Chimpanzees Plan Their Breakfast Time, Type and Location to Acquire Sufficient Food Intake

Chimpanzees Plan Their Breakfast Time and Location

New research from the Max Planck Institute for Evolutionary Anthropology shows that wild chimpanzees plan their breakfast time, type and location when food supplies are short. How do our close relatives, the chimpanzees, acquire sufficient food when times are lean? By studying wild chimpanzees in the Taï National Park in Côte d’Ivoire researchers of the […]

Power Conserving Chip May Increase Smartphone Battery Life

Power Conserving Chip May Increase Smartphone Battery Life

A new power-conserving chip developed by MIT spinout Eta Devices may increase smartphone battery life and save energy in cell towers. Stream video on your smartphone, or use its GPS for an hour or two, and you’ll probably see the battery drain significantly. As data rates climb and smartphones adopt more power-hungry features, battery life […]

Targeted Chemotherapy Delivery Could Kill Tumor Cells More Effectively

New Approach Could Kill Tumor Cells in the Brain More Effectively

New research shows that delivering chemotherapy directly into the brain cavity may kill tumor cells in the brain more effectively and avoid side effects. Every year, about 100,000 Americans are diagnosed with brain tumors that have spread from elsewhere in the body. These tumors, known as metastases, are usually treated with surgery followed by chemotherapy, […]

Targeted Isolation May Be the Most Effective Way to Reduce Transmission of Ebola

Isolation May Be the Most Effective Way to Reduce Transmission of Ebola

New research led by the Yale School of Public Health shows that isolating 75% of infected individuals in critical condition within four days of symptom onset has a high chance of eliminating the spread of Ebola. Isolating the most severely ill Ebola patients before the fifth day of their illness may be the most effective […]

Astronomers Measure the Size and Structure of a Nova’s Nuclear Blast

Astronomers Measure the Size and Structure of a Novas Nuclear Blast

For the first time, a team of astronomers has measured the size and structure of a nova’s nuclear blast as it happened. The discovery of Nova Delphini 2013, along with the data collected about it, could well sharpen or reshape our understanding of the nature of such blasts. The research appears online in the journal […]

Chandra Identifies the Impact of Turbulence on Star Birth

Turbulent Heating in Galaxy Clusters

Using data from NASA’s Chandra X-ray Observatory, a newly published study reveals evidence that heat channeled from turbulent motions in galaxy clusters is enough to offset radiative cooling and prevent the formation of stars. The same phenomenon that causes a bumpy airplane ride, turbulence, may be the solution to a long-standing mystery about stars’ birth, […]

Chandra Confirms Active Galactic Nuclei Downsizing

Modest AGN Tend to Peak Later in Cosmic History

A new study of 209 galaxies in the early universe with X-ray bright supermassive black holes reveals that more modest active galactic nuclei (AGN) tend to peak later in cosmic history, and that obscured and unobscured AGN evolve in similar ways. Supermassive black holes containing millions or even billions of solar-masses of material are found […]

Rutgers Study Shows Previous Climate Change Was Caused by the Ocean and the Atmosphere

Past Climate Change Was Caused by the Ocean and Atmosphere

New research from Rutgers University provides a deeper understanding of the mechanisms of climate change, revealing that circulation of the ocean plays an important role in regulating the climate. Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new […]

Chemists Reveal How Synthetic Collagen Fibers Self-Assemble

How Synthetic Collagen Fibers Self-Assemble

Two new researcher papers from Rice University detail how synthetic collagen fibers self-assemble via their sticky ends. Collagen is the most common protein in mammals, a major component of bone and the fibrous tissues that support cells and hold organs together. Discovering its secrets may lead to better synthetic collagen for tissue engineering and cosmetic […]
