Food waste is a major problem in the developed world. People new to buying organic food are annoyed at how quickly it spoils but what if that wilted brown lettuce could be converted into energy?

Anaerobic digestion hasn't been done on a large scale, the numbers don't work, but academics say it could. In a numerical model. The authors looked at supply chain logistics - potential sites, transportation, production, and facility costs, as well as revenue and return on investments.

A new study is actively recruiting men and women of African ancestry who were diagnosed with prostate or breast cancer to build a database from which researchers hope to identify genetic factors that may influence cancer risk among these groups.

A decade ago surveys showed that Millennials were less concerned about environmental claims than Baby Boomers or Generation X. The reason was speculated to be environmental fatigue. Millennials saw that government recycling was only making China rich and Americans pay higher taxes, that being miserable at home while Al Gore got rich selling carbon credits made no sense, and assurances that weather were not climate during a snowstorm but were climate during a heatwave made little sense.

The discovery of new biomarkers is important for detecting ovarian cancer, as the disease is difficult to detect in its early stages where it can most easily be treated.

One approach to detecting cancer is to look for extracellular vesicles (EVs), especially small proteins released from the tumor called exosomes. As these proteins are found outside the cancer cell, they can be isolated from body fluids, such as blood, urine, and saliva. However, the use of these biomarkers is hindered by the lack of reliable ones for the detection of ovarian cancer.

Everyone knows a 'day' - one rotation of Earth - is around 24 hours long and lengthening at a rate of some 1.7 milliseconds every century. Yet 2 billion years ago it was 19.5 hours and at that rate we should have days lasting 60 hours.

Yet we don't. Instead, the tidal pull of the moon was halted for over a billion years. For that, we can thank the pull of the sun. This tidal stalemate between the sun and moon has been linked to the atmosphere’s temperature and Earth’s rotational rate.

Epidemiologists looked at data from from 1999 to 2020 and noted that death rates due to poisonings, firearms, and all other injuries increased substantially in the U.S., many of them due to suicide attempts.

The demography analysis of 3,813,894 deaths collated by the National Center for Health Statistics due to non-natural causes was simplistic - age, sex, race, ethnicity, and belief about intent, then separating out criminal acts for things like gun deaths and if there was no clear intent of suicide, listing drug overdoses as accidental, while parsing motor vehicle injuries and falls as well.
