Reproductive plasticity revealed: Neotropical treefrog can choose to lay eggs in water or on land

A new species of neotropical treefrog has been discovered that can reproduce both aquatic and terrestrial ways. Researchers found that this frog makes a behavioral decision to lay egg masses aquatically in a pond or terrestrially on overhanging plants, allowing it to avoid predators and extreme temperatures.

Study: Patients 75 years and older with brain tumors may benefit from more aggressive treatment

A new study found that elderly patients with brain tumors aged 75 and older do not receive aggressive treatments like younger patients. However, treating these patients aggressively with multi-modality therapies can lead to better survival rates without affecting mental abilities or causing unbearable side effects.
