Most dogs love peanut butter, but the reasons for this nutty attraction range from biological to behavioral.Image credit:©iStock.com, Petra RichliWhen pet parents stroll down the store aisle looking for snacks for their canine companions, many meaty flavors greet them among the treat options. Amidst these umami-rich choices often sits another dog-favorite taste: peanut butter.While offering a pup a meat treat may feel like harkening them back to their wild ancestors who would have regularly eaten such meaty meals, why dogs love peanut butter is far less obvious. Instead, this attraction appears to be due to a blend of biology and…
There is no clear link between taking paracetamol in pregnancy and the chances of a child having autism or attention deficit/hyperactivity disorder (ADHD) later in life, an in-depth evidence review has found.1The researchers concluded that the quality of existing studies supporting such a link was “low to critically low,” adding that any apparent effect can probably be explained by family genetics and other factors.The research was fast tracked for publication by The BMJ after remarks made by US president Donald Trump in September when he advised women against taking the pain reliever during pregnancy, citing a link between the drug…

Credit: Keystone Press/AlamyHamilton (Ham) Smith co-discovered type II restriction enzymes, molecular scissors that cut DNA at precise sequence sites, which proved to be an essential tool for the emerging field of molecular biology. For this work he shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans. Smith began a second career in 1993, when he agreed to collaborate with me on sequencing the genome of the bacterium Haemophilus influenzae. On its publication in 1995, it was the first complete genome of any organism.That fortunate collaboration led to the first draft human genome sequence in…
Without changing a person’s caloric intake, intermittent fasting does not lead to measurable metabolic or cardiovascular improvements, according to new research. The study focused on time-restricted eating (TRE), a form of intermittent fasting that trims a person’s daily eating timeframe to no longer than ten hours and maintains a fasting period of at least 14 hours. Contrary to previous studies suggesting the benefits of TRE, the ChronoFast study revealed no clinically relevant changes in insulin sensitivity, blood sugar levels, blood fats, or inflammatory markers, following a two-week intervention.“Our results suggest that the health benefits observed in earlier studies were likely…
People who speak multiple languages are less likely to experience accelerated brain ageing.Credit: Prostock-Studio/GettySpeaking multiple languages could slow down brain ageing and help to prevent cognitive decline, a study of more than 80,000 people has found.The work, published in Nature Aging on 10 November1, suggests that people who are multilingual are half as likely to show signs of accelerated biological ageing than are those who speak just one language.How your brain controls ageing — and why zombie cells could be key“We wanted to address one of the most persistent gaps in ageing research, which is if multilingualism can actually delay…

For the last year, Gibson has been at the helm of AMP. In this discussion, she described activities AMP has undertaken on Capitol Hill in advocating for science funding. She stressed how the future of science and healthcare is through collaborative efforts between…
The entrance to Pfizer’s headquarters in New York. Pfizer has won the week-long bidding war for Metsera with an upwardly revised up-to-$10 billion offer matching that of rival Novo Nordisk—and more than a little help from Washington. [Pfizer] Pfizer has won the week-long bidding war for Metsera with an upwardly revised up-to-$10 billion offer matching that of rival Novo Nordisk—and more than a little help from Washington. Novo Nordisk has given up on trying to outbid Pfizer to acquire the obesity and metabolic drug developer after one-upping the pharma giant last week. Metsera joined Pfizer late Friday to announce an…
The tumor microenvironment is highly dynamic and can act in both tumor-suppressive and tumor-supportive ways.©iStock, CIPhotosThe saying goes that no man is an island, and as it turns out, neither is cancer. Tumors are surrounded by a complex non-cancerous ecosystem containing immune, stromal, and vascular cells, diverse cytokines, and immune checkpoints.1 Scientists have discovered that this tumor microenvironment (TME) plays a crucial role throughout cancer development, from initiation to metastasis. Developing tumors can distort immune cell signaling to drive chronic, damaging inflammation, which promotes both tumor progression and resistance to therapy.1,2 The TME also supports tumoral immune evasion. Myeloid cells,…
