Deep Space Travel Cause Cancer in Astronauts

When Elon Musk unveiled SpaceX's plans for sending humans to Mars in September 2016, he had a remarkably cavalier attitude towards the dangers of space radiation. There's going to be some risk of radiation, but it's not deadly," he told the audience in Guadalajara, Mexico back then.

There will be some increased risk of cancer, but I think it's relatively minor. The radiation thing is often brought up, but I think it's not too big of a deal. The study was published in the journal Proceedings of the National Academy of Sciences.

Eczema Drug Restores Hair Growth In Alopecia Patient

Massachusetts General Hospital (MGH) physicians are reporting an unexpected side-effect from treatment with dupilumab, which is FDA approved for the treatment of moderate to severe eczema, also called atopic dermatitis.

The study was published in JAMA Dermatology, the physicians describe how their 13-year-old patient, who has alopecia totalis, a total lack of scalp hair along with eczema, experienced significant hair regrowth while being treated with dupilumab, a drug marketed under the brand name Dupixent.

Losing One Hour Of Sleep Impact On Human Health

We all have nights where we do not get as much sleep as we would like. But missing out on even an hour can impact our health. While an hour may not really seem like a long time, 60 minutes of lost sleep can have an effect on your body.

Research has shown that an hour of sleep may cause increased appetite something like 200 more calories the day after the change kicks in as well as reduced exercise endurance and decreased productivity.

Sleep Apnea Condition Disturbing Night Sleep

When it comes to disorders affecting sleep, sleep apnea ranks on top with an estimated 936 million people worldwide suffering from the condition, the latest study has suggested. Sleep apnea is a chronic sleep-disordered breathing condition associated with increased risk of mortality and reduced quality of life.

Serum Prolactin In Pregnancy Predicts Prediabetes

Researchers found that women with the highest levels of the hormone, although still in the normal range, had a 27% reduced risk of developing type 2 diabetes compared to those with the lowest levels in the normal range.

Prolactin is a multi-function hormone-it is not only related to pregnancy and breastfeeding, but it also plays an important role in many other biological functions, like metabolism, immune regulation, and water balance. The study was published in the Diabetologia.

Differences In Brain Structure Among Patients With Schizophrenia

Schizophrenia is an extremely variable psychiatric disorder that is diagnosed based on the presence of specific symptoms. Thomas Wolfers and André Marquand of Radboud university medical center investigated how much the brains of individual patients diagnosed with schizophrenia differ from the 'average' patient.

For this purpose, they compared brain scans of 250 healthy individuals with those of 218 individuals with schizophrenia. Those with schizophrenia as a group differed from the healthy individuals in frontal brain regions, the cerebellum, and the temporal cortex. The study was published in JAMA Psychiatry.

Attacking RNA With Small-Molecules Drugs

Yale has developed a way to target RNA with small-molecule drugs, creating a new method for tapping into a vast number of biological mechanisms critical to metabolism and gene expression.

"There is tremendous interest in targeting RNA with small molecules," said Yale biochemist Anna Pyle, whose lab conducted the research. Despite this potential, there has been limited progress on the development of small-molecule drugs that bind RNA, and a pervasive view that RNA is not a viable therapeutic target.

Survey Uncovers Delay In Diagnosing Bone Cancer

A survey undertaken by the Bone Cancer Research Trust (BCRT) has revealed a diagnosis of breast cancer patients. The survey of 394 primary bone cancer patients, survivors, and bereaved families showed that one in four patients (26%) had waited over seven months before receiving a diagnosis with 13% waiting over a year
