Astronauts suffer decades of bone loss from months in space, study shows

Astronauts on space missions lasting longer than six months suffer decades of bone loss, much of which can be irreversible, a new study has found. The finding could pose a serious challenge for future manned missions to Mars. For missions lasting six months or more, astronauts’ exposure to the microgravity of space causes them to … Read more

Study of ancient mass extinction reveals dinosaurs took over Earth amid ice, not heat

With a lava flow in the distance, a primitive feathered theropod dinosaur carries off a mammal victim during a snowy volcanic winter caused by massive eruptions during the Triassic-Jurassic Extinction. A new study says dinosaurs survived because they were already adapted to high-latitude freezing temperatures. Credit: painting by Larry Felder Thrive in a series of … Read more

Kezar Life Sciences announces positive top-line results from the Phase 2 MISSION study evaluating zetomipzomib for the treatment of patients with lupus nephritis

11 of 17 patients (64.7%) achieves a general renal response 50% or greater reduction in urine protein to creatinine ratio (UPCR) at 6 months Six of 17 patients (35.2%) achieved a complete renal response, including a UPCR of 0.5 or less, at 6 months Zetomipzomib continues to show a favorable safety and tolerability profile when … Read more

‘Super-Earth’ may be even more habitable than our own planet, study says

Researchers say rocky exoplanets — planets outside our solar system — with primordial atmospheres dominated by hydrogen and helium, have surfaces warm enough to harbor liquid water

‘Super-Earths’ outside our solar system that are rich in hydrogen or helium may be even more habitable than our own planet, a new study suggests. Researchers say that rocky exoplanets with atmospheres dominated by hydrogen and helium have surfaces warm enough to hold liquid water. The presence of liquid water is “beneficial for life,” so … Read more

New study solves long-standing mystery of what may have caused the ice age

At the beginning of the last ice, local mountain glaciers grew and formed large ice sheets, such as here in Greenland, which covered much of present-day Canada, Siberia and northern Europe. Credit: Annie Spratt/Unsplash A new study led by researchers at the University of Arizona may have solved two mysteries that have long puzzled paleoclimate … Read more

Nearly half of Maine’s renters can’t afford rent, new study finds

Lucas Bonica of Deering Place speaks about the affordable housing development being built by Avesta Housing in downtown Portland during Wednesday’s grand opening ceremony. A new Harvard University study shows that 41.1 percent of Maine renters are rent-burdened, with nearly 20 percent of them “heavily” cost-burdened. Shawn Patrick Ouellette/Staff Photographer Rent has become unaffordable for … Read more

‘Stretching’ the continents 56 million years caused global warming, study finds

The 'stretching' of the continents 56 million years ago likely led to one of the most extreme periods of global warming in Earth's history, new research suggests.  Pictured is a false color satellite image of the Faroe Islands - one of the locations studied by scientists

The stretching of the continents 56 million years ago likely led to one of the most extreme periods of global warming in Earth’s history, new research suggests. During this time, the planet experienced a temperature rise of 5-8 °C (9-14 °F), culminating in the Paleocene-Eocene Thermal Maximum (PETM), which lasted about 170,000 years. It caused … Read more
