Culture

Scientists at the University of Kent have made a significant discovery about how the vitamin content of some plants can be improved to make vegetarian and vegan diets more complete.

Vitamin B12 (known as cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient.

But now a team, led by Professor Martin Warren at the University's School of Biosciences, has proved that common garden cress can indeed take up cobalamin.

Rational behavior is not the only thing that keeps Russians from throwing away food; many food-handling practices have been shaped by socio-cultural factors, including the gastronomic trauma suffered in times of famine and scarcity. Valeria Erguneva and Darya Asaturyan from HSE University have studied some of the cultural attitudes towards food loss and waste in Russia.

Getting Rid of Leftover Food

An international study led by biochemists at the University of Liverpool has shown that the drug-molecule ebselen can correct many of the toxic characteristics of a protein that causes some cases of hereditary motor neurone disease (MND).

MND is an incurable, progressive disease that attacks the nerves controlling movement so muscles no longer work. MND affects about 5000 people in the UK at any one time and present treatment options have only a modest effect in improving the patient's quality of life.

Repeating seismic events--events that have the same frequency content and waveform shapes--may offer a glimpse at the movement of magma and volcanic gases underneath Turrialba and Poas, two well-known active volcanoes in Costa Rica.

At the 2018 SSA Annual Meeting, Rebecca Salvage of the Observatorio Vulcanologico y Sismologico de Costa Rica presented an analysis of these repeating signals from the volcanoes since July 2016.

PITTSBURGH, May 17, 2018 - Smoking tobacco from a waterpipe, also known as a hookah, accounted for over half of the tobacco smoke volume consumed by young adult hookah and cigarette smokers in the U.S., a new University of Pittsburgh School of Medicine analysis discovered.

Ann Arbor, May 17, 2018 - The US mental health system faces considerable challenges in delivering behavioral healthcare to populations in need. In a special supplement to the American Journal of Preventive Medicine, experts focus on the key issue of behavioral health human resources for which substantial investment is needed to effect change.

New research indicates that when pregnant women take certain rheumatoid arthritis (RA) drugs that may cause immunosuppression, their children do not have a marked excess risk of developing serious infections. The Arthritis & Rheumatology findings are potentially encouraging for women with RA who are or wish to become pregnant.

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have successfully generated controlled electron pulses in the attosecond range. They used optical travelling waves that are formed by laser pulses of varying wavelengths. The movements of electrons in atoms were revealed using attosecond free-electron pulses. The findings of the researchers from Erlangen have been published in the acclaimed journal Physical Review Letters (DOI: 10.1103/PhysRevLett.120.103203).

About 22 million Americans are substance dependent (illicit drugs and alcohol), which interferes with routine life and requires treatment. Yet, only 2.5 million of these Americans participate in treatment services. The severe gap between the number of people who need treatment and the number of people who seek it poses a serious public health concern.
