Modified viruses deliver death to antibiotic-resistant bacteria

AMI Images/SPL Phages (green) attack a bacterium (orange). Researchers are hoping to use engineered versions of these viruses to fight antibiotic resistance. Genetically modified viruses that cause bacteria to kill themselves could be the next step in combating antibiotic-resistant infections. Several companies have engineered such viruses, called bacteriophages, to use the CRISPR gene-editing system to kill specific bacteria, according to ...

Scientists in limbo as US Supreme Court allows modified travel ban

Astrid Riecken/EPA/REX/Shutterstock Immigration lawyers offer legal assistance to travellers affected by the US travel ban at Dulles Airport in Virginia on 6 February. The US Supreme Court has reinstated a limited version of President Donald Trump’s temporary order banning travellers from six majority-Muslim countries from entering the United States. The court will hear a legal challenge to the ban in ...

Intuition harnessed in the name of particle packing

Christopher Murray/EyeEm/Getty How particles jam together has implications ranging from industry to avalanche safety. For a cognitive skill that plays such a large part in science, intuition gets a raw deal. It is often dismissed as the irrational flipside of reasoned deduction: at best a problem-solving method engineered by evolution as a ‘good enough’ tool to deal with the mundane ...

The secrets of a top salary in science

Rune Johansen/Getty Administrative duties are tied to higher salaries in European universities. Michelle Pfeiffer once said that she acts for free — “but I demand a huge salary as compensation for all the annoyance of being a public personality”. Many scientists have a similar attitude. They enjoy the process and thrill of research and would probably do it for free. ...

Air guns used in offshore oil exploration can kill tiny marine life

Christian Åslund/Greenpeace A ship operates an air-gun array while looking for oil deposits off the coast of Greenland. Powerful sound waves created during offshore surveys for oil and gas can kill microscopic animals at the base of the ocean food chain, according to a new study. And these lethal effects travel much farther than ecologists had previously assumed. Researchers fear ...

Success of gravity-wave satellite paves way for three-craft mission

Manuel Pedoussaut, 2015/ESA LISA Pathfinder — shown before being encapsulated into a rocket for launch — allowed scientists to test technology for detecting gravitational waves. Europe’s gravitational-wave hunters are celebrating. On 1 July, a satellite will wrap up its mission to test technology for the pioneering quest to measure gravitational ripples in the stillness of space. Over the past year, ...

Let science be a springboard for politics

As they make plans for Fourth of July fireworks and barbecues, many Americans also think of Thomas Jefferson penning the US Declaration of Independence. Fewer realize that Jefferson regularly corresponded with scientists of his era, such as the chemist Joseph Priestley, credited with the discovery of oxygen. Priestley also enjoyed meeting with his friend Benjamin Franklin, the American statesman and ...

Overlooked water loss in plants could throw off climate models

Errors in how scientists account for water loss from leaves may be skewing estimates of how much energy plants make through photosynthesis, according to the latest research. This in turn could jeopardize models of how individual leaves function and even of the global climate. The errors are particularly pronounced when a plant’s water supply is limited — a condition of ...

Image doctoring must be halted

Nico De Pasquale Photography/Getty Digital image manipulation is a growing problem in science. Seven years ago, a cover of The Economist showed Barack Obama, head down on a Louisiana beach in front of an oil rig — the picture of lonely despair. The image perfectly encapsulated the news magazine’s story about the massive pollution caused when BP’s Deepwater Horizon platform exploded, and ...
