Rare Florida sparrow could vanish this year and more birds could be at risk

The grasshopper sparrow, a tiny Florida prairie bird perched on the verge of extinction for the last decade, may have encountered a final, unconquerable foe: an invasive new disease quickly killing off its young. The disease has spread so rapidly that wildlife managers now fear another endangered sparrow, the Cape Sable seaside sparrow in the…

Scientists curb growth of cancer cells by blocking access to key nutrients

Salk researchers have discovered how to curb the growth of cancer cells by blocking the cells' access to certain nutrients. The approach, detailed in a new paper published today in Nature, took advantage of knowledge on how healthy cells use a 24-hour cycle to regulate the production of nutrients and was tested on glioblastoma brain tumors…

The Hole in Earth’s Ozone Layer Is Healing

Efforts to heal the hole in Earth's ozone layer over Antarctica appear to be paying off, according to a new, first-of-its-kind study that looked directly at ozone-destroying chemicals in the atmosphere. Earth's ozone layer protects the planet's surface from some of the sun's more harmful rays that can cause cancer and cataracts in humans, and…

New drug capsule may allow weekly HIV treatment

Researchers at MIT and Brigham and Women's Hospital have developed a capsule that can deliver a week's worth of HIV drugs in a single dose. This advance could make it much easier for patients to adhere to the strict schedule of dosing required for the drug cocktails used to fight the virus, the researchers say.…

Women survive crises better than men

Women today tend to live longer than men almost everywhere worldwide -- in some countries by more than a decade. Now, three centuries of historical records show that women don't just outlive men in normal times: They're more likely to survive even in the worst of circumstances, such as famines and epidemics, researchers report. Most…

Climate change drives collapse in marine food webs

A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine "food webs." Published in the open access journal PLOS Biology, the study's lead author PhD student, Hadayet Ullah…

CRISPR treatment prevents hearing loss in mice

Using molecular scissors wrapped in a greasy delivery package, researchers have disrupted a gene variant that leads to deafness in mice. A single treatment involving injection of a genome editing cocktail prevented progressive hearing loss in young animals that would have otherwise gone deaf, Howard Hughes Medical Institute (HHMI) Investigator David Liu and colleagues report…

Origins of photosynthesis in plants dated to 1.25 billion years ago

The world's oldest algae fossils are a billion years old, according to a new analysis by earth scientists at McGill University. Based on this finding, the researchers also estimate that the basis for photosynthesis in today's plants was set in place 1.25 billion years ago. The study, published in the journal Geology, could resolve a long-standing…
