Credit: Salk Institute Minutes after you eat a meal, as nutrients rush into your bloodstream, your body makes massive shifts in how it breaks down and stores fats and sugars. Within half an hour, your liver has made a complete switch, going from burning fat for energy to storing as much glucose, or sugar, as possible. But the speed at which this happens has puzzled scientists — it’s too short a time span for the liver’s cells to activate genes and produce the RNA blueprints needed to assemble new proteins to guide metabolism. Now, Salk researchers have uncovered how the liver can have such a speedy response to food; liver cells store up pre-RNA molecules involved in glucose and fat metabolism. “The switch from fasting to feeding is a very quick switch and our physiology has to adapt to it in the right time frame,” says Satchidananda Panda, a professor in the Salk Institute’s Regulatory Biology Laboratory. Their paper “Now we know how our body quickly handles that extra rush of sugar” was published in the journal Cell Metabolism. It was known that a RNA-binding protein “NONO” was associated in regulating daily rhythms in the body. But Panda’s group wondered whether NONO had a specific role in the liver. They analyzed levels of NONO in response to feeding and fasting in mice. After the animals ate, speckled clumps of NONO suddenly appeared in their liver cells, newly attached to RNA molecules. Within half an hour, the levels of corresponding proteins — those encoded by the NONO-bound RNA — increased. “After mice eat, it looks as if NONO brings all these RNAs together and processes them so they can be used to make proteins,” says Panda. When mice lacked NONO, it took more than three hours for levels of the same proteins, involved in processing glucose, to increase. During that time lag, blood glucose levels shot up to unhealthy levels. Since blood glucose levels are also heightened in diabetes, the researchers think that the mice without NONO may act as a model to study some forms of the disease. “Understanding how glucose storage and fat burning are regulated at the molecular level will be important for the development of new therapies against obesity and diabetes,” says Benegiamo.

Yоu've prоbаbly heаrd pоlice officers on television repeаt the same line every single time they arrest someone: "You have the right to remain silent." Have you ever wondered why they always say this? As it turns out, all police officers in the country are required by law to say these words, which are called "Miranda Rights." They are named after a famous court case from 1966, Miranda v. Arizona. The Case In 1966, an Arizona man named Ernesto Miranda was accused of kidnapping and assaulting a teenage girl. After a few hours of questioning, he confessed his guilt to a police officer. Later, during his trial, the prosecution used his confession as evidence to convict him. When the court did find him guilty, his lawyers appealed the case. The case went all the way to the Supreme Court. The case related to the Constitution, because the Fifth Amendment gives everyone the right to stay quiet when they are asked to confess to a crime. Miranda's lawyers argued that Miranda did not know about this right, and therefore his testimony could not count as evidence in the trial. The Result Since Miranda did not know about his Fifth Amendment rights, his confession could not be used against him, and the Supreme Court ruled in his favor. The official court decision was over sixty pages long, but Chief Justice Earl Warren read the whole thing out loud for the court. It had two parts: First, after the police arrest someone, they have to tell the person they have the right to remain silent, just as it is stated in the Fifth Amendment. Second, the police also have to tell that person they have the right to use a lawyer in the trial and any time prior to that, and that if they cannot afford a lawyer, the government will provide them with one. These rights are both found in the Sixth Amendment. This is why you always hear police officers reciting these important rights whenever they arrest someone. They are called "Miranda Rights" today. Miranda Rights Today The basic wording might sound familiar. "You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford an attorney, one will be appointed to you. do you understand these rights as I have read them to you?" However, there are actually over 945 versions of the Miranda Rights! Every state and county can have its own wording. Not only that, but the Miranda Rights also have to be translated into many different languages, in case the police arrest someone who does not speak English. There are also simplified versions, because it is important for minors and the mentally disabled or mentally ill to understand their rights as well. Some researchers have analyzed the wording of Miranda Rights from all over the country, and most versions are too complex for everyone to understand. Some are so complex, they are at the same reading level as a college textbook! It is extremely important that everyone can understand that their right to remain silent and their right to be represented by a lawyer. The law says that, in order to use a suspect's own confession against him, the court has to prove that the police read them their rights, they completely understood their rights, and that they chose to ignore those rights intentionally. The Constitution gave us these rights for a reason; make sure you understand them! What does the word "convict" most closely mean as it is used in paragraph 2?
