A new study says that changing guidelines for forever chemicals have made rainwater all around the world unsafe to drink.

Rainwater is an important part of our planet’s ecosystem, and it helps fuel access to drinking water in many places. However, a new study suggests that rainwater is now unsafe to drink. The study says that “forever chemicals” have reached unsafe levels. These forever chemicals are scientifically known as per-and poly-fluoroalkyl substances (PFAS), and they don’t break down in the environment.

You can find PFAS chemicals in non-stick and stain-repellent properties. As such, they’re found in a lot of household food packages, electronics, and even cosmetics and cookware. However, it seems that these chemicals are now mixing with our rainwater. As a result, it has made rainwater unsafe to drink. And researchers say they can’t tie this issue to just one location. It’s everywhere in the world, even in Antarctica.

The researchers say that the guideline levels for forever chemicals have dropped significantly over the past 20 years. That’s because new insight into just how toxic these chemicals are to the human body has come to light. As such, the values for PFAS in drinking water to be considered toxic have dropped quite a bit. As a result, the current levels of one particular chemical would deem rainwater unsafe to drink.

The results emphasized the role of body posture and stomach motility in drug bioavailability.

* Researchers from Johns Hopkins University and Johns Hopkins School of Medicine have conducted a study to examine how body posture and stomach motility affect drug bioavailability. * Stomach contents, motility, and gastric fluid dynamics are also influential factors in a drug’s bioavailability. * “Our models can generate biorelevant data on drug dissolution that can provide useful and unique insights into the complex physiological processes behind the oral administration of pills,” explains the study.

Many of you’ve probably swallowed a medicine sometime in your lives. It’s very common, and many drugs are taken orally, such as tablets, capsules, syrups, or lozenges.

Even though oral medication is one of the most common types of treatment due to the fact that it’s cheap and easy to apply, it comes with a complex downside. Oral administration is actually complicated for the human body to absorb an active pharmaceutical ingredient. This is because the drug’s bioavailability (rate and extent of absorption) in the gastrointestinal tract depends on the medication’s components and the stomach’s dynamic physiological environment.

Circa 2021 immortality of the pancreas by inducing pluripotent cells of the pancreas.

A microwell chip facilitates the single-cell characterization of the differentiation of aggregates of human induced pluripotent stem cells into pancreatic duct-like organoids and the discovery of secreted markers of pancreatic carcinogenesis.

Circa 2021 Basically this article details cannabinoids that have been successfully synthesized which can lead to even greater psychiatric medicine aswell as many of other types of uses.

Abstract Cannabis has been integral to Eurasian civilization for millennia, but a century of prohibition has limited investigation. With spreading legalization, science is pivoting to study the pharmacopeia of the cannabinoids, and a thorough understanding of their biosynthesis is required to engineer strains with specific cannabinoid profiles. This review surveys the biosynthesis and biochemistry of cannabinoids. The pathways and the enzymes’ mechanisms of action are discussed as is the non-enzymatic decarboxylation of the cannabinoic acids. There are still many gaps in our knowledge about the biosynthesis of the cannabinoids, especially for the minor components, and this review highlights the tools and approaches that will be applied to generate an improved understanding and consequent access to these potentially biomedically-relevant materials.

A team of researchers in the Faculty of Engineering of The University of Hong Kong (HKU) has developed a coin-sized system that can read weak electrochemical signals and can be used for personalized health monitoring and the measurement of such conditions as diabetes, cardiovascular diseases and mental health. The discovery was featured on the cover of Analytical Chemistry.

The PERfECT System—an acronym for Personalized Electronic Reader for Electrochemical Transistors—is the world’s smallest system of its kind, measuring 1.5 cm x 1.5 cm x 0.2 cm and weighing only 0.4 gram. It is easily wearable, for instance integrated with a smartwatch or as a patch, to allow for continuous monitoring of biosignals such as glucose levels and antibody concentrations in blood and even sweat.

“Our wearable system is tiny, soft and imperceptible to wearers, and it can do continuous monitoring of our body condition. These features mean it has the potential to revolutionize health care technology,” said Dr. Shiming Zhang of the Department of Electrical and Electronic Engineering, who leads the HKU WISE (wearable, intelligent and ) Research Group to develop the system.
