastic and aluminum metal.

Readers’ wildlife photos

Why Evolution is True Feed - Thu, 01/30/2025 - 6:15am

Today’s photos come from Phil Frymire, who sends us birds photographed in South Africa. Phil’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

Moving on from my previous submissions of mammals, here is a selection of birds from an August trip to South Africa. Lilac-breasted rollers are unforgettable, but I am a bit fuzzy on some of the other identifications. I forgot some of them and had to look them up online. Hopefully readers can make corrections if any errors remain.

Red-crested korhaan (Lophotis ruficrista):

Magpie shrike (Urolestes melanoleucus)

A pair of African fish eagles (Haliaeetus vocifer):

White-backed vulture (Gyps africanus), waiting for lions to leave a giraffe kill:

This is a poor photo of a black-headed oriole (Oriolus larvatus). This bird is a beautiful bright yellow. This was the only one we saw and it was quite skittish:

African green pigeon (Treron calvus):

White-fronted bee-eater (Merops bullockoides), perched on some elephant dung:

A gaggle of Egyptian geese (Alopochen aegyptiaca):

Hooded vulture (Necrosyrtes monachus), waiting for lions to abandon a buffalo kill:

Crested barbet (Trachyphonus vaillantii):

Helmeted guinea fowl (Numisa meleagris):

This is a saddle-billed stork (Ephippiorhynchus senegalensis). The first time I saw one I thought it must have an injury on its breast. No, the bare red spot is typical for the species:

Last, but certainly not least, my favorite bird seen on the trip, three lilac-breasted rollers (Coracias caudatus) [: This is my favorite African bird, too!]

Incorruptible Skepticism

neurologicablog Feed - Thu, 01/30/2025 - 4:50am

Everything, apparently, has a second life on TikTok. At least this keeps us skeptics busy – we have to redebunk everything we have debunked over the last century because it is popping up again on social media, confusing and misinforming another generation. This video is a great example – a short video discussing the “incorruptibility’ of St. Teresa of Avila. This is mainly a Catholic thing (but also the Eastern Orthodox Church) – the notion that the bodies of saints do not decompose, but remain in a pristine state after death, by divine intervention. This is considered a miracle, and for a time was a criterion for sainthood.

The video features Carlos Eire, a Yale professor of history focusing on medieval religious history. You may notice that the video does not include any shots of the actual body of St. Teresa. I could not find any online. Her body is not on display like some incorruptibles, but has been exhumed in 1914 and again recently. So we only have the reports of the examiners. This is where much of the confusion is generated – the church defines incorruptible very differently than the believers who then misrepresent the actual evidence. Essentially, if the soft tissues are preserved in any way (so the corpse has not completely skeletonized) and remains somewhat flexible, that’s good enough.

The case of Teresa is typical – one of the recent examiners said, “There is no color, there is no skin color, because the skin is mummified, but you can see it, especially the middle of the face.” So the body is mummified and you can only partly make out the face. That is probably not what most believers imagine when the think of miraculous incorruptibility.

This is the same story over and over – first hand accounts of actual examiners describe a desiccated corpse, in some state of mummification. Whenever they are put on display, that is exactly what you see. Sometimes body parts (like feet or hands) are cut off and preserved separately as relics. Often a wax or metal mask is placed over the face because the appearance may be upsetting to some of the public. The wax masks can be made to look very lifelike, and some viewers may think they are looking at the actual corpse. But the narrative among believers is often very different.

It has also been found that there are many very natural factors that correlate with the state of the allegedly incorruptible bodies. A team of researchers from the University of Pisa explored the microenvironments of the tombs:

“They discovered that small differences in temperature, moisture, and construction techniques lead to some tombs producing naturally preserved bodies while others in the same church didn’t. Now you can debate God’s role in choosing which bodies went into which tombs before these differences were known, but I’m going to stick with the corpses. Once the incorrupt bodies were removed from these climates or if the climates changed, they deteriorated.”

The condition of the bodies seems to be an effect of the environment, not the saintliness of the person in life.

It is also not a secret – though not advertised by promoters of miraculous incorruptibility – that the bodies are often treated in order to preserve them. This goes beyond controlling the environment. Some corpses are treated with acid as a preservative, or oils or sealed with wax.

When you examine each case in detail, or the phenomenon as a whole, what you find is completely consistent with what naturally happens to bodies after death. Most decay completely to skeletons. However, in the right environment, some may be naturally mummified and may partly or completely not go through putrefaction. But if their environment is changed they may then proceed to full decay. And bodies are often treated to help preserve them. There is simply no need for anything miraculous to explain any of these cases.

There is also a good rule of thumb for any such miraculous or supernatural claim – if there were actually cases of supernatural preservation, we would all have seen it. This would be huge news, and you would not have to travel to some church in Italy to get a few of an encased corpse covered by a wax mask.

As a side note, and at the risk of sounding irreverent, I wonder if any maker of a zombie film considered having the corpse of an incorruptible animate. If done well, that could be a truly horrific scene.
