Machine learning predicts satisfaction in romantic relationships

Posted by in categories: health, information science, robotics/AI

The most reliable predictor of a relationship’s success is partners’ belief that the other person is fully committed, a Western University-led international research team has found.

Other in a successful include feeling close to, appreciated by, and sexually satisfied with your partner, says the study—the first-ever systematic attempt at using machine-learning algorithms to predict people’s relationship satisfaction.

“Satisfaction with has important implications for health, wellbeing and work productivity,” Western Psychology professor Samantha Joel said. “But research on predictors of relationship quality is often limited in scope and scale, and carried out separately in individual laboratories.”

Researchers Use Pencil to Draw Bioelectronic Devices on Human Skin

Posted by in categories: biotech/medical, chemistry, health

Scientists from the University of Missouri, the University of Illinois and Yale University have demonstrated that a combination of pencils and paper could be used to create on-skin bioelectronic devices that might be used to monitor personal health. They’ve fabricated and evaluated a rich variety of pencil-paper-based bioelectronic devices, ranging from biophysical sensors and sweat biochemical sensors to thermal stimulators, ambient humidity energy harvesters, and transdermal drug-delivery systems.

Artificial Intelligence Identifies Prostate Cancer With Near-Perfect Accuracy

Posted by in categories: biotech/medical, health, information science, robotics/AI

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.

Reducing Sugar Uptake Increased Cancer Cells’ Sensitivity to Chemotherapy

Posted by in categories: biotech/medical, health

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.

Mould from Chernobyl nuclear reactor tested as radiation shield on ISS

Posted by in categories: health, nuclear energy, space

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.

How About a Space Station at the Bottom of the Ocean?

Posted by in categories: health, materials

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.

NASA: Virtual Guest Mars 2020 Perseverance

Posted by in categories: biotech/medical, health, robotics/AI

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:

Statement about nCoV and our pandemic exercise

Posted by in categories: biotech/medical, health, security

🤔


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.

Invention offers new option for monitoring heart health

Posted by in categories: biotech/medical, health, nanotechnology, wearables

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.

Cuba’s Interferon alfa-2b works in treating COVID-19 in China

Posted by in categories: biotech/medical, health

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.
