Antibody Removes Abnormal Proteins from Cancer Cells

Posted by in category: biotech/medical

Antibodies are used in many kinds of cancer treatments but have only been able to reach proteins on the outside of cancer cells—until now. According to a new study, scientists have designed antibodies that can barge into cancer cells and drag abnormal proteins out, ultimately slowing tumor growth in mice.

The approach is a novel way of targeting cancer-fueling proteins that are buried inside cancer cells, several experts said.

Most antibodies can’t get inside cells. Yet most cancer-fueling proteins are tucked deep inside cancer cells. One type of antibody, however, called IgA, can glide through certain cells like a ghost walking through a wall.

Lung Cancer Death Rates Continue to Decline

Posted by in categories: biotech/medical, health

NCI researchers have found a persistent decline in rates of both smoking-related and non-smoking-related lung cancer deaths.


In the U.S., lung cancer death rates have declined for decades, primarily due to decreases in cigarette smoking. However, it is unclear whether rates of smoking-unrelated lung cancer deaths are also decreasing. If the rates are increasing, that may suggest increases in exposure to other lung carcinogens that need to be investigated. Meredith Shiels, Ph.D., M.H.S., senior investigator in the Infections and Immunoepidemiology Branch, and colleagues in the Biostatistics Branch, the Division of Cancer Control and Population Sciences, and Information Management Services, conducted a study to estimate trends in U.S. lung cancer death rates from 1991–2018. They found that both smoking-attributable and smoking-unrelated lung cancer death rates declined over this period. The findings were published in the Journal of the National Cancer Institute on December 9, 2023.

Cancer registries and death certificates do not collect the smoking status of every person diagnosed with or who died from lung cancer. Thus, to estimate trends in lung cancer death rates by smoking status, the researchers needed another way to determine the age-specific trends in lung cancer deaths attributed to smoking, and unrelated to smoking. They estimated age-specific annual percentage of lung cancer deaths that could be attributed to smoking using smoking status data from the National Health Interview Survey linked to death certificate data. These population attributable fractions were then multiplied by national data on lung cancer mortality to estimate trends over time in smoking-attributable and smoking-unrelated deaths. The researchers found that the fraction of lung cancer deaths attributable to smoking decreased from 82% in 1991 to 75% in 2018. Over this same period, smoking-attributable lung cancer death rates declined 2.

The 5th Industrial Revolution as an engine for human longevity

Posted by in categories: bioengineering, biotech/medical, blockchains, genetics, internet, nanotechnology, quantum physics, robotics/AI

Before delving into the prospects of the Fifth Industrial Revolution, let’s reflect on the legacy of its predecessor. The Fourth Industrial Revolution, characterised by the fusion of digital, physical, and biological systems, has already transformed the way we live and work. It brought us AI, blockchain, the Internet of Things, and more. However, it also raised concerns about automation’s impact on employment and privacy, leaving us with a mixed legacy.

The promise of the Fifth Industrial Revolution.

The Fifth Industrial Revolution represents a quantum leap forward. At its core, it combines AI, advanced biotechnology, nanotechnology, and quantum computing to usher in a new era of possibilities. One of its most compelling promises is the extension of human life. With breakthroughs in genetic engineering, regenerative medicine, and AI-driven healthcare, we are inching closer to not just treating diseases but preventing them altogether. It’s a vision where aging is not an inevitability, but a challenge to overcome.

A new method to develop recyclable, organic and flexible electronics

Posted by in categories: biotech/medical, wearables

The electronics industry has been in continuous development over the past decades, leading to the development, fabrication and sale of a broad range of consumer devices. In recent years, many engineers have been focusing their efforts on flexible electronics that can be used to create wearable devices, such as smartwatches, earbuds, fitness trackers, and even smart jewelry, and electronic implants for medical applications.

While significant progress has been made towards the development of , the widespread commercialization of a growing number of electronics has raised significant concerns related to their sustainability. Some research teams have thus been trying to identify environmentally-friendly materials and fabrication strategies, which could mitigate the adverse impact of the electronics industry on the planet.

Researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea recently introduced a new method to create organic and flexible electronic devices with recyclable components. This method, outlined in a paper in Nature Electronics, relies on reusable materials and eco-friendly solvents that have a minimal impact on the environment.

Using electricity, scientists find promising new method of boosting chemical reactions

Posted by in categories: biotech/medical, chemistry

Electricity could be used to enhance a specific chemical reaction in the synthesis of prospective medicinal drugs.


As the world moves away from gas towards electricity as a greener power source, the to-do list goes beyond cars. The vast global manufacturing network that makes everything from our batteries to our fertilizers needs to flip the switch, too.

A study from UChicago chemists found a way to use electricity to boost a type of chemical reaction often used in synthesizing new candidates for pharmaceutical drugs.

Volume of gray brain matter significantly lower in people with early onset psychosis, finds study

Posted by in categories: biotech/medical, neuroscience

New research from the Institute of Psychiatry, Psychology & Neuroscience has found an association between a reduction in gray matter in the brain and early onset psychosis (EOP).

The study, published in Molecular Psychiatry, is the largest ever imaging study in EOP and has provided unprecedented levels of detail about the illness. It shows that in contrast to other mental health disorders, people with EOP have a reduced volume of across nearly all regions of their brain. Researchers hope that this detailed mapping could be used to assist in future diagnosis, as well as to track the effects of treatment in patients with EOP.

EOP occurs before the age of 18 during a critical period of development in the brain. Individuals diagnosed with the illness are likely to experience severe and long-lasting symptoms that respond less well to treatment. Despite this, research into EOP has been limited in sample size and statistical power.

Light-emitting textiles for diverse flexible and wearable displays

Posted by in categories: biotech/medical, engineering, wearables

Textile research has highlighted the advances in electroluminescent threads as suitable biomaterials for driving growth in the wearable electronics market. While the direct embroidery of textiles with custom designs and patterns can offer substantial benefits, machine embroidery can challenge the integrity of these threads.

In a new report of applied science and engineering published in Science Advances, Seungse Cho and a team of scientists in and medicine in the U.S., present embroiderable, multicolor, electroluminescent threads in blue, green, and yellow, that show compatibility with standard embroidery methods.

The researchers used the threads to stitch decorative designs onto a variety of consumer fabrics, without compromising their wearability or light-emitting capacity. The scientists illuminated specific messages or designs on the consumer products for the purpose of developing emergency alerts on helmet liners and as physical hazard signs.
