Antarctica’s fourth largest ice shelf, the Larsen C Ice Shelf located on the Antarctic Peninsula, risks collapse due to mountain winds, according to a recent presentation at annual meeting of the European Geophysical Union.

The ClinicalTrials.gov data bank, managed by the National Institutes of Health (NIH)/National Library of Medicine, requires trial sponsors to register applicable clinical trials within 21 days after the first human subject is enrolled and submit certain summary results information for those trials, generally no later than one year after the study’s completion date unless a deadline extension is obtained.

Thanks to cosmic rays that created radioactive isotopes while it was in space, an asteroid on an impact trajectory with Earth On June 2, 2018 was detected before it arrived. Thanks to the isotopes in those fragments, researchers determined that 2018 LA, called such by the University of Arizona's Catalina Sky Survey as part of NASA's Planetary Defense program, was a solid rock about 1.5 m in size, which reflected about 25 percent of sunlight.Eight hours later, a video camera in South Africa recorded a bright fireball over Botswana and the hunt was on for surviving meteorites deep inside the Central Kalahari Game Reserve. The first meteorite they found 18 grams and about 3 cm in size.

Antibiotics won't help with COVID-19 because the disease is not caused by bacteria but instead a virus. However, a new study finds that some antibiotics can prevent the entry of the SARS-CoV-2 virus into cells. The Drug Design and Molecular Topology Unit group of the University of Valencia found that certain macrolide antibiotics like clarithromycin and azithromycin (used in respiratory tract infections) does just that.

As a child, you probably thought a week took forever and parents certainly thought days crept by after having an infant."Time flies when you are having fun" and COVID-19 quarantines and lockdowns were not fun.A new study also finds what psychologists warned about; the effects on those with depression issues could be even worse. Unlike a new job or moving to a new place, where time also 'seems' to slow down, the new paper found that distortions to the passage of time were also present later into the global pandemic.

On April 24th, 1990, the Hubble Space Telescope was launched, and though it had bumpy childhood once the problems were fixed it has well exceeded its mission expectancy. A good thing too. The James Webb Space Telescope that was supposed to replace it 13 years and billions of dollars ago still hasn't launched, and when it eventually does, if things don't work, no space shuttle can reach it.

The Red Sea is about 1000 miles long and at most just over 170 miles wide. The Greeks called it a sea but they also called the Persian Gulf a sea.It may instead be an ocean, because an ocean basin exists between Africa and the Arabian Peninsula. The Greeks did not know that and the problem in knowing now is that the oceanic crust along the narrow, north-south aligned rift is widely buried under a thick blanket of salt and sediments, which complicates direct investigations.

In 1946, with World War II over, archaeologists got back to work and over 10 years found discarded Hebrew Bible manuscripts in 12 Ein Feshkha Caves near the Dead Sea in the West Bank. Fragments o these "Dead Sea Scrolls" include the Apocrypha, except for the Book of Esther, which may not have survived over time.No one knows who printed most older works, for the Christian Bible it was anonymous monks, and the Dead Sea Scrolls also contain no attribution, but there has been speculation about who may have written them. Some sought to at least connect them by handwriting.

In 2019, Christiansburg, Virginia's 22,000 residents became the first place in the U.S. to have a residential drone delivery service.Yellow-winged drones with small cardboard boxes owned by Wing, a company owned by Alphabet (basically, Google) are now one of numerous trial services operating today. But regulations for giant planes full of fuel are not ready for delivery of the future, and the only way to make government get ready is public interest. Without proactive guidelines, the public will be stuck with activists doing to drones what they did to agriculture and cell phones.

At the end of the 17th century, Sir Isaac Newton scientifically showed the motion of the planets around the sun through a law of universal gravitation. He also explained the motion of the moon. Yet since both the earth and the sun determine the motion of the moon, Newton became interested in predicting the motion of three bodies moving in space under the influence of their mutual gravitational attraction, a problem that later became known as “the three-body problem”.  He did not succeed in creating a a general mathematical solution for it. The three-body problem was easy to define, yet difficult to solve. There is extreme sensitivity to the bodies’ initial positions and velocities - chaos. And chaos is hard to predict.

In western nations, there is a great deal of interest in improving standardized test scores compared to Asian students, but few schools want to do what Asian schools do most; teach to the test and teach by rote.Instead, programs focus on increasing things like 'motivation' have become popular. And so we get a mashup of math and basketball. Should we call it mathketball?A group of Copenhagen schools placed 756 1st through 5th graders in a six-week program that they found had a positive effect on their desire to learn more, provided them with an experience of increased self-determination and grew math confidence among youth. 

Just like people, trees can die of thirst, especially during a drought, but a recent field study found that a rapid collapse in the hydraulic system of trees is happening more rapidly than previously thought.The heatwave of summer 2018 was exceptional and that can be hard on trees but it was an opportunity for researchers at the University of Basel to closely study the reaction of trees to this weather phenomenon. In 2018, the Norway spruce suffered most as a result of the drought. It is the most important conifer both in Switzerland and in central Europe. The results of the study are representative of northern Switzerland as a whole, and can also be applied to other conifer species.
