The PLAN has built a series of underground tunnels to protect key warships and submarines from surprise attack. A few are well known, others need careful analysis to identify.
A Nebraska college student, Katy Ayers, grew a canoe from mushroom roots with the help from a company called Nebraska Mushrooms. The canoe has the same shape as others and the ability to flow on water. To read more click here.

After 10 years, Prof. Raimar Wulkenhaar from the University of Münster’s Mathematical Institute and his colleague Dr. Erik Panzer from the University of Oxford have solved a mathematical equation which was considered to be unsolvable. The equation is to be used to find answers to questions posed by elementary particle physics. In this interview with Christina Heimken, Wulkenhaar looks back on the challenges encountered in looking for the formula for a solution and he explains why the work is not yet finished.
You worked on the solution to the equation for 10 years. What made this equation so difficult to solve?
It’s a non-linear integral equation with two variables. Such an equation is so complex that you do actually think there can’t possibly be any formula for a solution. Two variables alone are a challenge in themselves, and there are no established approaches for finding a solution for non-linear integral equations. Nevertheless, again and again during those 10 years there were glimmers of hope and as a result, and despite all the difficulties, I thought finding an explicit formula for a solution – expressed through known functions – was actually possible.
China is getting ready to build a new space station. On 5 May, the Chinese Long March 5B rocket – the same rocket that is planned to lift parts of a new space station into orbit and eventually carry astronauts to space – launched for the first time from Hainan Island.
For this test flight, the rocket carried with it an unnamed crew capsule. No astronauts were aboard this trip, but according to the China Aerospace Science and Technology Corporation it will be able to carry six people at a time, twice as many as the Shenzhou spacecraft that has been used for all the country’s other crewed missions.
After it reached orbit, Long March 5B dropped off the crew spacecraft, which will undergo a few tests in space before plunging back to Earth in the next few days. This re-entry will test the spacecraft’s heat shields, parachutes and airbags. The crew capsule is designed to be reusable and to carry astronauts to the new space station, or to the moon and beyond.
Renewable sources including solar, wind and hydropower generated more electricity than coal-based plants every single day in April, a new report says.
Analysis shared by the Institute for Energy Economics and Financial Analysis (IEFA), based on data from the U.S. Energy Information Administration (EIA), said the finding marks a major “milestone” in an energy transition that is now underway.
The move away from coal for electricity generation in the U.S. accelerated in 2020 due to lower gas prices, warmer weather and a “significant amount” of new renewable capacity being connected to the grid late last year, the report suggested.
Yes, it’s possible to rawk too hard, but it’s not possible to get any louder under water.
Statistics is a useful tool for understanding the patterns in the world around us. But our intuition often lets us down when it comes to interpreting those patterns. In this series we look at some of the common mistakes we make and how to avoid them when thinking about statistics, probability and risk.
You don’t have to wait long to see a headline proclaiming that some food or behavior is associated with either an increased or a decreased health risk, or often both. How can it be that seemingly rigorous scientific studies can produce opposite conclusions?
Nowadays, researchers can access a wealth of software packages that can readily analyze data and output the results of complex statistical tests. While these are powerful resources, they also open the door to people without a full statistical understanding to misunderstand some of the subtleties within a dataset and to draw wildly incorrect conclusions.
Algae isn’t just found in your garden pond or local river. Sometimes it explodes into vast “blooms” far out to sea, that can be the size of a small country. Such algal blooms can match even a rainforest at taking carbon out of the air. And then, in just a week or two, they are gone – sometimes consumed by viruses.
Given the scale of blooms and their vital role in both marine ecology and climate regulation we must know more about these viruses. Research conducted with our Weizmann Institute colleague Yoav Lehahn and others and published in the journal Current Biology, is the first attempt to quantify the affect of viruses on large scale algal blooms.
Algae in this context refers to tiny sea organisms known as phytoplankton which exist right at the bottom of the marine food web, providing the ultimate source of all organic matter in the sea. They do this by consuming carbon dioxide during photosynthesis, “fixing” this carbon into organic matter (themselves) in the same way trees take carbon out of the air.
Aytu BioScience announced on April 20, four days before the Trump remarks, that it has signed an exclusive licensing deal with Cedars Sanai Medical Center in Los Angeles. The center has developed and is testing a UV-A “Healight” designed to be inserted via a catheter inside the trachea to kill pathogens, including the coronavirus.
Ultraviolet, or UV, light is commonly used by physicians to treat skin iseases. Cedars-Sanai says UV-A phototherapy potentially could be employed in internal organs.
President Trump has been mocked relentlessly for suggesting that ultraviolet light could be brought “inside the body” to kill the coronavirus, but there is ongoing research to do just that.
For example, the pharmaceutical firm Aytu BioScience announced on April 20, four days before the Trump remarks, that it has signed an exclusive licensing deal with Cedars-Sinai Medical Center in Los Angeles. The center has developed and is testing a UV-A “Healight” designed to be inserted via a catheter inside the trachea to kill pathogens, including the coronavirus.
