Should scientists be allowed to edit the genes of wild animals? Top conservation groups just voted yes

She said that the new framework represents a “landmark step,” and that the measure could allow conservationists to consider new ways to address the risks of climate change or test new methods of suppressing disease.

The IUCN — a large group of conservation organizations, governments and Indigenous groups with more than 1,400 members from about 160 countries — meets once every four years. It is the world’s largest network of environmental groups and the authority behind the red list, which tracks threatened species and global biodiversity.

Tyk2 Targeting in Immune-Mediated Inflammatory Diseases

The Janus kinase (Jak)/signal transducer and activating protein (STAT) pathways mediate the intracellular signaling of cytokines in a wide spectrum of cellular processes. They participate in physiologic and inflammatory cascades and have become a major focus of research, yielding novel therapies for immune-mediated inflammatory diseases (IMID). Genetic linkage has related dysfunction of Tyrosine kinase 2 (Tyk2)—the first member of the Jak family that was described—to protection from psoriasis. Furthermore, Tyk2 dysfunction has been related to IMID prevention, without increasing the risk of serious infections; thus, Tyk2 inhibition has been established as a promising therapeutic target, with multiple Tyk2 inhibitors under development.

What happened to those ‘little red dots’ Webb observed?

When the James Webb Space Telescope (JWST) began operations, one of its earliest surveys was of galaxies that existed during the very early universe. In December 2022, these observations revealed multiple objects that appeared as “little red dots” (LRDs), fueling speculation as to what they might be. While the current consensus is that these objects are compact, early galaxies, there is still debate over their composition and what makes them so red. On the one hand, there is the “stellar-only” hypothesis, which states that LRDs are red because they are packed with stars and dust.

This means that they could be similar to “dusty galaxies” that are observed in the universe today. On the other hand, there is the” MBH and galaxy” theory, which posits that LRDs are early examples of active galactic nuclei (AGNs) that exist throughout the universe in modern times. Each model has significant implications for how these galaxies subsequently evolved to become the types of galaxies observed more recently.

In a recent paper posted to the arXiv preprint server, an international team of astronomers considered the different scenarios. They concluded that LRDs began as “stellar only” galaxies that eventually formed the seeds of the supermassive black holes (SMBHs) at the center of galaxies today.

The Impact of Physicochemical Conditions on Lactic Acid Bacteria Survival in Food Products

Lactic acid bacteria (LAB), due to their many advantageous features, have been utilized in food manufacturing for centuries. Spontaneous fermentation, in which LAB play a fundamental role, is one of the oldest methods of food preservation. LAB survival and viability in various food products are of great importance. During technological processes, external physicochemical stressors appear often in combinations. To ensure the survival of LAB, adjustment of optimal physicochemical conditions should be considered. LAB strains should be carefully selected for particular food matrices and the technological processes involved. The LAB’s robustness to different environmental stressors includes different defense mechanisms against stress, including the phenomenon of adaptation, and cross-protection.

Blood test can detect more than 50 kinds of cancer, new study suggests

Made by U.S. pharmaceutical company Grail, the Galleri test aims to find fragments of DNA in a person’s blood that can indicate the presence of a cancerous tumor. Among the cancers that the test can detect, many have no current screening programs.

The PATHFINDER 2 study included more than 36,000 people aged 50 and older who had no cancer symptoms. In participants who were followed for more than a year, the test caught some 40.4% of cancer cases. For those who got a positive result on the Galleri test, 61.6% of them went on to be diagnosed with cancer—an improvement over previous trials of the test.

The results were presented on Saturday at the European Society for Medical Oncology meeting in Berlin, and have yet to be published in a peer-reviewed journal.

Cryosphere Chat ft. Emil Kendziorra — Tales from Biostasis 2025, Our Near Death Experiences

The gang catches up with Emil Kendziorra after the Biostasis 2025 conference at the European Biostasis Foundation. Watch it on YouTube here. Topics covered include:

• How to get a Tomorrow Bio ambulance in your hometown.
• Tomorrow Bio’s plan to collect brain samples to check ultra-structure preservation in its cryonics patients — and how it will respond to what it finds.
• What’s new and what’s next for Tomorrow Bio.
• Our near death experiences.

Scientists create a metal that does not break, rust, or melt

A new alloy made from chromium, molybdenum, and silicon – three metals known for strength, heat tolerance, and stability – breaks expectations by staying tough at room temperature while resisting oxidation even under extreme heat.

The study reports room temperature ductility, oxidation resistance in air to 1,100 C, and a melting point near 2,000 C.

A Tiny Peptide Can Freeze Parkinson’s Proteins Before They Turn Toxic

As Parkinson’s disease progresses, harmful protein clumps build up in the brain, blocking communications between neurons and killing them off – but what if we could prevent these clusters from forming?

Researchers led by a team from the University of Bath in the UK have achieved just that in a basic worm model of Parkinson’s. They engineered a peptide, a small amino acid chain, to essentially keep a protein called alpha-synuclein locked in its healthy shape. This prevented the misfolding that leads to clumps.

The potential treatment checks several important boxes: it’s durable, and it can survive inside cells without causing any toxic side effects.
