    Thirty years after nations banded together to phase out chemicals that destroy stratospheric ozone, the gaping hole in Earth’s ultraviolet (UV) radiation shield above Antarctica is shrinking. But new findings suggest that at midlatitudes, where most people live, the ozone layer in the lower stratosphere is growing more tenuous—for reasons that scientists are struggling to fathom.

    “I don’t want people to panic or get overly worried,” says William Ball, an atmospheric physicist at the Physikalisch-Meteorologisches Observatorium Davos World Radiation Centre in Switzerland. “But there is something happening in the lower stratosphere that’s important to understand.”

    Several recent studies, including one published last month in Geophysical Research Letters, point to a robust recovery of stratospheric ozone concentrations over Antarctica—the long-awaited payoff after the Montreal Protocol in 1987 mandated a global phaseout of chlorofluorocarbons and other ozone-eating compounds.

    A landmark radio astronomy project is about to unveil its first prototype dish antenna.

    Tomorrow, researchers and engineers with the Square Kilometre Array (SKA)—to be the largest radio telescope in the world—will inaugurate the dish at a test site in Shijiazhuang, China. And they expect to erect a sister prototype in South Africa by April. But funding, technical, and bureaucratic challenges have forced planners to downsize the first phase of the SKA—envisioned to include hundreds of dishes in South Africa and thousands in Australia—and delay completion by at least 2 years, to 2026.

    Still, SKA officials are thrilled to see the first prototypes appear. “It’s great to actually see metal being deployed,” says Phil Diamond, director-general of the SKA Organisation, based in Manchester, U.K. “This is the culmination of a 5-year design program.”

  • Trump to dump controversial environmental nominee

    President Donald Trump plans to withdraw his highly controversial nominee to chair a key White House environmental panel, according to media reports.

    Kathleen Hartnett White, who had been picked to chair the White House’s Council on Environmental Quality (CEQ), came under fire from senators in both parties for what they characterized as her extremist views and disregard for science. Hundreds of scientists had also signed a letter calling on the administration to dump the nominee, who had been an environmental regulator and policy analyst in Texas.

    Hartnett White’s nomination had been in doubt since this past November, when she encountered tough questioning from both Democrats and Republicans during her confirmation hearing before the Senate Environment and Public Works Committee. 

  • New cellphone and health studies don’t eliminate uncertainty

    Two long-awaited studies of how cellphone radiation affects the health of mice and rats, released yesterday, are giving scientists plenty to think about—but the findings won’t resolve the decades-old uncertainty surrounding the issue.

    The voluminous but sometimes puzzling results also aren’t likely to prompt U.S. agencies or other bodies to immediately change how they regulate the ubiquitous devices or view their health risks.

    Questions about whether cellphones harm health have persisted for decades. The devices emit nonionizing, electromagnetic radiation of the sort that heats food in a microwave oven, but scientists have struggled to conclusively link cellphone use to cancers or other illnesses.

  • Nasty U.S. flu season continues to intensify

    Public health experts say getting a flu shot can still help protect you from this year’s unusually big outbreak.


    It’s week 10 of a flu season that may only be half over, and a wave of influenza across the entire United States has led to an alarmingly high number of sick people. Last week, 7.1% of all outpatient visits were for what’s classified as influenzalike illness (ILI), said Anne Schuchat, acting director of the U.S. Centers for Disease Control and Prevention (CDC) in Atlanta in a telephone press conference this morning. That was a jump of 0.5% from the preceding week, indicating that this year’s flu may not have peaked yet.

    In the last 15 years, only two U.S. flu seasons had a week with a higher percentage of outpatient visits for ILI, which is used as a proxy for flu because few cases are actually tested for the virus. And, Schuchat added, “We are by no means out of the woods.”

    CDC has linked the high number of cases to the spread of an influenza variant known as Type A, subtype H3N2, which is both particularly virulent and hard to stop with the flu vaccine. A Type A subtype known as H1N1 also is circulating widely, as is a Type B virus.

  • Fidel Castro’s eldest son, a physicist, is victim of apparent suicide

    Physicist Fidel Castro Díaz-Balart, the eldest son of Fidel Castro, committed suicide yesterday after undergoing months of treatment for depression, Cuba’s state media has reported. He was 68.

