Friendship helps protect against loneliness even when oldsters do not have dementia. It can be especially beneficial for those who do.
A recent study finds that friends ought not let friends with dementia be lonely. The surprising part? Why staying friends is good for the friend without dementia as well as for the one who has it.
Students outside Columbine High School in Colorado in April 1999 following the mass shooting there. Some speculated that the shooters sought revenge for having been bullied.
Youth who are bullied may be at even higher risk than other youth for gun violence. These bullied youngsters were three times more likely to have access to a loaded gun, a recent study states.
What can a single person’s flu infection tell you about how the virus changes around the world?

Gay pride has many exuberant advocates. It also has critics in unexpected places.
In sickness and in health.

Marriage has long been tied to better health. The first study of the relationship between marriage, health and quality of life for LGBT Americans affirms the benefits of marriage – with some caveats.
A subject plays a computer game as part of a neural security experiment at the University of Washington.
BCI devices that read minds and act on intentions can change lives for the better. But they could also be put to nefarious use in the not-too-distant future. Now's the time to think about risks.
Computers may play an important role in preparing us for the next viral outbreak – whether flu or Ebola.

This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
The latest tools in synthetic biology are allowing scientists to reprogram the immune system. Many studies on immunotherapy will be presented at the world's largest cancer meeting, which starts Friday.
There’s strong support for wind power, which aids in addressing climate change, in Kansas and other red states for economic reasons.

The Trump administration has already sought to reverse several Obama-era climate change policies. Pro-environment people should now focus on threats to state climate actions.
Laboratory mice are among the first animals to have their diseases treated by CRISPR.

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
Precision editing DNA allows for some amazing applications.
Researchers are starting to harness the potential of this much-hyped gene editing technique – with coming applications in medicine, biology and agriculture.
German infantrymen aim machine guns from a trench near the Vistula River in 1916.
In the winter of 1915, a German soldier died in a field hospital in Russia. We don't know his name, but he helped revolutionize the way gay people have advocated for equality.
In sub Saharan Africa causes of death, such as suicide, have been neglected.
Understanding controversial suicide death estimates in Mozambique is challenging due to a lack of readily available data.
Capturing the moment for the internet.
Yelp and Twitter can help us spot food poisoning outbreaks quickly. But a new study shows the data favor some communities over others.
A feral dog chasing a wild boar, Banni grasslands, India.
Cats have a bad reputation as wildlife killers (deservedly so). But dogs aren't off the hook: new research shows domestic dogs have contributed to the extinction of at least 11 species.
A young girl with malaria rests in the inpatient ward of a health centre in the South Sudan.
Eliminating malaria in Africa has been held back by a range of factors, including a lack of funds and drug and insecticide resistance challenges.
Rhetoric can teach scientists how to effectively communicate what’s going on in the lab to the rest of us.
If you've only ever paired the idea of 'rhetoric' with 'empty,' think again. Rhetoricians of science have concrete techniques to share with researchers to help them communicate their scientific work.

To help feed a growing world population, restore biodiversity and slow climate change, a geologist calls for a moon shot effort to restore healthy soil around the world.
Trans-Alaska Pipeline, northern Brooks Range, Alaska.
Oil production used to fall when prices were low. But a new drilling boom in Alaska, driven by technical advances and global partnerships, spotlights America's rise as a world oil power.
Enzymes, the catalysts of biology, can engulf and break down hundreds of nerve agent molecules per second.
