These are viruses called bacteriophages that infect only bacterial cells.
Bacteria are becoming resistant to even the most powerful antibiotics. These expensive, hard-to-treat infections are prompting physicians to reassess using viruses to destroy bacteria.
Standing up when doing routine things such as talking on the phone can reduce the amount of time a person sits.
Sitting has been maligned in recent years for its role in obesity and diabetes. Now, a recent study in older women suggests that sedentary behavior may also increase heart disease risk.
Genetically engineered mice are invaluable for learning about human disease.
When geneticists create mice with special traits, there is no way to be sure that they will be inherited by the offspring. But a new genetic tool called a gene drive may fix the problem.

Researchers are exploring the possibility of creating living drugs – designer microbes that can live in our guts and provide critical components that our body needs but can't make itself.
People plus machines will surpass the capabilities of either element alone.
Artificial intelligence techniques like deep learning and reinforcement learning are getting increasingly advanced and capable of helping people with a wide range of complex tasks.

El hecho de no tener gripe no significa que no estemos llenos de virus por dentro y por fuera. ¿Qué hacen todos estos virus, además de enfermarnos?
Every surface of our body – inside and out – is covered in microorganisms: bacteria, viruses, fungi and many other microscopic life forms.
Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?

This year's Nobel Prize for literature was nixed because of a sex scandal. Other Nobels have neglected key contributors. Should all prizes be cancelled while criteria for winning is reassessed?
Patient with leg ulcers.
Dangerous open wounds known as cutaneous ulcers are common in people with diabetes and bedsores. Now scientists have figured out how to reprogram the cells inside these wounds to heal themselves.
You've heard the adage, you are what you eat. But a new study suggests that you are 'when' you eat may be more accurate. Restricting eating times can keep chronic diseases at bay and ward off obesity.

New suicide data indicates that years of record bloodshed in Mexico have traumatized residents in places where the violence is most concentrated.
Ciudad Juárez, on the US-Mexico border, has suffered high levels of deadly violence for over a decade. New suicide data reveals the severe mental health impacts of living with chronic violence.
California’s San Onofre Nuclear Generating Station was shut down in 2013.
Commercial nuclear reactors provide roughly one-fifth of the electricity produced in the US. But they face grave threats to their continued operation.
What if it were a lot easier to install solar power?
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.

Electric rideables are making life less comfortable and more dangerous for pedestrians. Here's how makers of rideables could help make cities safer for everybody.
Sitting can do more than give you a headache. It is linked to diabetes and obesity.
Researchers are learning even more about how a sedentary lifestyle is bad for our bodies. A recent study shows a link between sitting patterns and diabetes in older people.
The northeast edge of the Venable Ice Shelf, near Antarctica’s Allison Peninsula.
Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
