HIV flushed out by cancer drug

HIV can be flushed out of its hiding places in the body using a cancer drug, researchers show.

The cornerstone of treatment, anti-retroviral therapy, kills the virus in the bloodstream but leaves "HIV reservoirs" untouched.

The study, published in PLoS Pathogens, showed the drug was "highly potent" …


If telomeres are long, lung cancer risk goes up

The protective caps on DNA are called telomeres. Shortened telomeres have been implicated in aging and cardiovascular diseases, but their …


Memories of a parasite can linger in the skin

3D brain map reveals connections between cells in nano-scale

Scientists have created an unprecedented high-resolution map of the brain that reveals structures as small as those found in individual nerve cells.

They produced the 3D map from a compilation of images taken with nanoscale resolution, making it possible to pick out features measured in millionths …

Genome-wide mutational spectra analysis reveals significant cancer-specific heterogeneity


Cancer is widely recognized as a genetic disease in which somatic mutations are sequentially accumulated to drive tumor progression. Although …


Study: The kinds of friendships you have in your 20s and 30s predicts your well-being later in life

A new study shows that when it comes to friendship, it’s quantity over quality that matters in your 20s—and vice versa in your 30s.

That pattern turns out to be a predictor of psychological well-being later in life, and it happens to be one that comes relatively naturally to many of us.

A Sense Of Self: What Happens When Your Brain Says You Don't Exist

Science journalist Anil Ananthaswamy thinks a lot about "self" — not necessarily himself, but the role the brain plays in our notions of self and existence.

In his new book, The Man Who Wasn't There, Ananthaswamy examines the ways people think of themselves and how those perceptions can be distorted …

Dengue vaccine protects people nine years or older — but harms younger kids

A vaccine for dengue, a leading cause of illness and death among children in some Latin American and Asian countries, protects people nine years old and older from the infection, according to a study in the New England Journal of Medicine. There’s a catch, though: children vaccinated before age nine …


Milestone In Nigeria: One Year Polio-Free

It’s cause for excitement, but there’s more work ahead

One year ago today, health officials announced the last case of polio in Nigeria. Since then, the country has remained polio-free—one step of many toward an official certification of eradication from the World Health Organization.

As of 1988, …


New study shows yet another reason not to overuse antibiotics

Scientists have been warning for decades that we use too many antibiotics, both in people to treat relatively mild infections and in agriculture to bulk up farm animals and keep them free of disease.

The consequences, they caution, are dire—and already emerging in hospitals with bacteria that can’t …


Software To Predict Exactly What Happens When You Edit A Gene

Sifting through the tangled genetic web of precision medicine

Genetics researchers are really excited about CRISPR/Cas9, an enzyme that has made it easier than ever for scientists to target a particular strand of DNA, snip part of it out, and replace it. And though its use in humans is still in its …

'Gay genes': science is on the right track, we're born this way. Let’s deal with it.

In a recent Guardian article , Simon Copland argued that it is very unlikely people are born gay (or presumably any other sexual orientation). Scientific evidence says otherwise. It points strongly to a biological origin for our sexualities. Finding evidence for a biological basis should not scare …

Doctors are 'outraged' by the cost of cancer treatments

Recent breakthroughs in cancer treatment come with a hefty price tag.

In 2014, virtually every new cancer-treatment drug approved by the Food and Drug Administration was priced at more than $120,000 a year, according to a new study. And the cost for each additional year lived by a patient as a …


Scientists are trying to make sense of a Native American link to indigenous Australians

Two new studies published this week in Natureand Science are battling it out over the true origins of Native American ancestry.
