Decades of Air Pollution Undermine the Immune System

The diminished power of the immune system in older adults is usually blamed on the aging process. But a new study by Columbia immunologists shows that decades of particulate air pollution also take a toll.

Morning Blue Light Treatment Improves Sleep In Patients With PTSD

University of Arizona Health Sciences researchers are exploring a noninvasive, drug-free treatment that offers hope for healing from the severe symptoms of post-traumatic stress disorder.

Bacterial Sensors Send a Jolt of Electricity When Triggered

Scientists and engineers at Rice University say the same is true for the environment. If a chemical spill in a river goes unnoticed for 20 minutes, it might be too late to remediate.

Researchers Develop Drug To Treat Alzheimer's Disease In Down Syndrome Patients

Research on the drug, known as DYR533, was conducted at the the University of Arizona R. Ken Coit College of Pharmacy and BIO5 Institute, in partnership with the Biodesign Institute in Phoenix.

Study Uncovers Widespread And Ongoing Clearcutting Of Swedish Old Forests

Almost one fourth of Sweden’s last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence for widespread cryptic forest degradation across the global north.

Why Some Latino Communities Fear the Covid-19 Vaccine, and What Can Be Done to Help

Amid the COVID-19 pandemic, some people in medically underserved Latino communities avoided getting vaccinated due to fears of side effects, mistrust of health officials and vaccine manufacturers and discrimination from health care workers, according to a new study from Rice University.

525-Million-Year-Old Fossil Defies Textbook Explanation For Brain Evolution

According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom.

Early Planetary Migration Can Explain Missing Planets

Model accounts for scarcity of planets with masses between super-Earths and mini-Neptunes

Alzheimer's Disease Can Be Diagnosed Before Symptoms Emerge

A large study led by Lund University in Sweden has shown that people with Alzheimer's disease can now be identified before they experience any symptoms. It is now also possible to predict who will deteriorate within the next few years. The study is published in Nature Medicine, and is very timely in light of the recent development of new drugs for Alzheimer's disease.

Altered Cell Behaviour Behind Resistance In Neuroblastoma

Researchers at Lund University in Sweden have identified one of the reasons why the childhood cancer neuroblastoma becomes resistant to chemotherapy. The findings are significant for how future treatments should be designed. The results have been published in Science Advances.

The Brain's Immune Cells Can Be Triggered To Slow Down Alzheimer's Disease

The brain's big-eating immune cells can slow down the progression of Alzheimer's disease. This is shown by a study that is now published in Nature Aging.

Giant Mantle Plume Reveals Mars Is More Active Than Previously Thought

Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity.

Seizures Happen Like Clockwork — but Depend on the Clock

Rice, UCSF statistical models show rhythmicity of seizures likely changes with age and common triggers

UArizona Expert Available To Discuss Biodiversity And Conservation Ahead Of COP15 Conference

TUCSON, Ariz. – While many governments, scientists and concerned citizens around the world have made efforts to conserve plant and animal species and promote biodiversity, some experts say it hasn't been enough.

Engineers Go Further with the Flow to Model Moving Cars and Tires

Mechanical engineers at Rice University and Waseda University in Tokyo have dramatically advanced their computational fluid dynamics models of airflow around a moving car and its tires.

Botanical Gardens Are 'Hot Spots' For Butterflies Amid Climate Change

Life in the concrete jungle can be rough, particularly for butterflies, but urban green spaces can hold surprising diversity and may become more important than ever in insect pollinator conservation, according to a new study from University of Arizona researchers.

Study Reveals How Ancient Fish Colonized The Deep Sea

The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington study led by Elizabeth Miller reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea.

Growing Pure Nanotubes Is a Stretch, but Possible

Rice theorists show how tight ‘diet’ could produce single-chirality carbon nanotubes

A Rough Morning At Home Can Lead To Employees Being More Helpful At Work

Employees often engage in "mood repair" after a tense morning with a partner, University of Arizona researchers say.

New Blood Test Can Detect ‘Toxic’ Protein Years Before Alzheimer’s Symptoms Emerge, Study Shows

Today, by and large, patients receive a diagnosis of Alzheimer’s only after they exhibit well-known signs of the disease, such as memory loss. By that point, the best treatment options simply slow further progression of symptoms.
