Low-levels of antibiotics can produce high-levels of resistance
A new study indicates that bacteria exposed to small concentrations of antibiotics over time can become highly resistant, a finding that provides an example of how low levels of antibiotics present in many environments may potentially contribute to antibiotic resistance.

Gaza now has a toxic ‘biosphere of war’ that no one can escape
The water of Gaza highlights a toxic situation that is spiraling out of control. A combination of repeated Israeli attacks and the sealing of its borders by Israel and Egypt, have left the territory unable to process its water or waste. Every drop of water swallowed in Gaza, like every toilet flushed or antibiotic imbibed, returns to the environment in a degraded state. The result is what has been termed a toxic ecology or “biosphere of war,” of which the noxious water cycle is just one part. People may evade bombs or sniper fire, but there is no escape from the biosphere.

Most Americans favor more funding for biosecurity capabilities
A new nationwide survey of the American electorate reveals that the vast majority of Americans support increased funding to address biosecurity threats. Additionally, most Americans support their elected officials actively engaging to promote and support biosecurity.

Future of testing and treating chlorine gas attacks
As experts sort through questions around recent chemical attacks in Syria, future answers to quickly testing and treating those who may have been exposed to chlorine gas may lie in chlorinated lipids, says a scientist.

“Mad camel” disease? New prion infection raises alarm
Italian and Algerian researchers released new evidence of prion disease in three dromedary camels found in an Algerian slaughterhouse. Prion diseases can affect both humans and animals, and though inter-species transmission is rare, it can happen, as it did most famously during the bovine spongiform encephalopathy (BSE, or “mad cow”) epidemic, which started in the late 1980s in the United Kingdom.

U.S. health security preparedness improved, but some regions lagging
A national snapshot used to gauge the health of the nation’s health security and emergency preparedness found that readiness has improved significantly over the past five years, but earlier identified gaps remain, with some parts of the country lagging.

The 100th meridian, where the Great Plains begin, shifting eastward
In 1878, the American geologist and explorer John Wesley Powell drew an invisible line in the dirt—the 100th meridian west, the longitude he identified as the boundary between the humid eastern United States and the arid Western plains. Now, 140 years later, scientists that the line appears to be slowly moving eastward, due to climate change. They say it will almost certainly continue shifting in coming decades, expanding the arid climate of the western plains into what we think of as the Midwest. The implications for farming and other pursuits could be huge.

New technology removes phosphorus from manure
Excess phosphorus, primarily in runoff from land application of manure, accounts for about 66 percent of impaired conditions of U.S. rivers and has created large areas of eutrophication — dead zones — in the Chesapeake Bay and the Gulf of Mexico, where aquatic life cannot survive. Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems. Researchers have developed an innovation that could have a huge impact on water quality problems in the United States, a system capable of removing almost all phosphorus from stored livestock manure.

Anti-immigrant prejudice linked to mortality risk
One of the defining elements of the 2016 election cycle was its focus on immigration. One aspect of immigration did not figure in the discussion: When it comes to mortality, U.S.-born individuals of immigrant descent fare much worse than their foreign-born counterparts — but why?

Mimicking the human immune system to detect outbreaks faster
Our immune systems are made up of billions of white blood cells searching for signs of infections and foreign invaders, ready to raise the alarm. Sandia National Laboratories computer scientists have been working to improve the U.S. biosurveillance system that alerts authorities to disease outbreaks by mimicking the human immune system.

A new class of antibiotics to fight drug resistance
According to the World Health Organization, antibiotic resistant is one of the biggest threats to global health today and a significant contributor to longer hospital stays, higher medical costs and increased mortality. An international research team has reported the discovery of a new class of antibiotics.

CDC measures have limited spread of “nightmare” bacteria
The Centers for Disease Control and Prevention (CDC) reported yesterday (3 April) that public health laboratories identified more than 220 samples of “nightmare” bacteria containing unusual resistance genes in 2017, a finding that officials say illustrates the importance of the agency’s efforts to identify emerging drug-resistant pathogens quickly and contain them before they can spread.

Climate change could increase food insecurity risk
Weather extremes caused by climate change could raise the risk of food shortages in many countries, new research suggests. The study examined how climate change could affect the vulnerability of different countries to food insecurity – when people lack access to a sufficient quantity of affordable, nutritious food.

Funding restored to National Biodefense Analysis and Countermeasures lab
The Fort Detrick, Maryland-based National Biodefense Analysis and Countermeasures Center (NBACC) is no longer facing an immediate jeopardy. The federal omnibus spending bill, released last Wednesday evening, provided full funding for the biohazard laboratory – funding which the original administration’s budget proposal eliminated.

Better accountability needed of use of Ebola recovery funds: GAO
A review of U.S.-funded Ebola recovery projects in Guinea, Liberia, and Sierra Leone by the U.S. Government Accountability Office (GAO) released this week found that, of $1.6 billion appropriated by Congress in 2014 for U.S. Agency for International Development (USAID) in the hard-hit region, $411.6 million has been targeted to 131 specific projects. However, in tallying up the projects and their scope, the GAO found that USAID needs to do more to ensure a complete inventory of all of its Ebola recovery projects.

Vaccine Integrity Project Says New FDA Rules on COVID-19 Vaccines Show Lack of Consensus, Clarity
Sidestepping both the FDA’s own Vaccines and Related Biological Products Advisory Committee and the CDC’s Advisory Committee on Immunization Practices (ACIP), two Trump-appointed FDA leaders penned an opinion piece in the New England Journal of Medicine to announce new, more restrictive, COVID-19 vaccine recommendations. Critics say that not seeking broad input into the new policy, which would help FDA to understand its implications, feasibility, and the potential for unintended consequences, amounts to policy by proclamation.
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
“Tulsi Gabbard as US Intelligence Chief Would Undermine Efforts Against the Spread of Chemical and Biological Weapons”: Expert
The Senate, along party lines, last week confirmed Tulsi Gabbard as Director of National intelligence. One expert on biological and chemical weapons says that Gabbard’s “longstanding history of parroting Russian propaganda talking points, unfounded claims about Syria’s use of chemical weapons, and conspiracy theories all in efforts to undermine the quality of the community she now leads” make her confirmation a “national security malpractice.”
