In 2017, scientists detected X-rays following the collision of two neutron stars
It was the first time that X-rays were observed following a gamma ray burst
The X-rays were stil observable even 2 1/2 years after the collision
Scientists offer possible explanations for the X-ray emission’s strange behavior
A team of researchers can still detect lingering X-rays from a neutron star collision that happened 1,000 days prior. The prolonged X-ray emission continues to puzzle scientists.
It was on Aug. 17, 2017, when the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo first detected gravitational waves from the merger of two neutron stars. Dubbed GW 170817, the event was observed by various telescopes from all over the world within hours of the first detection.
The initial burst was followed by a short-duration gamma ray-burst (GRB) and a slower kilonova. Nine days later, scientists detected an afterglow that was visible
Back in March, as the covid-19 pandemic took over the planet, Apple finally told users that it’s okay to use some disinfecting wipes on their iPhones. At the time, transmission risks were opaque and it was better to be safe than sorry. In the meantime, we’ve learned that saliva droplets in the air pose the clearest risk for transmitting the virus, and we may have become a little careless when it comes to being mindful of surface transmission risks.
New research from Australia’s CSIRO science agency found that under lab conditions, covid-19 was much sturdier than previously believed. The team found that when samples were tested in the dark at 68° Fahrenheit on non-porous surfaces (glass, polymer note, stainless steel, vinyl, and paper notes), infectious virus was recoverable for a whopping 28 days. That’s 11 days longer than the influenza virus survives
In some concerning news, a new study has found that COVID-19 can survive for up to 28 days on a smartphone screen. This news comes from a study in Virology Journal which has reinforced the need for regular cleaning of devices and handwashing in the fight against the disease.
Some smartphone manufactures were alert to the threat of coronavirus surviving on screens before this study released. Samsung recently patented something called ‘Antimicrobial Coating’. The thought is that the company will produce smartphone cases designed to fight the virus.
Additionally, successful tests have been conducted of UV Light-based robots designed to kill coronavirus. These have sold to a number of healthcare settings to try and help combat the disease more effectively.
The new research, however, is still quite worrying. As reported by ZDNet it underlies the importance of maintaining good hygiene habits surrounding surface and device cleaning as the virus continues
Are you still washing your hands often and cleaning your phone screen and other gadgets regularly, or has that habit slipped? With the COVID-19 virus still burning its way through the population, it’s a bad time to let good habits slide, especially given the results of a new study by Australian researchers.
The findings, published in Virology Journal, suggest that the SARS-Cov-2 virus responsible for COVID-19 can last for almost a month on glass, stainless steel, and both paper and polymer banknotes if kept at ambient temperature and humidity (20 °C and 50 percent RH).

According to the paper, “the persistence of SARS-COV-2 on glass and vinyl (both common screen and screen protector materials, suggest that touchscreen devices may provide a potential source of transmission, and should regularly be disinfected especially in multi-user environments.”
It’s no secret that smartphones have had a serious impact on digital camera sales in recent years; fewer people feel the same imperative to own compact cameras and digital SLRs as they once did. So camera makers are looking for ways to entice you to jump back into the deep end of the photography pool. Earlier this year Nikon unveiled its Z5, a great-looking entry-level full-frame mirrorless camera at a pretty attractive price. But how to get you to buy one? How about if you could try it risk-free for a month? Done and done. For a limited time, if you buy a Nikon Z5, you can try it at home for 30 days essentially for free — because if you aren’t happy with it, you can return it for a full refund.
This is all part of Nikon’s Yellow Program, designed to let you get enough hands-on time
Climate change can have profound impacts across ecosystems, but rising average temperatures are just one factor among many driving those repercussions. A new study published in late September in Global Change Biology found that nighttime temperatures are increasing at a faster rate compared to daytime temps in most land areas across the Earth. That shift can influence everything from predator-prey dynamics to plant growth.
“Climate change is already messing things up,” says Daniel Cox, an ecologist at the University of Exeter and lead author of the study. “But the 24-hour asymmetry is adding an extra dimension of complexity [for species].”
Previous analyses have found that the rising greenhouse gases in our atmosphere are not having an even effect on temperatures from day to night. But Cox says this
Stem cells are cell factories that constantly divide themselves to create new cells. Implanting stem cells in damaged organs can regenerate new tissues. Cell sheet engineering, which allows stem cells to be transplanted into damaged areas in the form of sheets made up of only cells, completely eliminates immune rejection caused by external substances and encourages tissue regeneration. A research team led by POSTECH recently succeeded in drastically reducing the harvest period of such stem cell sheets.
A joint research team comprised of Professor Dong Sung Kim and researcher Andrew Choi of POSTECH’s Department of Mechanical Engineering and Dr. InHyeok Rhyou and Dr. Ji-Ho Lee of the Department of Orthopedic Surgery at Pohang Semyung Christianity Hospital has significantly reduced the total harvest period of a stem cell sheet to two days. The nanotopography of poly(N-isopropylacrylamide) (PNIPAAm), which abruptly changes its roughness depending on temperature, allows harvesting of cell sheets that
Flipkart Big Billion Days sale is beginning from October 16 but there is only so much information we know about it. Until now. We are finally seeing Flipkart revealing deals on smartphones and other gadgets. A horde of smartphones from brands such as Samsung, Realme, Oppo, Vivo, and Xiaomi is now listed on the website. And, of course, we have the deal of the year – LG G8X for Rs 19,990 – as well.
