Shedding light on the mechanism of yeast DNA repair
2024-08-29
DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can generate double-strand breaks (DSBs) in DNA. To counteract DNA damage, cells engage in DNA repair to preserve genetic integrity and ensure cell survival as failure to repair DSBs has serious health complications like increased risk of cancer.
DSBs are repaired by two mechanisms called non-homologous end joining (NHEJ) and homologous recombination (HR). NHEJ is the predominant DNA repair mechanism in human somatic cells and is ...

Gria: An efficient deterministic concurrency control protocol
2024-08-29
The concurrency control in deterministic databases, i.e., deterministic concurrency control, ensures that each transaction batch produces a unique result. In this way, replicas can process transactions in batches without communicating with each other to ensure consistency, which is simpler and more efficient than non-deterministic databases in achieving high availability through replication.
Early deterministic concurrency control protocols, e.g. Calvin, Bohm, PWV, rely on the prior knowledge of the read-write set, which is impractical in most scenarios. The state-of-the-art Ari breaks this limitation. However, Aria has three issues. First, ...

Study reveals molecular mechanism behind MS and other autoimmune diseases
2024-08-28
New Haven, Conn. — More than two decades ago, a research team in the lab of David Hafler, a Yale researcher who at the time was at Harvard, discovered a type of T cell in humans that suppresses the immune system; they later found that these so-called regulatory T cells, when defective, are an underlying cause of autoimmune disease, specifically multiple sclerosis (MS). For many years, however, the mechanism behind this dysfunction has remained unclear.
In a new Yale-led study, a team of researchers finds that this loss of immune regulation is triggered by an increase in PRDM1-S, a protein involved in immune function, ...

Large language models can help detect social media bots — but can also make the problem worse
2024-08-28
An external study of Twitter in 2022 estimated that between a third and two thirds of accounts on the social media site were bots. And many of these automatons flooding social media are dispatched to sow political polarization, hate, misinformation, propaganda and scams. The ability to sift them out of the online crowds is vital for a safer, more humane (or at least more human) internet.
But the recent proliferation of large language models (known as "LLMs" for short), such as OpenAI’s ChatGPT and Meta’s Llama, ...
How beetle juice led to the discovery of a virus and solved the mystery of a superworm die-off
2024-08-28
Rutgers University-New Brunswick scientists have discovered a virus that caused a nationwide die-off of superworms, a common food for birds, reptiles, other pets and, more and more so, even for humans as an alternative protein source.
