Rice University engineers adapt 2D ‘sandwich’ for surface-enhanced Raman spectroscopy.
A sandwich of molybdenum, sulfur, and selenium turns out to be deliciously useful for detecting biomolecules.
Tests at Rice University’s Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of biomolecules via surface-enhanced Raman spectroscopy (SERS).
Since the dawn of the Space Age, the planet Mars has been the focus of two ambitious projects. One is the search for life forms native to the planet; the other is human colonization.
To quote eminent scientist Tyler Durden: “On a long enough timeline, the survival rate for everyone drops to zero.” Actually… not necessarily true. If the quantum multiverse is real there may be a version of you that lives forever.
The stem cell treatment is derived from human placentas and is being developed by New Jersey biotech company Celularity. The early-stage trial will include up to 86 coronavirus patients with symptoms who will receive infusions of the stem cell therapy to assess the its safety and whether it prevents the patients from developing more severe illness, The New York Times.
The stem cells from the placenta used in this treatment are “natural killer” cells that guard a developing fetus or newborn from viruses in the mother. Celularity has been testing this treatment approach in cancer patients.
Initial results from the early trial are expected 30 to 60 days after the first patients receive their dose, Dr. Robert Hariri, Celularity’s founder and chief executive, told The Times.

The HPC Scout Pro electric bicycle, which can hit 45 mph (72 km/h), doesn’t fit neatly into any of the standard electric bicycle classes.
Class 1 and 2 e-bikes can reach speeds of 20 mph (32 km/h) while Class 3 e-bikes reach 28 mph (45 km/h). I used to think Class 3 e-bikes were fast. Now I think the system needs more classes.
The first possibility is called ram pressure stripping, a process through which all of the gas that a galaxy would use to form stars is vacuumed away by nearby intergalactic plasma. The other is that the environment inside a galactic cluster simply becomes too hot for cosmic gases to cool and condense into stars, rendering it useless as fuel.
“When you remove the fuel for star formation, you effectively kill the galaxy,” Brown writes, “turning it into a dead object in which no new stars are formed.”
US President Barack Obama called the Ebola outbreak in West Africa a threat to global security on Tuesday and broadly expanded the US response by ordering thousands of troops to the region along with an aggressive effort to train health care workers and build treatment centres. He called on other countries to quickly provide more helpers, supplies and money. “If the outbreak is not stopped now, we could be looking at hundreds of thousands of people affected, with profound economic, political and security implications for all of us,” Obama declared after briefings at the Centers for Disease Control and Prevention in Atlanta. Obama acted under pressure from regional leaders and international aid organisations who pleaded for a heightened US role in confronting the deadly virus, especially in the hardest-hit countries of Liberia, Sierra Leone and Guinea. “In West Africa, Ebola is now an epidemic,” Obama said. “It’s spiralling out of control, it is getting worse.“ The stepped-up US response includes sending 3,000 troops to the region, including medics and corpsmen for treatment and training, engineers to help build treatment facilities and logistics specialists to assist in patient transportation. Obama also announced that Major General Darryl Williams, head of US Army Africa, will head a military command centre based in Liberia. The announcement came the same day the World Health Organisation warned that the number of West African Ebola cases could begin doubling every three weeks and that the crisis could end up costing nearly 1 billion US Dollars to contain. Nearly 5,000 people have become ill from Ebola in Liberia, Sierra Leone, Guinea, Nigeria and Senegal since it was first recognised in March. The World Health Organisation says it anticipates the figure could rise to more than 20,000. Obama described task ahead as “daunting” but said what gives him hope is that “the world knows how to fight this disease.“ You can license this story through AP Archive: http://www.aparchive.com/metadata/youtube/045def289101ceb2e47170324839d408 Find out more about AP Archive: http://www.aparchive.com/HowWeWork
‘If we wait for a pandemic to appear, it will be too late to prepare’ — George W. Bush warned about getting ahead of something like COVID-19 way back in 2005. » Subscribe to NowThis: http://go.nowth.is/News_Subscribe » Sign up for our newsletter KnowThis to get the biggest stories of the day delivered straight to your inbox: https://go.nowth.is/KnowThis
In US news and current events today, listen to Pres. Bush urgently stress the importance of being prepared for a pandemic back in 2005. In this clip, Pres. George W. Bush addressed the Nat’l Institutes of Health about having a game plan to fight future pandemics. Pres. Bush was reportedly alarmed after reading a history book about the 1918 flu pandemic where millions had died. Out of that interest came a grand outline for future administrations to follow in response to a global pandemic.
