Managing blood pressure in barbershops yields substantial improvements

A study presented at the American College of Cardiology's Annual Scientific Session found that African-American men who received frequent monitoring and medication management from a specially-trained pharmacist in their barbershop saw a marked drop in blood pressure, with systolic blood pressure dropping by an average of 21 mm Hg. The ...

Digging up the Precambrian

Fossilized burrows from the late Ediacaran period show earlier origins of animal behavior, challenging previous theories. The discovery of large-sized, penetrative trace fossils indicates a radical transformation in marine ecosystems during this time.

Mexico well ahead of US in LGBT rights

A new study by University of Vermont professor Caroline Beer reveals that Mexico is more progressive than the US when it comes to LGBT rights. In contrast to the US, where religion suppresses LGBT rights, Mexico sees a positive correlation between liberal governance and increased LGBT-friendly legislation.

Elephant declines imperil Africa's forests

A Duke University study found that reduced forest elephant populations will lead to significant changes in tree species composition and structure, as well as understory density and nutrient availability. Without intervention, up to 96% of Central Africa's forests may undergo major transformations.

Plants overcome hunger with the aid of autophagy

Researchers at Tohoku University discovered that plants activate autophagy in leaf cells to derive essential amino acids during periods of low sunlight. This process allows plants to survive and grow under conditions of energy scarcity, enabling them to adapt to environmental challenges.

Polymer nanoparticle shows ability to locate and treat breast tumors

Researchers at Wake Forest Baptist Medical Center have developed a fluorescing nanoparticle that can find tumors and generate heat to destroy cancer cells. The nanoparticles, called Hybrid Donor-Acceptor Polymer Particles (H-DAPPs), successfully localized and killed breast cancer in mice, showing potential for future human trials.

Can pursuing happiness make you unhappy?

A study published in Psychonomic Bulletin & Review found that people who pursue happiness often feel like they do not have enough time, which paradoxically makes them feel unhappy. This effect is due to the pursuit of happiness causing participants to think of time as scarce.

Riding the (quantum magnetic) wave

Scientists have successfully converted quantum waves into electrical current using an organic-based magnet, paving the way for faster and more efficient electronics. The breakthrough, achieved by researchers at the University of Utah, could lead to new generations of electronic systems that use magnons instead of electrons.

Glass matters

The chemical topology of silica surfaces can significantly impact the effectiveness of various chemical processes, including catalysis, filtration, and nanofabrication. Researchers found that hydrophilic silanol groups attract water molecules, forming a barrier that reactants must overcome to proceed with the desired process.

Movable silicon 'lenses' enable neutrons to see new range of details inside objects

Researchers at NIST and NIH developed a new method that uses movable silicon gratings to focus neutron beams, allowing for the examination of objects at unprecedented scales. This breakthrough could complement existing scanning techniques, enabling scientists to probe the interiors of materials without damaging them.

Mutating Ebola's key protein may stop replication

Researchers at Purdue University may have discovered a way to stop Ebola virus replication by mutating its most important protein, VP40. The study found that altering the amino acid sequence of VP40 reduces lipid binding and prevents viral budding, offering new targets for therapeutics.

The Great Recession took a toll on public health, study finds

A new UCLA-led study finds that the Great Recession was associated with increased blood pressure and glucose levels, particularly among older homeowners and those still in the workforce. The study analyzed data from the Multi-Ethnic Study of Atherosclerosis and suggests that economic crises can have measurable effects on public health.

In the eye of the medulloblastoma

Researchers from CNRS and St. Jude Children's Research Hospital have identified a gene cluster involved in medulloblastoma tumour development. They found that genes normally expressed only in the eye can be activated in brain tumors, promoting cell proliferation and inhibiting cell death.
