How is a molecular machine assembled?

The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role in this process. An international research team shed light for the first time on the structure and function of a transition state in the synthesis of...

Hunger cues

Research by investigators at Harvard Medical School illuminates the neurobiology that underlies food attraction and how hungry mice choose to pay attention to one object in their environment over another.

Immune system, not COVID virus, may pose greatest risk to pregnant women

A team of Yale scientists decided to investigate whether the virus could be affecting placental tissue of infected expectant mothers. Their analysis found that while evidence of the virus in the placenta is rare, the placenta in infected mothers tended to exhibit a much higher level of immune system activity than those of non-infected pregnant women, they report April 22 in the journal Med.

Improving survival in pancreatic cancer

Nagoya University researchers and colleagues have uncovered a molecular pathway that enhances chemotherapy resistance in some pancreatic cancer patients. Targeting an RNA to interrupt its activity could improve patient response to therapy and increase their overall survival.

Individuals in lower-income US counties or high support for former President Trump continue to be less likely to socially distance

Using nearly a year of anonymous geolocation data from 15-17 million cell phone users in 3,037 United States counties, investigators have found that individuals with lower income per capita or greater Republican orientation were associated with significantly reduced social distancing throughout the study period from March 2020 through January 2021. Their findings are reported in the American...

More belly weight increases danger of heart disease even if BMI does not indicate obesity

Research on how obesity impacts the diagnosis, management and outcomes of heart and blood vessel disease, heart failure and arrhythmias is summarized in a new statement.Waist circumference, an indicator of abdominal obesity, should be regularly measured as it is a potential warning sign of increased cardiovascular disease risk.Interventions that lead to weight loss improve risk factors yet may not...

Nanofiltration membranes to treat industrial wastewater from heavy metals

NUST MISIS scientists together with Indian colleagues from Jain University and Sri Dharmasthala Manjunatheshwara College presented innovative membranes for the complete removal of heavy metals from industrial wastewater. The special nanostructure of zinc-modified aluminum oxide made it possible to remove arsenic and lead from water with an efficiency of 87% and 98%, respectively. The results of...
