The US born Sangeeta Bhatia at Massachusetts Institute of Technology (MIT) has developed a cheap, simple, paper test that can detect cancer. These diagnostic, which works much like a pregnancy test, could reveal within minutes, based on a urine sample, whether a person have cancer or not. The MIT media announce the major and amazing breakthrough in cancer diagonistics. These newly developed technology will allow non-communicable diseases to be detect at early stage, which will be cheap and easily accessible to the masses. For the developing world it would be exciting to adapt it instead to a paper test that could be performed on unprocessed samples in a rural setting, without the need for any specialized equipment. The simple readout could even be transmitted to a remote caregiver by a picture on a mobile phone.

The MIT professor and Howard Hughes Medical Institute investigator Sangeeta Bhatia, who is also the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science, invented a new class of synthetic biomarker, which is highly specialized instrument to do these kind of analysis. These paper test essentially relies on nanoparticles that interact with tumor proteins called proteases, each of which can trigger release of hundreds of biomarkers that are then easily detectable in a patient's urine. The MIT nanoparticles are coated with peptides (short protein fragments) targeted by different MMPs. These particles congregate at tumor sites, where MMPs cleave hundreds of peptides, which accumulate in the kidneys and are excreted in the urine.

To create the test strips, the researchers first coated nitrocellulose paper with antibodies that can capture the peptides. Once the peptides are captured, they flow along the strip and are exposed to several invisible test lines made of other antibodies specific to different tags attached to the peptides. If one of these lines becomes visible, it means the target peptide is present in the sample. The technology can also easily be modified to detect multiple types of peptides released by different types or stages of disease.

In tests in mice, the researchers were able to accurately identify colon tumors, as well as blood clots. Bhatia says these tests represent the first step toward a diagnostic device that could someday be useful in human patients. "This is a new idea — to create an excreted biomarker instead of relying on what the body gives you," she says. "To prove this approach is really going to be a useful diagnostic, the next step is to test it in patient populations."

An international team, including researchers from Google Health and Imperial College London, designed and trained a computer model on X-ray images from nearly 29,000 women.

The algorithm outperformed six radiologists in reading mammograms.

AI was still as good as two doctors working together.

Unlike humans, AI is tireless. Experts say it could improve detection. Read More: https://www.bbc.com/news/health-50857759

James Webb Space Telescope's Revelations: Since its launch, the James Webb Space Telescope has provided unprecedented insights into the cosmos, unveiling details about the early universe and distant galaxies that were previously beyond our reach.

Re-establishing Contact with Voyager 1: In a testament to human ingenuity, scientists successfully re-established communication with Voyager 1, the spacecraft launched in 1977 now traversing interstellar space, offering data from the far reaches of our solar system.

Advancements in Human Biology: The global cell atlas project released its initial findings, mapping human cells with unprecedented detail, akin to a "Google Maps for the body." Additionally, the first complete map of a fruit fly's brain was unveiled, promising new insights into neurological diseases.

Public Health Milestones: The rollout of the first malaria vaccines and the commencement of late-stage clinical trials for a new tuberculosis vaccine—the first in over a century—marked significant strides in combating these diseases. Efforts against HIV/AIDS also showed promising progress, particularly in Africa.

Weight-Loss Drugs' Expanded Potential: Medications initially developed for weight loss demonstrated potential in treating a range of other diseases, indicating a broader therapeutic application than previously anticipated.

Robotics and Quantum Computing: Technological advancements brought robots capable of performing more complex tasks and moved quantum computing closer to practical, real-world applications, heralding a new era in computing and automation.

Synthetic Biology Concerns: Leading researchers, including Nobel laureates, raised alarms about the potential risks associated with synthetic biology, particularly the creation of "mirror bacteria," underscoring the need for careful regulation in this rapidly evolving field.

Climate Change Insights: Studies indicated that global CO₂ emissions plateaued with only a 0.1% increase in 2023, suggesting a potential turning point in emission trends. However, concerns about climate tipping points, such as the Atlantic Meridional Overturning Current, highlighted the urgency for continued action.

New Antibiotic Class Discovered: A novel class of antibiotics targeting multi-drug resistant bacteria was discovered, offering hope in the fight against antibiotic-resistant infections.
