A new Antarctic ice sheet modeling study from scientists at UC San Diego’s Scripps Institution of Oceanography suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.  The model’s simulations suggest this effect is large enough to make a meaningful contribution to global sea-level rise under high greenhouse gas emissions scenarios.  The extra ice loss caused by this meltwater flowing out to sea from beneath Antarctic glaciers is not currently accounted for in the models generating major sea-level ...

ITHACA, N.Y. – More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell University-led research based on a first-of-its-kind exploration by an underwater robot. The remotely operated Icefin robot’s climb up and down a crevasse in the base of the Ross Ice Shelf produced the first 3D measurements of ocean conditions near where it meets the coastline, a critical juncture known as the grounding zone. The robotic survey revealed a new circulation pattern – a jet funneling water sideways through the crevasse – in addition to rising and sinking currents, ...

A team led by CNRS scientists1 has discovered that, just like humans, Guinea baboons develop complex strategies to select partners for cooperation, basing their decisions on past interactions. Humans naturally engage in strategic cooperation in many contexts. For example, when children help schoolmates by lending them their class notes, they may expect the same in return the next time: this is known as reciprocity. But if the favour is not returned, they are likely to seek others with whom to cooperate. The team’s findings ...

Imperial researchers have discovered a hidden mechanism within hair follicles that allow us to feel touch. Previously, touch was thought to be detected only by nerve endings present within the skin and surrounding hair follicles. This new research from Imperial College London has found that that cells within hair follicles – the structures that surround the hair fibre – are also able to detect the sensation in cell cultures. The researchers also found that these hair follicle cells release the neurotransmitters histamine and serotonin in response to touch – findings that ...

By April Toler More than two-thirds of the world’s population is expected to live in cities by 2050, according to the United Nations. As urbanization advances around the globe, researchers at the University of Notre Dame and Stanford University said the quality of the urban physical environment will become increasingly critical to human well-being and to sustainable development initiatives. However, measuring and tracking the quality of an urban environment, its evolution and its spatial disparities is difficult due to the amount of on-the-ground data needed to capture these patterns. To address the issue, Yong Suk Lee, assistant professor of technology, ...

UPTON, NY—Plant biologists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have engineered enzymes to modify grass plants so their biomass can be more efficiently converted into biofuels and other bioproducts. As described in a paper just published in Plant Biotechnology Journal, these enzymes modify molecules that make up plant cell walls to provide access to fuel-generating sugars normally locked within complex structures.  “The concept of biomass to biofuel seems simple, but it is technically very difficult to release the sugars,” noted Chang-Jun Liu, a senior plant biologist at Brookhaven ...

Ask a biologist why predators don't exterminate all their prey, part of the answer often is that there is an ongoing arms race between predators and prey, with both parties continuously evolving new ways to cheat each other. The hypothesis is particularly prevalent for bats and their prey; insects. 50 million years ago, the first bats evolved the ability to echolocate and thus hunt in the dark, and in response to this, some insects evolved ultrasound-sensitive ears so they could hear and evade the bats. But if there is an ongoing arms race, bats should have responded to this, says University of Southern Denmark biologist, associate professor and bat ...

Time-restricted eating, also known as intermittent fasting, can help people with Type 2 diabetes lose weight and control their blood sugar levels, according to a new study published in JAMA Network Open from researchers at the University of Illinois Chicago.   Participants who ate only during an eight-hour window between noon and 8 p.m. each day actually lost more weight over six months than participants who were instructed to reduce their calorie intake by 25%. Both groups had similar reductions in long-term blood sugar levels, as measured by a test of hemoglobin A1C, which shows blood sugar levels over the past three months.  The ...

About The Study: This 6-month randomized clinical trial involving 75 adults with type 2 diabetes found that a time-restricted eating diet strategy without calorie counting was effective for weight loss and lowering of hemoglobin A1c levels compared with daily calorie counting.
