Montana seeks to end protections for Glacier-area grizzlies
Montana is asking the U.S. Fish and Wildlife Service to lift threatened species protections for grizzly bears in the northern portion of the state, including areas in and around Glacier National Park, officials said Monday......»»
Chiral TADF-active polymers for high-efficiency, circularly polarized organic light-emitting diodes
A beam of light can be divided into left-handed and right-handed polarized light by physical methods. Chiral fluorescent materials can emit different left-handed and right-handed polarized light when they are excited, which is called circularly polar.....»»
Footprints from site a at Laetoli, Tanzania, are from early humans, not bears
The oldest unequivocal evidence of upright walking in the human lineage are footprints discovered at Laetoli, Tanzania in 1978, by paleontologist Mary Leakey and her team. The bipedal trackways date to 3.7 million years ago. Another set of mysterious.....»»
Highlights of the day: Server makers may see chip shortage last into 2H22
Demand for servers remain robust, but component shortages have been undermining server shipments. Chip supply for servers is expected to persist into second-half 2022. TSMC is making progress in its advanced packaging technology. The foundry house ha.....»»
Server ODMs expect server component shortage to persist through 2H22
Quanta Cloud Technology (QCT), a subsidiary of Quanta Computer specializing in the manufacture of datacenter servers, expects chip shortages, particularly the shortage of power management ICs (PMIC), to persist through the second half of 2022......»»
Improving climate projections in the polar regions
The polar regions play a crucial role in balancing global climate—with the poles heating up much faster than the rest of the world. Yet, climate projections for these regions still have significant uncertainties. This is hampering efforts to curb c.....»»
Rare hunting scene raises questions over polar bear diet
A polar bear chases a reindeer into the water, drags it ashore and devours it, in a striking scene caught on film for the first time......»»
We identified who"s most at risk of homelessness and where they are. Now we must act, before it"s too late
Homelessness is traumatic. It affects not just housing arrangements but whether or not someone can get enough food, feel safe and maintain relationships with friends and family. The physical and mental health effects often persist long after people a.....»»
Arctic Ocean started getting warmer decades earlier than we thought, study finds
The Arctic Ocean has been getting warmer since the beginning of the 20th century—decades earlier than records suggest—due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean......»»
Enhanced triboelectric nanogenerators of polymeric sulfur blends with toxin-free synthesis
A triboelectric nanogenerator (TENG) is an energy-harvesting device that converts mechanical energy into electricity through contact separation or relative sliding movements of two opposite tribo-polar materials. Researchers from Inha University prev.....»»
France bans wild animals in circuses
French lawmakers voted on Thursday to end wild animals being used in live circus shows, spelling an end to performing tigers, lions or bears......»»
Why do brown bears frequent towns more than before?
Surveys have revealed an upward trend in the number of brown bears over the past three decades in Hokkaido, Japan's northernmost island. Researchers at Hokkaido University have been investigating the causes and implications of the increase......»»
Using virtual fluid for the description of interfacial effects in metallic materials
Liquids containing ions or polar molecules are ubiquitous in many applications needed for green technologies such as energy storage, electrochemistry or catalysis. When such liquids are brought to an interface such as an electrode—or even confined.....»»
Zhen Ding expects chip shortage to persist until end-2022
Shortages of certain chips and components are disrupting Zhen Ding Technology's PCB shipments to its major client in the US, and the company expects uneven inventories across different chip types to persist through the end of 2022......»»
First direct measurement of the overall impact of ocean eddy killing
Ocean currents, propelled by kinetic energy from the wind, are the great moderators of our climate. By transferring heat from the equator to polar regions, they help make our planet habitable......»»
Networking device makers expect chip shortage to persist in 2022
ICs manufactured with mature process nodes, particularly power management ICs (PMIC), MOSFET and Wi-Fi chips, are expected to remain in short supply until the middle of 2022, according to sources at networking device makers......»»
Server component shortage to last till mid-2022
Shortage of components for server production will persist through mid-2022 amid strong market demand for servers, and it remains to be seen whether the sector can reach a supply/demand balance in the second half of next year, according to supply chai.....»»
