A study published today (July 27, 2020) in The Lancet Digital Health by UPMC and University of Pittsburgh researchers demonstrates the highest accuracy to date in recognizing and characterizing prostate cancer using an artificial intelligence (AI) program.

“Humans are good at recognizing anomalies, but they have their own biases or past experience,” said senior author Rajiv Dhir, M.D., M.B.A., chief pathologist and vice chair of pathology at UPMC Shadyside and professor of biomedical informatics at Pitt. “Machines are detached from the whole story. There’s definitely an element of standardizing care.”

To train the AI to recognize prostate cancer, Dhir and his colleagues provided images from more than a million parts of stained tissue slides taken from patient biopsies. Each image was labeled by expert pathologists to teach the AI how to discriminate between healthy and abnormal tissue. The algorithm was then tested on a separate set of 1,600 slides taken from 100 consecutive patients seen at UPMC for suspected prostate cancer.

People often talk about sugar intake and health 🤔

Researchers have successfully increased cancer cells’ sensitivity to chemotherapy to prevent glucose from entering the cancer cell.

Researchers at Lund University in Sweden have successfully increased cancer cells’ sensitivity to chemotherapy by preventing sugar uptake. Their study, “Targeting Glut1 In Acute Myeloid Leukemia To Overcome Cytarabine Resistance,” is published in Haematologica.

It is true that sugar feeds every cell in our body, even cancer cells. Researchers have long wondered if it would be possible to prevent glucose from entering the cancer cell and in that way increase the effect of chemotherapy.

To enable sugar molecules to enter the cancer cell through the cell membrane, the cell uses glucose transporters (GLUTs), which allow substances in and out. Researchers decided to study GLUT1 and its role in acute myeloid leukemia (AML).

A radiation-absorbing fungus found at the destroyed Chernobyl nuclear reactor has been shown to absorb harmful cosmic rays on the International Space Station, and could potentially be used to protect future Mars colonies.

Exposure to cosmic rays poses a major health risk to astronauts leaving Earth’s protective atmosphere. Shields can be made out of stainless steel and other materials, but they must be shipped from Earth, which is difficult and costly.

Jacques Cousteau’s grandson is pushing for the construction of a real-life Sealab 2021. The proposed undersea laboratory is so foreign to our idea of marine studies that it’s being likened to a space station that’s also under the ocean.

The station is named Proteus, not for the changing nature of matter (like a new uncuttable material with the same name), but for the shepherd of the sea. By placing a station 60 feet underwater around the Caribbean island of Curacao, sponsoring Northeastern University says it can reduce divers’ high amount of overhead time and reduce the danger of nitrogen-induced health effects.

We’re going back to Mars, and we’d like you to be our virtual guest on the trip. On July 30, NASA will launch the Mars 2020 Perseverance rover on a seven-month journey to the Red Planet. After landing in Jezero Crater, the robotic astrobiologist and scientist will search for signs that microbes might have lived on Mars long ago, collect soil samples to be returned to Earth on a future mission and pave the way for human exploration beyond the Moon. Perseverance will be accompanied by a helicopter called Ingenuity, the first attempt at powered flight on another world.

Because of the coronavirus pandemic and in the interest of health and safety, NASA can’t invite you to Florida to watch the launch personally. However, there are many ways you can participate virtually:

In October 2019, the Johns Hopkins Center for Health Security hosted a pandemic tabletop exercise called Event 201 with partners, the World Economic Forum and the Bill & Melinda Gates Foundation. Recently, the Center for Health Security has received questions about whether that pandemic exercise predicted the current novel coronavirus outbreak in China. To be clear, the Center for Health Security and partners did not make a prediction during our tabletop exercise. For the scenario, we modeled a fictional coronavirus pandemic, but we explicitly stated that it was not a prediction. Instead, the exercise served to highlight preparedness and response challenges that would likely arise in a very severe pandemic. We are not now predicting that the nCoV-2019 outbreak will kill 65 million people. Although our tabletop exercise included a mock novel coronavirus, the inputs we used for modeling the potential impact of that fictional virus are not similar to nCoV-2019.

An invention may turn one of the most widely used materials for biomedical applications into wearable devices to help monitor heart health.

A team from Purdue University developed self-powered wearable triboelectric nanogenerators (TENGs) with polyvinyl alcohol (PVA)-based contact layers for monitoring cardiovascular health. TENGs help conserve and turn it into power.

The Purdue team’s work is published in the journal Advanced Materials.

Among the drugs used for COVID-19 is a particularly promising Cuban compound called “Interferon alfa-2b,” which has been successfully administered to Chinese patients.

In Cuba, where precaution measures against COVID-19 have included the temporary closing of schools and the shutdown of the tourist sector, among others, authorities have called on people to stay at home while Cuban scientists are working hard to develop new biotech products to kill the lethal disease.

With a growing number of cases, the island’s healthcare infrastructure is ready to treat an expected surge of patients with a wide selection of promising drugs. “The package of drugs we are administering is based on the experience of countries hardest hit by the disease. We have considered this with our experts, while our scientists try to add new local drugs to this protocol,” said Cuban Health Minister Jose Angel Portal in a recent TV appearance.

An international team of scientists has collated all known bacterial genomes from the human gut microbiome into a single large database, allowing researchers to explore the links between bacterial genes and proteins, and their effects on human health.

This project was led by EMBL’s European Bioinformatics Institute (EMBL-EBI) and included collaborators from the Wellcome Sanger Institute, the University of Trento, the Gladstone Institutes, and the US Department of Energy Joint Genome Institute. Their work has been published in Nature Biotechnology.

Imagine if this very cheap thing could treat coronavirus 🤔

That would put a wrench in profiteers plans:

Green coffee bean extract is a popular weight loss and health supplement, but does it work, and is it safe?

Green coffee beans, or raw coffee beans, are coffee beans that are not roasted. Green coffee bean extract is a popular weight loss supplement.

Some research also suggests that green coffee bean extract could have health benefits, such as improving blood pressure and cholesterol levels. This belief stems from the antioxidant properties and other pharmacologically active compounds in the unroasted beans.

This article provides a review of green coffee bean extract, a popular weight loss, and health supplement. It looks at the health benefits, research, risks, and dosage.
