Cells of the future: A key to reprogramming cell identities

Science Daily: Pharmacology News

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.

Botulism: Symptoms, Diagnosis, Treatment, History, and Epidemiology

Gideon

Did you know that less than one gram of botulism toxin can wipe out all of humankind? While the botulism toxin is one of the deadliest toxins known, a very diluted version, known as Botox, is used routinely as a chemical ‘fountain of youth.’ While botulism poisoning doesn’t spread from person to person, outbreaks do occur and, in severe cases, lead to hospitalization and even death.

Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research

Science Daily: Pharmacology News

Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.

Why we need a new measure of maternal health: the “lifetime risk of maternal near miss”

International Journal of Epidemiology Blog

Ursula Gazeley According to the most recent data from the World Health Organization , the lifetime risk of maternal death for a girl in Chad is a staggering 1 in 15, compared with 1 in 43,000 in Norway. This means that a girl in Chad has an almost 3000 times greater risk of dying from a maternal cause during her reproductive lifetime than a girl in Norway.

Evaluating the truthfulness of fake news through online searches increases the chances of believing misinformation

Science Daily: Pharmacology News

Conventional wisdom suggests that searching online to evaluate the veracity of misinformation would reduce belief in it. But a new study by a team of researchers shows the opposite occurs: Searching to evaluate the truthfulness of false news articles actually increases the probability of believing misinformation.

Meet 'Coscientist,' your AI lab partner

Science Daily: Pharmacology News

An artificial intelligence-driven system has autonomously learned about certain Nobel Prize-winning chemical reactions and designed a successful laboratory procedure to make them. The AI did so in just a few minutes and correctly on its first attempt. According to the authors, this is the first time that a non-organic intelligence planned, designed and executed this complex reaction that was invented by humans.

Common insect species are suffering the biggest losses

Science Daily: Pharmacology News

Insect decline is being driven by losses among the locally more common species, according to a new study. The meta-analysis of 923 locations around the world notes two significant trends: 1) the species with the most individuals (the highest abundance) are disproportionately decreasing in number, and 2) no other species have increased to the high numbers previously seen.
