Multiple people were killed and more than 30 others injured in large crashes involving up to 90 vehicles on Interstate 55 in south-central Illinois during a dust storm, authorities said Monday afternoon.

According to Illinois State Police, multiple fatalities were reported with the crashes, but an exact number remained unclear. At least 30 others, ranging in age from 2 to 80 years old, were taken to area hospitals. Their conditions weren’t immediately known.

Authorities said they were still conducting additional searches through the vehicles involved, which included an estimated 30 commercial vehicles and 40 to 60 passenger cars. The biggest challenge, according to Illinois State Police Major Ryan Starric, the biggest challenge was trying to get to victims quickly.

Patients with kidney failure have a high mortality rate. There is an exponential increase in the number of patients experiencing kidney failure requiring treatment with life-saving kidney replacement therapy (KRT), including hemodialysis (HD), peritoneal dialysis (PD) or kidney transplantation.

Researchers have found inj a new study that Intradialytic exercise may improve survival rates in adult patients receiving hemodialysis.

The new study has been published in the BMC Nephrology.

From early detection and internal treatment of diseases to futuristic applications like augmenting human memory, biological computing, or biocomputing, has the potential to revolutionize medicine and computers.

Traditional computer hardware is limited in its ability to interface with living organs, which has constrained the development of medical devices. Computerized implants require a constant supply of electricity, they can cause scarring in soft tissue that makes them unusable and they cannot heal themselves the way organisms can. Through the use of biological molecules such as DNA or proteins, biocomputing has the potential to overcome these limitations.

Biocomputing is typically done either with or with non-living, enzyme-free molecules. Live cells can feed themselves and can heal, but it can be difficult to redirect cells from their ordinary functions toward computation. Non-living molecules solve some of the problems of live cells, but have weak output signals and are difficult to fine-tune and regulate.

Revolutionizing the process of heart monitoring, researchers have developed a wearable e-tattoo that provides continuous heart monitoring outside of a clinical setting.

A team of researchers from The University of Texas at Austin has created a flexible and wearable medical device that could transform the fight against heart disease. This device called an electronic tattoo or e-tattoo, can be attached to the chest to continuously monitor the heart outside of clinical settings.

The e-tattoo is wireless and mobile, as it has small active circuits and sensors linked by stretchable interconnections. The device weighs just 2.5 grams and can be worn comfortably with a medical dressing.

AUSTIN, Texas — Researchers behind discoveries that led to vaccines for the virus that causes COVID-19 have identified a potential Achilles heel that exists in all coronaviruses. These findings, led by researchers at The University of Texas at Austin, could aid the development of improved treatments for COVID-19 and also protect against existing and emerging coronaviruses.

Most vaccines and antibody-based treatments for COVID-19 neutralize the SARS-CoV-2 virus by disrupting interactions between the protein spike on the virus and the ACE2 receptor on human cells, which the virus hijacks to gain entry. But mutations in the spike protein mean that emerging variants of SARS-CoV-2 can escape the human antibody response, making treatments less effective and leading to vaccinated individuals still experiencing breakthrough infections. The researchers are addressing the issue by focusing on parts of the spike protein that are crucial for the virus’s survival and don’t mutate.

The SARS-CoV-2 spike protein is made up of two subunits – called S1 and S2. The S1 subunit binds to the ACE2 receptor, while the S2 subunit allows the virus to fuse with the membrane of the cell it is gaining access to. Most mutations in the spike protein affect its S1 subunit, but the S2 part is relatively constant across all seven human coronaviruses, making it a prime target for therapeutic antibodies and vaccines.

According to the research, published in the journal EMBO Molecular Medicine, the nanoparticles are used to eliminate obstacles in the malignant tumor’s environment that impede the normal activity of natural killer cells (a special sub-type of white blood cells called lymphocytes).

As one of the OMICS in systems biology, metabolomics defines the metabolome and simultaneously quantifies numerous metabolites that are final or intermediate products and effectors of upstream biological processes. Metabolomics provides accurate information that helps determine the physiological steady state and biochemical changes during the aging process. To date, reference values of metabolites across the adult lifespan, especially among ethnicity groups, are lacking. The “normal” reference values according to age, sex, and race allow the characterization of whether an individual or a group deviates metabolically from normal aging, encompass a fundamental element in any study aimed at understanding mechanisms at the interface between aging and diseases.

While the world has been captivated by recent advances in artificial intelligence, researchers at Johns Hopkins University have identified a new form of intelligence: organoid intelligence. A future where computers are powered by lab-grown brain cells may be closer than we could ever have imagined.

What is an organoid? Organoids are three-dimensional tissue cultures commonly derived from human pluripotent stem cells. What looks like a clump of cells can be engineered to function like a human organ, mirroring its key structural and biological characteristics. Under the right laboratory conditions, genetic instructions from donated stem cells allow organoids to self-organize and grow into any type of organ tissue, including the human brain.

Although this may sound like science-fiction, brain organoids have been used to model and study neurodegenerative diseases for nearly a decade. Emerging studies now reveal that these lab grown brain cells may be capable of learning. In fact, a research team from Melbourne recently reported that they trained 800,000 brain cells to perform the computer game, Pong (see video). As this field of research continues to grow, researchers speculate that this so-called “intelligence in a dish” may be able to outcompete artificial intelligence.

The protective effects of vaccines have particularly been highlighted during the recent COVID-19 pandemic. Countries able to offer the vaccine demonstrate lowered infection rates and have kick-started the recovery of their economies.

The COVID-19 pandemic has also highlighted the need to proactively develop medical countermeasures to novel pathogens, in addition to advancing supply and manufacturing capacities to meet global demands.

Investing in vaccine manufacturing has both economic and societal benefits, in addition to protecting human health and limiting infection spread.
