One sea sponge turned out to be 2,000 years old. And older giant barrel sponges appear to have a faster rate of cell division, unlike us. They produce antibiotics and much, much more. Lina Bayona Maldonado studied how the differences in such factors as age or oceanic depth affect the production of all those substances. Ph.D. defense on 22 April.

A team of researchers from the National University of Singapore (NUS) has recently developed a simple solution to address two of the world's biggest problems—water scarcity and food shortage. They created a solar-powered, fully automated device called "SmartFarm" that is equipped with a moisture-attracting material to absorb air moisture at night when the relative humidity is higher, and releases water when exposed…

Many Australian school kids could be learning in classrooms with poor indoor air quality that exceeds safety guidelines.

Policymakers are under intensifying pressure to deliver on promises made as part of the Paris Agreement ahead of this year's COP26.

Circularly polarized light exhibits promising applications in future displays and photonic technologies. Traditionally, circularly polarized light is converted from unpolarized light by the linear polarizer and the quarter-wave plate. During this indirectly physical process, at least 50% of energy will be lost. Circularly polarized luminescence (CPL) from chiral luminophores provides an ideal approach to directly…

Classical hydrodynamics laws can be very useful for describing the behavior of systems composed of many particles (i.e., many-body systems) after they reach a local state of equilibrium. These laws are expressed by so-called hydrodynamical equations, a set of mathematical equations that describe the movement of water or other fluids.

Tropical Cyclone Seroja battered parts of Western Australia's coast on Sunday night, badly damaging buildings and leaving thousands of people without power. While the full extent of the damage caused by the Category 3 system is not yet known, the event was unusual.

Two snowstorms are barreling down on Denver this week. The first storm should arrive later Tuesday and another round Thursday evening.

A new study led by Stockholm University Assistant Professor Christian Stranne shows that thick sea ice outside the fjords can actually increase the sensitivity of Greenlandic fjords to warming. Stranne and a team of researchers from Sweden, Greenland, the Netherlands, the U.S. and Canada have reported on expeditions to two distinct fjords in northern Greenland during the 2015 and 2019 summers.

The stage is set for an escalation of extreme dry conditions, with widespread water restrictions expected and yet another dangerous fire season ahead.

Sunnier areas are associated with fewer deaths from COVID-19, an observational study suggests. Increased exposure to the sun's rays -- specifically UVA -- could act as a simple public health intervention if further research establishes it causes a reduction in mortality rates, experts say.

New research describes the unknowns in our knowledge of solar geoengineering.

Just exactly how does the Dyson Purifier Hot+Cool Formaldehyde improve on the current Dyson Purifier?

Excessive CO2 emissions are a major cause of climate change, and hence reducing the CO2 levels in the Earth's atmosphere is key to limiting adverse environmental effects. Rather than just capture and store CO2, it would be desirable to use it as carbon feedstock for fuel production to achieve the target of "net-zero-emissions energy systems." The capture and conversion of CO2 (from fuel gas or directly from the…

After the most active hurricane season on record in 2020, hurricane forecasters on Thursday said we can expect above-average activity again this year.

Researchers succeed in producing rapid, cost-effective and environmentally friendly material.

About a year ago, as the world experienced the deadly "first wave" associated with the coronavirus pandemic, many struggled to separate accurate from inaccurate information. While many well-meaning…

Study shows highest warming scenario would put 34% of Antarctic's ice shelf area at risk of fracture and collapse from melting and run-off - including 67% of the Antarctic Peninsular ice shelf area. This would allow glaciers to flow freely into the sea causing sea level rise.
