Smiley Face in US Sky: What is this rare celestial event, when will it appear, and what is best time and place to watch
crescent moon
will appear with two bright stars,
Castor
and
Pollux
, forming a pattern that looks like a smiley face. The event will take place in the western sky shortly after sunset.
When will Smiley Face Appear?
The moon will appear around 45 minutes after the sun sets. At that time, the sky will begin to darken. This will make bright celestial bodies easier to see. The moon will be a thin crescent, positioned about 20 degrees above the horizon. It will form the 'smiley face' shape in the sky.
Above the moon, the stars Castor and Pollux will be visible. They will appear roughly 5 degrees above the moon. Castor will be on the right, and Pollux on the left. Together with the crescent moon, they will create a pattern that looks like a face with a lopsided smile.

Ananth Tech to offer Satcom via desi satellites
New Delhi: In a first, a private Indian company is set to offer satcom services through a locally-made satellite to users across the country, competing with global giants Starlink, Eutelsat OneWeb, and Amazon Kuiper. Ananth Technologies, which already works with the government in the space domain, secured authorisation from space regulator Indian National Space Promotion and Authorization Centre (IN-SPACe) for starting broadband from space services from 2028. The company is looking to deploy a four-tonne geostationary (GEO) communication satellite that will offer 100 gigabits per second (Gbps) capacity to users. It is planning to invest '3,000 crore in the venture with additional investments planned based on demand. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Elegant New Scooters For Seniors In 2024: The Prices May Surprise You Mobility Scooter | Search Ads Learn More "Earlier, ISRO (Indian Space Research Organisation) used to build, launch and operate communication satellites. But after space reforms, the government has given the authorisation to Ananth Technologies to build, launch and operate the satellite," Subba Rao Pavuluri, founder and CMD of Ananth Technologies told ET. Since the company will be a satellite operator, it may launch more such satellites if the demand arises. Unlike low earth orbit (LEO) satellites, like those of Starlink, OneWeb and Amazon, located 400-2,000 km from Earth's orbit, GEO satellites are placed at over 35,000 km. LEO satellites have an orbital period of 1-2 hours while that of GEO satellites is 24 hours, making the latter appear stationary as they orbit at the same rate of the Earth's rotation. Live Events Latency for GEO satellites is also higher as compared to LEO, making them the latter the preferred choice for high-speed broadband from space, say experts. However, GEO satellites have better territorial coverage and just one satellite can be enough to cover India, unlike LEO satellites, which need a constellation to offer connectivity. The government is encouraging homegrown companies to enter the nascent but growing domestic satcom market. The market currently lacks private sector participation with ISRO catering solely to connectivity needs.

Hydroxyapatite is useful in medical implants because it is naturally found in the body. It is not usually rejected by the immune system. However, producing it in the lab is often costly and may involve toxic chemicals. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Llegan a RD cursos gratuitos para aprender a invertir en la bolsa de valores Clases de Economía Undo Also Read: Is Starbucks open or closed today on 4th of July? Check timings of stores on US Independence Day What Makes Human Urine Transformation Happen? Scientists used a yeast species called Saccharomyces boulardii. This yeast is usually found on the skin of tropical fruits and is used as a probiotic. Live Events The team genetically altered the yeast to break down urea from urine. Urea is a waste product formed when the body breaks down protein. The yeast, now called "osteoyeast," can turn the urea into hydroxyapatite. One liter of urine can produce about one gram of the mineral. This conversion happens in less than one day. Environmental and Commercial Benefits According to co-author David Kisailus from the University of California, Irvine, the process solves two problems. It removes urine from wastewater, helping the environment. It also creates a useful material. Hydroxyapatite made this way can be used in bone and dental implants. It may also serve other industries. These include archaeological restoration, biodegradable plastic alternatives, and construction materials. Also Read: NYT Mini Crossword Hints Today, July 4 2025: Answers, clues and tips to help save your winning streak Scalable and Low-Cost Production The process is simple and does not need advanced infrastructure. The yeast grows at low temperatures in large vats, similar to beer fermentation. This makes the method cheap and scalable. It can be used even in developing countries. The researchers are working on ways to expand the method. They want to use it to 3D print hydroxyapatite materials. These could be applied in implants, buildings, and other areas. Future Plans and Applications With the method now tested, scientists plan to scale it up. They aim to apply it in multiple industries. The team is looking into making energy-efficient, cost-effective materials that are also biodegradable. This discovery could help both the environment and industries that rely on strong, natural materials. It could also open new paths for medical and manufacturing advances. FAQs How does yeast convert urine into bone mineral? Yeast breaks down urea from urine and releases hydroxyapatite, the same mineral found in human bones and teeth. What are the uses of hydroxyapatite made from urine? It can be used for implants, biodegradable plastics, archaeological restoration, and eco-friendly construction materials.

