How introductory courses deter minority students from STEM degrees

A new paper in PNAS Nexus, published by Oxford University Press, indicates that minority students who earn low grades in introductory science, technology, engineering, and math classes are less likely to earn degrees in these ...

Researchers reconstruct the genome of the common ancestor of all mammals

Every modern mammal, from a platypus to a blue whale, is descended from a common ancestor that lived about 180 million years ago. We don't know a great deal about this animal, but the organization of its genome has now been ...

Researchers discover new predator damaging our ecosystems

For Arizona State University's Ph.D. recent graduate Julie Bethany Rakes, it all started as a failed experiment that ended up being an impactful discovery for the microbiology community. Recently in Nature Communications, ...

Evidence of the use of baby carriers 10,000 years ago

It seems logical enough: even in their earliest history, humans must have needed something to carry their babies around in as they moved from place to place. But because little hard evidence of this exists—no infant-sling ...

New strategy to precisely target subtypes of key protein

Cyclosporine is one of the most common and effective immunosuppressant drugs used to treat chronic diseases like arthritis and psoriasis, but it comes with a risk of serious side effects. Scientists think that may be because ...

Researchers unlock a new method for testing protein-based drugs

New Jersey Institute of Technology (NJIT) researchers have unveiled a new lab technique they say represents a "paradigm shift" in how pharmaceutical laboratories test and produce new protein-based drugs, such as therapeutic ...

Researchers identify African dust by measuring isotopes

Every summer, weather forecasters blast news about African dust plumes crossing the southern United States. And to most people, it's just dust, but to researchers at Texas A&M University, it's much more.

Determining how and why cells make decisions

Cells are constantly making decisions that lead to differentiation. For instance, cells in an embryo make a series of decisions that determine whether they will become neurons in some cases and muscle cells in others. How ...

Fasting-mimicking diet reduces signs of dementia in mice

Cycles of a diet that mimics fasting appear to reduce signs of Alzheimer's in mice genetically engineered to develop the illness, according to a new USC Leonard Davis School of Gerontology-led study.

Novel imaging system could mean near-instant biopsy results

Medicine has advanced dramatically during the last century. But when it comes to getting biopsy results, very little has changed. Consider, for example, what happens when a patient comes in to have a skin lesion biopsied ...

Climate change is turning trees into gluttons

Trees have long been known to buffer humans from the worst effects of climate change by pulling carbon dioxide from the atmosphere. Now new research shows just how much forests have been bulking up on that excess carbon.

Quantum effects in memristive devices

At the nanoscale, the laws of classical physics suddenly become inadequate to explain the behavior of matter. It is precisely at this juncture that quantum theory comes into play, effectively describing the physical phenomena ...

Exploring the reality of unread Stasi files

Many people—including public figures such as Nobel Laureate Günter Grass, former West German chancellor Helmut Schmidt, and trade union leader Claus Weselsky—choose not to read their Stasi files. How can this behavior ...

Underwater heat 'inferno' ravages Mediterranean corals

In the temperate shallows of the Mediterranean, once-vibrant red and purple coral forests that provide a crucial haven for biodiversity now stand bleached and brittle, transformed into skeletons by record summer temperatures, ...

Diverse landscapes at the heart of bee conservation

New research from the University of Georgia revealed that mixed land use—such as developments interspersed with forest patches—improves bee diversity and is leading to new solutions for bee conservation.
