These buttons have taken the pet world by storm, leading to impressive and sometimes seemingly miraculous feats shared across platforms like TikTok and Instagram. But are these dogs truly communicating, or are they just responding to cues from their owners? Now, a new study published in PLOS ONE – by researchers from the University of California San Diego and other institutions – ...

Researchers at the University of Massachusetts Amherst and UMass Chan Medical School have demonstrated in mice a new method to combat pancreatic cancer. The study, published in Science Translational Medicine, outlines the synergistic effects of a novel nanoparticle drug-delivery system to activate an immune pathway in combination with tumor-targeting agents.    Pancreatic ductal adenocarcinoma (PDAC) is the most common form of pancreatic cancer. With a dismal,13% five-year survival rate, it is the third leading cause of cancer deaths.   One major ...

An archaeogenetic study sheds new light on the isolated medieval community Las Gobas in northern Spain. Besides isolation and endogamy, the researchers have also identified the variola virus which can offer a new explanation on how smallpox entered Iberia. Researchers from Sweden and Spain have conducted a comprehensive archaeogenetic study on a community that lived on the border between the northern Christian kingdoms and Al-Andalus during the early Medieval period. This dynamic era, especially ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the experiments published August 28 in Nature show that DNA replication in early embryos is different from what past research has taught, and includes a period of instability that is prone to chromosomal copying errors. As failed pregnancies and developmental disorders are often related to chromosomal abnormalities the findings could impact the field of reproductive medicine, perhaps leading to improved methods of in vitro fertilization (IVF). During embryogenesis, ...

NEW YORK, NY (Aug. 28, 2024)--An analysis of more than 1.6 million brain cells from older adults has captured the cellular changes that occur in the early stages of Alzheimer’s disease, potentially revealing new routes for preventing the most common cause of dementia in older individuals. The study also identified a second community of cells that drives the older brain down a different path that does not lead to Alzheimer’s disease.  “Our study highlights that Alzheimer’s is a disease of many cells and their interactions, not just a single type of dysfunctional ...

When it comes to survival, plants have a huge disadvantage compared to many other living organisms: they cannot simply change their location if predators or pathogens attack them or the environmental conditions change to their disadvantage. For this reason, plants have developed different strategies with which they react to such attacks. Such reactions are usually triggered by certain signals from the environment. As has long been known, the intracellular calcium concentration plays an important role in the processing of these signals. However, in addition to changes in the cytoplasmic calcium level, changes in the cell's ...

A pivotal study has pinpointed a gene module crucial for enhancing walnut trees' resistance to anthracnose, a widespread fungal disease threatening the walnut industry. The research reveals how the JrPHL8-JrWRKY4-JrSTH2L module regulates disease defense, opening up new opportunities for breeding resistant walnut varieties and promoting sustainable cultivation practices. Anthracnose, caused by Colletotrichum gloeosporioides, poses a significant threat to walnut production, causing severe losses ...

Roadway-related incidents are a leading cause of flood fatalities nationwide, but limited flood-reporting tools make it difficult to evaluate road conditions in real time. Existing tools — traffic cameras, water-level sensors and even social media data — can provide observations of flooding, but they are often not primarily designed for sensing flood conditions on roads and do not work in conjunction. A network of sensors could improve situational flood level awareness; however, they are expensive to operate at scale. Engineers at Rice University have developed a possible solution to this problem: an automated data ...

Male fruit flies will become oblivious to physical danger as they become more engaged in courtship and sex, new research shows. Researchers at the University of Birmingham have shown that pursuit of a coveted reward – in this case a female fly – will cause a male fruit fly to ignore threats such as predation. In the study, published today (28 Aug) in Nature, the team was able to show for the first time the neural networks in the fly’s brain that direct this decision-making process, revealing the neurotransmitter dopamine has a leading role to play. Lead researcher Dr Carolina Rezaval said: “Every day we make decisions that require us to ...

The risk of death for people who donate a kidney for transplantation — already small a decade ago — has dropped by more than half since then, a new study shows. Each year, roughly 6,000 Americans volunteer to donate a kidney, according to the Organ Procurement and Transplantation Network. Before undergoing the procedure, donors are informed of the potential risks, including death. Based on data from 1995 through 2009, experts had originally predicted that about three of every 10,000 donors were likely to die within three months of the procedure. The authors of the ...

About The Study: Perioperative mortality after living donation declined substantially in the past decade compared with prior decades, to fewer than 1 event per 10,000 donations. Risk was higher for male donors and donors with a history of hypertension. Current guidelines for donor informed consent, based on 2009 data, should be updated to reflect this information.
