Alzheimer's disease may look similar from one person to another even when different biological processes are driving the damage, according to a new study led by researchers at the University of California, Irvine.

In 2022, the U.S. Supreme Court's Dobbs v. Jackson Women's Health Organization decision allowed states to enact laws that ban or severely restrict abortion. Four years later, a study led by Harvard Medical School researchers at Beth Israel Deaconess Medical Center shows that the

As new Alzheimer's drugs move from clinical trials into everyday care, families are asking whether these treatments are safe, how long patients can stay on them and whether they truly slow the disease outside tightly controlled studies.

After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that treatment is working. A recent real-world study indicates that reaching a PSA level below 0.2 ng/mL is an indicator of improved patient survival. The

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Ele

A research team led by Professor Hyoyoung Lee of the Department of Chemistry at Sungkyunkwan University has developed a new catalyst that converts carbon dioxide into ethanol with high selectivity. The study, titled "Atomic-scale Cu–Zn synergy directs asymmetric C–C coupling for

A study by La Trobe University researchers has found annual ryegrass, the most damaging weed in Australian grain systems, can adjust its growth and reproduction to survive under drought stress, making it potentially harder to manage as climate conditions become more variable.

The effects of climate change extend far beyond rising temperatures. As forests and other vegetation respond to a warming world, they also change the amount of biogenic emissions released into the atmosphere, influencing the formation of ozone (O3) and fine particulate pollution.

Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane pollution in the U.S. and elsewhere may be dramatica

Human-caused climate change doubled the likelihood of the tinderbox weather conditions that sparked Canada's massive summer wildfires and in turn angered U.S. President Donald Trump, according to a study released Thursday.

A global analysis of range-shift records for 1,758 butterfly species—10% of known butterfly species—found that 80% had expanded their range and that 79% of all recorded range shifts were linked to climate change and extreme weather events. The new study, published in Nature Ecolo
