To compel people to stay at home, the current laws enforce an overnight curfew from midnight to 6 a.m. Pixabay

New lockdown measures took effect in Argentina to ensure the public continues to keep its guard up against the novel coronavirus disease (Covid-19), Argentine President Alberto Fernandez said.

However, “all measures will be insufficient if people do not become aware of the size of the problem,” Fernandez told local radio on Friday as restrictions aimed to keep people from gathering, especially at night, by closing bars and restaurants early, among other things, Xinhua news agency reported.

Argentina reported 23,683 new cases of Covid-19 on Thursday, the highest number recorded in a single day since the onset of the outbreak in March 2020.

The new rules impose a nighttime curfew from midnight to 6 a.m. to oblige people to stay at home and mandate that bars and restaurants close from 11 p.m. to 6 a.m.

According to Fernandez, the measures aim to keep people socially distanced at the moment of greatest social relaxation, which is at night, and when infections occur the most.

In the second half of April, more vaccines will arrive in the country to “speed up the rate of vaccination … which is what matters most to me, because through vaccination, (Covid-19) becomes a bearable disease for adults, it does not end people’s lives, and I am the best example of that,” the president said.

Fernandez was reported to have tested positive on April 3, but he said he has had none of the symptoms.

“The antibodies generated by the vaccine were very effective. There is no doubt that the vaccine let me ride out this contagion … without any symptoms,” he said. (IANS/KB)



When you're pregnant, the immune system is seeing the placenta for the first time in decades.

The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.

Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.

The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.

"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.

It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.

Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.

"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.

"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.
