Early human fossils found in cave are a million years older than expected

57% Center coverage: 21 sources
Fossils found at the Sterkfontein Caves in South Africa reveal nearly four million years of hominin and environmental evolution. New ages range from 3.4-3.6 million years for Member 4 of the cave. The new dates show that Australopithecus existed almost a million years prior to the appearance of Paranthropus and Homo.See the Story

Flu vaccination linked to 40% reduced risk of Alzheimer's disease

75% Center coverage: 8 sources
UTHealth Houston researchers found that flu vaccination was associated with a reduced risk for Alzheimer's disease over a four-year period. The strength of this protective effect increased with the number of years that a person received an annual flu vaccine. The study comes two years after UTHealth researchers found a possible link between the flu vaccine and reduced risk of Alzheimer's.See the Story

Pandemic saw spike in US maternal mortality, especially among Hispanic mothers

83% Center coverage: 12 sources
Maternal mortality increased by 18% in 2020, according to data from the National Center for Health Statistics. A new analysis found that the maternal death rate after the start of the COVID-19 pandemic was even higher. The study also showed that existing and new disparities emerged after the pandemic with a 40% jump among already high rates for non-Hispanic Black women.See the Story

Researchers find llama's blood could hold key to 'super-immunity' against COVID-19, other viruses

80% Center coverage: 10 sources
Immune particles found in the blood of llamas could provide strong protection against all COVID-19 variants. Researchers said that "super-immunity" molecules called nanobodies could be developed into a fast-acting, inhalable antiviral treatment or spray. llamas, as well as camels and alpacas, have different immune systems from other animals.See the Story

States with higher rate of gun ownership do not correlate with more gun murders, data show

Coverage: 6 sources
Calls have rung out across the nation demanding gun control laws in a bid to curb violent crimes such as the recent series of mass shootings. Data, however, show that in states with higher percentages of households with at least one gun, crimes are not higher than in states with strict gun laws. See the Story

The pair of Orcas deterring Great White Sharks

66% Center coverage: 6 sources
Orcas have been terrorizing the population off the coast of South Africa for five years. Great white sharks have been avoiding these areas for fear of becoming the orcas next victims. The more the Orcas frequent these sites, the longer the great white sharks stay away. The change in both top predators behavior could be related to a decline in prey populations, including fishes and sharks.See the Story

Online version of algorithm shows how biases in RNA sequences affect gene expression

100% Center coverage: 3 sources
Researchers at the University of Kentucky show how differences between tissues and cells alter gene expression without changing the underlying genetic code. A ramp sequence is part of the RNA sequence that slows translation at the beginning of the gene. Ramp sequences counterintuitively increase overall gene expression by evenly spacing the translational machinery and preventing collisions later in translation.See the Story

Scientists discover mechanism controlling spread of pancreatic cancer

Coverage: 4 sources
Scientists have shown it is possible to reverse a key process that allows pancreatic cancer cells to grow and spread around the body. These findings show that a protein called GREM1 is key to regulating the type of cells found in pancreatic cancer -- and manipulating its levels can both fuel and reverse the ability of these cells to change into a more aggressive subtype.See the Story

An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.See the Story

Proteins in the eye may predict which macular degeneration patients need life-long treatment

100% Center coverage: 3 sources
Age-related macular degeneration is the most common cause of vision loss among people age 50 and older, affecting an estimated 7.3 million individuals in the United States. Standard treatment requires monthly or twice-monthly eye injections of so-called anti-VEGF drugs that slow or stop the growth of leaky blood vessels and stave off further vision loss.See the Story

'Safety in numbers' tactic keeps Pacific salmon safe from predators

100% Center coverage: 2 sources
A new University of Washington study has found that Pacific salmon in larger groups have lower risk of being eaten by predators. For some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal. The study was published June 29 in the journal Science Advances.See the Story
