How our ancestors were like gorillas

Research from University College London found that some of our closest extinct relatives had more in common with gorillas than previously thought. The study discovered that males continued to grow well into adulthood, leading to a significant size difference between males and females, similar to what is seen in gorillas.

Having the climate cake and eating it, too

A recent paper suggests that reducing carbon emissions from deforestation and degradation (REDD) could be key to addressing climate change. By including REDD in the Kyoto Protocol, developing countries can claim compensation for sustainable forest management, potentially earning $630 million annually.

Small RNA plays parallel roles in bacterial metabolism

A team from the University of Illinois identified SgrS, a 200-nucleotide-long RNA molecule, which performs two functions to regulate glucose metabolism in bacteria. The molecule binds to messenger RNA to inhibit new glucose transporter production and codes for a protein that retards existing transporter activity.

Recipe for a storm: The ingredients for more powerful Atlantic hurricanes

University of Wisconsin-Madison scientists have found that a basin-wide circulation pattern drives Atlantic hurricane activity. The study reveals that Atlantic hurricanes will be more sensitive to climate changes than storms in other ocean basins, with warmer oceans indicating ideal conditions for development. Understanding this relati...

MRE could provide a definitive diagnosis for people with muscle pain, Mayo Clinic study shows

Researchers at Mayo Clinic have developed a new imaging technology called magnetic resonance elastography (MRE) that can provide images of affected muscles with greater clarity than traditional MRI. This technology measures tissue elasticity and can detect abnormal hardening of tissues, which is a hallmark of myofascial pain syndrome.

Scientists solve cosmological puzzle

Researchers solved a longstanding problem of the Cold Dark Matter cosmology model by exposing a critical relationship between interstellar gas and dark matter in galaxy birth. The study showed that dense gas clouds in galaxies form massive stars, which drive 'sloshing' effects that kick dark matter out of the galaxy's center.

Antibody responses in patients with Lyme arthritis

Researchers found that joint inflammation persists in patients with antibiotic-refractory Lyme arthritis, despite the spirochetes being killed. Antibody titers declined to similar levels after 4-6 months of antibiotic therapy, regardless of treatment response.

10 myths and 1 truth about generalized HIV

Despite substantial progress against AIDS, the generalized HIV epidemic continues to rage on, driven by concurrent partnerships. Interventions such as abstinence and condom use have limited effectiveness in containing the spread of the disease, highlighting the need for a more nuanced approach to prevention.

New study shows low-income families face 3 barriers to health care

A recent study by Oregon Health & Science University finds that low-income families face three major barriers to healthcare: lack of insurance coverage, poor access to services, and unaffordable costs. Families with public health insurance often reported feeling unwelcome and having difficulty accessing care due to long travel distances.

Long-term improvement seen with hip replacement

A study found a long-term positive impact on physical functioning in patients with osteoarthritis who underwent hip replacement, but no significant improvement in vitality or mental health. Patients with more severe OA showed the most improvement in physical functioning.

Meniscal damage and the development of persistent knee pain

A study of over 3,000 adults found that meniscal damage is often present in knees with osteoarthritis, but not directly responsible for pain. The researchers suggest that treating OA as a whole-joint disorder may help clarify the relationship between meniscal damage and knee symptoms.
