A study in scarlet Japanese macaques

A team from Kyoto University's Primate Research Institute found that female red skin color acts as a 'badge' of their social status, not fertility. Female Japanese macaques with darker/redder hindquarters are of higher social rank.

Why is east Asian summer monsoon circulation enhanced under global warming?

A recent study published in Journal of Climate confirms that the Tibetan Plateau plays a key role in enhancing East Asian summer monsoon circulation under global warming. The study found that enhanced latent heating over the plateau stimulates cyclone anomalies, leading to stronger southerly winds in East Asia.

Cave droplets provide window into past climates

Scientists analyzed oxygen isotopes in stalactites and stalagmites from 39 caves worldwide to understand past groundwater recharge. The study found that cave drip water oxygen composition varies between cool and warm climates, providing insights into climate variability and water resources.

No escape for mosquitoes

Researchers discovered that the Venus flytrap's tactile sensors respond to minute pressure stimuli, converting them into electrical signals that cause the trap to close. The plant has evolved smaller traps to detect the smaller forces generated by lightweight mosquitoes.

CNIC is the coordinator of an international consensus document on the use of magnetic resonance

A new international consensus document provides guidelines for the conduct of magnetic resonance imaging studies after a myocardial infarction. The main outcome measure recommended is absolute infarct size, with scanning timing between 3 and 7 days post-infarction.

Study shows potential for reduced methane from cows

A study by the University of Adelaide and international researchers has shown that it is possible to breed cattle with reduced methane emissions. The genetics of an individual cow strongly influence the make-up of microorganisms in its rumen, allowing for selection of cows with lower levels of methane-producing bacteria.

Cancer genes and the tumor milieu

A recent study by Chiaki Takahashi at Kanazawa University discovered that the cancer gene RB promotes tumor growth by altering the tumor microenvironment (TME). The TME changes enable the accumulation of immunosuppressive cells, which overpower the body's natural defense system.

Good home learning in early years boosts your secondary school achievements

A new study published in School Effectiveness and School Improvement found that pre-schoolers whose parents regularly read and talked about books with them scored better on math tests at age 12. The study, led by Dr. Simone Lehrl of the University of Bamberg, assessed 229 German children from age three until secondary school.

Robot uses machine learning to harvest lettuce

A robot developed by the University of Cambridge has successfully harvested iceberg lettuce in various field conditions, demonstrating potential for expanding robotics in agriculture. The 'Vegebot' uses machine learning to identify healthy lettuces and cut them without crushing, reducing physical demands on manual harvesting.

Data demonstrate efficacy of more flexible dose of regorafenib to relieve side-effects in mCRC patients

A study at ESMO World Congress on Gastrointestinal Cancer 2019 found that a more flexible dosing regimen for regorafenib improves patients' quality of life while maintaining its efficacy. The reduced and intermittent dose groups showed numerical improvements in tolerance to side effects such as fatigue and hand-foot syndrome.

The global tree restoration potential

A new study by the Crowther Lab suggests that global forest restoration could capture two-thirds of human-made carbon emissions. The study found that there is potential to increase the world's forest land by a third without affecting cities or agriculture, with forests capable of storing 205 billion tonnes of carbon once mature.

How trees could save the climate

A new study by ETH Zurich reveals that reforestation efforts could store two-thirds of the 300 billion tonnes of carbon released into the atmosphere since the Industrial Revolution. The greatest potential for forest restoration lies in six countries: Russia, US, Canada, Australia, Brazil, and China.

The Lancet: Nerve transfer surgery restores hand function and elbow extension in 13 young adults with complete paralysis

A novel surgical technique connects functioning nerves with injured nerves to restore power in paralyzed muscles, enabling participants to perform everyday tasks independently. The study suggests that nerve transfers can achieve similar functional improvements to traditional tendon transfers, with the benefit of smaller incisions and s...
