Burst of morning gene activity tells plants when to flower

University of Washington

In a paper published Sept. 24 in the journal Nature Plants, researchers announced that the gene FT — the primary driver of the transition to flowering in plants each spring — does something unexpected in Arabidopsis thaliana plants grown in natural environments, with implications for the artificial growing conditions scientists commonly used in the lab.

Bat Genome Research May Reveal Clues to Longevity

Stony Brook University

Liliana M. Dávalos, PhD, a Professor in the Department of Ecology and Evolution at Stony Brook University received an NSF 'Understanding the Rules of Life' award and in a longevity study is analyzing the genomes of bats, small mammals with disproportionately long lives given their body size.

Physicists Train Robotic Gliders to Soar Like Birds

University of California San Diego

Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.

AI speeds effort to protect endangered elephants

Cornell University

Cornell University’s Elephant Listening Project tracks African forest elephants with acoustic sensors, but the forests are so remote and the sound files so huge it takes months to collect and analyze the data – too long to rescue the animals from poachers or other threats. Now scientists can learn critical information about the elephants’ habits and patterns in a fifth of the time. A startup, Conservation Metrics, developed a tool that uses artificial intelligence to distinguish the low-frequency, long-duration elephant calls from other rainforest sounds.

Migrating Monarchs Facing Increased Parasite Risks

University of Georgia

During their annual migration to wintering sites in Mexico, monarch butterflies encounter dangers ranging from cars and trucks to storms, droughts and predators. A study led by ecologists at the University of Georgia has found evidence that these iconic insects might be facing a new challenge.

Bird Communities Dwindle on New Mexico’s Pajarito Plateau

Los Alamos National Laboratory

Researchers have found declines in the number and diversity of bird populations at nine sites surveyed in northern New Mexico, where eight species vanished over time while others had considerably dropped.

When These Flies Want to Sniff Out Food and Mates, They Wing It

Ohio State University

Fruit flies don’t appear to use their tiny, translucent wings for optimal flight, as one might expect. The speedy appendages seem to be doing double duty, helping the insect sniff out food, mates and other important scents, according to new research from The Ohio State University.

For UW Physicists, the 2-D Form of Tungsten Ditelluride Is Full of Surprises

University of Washington

In a paper published online July 23 in Nature, a UW-led research team reports that the 2-D form of tungsten ditelluride can undergo "ferroelectric switching" — a first for a exfoliated 2-D material. Ferroelectric materials can have applications in memory storage, capacitors, RFID card technologies and even medical sensors.
