Alex experienced pain that stopped him from playing with other children but doctors had no answers to why. His frustrated mom asked ChatGPT for help.
Space probes that have been launched from Earth currently cannot self-determine their locations in space. To know where they are, they first need to receive signals from Earth which they then bounce back. The signals are then received back on Earth and specially designed clocks then compute the time taken for the signals to travel back. Based on the calculated time, the location of the probe is determined and then communicated back to the probe.
NASA’s Perseverance rover has successfully completed an experiment designed to create oxygen on Mars, using a technique that could one day provide astronauts with breathable air, and be used as a key ingredient in rocket fuel for a return journey home.
Humanity is looking to expand deeper into the solar system, first by establishing a permanent base on the Moon, before finally placing human boots on Mars for the first time in our species’ short history. For this to be a reality, both NASA and its partners need to develop new technologies that will make use of the natural resources of those distant worlds to ensure that future missions are as self reliant as possible.
One major problem faced by astronauts visiting Mars is ensuring they have a ready supply of breathable air. Oxygen on Earth is relatively abundant, making up roughly 21 percent of our planet’s atmosphere. However, the gasseous shell enveloping Mars is composed of less than one percent oxygen, and 96 percent carbon dioxide, with nitrogen, argon, and other myriad trace gases making up the remainder.
Obesity, characterized as an abnormally high, unhealthy amount of body fat, has become a common disease throughout the United States. Individuals with obesity often develop a variety of other health conditions, known as comorbidities, such as heart disease, high blood pressure, diabetes, and arthritis.
Obese individuals also remain at an elevated risk of some types of cancer. The risk of developing specific subtypes of breast (particularly in postmenopausal women), colorectal, endometrial, esophageal, kidney, pancreatic, and gallbladder cancers increases with obesity.
Recent medical and technological advances have led to surgical procedures that can result in significant weight loss. Bariatric surgery promotes weight loss by surgically altering the body’s digestive processes. Various types of bariatric surgery focus on different components of the digestive system. Some procedures surgically reduce the stomach size so the patient will feel full sooner and may eat less. Other strategies target the small intestine, altering how the body absorbs food and nutrients.
The science of human consciousness offers new ways of gauging machine minds – and suggests there’s no obvious reason computers can’t develop awareness.

The National Institute of Health (NIH) estimates that COPD currently affects over 15 million individuals in the US. What’s even more worrisome is that many others could have the condition but don’t know about it yet.
New research shows resistance training may help counteract skin aging even better that aerobic exercise. Here’s what to know, and how to add resistance training or weight lifting into your exercise routine to reap skin benefits.
Following your gut. Losing your appetite. A gutsy move. Though we often consider the gut as merely a digestive tool, these common expressions reflect the central role the gut plays in a much wider range of essential functions.
The entire digestive tract is lined by the enteric nervous system (ENS), a vast network of millions of neurons and glial cells—the two primary cell types also found in the central nervous system. While often called the second brain, the ENS not only generates the same neurotransmitters but actually predates the evolution of the central nervous system in the brain.
The functions of the ENS are crucial to life and extend far beyond digestion, as it regulates immunity, gut secretions, and enables complex, bi-directional communication between the gut and the brain. This is why a happy gut co-exists with a happy brain, and why digestive issues can lead to changes in mood and behavior.
As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier.
But University of Michigan researchers have discovered that the rate at which these large structures grow is slower than predicted by Einstein’s Theory of General Relativity.
They also showed that as dark energy accelerates the universe’s global expansion, the suppression of the cosmic structure growth that the researchers see in their data is even more prominent than what the theory predicts. Their results are published in Physical Review Letters.
