Radiation may be the biggest threat to humans living on another planet.

To ensure astronaut health and safety, scientists are investigated several means of radiation protection. The optimal mixture is surprisingly rustic, they find.

The application of mechanic forces to the cell nucleus affects the transport of proteins through the nuclear membrane, an action that controls cellular processes and could play a key role in several diseases such as cancer. These findings draw a new scenario for understanding how the mechanic forces drive the progression of cancer and open the doors to the design of potential innovative techniques—both diagnostic and therapeutic. This is the conclusion of a study published in the journal Nature Cell Biology led by lecturer Pere Roca-Cusachs, from the Faculty of Medicine and Health Sciences of the University of Barcelona, the Institute of Nanoscience and Nanotechnology of the UB (IN2UB) and the Institute for Bioengineering of Catalonia (IBEC).

The cells in the body receive mechanical stimuli from their environment and respond accordingly regarding decisions on how and when to grow, move and differentiate. The process is known as mechanotransduction and it is critically important for the cell function and for human health.

The study reveals that the direct application of force to the nucleus can affect the spatial organization of the DNA and the activity of nuclear proteins, among other functions. When cancer cells invade the organs and metastasis appears, these create physical forces that are transmitted to the cell nucleus.

No one should think we are over COVID.

WASHINGTON — Federal health officials warned on Wednesday that a third of Americans live in areas where the threat of Covid-19 is now so high that they should consider wearing a mask in indoor public settings. They cited new data showing a substantial jump in both the spread of the coronavirus and hospitalizations over the past week.

Dr. Rochelle P. Walensky, the director of the Centers for Disease Control and Prevention, said that the seven-day average of hospital admissions from Covid rose 19 percent over the previous week. About 3,000 people a day were being admitted with Covid, she said, although death rates, a lagging indicator, remained low.

Summary: An older person’s posture may give clues to hidden cognitive decline, a new study reports.

Source: Shinshu University.

A mass survey of citizens aged 50 to 89 years examined whether cognitive decline could be detected by sagittal spinal balance measurement based on a radiological approach. Doctors from Shinshu University observed associations of sagittal vertical axis (SVA) anteriorization and higher age with lower cognitive function.

“When the Human Genome Project began in 1990, it had a projected budget of $3 billion. […] Now, one company claims to have achieved the major milestone of whole genome sequencing for just $100.”

Ultima Genomics, a biotech company based in California, has emerged from stealth mode with a new high-throughput, low-cost sequencing platform that it claims can deliver a $100 genome.

When the Human Genome Project began in 1990, it had a projected budget of $3 billion. Some researchers believed it would take centuries to map all 20,000+ genes and to determine the sequence of chemical base pairs making up DNA, though in the end it took 13 years. Since then, genome sequencing has undergone technology and cost improvements at a rate faster than Moore’s Law (a long-term trend in the computer industry that involves a doubling of performance every two years). What used to require billions of dollars and many years of work is now several orders of magnitude cheaper and possible in a matter of hours.

Numerous activities, including construction and demolition, mining and industrial activities, cooking and gardening, and others, generate a substantial amount of garbage. The amount of waste generated is directly proportional to consumption and production patterns.

In most cases, waste formation is the result of inefficient material utilization. Trends in the number, composition and impacts of these materials provide insight into the nation’s efficiency in using (and reusing) materials and resources. It also provides a better understanding of the effects of waste on human health and the environment.

According to surveys, 92 million tonnes of cloth are dumped as garbage each year worldwide. Estimates predict that this figure will likely exceed 130 million tonnes by 2030. When 200 tonnes of water used to make a single tonne of fabric is considered, it becomes clear that the end-to-end processes of the garment industry are severe threats to environmental initiatives.

Wearable sensors—an important tool for health monitoring and for training artificial intelligence—can be waterproof or can measure more than one stimuli, but combining these factors while maintaining a high level of precision in the measurements is difficult. Researchers co-led by Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics at Penn State, have created sensors that are waterproof, an important trait for exercise monitoring and for withstanding perspiration and all weather conditions; can measure temperature and motion on both small and large scales; and can be attached to distal arteries such as those located beneath the eyebrow or in a toe.

The results are available now online in the Chemical Engineering Journal ahead of publication in the journal’s September print edition.

“There are three aspects of this that are novel in combination: the underwater application, the ability to detect ultra-small vibrations and subtle motions and temperature changes, and the multiple options for sensor location, such as the eyebrow or toe,” Cheng said.
