When Mark Abbott and his team pulled a 300-foot-long mud core from the bottom of a high lake in the Peruvian Andes, he hoped it could provide a glimpse into the last 160,000 years of climate change. Instead, the researchers revealed July 13 in the journal Nature, that the lake floor recorded glacier tides for more than 700,000 years – the longest glacier record for the tropics, and among the longest historical climate records, full point. In the lake’s mud, a multi-agency team found clues about how climate change could shape the modern world. “This is unlike anything we’ve had before,” said Abbott, a professor of geology and environmental sciences at the Kenneth P. Dietrich School of Arts and Sciences at the University of Pittsburgh. “We now have a land-based record of glaciation from the tropics that is in many ways the same as our record from polar ice caps and from the oceans, and it’s really lacking.” Researchers have known for decades that Lake Junin is a rare gem.

A newly discovered star is so close to the center of our galaxy’s supermassive black hole that it completes an orbit in just four years. It is the shortest orbit for any of the stars around Sagittarius A*. This is an oval-shaped journey around a black hole that takes the star to an orbital speed of more than 2.5 percent of the speed of light. This discovery adds exciting new information about the strange dynamics of the center of the Milky Way. Although the center of our galaxy is quite quiet compared to other galaxies, the environment around Sgr A* is an extreme place. Black holes are monsters, which have a mass about 4 million times the mass of the Sun. Before astronomers confirmed its existence with live images, scientists deduced its existence and calculated its mass based on the star locked in orbit around Sgr A*. The star, called S2, is just one of a group of stars known as S-stars, which follow a long, sharp elliptical orbit around Sgr A*, with a black hole at one end of the

Washington [US]July 9 (ANI): Researchers have entangled two quantum memories via a 33-kilometer-long fiber-optic connection, a record and an important step towards a quantum internet. A network where data transmission is highly secure against hacking? If physicists succeed, this will one day become a reality with the help of the quantum mechanical phenomenon known as entanglement. For entangled particles, the rule is: If you measure the state of one particle, you automatically know the state of the other. It makes no difference how far the particles are entangled with each other. This is the ideal state for transmitting information over long distances in a way that makes eavesdropping impossible.

Record gasoline prices cause stress for households and businesses. However, a drop in global oil prices doesn’t necessarily mean that the price you pay on bowser will drop immediately. “Over the last two weeks, we’ve actually seen oil prices drop by around $22 a barrel,” said Mark McKenzie, chief executive of the Australasian Convenience and Petroleum Marketers Association. Mark McKenzie represents gas station owners and thinks pump prices will drop in the coming weeks. ( ABC Illawarra: Sarah Moss ) “If that trend is maintained over the next few weeks and months, then we should really expect to see prices drop by a comparative margin.” Global prices for crude oil – which is then refined into gasoline and other products – have fallen about 15 percent in the past month. ( ABC News: Alistair Kroie ) However, the situation is complicated, with several factors — such as the invasion of Ukraine, refinery capacity, expensive pre-election promises, and a potential recession in the United Sta

Researchers from LMU and Saarland University have entangled two quantum memories via a 33-kilometer-long fiber-optic connection — a record and an important step towards the quantum internet.

For entangled particles, the rule is: If you measure the state of one particle, you automatically know the state of the other. It makes no difference how far the particles are entangled with each other. These are ideal circumstances for transmitting information over long distances in a way that makes eavesdropping impossible. A team led by physicist Prof. Harald Weinfurter from LMU and Prof. Christoph Becher of the University of Saarland has now combined two atomic quantum memories via a 33-kilometer-long fiber-optic link. This is the furthest distance anyone has ever managed via telecommunicati
