NVIDIA GPUs Enable Simulation of a Living Cell

Posted by in categories: chemistry, computing, genetics, particle physics

Researchers from the University of Illinois developed GPU-accelerated software to simulate a cell that metabolizes and grows like a living cell.


Every living cell contains its own bustling microcosm, with thousands of components responsible for energy production, protein building, gene transcription and more.

Scientists at the University of Illinois at Urbana-Champaign have built a 3D simulation that replicates these physical and chemical characteristics at a particle scale — creating a fully dynamic model that mimics the behavior of a living cell.

Is interstellar asteroid ‘Oumuamua a spaceship? This probe could find out

Posted by in category: space

New technology could let us study the interstellar object and determine what it is and where it came from.


In October 2017, the interstellar object ‘Oumuamua passed through our Solar System, leaving a lot of questions in its wake.

Scientists Successfully Turned Used Masks into Lithium-Ion Density Batteries

Posted by in category: biotech/medical

And they’re low-cost and disposable.

With the emergence of the COVID-19 pandemic, humans have become reliant on personal protection equipment, or PPE, more and more with each wave of infection. While single-use face masks make up a large portion of PPE around the world, not much thought has been given to the proper disposal of these products.

While these products are crucial in our fight against COVID-19, they undoubtedly take a toll on the environment, ending up in landfills and oceans, giving off toxic gases. In only 2020, 52 billion face masks were made and 1.56 billion of them ended up in our oceans. they’re low-cost and disposable.

Pew Pew: The US Navy is Really Getting into Directed-Energy Weapons

Posted by in category: energy

It plays a significant role in our lives.

From enabling us to walk around and not bump into things to developing highly advanced directed energy weapons, the electromagnetic spectrum is vitally important to many aspects of our modern lives. But, life as we know it would also not be possible if electromagnetic radiation, notably visible light, did not exist.

For most of human history we have only known (but not fully understood) a very small portion of the spectrum — namely visible light and “heat” in the form of infrared light. But, since the scientific enlightenment our knowledge of the spectrum, and applications using it, have literally revolutionized the way we live and perceive the world and the cosmos around us.

Space Collisions: Can We Avoid A Catastrophe?

Posted by in category: satellites

Called ‘e. Deorbit’, it could change everything.

Desperate times call for desperate measures. According to the European Space Agency (ESA), there are 128 million objects the size of 1 mm to 1 cm, 900,000 objects the size of 1 cm to 10 cm, and 34,000 objects greater than 10 cm currently whizzing around our planet.

The Future Of Medicine: Fighting Deadly Diseases With Smart Devices And Digital Biomarkers

Posted by in categories: biotech/medical, genetics, health, mobile phones, neuroscience

What are biomarkers? They are medical signals that can measure health in an accurate and reproducible way. Common examples include blood pressure readings, heart rate, and even genetic test results.

Modern digital devices measure several health parameters. Fitbit trackers use sensors such as accelerometers to tell how many steps we’ve taken in a day or how fast we’ve been walking. When can such novel health measures function as medical biomarkers?

Neuroscience research suggests a shared mechanism underlies both sleep disturbance and mental disorders

Posted by in categories: biotech/medical, neuroscience, nuclear energy

New research published in Human Brain Mapping provides evidence of a shared neural mechanism that underlies sleep disturbance and mental disorders in preadolescents. The findings indicate that sleep disturbance and mental health problems are both related to the connectivity between and within two important brain networks.

“I noticed the importance of sleep years ago when I read several papers about the immediate amyloid protein deposition in the brain after short-term sleep deprivation. Amyloid is neurotoxic waste in the brain and needs to be transported out by cerebrospinal fluid,” said study author Ze Wang, an associate professor of diagnostic radiology and nuclear medicine at the University of Maryland School of Medicine.

“But cerebrospinal fluid is basically static most of the time. The best time to have more cerebrospinal fluid and increased flow rate is at night when you lay down and fall asleep. It is this time that our cerebral blood flow reduces. Because our brain has a fixed size, the reduction of cerebral blood flow creates space for cerebrospinal fluid and the inhomogeneous change of blood flow creates power for cerebrospinal fluid to flow and then transport the neural waste out. This is why our brain generates two times as much cerebrospinal fluid at night than daytime.”
