  • Plants Under Heat Stress Must Act Surprisingly Quickly to Survive

    In new results reported in The Plant Cell, molecular biologist Elizabeth Vierling at the University of Massachusetts Amherst and colleagues in India and China report finding a crucial mechanism that plants need to recover from heat stress.

  • Study Suggests Serotonin May Worsen Tinnitus

    Millions of people suffer from the constant sensation of ringing or buzzing in the ears known as tinnitus, creating constant irritation for some and severe anxiety for others. Research by scientists at OHSU shows why a common antidepressant medication may worsen the condition.

  • Orange is the New Green: How Orange Peels Revived a Costa Rican Forest

    In the mid-1990s, 1,000 truckloads of orange peels and orange pulp were purposefully unloaded onto a barren pasture in a Costa Rican national park. Today, that area is covered in lush, vine-laden forest.

  • Largest study of its kind reveals women have superior response to esophageal cancer treatment

    Female patients with locally advanced esophageal cancer that is treated with chemotherapy and radiation therapy before surgery are more likely to have a favorable response to the treatment than male patients are, and women are less likely to experience cancer recurrence, according to a study published online today in The Annals of Thoracic Surgery.

  • Why Tiger Snakes Are on a Winner

    Australian tiger snakes have “hit the jackpot” because prey cannot evolve resistance to their venom.

  • How Continents Were Recycled

    Researchers from Germany and Switzerland have used computer simulations to analyse how plate tectonics have evolved on Earth over the last three billion years. They show that tectonic processes have changed in the course of the time, and demonstrate how those changes contributed to the formation and destruction of continents. The model reconstructs how present-day…

  • Methane Hydrate is not a Smoking Gun in the Arctic Ocean

    Clathrate (hydrate) gun hypothesis stirred quite the controversy when it was posed in 2003. It stated that methane hydrates – frozen water cages containing methane gas found below the ocean floor – can melt due to increasing ocean temperatures.

  • Once invincible superbug squashed by 'superteam' of antibiotics

    The recent discovery of E. coli carrying mcr-1 and ndm-5 — genes that make the bacterium immune to last-resort antibiotics — has left clinicians without an effective means of treatment for the superbug.But in a new study, University at Buffalo researchers have assembled a team of three antibiotics that, together, are capable of eradicating the…

  • How cytoplasm ''feels'' to a cell's components

    Under a microscope, a cell’s cytoplasm can resemble a tiny underwater version of New York’s Times Square: Thousands of proteins swarm through a cytoplasm’s watery environment, coming together and breaking apart like a cytoskeletal flash mob.Organelles such as mitochondria and lysosomes must traverse this crowded, ever-changing cytoplasmic space to deliver materials to various parts of…

  • Hidden river once flowed beneath Antarctic ice

    Antarctic researchers from Rice University have discovered one of nature’s supreme ironies: On Earth’s driest, coldest continent, where surface water rarely exists, flowing liquid water below the ice appears to play a pivotal role in determining the fate of Antarctic ice streams.The finding, which appears online this week in Nature Geoscience, follows a two-year analysis…
