Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

New tool could help detect smaller concentrations of drug powders

In 2017, more than 28,000 cases of fatal overdoses in the United States involved fentanyl. Just a pinch of the synthetic opioid, estimated to be 100 times stronger than morphine, can be lethal.

Botanical product kratom may cause liver toxicity and injury, study finds

Data from a new study presented this week at The Liver Meeting – held by the American Association for the Study of Liver Diseases – found that kratom, a popular and widely available product, may cause liver toxicity and severe liver injury.

Study uncovers how cells 'forget their past' while developing into a specific cell

All cells in the body contain the same genetic material. The difference between cells therefore depends solely on which genes are expressed or ‘turned on’.

Researchers analyze levels of spicy compounds in chili peppers during ripening

Anyone who has tasted a hot chili pepper has felt the burn of capsaicinoids, the compounds that give peppers their spiciness, as well as possible health benefits.

Signs of frailty could be identified through a new assessment

Signs of frailty, and the risks it brings, could be identified in young and old people alike through a new assessment developed in a study led by researchers at the University of Strathclyde.

Researchers make major breakthrough in cell signalling

Researchers at the University of Liverpool have made a major breakthrough in the field of cell signalling.

Varied diets may be the cause for differences in human and non-human primate saliva

The study, published recently in Molecular Biology and Evolution, describes the discovery that human saliva is much more watery than the saliva of chimpanzees and gorillas.

Risky strategy allows malaria parasite to quickly respond to unpredictable changes

The parasite that causes malaria expresses genes that code for the proteins it will need in later life stages, using two separate schemes to prevent these proteins from actually being made until they are needed, according to new research.

Increasing anti-tumor activity of compound extracted from an Amazon plant

Researchers in Brazil have prepared modified forms of the alkaloids produced by Uncaria guianensis, a woody vine native to the Amazon Rainforest.

Researchers identify new kidney cancer subtypes and clues to better diagnosis, treatment

In what is believed to be the most comprehensive molecular characterization to date of the most common - and often treatment-resistant - form of kidney cancer, researchers at Johns Hopkins' departments of pathology and oncology, Johns Hopkins Kimmel Cancer Center, and the Johns Hopkins University School of Medicine report evidence for at least three distinct subtypes of clear cell renal cell carcinoma (ccRCC), along with new revelations about the proteins that define them.

Some types of proteins can stabilize damaged DNA

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins cannot keep their DNA stable and develop diseases such as cancer.

White and brown fat cells send very different signals to rest of the body

Many people might not realize that they have different types of body fat. Most of it is white fat that sits on your stomach, hips and thighs, for example. White fat is an energy storage that our body can use when food is scarce.

UChicago researchers reveal the secret of cancer-related Warburg effect

A new study, led by researchers at the University of Chicago, provides an answer to why cancer cells consume and use nutrients differently than their healthy counterparts and how that difference contributes to their survival and growth.

Heuneburg Early Celts from all social classes may have used local ceramics to consume Mediterranean wine

Early Celts from the Heuneburg settlement may have enjoyed Mediterranean wine well before they began importing Mediterranean drinking vessels—and this special drink may have been available to all in the community, according to a study published October 23, 2019 in the open-access journal PLOS ONE by Maxime Rageot from Ludwig-Maximilians-Universität München and the University of Tübingen, and colleagues.

Researchers identify compounds that could help study the toxicological properties of fire ant venom

Native to South America, imported fire ants have now spread to parts of North America and elsewhere around the world. These invasive pests have painful stings that, in some cases, can cause serious medical problems, such as hypersensitivity reactions, infections and even kidney failure.

Subtle changes in mitochondrial DNA can have profound consequences for patient's health

Subtle changes in the DNA of mitochondria, the tiny power plants within cells, can have profound consequences for a patient's health.

Scientists develop more accurate method to find good targets for cancer immunotherapy

Ludwig Cancer Research scientists have developed a new and more accurate method to identify the molecular signs of cancer likely to be presented to helper T cells, which stimulate and orchestrate the immune response to tumors and infectious agents.
