FIFA suspends Senegal's Pape Gueye in transfer dispute: Coach – Times of India

DAKAR: Pape Gueye, part of the Senegal squad at the Africa Cup of Nations, has been suspended by FIFA because of a transfer dispute, his coach Aliou Cisse said Friday.
“There were problems between Watford and Marseille on a transfer. FIFA has suspended him,” said Cisse.
The 22-year-old midfielder came off the bench for Senegal in their opening game in Cameroon but did not figure in Friday’s draw with Guinea.

Can coffee protect against endometrial cancer? Here is what new study says – Times of India

Coffee gives your body an instant dose of caffeine and fills it up with energy. This is the reason why many people opt for it in the morning to fuel up a sluggish day, while many people need their cup of coffee at night to stay awake for studies or night shift.

Black coffee, which is made without using milk or sugar contains zero calories is often consumed as a pre-workout drink and is said to aid weight loss.

The long list of coffee benefits includes a lower risk of type 2 diabetes, reduced risk of stroke and even a decreased risk of Parkinson’s disease by 25%.

Watch: Powerful Solar Flare Captured By NASA's Solar Dynamics Observatory – India Times

After NASA’s Parker Probe reached extremely close to the Sun’s corona, the space agency has captured the visuals of a “significant” solar flare. Captured at 11:31 am IST on Friday, the mid-level solar flare was captured by NASA’s Solar Dynamics Observatory that keeps a close watch on the Sun.

Solar flares are bursts of energy

Powerful bursts of energy, solar flares are emitted by the Sun and can affect Earth. Solar flares have the capability to impact radio communications, electric power grids, navigation signals, and also pose risks to spacecraft and astronauts according to NASA.

 NASA has classified it as a M5.5 class solar flare. Based on its intensity, solar flares can last for mere minutes or for hours. According to National Oceanic and Atmospheric Administration, solar flares travel at the speed of light – implying that its effects on the Sun-facing side of Earth’s atmosphere are felt as soon as it bursts out.

However, the radiation poses no direct harm to humans on the Earth’s surface. The powerful flares are made out of radio waves, x-rays, and gamma rays. The explosion happens after massive amounts of solar energy stored in the Sun’s magnetic field is suddenly released.

In December, we received a glimpse of what Sun’s surrounding region looks like after NASA’s Parker Probe brushed past the star. The probe was launched in August 2019 and has spent over 990 days travelling through the solar system since then – observing space around Venus and the Sun.

It reached the Sun’s corona last year – where temperatures are as high as million Celsius.

NASA Mars Perseverance Rover: Ejecting Martian Pebbles – SciTechDaily

Before and After Perseverance Sample Tube Shake

The team has made good progress implementing the initial recovery steps outlined last week. Our first success: The upper two pebbles were ejected from the bit carousel during a test. This is great news, as these small chunks of debris are believed to be the cause of the unsuccessful transfer of the drill bit and sample tube into the carousel back on December 29. Our second success: We appear to have removed most – if not all – of the cored rock that remained in Sample Tube 261.

Here is the latest…

Pebbles in Bit Carousel

On Monday, January 17, the WATSON camera imaged the bit carousel and its pebbles – and also took images underneath the rover to establish just what was down there before any recovery strategies were applied. Later that same Martian day, we rotated the bit carousel about 75 degrees before returning it back to its original position. WATSON imaging showed the two upper pebbles were ejected during the process. Tuesday night we also received the second set of under-rover images, which show two new pebbles on the surface, indicating the ejected pebbles made it fully through bit carousel and back onto the surface of <span aria-describedby="tt" class="glossaryLink" data-cmtooltip="

Mars is the second smallest planet in our solar system and the fourth planet from the sun. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname "The Red Planet." Mars’ name comes from the Roman god of war.

Rotating Perseverance's Bit Carousel

The other two pebbles, located below the bit carousel, remain. It is interesting to note that some of the initial trials performed on our testbed here on Earth indicate that the location of the two leftover pebbles may not pose a significant problem with bit carousel operation, but we are continuing analysis and testing to confirm this.

Remaining Sample in Tube

On Saturday, January 15, the team performed an experiment using Perseverance’s rotary-percussive drill. After the robotic arm oriented the drill with Sample Tube 261’s open end angled around 9 degrees below horizontal, the rover’s drill spindle rotated and then extended. Our remarkable Mastcam-Z instrument (which has video capability previously used to document some of Ingenuity’s flights) captured the event. The imagery from the experiment shows a small amount of sample material falling out of the drill bit/sample tube. Later that same Martian day, the bit was positioned vertically over “Issole” (the rock that provided this latest core) to see if additional sample would fall out under the force of gravity. However, Mastcam-Z imaging of 261’s interior after this subsequent maneuver showed it still contained some sample.

Given that some of the sample had already been lost, the team decided it was time to return the rest of the sample to Mars and hopefully completely empty the tube to ready it for potentially another sampling attempt. On Monday, January 17, the team commanded another operation of the rotary percussive drill in an attempt to dislodge more material from the tube. With the tube’s open end still pointed towards the surface, we essentially shook the heck out of it for 208 seconds – by means of the percussive function on the drill. Mastcam-Z imagery taken after the event shows that multiple pieces of sample were dumped onto the surface. Is Tube 261 clear of rock sample? We have new Mastcam-Z images looking down the drill bit into the sample container that indicate little if any debris from the cored-rock sample remains. The sample tube has been cleared for reuse by the project.

Future Moves

The team is still reviewing the data and discussing next steps. Like all Mars missions, we’ve had some unexpected challenges. Each time, the team and our rover have risen to the occasion. We expect the same result this time – by taking incremental steps, analyzing results, and then moving on, we plan to fully resolve this challenge and get back to exploration and sampling at Jezero Crater.
