Grandmother killer whales boost survival of calves

Science
Grandmother killer whales boost the survival rates of their grandchildren, a new study has said.The survival rates were even higher if the grandmother had already gone through the menopause.The findings shed valuable light on the mystery of the menopause, or why females of some species live long after they lose the ability to reproduce.Only five known animals experience it: killer whales, short-finned pilot whales, belugas, narwhals and humans.With humans, there is some evidence that human grandmothers aid in the survival of their children and grandchildren, a hypothesis called the "grandmother effect".These findings suggest the same effect occurs in orcas."If a grandmother dies, in the years following her death, her grand-offsp...
Study: Cancer drug may cause metabolic imbalance, shorter survival

Study: Cancer drug may cause metabolic imbalance, shorter survival

Health
Sept. 26 (UPI) -- A new study suggests that the cancer drug nivolumab, a checkpoint blocker drug, may trigger a metabolic imbalance in patients treated with the drug. This imbalance, researchers say in the study, published in the journal Nature Communications, may trigger resistance to immunotherapy agents, leading to shorter overall survival times. For the study, scientists at the Dana-Farber Cancer Institute, collaborating with the Broad Institute of MIT and Harvard, analyzed blood samples from three independent immunotherapy trials. The analysis was designed to measure changes in chemicals involved in the body's metabolic reactions. Researchers found that 78 percent of melanoma patients experienced an increase in the tryptophan to kynurenine conversion, and 26.5 percent showing increa...

Revised guidelines improve survival rates for traumatic brain injury patients

Revised guidelines improve survival rates for traumatic brain injury patients

Health
May 8 (UPI) -- People suffering severe traumatic brain injury may have a better chance of surviving when emergency medical responders follow certain guidelines before getting to the hospital, new findings show. When EMS workers focused on preventing low oxygen, low blood pressure and hyperventilation, survival rates for severe TBI patients doubled, according to research published Wednesday in JAMA Surgery. Survival rates tripled for people with TBI when EMS workers inserted breathing tubes, the researchers say. "This demonstrates the significance of conducting studies in real-world settings and brings a strong evidence base to the guidelines," Patrick Bellgowan, program director at National Institute of Neurological Disorders and Stroke, said in a news release. "It suggests we can systema...

Tesla to shut stores and sell cars for cheaper as it battles for survival

Technology
Tesla is set to close all of its stores in a cost-cutting measure so it can sell its Model 3 for a reduced starting price of $ 35,000 (£26,400).The California-based firm's cars will now only be available online. Tesla's chief executive officer Elon Musk has said sales of the Model 3, which had been priced at $ 42,900 (£32,369), are essential to the company's survival.Reflecting on the store closures, Mr Musk said: "It's 2019. People want to buy online."The entrepreneur said he believes there is demand for 500,000 Model 3s per year, but conceded: "I don't know what the demand is." He said he expects Tesla to lose money in the first quarter but is "likely" be profitable in the second. Image: Tesla's Model 3 can travel 220 ...
