UrduResearchers examine tool-sharing behaviors in wild chimpanzee populations. The social underpinnings of tool development in early human evolution are unclear, but understanding related behaviors in chimpanzees may provide insight. Stephanie Musgrave and colleagues compared how wild chimpanzees in the Goualougo…

Drivers of CO2 emissions in China
By combining data from population growth, energy intensity per unit of GDP, per capita GDP, and emission per unit of energy consumed, researchers determined the major drivers of energy-related CO 2 emissions in China since 1978, when the country experienced…
Threshold for Greenland ice sheet collapse
Researchers reconstruct the climate near southern Greenland during late Pleistocene interglacials. The complete melting of the Greenland Ice Sheet (GIS) could contribute up to 7 m of global sea-level rise. Understanding the GIS response to past interglacial periods could help…
Rhythmic movement in chimpanzees
A study explores how sound induces rhythmic movement in chimpanzees. Music influences rhythmic movement in humans, suggesting a link between the brain’s auditory and motor areas. Understanding chimpanzees’ predisposition to music could shed light on the evolutionary origins of humans’…
On-skin, passive-cooling electronics
Researchers report the development of breathable, waterproof, and recyclable on-skin electronics with passive-cooling capabilities. On-skin electronics with thermal management capabilities for body temperature regulation can improve user comfort and reduce energy consumption. Most such devices rely on joule heating, with…
Locomotion in late Miocene hominoid
A study provides insights into the locomotion of the late Miocene hominoid Oreopithecus bambolii. The skeleton of O. bambolii, a hominoid from Europe dating from 8.3 to 6.7 million years ago in the Late Miocene, is more complete than that…
People think marketing and political campaigns use psychology to influence their behaviors
A new study has shown that whilst people think advertising and political campaigns exploit psychological research to control their unconscious behaviours, ultimately they feel the choices they make are still their own. The research, led by Dr Magda Osman from…
California’s stricter vaccine exemption policy and improved vaccination rates

Stanford study finds whales use stealth to feed on fish
Small fish are speedy and easy to scare. So how is it that a giant humpback whale, attacking at speeds about as fast as a person jogs, is able to eat enough fish to sustain itself? Combining field studies, laboratory…

NFCR-funded translational cancer research project receives Virginia Catalyst grant
ROCKVILLE, MD – A translational research project supported by the National Foundation for Cancer Research (NFCR) has been awarded $700,000 from Virginia Catalyst to advance its lead cancer drug candidate. The funding will be used for collaboration among the laboratory…
How whales engulf fish
A study of anchovies’ escape behavior from virtually approaching predators suggests that while anchovies’ threshold of responses is sufficient for sea lion-sized predators, it is not surpassed for approaching whales until the whale rapidly expands its jaws, allowing for simultaneous…
Science Snapshots From Berkeley Lab

NUS researchers uncover how fish get their shape
A team of researchers from the Mechanobiology Institute at the National University of Singapore investigated the science behind the formation of the ‘V’ patterns – also known as chevron patterns – in the swimming muscles of fish. The study focused on the myotome (a group of muscles served by a spinal nerve root) that makes up most of the fish body. These fish muscles power the fish’s side-to-side swimming motion and the chevron pattern is thought to increase swimming efficiency. The research team found that these patterns do not simply arise from genetic instruction or biochemical pathways but actually require physical forces to correctly develop.

Therapy dog lifts patients’ hearts
Kepu Savou thought he had come down with a cold. When his symptoms persisted, he visited a doctor and learned that his heart was failing – something Savou never would’ve imagined at age 29.
He has been an inpatient at UW Medical Center, awaiting a donor heart for transplant. While the monthslong experience has been difficult, he says a program called Paws for Patients has provided much-needed emotional support. Program volunteers bring registered therapy dogs to visit patients who face challenging medical conditions.
