Making mice with enhanced color vision

Researchers created mice with both human and mouse visual receptors, allowing them to distinguish between previously indistinguishable colors. This breakthrough suggests the brain can adapt to new sensory information quickly, challenging the idea that early primates developed trichromatic vision gradually over time.

Phone-based therapy eases depression long term

A new study by Group Health researchers found that phone-based therapy can lead to long-term positive effects on depression symptoms. Patients who received telephone psychotherapy soon after starting antidepressant medication showed strong positive effects at 18 months, with 77 percent reporting improved depression symptoms.

The root of dyscalculia found

Researchers at UCL induce dyscalculia in normal subjects using TMS, finding a causal link between right parietal lobe malfunction and the math learning disorder. This breakthrough study has implications for diagnosis and treatment, potentially leading to earlier interventions and more effective remedial teaching.

The next great earthquake

A geophysicist from Rensselaer Polytechnic Institute urges officials to consider all subduction-type tectonic boundaries as lethal due to the unpredictability of massive earthquakes. The expert highlights the importance of warning systems and educational outreach to coastal communities to mitigate the impact of tsunamis.

New protein implicated in autism

A new protein, CADPS2, has been identified as a potential cause of autism. Research found that mice lacking this protein exhibited autistic-like characteristics, including impaired social interactions and hyperactivity.

Sutent achieves first line EAU approval for kidney cancer

The European Association of Urology (EAU) has recommended Sutent as a first-line treatment for patients with metastatic renal cell carcinoma. Clinical trials have shown that Sutent improves progression-free survival by more than doubling the median PFS compared to interferon-alpha. The new guidelines also highlight Sutent's higher obje...

Prenatal glucocorticoid exposure has been shown to have long-lasting deleterious effects on cardiovascular, metabolic, and neuroendocrine function in offspring. Additionally, research has identified a protein implicated in both autism and leukemia, with aberrant splicing detected in individuals with these conditions.

Leukemic cells find safe haven in bone marrow

Research at St. Jude Children's Research Hospital shows that leukemic cells receive a protective niche from bone marrow mesenchymal cells, which release the amino acid asparagine to help them survive treatment with asparaginase. This finding suggests new strategies for enhancing anti-leukemic drugs and reducing leukemia recurrence rates.
