Recent gains against the burden of illness, injury, and disability and commitment to universal health coverage (UHC) are insufficient to close the enormous gaps that remain between what is achievable in human health and where global health stands today, says a new report from the National Academies of Sciences, Engineering, ...

Compared with the rest of the animal kingdom, mammals have the biggest brains and produce some of the smallest litters of offspring. A newly described fossil of an extinct mammal relative — and her 38 babies — is among the best evidence that a key development in the evolution of ... Read More »

The adult mammalian body has an incredible ability to heal itself in response to injury. Yet, injuries to the spinal cord lead to devastating conditions, since severed nerve fibers fail to regenerate in the central nervous system. Consequently, the brain’s electrical commands about body movement no longer reach the muscles, ... Read More »

With threats of sea level rise, storm surge and other natural disasters, researchers from Florida Atlantic University’s College of Engineering and Computer Science are turning to nature to protect humans from nature. They are developing innovative ways to guard coastlines and prevent scouring and erosion from waves and storms using ... Read More »

The oceans contain large numbers of particles of biological origin, including, for example, living and dead plankton organisms and their faecal material. These so-called biogenic particles interact with each other and often form lumps, or scientifically correct aggregates, many of which sink down in the water column. In addition to ... Read More »

Climate change may have played a more important role in the extinction of Neanderthals than previously believed, according to a new study published in the journal, Proceedings of the Natural Academy of Sciences. A team of researchers from a number of European and American research institutions, including Northumbria University, Newcastle, ... Read More »

Bumblebees acquire a taste for pesticide-laced food as they become more exposed to it, a behaviour showing possible symptoms of addiction. This study of bumblebee behaviour indicates that the risk of pesticide-contaminated food entering bee colonies may be higher than previously thought, which can have impacts on colony reproductive success. ...

During their annual migration to wintering sites in Mexico, monarch butterflies encounter dangers ranging from cars and trucks to storms, droughts and predators. A study led by ecologists at the University of Georgia has found evidence that these iconic insects might be facing a new challenge. At sites along their ... Read More »

Biological anthropologists from The University of Texas at Austin have described three new species of fossil primates that were previously unknown to science. All of the new primates were residents of San Diego County at a time when southern California was filled with lush tropical forests. Since the 1930s, numerous ... Read More »

At roughly 415,000 acres, Northern California’s Mendocino Complex Fire is now the state’s largest recorded wildfire, surpassing the record held by Santa Barbara and Ventura counties’ Thomas Fire, which occurred less than a year before. Roughly 10 other large-scale conflagrations are threatening the state. And California is not yet even ... Read More »

What exactly happens when you blow on a soap film to make a bubble? Behind this simple question about a favorite childhood activity is some real science, researchers at New York University have found. In a series of experiments replicating bubble blowing, NYU’s Applied Math Lab has discovered two ways ... Read More »

One of the most intriguing questions about the human brain is also one of the most difficult for neuroscientists to answer: What sets our brains apart from those of other animals? “We really don’t understand what makes the human brain special,” said Ed Lein, Ph.D., Investigator at the Allen Institute ...

Bone marrow, the spongy tissue inside most of our bones, produces red blood cells as well as immune cells that help fight off infections and heal injuries. According to a new study of mice and humans, tiny tunnels run from skull bone marrow to the lining of the brain and ... Read More »

Levels of some persistent organic pollutants (POPs) regulated by the Stockholm Convention are decreasing in the Arctic, according to an international team of researchers who have been actively monitoring the northern regions of the globe. POPs are a diverse group of long-lived chemicals that can travel long distances from their ... Read More »

Over the past 50 years researchers, clinicians, professional organizations, and health charities have waged war on sugar, calling for dietary recommendations to be changed and for a sugar tax on soft drinks and sweet treats in an effort to reduce obesity and cardiovascular diseases. In 2014, the WHO recommended that ... Read More »

With an equator diameter of around 143,000 kilometers, Jupiter is the largest planet in the solar system and has 300 times the mass of the Earth. The formation mechanism of giant planets like Jupiter has been a hotly debated topic for several decades. Now, astrophysicists of the Swiss National Centre ... Read More »

Understanding the origin and time evolution of near-Earth asteroids (NEAs) is an issue of scientific interest and practical importance because they are potentially hazardous to the Earth. However, when and how these NEAs were formed and what they suffered during their lifetime remain enigmas. Japanese scientists, including those from Osaka ... Read More »

Kanazawa – Diamonds are adored for their dazzling beauty, often displayed in exquisite jewelry. But, this solid form of carbon is also renowned for its outstanding physical and electronic properties.
