70-year-old solar mystery solved

Magnificent CME Erupts on the Sun - August 31Tokyo: Solar physicists have captured the first direct observational signatures of a solar phenomenon that has eluded the world of science for over 70 years. This new information can explain how the solar corona reaches temperatures of 1,000,000 degrees Celsius — the so called “coronal heating problem”.

Resonant absorption is a process where two different types of magnetically driven waves resonate, strengthening one of them. Researchers looked at a type of magnetic waves which can propagate through a prominence – a filamentary structure of cool, dense gas floating in the corona.

The team found that magnetically driven resonance helps heat the Sun’s atmosphere. The solar corona, the outer layer of the Sun’s atmosphere, is composed of extremely high temperature gas, known as plasma, with temperatures reaching millions of degrees Celsius. As the outer layer of the Sun, the part farthest from the core where the nuclear reactions powering the sun occur, it would logically be expected to be the coolest part of the Sun, but it is 200 times hotter than the photosphere in the layer beneath.

This contradiction, dubbed as “the coronal heating problem,” has puzzled astrophysicists ever since the temperature of the corona was first measured over 70 years ago. For this, a research team from Japan, the US and Europe led by Drs Joten Okamoto and Patrick Antolin combined high-resolution observations from JAXA’s Hinode mission and NASA’s IRIS (Interface Region Imaging Spectrograph) mission. They were able to detect and identify the observational signatures of resonant absorption.

“The work shows how the power of multiple satellites can be combined to investigate long-standing astrophysical problems and will serve as an example for other research looking for similar heating in other solar observations,” the team said.

For Millennials, Owning a Car Means More Sex

Given that emerging adults in the study belonged to a vulnerable and psychologically immature group, future studies are required in other social groups to reach a broad conclusion, the researchers noted

Millennials, please take note if you are about to own a car (or if your parents are gifting you one on New Year) as this can boost your sex life too. According to researchers, owning a car gives young adults higher self-esteem, making it a status symbol that women find attractive, and fall for them.

Having a car increased sexual desire and the probability of having action between the sheets, reported researchers from the University of Colima in Mexico.

Owning a car early in life “can act as a sexual enhancer in emerging adulthood. Women still demonstrate a clear preference for men that possess or show the potential to acquire material resources,” said study lead author David Soriano-Hernandez.

For the study, published in the journal Sexuality Research and Social Policy, the researchers asked 809 students aged 17 to 24 studying at a small university in Western Mexico about their sex lives.

The students were surveyed in relation to their sexual conduct, along with other socio-economic aspects.

The participants were then separated into two groups, one with cars and other without it.

Having a car increased sexual desire and the probability of having sexual intercourse at a younger age, of having more sexual partners, and increase in the frequency of sexual activities.

According to the researchers, having their own cars gives young men higher self-esteem and is a status symbol women find attractive.

Those with a car typically had sex twice as often, and with double the number of partners.

One drawback was that they were engaged in unsafe sex, the researchers said.

A car also makes it easier to get to places for sex and can be used at public places too, it added.

“It is not unusual for cars to have a type of erotic effect on their owners and spectators. Expressions such as ‘hot’, ‘sexy’, and ‘exciting’ are often used to describe automobiles,” Soriano-Hernandez said.

The study noted that the automobile can also act as a sexual enhancer in emerging adulthood, which should be taken into consideration in the development of sex education strategies.

Given that emerging adults in the study belonged to a vulnerable and psychologically immature group, future studies are required in other social groups to reach a broad conclusion, the researchers noted. (IANS)
