SYRACUSE, N.Y. - Researchers in the Department of Earth Sciences at Syracuse University have confirmed that rising oceanic and atmospheric oxygen levels co-evolved with marine life hundreds of millions of years ago.

Wanyi Lu, a Ph.D. candidate studying under associate professor Zunli Lu (no relation) in the College of Arts and Sciences, is the lead author of a groundbreaking paper in Science magazine (American Association for the Advancement of Sciences, 2018).

New research carried out by the John Innes Centre has delved into the genetic memory systems through which plants pass seasonal information down to their seeds to give them the best chance of reproductive success.

Plants integrate seasonal signals such as temperature and day length and use this memorised information to optimise the timing for key lifecycle stages.

Fires ignited by lightning have and will likely continue to increase across the Mediterranean and temperate regions in the Southern Hemisphere under a warmer climate, according to a new study co-led by a Portland State University researcher.

NASA's Terra satellite provided infrared data on Subtropical Depression Alberto when it was centered over Indiana and as it moved through the Ohio Valley.

On May 30, The National Weather Service (NWS) was issuing Flash Flood Warnings for portions of western Kentucky as well as from extreme northeast Georgia to western North Carolina. Flash Flood Watches are in effect for portions of the southern Appalachians and Lower Ohio Valley.

For centuries Inuit children in Greenland, Canada, and Alaska have been observed as small.
But recently they have begun to grow a lot.

»During the last couple of years people have noticed that Greenlandic boys and girls are getting taller compared to older generations. These common observations have now been scientifically proved,&laquo says Marius Kløvgaard, MD and one of the scientists behind a newly published study of growth of Greenlandic children.

Bioanalysis, a leading MEDLINE indexed journal for bioanalytical scientists, has published a Special Focus Issue on LC-MS assays impacting CYP and transporter DDI evaluations. The journal is published by Future Science Group.

The Special Focus Issue, guest Edited by Ragu Ramanathan (Pfizer), explores novel LC-MS assays impacting CYP and transporter DDI evaluations, through original research articles, as well as expert perspectives in the form of commentary-style articles.

Troy, N.Y. - Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1X10-47 square centimeters--one-trillionth of one-trillionth of a centimeter squared--the most stringent limit yet determined for dark matter as established by the world's most sensitive detector.

In a pilot study, researchers from North Carolina State University and Haverford College have used naturally arising acoustic vibrations - or sound waves - to monitor the state of granular materials. This passive approach represents a way to probe disordered or granular materials without disturbing them, and may enable researchers to forecast the failure of these materials.

The concept of survival of the fittest most often applies to the competition that occurs within and between animal species, but evolutionary pressures can be found elsewhere--even in a cancerous tumor.

Cancer researchers have come to understand tumors not as lumps of identical cells, but rather as diverse, dynamic populations unto themselves. And, like individuals within animal populations, cells within tumors compete with one another, some thriving, some failing.

A new study by Portland State University researchers finds billions of dollars could be saved if the nation's aging dams are removed rather than repaired, but also suggests that better data and analysis is needed on the factors driving dam-removal efforts.

The study, published online in May in the journal River Research and Applications, analyzed the best available national data to compare the trends and characteristics of dams that have been removed with those that remain standing.
