California beach closes after Mexico sewage flows north

Health
The entire shoreline of a Southern California city is closed to swimmers after sewage-contaminated runoff flowed into California from Mexico's Tijuana River. The San Diego Union-Tribune reports the San Diego County Department of Environment Health issued the order Sunday, expanding the closure that has been in place for months for part of the Imperial Beach coast. Officials say more than 110 million gallons (416 million liters) of toxic storm water has flowed north from Mexico since April. The closure will be in place until testing shows the water is safe. California and the cities of Imperial Beach and Chula Vista sued the Trump administration last year over the recurring toxic flows from Mexico. The lawsuit seeks to force the U.S. government to upgrade the collection system that diverts...
By controlling exciton flows, scientists can build more efficient electronics

By controlling exciton flows, scientists can build more efficient electronics

Science
Jan. 4 (UPI) -- Scientists have found a way to control exciton flows at room temperature, paving the way for the development of faster, more efficient electronics. When an electron absorbs light, it gets bumped into a higher energy band. As quantum physics reveals, the newly energized electron leaves an "electron hole" behind. Because the high-energy electron has a negative charge and the hole has positive charge, the duo remain bound -- forming an exciton. Excitons are only found in semiconducting and insulating materials, and their unique properties can be studied in 2D materials. Physicists regularly look for new quantum properties by combing 2D materials. Recently, researchers in Switzerland layered tungsten diselenide with molybdenum diselenide, WSe2 with MoSe2, to create a new 2D me...
'We now have almost Rs 7500 cr plus monthly flows in SIPs'

'We now have almost Rs 7500 cr plus monthly flows in SIPs'

Finance
NPAs, provident fund and SIP flows together will put between Rs 1,10,000 crore and Rs 1,25,000 crore in mutual funds this year, says Nilesh Shah, MD, Kotak AMC, talking to ET Now.Edited excerpts: When the mutual fund data for March came out, it appeared that the SIP flows and the mutual fund collections were coming down. What is the update after that? Was March an aberration?March was a normal month but people who interpreted data were in aberration. They failed to understand that in equity mutual fund, there is pure equity mutual fund where we go and invest into direct equity and there are also arbitrage funds where we invest in equity and short the futures. Impact of flows in a pure equity fund and arbitrage fund is completely different. When there are flows in pure equity fund and we bu...
Evidence of water on Mars are actually grain flows, research suggests

Evidence of water on Mars are actually grain flows, research suggests

Science
Nov. 20 (UPI) -- New research undermines evidence used to suggest water still flows on present day Mars.Water was once abundant on Mars. That water is not mostly gone, but some studies have suggested Martian slopes still host the occasional flow. However, new analysis of these flow signatures suggest the dark streaks are caused by moving grains and dust.The narrow, dark lines along downward-sloping features on Mars' surface are known as Recurring Slope Lineae. Previous surveys of the lines suggest RSL expand slowly and fade after periods of inactivity. They're seasonal and become most apparent during Mars' warmer months.The lines look similar to those formed by water running down a dirt embankment on Earth, leading some scientists to believe the lines are formed by liquid water flows.But n...
