Artificial intelligence-enhanced ECGs may speed heart failure diagnosis and treatment – BioNews Central

#artificialintelligence

When people seek emergency care for shortness of breath, a routine electrocardiogram (ECG or EKG) enhanced by artificial intelligence (AI) is better than standard blood tests at determining if the cause is heart failure, according to new research published today in Circulation: Arrhythmia and Electrophysiology, an American Heart Association journal. "Determining why someone has shortness of breath is challenging for emergency department physicians, and this AI-enabled ECG provides a rapid and effective method to screen these patients for left ventricular systolic dysfunction," said Demilade Adedinsewo, M.D., M.P.H., lead author of the study and chief fellow in the division of cardiovascular medicine at Mayo Clinic in Jacksonville, Florida. The left ventricle supplies most of the heart's pumping power, so it is larger than the other chambers and essential for normal function. In left ventricular systolic dysfunction (LVSD), the left ventricle is weakened and must work harder to maintain adequate blood flow to the body. In a typical year, about 1.2 million people go to emergency departments because they are short of breath.

Why are Artificial Intelligence systems biased?

A machine-learned AI system used to assess recidivism risks in Broward County, Fla., often gave higher risk scores to African Americans than to whites, even when the latter had criminal records. The popular sentence-completion facility in Google Mail was caught assuming that an "investor" must be a male. A celebrated natural language generator called GPT, with an uncanny ability to write polished-looking essays for any prompt, produced seemingly racist and sexist completions when given prompts about minorities.


NASA's Perseverance rover has launched: It's a stepping stone to send humans to Mars

USATODAY - Tech Top Stories

In the past few weeks, two different spacecraft have launched to the red planet and on July 30, one more was sent out. After the United Arab Emirates and China successfully launched their spacecraft to Mars earlier this month, the United States has gotten in on the action. United Launch Alliance's Atlas V rocket, equipped with NASA's Mars Perseverance rover, launched Thursday morning from Cape Canaveral Air Force Station in Florida. Perseverance would be NASA's fifth rover to reach the Martian surface. Perseverance will bring the space agency one step closer in taking humans to Mars – an initiative that's been a long time coming.


Nasa Mars rover: Perseverance robot ready to fly

BBC News

The weather in Florida is set fair for the launch of the American space agency's (Nasa) big new Mars rover. The one-tonne Perseverance robot is heading to the Red Planet to search for life and to begin the process of returning rocks to Earth for analysis. An Atlas rocket will send the vehicle on its way from Cape Canaveral Air Force Station. It'll be the third mission despatched to Mars this month, after launches by the UAE and China. Lift-off is timed for the start of a two-hour window that opens at 07:50 local time (12:50 BST; 11:50 GMT). The cruise to Mars takes seven months.


Nasa Mars launch: Space agency to head to red planet in search of alien life

The Independent - Tech

Nasa is sending a rover to Mars in the hope of finding evidence of alien life. The next-generation Perseverance rover will liftoff from Florida's Cape Canaveral before arriving at the red planet on Friday, where it look for traces of life that could once have been present on our nearest neighbour. The space agency's mission – which has cost $2.4 billion – will launch at 7.50am local eastern time, or 12.50pm in the UK. The car-sized six-wheeled robotic rover, which will launch atop an Atlas 5 rocket from the Boeing-Lockheed joint venture United Launch Alliance, also is scheduled to deploy a mini helicopter on Mars and test out equipment for future human missions to the fourth planet from the sun. The weather forecast from the Air Force's 45th Weather Squadron put chances of an undisturbed liftoff at 80 percent, reporting a slim chance that thick clouds would form over the launchpad and delay the launch.


NASA prepares to launch SUV-sized Perseverance rover to Mars

#artificialintelligence

NASA is set to launch an SUV-sized rover to Mars on Thursday, July 30 with the hopes of answering one question – is there life on the planet? The Perseverance rover will take flight aboard a United Launch Alliance Atlas V rocket at 7:50am ET from Cape Canaveral, Florida and is scheduled to arrive on the Red Planet in February 2021. The descend to Mars has been described as'seven minutes of terror,' but if the rover makes a successful landing it will travel to Jerzo Crater - a region scientist speculate was home to a lake 3.5 billion years ago. Here Perseverance will hunt for'biosignatures' of past microbial life and collect rock core samples in slender, metal tools that will be cached on the Martian surface to be retrieved in 2026 for a return trip to Earth. The prized rover is not making the journey alone, as it will be accompanied by a helicopter named Ingenuity. NASA is comparing this mission'to the Wright brothers moment,' as it will be the first time in history an aerial vehicle has flown on another world.

NASA is set to launch an ambitious mission to Mars on Thursday with the liftoff of its next-generation Perseverance rover, a six-wheeled robot tasked with deploying a mini helicopter, testing out equipment for future human missions and searching for traces of past Martian life. The $2.4 billion mission, slated for liftoff at 7:50 a.m. from Florida's Cape Canaveral, is planned as the U.S. space agency's ninth trek to the Martian surface. The United Arab Emirates and China separately this month launched probes to Mars in displays of their own technological prowess and ambition. Launching atop an Atlas 5 rocket from the Boeing-Lockheed joint venture United Launch Alliance, the car-sized Perseverance rover is expected to reach Mars next February. It is due to land at the base of an 820-foot-deep (250 meters) crater called Jezero, a former lake from 3.5 billion years ago that scientists believe could hold traces of potential past microbial Martian life.


How to Watch NASA Launch Its New Perseverance Mars Rover

WIRED

On Thursday morning, NASA is scheduled to launch its new Mars rover, Perseverance, on a six-month journey to the Red Planet. The car-sized rover will be boosted into space atop a United Launch Alliance Atlas V rocket departing from the Kennedy Space Center in Florida. It's the third and final Mars mission to depart Earth this summer; earlier in July, China and the United Arab Emirates also launched their first Martian explorers. Perseverance is essentially an alien-hunting self-driving car. It's primary mission is to find possible signs of ancient life hidden in the Martian soil and bottle them up so they can be returned to Earth by another robotic mission later this decade.
