A study conducted by Stanford researchers found nearly 10% of those tested exhibited coronavirus antibodies. The study was published in the Lancet earlier this week.The study involved dialysis patients and randomly tested over 28,000 samples. The samples were taken in July as part of the patients’ treatment.The data found stark differences based on region. The northeast around 27% of patients with coronavirus antibodies, compared to 3.5% in the west.The study’s authors stressed that the study oversampled minorities. Minorities, the study found, were considerably more likely to have coronavirus antibodies than the rest of the population.“Uncertainty exists as to whether seroprevalence estimates in the dialysis population can be extrapolated to the US population more broadly,” the study reads.The study indicated that herd immunity is still far off, as estimates say at a minimum, 50% of the US population would need to be infected to reach that level. 969

A new study takes a closer look at the impact the amount of time children spend on cell phones, computers and TV is having on their brains.“What they're finding, or what they're reporting, is that more screen time--in fact a lot of screen time, around 7 hours a day--is associated with changes in the brain and changes in cognition,” says Rachel Barr, a developmental psychologist.Dr. Barr studies the impact TVs, computers and cell phones can have on young children.Kids between the ages of 8 and 12 spend generally six hours a day, while teens are spending nearly nine hours.While Dr. Barr agrees too much time can have negative impacts, she points out what children watch on their devices matter.“Exposure to education programing in younger children is associated with better outcomes and especially for children who are growing up in low resourced communities,” Dr. Barr explains.As for what parents can do: set time limits and ground rules, like keeping screens out of the bedroom, which can make it easier for children to fall and stay asleep.“Setting up this family media plan, being mindful of your own media use and your child's media use, even though you're being bombarded by all of these changes in media yourself,” suggests Dr. Barr. 1254

A more than 4,000-year-old private tomb containing "exceptionally well-preserved" drawings has been discovered south of Cairo, according to Egypt's Ministry of Antiquities.Antiquities Minister Khaled al-Anani said the tomb had been discovered at the Saqqara archaeological site and was from the 5th dynasty of the pharaohs, which ruled roughly 4,400 years ago.The tomb belonged to a royal purification priest known as "Wahtye," al-Anani said in a statement. Inscriptions suggested the priest had served during the reign of King Nefer-Ir-Ka-Re and was the king's supervisor and inspector of the holy boat.Al-Anani said the tomb's walls were decorated with colored scenes depicting Wahtye with his mother, wife and family.The head of the excavation mission, Mostafa Waziri, said other drawings showed wine and pottery making, musical performances, sailing, hunting and the manufacture of funeral furniture.Waziri said his team had reached the tomb in November but that it had taken some time to enter as its doors were sealed.Some 50 niches inside the bomb also contained colored statues carved in rock, including of a person standing or in the scribe position, Waziri said."This statue might belong to the deceased or a member of his family," he said.The general director of the site, Sabry Farag, said the tomb was about 10 meters (33 feet) long and 3 meters (10 feet) wide, with a basement.It also contained five burial shafts, Waziri said, which will be the subject of further excavations.In November, the Antiquities Ministry announced that a mass cat cemetery and a collection of rare mummified scarab beetles were among seven tombs discovered at Saqqara.Saqqara is also home to the famous Step Pyramid. 1715