    Fidelito, as Castro Díaz-Balart was affectionately known in Cuba, was a prominent figure in the nation’s research scene, serving as science adviser to Cuban President Raúl Castro and as a vice president of the Cuban Academy of Sciences in Havana. “He was, in my view, a gentleman, a very modest person, and a dedicated scientist,” says geologist Manuel Iturralde, a fellow academician.

    Castro Díaz-Balart’s latest scientific project ruffled some feathers in the Cuban scientific community. In 2015, he established the Center for Advanced Studies of Cuba south of Havana that aimed to make the nation competitive in nanotechnology. The Cuban government spent millions of dollars outfitting the center with instruments—consuming the lion’s share of state funding for physics in recent years—but few scientists were willing to work at the remote site.

  • India’s premier research lab network gets cold shoulder in new budget

    NEW DELHI—When the Indian government rolled out its national budget for 2018–19 here yesterday, many researchers could breathe a sigh of relief: Most science agencies got modest but inflation-beating increases. Not the 4600 scientists at the Council of Scientific and Industrial Research (CSIR) here. The national network of 38 premier scientific laboratories is slated to receive $711.7 million, a 3.3% increase—only about half this year’s forecasted inflation rate.

    In 2015, the government sought to wean CSIR off the federal coffer, directing it to raise up to half its budget by commercializing its technologies. The council has made headway toward that target, and now funds about a quarter of its budget from outside sources. The cash-strapped labs took another hit last year, when new rules on salaries, pensions, and perks for government employees forced the council to raid its research budget for the increased personnel costs.

    “Sometimes a little tightening of the belt is good for the system,” CSIR’s Director General Girish Sahni told Science. As a result, he says, CSIR labs “have become focused.” 

  • House science committee spars over who loves the Department of Energy more

    The House Committee on Science, Space, and Technology met Tuesday to hear about management and priorities at the Department of Energy (DOE), and at first blush, the hearing could not have been more bipartisan. Both Republican and Democratic members of the committee heaped praise on DOE's basic research arm, the $5.4 billion Office of Science, and DOE's 17 national laboratories. Yet there was a current of discord, as Democrats fretted that President Donald Trump’s administration has proposed cuts to much of DOE's research portfolio.

    The committee heard testimony from Paul Dabbar, DOE's undersecretary for science, and Mark Menezes, DOE's undersecretary for energy. Committee Chairman Lamar Smith (R–TX), assured them that the committee appreciates the importance of DOE's research efforts. DOE "is a world leader in basic science research and technological development," Smith said. "Without continued investment in basic and early stage research at DOE the U.S. will lose its global technology edge."

    However, Representative Marc Veasey (D–TX) noted that in its budget proposal for fiscal 2018, which started 1 October 2017, the Trump administration called for cutting funding for research on sustainable transportation and renewable energy by 70%, research on energy efficiency by 80%, and the Office of Science by 17%. (The Washington Post reported today that the White House’s 2019 budget request, to be released 12 February, calls for cutting DOE’s renewable energy programs by 72% from current levels.

  • Update: NASA confirms amateur astronomer has discovered a lost satellite

    the IMAGE satellite

    *Update, 31 January, 11:20 a.m.: On 30 January, NASA confirmed that Tilley had discovered the revived IMAGE satellite. The NASA team was able to “read some basic housekeeping data,” the agency said, suggesting that at least the main control system is operational. Efforts to command IMAGE will likely take another week or two, as the satellite’s old control software is adapted to modern systems.

    Here is our original story from 26 January:

    After years in darkness, a NASA satellite is phoning home. 

  • In unusual move, judge grants CrossFit’s request to unmask anonymous peer reviewers

    A paper reporting injuries associated with a popular fitness regime has sparked a yearslong court battle.


    In what appears to be a first, a U.S. court is forcing a journal publisher to breach its confidentiality policy and identify an article's anonymous peer reviewers.

    The novel order, issued last month by a state judge in California, has alarmed some publishers, who fear it could deter scientists from agreeing to review draft manuscripts. Legal experts say the case, involving two warring fitness enterprises, isn't likely to unleash widespread unmasking. But some scientists are watching closely.

    The dispute revolves around a 2013 paper, since retracted, that appeared in The Journal of Strength and Conditioning Research. In the study, researchers at The Ohio State University in Columbus evaluated physical and physiological changes in several dozen volunteers who participated for 10 weeks in a training regimen developed by CrossFit Inc. of Washington, D.C. Among other results, they reported that 16% of participants dropped out because of injury.
