Cancer’s most notorious growth protein may also be helping tumors survive chemotherapy. A protein already known for fueling cancer growth may have another troubling ability: helping damaged tumor cells repair their DNA and survive treatments designed to destroy them. Researchers at Oregon Health & Science University (OHSU) report that MYC, a protein that is overactive [...]

A new study reveals that an extremely small change in a non-coding region of DNA can dramatically alter how sex develops in mice. How much can a single letter of DNA matter? According to new research from Bar-Ilan University, one misplaced genetic “letter” can completely change the course of sexual development. In a study published [...]

A gene normally responsible for repairing DNA may have a darker side when produced in excess. Cancer treatment is increasingly moving beyond where a tumor forms and focusing instead on the genetic flaws that drive it. Now, researchers at Penn State College of Medicine have identified an unexpected DNA repair gene that could help expand [...]

Un nuovo studio condotto dal team di Elena Rostova ha rivelato che la melatonina svolge un ruolo cruciale nella protezione del DNA dei lavoratori notturni, storicamente soggetti a lesioni genetiche da stress ossidativo. La sostanza penetra nella membrana nucleare e attiva complessi enzimatici responsabili della riparazione cellulare, riducendo drasticamente la rottura dei filamenti del DNA. La scoperta dimostra che la melatonina non regola solo il sonno, ma agisce come un vero e proprio scudo epigenetico per l'organismo.

Euplotes gigatrox, a new species of ciliate collected from a seawater filtration system on the Caribbean Island of Curaçao, can transform into a cannibalistic ‘supergiant,’ raising new questions about the complexity of life at the microscopic scale.

Satan's rebellion has led humanity to believe in false origins of life, such as abiogenesis and panspermia, instead of a divine Creator. I critique the scientific community's efforts to explain life without acknowledging supernatural creation, asserting the biblical viewpoint that true life and intelligence can only stem from God.

Researchers from the University of Cambridge have created a new DNA sequencing method called Chem-map, which can detect where and how small molecule drugs interact with the targeted genome. The method enables researchers to conduct in situ mapping of small molecule-genome interactions with unprecedented precision. Chem-map was used in the study to determine the direct […]