Get a younger heart with 5 everyday habits that fit easily in your lifestyle
Ageing is a natural process that affects every organ in the body, including the heart. As people grow older, the heart often becomes less efficient, increasing the risk of cardiovascular disease . However, recent research suggests that this decline may not be entirely unavoidable. A new study has found that certain lifestyle choices, combined with new scientific understanding, could play a role in keeping the heart biologically younger for longer. In a study published in Nature Materials, researchers from the Mechanobiology Institute in Singapore have uncovered a surprising factor in heart ageing: the extracellular matrix (ECM). This structural network of proteins and molecules surrounds heart muscle cells (cardiomyocytes) and helps maintain tissue integrity, transmit signals, and support cell repair. Over time, the ECM becomes stiffer and loses elasticity, which can negatively affect heart cell function. Until now, most heart ageing research focused on what happens inside the cells. This study shifts attention to the ECM and how its condition may drive cellular ageing from the outside. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Join new Free to Play WWII MMO War Thunder War Thunder Play Now Undo Reversing Heart Ageing Through Cellular Environment To test the relationship between heart cells and the ECM, researchers created a lab model known as DECIPHER. This system allowed them to grow heart cells within environments that mimicked either young or old ECM. The results were significant. Young heart cells placed in an aged ECM environment began to behave like old cells, showing reduced performance and flexibility. Meanwhile, older cells placed in a young ECM environment regained many functions typically seen in younger cells. These findings suggest that the environment around heart cells plays a more critical role in ageing than previously believed. Assistant Professor Jennifer Young, who led the research, noted that while most studies focus on internal cellular changes, their work highlights the importance of what lies outside the cells. This could open new possibilities for treatments that target the ECM to slow or even reverse heart ageing. 5 Lifestyle Habits That Support a Younger Heart While treatments based on ECM research are still being developed, there are practical steps individuals can take now to support heart health. These habits not only promote a healthy ECM but also reduce the risk of age-related cardiovascular decline: Stay Physically Active Engaging in at least 150 minutes of moderate aerobic exercise each week helps keep blood vessels flexible and supports ECM function. Activities like walking, cycling, or swimming, combined with strength training, are especially beneficial. Get Sufficient Sleep Aim for 7 to 9 hours of restful sleep every night. Poor sleep is linked to increased blood pressure, inflammation, and heart dysfunction—all of which contribute to cardiovascular ageing. Avoid Tobacco and Limit Alcohol Smoking and heavy alcohol consumption have a direct negative effect on heart health and ECM integrity. Steering clear of both can significantly reduce cardiovascular risks. Manage Stress Effectively Chronic stress can lead to hormonal imbalances and inflammation that affect both heart cells and their environment. Mindfulness practices, outdoor time, and relaxation techniques are valuable tools for stress reduction. Eat a Heart-Friendly Diet Nutritional patterns such as the Mediterranean or DASH diet, rich in vegetables, fruits, whole grains, and lean proteins, have been linked to reduced inflammation and better heart health. It's advisable to limit processed foods and sugary beverages.
