WASHINGTON, Sept. 11, 2023 — What does it mean to have “cooked” something? Is heat the only way to break down proteins and transform raw ingredients? If you love ceviche, you know that’s not true … but how exactly does ceviche get “cooked?” No heat source is used, but it still undergoes a process in which proteins are denatured. We’re taking a closer look at proteins, how they denature and what that means for the food on your plate. https://youtu.be/Pw6apr3TBzY?si=RdIYP5j3B0daGtxw Reactions ...

This work, led by Roger Vila, a scientist at the IBE, with Mattia Menchetti as its first author, an INPhINIT ”la Caixa” ...

A healthy lifestyle that involves moderate alcohol consumption, a healthy diet, regular physical activity, healthy sleep and frequent social connection, while avoiding smoking and too much sedentary behaviour, reduces the risk of depression, new research has found. In research published today in Nature Mental Health, an international team of researchers, including from the University of Cambridge and Fudan University, looked at a combination of factors including lifestyle factors, genetics, brain structure and our immune and metabolic systems to identify the underlying mechanisms that might explain this link. According ...

One of the most invasive species in the world is Solenopsis invicta, a red fire ant species with a painful sting. Native to South America, the ant has established itself across the globe. In an article publishing in the journal Current Biology on September 11, a group of ant experts confirm that the species has made its way to Sicily—the ant’s first official sighting in Europe. The ants could soon spread all over the continent, the researchers warn, which could cause major environmental, health, and economic problems in Italy and ...

The discovery of a previously unknown molecular target has inspired what may become a therapeutic breakthrough for people with glioblastoma, the most common and aggressive brain cancer.  When people hear the word “cancer” they often picture a single mass, but glioblastoma cells are also highly invasive and spread quickly from the central mass, making it very difficult to fully eradicate. Even with current treatments such as temozolomide, the standard chemotherapy approved to treat glioblastoma, ...

The sequencing of the human genome promised a revolution in medicine, but scientists soon realized that a genetic blueprint alone does not show the body in action. That required understanding the proteome – all the proteins, expressed by our genes, forming the cellular machinery that performs the bulk of the body’s functions. Now, another set of molecules known as the lipidome – all the lipids in our bodies – is filling in more details of human physiology. Lipids are a broad category of small, fatty or oily molecules, including triglycerides, cholesterol, hormones ...

Plants have evolved diverse adaptive strategies to optimize the exploration of light and soil resources from their environments. One of the most prominent adaptive responses is the developmental plasticity of their root systems, which enables plants to efficiently forage nutrient pools that fluctuate in space and time. As a crucial component determining the active root surface, root hairs represent a powerful morphological trait to improve water and nutrient acquisition. Root hairs are extensions of epidermal cells that effectively enlarge the root surface area and facilitate soil exploration for water and nutrients. Root hair development starts with cell fate specification, which ...

Having a hobby is linked to fewer depressive symptoms and higher levels of happiness, self-reported health and life satisfaction among people aged 65 and over, and this holds true across 16 countries on three continents, according to a new study led by UCL (University College London) researchers. The study, published in the journal Nature Medicine, aimed to see if the benefits of hobbies were consistent in different national settings, and looked at data from 93,263 people aged 65 or over who had enrolled in five existing longitudinal studies in England, Japan, United States, China and 12 European countries. Analysing data from participants spanning four to eight ...

Women who have been treated for cancer as a child with a certain type of chemotherapy have an increased risk of breast cancer, according to a large-scale international study of survivors of childhood cancer led by scientists from the Princess Máxima Center for pediatric oncology. The results were published today, 11 September, in the leading journal Nature Medicine and point to the need for earlier breast cancer screening in women who have previously been treated with this chemotherapy and radiation for childhood cancer.   Three out of four children with cancer are successfully treated ...

The globe was hot and humid. The sea was teeming with life. Early squids, eel-like fish and sea worms hunted smaller animals. Above ground, however, nothing stirred. The animals had not yet crawled ashore. That was what the Earth looked like about 450 million years ago at the end of the Ordovicium period. The warm water created the perfect living conditions for wildlife. But this would soon change. Shortly after, the land masses would began to freeze and an ice cap start to spread.  The water, which had ...

Understanding the interactions between materials and chemical species is critical for engineers as it helps them determine their best uses for both day-to-day life and global-level applications.  Metal oxides, a binary material of metal and oxygen, greatly interest researchers because of their importance in transforming energy storage, production, and conversion. To further those possibilities, a team from the University of Pittsburgh Swanson School of Engineering has determined a new way to view how hydrogen and metal oxides interact.  “Numerous experimental techniques have been used to understand this phenomenon – from spectroscopy to catalysis” explained Giannis ...

Key points:  The PIP3/PI3K signalling pathway is one of the most important signalling mechanisms in our cells, affecting cell metabolism and growth. It is also one of the most frequently altered pathways in human cancer. Research from the Institute has shown that PI3K pathway remodelling is a common feature of cancers driven by hyperactivated PI3K signalling. Working in prostate tumour models the team identified an unknown activator driving PI3K signalling and cancer growth in a way that is released both from needing positive growth signals and also from growth-limiting feedback controls. This knowledge identifies new ...

“Mistrust all in whom the impulse to punish is powerful,” warned Friedrich Nietzsche more than a century ago.  Instead, the impulse to punish appears to have grown more and more powerful in the U.S criminal justice system. Annually, more than 9 million people a year in the U.S. are arrested, and on any given day roughly 2.3 million are incarcerated, representing a 500% increase in the prison and jail population since 1980 (compared to a 46% increase in the population over the same time).  This ...

A company co-founded by a University of Bath graduate has opened the UK’s first pilot plant that can recycle up to 60% of plastic lab waste, to make back into new lab consumables. LabCycle hopes the technology could be scaled up in the future to recycle waste from healthcare, research and commercial labs that is currently incinerated or sent to landfill. To avoid cross-contamination between experiments, most lab-based scientists use a significant amount of single-use plastic in their daily research, including pipette tips, test tubes, petri dishes and multi-well ...

Underwater imaging plays a critical role in many fields such as marine exploration, oceanographic engineering, environmental protection and identifying dangerous objects on the ocean floor. However, in turbid or turbulent waters, image quality is often severely degraded due to the complexities of the underwater environment and equipment limitations. Underwater captured images often suffer from contrast loss because light is scattered and absorbed as it travels in water, resulting in major degradation of detail and distorted or blurred images. A new invention about the size of a ...

COLUMBUS, Ohio – Using artificial intelligence applications to help craft a message to a friend is not a good idea – at least if your friend finds out about the use of AI, a new study suggests.   Researchers found that people in the study perceived that a fictional friend who used AI assistance to write them a message didn’t put forth as much effort as a friend who wrote a message themselves.   That perception may be understandable, but the effect goes beyond the message itself, said Bingjie Liu, lead author of the study and assistant professor of communication at The Ohio State University.   “After ...
