Proteins that predict future dementia, Alzheimer’s risk, identified: Large study of plasma proteins and dementia illuminates the biology of dementia and may help lead to treatments

|

The development of dementia, often from Alzheimer’s disease, late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study led by researchers at the Johns Hopkins Bloomberg School … Read More

New evidence of how and when the Milky Way came together: Aging individual stars helped date an early merger event

|

New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy. Using relatively new methods in astronomy, the researchers were able to identify the … Read More

Rare COVID-19 response in children explained

|

One of the enduring mysteries of the COVID-19 pandemic is why most children tend to experience fewer symptoms than adults after infection with the coronavirus. The immune system response that occurs in the rare cases in which children experience life-threatening … Read More

Harvesting light like nature does: Synthesizing a new class of bio-inspired, light-capturing nanomaterials

|

Inspired by nature, researchers at Pacific Northwest National Laboratory (PNNL), along with collaborators from Washington State University, created a novel material capable of capturing light energy. This material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics … Read More

Mammals can use their intestines to breathe

|

Rodents and pigs share with certain aquatic organisms the ability to use their intestines for respiration, finds a study publishing May 14th in the journal Med. The researchers demonstrated that the delivery of oxygen gas or oxygenated liquid through the … Read More

The cerebellum may have played an important role in the evolution of the human brain: Study compares epigenetic modifications to DNA in the cerebellum of humans, chimpanzees and monkeys

|

The cerebellum — a part of the brain once recognized mainly for its role in coordinating movement — underwent evolutionary changes that may have contributed to human culture, language and tool use. This new finding appears in a study by … Read More

Sharks use Earth’s magnetic fields to guide them like a map

|

Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first … Read More

Earliest evidence of humans changing ecosystems with fire

|

Mastery of fire has given humans dominance over the natural world. A Yale-led study provides the earliest evidence to date of ancient humans significantly altering entire ecosystems with flames. The study, published on May 5 in the journal Science Advances, … Read More

Bats know the speed of sound from birth, scientists discovery

|

A new Tel Aviv University study has revealed, for the first time, that bats know the speed of sound from birth. In order to prove this, the researchers raised bats from the time of their birth in a helium-enriched environment … Read More

Lightning and subvisible discharges produce molecules that clean the atmosphere

|

Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be … Read More

Was North America populated by ‘stepping stone’ migration across Bering Sea?

|

For thousands of years during the last ice age, generations of maritime migrants paddled skin boats eastward across shallow ocean waters from Asia to present-day Alaska. They voyaged from island to island and ultimately to shore, surviving on bountiful seaweeds, … Read More

Global glacier retreat has accelerated: New study analyzes roughly 220,000 glaciers

|

An international research team including scientists from ETH Zurich has shown that almost all the world’s glaciers are becoming thinner and losing mass’ and that these changes are picking up pace. The team’s analysis is the most comprehensive and accurate … Read More

Mammals evolved big brains after big disasters

|

Scientists from Stony Brook University and the Max Planck Institute of Animal Behavior have pieced together a timeline of how brain and body size evolved in mammals over the last 150 million years. The international team of 22 scientists, including … Read More

Icy clouds could have kept early Mars warm enough for rivers and lakes

|

One of the great mysteries of modern space science is neatly summed up by the view from NASA’s Perseverance, which just landed on Mars: Today it’s a desert planet, and yet the rover is sitting right next to an ancient … Read More

A new perspective on the genomes of archaic humans

|

A genome by itself is like a recipe without a chef — full of important information, but in need of interpretation. So, even though we have sequenced genomes of our nearest extinct relatives — the Neanderthals and the Denisovans — … Read More

Genetic effects of Chernobyl radiation

|

In two landmark studies, researchers have used cutting-edge genomic tools to investigate the potential health effects of exposure to ionizing radiation, a known carcinogen, from the 1986 accident at the Chernobyl nuclear power plant in northern Ukraine. One study found … Read More
