If you had the grooming habits of a Neanderthal, perhaps it's a good thing your nose wasn't as sensitive to urine and sweat as a modern human's.

From the tropics to the poles, from the sea surface to hundreds of feet below, the world's oceans are teeming with one of the tiniest of organisms: a type of bacteria called Prochlorococcus, which despite their minute size are collectively responsible for a sizable portion of the oceans' oxygen production. But the remarkable ability of these diminutive organisms to diversify and adapt to such...
Researchers from Rice University and St. Jude Children's Research Hospital in Memphis, Tennessee, Have taken a close look at one of the ways cells repair broken strands of DNA and discovered details that could help make a particular enzyme a promising target for precision cancer therapy.
Around 90% of the Sierra Madre, which protects the Philippines from the worst of climate change, is gone.
The vaccine targets a disease known to weaken colonies by attacking bee larvae.
Inexpensive iron salts are a key to simplifying the manufacture of essential precursors for drugs and other chemicals, according to scientists at Rice University.

indigenous dogs roamed Jamestown in the early 17th century, and out of desperation during harsh winter months, some colonists ate them, researchers have proven.
The birth of a child is a major life transition, and it can be a stressful time for new parents. Family and relationship education programs are available to help individuals and couples deal with these challenges. But do such programs work as intended?
Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood.
A chemistry collaboration has led to a creative way to put carbon dioxide to good—and even healthy—use: by incorporating it, via electrosynthesis, into a series of organic molecules that are vital to pharmaceutical development.
Although the human body is externally symmetric across the left-right axis, there are remarkable left-right asymmetries in the shape and positioning of most internal organs, including the heart, lungs, liver, stomach, and brain.
Become a Dark Energy Explorer, help map the distant universe and figure out what makes it expand faster and faster! Dark energy makes the whole universe expand faster and faster! But what causes this spectacular process? Join NASA’s newest citizen science project, Dark Energy Explorers, and help figure out this puzzle. At Dark Energy Explorers, you’ll look through images of distant...
The world’s glaciers are shrinking and disappearing faster than scientists thought, with two-thirds of them projected to melt out of existence by the end of the century at current climate change trends, according to a new study. But if the world can limit future warming to just a few more tenths of a degree and fulfill international goals — technically possible but unlikely according...
A new study now reveals that cilia in the organizer function as sensors for mechanical force exerted by flow to shape the left-right body plan of the developing embryo.
Scientists have made new projections of glacier mass loss through the century under different emissions scenarios.
Researchers describe a previously unknown component of brain anatomy that acts as both a protective barrier and platform from which immune cells surveil the brain for infection and inflammation.
Researchers are studying how the reduction of a gene variant found in the brain's immune cells could diminish the risk of late-onset Alzheimer's disease.
Scientists have discovered for the first time that invasive rats on tropical islands are affecting the territorial behavior of fish on surrounding coral reefs. The new study shows that the presence of invasive black rats on tropical islands is causing changes in the territorial behavior of the jewel damselfish -- a herbivorous species of tropical reef fish that 'farm' algae in the branches of...
Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could be used to develop a large-scale network of quantum processors that could efficiently communicate with one another.
Exactly 230 years after Capt. William Bligh's voyage on the HMS Providence, a plant biology team has traced five major lineages of Caribbean breadfruit back to that single introduction from Bligh's voyage. Three generation of women solved the centuries-old mystery.
A randomized controlled trial in 234 military personnel and veterans from four Texas locations found clinically significant reductions in PTSD symptoms in more than 60 percent of patients and long-term remission of the diagnosis in more than 50 percent after three weeks of outpatient Prolonged Exposure therapy.
Scientists have performed the largest study yet examining drug sensitivity in childhood acute lymphoblastic leukemia across genomic subtypes and its association with treatment response.
Researchers have published an assessment of 13 studies that took a genotype-first approach to patient care. This approach contrasts with the typical phenotype-first approach to clinical research, which starts with clinical findings. A genotype-first approach to patient care involves selecting patients with specific genomic variants and then studying their traits and symptoms; this finding...
A new study based on 297 ancient Scandinavian genomes analysed together with the genomic data of 16,638 present day Scandinavians resolve the complex relations between geography, ancestry, and gene flow in Scandinavia -- encompassing the Roman Age, the Viking Age and later periods. A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially...
